Reusable Bag Holder and System and Method of Using the Same

[0001] This application claims priority from U.S. Provisional Patent Application Ser. No. 61/946,627, filed Feb. 28, 2014, entitled “Reusable Bag Holder and System,” the entire disclosure of which is hereby expressly incorporated by reference in its entirety.

[0002] Embodiments of the present invention generally relate to a reusable bag with compartments, and more specifically to a reusable bag holder and system.

[0003] Consumers often bring home merchandise in disposable paper or plastic shopping bags because they do not bring their own reusable bags to the store. The manufacture and disposal of these paper and plastic disposable bags places a burden on the environment because timber, petroleum, and energy must be used the make the disposable bags, landfills must be used to dispose of the bags, and pollution is created in both the manufacturing and disposal processes. The public has become increasingly more aware of the environmental problems associated with disposable bags. That is why some cities have banned certain disposable bags and some cites and countries require that stores charge consumers for each disposable bag they receive from a store.

[0004] Although reusable bags have been developed and improved over the years, they are still somewhat slow to catch on. There are many reasons why consumers do not use reusable shopping bags. One reason is consumers find it difficult to bring more than one reusable bag to the store because holding multiple bags is awkward and cumbersome. Furthermore, storing more than one reusable shopping bag in a consumer's car, bike, moped, etc. is also awkward and difficult. The two or more shopping bags may slide around the trunk of the consumer's car, may take up precious space in the back of a minivan or SUV, and may not fit in the consumer's bike basket. Additionally, reusable bags are not designed to store other reusable bags and purchased items. Most reusable shopping bags have only one main compartment and no pockets or separators to organize purchased items.

[0005] Accordingly, there exists a significant need for a reusable shopping bag system that will hold multiple reusable bags and purchased items. These and other needs are addressed by the various embodiments and configurations of the present invention. Thus, this invention relates to a novel system, device, and method for providing a bag with compartments to hold reusable shopping bags. The novel bag holder and system provided herein allow a user to neatly contain reusable shopping bags.

[0006] The novelty of the present invention relates to: (1) a device and system comprising a bag with compartments, which neatly and cleanly contain reusable shopping bags within the bag; (2) a device and system for containing reusable shopping bags within a user's car, bike, and/or shopping cart; and (3) a method of using the bag with compartments to contain reusable shopping bags.

[0007] Thus, it is one aspect of various embodiments of the present invention to provide a reusable shopping bag system that holds multiple reusable bags and that may be used to hold purchased items. Accordingly, the system can be used to hold reusable bags and to hold various types of purchased items, e.g., frozen food, produce, bread, canned goods, beverages, paper goods, cleaning supplies, shoes, clothing, etc. In one embodiment, the reusable shopping bag system comprises a main bag and one or more secondary bags. The secondary bags may include a reusable bag, a reusable freezer bag, and a reusable produce bag.

[0008] It is another aspect of embodiments of the present invention to provide a shopping bag system that neatly contains and stores multiple reusable bags within the user's car, shopping cart, bike basket, trunk, etc. Therefore, bags are not floating around a consumer's trunk or back seat. The bags are contained within a bag holder or another reusable bag and the system is readily folded and stored in a relatively small space. One advantage of some embodiments is that the shopping bag system neatly contains multiple reusable bags within the user's car, shopping cart, bike basket, trunk, etc. Some embodiments further include interconnection features for securing the system to the inside of the user's car, trunk, and/or shopping cart.

[0009] It is one aspect of embodiments of the present invention to quickly and easily store and remove reusable bags. Thus, various embodiments of the present invention allow a user to quickly insert and remove reusable bags into a main bag or other reusable bag holder.

[0010] It is another aspect of various embodiments to provide a reusable shopping bag storage system comprising a main bag and secondary bags made of a renewable material. Such materials may include bamboo, cotton, paper, rayon, and the like.

[0011] It is an aspect of some embodiments of the present invention to provide a reusable shopping bag holder and system that is reusable and withstands wear and tear such that the reusable shopping bag holder and system can be used over and over again. Thus, in one embodiment, the reusable shopping bag holder and/or one or more of the reusable shopping bags can be made out of non-woven laminate, non-woven polypropylene, or woven nylon.

[0012] It is one aspect of various embodiments to provide a reusable shopping bag storage system that comprises a main bag with pockets and compartments and one or more secondary bags. The pockets may be internal or external pockets. In some embodiments, the pockets hold bags (reusable or disposable). In additional or alternative embodiments, the pockets can hold keys, phones, tablets, wallets, billfolds, coupons, etc.

[0013] One aspect of embodiments of the present invention is to provide a reusable shopping bag storage system that allows for cleaning and/or sanitizing the reusable bags after each use. Another aspect is to provide a reusable shopping bag storage system that prevents, or at least hinders, build up of germs, microorganism, dirt, stains, grime, etc. Further, a reusable shopping bag system where any portion or all of the bag system may be machine washed if it should become soiled is provided.

[0014] It is one aspect of embodiments to provide a reusable shopping bag storage system that also reminds a user to remove the system from the user's car or other vehicle before entering a store. Thus, in one embodiment, the primary bag may include a chip or other processor that communicates with the user's phone, tablet, smart watch, vehicle infotainment system (e.g., car's audio an navigation system), etc. to remind the user to take the reusable shopping bag storage system into the store.

[0041] FIG. 2 shows a front perspective view of the main holder bag 10 according to one embodiment. The primary bag 10 can be a reusable bag that is a part of a reusable shopping bag system. The primary bag 10 may have a front panel 6 (also called a front portion herein) opposite a back panel 16 (also called a back portion herein), two side panel 2 (also called side portion herein) between the front panel 6 and back panel 16, and a bottom panel 4 (also called a bottom portion herein). The front panel 6, two side panel 2, back panel 16, and bottom panel 4 each have an inner surface and an outer surface. The primary bag 10 may also have vertical corners between the front 6, back 16, and side 2 panels and horizontal corners between the bottom panel 4 and the front 6, back 16, and side 2 panels. The horizontal corners are positioned around a bottom end (also called a first end or a closed end herein) between the bottom 4 and the sidewalls (e.g., the sides 2, front 6, and back 16). The primary bag 10 also has a top end (also called a second end or an open end herein) with top edges. Additionally, the front panel 6, two side panels 2, back panel 16, and bottom panel 4 are interconnected such that their inner surfaces form an interior cavity with an open end proximate the top end and top edges and a closed end proximate to the bottom panel 4.

