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;

and wherein the stretch releasing tape and the tab film pieces are packaged together but with the tab film pieces not being in contact with an adhesive surface of the stretch releasing tape.

2. The kit of claim 1 wherein the tab film pieces are provided in a dispenser which is packaged with the stretch releasing tape and which dispenses the tab film pieces but which does not contain or dispense the stretch releasing tape.

3. The kit of claim 2 wherein the roll of tape comprises a core and the dispenser is attached to the core.

4. The kit of claim 2 wherein the dispenser comprises a core upon which the roll of tape is wound.

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

6. The kit of claim 5 wherein each tab film comprises at least one crease.

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

8. The kit of claim 7 wherein each tab film comprises at least two creases.

9. The kit of claim 7 wherein the creases are oppositely biased.

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

11. The kit of claim 10 wherein each tab film comprises at least four creases.

12. The kit of claim 11 wherein at least two of the creases are biased oppositely.

13. The kit of claim 1 wherein at least some of the discrete tab film pieces are different in color from other of the discrete tab film pieces.

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

15. 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 surface, wherein the entirety of both oppositely facing major surfaces of each tab film piece consists of 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 that protrudes beyond a terminal edge of the stretch releasing adhesive tape such that at least a portion of the surface of the tab film piece is not in contact with an adhesive surface of the stretch releasing tape, such that the stretch releasing property of the adhesive tape may be activated by grasping and pulling the protruding pull tab, without grasping any portion of the adhesive tape itself.
