Abstract

The present invention provides a stackable open-top container for use in shipping, storing and retail display of produce and other articles. The produce container contains a bottom wall, two side walls and two end walls. The ledges of the side walls of the present invention contain opposed concave curved scores. The produce container is formed by folding the side walls to the outside to achieve structural rigidity. The produce container of the present invention provides for full graphical coverage on all visible surfaces by use of a one-piece blank that is color coated/printed on only one side.

Claims

1. A stackable produce container, comprising:

a bottom wall;

first and second opposing side walls, each of said first and second side walls including an inner side panel and an outer side panel hingedly connected to each other and said inner side panel is hingedly connected to said bottom wall;

first and second opposing end walls;

minor side flaps extending from opposing ends of each of said inner side panels;

a first set of minor end flaps hingedly connected to opposing ends of each of said end panels; and

a second set of minor end flaps hingedly connected to each of said first set of minor end flaps;

wherein said first set of minor end flaps and said minor side flaps create a diagonal corner structure.

2. The produce container of claim 1, further comprising adhesive between each of said minor side flaps and a respective minor end flap of the first set of minor end flaps.

3. The produce container of claim 1, wherein said inner side panel, said outer side panel, and said minor side flaps have vertical corrugations.

4. The produce container of claim 1, wherein said opposing end panels, said first set of minor end flaps, and said second set of minor end flaps have horizontal corrugations.

5. A stackable produce container, comprising:

a bottom wall;

first and second opposing end walls;

first and second opposing side walls, each of said first and second side walls including minor side flaps extending from opposing ends of each of said first and second side walls, said minor side flaps hingedly connected to opposing ends of each of said first and second side walls, wherein said minor side flaps reinforce corners of the container, each of said first and second side walls having an inner side panel and an outer side panel hingedly connected to each other, said inner side panel being hingedly connected to said bottom wall; and

a plurality of stacking tabs located on said outer side panels.

6. The produce container of claim 5, wherein said minor side flaps are hingedly connected to each of said inner side panels.

7. The produce container of claim 5, further comprising a plurality of stacking receptacles.

8. The produce container of claim 5, further comprising a first set of minor end flaps hingedgly connected to opposing ends of each of said end panels.

9. The produce container of claim 8, further comprising a second set of minor end flaps hingedly connected to each of said first set of minor end flaps.

10. The produce container of claim 9, wherein said second set of minor end flaps are adapted to connect to said first and second side walls.

11. The produce container of claim 9, wherein said first and second end walls, said first set of minor end flaps and said second set of minor end flaps have horizontal corrugations.

12. A stackable produce container, comprising:

a bottom wall;

first and second opposing end walls;

first and second opposing side walls, each of said first and second side walls including minor side flaps extending from opposing ends of each of said first and second side walls, said minor side flaps hingedly connected to opposing ends of each of said first and second side walls, wherein said minor side flaps reinforce corners of the container; and

a first set of minor end flaps hingedly connected to each of said opposing ends of each of said end panels, said first set of minor end flaps being further connected to said minor side flaps to create a diagonal corner structure.

13. The produce container of claim 12, further comprising adhesive between each of said minor side flaps and a respective minor end flap of the first set of minor end flaps.

14. The produce container of claim 12, wherein said first and second side walls and said minor side flaps have vertical corrugations.

15. The produce container of claim 12, wherein said first and second side walls and said minor side flaps have horizontal corrugations.

16. A one piece blank for forming a stackable produce container, comprising:

a central rectangular panel having a first pair of opposing edges and a second pair of opposing edges;

a first inner side panel hingedly connected to one of said first pair of opposing edges, said first inner side forming a first pair of stacking receptacles;

a second inner side panel hingedly connected to the other of said first pair of opposing edges, said second inner side panel forming a second pair of stacking receptacles;

a first outer side panel hingedly connected to said first inner side panel, said first outer side panel including a first pair of stacking tabs;

a second outer side panel hingedly connected to said second inner side panel, said second outer side panel including a second pair of stacking tabs;

a first end panel hingedly connected to one of said second pair of opposing edges;

a second end panel hingedly connected to one of said second pair of opposing edges;

minor side flaps extending from opposing ends of each of said inner side panels;

a first set of minor end flaps hingedly connected to opposing ends of each of said end panels; and

a second set of minor end flaps hingedly connected to opposing ends of said first set of minor end flaps;

wherein said first minor end flaps and said minor side flaps are adapted to create a diagonal structure when said blank is formed into said container.
