Abstract

A collapsible container includes a plurality of wall panels, wherein each wall panel is connected to each adjacent wall panel at a hinged connection. The wall panels are arranged so as to articulate at the hinged connections between a collapsed position and an expanded position defining a bottom wall and a plurality of side walls extending upwardly from the bottom wall. The collapsible container also includes an anti-fold lock that is disposed proximate to a hinged connection between first and second adjacent side walls. The first side wall includes at least two wall panels defining a diagonal hinge extending substantially between diagonally opposite corners of the side wall and the anti-fold lock is articulable into a locked position across the diagonal hinge.

Claims

1. A collapsible container, comprising:

a plurality of resilient wall panels, each wall panel connected to each adjacent wall panel at a hinged connection, wherein the wall panels are arranged so as to articulate at the hinged connections between a collapsed position and an expanded position, wherein in the expanded position the wall panels define a bottom wall, four side walls extending upwardly from a periphery of the bottom wall, and an opening opposite the bottom wall into an interior of the container, the first and third side walls spaced apart and facing each other and connected to each of the second and fourth side walls, and

wherein each of the bottom wall, the first side wall, and the third side wall comprises two of the resilient wall panels connected by a diagonal hinge extending to diagonally opposite corners of the respective wall; and

an anti-fold lock disposed on the exterior of the container proximate to the hinged connection between the first and second side walls, wherein the anti-fold lock articulates into a locked position across the diagonal hinge of the first side wall when the container is in the expanded position.

2. The collapsible container of claim 1, wherein the hinged connection between the first and second side walls is an arched hinge.

3. The collapsible container of claim 1, wherein the anti-fold lock in the locked position secures the diagonal hinge against folding inwardly.

4. The collapsible container of claim 1, wherein the anti-fold lock includes a resilient tab extending from the hinged connection.

5. The collapsible container of claim 4, wherein the tab is disposed proximate to the diagonal hinge at an upper portion of the collapsible container in the expanded position.

6. The collapsible container of claim 4, wherein the anti-fold lock includes a first connector disposed on the tab that is adapted to engage with a second connector disposed on the first side wall when the anti-fold lock is in the locked position across the diagonal hinge.

7. The collapsible container of claim 6, wherein the first connector comprises a tongue and the second connector includes a groove, and wherein the tongue resiliently snap-fits into the groove.

8. The collapsible container of claim 6, wherein the anti-fold lock is articulable into an unlocked position adjacent the second side wall, and wherein the anti-fold lock includes a third connector disposed on a side of the tab opposite the first connector that is adapted to engage a fourth connector disposed on the second wall when the anti-fold lock is in the unlocked position.

9. The collapsible container of claim 6, wherein the anti-fold lock is articulable into an unlocked position adjacent the second side wall, and wherein the anti-fold lock frictionally engages a bracket disposed on the container in the unlocked position.

10. The collapsible container of claim 1, further comprising a second anti-fold lock disposed proximate to the hinged connection between the third and fourth side walls, wherein the second anti-fold lock is articulable into a locked position across the diagonal hinge of the third side wall.

11. A collapsible container, comprising:

a plurality of wall panels, each wall panel connected to each adjacent wall panel at a hinged connection, wherein the wall panels are arranged so as to articulate at the hinged connections between a collapsed position and an expanded position, wherein in the expanded position, the wall panels define a bottom wall and first, second, third, and fourth side walls extending upwardly from a periphery of the bottom wall, wherein each of the bottom wall, the first side wall, and the third sidewall comprise two of the wall panels connected by a diagonal hinge extending to opposite diagonal corners of the respective wall; and

an anti-fold lock hingedly connected to a position proximate a hinged connection between the first and second side walls, wherein the anti-fold lock is articulable between a first position and a second position, and wherein the anti-fold lock releasably engages the first side wall in the first position and releasably engages the second side wall in the second position.

12. The collapsible container of claim 11, wherein the hinged connections between the adjacent side walls are arched hinges.

13. The collapsible container of claim 11, wherein the anti-fold lock engages the first side wall across the diagonal hinge in the first position.

14. The collapsible container of claim 13, wherein the anti-fold lock includes a resilient tab extending from the hinged connection, and wherein the tab is disposed proximate to the diagonal hinge proximate an upper portion of the collapsible container in the expanded position.

15. The collapsible container of claim 14, wherein the anti-fold lock includes a first connector disposed on the tab that is adapted to engage with a second connector disposed on the first side wall in the first position.

16. The collapsible container of claim 15, wherein the anti-fold lock includes a third connector disposed on a side of the tab opposite the first connector that is adapted to engage a fourth connector disposed on the second side wall in the second position.

17. The collapsible container of claim 15, wherein the anti-fold lock frictionally engages a bracket disposed on the container in the second position.
