Abstract

A composite container having a paperboard hollow body with top and bottom open ends. The body is formed by a sidewall with inner and outer surfaces. The composite container includes a body liner extending peripherally about the inner surface of the body and a base connectable to the bottom open end of the hollow body. The base includes a sidewall sized and shaped to fit snugly within the bottom open end of the body. The sidewall is permanently coupled to a bottom portion of the liner. The composite container also includes a collar connectable to the top open end of the hollow body. The collar has a peripheral portion that abuts the top open end and an inner circumferential flange sized and shaped to fit snugly within the top open end of the body. The inner circumferential flange is permanently coupled to a top portion of the liner. The peripheral portion has regions of weakened strength so that the section of the peripheral portion that abuts the top open end can be removed, thereby allowing a user to rapidly remove the coupled collar, liner and base from the hollow body.

Claims

1. A composite container comprising:

a paperboard hollow body having top and bottom open ends, the body formed by a sidewall having inner and outer surfaces,

a sidewall liner extending peripherally about the inner surface of the body forming a lined body, the sidewall liner is temporarily bonded to the body;

a base removably connectable to the bottom open end of the lined body, the base comprises a peripheral portion that abuts the bottom end of the lined body and a sidewall that fits in the bottom open end of the lined body, the sidewall of the base is bonded to a bottom portion of the sidewall liner, and

a collar removably connectable to the top open end of the body, the collar comprises a peripheral portion that abuts the top open end of the body and an inner circumferential flange that fits in the top open end of the body, the inner circumferential flange is bonded to a top portion of the sidewall liner,

thereby allowing disconnection of the bonded base, the sidewall liner and the collar from the body.

2. The composite container of claim 1, wherein the peripheral portion of the collar comprises regions of weakened strength so that a section of the peripheral portion that abuts the top open end can be removed, thereby allowing the bonded collar, the sidewall liner and the base to be more easily removed from the hollow body.

3. The composite container of claim 1, wherein the base comprises regions of weakened strength so that the portion of the base that abuts the bottom end of the body can be removed, thereby allowing the bonded base, the sidewall liner and the collar from the hollow body.

4. The composite container of claim 1 further comprising a bottom liner bonded to the base and the sidewall liner forming a hermetically sealed cavity.

5. The composite container of claim 1, wherein the collar further comprises an outer flange.

6. The composite container of claim 5, wherein the inner circumferential flange, the peripheral portion and the outer flange form a U-shaped cross-section that clamps the top open end of the hollow body.

7. The composite container of claim 1, wherein the inner circumferential flange has a circumferential ridge.

8. The composite container of claim 1 further comprising a bottom liner bonded to the framing element and the sidewall liner creating a hermetically sealed cavity.

9. The composite container of claim 1 further comprises a top liner bonded to the collar.

10. The composite container of claim 1, wherein the collar comprises a U-shape cross-section that frictionally couples the top open end of the lined body to the collar.

11. The composite container of claim 1 further comprises a lid.

12. The composite container of claim 1, wherein the collar is funnel shaped.

13. The composite container of claim 1, wherein the circumferential flange comprises threads.

14. A composite container comprising:

a paperboard hollow body having top and bottom open ends, the body formed by a sidewall having inner and outer surfaces,

a sidewall liner extending peripherally about the inner surface of the body forming a lined body, the sidewall liner is temporarily bonded to the body;

a base connectable to the bottom open end of the lined body, the base comprises a peripheral portion that abuts the bottom end of the lined body and a sidewall that fits in the bottom open end of the lined body, the sidewall of the base is bonded to a bottom portion of the liner, and

a collar connectable to the top open end of the body, the collar comprises a peripheral portion that abuts the top open end of the body and an inner circumferential flange that fits in the top open end of the body, the inner circumferential flange is bonded to a top portion of the liner.

15. The composite container of claim 14, wherein the collar further comprises an outer flange.

16. The composite container of claim 14, wherein the inner circumferential flange, the peripheral portion and the outer flange form a U-shaped cross-section that clamps the top open end of the hollow body.

17. The composite container of claim 14, wherein the inner circumferential flange has a circumferential ridge.

18. The composite container of claim 14 further comprising a bottom liner bonded to the framing element and the sidewall liner creating a hermetically sealed cavity.

19. The composite container of claim 14 further comprises a top liner bonded to the collar.

20. The composite container of claim 14, wherein the collar comprises a U-shape cross-section that frictionally couples the top open end of the lined body to the collar.

21. The composite container of claim 14 further comprises a lid.

22. The composite container of claim 14, wherein the collar is funnel shaped.

23. The composite container of claim 14, wherein the circumferential flange comprises threads.
