Abstract

A container for transporting meat, produce, and other goods contains a bottom wall, side walls, and end walls. The end walls include hinged platform structures movable between a closed position and an open position. The closed position enables stable stacking of multiple containers and the open position allows easy access to the interior of the container for loading and unloading. The hinged platforms further add stability to the container walls when in the closed position.

Claims

1. A container comprising:

a bottom panel;

first and second side panels extending upwardly from said bottom panel;

first and second end panels extending upwardly from said bottom panel;

first and second minor interior wall flaps foldingly connected to said first side panel, and extending generally perpendicularly to said bottom panel such that said first and second minor interior wall flaps are parallel to said first and second end panels;

third and fourth minor interior wall flaps foldingly connected to said second side panel, and extending generally perpendicularly to said bottom panel such that said third and fourth minor interior wall flaps are parallel to said first and second end panels;

a first hinged platform structure attached to said first end panel along a first hinge offset below a top of said first and third minor interior wall flaps, said first hinged platform structure being integral with said first end panel, said first hinged platform structure comprises a first top platform, a first end folding flap, and first and second side reinforcement flaps; and

a second hinged platform structure attached to said second end panel along a second hinge offset below a top of said second and fourth minor interior wall flaps, said second hinged platform structure being integral with said second end panel, said second hinged platform structure comprises a second top platform, a second end folding flap, and third and fourth side reinforcement flaps,

wherein said first hinged platform structure further comprises first and second minor platform panels, and said second hinged platform structure further comprises third and fourth minor platform panels, said first and second minor platform panels being below said first top platform and said third and fourth minor platform panels being below said second top platform, in surface-to-surface relationships

wherein the first minor platform panel, the second minor platform panel and the first top platform assist in forming a first top portion of the container, the first top portion of the container in the closed position being located opposite of the bottom panel,

wherein the third minor platform panel, the fourth minor platform panel and the second top platform assist in forming a second top portion of the container, the second top portion of the container in the closed position being located opposite of the bottom panel.

2. The container of claim 1, further comprising a first handhold below said first hinge in said first end panel and a second handhold below said second hinge in said second end panel.

3. The container of claim 1, wherein said first hinged platform structure comprises a rollover panel having rollover tabs positioned to fit into rollover tab receptacles.

4. The container of claim 1, wherein said container comprises corrugated fiberboard and said first and second side panels contain vertically corrugated fiberboard.

5. The container of claim 1, wherein said first and second hinged platforms are adapted to be moved to an open position such that said first and second hinged platforms are angled away from the inside of said container.

6. The container of claim 5, wherein said first and second hinged platforms each include a pair of cornered tabs positioned to receive a bottom of a stacked container.

7. A container comprising:

a bottom panel;

first and second side panels extending upwardly from said bottom panel;

first and second end panels extending upwardly from said bottom panel;

first and second minor interior wall flaps foldingly connected to said first side panel, and extending generally perpendicularly to said bottom panel such that said first and second minor interior wall flaps are parallel to said first and second end panels;

third and fourth minor interior wall flaps foldingly connected to said second side panel, and extending generally perpendicularly to said bottom panel such that said third and fourth minor interior wall flaps are parallel to said first and second end panels;

a first hinged platform structure attached to said first end panel along a first hinge offset below a top of said first and third minor interior wall flaps, said first hinged platform structure being integral with said first end panel, said first hinged platform structure comprising a first top platform, a first end folding flap, and first and second side reinforcement flaps; and

a second hinged platform structure attached to said second end panel along a second hinge offset below a top of said second and fourth minor interior wall flaps, said second hinged platform structure being integral with said second end panel, said second hinged platform structure comprises a second top platform, a second end folding flap, and third and fourth side reinforcement flaps,

wherein the interior surfaces of said first and second side reinforcement flaps are disposed on respective exterior surfaces of said first and second side panels and wherein the interior surfaces of said third and fourth side reinforcement flaps are disposed on respective exterior surfaces of said third and fourth side panels.

8. The container of claim 7, further comprising a first handhold below said first hinge in said first end panel and a second handhold below said second hinge in said second end panel.

9. The container of claim 7, wherein said first hinged platform structure comprises a rollover panel having rollover tabs positioned to fit into rollover tab receptacles.

10. The container of claim 7, wherein said container comprises corrugated fiberboard and said first and second side panels contain vertically corrugated fiberboard.

11. The container of claim 7, wherein said first and second hinged platforms are adapted to be moved to an open position such that said first and second hinged platforms are angled away from the inside of said container.

12. The container of claim 11, wherein said first and second hinged platforms each include a pair of cornered tabs positioned to receive a bottom of a stacked container.
