Container having tab identifiers and method for constructing the same

[0001] This invention relates generally to containers and, more particularly, to a container having tab identifiers and a method for constructing the container.

[0002] Containers are oftentimes used for packaging, storing and/or transporting a product, such as food. At least some known containers are clamshell type containers fashioned from a unitary blank of paperboard and are used by the fast food industry. These clamshell type containers are typically used by first placing a sandwich or other food product into a lower or tray portion of the clamshell container, closing an upper or lid portion of the container, and providing the container with the food to a consumer. The container is typically releasably latched and is thereafter unlatched by the consumer to gain access to the product.

[0003] In this type of container, as well as in other types of containers particularly adapted for the fast food industry, there exists a need to identify the food product stored within the container so the assembler of the food product and/or package may readily designate the contents of the container to thereby inform any intermediate server and/or the consumer of the contents. In some cases, a server will identify the product stored within the container by marking the container with a writing utensil or using an adhesive label. Such current product identifiers are difficult to use and/or routinely lack description.

[0004] In one aspect, a container for packaging a product is provided. The container includes a blank of sheet material including a first panel, and at least one tab identifier defined within the first panel and moveable with respect to the first panel. The at least one tab identifier is configured to cooperate with a flex member assembly defined at least partially within the first panel. The blank forms the container including a tray portion and a lid portion coupled along a fold line to the tray portion. The lid portion is moveable about the fold line with respect to the tray portion between an open configuration and a closed configuration. In the closed configuration, the tray portion and the lid portion define a volume for storing the product.

[0005] In another aspect, a container for packaging a product is provided. The container includes a tray portion and a lid portion movably coupled to the tray portion along a first fold line. The lid portion is moveable about the first fold line with respect to the tray portion between an open configuration and a closed configuration. In the closed configuration, the tray portion and the lid portion define a volume for storing the product. The container further includes a flex member assembly at least partially defined within a first panel of the lid portion. The flex member assembly includes a first member and an opposing second member defining a slot extending therebetween. The container further includes a tab identifier coupled to the lid portion. The tab identifier is moveable about a second fold line and positionable within the slot.

[0006] In a further aspect, a container for packaging a product is provided. The container includes a tray portion and a lid portion movably coupled to the tray portion along a first fold line. The lid portion is moveable about the first fold line with respect to the tray portion between an open configuration and a closed configuration. In the closed configuration, the tray portion and the lid portion define a volume for storing the product. The container further includes a tab identifier defined within a first panel of the lid portion and moveable about a fold line to provide an opening through which a portion of a second panel coupled to the first panel is visible.

[0007] In a further aspect, a method for identifying a product is provided. The method includes constructing a container having a tray portion and a lid portion coupled to the tray portion along a first fold line, a flex member assembly defined within the lid portion, and at least one tab identifier defined within the lid portion. The tab identifier is rotated from an initial position into a display position. The tab identifier is engaged within the flex member assembly at the display position.

Flex members 105, 106 maintain tab identifier 102 in a locked or display position. In one embodiment, flex members 105, 106 engage a surface of tab identifier 102 to support and/or align tab identifier 102 in the locked or display position. Moreover, flex members 105, 106 are configured to flex outwardly to release tab identifier 102 such that tab identifier 102 may be returned to an initial position generally coplanar with front end panel 66.

[0046] In one embodiment, a plurality of tab identifiers 102 are defined within lid portion 14. As shown in FIG. 1, adjacent tab identifiers 102 may abut one another in lid portion 14. In this embodiment, a first tab identifier 132 and second tab identifier 133 share a common side edge 135 and are coupled to first side panel 70 along collinear fold lines 136 and 137 at a top edge 138. Tab identifiers 132 and 133 extend between fold lines 136 and 137, respectively, and bottom edge 140 of first side panel 70. First tab identifier 132 and second tab identifier 133 are moveable or rotatable about top edge 138 independently. In one embodiment, when more than one abutting tab identifier is defined with lid portion 14, flex member assembly 104 includes a suitable number of corresponding and cooperating flex members 105, 106 and/or slots 130.

