Abstract

A blank of foldable sheet material for forming a container is provided. The blank includes a top panel, a front tuck flap extending from a front edge of the top panel, and a top side panel extending from a side edge of the top panel. The blank also includes a bottom panel, a front panel extending from a front edge of the bottom panel, and a corner portion. The corner portion includes a minor diagonal panel extending and a major diagonal panel. The corner portion also includes a corner panel hingedly connected to the minor and major diagonal panels. The front panel is configured to engage the front tuck flap to at least partially define a first releasably secure closure of the container, and the top side panel includes a front edge configured to engage the minor diagonal panel to at least partially define a second releasably secure closure of the container.

First claim

The invention claimed is:

1. A blank of foldable sheet material for forming a container, said blank comprising:
a top portion comprising a top panel, and a first top side panel extending from a first side edge of said top panel, the first top side panel having a front edge including a portion extending therefrom; and
a bottom portion comprising a bottom panel, a first bottom side panel extending from a first side edge of said bottom panel, a front panel extending from a front edge of said bottom panel, and
a corner portion comprising:
a first minor diagonal panel extending from a front edge of said first bottom side panel;
a first major diagonal panel extending from a first side edge of said front panel, said first major diagonal panel having a length greater than a length of said first minor diagonal panel; and
a first corner panel hingedly connected to said first minor and major diagonal panels, wherein said extending portion is configured to contact said first minor diagonal panel to at least partially define a first releasably secure closure of the container in the closed position.

2. The blank of claim 1 , wherein said extending portion is in a friction fit with said first minor diagonal panel when the blank is erected into a carton.

3. The blank of claim 1 , further comprising a front tuck flap extending from a front edge of said top panel, wherein said front panel is configured to engage said front tuck flap to at least partially define an additional releasably secure closure of the container in a closed position.

4. The blank of claim 1 , further comprising a front tuck flap which includes an offset edge, at least one of said front panel and said first major diagonal panel further comprises a notch, and said notch being configured to receive said offset edge when the container is formed to at least partially define the first releasably secure closure of the container in the closed position.

5. The blank of claim 1 , wherein the first top side panel has an arcuate cutout along its lower edge.

6. A container formed from a blank of foldable sheet material, said container comprising:
a top portion comprising a top panel hingedly connected to a first top side panel along a first side edge of said top panel, the first top side panel having a front edge including a portion extending therefrom; and
a bottom portion comprising a bottom panel, a first bottom side panel hingedly connected to a first side edge of said bottom panel, a front panel hingedly connected to a front edge of said bottom panel, and
a corner portion comprising:
a first minor diagonal panel extending from a front edge of said first bottom side panel;
a first major diagonal panel extending from a first side edge of said front panel, said first major diagonal panel having a length greater than a length of said first minor diagonal panel; and
a first corner panel hingedly connected to said first minor and major diagonal panels, said first corner panel overlapping and substantially parallel to said bottom panel, wherein said extending portion contacts said first minor diagonal panel to at least partially define a first releasably secure closure of the container.

7. The container of claim 6 , wherein said extending portion is configured to contact said first minor diagonal panel in a friction fit.

8. The container of claim 6 , further comprising a front tuck flap extending from a front edge of said top panel, wherein said front panel engages said front tuck flap to at least partially define an additional releasably secure closure of the container in a closed position.

9. The container of claim 8 , wherein said front tuck flap further comprises an offset edge, at least one of said front panel and said first major diagonal panel further comprises a notch, and said notch being configured to receive said offset edge when the container is formed to at least partially define the first releasably secure closure of the container in the closed position.

10. The blank of claim 6 , wherein the first top side panel has an arcuate cutout along its lower edge.

11. A blank of foldable sheet material for forming a container, said blank comprising:
a top portion comprising a top panel, a front tuck flap extending from a front edge of said top panel, and a first top side panel extending from a first side edge of said top panel;
a bottom portion comprising a bottom panel, a first bottom side panel extending from a first side edge of said bottom panel, a front panel extending from a front edge of said bottom panel, and
a corner portion comprising:
a first minor diagonal panel extending from a front edge of said first bottom side panel;
a first major diagonal panel extending from a first side edge of said front panel, said first major diagonal panel having a length greater than a length of said first minor diagonal panel; and
a first corner panel hingedly connected to said first minor and major diagonal panels,

wherein said front tuck flap further comprises an offset edge, at least one of said front panel and said first major diagonal panel further comprises a notch, and said notch being configured to be open along an upper edge of said at least one of the front panel and first major diagonal panel and to receive said offset edge when the container is formed to at least partially define a first releasably secure closure of the container in the closed position.

12. The blank of claim 11 , wherein the first top side panel comprises a front edge including a portion extending therefrom.

13. The blank of claim 12 , wherein said extending portion is configured to contact said first minor diagonal panel in a friction fit.

14. The blank of claim 11 , wherein the first top side panel has an arcuate cutout along its lower edge.

15. A container formed from a blank of foldable sheet material, said container comprising:
a top portion comprising a top panel hingedly connected to a front tuck flap along a front edge of said top panel and to a first top side panel along a first side edge of said top panel;
a bottom portion comprising a bottom panel, a first bottom side panel hingedly connected to a first side edge of said bottom panel, a front panel hingedly connected to a front edge of said bottom panel, and
a corner portion comprising:
a first minor diagonal panel extending from a front edge of said first bottom side panel;
a first major diagonal panel extending from a first side edge of said front panel, said first major diagonal panel having a length greater than a length of said first minor diagonal panel; and
a first corner panel hingedly connected to said first minor and major diagonal panels, said first corner panel overlapping and substantially parallel to said bottom panel,

wherein said front tuck flap further comprises an offset edge, at least one of said front panel and said first major diagonal panel at its upper edge further comprises a notch open to said upper edge, and said notch receives said offset edge to at least partially define a first releasably secure closure of the container in the closed position.

16. The container of claim 15 , wherein the first top side panel comprises a front edge including a portion extending therefrom.

17. The container of claim 16 , wherein said extending portion is configured to contact said first minor diagonal panel in a friction fit.

18. The blank of claim 15 , wherein the first top side panel has an arcuate cutout along its lower edge.

19. The blank of claim 1 , said extending portion configured to contact said first minor diago
