The primary product may comprise a single food item or a plurality of discrete portions. Where the container is used for food products such as frozen pizza, pasta or other Italian food, the secondary compartment may be used for condiment packets, napkins, eating utensils such as a plastic knife, fork or spoon, or other items. Condiment packets may contain, e.g. a topping such as a grated cheese product comprising Parmesan or Romano cheese or the like, a seasoning product such as garlic, oregano or crushed red pepper, a sauce such as tomato sauce or pesto sauce, or combinations of these or other products. Where the container is used for a frozen brownie, the secondary compartment may be used for a topping for the brownie such as a frosting or sprinkle packet, a powdered sugar packet, a whipped topping, or a serving of ice cream. Each of the illustrated containers has an open-ended lower compartment or sleeve and a closed-ended upper compartment as described in more detail below.
[0022] The container may be used as part of a system comprising one or more display cases, refrigerators, freezers, kiosks, or vending machines. Fig. 1 illustrates a system 10 comprising a food kiosk 12 that includes a refrigeration unit 14 containing plurality of containers 200 in accordance with a first embodiment of the invention, arranged in a plurality of stacks. The refrigeration unit may comprise a refrigerator and/or a freezer. The illustrated kiosk also includes a microwave oven 16 and a surface 18 for supporting one or more containers 200 after they have been removed from the refrigeration unit.
[0023] Referring now to FIG. 2, the container 200 is preferably made of paperboard material or another material having sufficient strength, stiffness, and durability to withstand handling in a vending machine and loads associated with commercial shipping, handling, etc. The container 200 is also preferably formed of a single, one-piece blank of the paperboard material. The container 200 includes dual compartment portions, specifically an open-ended lower portion 202 and a closed-ended upper portion 204. The open-ended lower portion 202 and the closed-ended upper portion 204 define a primary cavity or compartment 206 and a secondary cavity or compartment 208. The primary and secondary cavities are preferably of the same length and width. The volume of the primary cavity 206 is preferably larger than the volume of the secondary cavity 208, because the primary cavity and the secondary cavity are preferably configured to respectively store a product 210 (e.g., a relatively large food product, such as a single serving frozen pizza or brownie) contained in a tray 212 and smaller items related to the product (e.g., condiments, eating utensils, and/or napkins). The tray 212 is preferably microwavable.
[0024] The primary cavity 206 is defined by an intermediate panel 214, a bottom panel 216, and a plurality of side wall panels 218, 220 (two shown) extending between a top panel 222 and the bottom panel. In this embodiment provided, the bottom panel 216 is preferably substantially parallel to the top panel 222, and the intermediate panel 214 is attached between the top panel and the bottom panel and dimensioned according to a predefined length 224. One of the panels that defines the primary cavity 206, specifically the intermediate panel 214, has a predefined length 224. The primary cavity 206 includes opposite open ends 226, 228 to facilitate insertion and removal of the product 210. In this embodiment, the primary cavity 206 includes inclined end edges 230, 232, 234, 236 at the opposite open ends 226, 228 between the intermediate panel 214 and the bottom panel 216. The container is also of varying length in that it is of maximum length at least adjacent the intermediate panel 214, with the top panel and bottom panel being shorter than the intermediate panel.
[0025] In Fig. 2, the tray 212 and product 210 are partially removed from the primary cavity 206. The tray and product are normally contained within the primary cavity prior to sale of the product, and may also be contained within a wrapper such as a transparent plastic wrapper enclosing the entire container or only the tray and product.
[0026] The secondary cavity 208 is defined by the top panel 222, the intermediate panel 214, and upper portions of the side wall panels 218, 220.
