DETAILED DESCRIPTION OF THE INVENTION

[0017] FIG. 1A-B show views 100 and 109 a corner coupler for building a modular container. The front portion 101 of the corner coupler has a finished or rounded face 108 while the back portion 101′ of the corner couple has two matched continuous elongated channels 105 and 107. Between the two matched continuous elongated channels 105 and 107 there is and elongated tongue feature 106 that extends along the length of the back portion 101′ of the corner coupler. Corner couplers of the present invention are formed from any suitable materials including, but not limited to, plastics or polymers, composite materials, metals and combination thereof.

[0018] FIG. 2 shows an assembled corner section 200 of a modular container using the corner coupler shown in FIG. 1. Two adjacent side panels 201 and 203 of a modular container have elongated piping support structures 205 and 205′. The elongated piping support structures 205 and 205′ are attached to edges of the adjacent side panels 201 and 203 through any suitable means including elongated tab structures 207 and 207′ that are glued or sewn between portions of the adjacent side panels 210 and 203. Alternatively, the elongated tab structures 207 and 207′ are attached to the adjacent side panels 201 and 203 using any suitable means including, but not limited to, screws staples and clamp features. Preferability, the elongated piping support structures 205 and 205′ are co-molded onto the side edges of the side panels 201 and 203 when the side panels 201 and 203 are formed or made. The elongated piping support structures 205 and 205′ are formed from any suitable materials including, but not limited to, plastics or polymers, composite materials, metals and combination thereof.

[0019] In operation the elongated piping support structures 205 and 205′ are fitted into and pushed into the two matched continuous elongated channels 105 and 107, such that the back portion 101′ of the corner coupler forms an interior corner of the modular container and the front portion 101 of the corner coupler forms an exterior corner of the modular container.

[0020] FIG. 3 is a perspective view of an partially assembled modular container 300 using corner couplers, in accordance with the embodiments of the invention. The modular container 300 preferably includes a container body that includes a bottom panel 310 and four side panels 303, 305, 307 and 309 that are hingably and flexibly attached to four edges of the bottom panel 310. The bottom panel 310 and the side panels 303, 305, 307 and 309 of the modular container 300 are formed from the same materials or different materials. Suitable materials to form the bottom panel 310 and the side panels 303, 305, 307 and 309 include, but are not limited to plastics or polymers, woven materials and cloth (with or without internal support structures), metals and composite materials.

[0021] In operation, the modular container 300 is formed by sliding elongated piping support structures 315 and 317 on adjacent side panels 305 and 309 into two matched elongated channels 105 and 107 (FIGS. 1A-B and FIG. 2) of a corner coupler 310′, such as described with reference to FIG. 2 above. There are, for example, four such corner couplers 301, 310′ 301″ and 101″ that form the four corners of a fully assembled modular container.

[0022] FIG. 4 shows an exploded view of a modular container 400 with corner couplers 421, 421′ and 421″, side panels 403, 405, 407 and 409, a bottom panel 401, a top panel or cover 411 and a sectional insert or compartment divider 413. The corner couplers 421, 421′ and 421″ preferably have elongated channels 105 and 107 and an elongated tongue feature 106, such as described with reference to FIGS. 1A-B and FIG. 2.

[0023] The modular container 400 can also include a bottom panel or side panel inserts (not shown) that fit into an assembled modular container or are held within pocket or sleeves on the bottom panel 401 and/or side panels 403, 405, 407 and 409 to add rigidity to the assembled modular container 400. In further embodiments of the invention the modular container 400 includes dividers 413 that fit into the assembled modular container 400 and attaches to walls of the bottom panel 401 and/or side panels 403, 405, 407 and 409 through attachment features including, but not limited to, two part snap features, hook and loop fabric and matted tongue and grove-type slotted features or combinations thereof. The side panels 403, 405, 407 and 409, a bottom panel 401, a top panel or cover 411 are formed from the same materials or different materials. Suitable materials to form the side panels 403, 405, 407 and 409, a bottom panel 401, a top panel or cover 411 include, but are not limited to plastics or polymers, woven materials and cloth (with or without internal support structures), metals and composite materials.

[0024] The top panel 411 fits over a container cavity of the assembled modular container 400 and the side panels 403, 405, 407 and 409 and be detachably secured through portions of the corner couplers 421, 421′ and 421″. Any of the side panels 403, 405, 407 and 409 and/or top panel 411 can include handle features 431 on the outer surfaces for porting the assembled modular container 400. As described above, the corner couplers 421, 421′ and 421″ slide up and down, as indicated by the arrow 451 along edges 423 and 429 of adjacent side panels 403 and 409. The along edges 423 and 429 of adjacent side panels 403 and 409 preferably have elongated piping support structures that fit into the elongated channels on the corner couplers 421, 421′ and 421″, such as described above.

[0025] FIGS. 5A-D show a view 500 a corner coupler 501 with a two elongated channels 505 and 507, an elongated tongue feature 506, an open receiving end 511 and a closed finished end 509 that is used to attached adjacent side panels of the modular container together through piping support structures. The corner coupler 501 preferably has a curved or rounded front portion 511. The two elongated channels 505 and 507 are formed between lip features 508 and 508′ and a elongated tongue feature 506. Within the two elongated channels 505 and 507 and near the closed finished end 509 of the corner coupler 510 there are stop features 513 and 513′. The stop features 513 and 513′ prevent the elongated piping support structures 205 and 205′ (FIG. 2) from being pushed any further into the two elongated channels 505 and 507 when assembling a modular container, such as described with reference to FIGS. 2-4. In this embodiment of the invention the closed finished end 509 will protrude up from top edges of an assembles modular container and be used to help support stacking of additional containers or can be used to secure to a top panel or lid feature that fits over a container cavity of the assembled modular container. A top panel or lid feature can be secured to the corner couplers of the assembled modular container using any suitable attachment mechanism including, but not limited to, compression fittings, hook and loop fabric, magnets, straps, snap features and combinations thereof.

[0026] As described above a modular container is assembled by sliding elongated piping support structures attached to adjacent side panels into two elongated channels at the open receiving ends each of the corner couplers. The corner couples can locked or secured into the assembled position by, for example, compression, snap features, matched lock features on the corner couplers and the bottom panels, side panels and/or on the elongated piping support structures or by any other suitable method.

[0027] The elongated piping support structures and the matched elongated channels have been described herein as having round cross-sectional shapes, but other cross-sectional shapes are envisioned including, but not limited to, square, triangular, hexagonal and irregular cross-sectional shapes, as long as pipping support structures can be fitted into and secured within the matched elongated channels. And while matched elongated channels are described herein as being continuous sectionalized matched channels are also contemplated. Corner couples of the present invention are used to assemble rectangular modular containers but can be configured to assemble modular containers with other shapes including, triangular, hexagonal or irregular shapes.

[0028] The present invention has been described in terms of specific embodiments incorporating details to facilitate the understanding of the principles of construction and operation of the invention. As such, references herein to specific embodiments and details thereof are not intended to limit the scope of the claims appended hereto. It will be apparent to those skilled in the art that modifications can be made in the embodiments chosen for illustration without departing from the spirit and scope of the invention.
