[0018] FIG. 1 includes a plan view of a carton blank 1 used to form a carton 3 (FIGS. 2 and 3 ) of a first embodiment of the disclosure. FIG. 1 shows an exterior or printed side 4 of the blank 1. The carton 3 can be used to hold a food product (not shown), such as a fast-food item (e.g., sandwich, French fries, burrito, scrambled eggs, etc.). The carton 3 with food product can be placed in a microwave oven (not shown) to heat and/or cook the food products, or the fully cooked and/or heated food product can be placed in the carton for service to a customer for consumption. The carton 3 includes a tray 7 that is sized to hold the food product, and a lid 11 foldably connected to the tray 7 at a hinge 15. The hinge 15 has features to facilitate movement of the lid 11 between the closed position (FIG. 2 ) and the open position (FIG. 3 ), and vice versa.
[0019] The carton 3 may have an element (not shown) for use in cooking, heating, browning, and/or shielding (e.g., a microwave energy interactive element such as, but not limited to, a susceptor) mounted to one or more surfaces of the tray 7 and/or the lid 11. Alternatively, or in addition, the carton 3 can also include a window in one or more of the panels of the tray 7 and/or the lid 11. For example, a window could include an opening defined a top panel of the tray 7 and a transparent or translucent liner material covering the opening. It is understood that the microwave energy interactive elements or features and the window may be omitted from the carton 3 without departing from the disclosure. In this specification, the terms “lower,” “bottom,” “upper,” and “top” indicate orientations determined in relation to fully erected and upright packages.
[0020] As shown in FIG. 1 , the carton blank 1 has a longitudinal axis L1 and a lateral axis L2. The blank 1 includes a first or tray portion 17 for forming the tray 7 and a second or lid portion 19 for forming the lid 11. The tray portion 17 includes a bottom panel 21 foldably connected to a first side panel 23 at a lateral fold line 25. A second side panel 29 is foldably connected to the bottom panel 21 at a lateral fold line 31. In the illustrated embodiment, the bottom panel 21 includes two end flaps 35, 37 foldably connected to opposite ends of the bottom panel 21. The first side panel 23 has two end flaps 39, 41 foldably connected to opposite ends of the first side panel. The second side panel 29 has two end flaps 45, 47 foldably connected to opposite ends of the second side panel. In the illustrated embodiment, the end flaps 35, 37 include locking projections 55, 57.
[0021] The end flaps 35, 39, 45 extend along a first marginal area of the tray portion 17 and are foldably connected at a first longitudinal fold line 51. The end flaps 37, 41, 47 extend along a second marginal area of the tray portion 17, and are foldably connected at a second longitudinal fold line 53. The longitudinal fold lines 51, 53 may be, for example, substantially straight, or offset at one or more locations to account for blank thickness or for other factors. Additionally, the ends of the longitudinal fold lines 51, 53 can be at least slightly oblique to help in positioning the sides and ends of the carton 3 to be oblique with respect to the top and bottom of the carton. The features that form the tray portion 17 and the tray 7 could be otherwise shaped, arranged, configured, and/or omitted without departing from the disclosure.
[0022] In the illustrated embodiment, the lid portion 19 is shaped generally similar to the tray portion 17 and includes a top panel 61 foldably connected to a first side panel 63 at a lateral fold line 65 and a second side panel 67 at a lateral fold line 69. The top panel 61 includes two end panels 73, 83 foldably connected to opposite ends of the top panel 61. The first side panel 63 has two end flaps 75, 85 foldably connected to opposite ends of the first side panel. The end panels 73, 83 include respective end flaps 77, 87 foldably connected to the respective end panels 73, 83 adjacent opposite ends of the second side panel 67. In the illustrated embodiment, the end flaps 77, 87 include locking projections 56, 58 for engaging the respective locking projections 55, 57 in the tray 7 when the carton 3 is in the closed configuration (FIG. 2 ).
