FIG. 8 shows a front view of an assembled back panel 700 for use in the assembled shipping crate. FIG. 9 shows a back view of the assembled back panel 700 of FIG. 8. FIG. 10 shows the four walls 300a-d of FIG. 4 assembled with the back panel 700 of FIG. 8.

[0068] As shown, the shipping crate 100 has a plurality of walls 300a-d, typically four walls, as shown. Each wall 300a-d comprises at least two distinct layers 310, 320 of rigid material. The rigid material is a non-corrugated material, such as a solid board. The individual boards may comprise multiple plies of paperboard, and may be referred to as ply board.

[0069] Generally, the crate 100 described herein may be assembled from 100% recyclable materials. Accordingly, the boards used are typically paper boards or other solid ply board, while tapes and glues are biodegradable or recyclable. In some embodiments, the sealing tape may be reinforced with fiberglass thread, which is screened out as part of the paper repulping process. In such embodiments, the fiberglass thread may be the only component that is not biodegradable. In some embodiments, certain components, such as handles and skids discussed in more detail below, may be fixed to the crate 100 using non-biodegradable materials. Such materials may be, for example, staples, which may be used minimally and may be removed prior to recycling the crate 100.

[0070] The two distinct layers 310, 320 forming each wall are sized such that a first wall layer 310 of the at least two layers of each wall has sides 330 and a first thickness 340, and a second wall layer 320 has sides 350 extending past each of the sides 330 of the corresponding first wall by the first thickness. In this way, when viewed with the first layer 310 on top, the second layer 320 extends on each side 330 of the first layer by a width corresponding to the thickness 340 of the first layer. The second layer 320 thereby provides a lip extending past the first layer 310.

[0071] As shown in FIG. 6, the two layers 310, 320 may be initially bonded together prior to assembling the plurality of walls 300a-d into a partial assembly. In some embodiments, this may be by applying an adhesive between the layers and taping the layers together, as shown. In some embodiments, the adhesive is applied and the layers 310, 320 are then fixed together in other ways, such as by stapling the wall layers. Such stapling serves to clamp the layers 310, 320 together as the adhesive dries, resulting in a strong bond between layers.

[0072] In the embodiment shown, all boards have layers with thicknesses that are substantially the same as the first thickness 340. Some components are formed from multiple layers, while others are formed from single layers. The boards having the same thicknesses 340 generally allows panels to interlock such that the unique geometry described herein is possible and reinforces the stability of the shipping crate 100 as a whole.

[0073] The shipping crate 100 further comprises a back panel 700 with a first back panel layer 710 formed from the rigid material and at least a partial second back panel layer 720a-d. As shown, the second back panel layer may itself comprise distinct components 720a-d. However, in other embodiments, the second back panel may be a complete back panel.

[0074] The first back panel layer 710 has sides 730 and a thickness corresponding to the first thickness 740, and as discussed above, the thickness of the first back panel layer is typically identical, or substantially similar to, the first thickness 340. Similarly, the second back panel layer 720a-d, whether it is a single complete panel layer or whether it is formed form discrete components, typically also has a thickness corresponding to the first thickness 340. When assembled, the second back panel layer 720a-d extends past each of the sides 730 of the first back panel layer 710 by the first thickness 340. As such, when viewed with the first back panel layer 710 on top, as shown in FIG. 9, the second back panel layer 720a-d extends on each side 730 of the first back panel layer by a width corresponding to the thickness 340 of the first layer.

[0075] When the walls 300a-d and the back panel 700 are assembled, the first wall layers 310 of each of the plurality of walls 300a-d combine to form a first post P and lintel L assembly and the second wall layers 320 of each of the plurality of walls 300a-d combine to form a second post P and lintel L assembly. The second post and lintel assembly is distinct from the first such assembly, and the two assemblies are nested together. This arrangement is most clearly seen in FIG. 5, but appears throughout the figures. It is noted that the post and lintel assembly described here will repeat throughout the shipping crate 100 shown, and for each such assembly, the post will be labeled P and the lintel will be labeled L for clarity.

[0076] The first 310 and second 320 layers are bonded, or otherwise laminated together such that they are fixed in the positions described. Accordingly, because the second layer 320 of each wall 300a-d extends past the sides 330 of the first layer 310 of the corresponding wall, the two distinct post P and lintel L arrangements are nested, and tend to reinforce each other. As such, for any given wall 300a-d, both the first and second layer 310, 320 will form either a post P or a lintel L.

