Abstract

A transport container having a base and a plurality of side walls perpendicularly connected to form a container having an inner cavity. The side walls are formed of first and second wall panels. The first and second wall panels are hingedly connected so that the first or upper wall panels may fold down relative to the second or lower wall panels to collapse the transport container after use. The first and second wall panels are hingedly connected by an elongated flexible hinge. Edge portions of the first wall panels have coupling assemblies that are designed to selectively connect and disconnect adjacent first wall panels.

Claims

1. A transport container comprising:

a base;

a plurality of side walls extending from the base, the side walls being adjacent to each other at edges to form a container having an inner cavity, each of the side walls being formed of a first wall panel and a second wall panel connected to the first wall panel by a hinge, adjacent first wall panels being selectively connectable and disconnectable to each other at edges of the side walls to allow the first wall panels to fold down relative to the second wall panels thereby shortening the transport container;

wherein at least one of the second wall panels is slidably connected to adjacent second wall panels by edge connectors such that the side wall with the slidably connected second wall panel may be slid in a direction essentially perpendicular to the base for access to the inner cavity, the edge connectors preventing the adjacent second wall panels from pulling away from the slidably connected second wall panel in other directions.

2. The transport container of claim 1, wherein the edge connectors include essentially perpendicularly oriented U-shaped panel attachment elements, said U-shaped panel attachment elements forming wall channels, said wall channels of the perpendicularly oriented U-shaped panel attachment elements being sized to slidably receive edge portions of adjacent second wall panels to perpendicularly support adjacent second wall panels.

3. The transport container of claim 2, wherein the U-shaped panels attachment elements have attachment flanges, and wherein the slidably received edge portions have smaller width portions which mate with the attachment flanges to prevent the slidably received edge portions from pulling away from the edge connectors.

4. The transport container of claim 1, wherein the edge connectors are attached to the base and extend upwardly from the base between adjacent second wall panels.

5. A transport container comprising:

a base;

a plurality of side walls extending from the base, the side walls being adjacent to each other to form a container having an open top and an inner cavity, each of the side walls being formed of a first wall panel and a second wall panel hingedly connected thereto by a hinge which seals against ambient air flow between the first wall panel and the second wall panel, the second wall panels being sealably connectable to the base and to each other; and

cooperating edgeloks attached at edges of each of the first wall panels, the cooperating edgeloks being selectively connectable and disconnectable to allow the first wall panels to fold down relative to the second wall panels, the cooperating edgeloks extending the entire height of the first wall panels, the cooperating edgeloks being formed of plastic material and having a plurality of surfaces which mate to seal against air flow between adjacent first wall panels.

6. The transport container of claim 5 wherein each of the cooperating edgeloks comprises:

a wall attachment portion attached to an edge of a first wall panel;

a latch extension moveably supported by the wall attachment portions;

an opposing wall attachment portion attached to an adjacent edge of an adjacent first wall panel for attaching adjacent edges of adjacent first wall panels together; and

a latch channel defined in the adjacent edge of the adjacent first wall panel, wherein the latch extension can be moved to extend into the latch channel to selectively connect the wall attachment portion to the opposing wall attachment portion and moved out of the latch channel to allow disconnection of the wall attachment portion to the opposing wall attachment portion.

7. The transport container of claim 6 wherein the wall attachment portion comprises a U-shaped member with an extending edge portion, and wherein the opposing wall attachment portion comprises a U-shaped member with an extending edge portion, the U-shaped member of the opposing wall attachment portion being sized to receive the extending edge portion of the wall attachment portion with a slight interference fit, the extending edge portion of the opposing wall attachment portion being sized to be received with the U-shaped member of the wall attachment portion with a slight interference fit.

8. The transport container of claim 5 wherein the hinge connecting the first and second wall panels is elongated to extend from edge to edge across the entire width of the side wall.

9. The transport container of claim 5, further comprising:

a cover for closing and sealing the open top of the container.

10. The transport container of claim 9, wherein the cover comprises:

a relatively rigid portion sized smaller than the open top to the inner cavity of the container; and

a flexible sealwing extending about an outer perimeter of the rigid portion, said rigid portion and flexible sealwing being dimensioned slightly larger than the open top for providing a tight seal between the sidewalls of the container and the cover of the container.

11. The transport container of claim 5, wherein the base includes a drain hole for draining liquid from an inner cavity of the container, and wherein the drain hole includes a check valve to seal the drain hole.

12. The transport container of claim 11 wherein the base includes a plurality of legs extending essentially perpendicularly downwardly therefrom, and wherein the drain hole extends through a leg.

13. The transport container of claim 5 wherein the wall panels and base are formed of a hollow core and filled with an insulating material.

14. The transport container of claim 5, wherein the hinge comprises

a first contact extension connected to the first wall panel;

a second contact extension connected to the second wall panel; and

an elongated flexible portion having a plurality of fold over segments extending between the first contact extension and the second contact extension.

15. The transport container of claim 5 wherein the hinge is formed of an elastomer material.

16. A transport container comprising:

a base;

a plurality of side walls extending upward from the base, the side walls being adjacent to each other at edges to form a container having an inner cavity, each of the side walls being formed of a lower panel contacting the base and an upper panel connected to the lower panel by a hinge to allow the upper panel to fold down relative to the lower panel;

wherein the lower panel of at least one of the side walls is slidably connected to the lower panels of adjacent side walls by edge connectors, such that the side wall with the slidably connected lower panel may be slid upward from the base for access to the inner cavity, the edge connectors preventing the lower panels of adjacent side walls from pulling away from the slidably connected lower panel in other directions.

17. The transport container of claim 16, wherein the edge connectors include essentially perpendicularly oriented U-shaped panel attachment elements, said U-shaped panel attachment elements forming wall channels, said wall channels of the perpendicularly oriented U-shaped panel attachment elements being sized to slidably receive edge portions of adjacent second wall panels to perpendicularly support adjacent second wall panels.

18. The transport container of claim 17, wherein the U-shaped panels attachment elements have attachment flanges, and wherein the slidably received edge portions have smaller width portions which mate with the attachment flanges to prevent the slidably received edge portions from pulling away from the edge connectors.

19. The transport container of claim 16, wherein the edge connectors are attached to the base and extend upwardly from the base between adjacent second wall panels.
