DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0021] Reference will now be made to the drawings wherein like reference numerals identify similar structural features or aspects of the subject disclosure. For purposes of explanation and illustration, and not limitation, a view of an embodiment of a blank system for forming a container in accordance with the disclosure is shown in FIGS. 1 and 2, and is designated generally by reference character 10. Other embodiments of containers in accordance with the disclosure, or aspects thereof, are provided in FIGS. 2-24 as will be described. The systems and methods described herein can be used to provide containers with attached dividers.

[0022] The blank system 10, depicted in FIGS. 1 and 2, includes a main blank 100 including a plurality of panels 102, 104, 106, 108 foldably connected together across respective fold lines 146, 148, 150 to enclose an interior space 152 (not visible in FIG. 1, but see FIG. 9). The main blank 100 also includes upper flaps 110, 112, 114, 116 and lower flaps 118, 120, 122, 124 foldably connected to each of the panels 102, 104, 106, 108, respectively. The upper flaps 110, 112, 114, 116 are foldably connected to the panels 102, 104, 106, 108 across respective fold lines 128, 132, 136, 140. The lower flaps 118, 120, 122, 124 are foldably connected to the panels 102, 104, 106, 108 across respective fold lines 130, 134, 138, 142. Each of the upper 110, 112, 114, 116 and lower 118, 120, 122, 124 flaps can be of similar size and shape from its respective opposite flap attached to the same panel. The upper 110, 112, 114, 116 and lower 118, 120, 122, 124 flaps can also differ in size and shape from its respective opposite flap attached to the same panel. The main blank 100 also includes a tab 126 foldably connected across fold line 144 to one of the plurality of panels 102.

[0023] The blank system 10 includes a shelf blank 200 which includes a main shelf panel 202 and a pair of opposed side shelf flaps 204, 206 foldably connected to the main shelf panel across respective fold lines 203, 205.

[0024] With reference now to FIG. 5, the shelf blank 200 is positioned over the main blank 100 on top of one of the plurality of panels 104 and one of the opposed flaps 112. The outer portion of the side shelf flap 206 aligns with fold line 134 between panel 104 and flap 120, so that the flap 120 can later fold at fold line 134 without interference from the shelf blank 200. The shelf blank 200 can be adhered to the main blank 100. The main blank 100 and shelf blank 200 can be composed of a paperboard or cardboard material which can be corrugated paper material.

[0025] With reference now to FIGS. 6-9, the folding of the plurality of panels 102, 104, 106, 108 across fold lines 142, 144, 146, 148 so as to enclose the interior space 152 (depicted in FIG. 9) is depicted. FIG. 6 depicts the tab 126 folding across fold line 144. As depicted in FIG. 7, the panels 102, 104, 106, 108 fold in a manner that brings the panel 108 into contact with the tab 126. The tab 126 can be adhered to the panel 108. FIG. 8 depicts the container 154 in a partially erected state, with flaps 120, 124 closed to partially form the bottom 123 of the container 154. Also visible in FIG. 8 are portions 202, 204 of the shelf blank 200 connected to the main blank 100. FIG. 9 depicts the partially erected container 154 with flaps 118, 122 folded closed to complete the bottom 123 of the container 154. As depicted in FIG. 9, the side shelf flap 204 folds 90 across fold line 203 with respect to the main shelf panel 202.

[0026] With reference to FIG. 10, the container 154 is shown with the shelf 207 folded into so as to create a lower interior space 156 (depicted in FIG. 13) within the interior space 152. The shelf 207 is formed by the folding of each of the opposed side shelf flaps 204, 206 across fold lines 203, 205 to 90 with respect to the main shelf panel 202. The opposed side shelf flaps 204, 206 can fold simultaneously or sequentially. The opposed side shelf flaps 204, 206 can fold to an acute angle with respect to the main shelf panel 202 during an intermediate phase of the folding process.

[0027] With reference to FIGS. 11 and 12, the top 125 of the container 154 is shown being formed by the folding closure of flaps 110, 114 (FIG. 11) and the folding closure of flaps 112, 116 (FIG. 12). The closure of the flaps 110, 114, 112, 116 to create the top 125 of the container 154 also creates an upper interior space 158 within the interior space 152 of the container 154. FIG. 12 depicts the erected, closed container 154. The container 154, and the interior space 152 display a rectangular footprint.

[0028] FIG. 13 depicts the container 154 partially erected to display a cross-sectional view of the container 154. Visible in FIG. 13 is the erected shelf 207, dividing the interior space 152 into a lower interior space 156 and an upper interior space 158. The shelf 207 spans the length of the interior space 152 along a longitudinal axis, L (depicted in FIG. 5). The shelf 207 also spans the width of the interior space 152 along a lateral axis, W (depicted in FIG. 5). The erected shelf 207 receives structural support from the folded opposed side shelf flaps 204, 206. The main shelf panel 202 serves as the area on which product can be placed. The main shelf panel 202 is supported by the folded side shelf flaps 204, 206 is of sufficient rigidity and strength to limit the amount of bowing into the lower interior space 156 when a load is applied thereto. The shelf 207 maintains an air gap between the top of the product in the lower interior space 156 and the portion of the main shelf panel 202 facing the lower interior space 156. The shelf blank 200 can be composed of a corrugated paper material, where the corrugations can be aligned to provide structural support and integrity for the assembled shelf 207. The weight of product loaded into the upper interior space 158, should be adequately supported so that no part of the shelf 207 deflects into the lower interior space 156 to touch, or otherwise impact a product placed into the lower interior space 156.

