BACKGROUND
[0001] The embodiments described in this document generally refer to a blank block to form a container and more particularly to a blank block to form a self-locking container having upper and lower stacking platforms.
[0002] At least some known containers that are used to transport and/or store products can be stacked on top of each other when the products are being transported or stored. The side walls of the containers in the lower layers of the stack are configured to support a weight of the containers in the upper layers of the stack. However, if the weight in a bottom container causes the side walls of the bottom container to protrude slightly, a bottom wall of a top container may rest in, or "nested" within, a cavity defined by the side walls of the lower container. Products within the lower container may then be needed to support the weight of the upper layers. As such, the products inside the containers can be damaged during transport and/or storage.
[0003] At least some such containers are at least partially formed with the use of a gluing and folding machine. More specifically, at least some of these containers are four-sided and are formed on a gluing and folding machine configured to form four-sided containers. BRIEF DESCRIPTION

[0020] The embodiments described in this document provide an eight-sided container that includes top and bottom stacking platforms. The upper stacking platform is defined by corner platform portions of a top wall, and the bottom stacking platform is defined by corner platform portions of a bottom wall, each of which extends beyond a boundary defined by the walls. sides. The container is constructed from a raw block of sheet material using a machine and/or by hand. The blank block includes a plurality of side panels coupled together in series by preformed generally parallel fold lines. For example, the raw block can be formed into a flat collapsed ("KDF") configuration using a gluing and folding machine configured to form four-sided containers in KDF configuration, and final container construction can be performed by hand and/or by another machine. In certain embodiments, at least one of the parallel fold lines is formed with increased stiffness compared to the others among the plurality of fold lines to facilitate forming the KDF container in a four-sided gluing and folding machine. The increased rigidity inhibits involuntary rotation of the blank block around the at least one bend line as the blank moves through the four-sided bending and gluing machine.
[0021] In certain embodiments, the container includes an insert configured to reinforce at least one sidewall. The insert can either be secured to at least one side wall, such as by stapling or gluing, or simply positioned against the at least one side wall. The at least one sidewall reinforced with the insert enables the containers described herein to be stronger than similar containers without reinforced sidewalls, especially when subjected to vertical compression. For example, inserts can be inserted in the field as containers are positioned at the lower levels of a stack of containers, enhancing the ability of the lower layer containers to support the upper layers of the stack.
[0022] In one embodiment, the container is manufactured from a cardboard material. The container, however, can be manufactured using any suitable material, and therefore is not limited to a specific type of material.

[0046] To form the collapsed flat container 300 in the exemplary mode, the raw block 100 is rotated around the fold line 132 so that the inner surface 12 of the glue panel 142, the second end panel 138 and the fourth corner panel 134 are in substantially face-to-face contact with the inner surface 12 of the second side panel 130. The blank 100 is also rotated about the fold line 116 so that the inner surface 12 of the first side panel 114 is at substantially face-to-face contact with the inner surface 12 of the second corner panel 118, the first end panel 122, the third corner panel 126 and the second side panel 130, and the inner surface 12 of the first corner panel 110 is at substantially face-to-face contact with the outer surface 14 of the glue panel 142. An adhesive disposed on at least one of the inner surface 12 of the first corner panel 110 and the outer surface 14 of the foot. glue ring 142 is used to couple first corner panel 110 and glue panel 142 together to form fabrication joint 302.
[0047] The formation of the disassembled flat container 300 also rotates the inner surface 12 of the first lower side panel 180 into substantially face-to-face contact with the inner surface 12 of the first lower end panel 184, and rotates the inner surface 12 of the second panel of lower end 192 in substantially face-to-face contact with the inner surface 12 of the second lower side panel 188. Similarly, the formation of the flat collapsed container 300 also rotates the inner surface 12 of the first upper side panel 150 into substantially face-to-face contact with inner surface 12 of first top end panel 154, and pivot inner surface 12 of second top end panel 162 into substantially face-to-face contact with inner surface 12 of second top side panel 158.
