Abstract

The present disclosure, in one embodiment, relates to a packaging assembly for holding liquids, viscous material, or particulate material. The packaging assembly includes a carton having side and bottom walls. The packaging assembly also includes a self-supporting plastic liner that fits inside of the carton for containing liquids, viscous material, or particulate material. The liner has either a substantially circular or substantially oval cylindrical side wall, a closed bottom end characterized by a bottom wall formed integral with said side wall, and an open top end having an outwardly-projecting rim. The rim has a radially-extending flange portion, and a dependent skirt portion, wherein when the self-supporting plastic liner is inside of the carton, the radially extending flange portion supports the liner on at least a portion of the carton. A lidding material is provided to seal the plastic liner.

Claims

1. A packaging assembly for holding liquids, viscous material, or particulate material comprising:

a cardboard carton having carton side walls and a carton bottom wall, the carton side walls having upper portions extending from a top of the carton and defining a carton exterior, the carton side walls extending from the upper portions to a bottom of the carton;

a self-supporting plastic liner having a liner side wall that fits inside of the carton, the plastic liner being self supported to include an outwardly-projecting rim that comprises a radially-extending flange portion and a skirt portion dependent therefrom, wherein the self-supporting plastic liner is configured for containing liquids, viscous material, or particulate material, said liner having a closed bottom end characterized by a liner bottom wall formed integral with said liner side wall, and an open top end having the outwardly-projecting rim, and the dependent skirt portion at least partially extending over said upper portions of the carton side walls, wherein when the self-supporting plastic liner is inside of the carton, the radially extending flange portion supports the liner on the upper portions of the carton side walls; and

a lidding material configured to seal the plastic liner.

2. A packaging assembly according to claim 1, further comprising a carton lid fitting over the liner.

3. A packaging assembly according to claim 1, wherein the carton comprises inner side walls for supporting the radially extending flange portion.

4. A packaging assembly according to claim 1, wherein the plastic liner is made of polyethylene.

5. A packaging assembly according to claim 1, wherein the plastic liner rests on and is supported by the carton bottom wall.

6. A packaging assembly according to claim 1, wherein the lidding material is detachably sealed to the plastic liner to seal the interior of the plastic liner.

7. A packaging assembly of claim 1, wherein the liner is semi-rigid.

8. A packaging assembly of claim 1, wherein the liner side wall and the rim portion are of unitary construction.

9. A packaging assembly of claim 1, wherein the carton side walls together form a substantially rectangular shaped cross-section.

10. A packaging assembly of claim 1, wherein the carton side walls extend vertically straight substantially continuously from the top of the carton to the bottom of the carton.

11. A packaging assembly of claim 1, wherein the rim has a vertical height, and wherein the upper portion of the carton side walls extend the entire vertical height of the rim.

12. A packaging assembly of claim 1, wherein the carton sidewalls are vertical, and wherein the upper portions extend from the top of the carton and define a carton exterior that is substantially vertically straight.

13. A packaging assembly for holding liquids, viscous material, or particulate material comprising:

a carton having carton side walls and a carton bottom wall, the carton side walls having upper portions extending from a top of the carton and defining a carton exterior that is substantially vertically straight, the carton side walls extending from the upper portions to a bottom of the carton;

a self-supporting plastic liner having a liner side wall that fits inside of the carton, the plastic liner being self supported to include an outwardly-projecting rim that comprises a radially-extending flange portion and a skirt portion dependent therefrom, wherein the self-supporting plastic liner is configured for containing liquids, viscous material, or particulate material, said liner having a closed bottom end characterized by a liner bottom wall formed integral with said liner side wall, and an open top end having the outwardly-projecting rim, and the dependent skirt portion at least partially extending over said upper portions of the carton side walls, wherein when the self-supporting plastic liner is inside of the carton, the radially extending flange portion supports the liner on the upper portions of the carton side walls, and wherein the rim has a vertical height and the upper portion of the carton side walls extend the entire vertical height of the rim; and

a lidding material configured to seal the plastic liner.

14. A packaging assembly according to claim 13, further comprising a carton lid fitting over the liner.

15. A packaging assembly according to claim 13, wherein the carton comprises inner side walls for supporting the radially extending flange portion.

16. A packaging assembly according to claim 13, wherein the plastic liner is made of polyethylene.

17. A packaging assembly according to claim 13, wherein the plastic liner rests on and is supported by the carton bottom wall.

18. A packaging assembly according to claim 13, wherein the lidding material is detachably sealed to the plastic liner to seal the interior of the plastic liner.

19. A packaging assembly of claim 13, wherein the liner is semi-rigid.

20. A packaging assembly of claim 13, wherein the liner side wall and the rim portion are of unitary construction.

21. A packaging assembly of claim 13, wherein the carton side walls together form a substantially rectangular shaped cross-section.

22. A packaging assembly of claim 13, wherein the carton side walls extend vertically straight substantially continuously from the top of the carton to the bottom of the carton.

23. A packaging assembly of claim 13, wherein the carton is a cardboard carton.

24. A packaging assembly of claim 13, wherein the carton sidewalls are vertical.