Since the intermediate panel 214 is a shared surface between the primary cavity 206 and the secondary cavity 208, the length of the secondary cavity is the predefined length 224 of the primary cavity. The secondary cavity 208, unlike the primary cavity, includes opposite ends 238, 240 enclosed by closure walls 242, 244. The secondary cavity 208 also includes inclined end edges 246, 248, 250, 252 between the top panel 222 and the intermediate panel 214. Specifically, a first pair of inclined end edges 246, 248 is provided at one end 238, and another pair of inclined end edges 250, 252 at the opposite end 240.
Since the intermediate panel 214 is a shared surface between the primary cavity 206 and the secondary cavity 208, the length of the secondary cavity is the predefined length 224 of the primary cavity. The secondary cavity 208, unlike the primary cavity, includes opposite ends 238, 240 enclosed by closure walls 242, 244. The secondary cavity 208 also includes inclined end edges 246, 248, 250, 252 between the top panel 222 and the intermediate panel 214. Specifically, a first pair of inclined end edges 246, 248 is provided at one end 238, and another pair of inclined end edges 250, 252 at the opposite end 240.
[0027] To secure items inside the secondary cavity 208, each closure wall 242, 244 is configured to include a first flap 254, 256 dimensioned to substantially cover one of the opposite ends of the secondary cavity in a closed position and a second flap 258, 260 attached to the first flap and foldable at a crease line to be inserted at least partially into the secondary cavity in the closed position. Two side flaps 262, 264 are also included with the closure wall 242, and the two side flaps are inserted into the secondary cavity at the opposite end 242 of the secondary cavity 208.
On the opposite end 244, two side flaps 266, 268 are similarly included. As shown, the first flap 254, 256 substantially covers each of the opposite ends 242, 244 at an incline between the top panel 222 and the intermediate panel 214. Furthermore, in this specific embodiment, the first flap 254, 256 is attached at a crease line to the intermediate panel 214.
On the opposite end 244, two side flaps 266, 268 are similarly included. As shown, the first flap 254, 256 substantially covers each of the opposite ends 242, 244 at an incline between the top panel 222 and the intermediate panel 214. Furthermore, in this specific embodiment, the first flap 254, 256 is attached at a crease line to the intermediate panel 214.
[0028] The first flap 254, 256 and the second flap 258, 260 are preferably combined as a single piece end flap 270, 272 having a bottom edge (e.g., the first flap 254, 256) being joined to the intermediate panel 214 by a hinge or a crease line 274, 276. According to this embodiment, the end flaps 270, 272 are each pivotable about the hinge between an open and a closed position and is securely connected to the intermediate panel 214 along the hinge. The container formed of a single, one-piece blank of paperboard material preferably includes a perforated fold line at the hinge in the paperboard material. In addition, for easy access to items stored in the secondary cavity 208, the top panel 222 preferably includes a tearable opening defined by lines of weakness 280 with a tab 282 projected outwardly to enable access to the tearable opening.
[0029] Referring now to FIG. 3, the side wall panels 218, 220 include first, second, third, and fourth side wall panels 300, 302, 304, 306. The bottom panel 216 adjoins the first side wall panel 300 along one edge 308. The second side wall panel 302 adjoins the bottom panel along the opposite edge 310. The top panel 222 adjoins the third side wall panel 304 along one edge 312 that is attached at least partially to the second side wall 302, and on the other side 314, is attached to the first side wall panel 300. The intermediate panel 214 adjoins the fourth side wall panel 306 that is attached at least partially to the first side wall panel 300 at one side 316, while being attached to the second side wall panel 302 at the other side 318.
From the configuration of the attachment of the third side wall panel 304 to the second side wall panel 302 and the attachment of the fourth side wall panel 306 to the first side wall panel 300, the volume of the primary cavity and the secondary cavity are defined.
From the configuration of the attachment of the third side wall panel 304 to the second side wall panel 302 and the attachment of the fourth side wall panel 306 to the first side wall panel 300, the volume of the primary cavity and the secondary cavity are defined.
[0030] Because the closure walls 242, 244 are attached to the intermediate panel 214, the first flap 254, 256 covers the secondary cavity 208 from the intermediate panel 214 to the top panel 222.