[0048] In certain embodiments, at least one of the fold lines 112, 116, 120, 124, 128, 132, 136 and 140 is formed with increased stiffness compared to the other fold lines 112, 116, 120, 124, 128, 132, 136 and 140. The increased stiffness inhibits involuntary rotation of the blank block around at least one of the fold lines 112, 116, 120, 124, 128, 132, 136 and 140, as with the blank block. it moves through a gluing and folding machine, such as a gluing and folding machine designed to form four-sided containers. For example, the at least one of the fold lines 112, 116, 120, 124, 128, 132, 136 and 140 which has increased stiffness is different from the two of the fold lines 112, 116, 120, 124, 128, 132, 136 and 140 around which the blank 100 is rotated to form a collapsed flat container 300.
[0049] For example, Figure 2 illustrates a rough block 100 moving through a gluing and folding machine 10. The gluing and folding machine 10 is any gluing and folding machine that is suitable for forming flat disassembled configurations of four containers sides from raw blocks of sheet material. Folder gluing machine 10 includes a suitable transport system 12 for moving raw block 100 through folder gluing machine 10 in a machine travel direction 14 and a plurality of folding arms 16. The plurality of folding arms 16 is configured to rotating the blank 100 shown in Figure 1 in the collapsed flat container 300 shown in Figure 3 as the blank 100 is moved through the gluing and bending machine 10. In certain embodiments, the gluing and bending machine 10 also includes an adhesive station (does not shown) configured to apply adhesive to at least one of inner surface 12 of first corner panel 110 and outer surface 14 of glue panel 142 to facilitate formation of fabrication joint 302.
[0050] In some embodiments, at least one of the plurality of bending arms 16 is a stationary contoured rail passively urging at least one of the plurality of rough block side panels 100, such as the first side panel 114 and/or the second end panel 138, for rotation toward one another among the plurality of side panels, such as first end panel 122 and/or second side panel 130, as the raw block 100 is driven through the gluing and folding machine 10 Additionally or alternatively, at least one of the plurality of bending arms 16 is a movable arm that actively urges one of the plurality of rough block side panels 100 for rotation toward the other of the plurality of side panels. Although only two bending arms 16 are shown in Figure 2, it is to be understood that the gluing and bending machine 10 may include any suitable number of bending arms or rails 16 and/or other components that enable the collapsed flat container 300 to be formed to from the raw block 100 as described in this document.
[0051] In the example mode, the gluing and folding machine 10 is configured to rotate the stock block 100 around fold lines 132 and 116 to the flat disassembled configuration shown in Figure 3. As the folding arms 16 rotate the stock block 100 around fold lines 132 and 116 for the disassembled flat configuration shown in Figure 3, fold line 136 supports at least a portion of a weight of second end panel 138, second top end panel 162, and second. lower end panel 192. Additionally, at least one bending arm 16 transfers force to second end panel 138. Weight and/or force may cause second end panel 138 to rotate about fold line 136, instead of just around fold line 132 as intended. Such involuntary rotation about the fold line 136 potentially misaligns the rough block portions 100 and/or interrupts the operation of the gluing and folding machine 10 during the formation of collapsed flat container 300. In the exemplary embodiment, the fold line 136 is formed with increased stiffness compared to bend lines 112, 116, 120, 124, 128, 132 and 140 to inhibit involuntary rotation of blank block 100 around bend line 136. Thus, blank block 100 facilitates a formation of an eight-sided container in a flat configuration disassembled using a gluing and folding machine configured for four-sided containers. In certain embodiments, the increased rigidity of fold line 136 is not so rigid as to prevent a subsequent voluntary rotation around fold line 136, for example, when a user or other machine applies a force to lift container 400 to from the disassembled flat container 300.
[0052] In certain embodiments, the increased stiffness of at least one of the fold lines 112, 116, 120, 124, 128, 132, 136 and 140 is imparted by a method for preforming at least one of the fold lines 112, 116, 120, 124, 128, 132, 136 and 140. For example, the increased stiffness of at least one of the fold lines 112, 116, 120, 124, 128, 132, 136 and 140 is imparted during a cut. per blank block matrix 100. In some embodiments, the at least one of the fold lines 112, 116, 120, 124, 128, 132, 136 and 140 which has increased stiffness is formed as a perforation line and each of the another of the fold lines 112, 116, 120, 124, 128, 132, 136 and 140 is formed by a fold groove.
