For purposes of explanation and illustration, and not limitation, a partial view of an embodiment of a container in accordance with the disclosure is shown in FIG. 1 and is designated generally by reference character 100. Other embodiments of systems in accordance with the disclosure, or aspects thereof, are provided in FIGS. 2-16, as will be described. The systems and methods described herein can be used to form a structurally secure stackable corrugated paper container.

(20) As shown in FIGS. 1-4, a container 100 includes a first blank section 102 including a first side panel 104 with an opposed pair of corner panels 106, 108 extending form opposite ends of the first side panel 104 along fold lines 105, 107. The container 100 includes a second blank section 110 including a front panel 112 with an opposed pair of corner panels 114, 116 extending from opposite sides of the front panel along fold lines 115, 117. One of the corner panels 106, 108 of the first side panel 104 is adhered to one of the side panels 114, 116 of the front panel 110, forming a first double-thickness corner panel 118.

(21) The container 100 includes a third blank section 120 including a second side panel 122 opposite the first side panel 104 with an opposed pair of corner panels 124, 126 extending from opposite sides of the second side panel 122 along fold lines 125, 127. One of the corner panels 124, 126, of the second side panel 122 is adhered to one of the corner panels 114, 116 of the front panel 112, forming a second double-thickness corner panel 128.

(22) The container 100 comprises a fourth blank section 130 including a back panel 132 with an opposed pair of corner panels 134, 136 extending from opposite sides of the back panel 132 along fold lines 135, 137. One of the corner panels 134, 136 of the back panel 132 is adhered to one of the corner panels 124, 126 of the second side panel 122, forming a third double-thickness corner panel 138. One of the corner panels 134, 136 of the back panel 132 is adhered to one of the corner panels 106, 108 of the first side panel 104, forming a fourth double thickness corner panel 140. The first side panel 104, front panel 112, second side panel 122, and back panel 132 cooperate to surround an interior space 142 for containing product, e.g. product 144 as shown in FIG. 1. Each panel 104, 112, 122, 132, can include a plurality of aeration holes 290, however, corner panels 118, 128, 138, and 140 can be void of any such holes.

(23) Each of the first 102, second 110, third 120, and fourth 130 blank sections are of double-wall corrugated paper, so that the first 118, second 128, third 138, and fourth 140 double-thickness corner panels have a total two double-wall corrugated paper for a total of four plies thickness in each corner. For example, FIG. 5 shows a magnified cross-section of a portion of second blank 110, where the paper comprises two layers (A, A′) of corrugated paper. FIG. 6a shows a magnified cross-section of a portion of 138, where the overlap of corner panels 126 and 134 for example, form two layers of double wall (A, B) with an adhesive layer G in between, totaling 4 plies of corrugated paper (A, A′, B, B′). Each corner panel 114, 116, 134, 136 of the front and back panels 112, 132 can include a triangular bottom flap 146, 148, 150, 152 extending outward from the respective double-wall thickness corner panels 118, 138, 138, and 140 along fold lines 147, 149, 151, and 153 respectively (e.g. as best seen in FIG. 6). The first side panel 104, front panel 112, second side panel 122, and back panel 132 can be folded into a flat, palletizable form configured to be erected into the container 100 (e.g. as shown in FIG. 7).

(24) The container 100 further includes, a first bottom flap 154 extending from a bottom edge (corresponding to fold line 155) of the first side panel 104, a second bottom flap 156 extending from a bottom edge (corresponding to fold line 157) of the front panel 112, a third bottom flap 158 extending from a bottom edge (corresponding to fold line 159) of the second side panel 122, and a fourth bottom flap 160 extending from a bottom edge (corresponding to fold line 161) of the back panel 132. The first 154, second 156, third 158, and fourth 160 bottom flaps fold inward along their respective fold lines 155, 157, 159, and 161 to overlap and form a bottom panel 162, e.g. as shown in FIGS. 8-9.

(25) The top edges 164, 166, 168, 170 of the first side panel 104, front panel 112, second side panel 122, and back panel 132 form a top opening 172 into the interior space 142. The top edges 164, 166, 168, 170 can be free of panels extending therefrom.