[0042] In some embodiments, the primary bag 10 has four generally rectangular sidewall panels 6, 2, 16 forming a perimeter wall that extends along a central axis. A rectangular end panel or bottom panel 4 is interconnected to the perimeter at one end and the opposite end is left open to form an opening into a cavity. The perimeter wall may be formed from a rectangular piece of fabric that is folded at the vertical corners and closed upon itself to allow opposite ends to be sewn or interconnected together along an axially extending seam to form a rectangular cross-sectioned perimeter.

[0043] In some embodiments, a top edge of one or more panels 6, 2, 16 is folded down and inward along a circumferentially extending fold line, substantially parallel to the horizontal corners, and sewn at the top fold stitching line 70 to the respective panel 6, 2, 16 to create a strengthening and stiffening hem 18 with a height. In one embodiment, the front panel 6 and the back panel 16 each have a stiffening hem 18 proximate to the open end and that is glued or sewn at the top fold stitching line 70. In additional or alternative embodiments, the upper edges of the side panels 2 also have a folded section that is sewn or glued at the top fold stitching line 70 to create a strengthening and stiffening hem 18 with a height. In one embodiment, the height of the stiffening hem 18 is between about 2.5 inches and about 0.5 inches. In a preferred embodiment, the height of the stiffening hem 18 is between about 1.5 inches and about 0.75 inches. In a more preferred embodiment, the height of the stiffening hem 18 is about 1 inch.

[0044] For support and to add structure, the primary bag 10 may have wires, dowels, rods, tubes, bars, strengthening and stiffening hems, tubing, piping, or other stiffening mechanisms or support elements to keep the bag 10 standing upright and/or open. In the embodiment shown, the primary bag 10 has side piping 60 along one or more vertical corners of the bag 10 and bottom piping 62 along one or more horizontal corners of the bag 10. In one embodiment, the piping is a woven nylon material for strength and to reduce fraying. In other embodiments, the piping can be another material, such as another woven material, a non-woven material, or any other material known in the art. Piping or other support elements may also be positioned in the upper edges of the bag 10. The support elements or piping 60, 62 may be glued or sewn into the main bag 10 or they may be slid into channels via openings in the corners. In some embodiments, the support elements are removable. Having the support elements in the vertical and/or horizontal corners allows the bag 10 to fold flat but also stand upright when need be.

[0045] The primary bag 10 has a height H1, a length L1, and a width W1. In one embodiment, the height H1 of the primary bag 10 is between about 10 inches and about 18 inches. In a preferred embodiment, the height H1 of the primary bag 10 is between about 12 inches and about 16 inches. In a more preferred embodiment, the height H1 of the primary bag 10 is between about 13 inches and about 15 inches. In a most preferred embodiment, the height H1 of the primary bag 10 is about 14 inches. In one embodiment, the length L1 of the primary bag 10 is between about 6 inches and about 12 inches. In a preferred embodiment, the length L1 of the primary bag 10 is between about 8 inches and about 10 inches. In a more preferred embodiment, the length L1 of the primary bag 10 is about 9 inches. In one embodiment, the width W1 of the primary bag 10 is between about 5 inches and about 9 inches. In a preferred embodiment, the width W1 of the primary bag 10 is between about 6 inches and about 8 inches. In a more preferred embodiment, the width W1 of the primary bag 10 is about 7 inches.

[0046] In a second embodiment, which may have four compartments 14 and a channel 58, the height H1 of the primary bag 10 is between about 10 inches and about 18 inches. In a preferred embodiment, the height H1 of the primary bag 10 is between about 12 inches and about 16 inches. In a more preferred embodiment, the height H1 of the primary bag 10 is between about 13 inches and about 15 inches. In a most preferred embodiment, the height H1 of the primary bag 10 is about 14 inches. In one embodiment, the length L1 of the primary bag 10 is between about 5 inches and about 9 inches. In a preferred embodiment, the length L1 of the primary bag 10 is between about 6 inches and about 8 inches. In a more preferred embodiment, the length L1 of the primary bag 10 is about 7 inches. In one embodiment, the width W1 of the primary bag 10 is between about 4 inches and about 8 inches. In a preferred embodiment, the width W1 of the primary bag 10 is between about 5 inches and about 7 inches. In a more preferred embodiment, the width W1 of the primary bag 10 is about 6 inches.

[0047] The primary bag 10 can have a pocket 8 to hold a user's wallet, phone, billfold, coupons, keys, sunglasses, shopping list, etc. The pocket 8 may be on the front 6, back 16, or a side 2 of the primary bag 10. Further, the pocket 8 may be on an outer surface of the bag 10 or on the inside of the bag 10, for example on an inner surface of a panel 2, 6, 16 or on a surface of a channel wall. Additionally, the bag may have two or more pockets 8 for holding a user's personal items or small shopping items (e.g., gum, candy, greeting cards). Thus, one pocket 8 can be on a front panel 6 of the bag 10 and a second pocket (not shown) can be on a back panel 16 of the bag 10. In one embodiment, the pocket 8 is interconnected to the outer surface of the front portion 6. The pocket 8 can extend along the front panel of the main bag 10 from the closed end at the bottom 4 to the opposite open end. In other embodiments, the pocket 8 does not extend all the way to the open end of the primary bag 10. Thus, the pocket 8 may not extend up the entire height H1 of the primary bag 10. Therefore, in one embodiment, the pocket height P1 is between about 8 inches and about 14 inches. In a preferred embodiment, the pocket height P1 of the primary bag 10 is between about 10 inches and about 12 inches. In a more preferred embodiment, the pocket height P1 of the primary bag 10 is about 11 inches. In some embodiments, the pocket 8 extends from the lower end of the front portion 6 up a pocket height P1. The pocket 8 is interconnected to the primary bag 10 on three sides of the pocket 8. The pocket 8 may be the same material as the primary bag 10 or the pocket 8 can be a different material. Additionally, the pocket 8 may be the same color as the primary bag 10 or the pocket 8 can be a different color and even have a different design or pattern than the other outer surfaces of the primary bag 10. The pocket 8 may be large enough to store at least one secondary bag 20, 30, 40, and specifically may be large enough to store a reusable produce bag 40.