[0077] As noted above, the back panel 700 comprises a first back panel layer 710 and a second back panel layer 720a-d. The second back panel layer 720a-d typically comprises a set of four battens which define a border of the first back panel layer 710, when viewed from the back, as shown in FIG. 8. When viewed from the front, as shown in FIG. 9, each batten extends past the corresponding side 730 of the first back panel layer 710 by the first thickness 340, as discussed above.

[0078] The four battens 720a-d comprising the second back panel layer form a third post P and lintel L assembly, and when assembled with the walls 300a-d, the two battens 720b, d forming posts P of the third post and lintel assembly align with the walls 300b, d containing posts of the first and second post and lintel assemblies. Similarly, the two battens 720a, c forming lintels L of the third post and lintel assembly align with the walls 300a, c containing lintels of the first and second post and lintel assemblies.

[0079] When assembled, the first back panel layer 710 rests against and abuts the sides 330 of the first wall layer 310 of each of the corresponding plurality of walls 300a-d. The first back panel layer 710 is then enclosed on all sides 730 by the second wall layers 320 of the plurality of walls 300a-d. In this way, the first back panel layer 710, taken as a whole, functions as a post while the second wall layer 320 forms a lintel for yet another post and lintel assembly. The battens forming the second back panel layer 720a-d rest on and abut the sides of the second wall layer 320 of each of the plurality of walls 300a-d.

[0080] In this way, the sides 730 of the first back panel layer 710 abut the lip of the second wall layer 320 of each of the four walls 300a-d, while the second back panel layer rests outside of a width of the walls and abuts a side of the second wall layer 320 of each of the walls. Accordingly, when assembled sides of the second back panel layers 720a-d are flush with an outer surface of the second wall layers 320 of each of the walls 300a-d.

[0081] In some alternative embodiments, when assembled, the second back panel layer 720a-d rests against the sides 330 of the first wall layer 310 of each of the corresponding plurality of walls 300a-d. The first back panel layer 710 is then fully enclosed by the first wall layers 310.

[0082] It is noted that in many embodiments, two of the plurality of walls 300b, d may be defined as side walls, one wall 300a may be defined as a top wall, and one wall 300c may be defined as a bottom wall. Accordingly, as noted above, the two first wall layers 310 and the two second wall layers 320 of the side walls 300b, d are the posts P of the first and second post and lintel assemblies respectively. Similarly, the first and second wall layers 310, 320 of each of the top wall 300a and the bottom wall 300c are lintels L for the corresponding assemblies.

[0083] The second back panel layer 720a-d may then comprise a plurality of battens arranged in a third post and lintel assembly defining a border of the first back panel layer 710, and when assembled, the battens 720b, d adjacent the side walls 300b, d are the posts P of the third post and lintel assembly, and the battens 720a, c adjacent the top and bottom walls 300a, c are the lintels L for the corresponding assemblies. As discussed below with respect to FIG. 13, the same pattern is repeated with respect to the frame battens 1300a-d.

[0084] It will be understood that the crates 100 described herein can be assembled in a wide variety of dimensions, so long as the various post and lintel configurations are repeated. Accordingly, the walls 300a-d may be provided with different widths in order to correspond to a desired interior space and shape. As such, while the crate 100 illustrated herein is generally flat, with a back panel 700 larger than the side walls 300a-d, this configuration is provided as an example, and other configurations are contemplated.

[0085] FIG. 11 shows a cleat 1100 positioned relative to the partially assembled shipping crate 100 of FIG. 10. FIG. 12 shows the partially assembled shipping crate 100 with cleats 1100 applied to each corner.

[0086] As shown, the shipping crate 100 is provided with corner cleats 1100. Each cleat comprises two panels 1110, 1120 of rigid material butted together at a joint 1130. When assembled, each joint of two walls 300a-d of the crate 100 is overlayed with a corresponding cleat 1100.

[0087] Generally, each of the plurality of walls 300a-d has a substantially similar second wall layer width 360, as shown in FIG. 2. As such, when the four walls 300a-d are assembled, a front and back of that assembly are flush. This is seen, for example, in FIGS. 3 and 4, where the walls are assembled alone. Each of the two panels 1110, 1120 forming the cleats 1100 are then provided with a length 1140 larger than the second wall layer width 360, and are butted together at the joint 1130 along their lengths.