[0023] The end panel 73 and the end flaps 75, 77 extend along a first marginal area of the lid portion 19. The end panel 83 and the end flaps 85, 87 extend along a second marginal area of the lid portion 19. The end panels 73, 83 are foldably connected to the top panel 61 at a respective first longitudinal fold line 91 and second longitudinal fold line 93. The end flaps 75, 85 are foldably connected to the first side panel 63 at respective ends of the respective first longitudinal fold line 91 and second longitudinal fold line 93. The end flaps 77, 87 are foldably connected to the respective end panels 73, 83 along respective ends of the lateral fold line 69. As with the tray portion 17, the longitudinal fold lines 91, 93 can have portions that are offset, oblique, and/or spaced apart from other portions of the fold line. The features that form the lid portion 19 and the lid 11 could be otherwise shaped, arranged, configured, and/or omitted without departing from the disclosure.
[0024] As shown in FIG. 1 , the features that form the hinge 15 extend in or between the side panel 23 (e.g., tray hinge side panel 23) and the side panel 63 (e.g., lid hinge side panel 63). The features that form the hinge 15 can include two spaced-apart, lateral hinge fold lines 97, 99 at respective ends of the hinge side panels 23, 63. The hinge fold lines 97, 99 foldably connect respective portions of the tray hinge side panel 23 of the tray portion 17 to respective portions of the lid hinge side panel 63 of the lid portion 19. The features that form the hinge 15 can include a cut 121 that extends generally between the hinge fold lines 97, 99, oblique fold lines or creases 103, 105, 107, 109 in the lid hinge side panel 63, and oblique fold lines or creases 115, 117 and a lateral fold line or crease 119 in the tray hinge side panel 23. The tray hinge side panel 23 can include a debossed portion 111 that is at least partially defined by the oblique creases 115, 117 and the lateral crease 119, which extends between respective ends of the oblique creases 115, 117. The debossed portion 111 is pressed inwardly from the exterior surface 4 of the blank 1. In one embodiment, the portion of the side panel 63 defined by the oblique fold lines 103, 109 and the cut 121 can be an embossed portion 151 of the hinge 15. The embossed portion 151 can be pressed outwardly relative to the remaining portions of the side panel 63.
[0025] As shown in FIGS. 1 and 1A , the cut 121 can include two short, oblique end portions 125, 127 extending from respective ends of a lateral central portion 129 of the cut 121. The end portion 125 can extend from a junction of the oblique fold line 103 and the hinge fold line 97, and the end portion 127 can extend from a junction of the oblique fold line 109 and the hinge fold line 99. In the illustrated embodiment, the hinge fold lines 97, 99 are generally aligned with a hinge axis A1, and the central portion 129 is spaced apart from and generally parallel to the hinge axis A1 and the hinge fold lines 97, 99. The central portion 129 can be spaced apart from the hinge axis A1 by a distance D1 (FIG. 1A ), which, according to one exemplary embodiment, can be approximately 1/16 to ⅛ of an inch. The central portion 129 also can be spaced apart from and generally parallel with the lateral crease 119 forming the debossed portion 111. In one exemplary embodiment, the lateral portion 129 of the cut 121 is spaced apart from the lateral fold line 119 by approximately ⅛ of an inch. The central portion 129 of the cut 121 and/or the lateral fold line 119 could be otherwise located without departing from the disclosure.
[0026] As shown in FIG. 1 , the oblique creases 105, 107 can extend from a midpoint of the central portion 129 of the cut 121 to the lateral fold line 65, and the oblique creases 103, 109 can extend from the respective end portions 125, 127 of the cut 121 to the lateral fold line 65. The oblique creases 103, 105, 107, 109 can help reinforce the lid hinge side panel 63. Similarly, the oblique creases 115, 117 and the lateral crease 119 can help reinforce the tray hinge side panel 23. The blank 1 could have other features for forming the hinge 15 or the features shown could be otherwise shaped, arranged, configured, and/or omitted without departing from the disclosure.