[0048] In some embodiments, the main bag 10 also has one or more handles 12, one or more pockets 8, and/or interconnection devices, such as zippers, Velcro, tabs, or clips. In the embodiment shown, the primary bag 10 includes a pair of carrying handles 12. Each handle 12 has a first end and a second end. The first end of the first handle 12 and the second end of the first handle 12 can be interconnected to the upper end or edge of the front panel 6 proximate the open end. In some embodiments, the first and second ends of the first handle 12 are interconnected to an inner surface of the front panel 6. The first handle 12 ends can be interconnected to the front panel via reinforced cross-stitching 54 or other interconnection means, such as adhesives, bonding, stitching, and the like. The first end of the second handle 12 and the second end of the second handle 12 can be interconnected to the upper end or edge of the back panel 16 proximate the open end. In some embodiments, the first and second ends of the second handle 12 are interconnected to an inner surface of the back panel 16. The second handle 12 ends can be interconnected to the back panel via reinforced cross-stitching 56 or other interconnection means, such as adhesives, bonding, stitching, and the like. In other embodiments, the handles 12 may be stapled, hooked, etc. to the bag 10 or may be interconnected using snaps, buckles, zippers, or other fastening elements. In various embodiments, the handles 12 may be interconnected on an outer surface of the bag 10. Further, the height of the cross-stitching 54, 56 can be the same as the height of the stiffening hem 18.

[0049] In one embodiment, the handles 12 are comprised of a woven material, which can be woven nylon. Woven nylon tends to fray less than other materials used in the art. In an alternate embodiment, the handles 12 are comprised of a non-woven polypropylene material. In one embodiment, the handles 12 may be ropes, chains, or other strong material. The design of the bag 10, handles 12, material of the bag 10, material of the handles 12, and additional support elements allow the primary bag 10 to hold approximately 30 lbs to 50 lbs of weight.

[0050] In one embodiment, the carrying handles 12 are short for holding the handles 12 in a user's hands. For example, the short handles are about 8 inches to about 20 inches long in some embodiments, or about 12 inches long in a preferred embodiment. In another embodiment, the carrying handles 12 are long for putting the handles 12 over the user's shoulder. For example, the handles 12 are about 16 inches to about 34 inches long in one embodiment; about 22 inches to about 28 inches long in a preferred embodiment; or about 25 inches long in a more preferred embodiment. Each handle 12 has opposite ends respectively, secured to the sidewall 6, 16 to form a flexible loop that is easily extended when the bag 10 is carried or conveniently rolled or folded inside the main bag 10 for storage. In one embodiment, each handle 13 encircles the bag to provide extra support for carrying heavy items. In one embodiment, the handles 13 are 20″ long.

[0051] In some embodiments, the handles 12 may comprise an interconnection device 64 with snaps, hook and loop material (e.g., Velcro), or other connection mechanisms to detachably interconnect the handles 12 together for easy carrying and to contain the handles 12. The interconnection device 64 can also be used to detachable secure the primary bag 10 and/or system 1 to a user's car, trunk, or shopping cart (see FIG. 9). See the description associated with FIG. 3 for more information on the interconnection device.

[0052] The primary bag 10 further comprises dividers 130 forming compartments 14 within the cavity of the primary bag 10. The primary bag 10 can have any number of compartments 14, for example, two, three, four, six, eight, ten, or twelve compartments, which can be formed by permanent, moveable, or removable dividers 130 or walls. The dividers 10 can be made of the same material as the main bag 10 or the dividers can be made of a stronger and/or stiffer material than the main bag. In some embodiments, one or more dividers 130 are sewn with stitching 50, 52 to one or more sidewalls 2, 6, 16 of the primary bag 10 to form compartments 14 for storing secondary bags 20, 30, 40 and other items. Each compartment 14 is large enough to store at least one secondary bag 20, 30, 40.

[0053] In one embodiment, the dividers 130 extend from the closed end at the bottom 4 of the primary bag 10 to the opposite open end proximate the upper edge. In another embodiment, the dividers 130 extend from a point above the closed end at the bottom 4 of the primary bag 10 to a point below the opposite open end, as at least partially shown in FIG. 2. In one embodiment, the dividers 130 extend from between about 2 inches and about 6 inches above the closed end at the bottom 4 of the primary bag 10 to a point between about 0.5 inches and about 2 inches below the opposite open end. In a preferred embodiment, the dividers 130 extend from between about 3 inches and about 5 inches above the closed end at the bottom 4 of the primary bag 10 to a point between about 0.75 inches and about 1.5 inches below the opposite open end. In a more preferred embodiment, the dividers 130 extend from about 4 inches above the closed end at the bottom 4 of the primary bag 10 to a point about 1 inch below the opposite open end. The dividers 130 may not extend to the bottom 4 or closed end of the bag 10 in order to allow a stiff bottom insert to be inserted into the primary bag 10. The dividers 130 may be sewn to an inner surface of the sidewalls 2, 6, 16 of the primary bag 10 using stitching 50, 52 or other attaching mechanisms. In some embodiments, a first end of one or more dividers 130 is interconnected to the inner surface of the side panel 2 via stitching 50 and a second end of the one or more dividers 130 is interconnected to the inner surface of the opposite side panel 2 via stitching 50. The dividers 130 may extend downward and upward only as far as the stitching 50 extends. Thus, in the embodiment shown, the dividers 130 may extend from a height above the bottom panel 4 to a distance below the upper edged of the side panels 2. The distance below the upper edge may be equal to the height of the stiffening hem 18. Additionally, a first end of one or more dividers 130 is interconnected to the inner surface of the front panel 6 via stitching 52 and a second end of the one or more dividers 130 is interconnected to the inner surface of the back panel 16 via stitching 52 such that these dividers are substantially perpendicular to the one or more dividers 130 interconnected to the two side panels 2. The dividers 130 may extend downward and upward only as far as the stitching 52 extends. Thus, in the embodiment shown, the dividers 130 may extend from a height above the bottom panel 4 to a distance below the upper edges of the front panel 6 and back panel 16. The distance below the upper edge may be equal to the height of the stiffening hem 18. Accordingly, the divider stitching 50, 52 may stop at the top fold stitching line 70.