[0031] Turning now to FIG. 4, a foldable blank 400 that can be used to form the container 200 of FIGS. 2 and 3 is shown. The foldable blank 400 is illustrated as a sheet of material, such as paperboard, defining the top panel 222 set off by fold lines 402, 404 to form the first and third side wall panels 300, 304, respectively.
The first side wall panel 300 further includes fold lines 406, 408 defining the side flaps 262, 266, and similarly, the third side wall panel 304 includes fold lines 410, 412 that define the side flaps 264, 268. The bottom panel 216 is joined to the first side wall panel 300 by fold line 414 at the one side 310 and the second side wall panel 302 by _g_ fold line 416 at the opposite side 308. Lastly, the intermediate panel 214 is joined respectively to the second side wall panel 302 and the fourth side wall panel 306 by fold lines 418, 420. At the intermediate panel 214, fold lines 422, 424 define the end flaps 270, 272. Specifically, at the end flaps 270, 272, the first flaps 254, 256 and the second flaps 258, 260 are defined by fold lines 426, 428. In constructing the container 200, adhesive or like material is disposed upon the second side wall panel 302 for attachment to the third side wall panel 304 and upon the fourth side wall panel 306 for attachment to the first side wall panel 300.
The first side wall panel 300 further includes fold lines 406, 408 defining the side flaps 262, 266, and similarly, the third side wall panel 304 includes fold lines 410, 412 that define the side flaps 264, 268. The bottom panel 216 is joined to the first side wall panel 300 by fold line 414 at the one side 310 and the second side wall panel 302 by _g_ fold line 416 at the opposite side 308. Lastly, the intermediate panel 214 is joined respectively to the second side wall panel 302 and the fourth side wall panel 306 by fold lines 418, 420. At the intermediate panel 214, fold lines 422, 424 define the end flaps 270, 272. Specifically, at the end flaps 270, 272, the first flaps 254, 256 and the second flaps 258, 260 are defined by fold lines 426, 428. In constructing the container 200, adhesive or like material is disposed upon the second side wall panel 302 for attachment to the third side wall panel 304 and upon the fourth side wall panel 306 for attachment to the first side wall panel 300.
[0032] Referring now to FIG. 5, a container 200 according to a second embodiment is shown. The container 200 according to the second embodiment includes essentially all the same elements of the first embodiment, which will be referenced with the same numerical notation, with the exception that closure walls 500, 502 are configured differently in this embodiment. Unlike the first embodiment shown in FIGS. 1 and 2, the closure walls 500, 502 are attached to the top panel 222. Specifically, the end flaps 504, 506 of closure walls 500, 502 are attached to the top panel 222, rather than on the intermediate panel 214. In particular, at the front and back end 242, 244 of the container 200, the end flap 504, 506 includes respectively a first flap 508, 510 folded at a crease line 512, 514 to form a second flap 516, 518. As a result of the configuration, the end flaps 504, 506 enclose the secondary cavity 208 downwardly at each side 242, 244, specifically with the second flap 516, 518 being inserted along the intermediate panel 214 into the secondary cavity.
[0033] Moreover, in this embodiment, side flaps 520, 522, 524, 526 at both ends 242, 244 of the container are shaped differently from the first embodiment to better fit the configuration of the end flaps 504, 506. Also, to accommodate easy opening of the end flaps 504, 506, the intermediate panel 214 includes cut openings 528, 530, specifically of a rounded shape shown as an example, at both ends 242, 244 of the container 200. This second embodiment may facilitate handling during production packaging.
