BACKGROUND
1. Field
The field of the present disclosure relates generally to packaging containers and, more particularly, to a container formed from multiple blanks to provide a reinforced container with enhanced strength.
2. Description of Related Art
Corrugated fiberboard containers or boxes are known to come in a variety of shapes and constructions. At least some known containers that are used to transport and/or store products may be stacked on top of each other when the products are being transported or stored. The side walls of the containers on the lower layers of the stack are configured to support a weight of the containers on the upper layers of the stack. Products within the lower container may then be required to support the weight of the upper layers. Typical containers to achieve this support are generally three-piece “bliss” containers that include two side panels and a body panel, which can include the other two sides and top and bottom.
The conventional techniques have been considered satisfactory for their intended purpose. However, there is an ever present need for improved systems and methods for shipping, storing and displaying product. This disclosure provides a solution for this need.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
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 perspective view of an embodiment of a modular packaging system in accordance with the disclosure is shown in FIG. 1 and is designated generally by reference character 101. Other embodiments of systems in accordance with the disclosure, or aspects thereof, are provided in FIGS. 2-13, as will be described. The systems and methods described herein can be used to provide modular containers formed from corrugated fiberboard, e.g. cardboard blanks, that allow for a variety of different configurations that allow for use of different materials and/or thicknesses for a given portion of the container. Because of the variety of configurations, container 101 can be used in a variety of commercial areas, e.g. industrial, retail, and club store.
As shown in FIG. 1, packaging system includes a four piece container 101 having a bottom wall 102, a top wall 104 opposed to the bottom wall 102, a first end wall 106 connecting between the bottom wall 102 and the top wall 104, a second end wall 108 opposed to the first end wall 106 and connecting between the bottom wall 102 and the top wall 104. At least a portion of a first side wall 110 is connecting between the bottom wall 102 and the top wall 104. At least a portion of a second side wall 112 (shown in FIG. 4F) is opposed to the first end wall 106 and is connecting between the bottom wall 102 and top wall 104. The container 101 includes a plurality of corner walls 114. One of the corner walls 114 connects the first end wall 106 to the first side wall 110. A second of the corner walls 114 connects the second end wall 108 to the first side wall 110. A third of the corner walls 114 connects the first end wall 106 the second side wall 112. A fourth of the corner walls 114 connects the second end wall 108 to the second side wall 112.
With continued reference to FIG. 1, the top wall 104 and the bottom wall 102 are formed from identical top and bottom panels 116. The first and second end walls 106 and 108 are each formed from a combination of end flaps 132 and end panels 232. Each corner wall 114 is formed from a combination of corner flaps 134 and corner panel 234. Each side wall 110 is formed from a combination of side flaps, some of which extend downward or upward from respective top and bottom walls 104 and 102, others of which extend laterally from the corner walls 114. For example, each side wall 110 includes two side flaps 124 and two side flaps 224. Each side flap 224 includes an end edge 230. The end edges 230 of opposing side flaps 224 on a given side wall (e.g. side wall 110 or side wall 112) are spaced apart from one another. The top wall 104 and at least a portion of the first end wall 106 can be configured and adapted to be removed from the bottom wall 102 and at least a portion of the second end wall 108 to prepare the container for retail display, as described in more detail in FIGS. 4A-4F.
As shown in FIG. 2, a packaging blank system for forming container 101 includes a blank 100 having a top/bottom panel 116, with a plurality of side flaps 124 are foldably connected to the top/bottom panel about respective fold lines 125. A plurality of end flaps 132 are foldably connected to the top/bottom panel 116 about respective fold lines 131. Corner flaps 134 are foldably connected to each of the side flaps 124 about respective fold lines 127. The top/bottom 116 panel, end flaps 132, side flaps 124 and corner flaps 134 are configured to be formed into a tray 103, shown in FIGS. 4A-4D. End flaps 132 and side flaps 124 have the same height h. In order to form a container 101 (with both a top tray 103 and a bottom tray 103) two blanks 100 can be used to form two trays 103 (shown in FIG. 4E, described below).
With reference now to FIG. 3, the packaging blank system to form container 101 includes a blank 200 having an end panel 232, a pair of corner panels 234 each foldably connected to opposite sides of end panel 232 about respective fold lines 225, and a pair of side flaps 224. Each side flap 224 is foldably connected to a respective one of the corner panels 234 about a respective fold line 227. End panel 232, corner panels 234 and side flaps 224 are configured to form a container insert 205, shown in FIG. 4D.