[0027] In one exemplary embodiment, the carton 3 is formed by forming the tray portion 17 of the blank 1 into the tray 7 and forming the lid portion 19 of the blank into the lid 11. In one exemplary method, the tray 7 is formed by folding the side panels 23, 29 and the end flaps 35, 37 relative to the bottom panel 21. The end flaps 39, 45 are inwardly folded and overlapped with the end flap 35 to form respective reinforced corners 131, 133 of the tray 7. The end flaps 41, 47 are overlapped with the end flap 37 to form respective reinforced corners 135, 137 of the tray 7. In one embodiment, the end flaps can be glued to the respective end flaps 35, 37. The tray 7 could be formed by other forming steps without departing from the disclosure.
[0028] The lid 11 is formed in a similar manner as the tray 7. In one exemplary method, the lid 11 is formed by folding the side panels 63, 67 and the end panels 73, 83 relative to the top panel 61. The end flaps 75, 85 are inwardly folded and overlapped with the respective end panels 73, 83 to form respective reinforced corners 141, 145 of the lid 11. The end flaps 77, 87 are inwardly folded and overlapped with the side panel 67 to form respective reinforced corners 143, 147 of the lid 11. The lid 11 could be formed by other forming steps without departing from the disclosure.
[0029] A food product or other product can be placed on the bottom wall 21 of the tray 7 and the lid 11 can be folded in the direction of arrow A1 (FIG. 3 ) to close the carton 3 (FIG. 2 ). The locking features 55, 57 can engage the respective locking features 56, 58 when the carton 3 is in the closed configuration to help retain the carton in the closed configuration. The hinge 15 is configured to prevent buckling of the material in the side panels 23, 63 and to facilitate movement of the lid 11 from the open position (FIG. 3 ) to the closed position (FIG. 2 ) and from the closed position to the open position. As the lid 11 is folded relative to the tray 7, the lid hinge side panel 63 pivots relative to the tray hinge side panel 23 along the hinge fold lines 97, 99. In the illustrated embodiment, the cut 121 forms a protrusion extending from the lid hinge side panel 63 and a corresponding recess in the edge of the tray hinge side panel 23. As the lid hinge side panel 63 pivots relative to the tray hinge side panel 23, the protrusion can pivot past the recess, which provides room to help reduce interference between the side panels 23, 63. Accordingly, the cut 121 can help reduce buckling of the side panels 23, 63. The debossed portion 111 of the side panel 23 is pressed inwardly relative to the rest of the side panel 23 and helps to further offset the respective edges of the side panels 23, 63 formed at the lateral portion 129 of the cut 121 and reduce or eliminate any interference that may otherwise occur between the hinge side panels when the lid 11 is moved relative to the tray 7. Additionally, the embossed portion 151 of the lid 7 can be pressed outwardly relative to the remaining portions of the side panel 63 to further enhance the nonbinding or anti-buckling features of the hinge 15. The hinge 15 and the carton 3 could be otherwise shaped, arranged, and/or configured without departing from the disclosure.
[0030] FIGS. 4-6 illustrate a blank 201 and carton 203 according to a second embodiment similar to the carton 3 and blank 1 of the first embodiment. Accordingly, like or similar features are indicated with like or similar reference numbers between the two embodiments. The second embodiment is generally similar to the first embodiment, except for variations noted and variations that will be apparent to one of ordinary skill in the art. The carton 203 has a tray 207, a lid 211, and a hinge 215 that foldably connects the lid and the tray. The hinge 215 is formed from features in the blank 201 including lateral hinge fold lines 297, 299 that foldably connect respective hinge side panels 223, 263 of the tray portion 217 and the lid portion 219 of the blank 201. The hinge fold lines 297, 299 can be generally aligned with a hinge axis A2 (FIG. 4A ). As shown in FIGS. 4 and 4A , the hinge 215 includes a cut 321 extending between the hinge fold lines 297, 299. The cut 321 can include two end portions 325, 327 and a lateral central portion 329 extending between the end portions 325, 327. The end portion 325 can extend from a junction of the oblique crease 315 and the hinge fold line 297, and the end portion 327 can extend from a junction of the oblique crease 317 and the hinge fold line 299. The central portion 329 of the cut 321 can be generally parallel to and offset from the hinge axis A2 (FIG. 4A ). The central portion 329 can be spaced apart from the hinge axis A2 by a distance D2 (FIG. 4A ), which, according to one exemplary embodiment, can be approximately 1/16 to ⅛ of an inch. The cut line 321 and the axis A2 could be otherwise shaped, arranged, configured and/or omitted without departing from the scope of the disclosure.