[0029] Without limiting the intended scope of potential uses for the disclosed container 154, an exemplary product that can be loaded into the disclosed container 154 is a cake, other baked goods, or other foods. Baked goods are relatively fragile products and will not transport in a satisfactory manner if force is applied to them, particularly from above. For example the disclosed container 154 can transport a cake in the lower interior space 156 without damaging it, even if the shelf 207 above the lower interior space 156 is supporting the weight of a separate cake in the upper interior space 158. In another example, a cake can be loaded into the lower interior space 156 while items related to the service of a cake such as utensils, plates, and cutlery can be loaded into the upper interior space 158 without the shelf 207 deflecting into the lower interior space 156 to impact the cake.

[0030] The main blank 100 can be a first main blank, and the shelf blank 200 can be a first shelf blank, where a plurality of main blanks 100 like the first main blank 100 and a plurality of shelf blanks 200 like the first shelf blank 200 are palletized for shipping. The main blanks 100 can be palletized on one pallet, and the shelf blanks 200 can be palletized on a separate pallet. The main blanks 100 and shelf blanks 200 can be palletized on a single pallet together. The main blanks 100 and shelf blanks 200 can be palletized together as depicted in FIG. 5, where each shelf blank 200 is positioned on a respective main blank 100. Each shelf blank 200 can be adhered to a respective main blank 100 before the blanks are palletized.

[0031] With reference now to FIGS. 3 and 4, another embodiment of a blank system 20 is shown, similar to the blank system 10 with respect to FIGS. 1-2 and 5-13. The blank system 20 incorporates the features of the blank system 10 discussed above, and some distinguishing features are described below.

[0032] The blank system 20 includes a main blank 300 and a shelf blank 400. The main blank 300 has 7 panels 302, 304, 306, 308, 310, 312, 314 which fold across respective fold lines 350, 352, 354, 356, 358, 360, 362. Two end flaps 301, 315 fold across respective fold lines 348, 362, and join together or adhere together to enclose an interior space 365 of a container 367. The end flaps 301, 315 can also be referred to synonymously as panels in the present disclosure. The shelf blank 400 is similar to the shelf blank 200 of the blank system 100, except that it has a pair of opposed shelf end flaps 408, 410 in addition to the pair of opposed side shelf flaps 404, 406.

[0033] With reference now to FIGS. 14-18, the folding of the plurality of panels 302, 304, 306, 308, 301, 312, 314 across respective fold lines 350, 352, 354, 356, 358, 360, 362 and the folding of end flaps 301, 315 across fold lines 348, 362 is depicted. Visible in FIG. 17 are the flaps 324, 326, 328, 330 folded across fold lines 334, 338, 342, 346 to enclose the bottom 325 of the container 367. Visible in FIG. 18 is the partially erected container 367 around which the panels 302, 304, 306, 308, 310, 312, 314 and end flaps 301, 315 have partially enclosed an interior space 365. Also visible in FIG. 18 are portions 402, 404, 408, 410 of the shelf blank 400 connected to the main blank 300.

[0034] With reference now to FIGS. 19 and 20, the folding of one of the opposed side shelf flaps 404 is shown. The side shelf flap 404 folds to an acute angle with respect to the main shelf panel 402 across fold line 405 to provide clearance between the main shelf panel 402 and the main blank panel 314 when the main shelf panel 402 is folded across fold line 409 to form the shelf 411. The folding of the main shelf panel 402 occurs sequentially in FIG. 21, and the result of the folding of the main shelf panel 402 to form the shelf 411 is depicted in FIG. 24. Similar to the erecting of the container 154 of the blank system 10, the folding of the shelf blank 400 to form the shelf 411 creates a lower interior space 368 in the interior space 365 of the container 367.

[0035] With reference now to FIGS. 21-23, the top 327 of the container 367 is formed by the folding of flaps 316, 318, 320, 322 across respective fold lines 332, 336, 340, 344. The folding of flaps 316, 318, 320, 322 to create the top 327 of the container 367 also creates an upper interior space 370 within the interior space 365 of the container 367. FIG. 23 depicts the erected, closed container 367. The container 367, and the interior space 365 adopt an octagonal footprint in this embodiment.

[0036] FIG. 24 presents, as depicted in FIG. 13, a cross-sectional view of the partially erected container 367. The features of the shelf 207 of the blank system 10 are shared with the shelf 411 formed within the container 367 formed by the blank system 20. The shelf 411 has opposed shelf end flaps 408, 410 which are contoured to fit closely to the shape created by the panels 308, 310, 312. When the container 367 is not opened as in FIG. 13, the shelf end flaps 408, 410 also fit closely with the shape created by the panels 302, 304 and joined end flaps 301, 315.

[0037] The methods and systems of the present disclosure, as described above and shown in the drawings, provide for containers with an interior divider. While the apparatus and methods of the subject disclosure have been shown and described with reference to preferred embodiments, those skilled in the art will readily appreciate that changes and/or modifications may be made thereto without departing from the scope of the subject disclosure.