[0054] In various embodiments, channel walls extend parallel to the front panel 6 and are interconnected at a first end to an inner surface of a first side panel 2 and interconnected at a second end to an inner surface of a second side panel 2 to form a channel 58 running substantially parallel to the front panel 6. Alternatively, the channel may run parallel to the side panels 2. Further, some dividers 130 are interconnected on a first end to the front panel 6 and interconnected on a second end to a first channel wall. Other dividers 130 are interconnected on a first end to the back panel 16 and interconnected on a second end to a second channel wall.

[0055] In various embodiments, the dividers 130 are positioned such that the walls of the dividers 130 are parallel to the sidewalls 2, 6, 16 of the primary bag 10. Thus, the compartments 14 formed by the dividers 130 are vertical and extend in a direction parallel to the vertical axis of the primary bag 10. In one embodiment, the dividers 130 are permanently attached to the sides 2, front 6, back 16, and/or bottom 4 of the primary bag 10. In another embodiment, the dividers 130 are removable. The dividers 130 may slide into grooves in the primary bag 10, may be sized to fit in the primary bag 10 without grooves or other positioning mechanism, or may snap, clip, or zip into the primary bag 10. In one embodiments, the dividers 130 are fixed on one side (e.g., secured to the inner surface of the front 6 of the bag 10) and detachable on the opposite side (e.g., detachable from the inner surface of the back 16 of the main bag 10). In other embodiments, some dividers 130 are fixed to the primary bag 10 while other dividers 130 are not fixed to the primary bag 10. For example, if divider n (where n is the divider number) is fixed, then divider n+1 is not fixed to the primary bag 10.

[0056] In yet another embodiment, the dividers 130 may be positioned to form compartments 14 or may be folded or collapsed and slid to the side such that the primary bag 10 has one large open compartment and so that the primary bag 10 may be folded flat for storage. The dividers 130 may add support or structure to the primary bag 10 primary bag 10 to keep the bag 10 open.

[0057] In one embodiment, the dividers 130 form compartments 14 that are all one size and shape. In another embodiment, the dividers 130 form compartments 14 that are different shapes and sizes to accommodate differently sized shopping bags or other items.

[0058] In some embodiments, the dividers 130 may be cardboard, plastic, or another sturdy material. Alternatively, the dividers 130 may be rods or poles. In one embodiment, the rods or poles comprise many differently sized rods that telescope open to an extended position and collapse into one another to allow for folding and storage. Alternatively, the rods or poles may have rope or string within their centers to disassemble into multiple small pieces and easily reassemble into dividers 130 without losing the small pieces. Thus, the rods or poles with string may work much like a tent pole. In one embodiment, the tent pole-like rods may pop or spring open to expand the bag 10 into an open position. Then a user could detach or disassemble the tent pole-like rods to fold the primary bag 10 and lay it flat for storage. Tent poles are known and any such pole could be used.

[0059] In one embodiment, the system may comprise a divider structure 130 that can be inserted into any reusable bag to create the bag storage system 1. A user would only have to purchase the divider 130 and insert it into a bag sized to accommodate the divider 130. The divider 130 may fold flat for shipping and storage. Alternatively, the insert may have a center piece and pockets on each side of the insert. Accordingly, the user could put the insert into a reusable bag and store other reusable bags within the pockets. Further, the system could include two inserts with pockets on one side of each insert such that a user would put one insert into a reusable bag along one side of the bag and put the other insert into the bag along another side of the bag. The inserts may be positioned parallel to one another or perpendicular to one another depending on sizing and preference.

[0060] In a further embodiment, straps (such as elastic bands) may be sewn into the sidewalls of the primary bag 10. These straps (not shown) may be on the inside of the primary bag 10 or the outside of the primary bag 10. The straps are stretchy and can hold one or more rolled up secondary bags 20, 30, 40.

[0061] In some embodiments (not shown), an interior, flexible bag of substantially the same size and shape as the primary bag 10 (or maybe slightly smaller) is inserted and secured into the hollow interior of the primary bag 10 to reinforce the primary bag 10 and to form four to twelve elongated storage compartments 14. The interior bag is stitched or glued to the primary bag 10 at four to eight equally-spaced seams, which extend axially between the bottom 4 of the primary bag 10 and the open end of the primary bag 10. The seams are peripherally positioned at each of the four vertical corners and midway or a third of the way along each of the sidewalls 2, 6, 16. In addition to forming the storage compartments between the interior bag and the primary bag 10, the seams secure together multiple layers of material and serve as stiffening elements that give the sidewalls sufficient stiffness such that primary bag 10 can stand by itself with the open end open to receive shopping items or secondary reusable bags 20, 30, 40. Additionally, the center of the interior bag may be empty so that shopping items, purses, phones, wallets, toys, games, tablets, keys, gloves, scarves, hats, sunglasses, etc., may be contained within the bag, while secondary reusable bags 20, 30, 40 are retained in the compartments between the interior bag and the primary bag 10. Alternatively, a divider may be placed or secured (either permanently or removably) into the center compartment of the interior bag for the storage of additional bags or to keep shopping items or personal items separate from one another.

[0062] In various embodiments, the primary bag 10 may be made of canvas, polyester, nylon, plastic, non-woven polypropylene, woven synthetic materials, mesh, or any other material. In one embodiment, the primary bag 10 is formed from a sturdy fabric defining a bottom 4 (also called a base herein) and sidewalls 6, 2, 16. In some embodiments, the primary bag 10 is comprised of about 80 gsm to about 150 gsm non-woven polypropylene. In one embodiment, the primary bag 10 is comprised of a non-woven laminate material that is between about 75 gsm and about 195 gsm. Further, the material may be a matte laminate material. In a preferred embodiment, the primary bag 10 is comprised of a non-woven laminate material that is between about 95 gsm and about 175 gsm. In a more preferred embodiment, the primary bag 10 is comprised of a non-woven laminate material that is between about 125 gsm and about 165 gsm. In a most preferred embodiment, the primary bag 10 is comprised of a non-woven laminate material that is about 150 gsm.