As shown in FIGS. 4A-4F, an outer surface 220 of the second blank 200 is configured and adapted to be adhered to an inner surface 121 of first blank 100, then the panels of blank 100 and blank 200 are folded about their respective fold lines to form a half (e.g. half 101a or 101b) of a container 101. It is contemplated that the folding and assembly of blanks 100 and 200 into a given half (e.g. 101a or 101b) can be achieved using mandrel forming technology. Adhesive 122, shown in FIG. 2, is applied to the inner surface 121 of blank 100 during the container forming process in order to secure the blank 200 to blank 100. It is contemplated that product (not shown) can be loaded onto tray 103 prior to completion of container 101. For example, product can be loaded into tray 103 in the step shown in FIG. 4D for example. Container 101 is formed with a reduced body structure due to the shallow height h of trays 103, resulting in a reduction in material required as compared with traditional full-wrap containers, thereby reducing costs. During shipping, container 101 still maintains the desired strength due to container inserts 205 (e.g. “bliss” sides), which provide the desired structural support needed during stacking of multiple containers. Blank 200 that forms container inserts 205 can be formed from a thicker or stiffer material (e.g. a thicker or stiffer cardboard material) than that of blank 100. Once container 101 is ready for display, the top half 101a of the container can be removed, resulting in a retail-ready leave-behind portion 101b. Removal of the top half 101a can be made possible by choosing the proper strength for and type of adhesive 122. The leave-behind on shelf has a front shallow tray lip or the flap 132 lays down flat such that product is viewable.
As shown in FIG. 5, another embodiment of a blank 300, e.g. a first blank, is shown. Blank 300 is the same as blank 100, except that blank 300 includes support flaps 336, described below. Blank 300 includes a top/bottom panel 316, with a plurality of side flaps 324 and a plurality of end flaps 332 foldably connected to the top/bottom panel 316 about respective fold lines 325. Corner flaps 334 are foldably connected to each of the side flaps 324 about respective fold lines 327. Each corner flap 334 includes a respective support flap 336 foldably attached thereto about a respective fold line 351. The top/bottom 316 panel, end flaps 332, side flaps 324, corner flaps 334 and support flaps 336 are configured to be formed into a tray 303, shown in FIGS. 6A-6F. Support flaps 336 provide increased strength for the ends of tray 303. In order to form a container 301 (with both a top tray 303 and a bottom tray 303) two blanks 300 can be used to form two trays 303 (shown in FIG. 4E, described below).
As shown in FIGS. 6A-6F, the top/bottom 316 panel, end flaps 332, side flaps 324 and corner flaps 334 of blank 300 are configured to be folded about their respective fold lines to be formed into a tray 303. As shown in FIG. 6E, support flaps 336 can be folded inside of their respective end flaps 332 (bottom tray of FIG. 6E) or outside of their respective end flaps (top tray 303 of FIG. 6E). Container insert 205 is then used in conjunction with tray 303 and folded about its respective fold lines to form a container 301. Container 301 is the same as container 101 in that in includes the same number of sides, e.g a bottom wall 302, a top wall 304 opposed to the bottom wall 302, a first end wall 306 connecting between the bottom wall 302 and the top wall 304, a second end wall 308 opposed to the first end wall 306 and connecting between the bottom wall 302 and the top wall 304, a first side wall 310 and a second side wall 312, and corner walls 314, where each of the corner walls 314 connect between one of the end walls and one of the side panels. Similar to container 101, an outer surface 220 of the blank 200 is configured and adapted to be adhered to an inner surface 321 of the blank 300 to form a half (e.g. half 301a or 301b) of container 301. Folding and assembly can similarly be performed using mandrel technology and product can be loaded in a similar manner as described above with respect to container 101. Adhesive 322 (shown in FIG. 5) is applied to the inner surface 321 of blank 300 during the container forming process in order to secure the outer surface 220 of blank 200 to inner surface 321 of blank 300. As shown in FIG. 12, in some embodiments, instead of having two trays 303, only a bottom tray can be used to form an open top container. Additionally, as shown in FIG. 13, trays 303 formed from blanks 300 can be used with a container insert 505, which is the same as container insert 205 except instead of having a gap between edges 230 of two opposing inserts 205, edges of insert 505 abut those of an opposing insert 505 to form a fully enclosed container 501. Inserts 505 can similarly be used with tray 103 as well. Container 301 is similarly formed with a reduced body structure due to the shallow height h of trays 303, resulting in the same advantages as describe above. The shipping advantages described above and those associated with using inserts 205 are also present for container 301. Once container 301 is ready for display, the top half 301a of the container can be removed and the leave-behind can be used for display of product, in the same way as that described above relative to container 101.