[0088] Typically, the panels 1110, 1120 of the cleats 1100 are longer than the second wall layer width 360 by the first thickness 340 or twice the first thickness 340. Accordingly, when fixed to the walls 300a-d, a second end 1150 of each cleat 1100 extends past a front edge of each of the walls by the first thickness 340. As noted above, in some embodiments, at least part of the back panel 700, such as the battens 720a-d, rests outside of the walls 300a-d and abuts the sides of the second wall panels 320. In such embodiments, the cleats 1100 each have a length 1130 longer than the second wall layer width 360 by twice the first thickness 340.

[0089] When assembled, as shown in FIG. 12, the two panels 1110, 1120 of each cleat 1100 are butted together in a configuration matching the corresponding joint of the corresponding two walls 300a, d. Accordingly, as is most clearly shown in FIG. 11, where a side wall 300d of the crate forms a post P and a top wall 300a forms a lintel L for a post and lintel assembly, the cleat 1100 overlaying that will be arranged such that a panel 1120 of the cleat overlaying the side wall 300d abuts a side of the panel 1110 overlaying the top wall 300a. Accordingly, each panel 1110, 1120 extends past the underlying second wall layer 320 by the first thickness 340 at the joint 1130.

[0090] FIG. 13 shows the partially assembled shipping crate 100 with frame battens 1300a-d applied at a front of the crate. FIG. 14 shows the partially assembled shipping crate 100 of FIG. 13 with the battens 1300a-d in an open position.

[0091] As shown, the frame battens 1300a-d are rotatably fixed to the second wall layer 320 of each wall 300a-d opposite the back panel 700. When in a closed configuration, as shown in FIG. 13, a first face 1310 of each of the frame battens 1300a-d rests on the sides of the second wall layer 320 of each of the corresponding plurality of walls 300a-d. A second face 1320 of each of the frame battens 1300a-d opposite the first face 1310 is flush with the second ends 1150 of each of the cleat panels 1110, 1120. As shown, when in the closed configuration, the frame battens 1300a-d form a fourth post P and lintel L assembly. This arrangement may be symmetric in the back, such that each panel 1110, 1120 of the cleat 1100 extends past the back of the underlying wall 300a-d by the first thickness 340, such that they then enclose the second back panel layer 720. The second end of each cleat panel is then flush with an outer surface of the second back panel layer 720.

[0092] As shown, in some embodiments, the battens 1300a-d are fixed to the crate 100 after the cleats 1100 are fixed in place. In some embodiments, the cleats 1100, or at least the upper panels 1110 of the cleats functioning as lintels L are not fixed in place until after the battens 1300a-d are fixed to the second wall layers 320 of each wall 300a-d.

[0093] As discussed above with respect to the walls 300a-d and the back panel 700, the post and lintel assemblies may be aligned. Accordingly, when the frame battens 1300a-d are fixed to the second wall layer 320, they may be arranged such that the posts P of the fourth post and lintel assembly are adjacent the posts of the first, second, and third such assemblies, and such that the lintels L of the fourth post and lintel assembly are similarly adjacent the lintels of the corresponding assemblies.

[0094] Further, as shown, in some embodiments, a length of the frame battens 1300a, c forming the lintels L of the fourth post and lintel assembly correspond to a length of the second wall panel 320 of the corresponding wall 300a, c. In contrast, the length of the frame battens 1300b, d corresponding to the posts P may correspond to a length of the second wall panel 320 of the corresponding wall 300b, d less twice a width of the corresponding cleat panels 1110, 1120. The width of the frame battens 1300a-d may then correspond to the width of the cleat panels 1110, 1120, such that the frame battens 1300b, d forming the posts P can fold outwards past the corresponding cleats 1100 when in the open configuration.

[0095] FIG. 15 shows the partially assembled shipping crate 100 of FIG. 14 with a cover 1500 inserted. Typically, the cover 1500 is a lid panel, and the lid panel rests on the sides of the first wall layer 310 of each corresponding wall 300a-d. Accordingly, when in the closed configuration, as shown in FIG. 16, the first face 1310 of each of the frame battens 1300a-d rests on an outer face of the lid panel 1500, which is then flush with the sides of the second wall layer 320 of each wall. As such, the lid panel 1500 is sandwiched between the first wall layer 310 and the frame battens 1300a-d and is bounded by the second wall layer 320.