[0063] In various embodiments, the bottom 4 of the primary bag 10 may be a thicker or stronger material than the rest of the primary bag 10. This is so that the bag 10 can support and hold heavy items like beverages, liquids, bottles, and the like. In one embodiment, a sturdy bottom piece (also called a bottom insert herein) is removably inserted into the bottom 4 of the bag 10 and is positioned flat against the bottom 4 of the bag 10. This additional piece may be the same shape and size as the bottom 4 of the bag 10 and may add structure or support. The bottom insert, in some embodiments, is plastic, cardboard, metal, Styrofoam, or other rigid material. Additionally, the bottom insert may fold up against a sidewall 2, 6, 16 of the primary bag 10 such that the bag 10 can be folded and stored in a flat position. Alternatively, the bottom insert may be removable to allow the primary bag 10 to be stored in a flat position or to allow the bag 10 to be folded or rolled up for storage.

[0064] In some embodiments, the primary bag 10 may have one or more closure mechanisms to keep the primary bag 10 closed such that items within the bag 10 will not fall out. Thus, the primary bag 10 may have a closure mechanism that uses straps, flaps, snaps, hook and loop material, buttons, zippers, or claps. In one embodiment, the primary bag 10 can have a cover portion interconnected to one sidewall of the bag 10. The cover portion can have a snap, hook and loop material, or a button that engages with a snap, hook and loop material, or button slot on an opposite sidewall of the bag 10.

[0065] In one embodiment, the main bag 10 is an insulated bag. Insulated bags are known in the art and any known insulated bag may be used. Alternatively, the primary bag 10 may lined for increase structure, support, and/or insulation. In one embodiment, the insulation is at least one of spunlace foil and foam.

[0066] In one embodiment, the primary bag 10 may be a different size. For example, the primary bag 10 may only have four compartments 14 and a channel 58 that is interconnected on one end to the front portion 6 of the main bag 10 and interconnected on a second end to the back portion 16 of the main bag 10. Thus, the channel 58 runs from the front of the bag 10 to the bag of the bag 10, rather than from side-to-side as shown in FIGS. 2 and 4-5.

[0067] FIG. 3 shows one embodiment of the interconnection device 64 for securing the primary bag 10 to a shopping cart, a trunk of a car, and/or an interior of a car. Additionally, the interconnection device can secure the handles 12 to one another for storage. In one embodiment, the interconnection device 64 is interconnected to at least one handle 12 and comprises a strap 300, a male snap element 302, and a female snap element 304. In alternate embodiments, the interconnection device may comprise hook and loop material or other fasteners rather than the male snap element 302 and the female snap element 304. In the embodiment shown, the upper surface of the male snap element 302 is shown and is positioned proximate to a second end of the strap 300. Further, the bottom surface of the female snap element 304 is shown proximate to a first end of the strap 300. Therefore, the second end of the strap 300 is looped around such that the bottom surface of the male snap element 302 (on the back of the strap 300, not shown) can be snapped into the bottom surface of the female snap element 304 (on the front of the strap 300, shown). The snap elements 302, 304 may be metal or plastic material.

[0068] The strap 300 is interconnected to a handle 12 by folding the first end at the fold line 306, placing the handle 12 width between the folded first end and the portion of the strap with the female snap element 304, and sewing or securing the first end of the strap 300 to a portion of the strap 300 proximate to the stitching line 308. The strap 300 can be secured using stitching, glue, clips, staples, and other securing mechanisms known in the art. Further, in one embodiment, the interconnection device 64 can slide along the handle 12, while in other embodiments, the interconnection device 64 is attached to a portion of the handle 12. The interconnection device 64 may be attached to a center portion of the handle 12 in various embodiments. The strap 300 can be made of a woven nylon material in one embodiment, or other woven material in other embodiments. Woven nylon tends to fray less than other materials used in the art. In another embodiment, the strap is a non-woven polypropylene material. In further embodiments, the handles are comprised of any material known in the art.

[0069] In one embodiment, the length L5 of the strap 300 is between about 4 inches and about 12 inches. In a preferred embodiment, length L5 of the strap 300 is between about 6 inches and about 10 inches. In a more preferred embodiment, length L5 of the strap 300 is between about 7 inches and about 9 inches. In a most preferred embodiment, length L5 of the strap 300 is about 8 inches. In one embodiment, the width W5 of the strap 300 is between about 0.5 inches and about 1.5 inches. In a preferred embodiment, width W5 of the strap 300 is between about 0.75 inches and about 1.25 inches. In a more preferred embodiment, width W5 of the strap 300 is about 1.0 inch.

[0070] In one embodiment, the fold line 306 is a distance S1 of between about 0.75 inches and about 1.75 inches from the first end of the strap 300. In a preferred embodiment, the fold line 306 is a distance S1 of between about 1.0 inch and about 1.5 inches from the first end of the strap 300. In more preferred embodiment, the fold line 306 is a distance S1 of about 1.25 inches from the first end of the strap 300. In one embodiment, the stitching line 308 is a distance S3 of between about 1.5 inches and about 3.5 inches from the first end of the strap 300. In a preferred embodiment, the stitching line 308 is a distance S3 of between about 2.0 inches and about 3.0 inches from the first end of the strap 300. In more preferred embodiment, the stitching line 308 is a distance S3 of about 2.5 inches from the first end of the strap 300.

[0071] In one embodiment, the distance S2 between the stitching line 308 and the center of the male snap element 302 is between about 3 inches and about 7 inches. In a preferred embodiment, the distance S2 between the stitching line 308 and the center of the male snap element 302 is between about 4 inches and about 6 inches. In more preferred embodiment, the distance S2 between the stitching line 308 and the center of the male snap element 302 is about 5 inches. In one embodiment, the distance S4 between the second end of the strap 300 and the center of the male snap element 302 is between about 0.25 inches and about 1.0 inch. In a preferred embodiment, the distance S4 between the second end of the strap 300 and the center of the male snap element 302 is between about 0.4 inches and about 0.75 inches. In more preferred embodiment, the distance S4 between the second end of the strap 300 and the center of the male snap element 302 is about 0.5 inches.

