Abstract

An adhesive article adapted for removable adhesive bonding on a support surface, such as a wall, includes a base member and a stretch release adhesive tape strip. The adhesive tape strip is a sequential release-type adhesive strip having a non-adhesive end portion which allows the base member to release from the adhesive strip during the removal process while the adhesive strip remains adhered to the support surface, therefore reducing the incidence of unwanted catapulting. To prevent relative movement between the base member and the adhesive strip during the removal process and therefore increase the likelihood of successful controlled sequential release of the base member, the base member includes a stabilizer arranged to abut the adhesive strip if the base member shifts as the adhesive strip is stretched during removal. The stabilizer can be a generally rigid projection or a compressible stop member which extends outwardly from the end of the base member adjacent the end of the adhesive strip.

Claims

1. A stretch releasing adhesive article adapted to be removably affixed to a support surface, comprising

(a) a stretch releasing adhesive strip having opposed adhesive top and bottom major surfaces and opposed first and second ends, said adhesive strip including a non-adhesive tab portion at said second end;

and

(b) a base member affixed to one of said top and bottom major surfaces, said base member having opposed top and bottom major surfaces and opposed first and second ends, said base member including a stabilizer arranged adjacent said adhesive strip first end thereby to prevent relative movement between said adhesive strip and said base member during the stretch removal of the adhesive strip from the support surface and said base member.

2. An adhesive article as defined in claim 1, wherein said stabilizer extends from said base member bottom surface first end adjacent said adhesive strip first end.

3. An adhesive article as defined in claim 2, wherein said stabilizer comprises at least one projection arranged transversely along said base member bottom surface first end.

4. An adhesive article as defined in claim 3, wherein said stabilizer is a rigid projection.

5. An adhesive article as defined in claim 3, wherein said stabilizer is compressible.

6. An adhesive article as defined in claim 5, wherein said stabilizer includes a repositionable adhesive arranged for engagement with the support surface.

7. An adhesive article as defined in claim 6, wherein said stabilizer is formed of a polymeric foam material.

8. An adhesive article as defined in claim 5, wherein said stabilizer comprises a folded flexible stop member having a tapered V-shaped configuration having a wide open end arranged to abut said adhesive strip first end.

9. An adhesive article as defined in claim 1, wherein said adhesive strip top surface first end includes a generally non-adhesive release area arranged remote from said non-adhesive tab portion and adjacent said base member stabilizer.