[0031] In the embodiment of FIGS. 4-6 , the side panel 223 of the tray portion 217 has a debossed area 311 that is pressed inwardly from the exterior surface 204 of the blank 201. The debossed area 311 is defined by the oblique creases 315, 317 in the tray hinge side panel 223 and the cut 321. The creases 315, 317 can help reinforce the tray hinge side panel 223. The hinge 215 could be otherwise shaped, arranged, and/or configured without departing from the scope of the disclosure.
[0032] The hinge 215 functions in a similar manner as the hinge 15 of the first embodiment. The cut 321 forms a protrusion extending from the tray hinge side panel 223 and a corresponding recess in the edge of the lid hinge side panel 263. As the lid hinge side panel 263 pivots relative to the tray hinge side panel 223, the recess can pivot past the protrusion, and the recess provides room to help reduce interference between the side panels 223, 263. The debossed area 311 is pressed inwardly from the remaining portions of the side panel 223 so that the edge of the side panel 223 formed at the cut line 321 is offset from the edge of the side panel 263 formed at the cut line 321. In this manner, the hinge 215 facilitates movement of the lid 211 while helping to reduce or eliminate buckling or interference of the material in the side panels 223, 263.
[0033] The blanks according to the present disclosure can be, for example, formed from coated paperboard and similar materials. For example, the interior and/or exterior sides of the blank can be coated with a clay coating. The clay coating may then be printed over with product, advertising, price coding, and other information or images. The blank may then be coated with a varnish to protect any information printed on the blank. The blank may also be coated with, for example, a moisture barrier layer, on either or both sides of the blank. In accordance with the above-described embodiments, the blank may be constructed of paperboard of a caliper such that it is heavier and more rigid than ordinary paper. The blank can also be constructed of other materials, such as cardboard, hard paper, or any other material having properties suitable for enabling the carton to function at least generally as described herein. The blank can also be laminated or coated with one or more sheet-like materials at selected panels or panel sections.
[0034] In accordance with the above-described embodiments of the present disclosure, a fold line can be any substantially linear, although not necessarily straight, form of weakening that facilitates folding therealong. More specifically, but not for the purpose of narrowing the scope of the present disclosure, fold lines may include: a score line, such as lines formed with a blunt scoring knife, or the like, which creates a crushed portion in the material along the desired line of weakness; a cut that extends partially into a material along the desired line of weakness, and/or a series of cuts that extend partially into and/or completely through the material along the desired line of weakness; and various combinations of these features.
[0035] As an example, a tear line can include: a slit that extends partially into the material along the desired line of weakness, and/or a series of spaced apart slits that extend partially into and/or completely through the material along the desired line of weakness, or various combinations of these features. As a more specific example, one type tear line is in the form of a series of spaced apart slits that extend completely through the material, with adjacent slits being spaced apart slightly so that a nick (e.g., a small somewhat bridging-like piece of the material) is defined between the adjacent slits for typically temporarily connecting the material across the tear line. The nicks are broken during tearing along the tear line. The nicks typically are a relatively small percentage of the tear line, and alternatively the nicks can be omitted from or torn in a tear line such that the tear line is a continuous cut line. That is, it is within the scope of the present disclosure for each of the tear lines to be replaced with a continuous slit, cut line, or the like. For example, a cut line can be a continuous slit or could be wider than a slit without departing from the present disclosure.
[0036] The above embodiments may be described as having one or more panels adhered together by glue during erection of the carton embodiments. The term “glue” is intended to encompass all manner of adhesives used to secure carton panels in place such as heat sealing, or any other manner than may or may not include glue, adhesive, or other bonding agent.
[0037] The foregoing description illustrates and describes various embodiments of the present disclosure. As various changes could be made in the above construction, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense. It will be understood by those skilled in the art that while the present disclosure has been discussed above with reference to exemplary embodiments, various additions, modifications and changes can be made thereto without departing from the spirit and scope of the disclosure.
