Abstract

The present invention relates to a laminated structure comprising an adhesive coated strip which is mounted upon a release strip wherein the release strip includes a partible break and wherein the release strip farther includes a tab. Deflection of the release strip tab in a direction away from the adhesive coated strip generates a partial separation of the release strip tab from the general plane of the release strip at the partible break causing an edge of the adhesive coated strip to be exposed for grasping by the user. The present invention also relates to methods for removal of an adhesive coated strip from the release strip.

Claims

1. A laminated structure, comprising:

a substantially planar adhesive coated strip having a peripheral edge, a first side, and a second side;

a release strip having an outside edge, a partible break; and

wherein said first side of said adhesive coated strip is disposed upon said release strip and wherein said second side of said adhesive coated strip is exposed and wherein said partible break extends from a point on said outside edge beyond at least one said peripheral edge of said adhesive coated strip to an interior point on said release strip and wherein said partible break forms a deflectable tab, and wherein said release strip remains contiguous about said partible break subsequent to removal of said adhesive coated strip.

2. The laminated structure of claim 1, wherein deflection of said tab in a direction away from said adhesive coated strip generates a partial separation of said tab from general plane of said release strip at said partible break causing a portion of said peripheral edge of said adhesive coated strip to form a leading edge which is exposed fir grasping by a user to facilitate subsequent removal of said adhesive coated strip from said release strip.

3. The laminated structure of claim 1, wherein said partible break is a cut through said release strip.

4. The laminated structure of claim 1, wherein said partible break in said release strip extends beyond only one said peripheral edge of said adhesive coated strip.

5. The laminated structure of claim 1, wherein said partible break in said release strip extends beyond two said peripheral edges of said adhesive coated strip.

6. The laminated structure of claim 1 wherein said tab is of a size easily graspable by a user'"'"'s fingers.

7. The laminated structure of claim 6 wherein said tab is from about 2 mm to about 10 mm wide.

8. The laminated structure of claim 1 wherein said coated strip is comprised of a polyethylene film.

9. The laminated structure of claim 1 wherein said release strip is comprised of a release treated substance.

10. The laminated structure of claim 1 wherein said release strip is comprised of a fluoropolymer treated polyester.

11. The laminated structure of claim 1, wherein the laminated structure is provided in the form of a tooth whitening strip.

12. The laminated structure of claim 1, wherein said partible break is a line of weakness.

13. The laminated structure of claim 1, wherein said strip is formed from a polymer.

14. A laminated structure, consisting of:

a substantially planar adhesive coated strip having a peripheral edge;

a release strip having an outside edge, a partible break; and

wherein said adhesive coated strip is disposed upon said release strip and wherein said partible break extends from a point on said outside edge beyond at least one said peripheral edge of said adhesive coated strip to an interior point on said release strip and wherein said partible break forms a deflectable tab, and wherein said release strip remains contiguous about said partible break subsequent to removal of said adhesive coated strip.

15. A laminated structure, comprising:

a substantially planar adhesive coated strip having a peripheral edge;

a release strip having an outside edge, a partible break; and

wherein said adhesive coated strip is disposed upon said release strip and wherein said partible break extends from a point on said outside edge beyond said peripheral edge of said adhesive coated strip to an interior point on said release strip and wherein said partible break forms a deflectable tab having a portion which does not overlie the adhesive coated strip, and wherein said release strip remains contiguous about said partible break subsequent to removal of said adhesive coated strip.

16. The laminated structure of claim 15, wherein said partible break in said release strip extends beyond only one said peripheral edge of said adhesive coated strip.

17. The laminated structure of claim 15, wherein said interior point of said release strip is disposed outside of said adhesive coated strip.

18. The laminated structure of claim 15 wherein said coated strip is comprised of a polyethylene film.

19. The laminated structure of claim 15 wherein said release strip is comprised of a release treated substance.

20. A method of using a laminated structure, comprising:

(a) providing a laminated structure comprising;

(i) a substantially planar adhesive coated strip having a peripheral edge, a first side, and a second side;

(ii) a release strip having an outside edge, a partible break;

(iii) wherein said first side of said adhesive coated strip is disposed upon said release strip and wherein said second side of adhesive coated strip is exposed and wherein said partible break extends from a point on said outside edge beyond at least one said peripheral edge of said adhesive coated strip to an interior point on said release strip and wherein said partible break forms a deflectable tab, and wherein said release strip remains contiguous about said partible break subsequent to removal of said adhesive coated strip;

(b) deflecting said tab at said partible break; and

(c) grasping said adhesive coated strip to remove said adhesive coated strip from said release strip.

21. A laminated structure, comprising:

a substantially planar adhesive coated strip having a peripheral edge;

a release strip having an outside edge and a partible break which is a line of weakness; and

wherein said adhesive coated strip is disposed upon said release strip and wherein said partible break extends from a point on said outside edge beyond at least one said peripheral edge of said adhesive coated strip to an interior point on said release strip and wherein said partible break forms a deflectable tab, and wherein said release strip remains contiguous about said partible break subsequent to removal of said adhesive coated strip.

22. A laminated structure, comprising:

a substantially planar adhesive coated strip having a peripheral edge;

a release strip having an outside edge and a plurality of partible breaks; and

wherein said adhesive coated strip is disposed upon said release strip and wherein said partible breaks extend from a point on said outside edge beyond at least one said peripheral edge of said adhesive coated strip to an interior point on said release strip and wherein said partible breaks form a deflectable tab, and wherein said release strip remains contiguous about said partible breaks subsequent to removal of said adhesive coated strip.

23. The laminated structure of claim 22, further comprising another substantially planar adhesive coated strip.

24. A laminated structure, comprising:

a substantially planar adhesive coated strip having a peripheral edge; and

a release strip having an outside edge and a partible break which is a line of weakness;

wherein said adhesive strip is disposed upon said release strip such that said outside edge extends outwardly beyond said peripheral edge and said partible break extends inwardly from an edge of said release strip beyond at least one said peripheral edge of said adhesive coated strip to an interior point of said release strip, wherein said partible break is oriented such that when a rotational force is exerted on said outside edge, a portion of said adhesive coated strip will separate form said release strip to form a leading edge from a potion of said peripheral edge.

25. A laminated structure, comprising:

a substantially planar adhesive coated strip having a peripheral edge; and

a release strip having an outside edge and a plurality of partible breaks;

wherein said adhesive strip is disposed upon said release strip such that said outside edge extends outwardly beyond said peripheral edge and said partible breaks extend inwardly from an edge of said release strip beyond at least one said peripheral edge of said adhesive coated strip to an interior point of said release strip, wherein said partible breaks are oriented such that when a rotational force is exerted on said outside edge, a portion of said adhesive coated strip will separate form said release strip to form a leading edge from a potion of said peripheral edge.

26. The laminated structure of claim 25, further comprising another substantially planar adhesive coated strip.