[0096] FIG. 16 shows a handle 1600 of an assembled shipping crate 100 in accordance with this disclosure. As shown, the handle 1600 may be fixed to an outer surface of at least one of the walls 300a-d and may abut a corresponding corner cleat 1100. It is further noted that while the handle 1600 is shown abutting the corner cleat 1100, in some embodiments, such as in larger crates, the handles may be fastened at a standard or otherwise convenient location, such as a standard height of 20 inches from a bottom of the crate.

[0097] FIG. 17 shows skids 1700 of an assembled shipping crate in accordance with this disclosure. In some embodiments, one of the plurality of walls 300c is defined as a bottom panel, and skids 1700 may be fixed to an outer surface of the bottom panel. As shown, two skids 1700 may be applied, and each of the two skids may be located adjacent to and abutting a corresponding corner cleat 1100.

[0098] In some embodiments, the handles 1600 and the skids 1700 may be fixed to the crate 100 using non-recyclable components, such as metal staples or the like. This may provide additional stability for the crate 100 while more securely fixing such structural components to the crate. Further, because the handles 1600 and skids 1700 are easily accessible, such components may be detached from the crate 100 such that the non-recyclable components can easily be removed and disposed of separately prior to recycling the remainder of the crate 100.

[0099] FIG. 18 shows a front view of an assembled shipping crate 100 in an unsealed configuration. Once fully assembled, the shipping crate may be sealed with tape, resulting in the configuration shown in FIG. 1.

[0100] In some embodiments, each joint of the shipping crate 100 may be glued prior to assembly and taped following assembly. This is shown, for example, in FIG. 6 above, where a bead of glue 600 is applied to the unassembled joint and tape 610 is positioned but not yet fixed in place.

[0101] FIGS. 19 and 20 show the use of a jig 1900 to properly locate the layers 310, 320 of the walls 300a-d of the shipping crate 100 of FIG. 1.

[0102] Generally, the shipping crate 100 described herein may be assembled by first preparing a plurality of walls 300a-d. For each of the walls, a first wall layer 310 and a second wall layer 320 is prepared. Each of the layers 310, 320 are formed from a rigid material, and the first wall layer has a width, length, sides 330, and a first thickness 340.

[0103] The second wall layer 320 is then sized for each of the plurality of walls 300 such that it has a width larger than the width of the first wall layer 310 by twice the first thickness 340 and a length larger than the first wall layer by twice the first thickness.

[0104] The first wall layer 310 is then assembled with the second wall layer 320 such that the second layer extends past each side 330 of the first wall layer by the first thickness 340.

[0105] A first back panel layer 710 is similarly prepared having sides and a thickness, with the thickness being substantially similar to the first thickness 340. An at least partial second back panel layer 720a-d is then applied to the first back panel layer 710 so as to form the back panel 700. When assembled, the second back panel layer 720a-d is positioned so as to extend past each side of the first back panel layer 710 by the first thickness 740.

[0106] The shipping crate 100 is then further assembled by assembling the plurality of walls 300a-d such that the first wall layer 310 of each of the walls forms a first post and lintel assembly and the second wall layer 320 of each of the plurality of walls forms a second post and lintel assembly.

[0107] The back panel 700 is then located such that the first back panel layer 710 rests on the sides 330 of the first wall layer 310 of each of the plurality of walls 300a-d and the second back panel layer rets on sides of the second wall layer 320 of the plurality of walls.

[0108] In some embodiments, after sizing the second wall layer 320 for each of the walls 300a-d, the first wall layer 310 is positioned relative to the second wall layer 320 using the jig 1900 shown in FIG. 19. As such, the wall layers are properly located while assembling the layers.

[0109] As discussed above, in some embodiments, prior to assembling the plurality of walls 300a-d, a bead of glue 600 is applied to each joint, and after assembling the plurality of walls, each joint is taped 610.

[0110] While the present invention has been described at some length and with some particularity with respect to the several described embodiments, it is not intended that it should be limited to any such particulars or embodiments or any particular embodiment, but it is to be construed with references to the appended claims so as to provide the broadest possible interpretation of such claims in view of the prior art and, therefore, to effectively encompass the intended scope of the invention. Furthermore, the foregoing describes the invention in terms of embodiments foreseen by the inventor for which an enabling description was available, notwithstanding that insubstantial modifications of the invention, not presently foreseen, may nonetheless represent equivalents thereto.