[0053] More specifically, in the exemplary embodiment, each of the fold lines 112, 116, 120, 124, 128, 132 and 140 is preformed using an 8-point 2.24 centimeter (0.883) folding groove inch), while bend line 136 is preformed with relatively increased rigidity during die cutting of blank block 100 as a perforation line using a 0.63 centimeter (0.25 inch) knife with 0 spacing .95 centimeter (0.375 inch). In alternative embodiments, at least one of the fold lines 112, 116, 120, 124, 128, 132 and 140 is preformed using another groove suitable for a fold line, such as, but not limited to, a between a 2.18 centimeter (0.860 inch) 4-point groove and a 2.21 centimeter (0.870 inch) four-point groove. Furthermore, in alternative embodiments, fold line 136 is preformed by a perforation of any other suitable knife size and/or spacing or any other suitable method that provides increased rigidity relative to fold lines 112, 116 , 120, 124, 128, 132 and 140. In still other alternative embodiments, the increased stiffness of at least one of the fold lines 112, 116, 120, 124, 128, 132, 136 and 140 is imparted by a method for pre - forming at least one of the fold lines 112, 116, 120, 124, 128, 132, 136 and 140 in another suitable way.
[0054] Referring to Figures 1 and 3 to 5, to construct the container 400 from a disassembled flat container 300, the first side panel 114 is moved out of communication with the first end panel 122, and the second panel 138 is moved out of communication with the second side panel 130. For example, a user grasps at least one of the vent holes 144 of the first side panel 114 and the vent holes 146 and 148 of the second end panel 138, and pulls upward so that the first side panel 114 moves in the opposite direction to the first end panel 122 and the second end panel 138 moves in the opposite direction to the second side panel 130. As another example, a user pushes the line fold 116 and fold line 132 together, forcing first side panel 114 away from first end panel 122 and second end panel 138 away from second side panel 130. in the other example, a machine (not shown) applies a vacuum suction device to at least one of the first side panel 114 and the second end panel 138 so that the first side panel 114 moves in the opposite direction to the first panel. 122 and second end panel 138 moves in the opposite direction to second side panel 130. In alternative embodiments, first side panel 114 is moved away from first end panel 122 and second end panel 138 is moved. in the opposite direction to the second side panel 130 in any suitable way.
[0055] Moving the first side panel 114 out of communication with the first end panel 122, and the second end panel 138 out of communication with the second side panel 130 also moves the first lower side panel 180 out of communicating with first lower end panel 184 and moving second lower end panel 192 out of communication with second lower side panel 188. Similarly, moving first side panel 114 out of communication with first end panel 122, and second end panel 138 out of communication with second side panel 130, also moves first top side panel 150 out of communication with first top end panel 154 and moves second top end panel 162 out of communication with the second upper side panel 158.
[0056] To continue construction of container 400 in exemplary mode, first lower side panel 180 is rotated around fold line 182 toward inner surface 102 of first side panel 114, and second lower side panel 188 is rotated about fold line 190 toward inner surface 102 of second side panel 130 so that first lower side panel 180 is substantially perpendicular to first side panel 114 and second lower side 188 is substantially perpendicular to second side panel 130. The first lower end panel 184 is rotated about the fold line 186 toward the inner surface 102 of the first end panel 122. The second portion 242 of the first lower end panel 184 is rotated slightly around the score line 238 toward the inner surface 102 of the first portion 240. In the exemplary embodiment, the first lower end panel 184 is not bent sufficiently to crease score line 238 when second portion 242 is rotated toward first portion 240. Instead, slight rotation of second 242 facilitates insertion of first locking tab 220 into second slot. locking 212 and inserting the second locking tab 222 into the third locking groove 214.
[0057] Similarly, the second lower end panel 192 is rotated about the fold line 194 towards the inner surface 102 of the second end panel 138. The second portion 272 of the second lower end panel 192 is rotated slightly around. of the score line 268 toward the inner surface 102 of the first portion 270. In the exemplary embodiment, the second lower end panel 192 is not bent sufficiently to crease the score line 268 when the second portion 272 is rotated toward the first. portion 270. Instead, the slight rotation of second 272 facilitates insertion of third locking tab 250 into fourth locking groove 216 and insertion of fourth locking tab 252 into first locking groove 210.