[0047] Blank 10 includes an interior surface 144 and an exterior surface 146. Hence, each tab identifier 102 includes an interior surface 144 and an exterior surface 146. In one embodiment, each tab identifier 102 includes indicia on interior surface 144 and/or exterior surface 146 to identify the contents within container 11. In a particular embodiment, indicia is printed onto interior surface 144 and exterior surface 146. In an alternative embodiment, indicia may be applied to interior surface 144 and/or exterior surface 146, such as by adhesively affixing a label to interior surface 144 and exterior surface 146, or by drawing or writing indicia onto interior surface 144 and/or exterior surface 146. It is apparent to those skilled in the art and guided by the teachings herein provided that indicia may be applied to the container by any suitable method known to those skilled in the art and guided by the teachings herein provided. Indicia enables a user to quickly assign one of a plurality of products to a single container. Indicia also stimulates visual awareness of a user. For example, a tab identifier 102 may indicate the type of sandwich in tray portion 12 and a different tab identifier may indicate the condiments placed on the sandwich. Moreover, positioning of indicia on interior surface 144 within container 11 enables a user to identify a product order (i.e., a product to be placed within the container), when container 11 is in an open configuration 149 and ready to be loaded, as shown in FIG. 2. Indicia on exterior surface 146 further enables a user to easily determine the contents of container 11 among a plurality of other like-kind containers when the container is in the closed configuration.

[0048] FIG. 3 is a perspective view of container 11 constructed from blank 10 shown in FIG. 1. More specifically, FIG. 3 shows container 11 in a constructed and closed configuration. Generally, the panels and the flaps of blank 10 are folded along respective fold lines towards interior surface 144 of blank 10. Side panels 24, 26 are folded along fold lines 32, 34 towards bottom panel 18. End panels 20, 22 are folded inwardly along fold lines 28, 30 towards bottom panel 18. Furthermore, flaps 36, 40 are affixed to interior surface 144 of side panel 24, and flaps 38, 42 are affixed to interior surface 144 of side panel 26 using a suitable adhesive material. It is apparent to those skilled in the art and guided by the teachings herein provided that any suitable material and/or mechanism may be used to affix portions of blank 10 together to form container 11.

[0049] Flaps 82 and 92 are folded along edges 86 and 93, respectively. Flaps 88 and 90 are folded along fold lines 89 and 91, respectively. The flaps are then affixed to the interior surface of the corresponding panel. Specifically, flaps 82 and 92 are affixed to front end panel 66. Flap 88 is affixed to interior surface 144 of panel 70. Flap 90 is affixed to interior surface 144 of panel 72. In one embodiment, container 11 is moveable to a closed configuration by folding tray portion 12 and lid portion 14 toward interior surface 144 along fold line 16.

[0050] In the closed configuration, as shown in FIG. 3, panel 66 overlaps panel 20 and side panels 70, 72 overlap side panels 24, 26, respectively. Front end panel 66 releasably couples to front end panel 20. In one embodiment, flange 99 engages tab 60, and flange 100 engages tab 61 to retain container 11 in the closed configuration. It is apparent to those skilled in the art and guided by the teachings herein provided that any suitable component and/or mechanism may be used to releasably couple lid portion 14 to tray portion 12 to retain container 11 in the closed configuration.

[0051] As shown in FIG. 3, tab identifier 102 is shown in an initial position 147. In use, tab identifier 102 is rotated or moved about fold line 122. Side edge 118 and side edge 120 are defined by perforated edges for facilitating moving or rotating tab identifier 102 about fold line 122. Tab identifier 102 is rotated towards interior surface 144 to engage corresponding flex member assembly 104 within top panel 64. In one embodiment, tab identifier 102 is positioned within slot 130 defined in flex member assembly 104 and retained in a display position 148 by flex members 105 and 106.

[0052] At least a portion of tab identifier 102 extends outwardly from top panel 64 such that indicia on tab identifier 102 is visible in display position 148. When tab identifier 102 is in display position 148, flex members 105, 106 extend outwardly from lid portion 14. In this embodiment, tab identifier 102 includes indicia positioned at or near bottom edge 116 on interior surface 144 and/or exterior surface 146 of tab identifier 102. In a particular embodiment, indicia is placed on interior surface 144 of lid portion 14 near corresponding tab identifier 102 such that the indicia corresponds with contents of container 11, as shown in FIG. 2. Indicia on interior surface 144 of tab identifier 102 is visible when container 11 is in the closed configuration. Additionally, indicia positioned on exterior surface 146 of tab identifier 102 is visible from the interior of container 11 when container 11 is in open configuration 149 and tab identifier 102 is in display position 148. This allows a user to identify the product to be placed within container 11 without viewing the exterior of container 11 when container 11 is in open configuration 149.

[0053] FIG. 4 is a top plan view of a blank of sheet material 200 for constructing a container 201, according to an alternative embodiment.