As shown in FIG. 7, the packaging blank system includes a blank 400, e.g. a second blank, having end panels 432. Blank 400 can be used instead of two of blanks 200 in any of the trays described herein. Each end panel 432 has a pair of corner panels 434 each foldably connected to opposite sides of their respective end panel 432. Blank 400 includes tapered side flaps 424. Each tapered side flap 424 is foldably connected to a respective one of the corner panels 234. The end panel 232, the corner panels 234 and the side flaps 224 are configured to form a container insert 205. In the embodiment of FIG. 7, blank 400 includes a cut line 433 that separates two form container inserts 401a and 401b such that both inserts 405a and 405b that would, for example, be used in conjunction with a tray, e.g. tray 103 or tray 303, are formed in a single blank 400.
As shown in FIGS. 8A-8B, trays 303 formed from blanks 300 are used in conjunction with blank 400. Blank 400 is folded to form two container inserts 405a and 405b and nested within and adhered to trays 303 to form container 401. Container 401 is the same as container 101 in that in includes the same number of sides, e.g a bottom wall 402, a top wall 404 opposed to the bottom wall 402, a first end wall 406 connecting between the bottom wall 402 and the top wall 404, a second end wall 408 opposed to the first end wall 406 and connecting between the bottom wall 402 and the top wall 404, a first side wall 410 and a second side wall 412, and corner walls 414, where each of the corner walls 414 connect between one of the end walls and one of the side panels.
With continued reference to FIGS. 8A-8B, similar to container 301, an outer surface 420 of the blank 400 is configured and adapted to be adhered to an inner surface 321 of the blank 300 to form a half (e.g. half 401a or 401b) of a container 401. Adhesive 322 (shown in FIG. 5) is applied to the inner surface 321 of blank 300 during the container forming process in order to secure the outer surface 420 of blank 400 to inner surface 321 of blank 300. Because of the tapered side flaps 424, when blank 400 is formed into container inserts 405a and 405b, the sides 410 and 412 will form a ‘stadium style’ retail-ready container. To display product, the top half 401a can be removed from 401b in a similar manner to that described above for containers 101 and 301.
With reference now to FIG. 9, in accordance with another embodiment of the container insert, a blank 500 includes an end panel 532 of that includes four portions 532a-532d foldably connected to one another about fold lines 531a-531c. A first portion 532a and a second portion 532d are foldably connected to respective corner panels 534 about respective fold lines 525. Each corner panel 534 is foldably connected to a respective side flap 524 about a respective fold line 527. A third portion 532b and a fourth portion 532c of end panel 532 are foldably connected between the first and second portions 532a and 532d about respective fold line 531b. The third and fourth portions 532b and 532c are adjacent to one another and configured to be folded at oblique angles with respect to the first and second portions 532a and 532d to form a v-notched container insert 505. V-Notched multi angled end panel 532 can be utilized with trays 103 or 303 where additional stacking strength is required.
As shown in FIGS. 10A-10D, the top/bottom 316 panel, end flaps 332, side flaps 324 and corner flaps 334 are configured to be formed into a tray 303. Two container inserts 505 are then used in conjunction with two trays 303 to form container 501. Similar to container 101, an outer surface 520 of the blank 500 (specifically corner panels 534 and end portions 532a and 532) are configured and adapted to be adhered to an inner surface 321 of the blank 300 to form a half (e.g. half 501a or 501b) of a container 501. To form the other half, another insert blank 500 and another tray blank 300 are used. Adhesive 322 (shown in FIG. 5) is applied to the inner surface 321 of blank 300 during the container forming process in order to secure the outer surface 520 of blank 500 to inner surface 521 of blank 300. When combining halves 501a and 501b together to form container 501, an inner surface of tray 303 of half 501b may be adhered to an outer surface of insert 505 of half 501a or insert 505 of half 501a may simply be nested within tray 303 of half 501b. The same can be said for the connection between insert 505 of half 501b and the tray 303 of half 501a. Container 501 has the same advantages with respect to shipping and display as those described above with container 101, but also provides increased strength due to the v-notch 509.
The methods and systems of the present disclosure, as described above and shown in the drawings, provide for a modular packaging system that can be readily assembled to suit strength needs and retail-ready options. 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.