[0072] FIG. 4 shows a rear perspective view of the primary bag 10 holding multiple secondary bags 20. The back panel 16 of the primary bag 10 can be seen in this view. Additionally, the divider stitching 52 is also visible on the back panel 16 of the bag 10. Here, two secondary bags 20 are rolled and stored in compartments 14 of the primary bag 10. In one embodiment, the rolled-up secondary bags 20 will stick out above the upper edge of the primary bag 10, which assists in pulling the secondary bags 20 out of the compartments 14 of the primary bag 10. The secondary bags 20 may stick out above the upper edge of the primary bag 10 about 1.0 inch. Additionally, having the dividers 130 stop a distance below the upper edge of the primary bag 10 further assists a user in pulling the secondary bag 20 out of the compartment 14 of the primary bag 10.

[0073] In use, a user may fill one or more compartments 14 within the primary bag 10 with reusable shopping bags 20. The reusable bags 20 may be rolled or folded and placed in the compartments 14. The secondary bag 20 may comprise snap closures, snaps, clips, magnets, or hook and loop material (e.g., Velcro) to keep the bag 20 in a rolled or folded configuration and so that the secondary bag 20 easily slides into the compartments 14 of the main bag 10.

[0074] FIG. 5 shows a top plan view of the primary bag 10. The primary bag 10 comprises a front panel 6, a first side panel 2, a second side panel 2, a back panel 16, a bottom panel 4, side piping 60, two handles 12, a pocket 8, dividers 130 forming compartments 14, two channel walls 132 forming a channel 58, and a closure mechanism having a first part 66 and a second part 68.

[0090] In some embodiments, the insulated bag 30 has a snap closure, Velcro, clip, snap, button, zipper, hook, belt, etc. to keep the bag 30 in a rolled-up or folded position. For example, the insulated bag 30 may have a flap 320 with a closure mechanism 322. The flap 320 can be positioned on a first side 32 of the bag 30 proximate the closed end of the bag 30. The closure mechanism 322 can be a snap or hook material that engages with another snap or loop material on a different side of the bag 30. Thus, the opposite side of the bag (i.e., the second side of the bag 30, not shown) may also have a flap with a closure mechanism positioned proximate the closed end of the bag 30. In other embodiments, the insulated bag 30 may not have mechanism to keep the insulated bag 30 in a folded position.

[0091] In some embodiments, the insulated bag 30 also includes a sturdy bottom insert. In one embodiment, the rolled up insulated bag 30 may be stored in one of the main bag's compartments 14. In an alternative embodiment, the folded insulated bag 30 is stored in a channel in the primary bag 10. The channel may be positioned between the compartments 14 of the primary bag 10 to store the folded or rolled up insulated bag 30 or any other personal items or shopping items. The channel may run the length of the primary bag 10 or the width of the primary bag 10 and may be positioned between the dividers 130. In another embodiment, the folded or rolled up insulated bag 30 is stored in an outer pocket 8 of the primary bag 10. In a further embodiment, the rolled-up or folded insulated bag 30 is stored in an internal pocket of the primary bag 30.

[0092] FIG. 8 shows a third embodiment of the secondary bag, where the secondary bag is a produce bag 40. Even though the produce bag 40 is called a produce bag 40, it may hold items other than produce. Thus, the bag 40 may be a mesh material or other breathable material that is well suited for holding produce. The produce bag 40 may be rolled up or folded and stored in the primary bag 10. Alternatively, two produce bags 40 may be rolled up and stored in a pocket 8 of the primary bag 10. In some embodiments, the produce bag 40 may have a snap, Velcro, clip, button, zipper, hook, belt, etc. to keep the bag in a rolled-up or folded position. In one embodiment, the rolled-up produce bag 40 may be stored in one of the primary bag's compartments 14. In another embodiment, the folded or rolled-up produce bag 40 may be stored in a pocket 8 of the main bag 10. The pocket may be an internal pocket or external pocket 8.

[0093] In some embodiments, the produce bag 40 comprises two pieces of material interconnected along an edge at the bottom 44 of the bag 40, along an edge of the first side 46 of the bag 40, and along an edge of the second side 48 of the bag 40.

[0095] FIG. 9 shows the reusable shopping bag system 1 secured to a shopping cart 90 via the interconnection device 64 on the primary bag 10. Although it is not shown, the reusable shopping bag system 1 can be secured to the inside or outside of the shopping cart 90 and may be secured to the cart's handle or the main basket of shopping cart 90. In various embodiments, the main primary bag 10 can have a mechanism 64 to temporarily secure the primary bag 10 filled with the secondary bags 20, 30, 40 and personal items to the user's shopping cart 90. Thus, the reusable shopping bag holder and system 1 may include a fastening assembly with a fastener capable of releasably securing the primary bag 10 to a shopping cart 90. In some embodiments, the reusable shopping bag holder and system 1 includes magnets to secure the primary bag 10 to a metal shopping cart. In one embodiment, the primary bag 10 has Velcro loops to secure the primary bag 10 to the user's shopping cart 90 while the user is shopping. In another embodiment, the primary bag 10 can have rigid hooks to secure the primary bag 10 to the user's shopping cart 90. In an additional embodiment, the rigid hooks may include hook material (i.e., the hook part of hook and loop material, or Velcro) on the outer surface of the rigid hooks such that the primary bag 10 may be secured to the back or trunk of a user's car by securing the hook material to a material surface of the user's vehicle. Alternatively, the handles 12 of the primary bag 10 may be tied to the user's shopping cart 90. Further, the reusable bag holder and system 1 may be secured to the inside of the shopping cart 90 or the outside of the shopping cart 90. These mechanisms may also be used to secure the primary bag 10 and system 1 to a specific location in the user's car or trunk.