[0058] The first locking tab 220 and the second locking tab 222 are inserted into the second locking slot 212 and the third locking slot 214, respectively, so that the first slot 228 cooperates with the second locking slot 212 and second slot 232 cooperates with third locking groove 214 to couple first lower end panel 184 to each of first lower side panel 180 and second lower side panel 188. Similarly, third locking tab 250 and fourth locking tab 252 are inserted into fourth locking slot 216 and first locking slot 210, respectively, so that first slot 258 cooperates with second locking slot 216 and fourth slot 262 cooperates with first locking slot 210 to couple second lower end panel 192 to each of first lower side panel 180 and second lower side panel 188.
[0059] In addition, the elements of the lower locking mechanism 280 are configured so that each of the lower panels 180, 184, 188 and 192 is substantially perpendicular to each of the side panels 110, 114, 118, 122, 126, 130, 134 and 138 when bottom panels 180, 184, 188 and 192 are coupled together. More specifically, in the exemplary mode, when each of the locking tabs 220, 222, 250 and 252 is inserted into the respective slot among the locking slots 212, 214, 216 and 210 so that the lower panels 180, 184, 188 and 192 are coupled together, each of the lower panels 180, 184, 188 and 192 is forced into a substantially perpendicular relationship to each of the side panels 110, 114, 118, 122, 126, 130, 134 and 138. bottoms 180, 184, 188 and 192 form a bottom wall 442 of container 400.

In certain embodiments, at least two of the first top side panel 150, second top side panel 158, first top end panel 154, and second top end panel 162 are coupled together to secure top wall 446, for example, during shipping and storage of container 400. For example, first top side panel 150 and second top side panel 158 are coupled together using tape. For another example, an adhesive is used to couple the inner surface 102 of each first top side panel 150 and second top side panel 158 to the outer surface 104 of each of the first top end panel 154 and the second top end panel 162 In alternative embodiments, at least two of the first top side panel 150, the second top side panel 158, the first top end panel 154, and the second top end panel 162 are coupled together in any suitable way that enables the container 400 works as described in this document. In still other alternative embodiments, none of the first top side panel 150, the second top side panel 158, the first top end panel 154, and the second top end panel 162 are coupled together.

Top wall 446, including at least one top corner platform portion 460, defines top stacking platform 462 of container 400.
[0067] In the exemplary embodiment, the top wall 446 includes four top corner platform portions 460, each proximate to an upper edge of a respective wall among corner walls 410, 418, 426, and 434. of upper and lower corner platform 460 is shaped so that the upper stacking platform 462 is generally rectangular in shape, with the corners of the rectangular shape extending outside the boundary 450.
[0068] Figures 6 and 7 illustrate a second embodiment of a raw block used to form a second embodiment of a container. Specifically, Figure 6 is a top plan view of an exemplary embodiment of a raw block 600 of sheet material. Figure 7 is a top perspective view of a container 800 formed from blank block 600.
[0069] The 600 blank block is similar in many respects to the 100 blank block, but the 600 blank block has a different arrangement of top panels as will be described in this document. Like the rough block 100, the rough block 600 has the first surface or inner surface 102 and the second opposite surface or outer surface 104 and defines the first edge 106 and the second opposite edge 108. In exemplary mode, similarly to the rough block 100 , the blank block 600 includes, from the first edge 106 to the second edge 108, a plurality of side panels 610, 614, 618, 622, 626, 630, 634 and 638 coupled together in series along a plurality of rows of preformed generally parallel folds 612, 616, 620, 624, 628, 632, 636 and 640. In the exemplary embodiment, the plurality of side panels include, from the first edge 106 to the second edge 108, a first corner panel 610 , a first side panel 614, a second corner panel 618, a first end panel 622, a third corner panel 626, a second side panel 630, a fourth corner panel 634, a second end panel 638, and a panel of glue 642. Also like block b 100, blank block 600 also includes elongate vent holes 644, circular vent holes 646, and semi-circular vent holes 648. It should be understood that, in alternative embodiments, any panel and/or portion of blank block 600 may include attire. minus one of the vent holes 644, 646 and 648, each of which has any suitable shape and/or configuration. In a particular embodiment, blank block 600 does not include any one of vent holes 644, 646 and 648.
