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 carton having side and bottom walls;

a self-supporting plastic liner that fits inside of the carton, and is for containing liquids, viscous material, or particulate material, said liner comprising a substantially circular or 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, said rim comprising 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; 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 lidding material is removeably affixed to the rim of the plastic liner once the plastic liner has been filled with liquid, viscous material, or particulate material.

5. A packaging assembly according to claim 1, further comprising a plastic lid comprising an inner portion and a rim, wherein the rim of the plastic lid is configured to fit snugly with the rim of the plastic liner.

6. A packaging assembly according to claim 5, wherein the plastic liner and plastic lid are made of recyclable high-density polyethylene.

7. A packaging assembly according to claim 5, wherein the plastic liner and plastic are made of recyclable linear low-density polyethylene.

8. A packaging assembly according to claim 5, wherein the rim of the plastic lid and the rim of the plastic liner are substantially C-shaped.

9. A packaging assembly according to claim 5, wherein the rim of the plastic lid makes a snap fit with the rim of the plastic liner, and wherein the plastic lid is removeably interlocking with the plastic liner.

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

11. A packaging assembly according to claim 1, wherein the carton and the carton lid are substantially square shaped in cross-section.

12. A packaging assembly according to claim 1, wherein the carton and the carton lid are substantially rectangular in cross-section.

13. A packaging assembly according to claim 1, wherein the bottom wall of the carton contains at least one plastic liner access point, whereby when a plastic liner is inside of the carton and resting on the bottom wall, the plastic liner may be pushed upward by contacting the liner through at least one plastic liner access point.

14. A packaging assembly according to claim 1, further comprising a pad that is placed inside of the carton and that rests against the bottom wall of the carton, and wherein the bottom wall of the carton contains at least one plastic liner access point, whereby when a plastic liner is inside of the carton and resting on the pad, the pad and the plastic liner may be pushed upward by contacting the pad through at least one plastic liner access point.

15. A packaging assembly according to claim 2, wherein the carton, the plastic liner, the lidding material, and the carton lid are all made of recyclable material.

16. A packaging assembly according to claim 1, wherein the lidding material is detachably affixed to the radially-extending flange of the plastic liner.

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

a carton having side, top, and bottom walls, and a carton lid near the top wall, the carton comprising a tear strip or perforation dividing the carton lid from the remainder of the carton; and

a self-supporting plastic liner inside of the carton for containing liquids, viscous material, or particulate material, said liner comprising a 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, said rim comprising a radially-extending flange portion, and a dependent skirt portion, wherein the radially extending flange portion supports the liner on at least a portion of the carton;

wherein separation along the tear strip or perforation allows the carton lid to at least partially open and expose the liner within the carton.

18. A packaging assembly according to claim 17, further comprising a lidding material configured to seal the plastic liner.

19. A packaging assembly according to claim 17, wherein the carton comprises inner side walls for supporting the radially extending flange portion.

20. A packaging assembly according to claim 17, further comprising a plastic lid comprising an inner portion and a rim, wherein the rim of the plastic lid is configured to fit snugly with the rim of the plastic liner.

21. A packaging assembly according to claim 17, wherein the carton is substantially square shaped in cross-section.

22. A packaging assembly according to claim 17, wherein the carton is substantially rectangular in cross-section.