[0096] FIG. 10 shows a method 100 of using the reusable shopping bag system. The method 100 includes providing a primary bag with a plurality of compartments and possibly a pocket and providing a plurality of secondary bags. The plurality of secondary bags may include reusable shopping bags, insulated bags, and/or mesh bags. The method 100 also includes storing each secondary bag in either the pocket of the primary bag or a compartment in the primary bag. The method 100 further includes the step 102 of getting the reusable shopping bag system and taking the reusable shopping bag system to the store. The next step 106 is securing the reusable shopping bag system to a shopping cart and shopping. Once shopping is complete, or while shopping, the user unpacks the secondary bags in step 110. This step 110 includes removing a first secondary bag from the primary bag, removing a second secondary bag from the primary bag, and so on. After checking out, the user can fill the secondary bag, and possibly the primary bag, with purchased items in step 114. Step 114 includes opening the first secondary bag, filling the first secondary bag with one or more purchased items, opening the second secondary bag, filling the second secondary bag with one or more purchased items, and so on until all needed bags are filled. Then, in step 118 the user empties the bags and folds or rolls up the secondary bags. This step 118 includes removing the one or more items from the first secondary bag, rolling or folding the first secondary bag, removing the one or more items from the second secondary bag, rolling or folding the second secondary bag, and so on until all bags are emptied and all secondary bags are folded or rolled up. In step 122, the user places the secondary bags into the primary bag for storage. This step 122 includes placing the rolled up or folded first secondary bag in either the pocket of the primary bag or an inner compartment of the primary bag; placing the rolled up or folded second secondary bag in either the pocket of the primary bag or a compartment of the primary bag, and doing to same for all remaining secondary bags.

[0097] In various embodiments, the bags may be made of a flexible woven material, non-woven material, all natural material, biodegradable material, material made from plant fibers, bamboo, leather, canvas, synthetic material, polypropylene, polyethylene terephthalate (recycled or not), polyester, shammy material (i.e., chamois leather or wash-leather), or any other known material commonly used for reusable bags. The primary bag 10 and/or all bags 10, 20, 30, 40 may be made of a non-woven fabric with or without lamination.

[0098] In one embodiment, at least one secondary bag 20, 30, 40 is made of a shammy material such that when the system 1 is in a user's car and the user needs a towel or napkin, the user can use the shammy bag. After clean up, the user can wash the shammy bag in the washing machine.

[0099] In one embodiment, the bag 10, 20, 30, 40 may be made of different materials. For example, two sides and the bottom may be one material, while the two other sides are another material. Thus, two sides may be mesh to promote breathability or two sides may be clear to allow a user to view the contents of the bag 10, 20, 30, 40. Further, the bottom of the bag 10, 20, 30, 40 may be a different material to increase the strength of the bag.

[0100] In many embodiments, the materials of the bags are hypo-allergenic, non-toxic, and can withstand multiple uses such that the bags 10, 20, 30, 40 are reusable. In some embodiments, the primary bag 10 or all bags 10, 20, 30, 40 may be water repellant or have a coating/lining to repel moisture. This would allow a user to easily clean the bag 10, 20, 30, 40 by wiping it off with a towel or rag. In some embodiments, the lining may be slick, similar to Teflon or may be wax to repel moisture, dirt, germs, etc. Other embodiments may be hand-washable or machine-washable so users can clean the bag or bags. The bags may have either a glossy or a matte finish. In some embodiments, one or more bags 30 are insulated (e.g., have a lining or foil coating) and/or one or more bags 40 are mesh material.

[0101] In one embodiment, the primary bag 10 with compartments 14 to hold secondary bags 20, 30, 40 may be UV resistant, or include a UV-resistant coating on the exterior surface such that the primary bag 10 does not degrade due to excessive exposure to sunlight in the back of a user's car. The primary bag 10 with the UV-resistant coating or material would also protect the secondary bags 20, 30, 40 and would increase the lifetime of the system 1. Such a coating may be an elastomeric coating.

[0102] In one embodiment of the shopping bag storage system 1, the primary bag 10 and/or the secondary bags 20, 30, 40 have a lining or coating to prevent the buildup of germs, microrganisms, dirt, stains, grime, etc. In some embodiments, the bags may need to be composed of a material that is ultraviolet (“UV”), rot, microbial, and mold resistant. The bags may collect germs or other microorganisms from shopping carts, floors, trunks, stores, food, etc. Therefore, UV technology may be used to kill germs, mold, bacteria, etc. that may grow in or on the bags after use. In one embodiment, the primary bag 10 comprises a UV wand with a UV lamp, a power source (e.g., battery, plug, etc.), and connections to connect the UV lamp to the power source. The connections may include wires, hooks, screws, springs, chords, and other electrical or connection components. For example, a UV wand may be positioned along the top of a side of the primary bag 10. The user may turn the UV wand on when inserting secondary bags 20, 30, 40 into the primary bag 10 so that germs and microorganisms are killed and not further spread. The UV wand may only kill germs on surfaces that the UV light touches, therefore the user may turn the wand toward the outside of the primary bag 10 and wave an unrolled bag in front of the UV wand before rolling the secondary bag 20, 30, 40 and placing it in the primary bag 10.

[0103] In some embodiments, the bags 10, 20, 30, 40 may include particular surface textures (e.g., internally, externally, or both) that prevent undesired bacterial contamination of such surfaces. One embodiment will, therefore, include a surface generally known as Sharklet. Sharklet is the world's first technology to inhibit bacterial survival, growth, transfer and migration through pattern alone. The Sharklet surface is comprised of millions of tiny diamonds arranged in a distinct pattern that mimics the microbe-resistant properties of sharkskin. Sharklet is a simple, cost-effective solution for bacterial control.

[0104] In some embodiments, the bag may be composed of a self-healing material. One of the defining characteristics of living organisms is their inherent ability to repair physical damage. A growing trend in biomimicry is the creation of non-living structural materials that also have the capacity to heal themselves when cut, torn or cracked. Self-healing materials that can repair damage without external human intervention may give manufactured goods longer lifetimes and reduce the demand for raw materials, as well as improving the inherent safety of materials. Thus, a bag composed of a self-healing material can reduce tears, rips, spills, leakage, and contamination.

