Abstract

A liner fastener arrangement for retaining a liner including bags with or without handles. The liner fasteners are retained relative to the container for providing removable liners.

Claims

1. A device for securing a flexible plastic liner around the rim of a container comprising;

generally upright side portions of the container and the side portions terminating in a substantially continuous rim portion;

a snap-type fastener comprising a cap member and protruding member extending outwardly from the side portions and capable of grasping and maintaining a portion of the mouth of said liner between the cap member and the protruding member, said snap-type fastener situated a sufficient distance below the rim of said container so as to work in cooperative association with the opposite external side of said container to increase the effective circumference of the mouth of said plastic liner as the liner is pulled against said opposite external side and is held in place around said rim of said container in an open manner and in operative cooperation with the internal facing surface and the rim portion to substantially prevent the development of a gap between the liner and the internal facing and rim portion of the container.

2. The device in claim 1 wherein said cap member is attached to said protruding member.

3. The device in claim 1 wherein said cap member is equipped with a decorative design.

4. The device in claim 1 wherein said snap-type fastener is of original manufacture to the container.

5. The device of claim 1 in combination with a commercially available container.

6. A device for securing a flexible plastic liner around the rim of a container wherein:

the container has generally upright side portions and the side portions terminating in a substantially continuous rim portion;

further including

a plurality of snap-type fasteners consisting of a cap member and protruding member extending outwardly from the side portions and capable of grasping and maintaining a portion of the mouth of said liner, said snap-type fasteners situated on opposite external sides of said container a sufficient distance below the rim of said container so as to work in cooperative association to increase the effective circumference of the mouth of said liner, whereby said mouth of said liner which is held in place around said rim of said container in an open manner and in operative cooperation with the internal facing surface and the rim portion to substantially present the development of a gap between said liner and the internal facing and rim portion of the container.

7. A device for securing a flexible plastic liner around the rim of a container, comprising;

a snap-type fastener comprising of a cap member and protruding member extending outwardly from a side portion of the container and capable of grasping and maintaining a portion of said flexible plastic liner between the cap member and the protruding member; and

means for combining the snap-type fastener with the container a sufficient distance below the rim of the container.

8. The device of claim 7 wherein the snap-type fastener includes a base member and the means for combining includes at least one rivet projection.

9. The device of claim 7 wherein the means for combining includes at least one threaded portion, a nut member received by each threaded portion maintaining the snap-type fastener in combination with the container.

10. The device of claim 8 wherein the rivet projection includes a compressible end portion.

11. The device of claim 7 wherein the means for combining includes a plurality of rivet projections.

12. The device of claim 7 wherein the means for combining includes a plurality of rivet projections.

13. The device of claim 9 wherein said at least one threaded portion comprises two threaded portions and said respective nut members received by the threaded portions maintain the snap-type fastener in combination with the container.

14. The device of claim 12 wherein two rivet projections including compressible end portions maintain the snap-type fastener in combination with the container.

15. The device of claim 7 wherein the means to combine includes one threaded portion and a nut member received by the threaded portion and a retaining hook maintain the snap-type fastener in combination with the container.

16. The device of claim 12 wherein one rivet projection including a compressible end portion and a retaining hook maintain the snap-type fastener in combination with the container.

17. The device of claim 7 wherein the snap-device fastener has a friction surface on an inside portion of the cap member normally in opposition with the protruding member when in use.

18. The device of claim 7 wherein the snap-type fastener has a friction surface on a portion of the protruding member normally in opposition with the cap member when in use.

19. The device of claim 7 wherein the snap-type fastener protruding member is an extension of the container.

20. The device of claim 7 wherein the snap-type fastener cap member includes a retaining means for retaining the cap member relative to the protruding member.

21. The device of claim 7 wherein the snap-type fastener includes a ring at the end of an extension and the ring fits generally around the protruding member, whereby fastening the cap member on the protruding member maintains the ring relative to the protruding member.

22. The device of claim 7 wherein the snap-type fastener includes a retaining means integral with the cap member and the protruding member and intermediate the cap member and the protruding member.

23. The device of claim 7 wherein the means for combining includes a base member and the base member carries an adhesive backing.

24. The device of claim 7 wherein the means for combining includes the snap-type fastener having a base member which is secured to the container by an adhesive applied to the container.