[0070] Furthermore, like the raw shoot 100, in certain embodiments, at least one of the fold lines 612, 616, 620, 624, 628, 632, 636 and 640 is preformed to have a stiffness greater than a stiffness of the other fold lines 612, 616, 620, 624, 628, 632, 636 and 640. For example, the rough block 600 can be rotated around two others among the fold lines 612, 616, 620, 624, 628 , 632, 636 and 640 to form a collapsed flat container (not shown) of similar shapes as for the collapsed flat container 300 and, as described above for the blank 100, the increased rigidity of one of the fold lines 612, 616 , 620, 624, 628, 632, 636 and 640 inhibits involuntary rotation of the blank block around the at least one bend line, such as while blank block 600 moves through a gluing and bending machine. The at least one fold line may be formed in any suitable way as described above. In the exemplary embodiment, fold line 636 is preformed to have a stiffness greater than a stiffness of fold lines 612, 616, 620, 624, 628, 632, and 640.
[0071] Furthermore, like the blank block 100, the blank block 600 includes a plurality of lower panels 680, 684, 688 and 692 that include a lower locking mechanism 780, which functions in a similar manner as the lower locking mechanism 280 described above. In the exemplary embodiment, the lower locking mechanism 780 includes generally L-shaped mirror image locking grooves 710 and 712 in the first lower side panel 680, generally mirror image locking grooves, with L-shaped 714 and 716 on the second lower side panel 688, locking tabs 720 and 722 on the first lower end panel 684, and locking tabs 750 and 752 on the second lower end panel 692. Additionally, the lower end panels 684 and 692 include the dotted lines 738 and 768, respectively.
[0072] In certain embodiments, at least one of the plurality of lower panels 680, 684, 688 and 692 includes at least a lower corner portion 700 that extends adjacent to a free lower edge 702 of a respective panel among the panels. corner 610, 618, 626 and 634 and a glue panel 642. When container 800 is formed from blank block 600, each lower corner portion 700 is configured to extend beyond a boundary 850 defined by the plurality of walls container sides 800 to at least partially form a lower stacking platform 882. In the exemplary embodiment, first lower side panel 680 includes a first lower corner portion 700 adjacent to free lower edge 702 of first corner panel 610. lower end panel 684 includes a first lower corner portion 700 adjacent to the free lower edge 702 of second corner panel 618 and a second lower corner portion 700 adjacent to free lower edge 702 of third corner panel 626. Second lower side panel 688 includes a first lower corner portion 700 adjacent to free lower edge 702 of third corner panel 126. Second lower end panel 692 includes a first lower corner portion 700 adjacent to free lower edge 702 of fourth corner panel 634 and a second lower corner portion 700 adjacent to free lower edge 702 of glue panel 642.
[0073] The gross block 600 also includes a plurality of top panels 650, 654, 658 and 662. In the exemplary embodiment, the plurality of top panels includes a first top side panel 650, a first top end panel 654, a second top side panel 658 and a second top end panel 662. More specifically, the first top side panel 650 extends from an upper edge of the first side panel 614 defined by a fold line 652, the first top end panel 654 extends from a top edge of first end panel 622 defined by a fold line 656, second top side panel 658 extends from a top edge of second side panel 630 defined by a fold line 660, and second top end panel 662 extends from a top edge of second end panel 638 defined by a fold line 664. fold lines 652, 656, 660 and 664 is generally perpendicular to fold lines 612, 616, 620, 624, 628, 632, 636 and 640.

Each stabilizing slot 1314 and 1316 is generally semi-ovoid in shape, and the second stabilizing slot 1316 is a mirror image of the first stabilizing slot 1314.