[0105] The bags 10, 20, 30, 40 may include designs, logos, screen printing, heat transfer prints, roller prints, offset prints, etc. The bags 10, 20, 30, 40 may come in various colors, designs, and sizes. In one embodiment, the main bag 10 may be one color or have one design while the secondary bags 20, 30, 40 may be another color or have other designs that are different from the main bag 10. Accordingly, all secondary bags 20, 30, 40 may look the same while the primary bag 10 may look different in order to distinguish the bags. In a further embodiment, the primary bag 10 may be one color or have a design/logo while the secondary bags 20, 30, 40 are color coded for the type of product it holds, for example, green for produce, blue for cold/frozen items, red for meat, yellow for poultry, etc. Color coding reduces the risk of cross contamination from meat, fish, produce, and the like. Additionally, the colors remind consumers of the type of product for which the bag is designed. For example, one secondary bag 20 may be light blue for carrying sea food; one secondary bag 40 may be green (and may even be mesh) for carrying produce; one secondary bag 20 may be yellow for carrying chicken or other meat; one secondary bag 30 may be purple or dark blue (and may be insulated) for carrying frozen or refrigerated items; one secondary bag 20 may be white for carrying bread and other baked goods; one secondary bag 20 may be brown for carrying alcohol or other bottles and beverages; and so on.

[0106] In one embodiment, the bags 10, 20, 30, 40 have colored trim. In some embodiments, the colored trim is the piping 60 shown in FIG. 2. The trim may be a different color or material than the rest of the bag 10, 20, 30, 40 and may be for style purposes and/or for additional support. The trim may have ribbons, mesh material, glitter, and the like for style purposes.

[0107] In some embodiments, the bags 10, 20, 30, 40 may have UPC tags, barcodes, SKUs, etc. The bags 10, 20, 30, 40 may also have hang tabs or other ways to identify the bags 10, 20, 30, 40.

[0108] In various embodiments, the bags 10, 20, 30, 40 may have grommets, snaps, zippers, etc. The primary bag 10 and/or the secondary bags 20, 30, 40 may have Velcro closures, zippers 366, tabs with snaps 64, 66, 68, 266, 268, snaps or buttons 302, 304, ribbons, or string 404 to close the bag 10, 20, 30, 40 and keep it closed. The closing mechanism 366, 404, 402, 266, 268, 66, 68 may be positioned at the top or open end of the bag 10, 20, 30, 40. The closing mechanisms are useful to prevent purchased items from falling out of the bag and they help to keep the secondary bags 20, 30, 40 constrained within the primary bag 10 when the system 1 is stored in a user's car, truck, bike, or other moving space. Furthermore, the closing mechanisms 366, 404, 402, 266, 268, 66, 68 may keep the secondary bags 20, 30, 40 rolled up tightly to allow the secondary bags 20, 30, 40 to be inserted into the main bag 10 with ease.

[0109] The primary bag 10, and the secondary bags 20, 30, 40 in some embodiments, may have snaps or clips to keep the bag in an open position in order to insert the rolled up secondary bags 20, 30, 40. The clips, snaps, or Velcro may be on tabs that secure one side of the bag to another side of the bag. Multiple (one or more) tabs with securing mechanisms may be positioned on the primary bag 10 to counteract the pull of the other tabs to keep the bag 10 open. These securing mechanisms may also secure the main bag 10 to a shopping cart 90 and/or secure the main bag 10 to a mounting device in a user's car. Thus, in one embodiment, the system 1 may include a mounting device that the user can put in his/her car in order to detachably interconnect the main bag 10 with the secondary bags 20, 30, 40 to the mounting device to keep the system 1 from moving around the user's car or trunk.

[0110] In some embodiments, the reusable shopping bag storage system 1 also reminds a user to remove the system 1 from the user's car or other vehicle before entering a store. Thus, the primary bag 10 may include a chip or other processor that communicates with the user's electronic device, for example, smart phone, tablet, smart watch, or vehicle infotainment system (e.g., car's audio an navigation system), etc. to remind the user to take the reusable shopping bag storage system into the store. The chip or processor in the reusable shopping bag storage system 1 either knows or determine the position or location of the reusable shopping bag storage system 1 or the chip or processor works in conjunction with an electronic device to determine the location of the reusable shopping bag storage system 1 relative to a store (e.g., grocery store). Thus, when the chip or processor and/or electronic device determine that the reusable shopping bag storage system 1 is proximate to a store (such as a grocery store or other shopping store), the electronic device notifies the user reminding the user to take the reusable shopping bag storage system 1 into the store. In one embodiment, different preferred stores and distances from the stores can be set in the chip or processor and/or the user's electronic device such that the user is only notified when he or she is within a set distance from a preferred store. The chip or processor and electronic device may also know if the reusable shopping bag storage system 1 is stationary indicating that the user has parked his or her car and will be entering a store.

[0111] Further, the system 1 may also include an application (i.e., app) for an electronic device (for example, smart phone, tablet, smart watch, or vehicle infotainment system) that communicates with the chip or processor. Accordingly, the application can remind the user to take the reusable shopping bag storage system 1 into the store with the user. Further, the electronic device, phone, tablet, smart watch, or vehicle infotainment system comprises a processor, memory, an input device, a display to display content, electrical circuits, and a power source (which can be a battery). The electronic device and/or the reusable shopping bag storage system 1 can further include data storage, software, a user interface, an input device, an output device, a communication network, such as Bluetooth or WiFi, and/or a communication interface for communicating with the chip or processor on the system 1, another computing device, and/or the communication network. In further embodiments, the processor can include any processor capable of performing instructions encoded in software or firmware. Further, the processor can be provided to execute instructions contained within the memory and/or data storage. The processor can comprise a controller or application specific integrated circuit (ASIC) having or capable of performing instructions encoded in logic circuits. The memory may be used to store programs or data, including data comprising content. As examples, the memory may comprise RAM, SDRAM, or other solid state memory. Alternatively or in addition, data storage may be provided. The data storage may generally include storage for programs and data.

[0112] Additionally, in some embodiments, the reusable shopping bag storage system 1 can receive relevant data (e.g., position or location of the system 1) from the user's electronic device using near field communication (NFC) or other wireless proximity sensors between the system 1 and electronic device.

[0113] In one embodiment, the position of the reusable shopping bag storage system 1 can be recorded using a computing device, such as a computer, tablet, smart phone, or other electronic device, and digital memory for subsequent use of the data in further operations. The electronic device can further include data storage, software, a user interface, an input device, an output device, a communication network, such as Bluetooth or WiFi, and/or a communication interface for communicating with another computing device and/or the communication network. In another embodiment, the reusable shopping bag storage system's 1 position is recorded using a device or mechanism that comprises a processor, memory, an input device, a display to display content, and a power source (which can be a battery). Alternatively, other positioning devices and/or computing devices known in the art can be used.