[0034] Turing to FIG. 6, a foldable blank 400 used for forming the container of FIG. 5 is shown. Similar to the first embodiment, the top panel 222 is joined to the first and third side wall panel 300, 304 by fold lines 402, 404, and the bottom panel 216 is joined to the first side wall panel 300 and the second side wall panel 302 by fold lines 414, 416. The intermediate panel is also joined to the second side wall panel 302 and the fourth side wall panel 306 by fold lines 418, 420. Unlike the first embodiment, however, the top panel 222 further includes closure walls 500, 502, while the intermediate panel does not. In particular, fold lines 600, 602 of the top panel 222 define the end flaps 504, 506 of closure walls 500, 502, and fold lines 604, 606 in turn define the first and second flaps 508, 510, 516, 518. At the first side wall panel 300, the side flaps 520, 524 are defined by fold lines 608, 610, and similarly, the side flaps 522, 526 are defined at fold lines 612, 614 at the third side wall panel 304. The construction of the blank similarly is formed by applying adhesive between the second and third side wall panels 302, 304 and the first and fourth side wall panels 300, 306.
[0035] Referring now to FIG. 7, a container 200 according to a third embodiment is shown. The third embodiment includes essentially most of the features of the second embodiment, which will be referenced using the same numerical notations.
The difference, however, is that in the third embodiment, closure walls 700, 702 are configured differently from the closure walls 500, 502 of the second embodiment. In particular, instead of having incline edges 246, 248, 250, 252 at the secondary cavity 208, the closure walls 700, 702 include straight edges 704, 706 at the front end 238 of the secondary cavity 208 and straight edges 708, 710 of the opposite back end 240. In the third embodiment, end flaps 712, 714 respectively include first flaps 716, 718 and second flaps 720, 722 divided by a crease line or hinge 724, 726.
Corresponding side flaps 728, 730, 732, 734 are included in this embodiment, but the shape and/or size are arranged differently to accommodate the straight edges 708, 710. In this embodiment, the closure walls 700, 702 are attached to the top panel 222 and are folded downwardly to enclose the secondary cavity 208.
Moreover, in this particular embodiment, although the rounded openings 528, are not included to more clearly show the end flaps 704, 706, rounded openings can also be similarly included for easy access in this embodiment.
The difference, however, is that in the third embodiment, closure walls 700, 702 are configured differently from the closure walls 500, 502 of the second embodiment. In particular, instead of having incline edges 246, 248, 250, 252 at the secondary cavity 208, the closure walls 700, 702 include straight edges 704, 706 at the front end 238 of the secondary cavity 208 and straight edges 708, 710 of the opposite back end 240. In the third embodiment, end flaps 712, 714 respectively include first flaps 716, 718 and second flaps 720, 722 divided by a crease line or hinge 724, 726.
Corresponding side flaps 728, 730, 732, 734 are included in this embodiment, but the shape and/or size are arranged differently to accommodate the straight edges 708, 710. In this embodiment, the closure walls 700, 702 are attached to the top panel 222 and are folded downwardly to enclose the secondary cavity 208.
Moreover, in this particular embodiment, although the rounded openings 528, are not included to more clearly show the end flaps 704, 706, rounded openings can also be similarly included for easy access in this embodiment.
[0036] Turning now to FIG. 8, the foldable blank 400 used for forming the container 200 of FIG. 7 is shown. The present foldable blank 400 includes similar features to the blank shown in FIG. 6 with the exception of a different configuration of the closure wall 700, 702. Specifically, each end flap 508, 510 is joined to the top panel 222 by fold lines 800, 802, respectively. The end flaps 508, 510 are in turn divided by fold lines 804, 806 to create the first flaps 508, 510 and second flaps 516, 518. One of the differences lays here with these fold lines. To give the configuration the straight edges 704, 706, 708, 710, the fold lines are placed such that the first flaps 508, 510 are smaller in length than the second flaps 516, 518.
Accordingly, in order to accommodate the configuration of the straight edge arrangement, the side flaps 728, 732, 730, and 734 are divided by fold lines 808, 810, 812, 814 and arranged with the different sizes and/or shapes shown. Moreover, at the intermediate panel 214, the rounded openings 528, 520 have been optionally omitted in this embodiment.