[00107] Furthermore, in the exemplary mode, the first upper side panel 1350 includes a free edge 1318 that defines a first stabilizing tab 1320 and a second stabilizing tab 1322. Stabilizing tabs 1320 and 1322 form a portion of the stabilizing mechanism. upper locking 1380. More specifically, stabilizing tab 1320 is configured to be received by stabilizing groove 1316 and stabilizing tab 1322 is configured to be received by stabilizing slot 1314 when the container (not shown) is erect. Free edge 1318 includes a first vertical portion 1323, a first angled portion 1324, a first horizontal portion 1326, a first slit 1328, a middle horizontal portion 1330, a second slit 1332, a second horizontal portion 1334, a second angled portion 1336 and a second vertical portion 1337. First stabilizing tab 1320 is defined by first vertical portion 1323, first angled portion 1324, first horizontal portion 1326 and first slot 1328, and second stabilizing tab 1322 is defined by second slot 1332 , second horizontal portion 1334, second angled portion 1336 and second vertical portion 1337. Alternatively, stabilizing tabs 1320 and/or 1322 and/or free cap 1318 have any suitable configuration that enables blank block 1300 to function as required. described in this document. Furthermore, in an alternative embodiment, the middle horizontal portion 1330 includes a middle notch (not shown). In alternative embodiments, first upper side panel 1350 further includes a score line (not shown) similar to score line 1388.
[00108] Thus, in the example embodiment of Figure 13, the upper locking mechanism 1380 includes locking grooves 1310 and 1312 and locking tabs 1370 and 1372, as well as stabilization grooves 1314 and 1316 and stabilization tabs 1320 and 1322. Furthermore, similarly to the blank block 100, at least one of the plurality of top panels 1350, 1354, 1358 and 1362 includes at least an upper corner portion 1396 that extends adjacent a free top edge 1398 of a respective corner panel. and/or glue panel, and each upper corner portion 1396 is configured to at least partially form an upper stacking platform of the container. A container (not shown) may be formed from blank block 1300 in the same way that container 400 is formed from blank block 100, but including a top wall with locking mechanism 1380 formed in a similar fashion to the bottom wall. 442 of container 400.
[00109] It should be understood that, in alternative embodiments, any raw block contemplated herein includes any components and/or suitable configuration of a locking mechanism, such as any of the upper locking mechanisms 1180, 1280, and 1380 , which enables a container as contemplated herein to be properly formed. It should also be understood that, in alternative embodiments, any raw block contemplated herein includes any suitable components and/or configuration of a locking mechanism, such as any of the upper locking mechanisms 1180, 1280, and 1380, which enables a container as contemplated herein to be properly formed.
[00110] The modalities described above provide containers with top and bottom stacking platforms for shipping and/or storing products in a stacked configuration. Due to the fact that containers include top and bottom stacking platforms, a tendency for a bottom wall of an top container to sit in, or "nested" within, a cavity defined by the side walls of the bottom container is reduced or eliminated. The embodiments described above also provide eight-sided containers constructed from blank blocks that include a plurality of side panels coupled together in series by preformed generally parallel fold lines. Due to the fact that at least one of the parallel fold lines is formed with increased stiffness compared to the others of the plurality of fold lines, a tendency for involuntary rotation of the blank around the at least one fold line is reduced or deleted. Thus, the blank blocks facilitate formation of an eight-sided container in a flat disassembled configuration using a gluing and folding machine configured for four-sided containers, reducing or eliminating a need to modify or reconfigure the machine. In addition, the embodiments described above provide an optional insert for a reinforcing structure that increases a stacking strength of some such containers.
[00111] Exemplary modalities of blank blocks and methods for forming containers are described in detail above. Apparatus and methods are not limited to the specific embodiments described herein, but rather apparatus components and/or method steps may be used independently and separately from other components and/or steps described herein. For example, the methods can also be used in combination with other containers and methods and are not limited to practice only with the containers and methods described herein. Instead, the example embodiments can be deployed and used in conjunction with many other container applications.
[00112] Although specific features of various embodiments of the invention may be shown in some drawings and not others, this is only for convenience. In accordance with the principles of the invention, any feature of one design may be named and/or claimed in combination with other features in any other design.
