Abstract

A container for holding at least one article includes a body having a front wall, a back wall, and at least one side wall extending at least partially around an interior of the container, a lid repositionable between a closed position at least partially overlying the body and an open position at least partially raised away from the body, the lid comprising a lid panel and a lid flange extending upwardly from the lid panel to at least partially form a lid recess, a reinforcement member at least partially received in the lid recess, and a closed bottom comprising a bottom panel attached to a portion of the body.

First claim

What is claimed is:

1. A container for holding at least one article, the container comprising:
a body comprising a front wall, a back wall, and at least one side wall extending at least partially around an interior of the container;
a lid repositionable between a closed position at least partially overlying the body and an open position at least partially raised away from the body, the lid comprising a lid panel and a lid flange extending upwardly from the lid panel to at least partially form a lid recess;
a reinforcement member at least partially received in the lid recess; and
a closed bottom comprising a bottom panel attached to a portion of the body.

2. The container of claim 1 , wherein the reinforcement member comprises pulp fibers.

3. The container of claim 2 , wherein the reinforcement member comprises molded pulp fibers.

4. The container of claim 3 , wherein the reinforcement member is molded so as to have a density within the range of from about 0.2 kg/dm 3 to about 1.5 kg/dm 3 .

5. The container of claim 2 , wherein the reinforcement member comprises a central portion and at least one wall extending upwardly from the central portion along the lid flange.

6. The container of claim 5 , wherein the at least one wall of the reinforcement member comprises a first vertical wall and a second vertical wall, and the reinforcement member comprises an intermediate flange extending from the first vertical wall to the second vertical wall.

7. The container of claim 6 , wherein an outer rim extends away from the second vertical wall to at least partially overlie a top edge of the lid.

8. The container of claim 5 , wherein the reinforcement member is a first reinforcement member at least partially received in the lid recess, wherein a bottom recess of the container is at least partially formed between the bottom panel and a bottom flange extending away from the bottom panel, and the container further comprises a second reinforcement member at least partially received in the bottom recess.

9. The container of claim 8 , wherein the second reinforcement member comprises molded pulp fibers.

10. The container of claim 9 , wherein the second reinforcement member comprises a central portion and at least one wall extending downwardly from the central portion along the bottom flange.

11. The container of claim 5 , wherein the lid flange is at least partially separable from and at least foldably connected to the body at a line of weakening.

12. The container of claim 11 , wherein the container further comprises at least one barrier member attached to the body in the interior of the container.

13. The container of claim 12 , wherein the at least one barrier member comprises a pull tab and at least one tear region at least partially separable from the remainder of the at least one barrier member to facilitate access to the interior of the container.

14. A combination of blanks for forming a container for holding at least one article, the combination of blanks comprising:
a body blank comprising a body forming portion for at least partially forming a body with a front wall, a back wall, and at least one side wall extending at least partially around an interior of the container formed from the combination of blanks;
a lid blank for at least partially forming a lid repositionable between a closed position at least partially overlying the body formed from the combination of blanks when the container is formed from the combination of blanks and an open position at least partially raised away from the body formed from the combination of blanks when the container is formed from the combination of blanks, the lid blank comprising a central portion and a marginal portion for at least partially forming a lid panel and a lid flange extending upwardly from the lid panel to at least partially form a lid recess when the container is formed from the combination of blanks;
a reinforcement blank for forming a reinforcement member for being at least partially received in the lid recess when the container is formed from the combination of blanks; and
a bottom blank for forming a bottom panel for being attached to a portion of the body formed from the body blank when the container is formed from the combination of blanks.

15. The combination of blanks of claim 14 , wherein the reinforcement blank comprises pulp fibers.

16. The combination of blanks of claim 15 , wherein the reinforcement blank is for being molded when the container is formed from the combination of blanks.

17. The combination of blanks of claim 16 , wherein the reinforcement member is for being molded so as to have a density within the range of from about 0.2 kg/dm 3 to about 1.5 kg/dm 3 when the container is formed from the combination of blanks.

18. The combination of blanks of claim 15 , wherein the reinforcement blank comprises a central portion and a marginal portion for forming least one wall extending upwardly from the central portion along the lid flange when the container is formed from the combination of blanks.

19. The combination of blanks of claim 18 , wherein the reinforcement blank is a first reinforcement blank for being at least partially received in the lid recess when the container is formed from the combination of blanks, wherein the bottom blank is for at least partially forming a bottom recess of the container formed from the combination of blanks between the bottom panel and a bottom flange extending away from the bottom panel when the container is formed from the combination of blanks, and the combination of blanks further comprises a second reinforcement blank for being at least partially received in the bottom recess when the container is formed from the combination of blanks.

20. The combination of blanks of claim 19 , wherein the second reinforcement blank comprises pulp fibers.

21. The combination of blanks of claim 20 , wherein the second reinforcement blank comprises a central portion and a marginal portion for forming at least one wall extending downwardly from the central portion along the bottom flange of the container when the container is formed from the combination of blanks.

22. The combination of blanks of claim 18 , wherein the body blank comprises a lid forming portion for at least partially forming the lid flange when the container is formed from the combination of blanks, the lid forming portion of the body blank is at least partially separable from and at least foldably connected to the body forming portion of the body blank at a line of weakening.

23. The combination of blanks of claim 22 , wherein the container further comprises at least one barrier blank for being attached to the body formed from the combination of blanks in the interior of the container formed from the combination of blanks.

24. The combination of blanks of claim 23 , wherein the at least one barrier blank comprises a pull tab and at least one tear region at least partially separable from the remainder of the at least one barrier blank to facilitate access to the interior of the container formed from the combination of blanks.

25. A method of forming a container for holding at least one article, the method comprising:
obtaining a body blank comprising a body forming portion;
obtaining a lid blank comprising a central portion and a marginal portion;
obtaining a reinforcement blank;
obtaining a bottom blank;
positioning the body forming portion of the body blank to form