(26) As shown in FIG. 10, a system 200 comprises, a container 100 including four of upright panels (corresponding to blanks 102, 110, 120, and 130) formed about an interior space 144, wherein the upright panels are connected by four corner panels (corresponding to corner panels 118, 128, 138, and 140), wherein the four upright panels and the four corner panels are of double wall corrugated paper and are configured to support a load of 1200 pounds (544 kg) bearing down on the four upright panels and the four corner panels.

(27) In the system 200, the container 100 is a first container 100a and further includes a pallet 250a on top of the first container 100a and a second container 100b on top of the pallet. The pallet 250a and second container 100b can weigh at least 1200 pounds (544 kg). In the system, the pallet 250a can be a first pallet and can further include a second pallet 250b on top of the second container 100b and a third container 100c on top of the second pallet 250b. The second pallet 250b and third container 100c can weigh at least 1200 pounds (544 kg). For example, the containers 100a-100c can be stacked atop one another in the direction of the upward pointing arrow shown in FIG. 10. The first container 100a can be free of triple wall corrugated material, however it is appreciated that any or all of containers 100a-100c can be free of triple wall corrugated material. It is contemplated that blanks 200 and 500 can form a container having a footprint sized to fit a standard full sized pallet, however, blanks 200 and 500 can also form a container having a footprint that is half of a standard pallet, or any other size desired.

(28) Referring back to FIGS. 2-4, a blank 300 as described above is folded into a container 100 by folding first side panel 104 inward along fold line 107, folding front panel 112 inward along fold lines 115 and 117, folding second side panel 122 inward along fold lines 125 and 127, folding back panel 132 inward along fold lines 135 and 137 to join corner panel 136 of the back panel 132 with corner panel 106 of first side panel around an interior space. Bottom flaps 154, 156, 158, and 160 can be folded inward along fold lines 155, 157, 159, and 161 to create a bottom panel. Bottom flaps 156 and 160 further include slots 180, 182, 184, and 186 configured to engage tabs 190, 192, 194, and 196 of bottom flaps 154 and 158 respectively.

(29) When folding bottom flaps 156 and 160 inwards, triangular bottom flaps 146, 148, 150, 152 are configured to detach from bottom flaps 156 and 160 along cut lines 247, 249, 251, and 253, and extend outward from the interior space 144 along fold lines 147, 149, 151, and 153. It is appreciated that cut lines 247, 249, 251, and 253 may be pre-cut, perforated, or any other suitable line of weakness easily breakable during folding.

(30) FIGS. 11-16 show another container 400 formed from a blank 500. Container 400 is substantially similar to that of container 100, and can be formed and folded in a substantially similar manner. Container 400 and blank 500 include, a first blank section 502 including a first side panel 504 with an opposed pair of corner panels 506, 508 extending form opposite ends of the first side panel 504 along fold lines 505, 507. The container 400 and blank 500 include a second blank section 510 including a front panel 512 with an opposed pair of corner panels 514, 516 extending from opposite sides of the front panel along fold lines 515, 517. One of the corner panels 506, 508 of the first side panel 504 is adhered to one of the side panels 514, 516 of the front panel 510, forming a first double-thickness corner panel 518.

(31) Panels 590, 600, 570, 580 can extend upwards from panels 504, 512, 522, 532 along fold lines 591, 601, 571, 581 respectively, and fold inward towards an interior of the container 400 (e.g. as shown in FIG. 14) so that all panels include two layers of double wall thickness corrugate. Print can appear on interior 172 (e.g. panels 590, 600, 570, 580) and exterior 174 (e.g. panels 504, 512, 522, 532) surfaces of the container 400. In this way, only one side of the first 502, second 510, third 520, and fourth 530 blank sections need be printed.

(32) In container 400, panels 504, 512, 522, and 532, and corners 518, 528, 538, and 540 all comprise two layers of double wall thickness corrugate. In addition to printing, having all panels include two layers of double wall thickness corrugate provides for added strength and stability of container 400 during stacking (e.g. stacking as shown in FIG. 10 with respect to container 100), storage, transport, or in use.

(33) The methods and systems of the present disclosure, as described above and shown in the drawings, provide for stronger stackable containers without the need for triple wall thickness corrugate. 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.
