Abstract

Kits are described wherefrom a single tab film may be adhered to an elongated strip of stretch releasing adhesive tape to form a manually engageable pull tab at a selected location. Such a pull tab may be foldable so as to comprise an unobtrusive visual appearance, and may also be extendable so that the pull tab may be grasped to activate the stretch release.

Claims

1. A kit for providing multiple stretch releasing adhesive tape articles with protruding pull tabs, comprising:

a continuous roll of stretch releasing tape having first and second oppositely facing major surfaces, both surfaces comprising adhesive and at least one of the surfaces bearing a removable liner; and

,

a plurality of discrete tab film pieces;

wherein each of the tab film pieces comprises first and second oppositely facing major surfaces, at least one of which is an adherable surface.

2. The kit of claim 1 wherein the stretch releasing tape and the tab film pieces are packaged together.

3. The kit of claim 2 wherein the tab film pieces are provided in a dispenser which is packaged with the stretch releasing tape.

4. The kit of claim 3 wherein the roll of tape comprises a core and the dispenser is attached to the core.

5. The kit of claim 3 wherein the dispenser comprises a core upon which the roll of tape is wound.

6. The kit of claim 1 wherein the tab film pieces are packaged in a folded condition.

7. The kit of claim 6 wherein each tab film comprises at least one crease.

8. The kit of claim 1 wherein the tab film pieces are packaged in a Z-folded condition.

9. The kit of claim 8 wherein each tab film comprises at least two creases.

10. The kit of claim 8 wherein the creases are oppositely biased.

11. The kit of claim 1 wherein the tab film pieces are packaged in a dual Z-folded condition.

12. The kit of claim 11 wherein each tab film comprises at least four creases.

13. The kit of claim 12 wherein at least two of the creases are biased oppositely.

14. The kit of claim 1 wherein the discrete tab film pieces are different in color.

15. The kit of claim 1 wherein the tab film adherable surface comprises a treatment to improve adhesion to a pressure-sensitive adhesive.

16. A kit for providing multiple stretch releasing adhesive tape articles with protruding pull tabs, comprising:

a continuous roll of stretch releasing tape having first and second oppositely facing major surfaces, both surfaces comprising adhesive and at least one of the surfaces bearing a removable liner; and

,

a plurality of discrete tab film pieces;

wherein each of the tab film pieces comprises first and second oppositely facing major surfaces, at least one of which is an adherable surface; and

,

wherein each discrete tab film piece is attachable to both major surfaces of the stretch releasing adhesive tape so as to form a protruding pull tab, such that the stretch releasing property of the adhesive tape may be activated by grasping and pulling the protruding portion of the pull tab, without grasping any portion of the adhesive tape itself.
