Stretch releasing adhesive article with shape retaining member
A stretch releasable adhesive tape article includes an extensible adhesive strip having a non-adhesive pull tab and a shape retaining member arranged within or adjacent to the adhesive strip. The shape retaining member is repeatably manually movable between a first position allowing a user to manually grasp the non-adhesive pull tab to stretch release the adhesive strip from a substrate, and a displaced position for maintaining the non-adhesive pull tab at a position offset from the first position.
1. A stretch releasable adhesive tape article, comprising:
(a) an extensible adhesive strip having an adhesive first end portion and a non-adhesive second end portion defining a pull tab; and
(b) a shape retaining member connected with said adhesive strip and arranged adjacent to said adhesive strip first and second end portions, said shape retaining member being repeatably manually movable between a first position allowing a user to manually grasp said non-adhesive pull tab to stretch release said adhesive strip from a substrate, and a displaced position for maintaining said non-adhesive pull tab at a position offset from said first position.

3. A stretch releasable adhesive tape article as defined in claim 2 , wherein said adhesive first end portion has opposed first and second major surfaces at least one of which is adhesive, said non-adhesive pull tab comprises a second end portion of said adhesive strip, and said shape retaining member is affixed to said first end portion adhesive surface and extends in overlapping relation with said non-adhesive pull tab.
4. A stretch releasable adhesive tape article as defined in claim 3 , wherein said shape retaining member is adhesively bonded to said first end portion adhesive surface.
5. A stretch releasable adhesive tape article as defined in claim 1 , wherein said shape retaining member is formed of metal.
6. A stretch releasable adhesive tape article as defined in claim 5 , wherein said metal is selected from the group consisting of steel, brass, aluminum, copper, and lead.
7. A stretch releasable adhesive tape article as defined in claim 5 , wherein said metal is annealed.
8. A stretch releasable adhesive tape article as defined in claim 5 , wherein said shape retaining member is an elongate metal bar having a thickness of less than about 0.05 inches.
9. A siretch releasable adhesive tape article as defined in claim 5 , wherein said shape retaining member is an elongate metal bar having a diameter of less than about 0.1 inches.
10. A stretch releasable adhesive tape article as defined in claim 1 , wherein said shape retaining member has a serpentine shape.
11. A stretch releasable adhesive tape article as defined in claim 1 , wherein said shape retaining member comprises a pair of generally parallel rails arranged adjacent to opposite side edges of said adhesive strip, whereby a user can grasp said non-adhesive pull tab between said rails and stretch release said adhesive strip from a substrate and from said rails.
12. A stretch releasable adhesive tape article as defined in claim 1 , wherein said shape retaining member has a lattice-like structure and is attached to said adhesive first end portion.
13. A stretch releasable adhesive tape article as defined in claim 1 , wherein said shape retaining member comprises a hinge movable between first and second fixed positions, said shape retaining member having a first end attached to said first end portion and a second end arranged adjacent to said non-adhesive pull tab portion.
14. A stretch releasable adhesive tape article as defined in claim 1 , wherein said shape retaining member is arranged within said adhesive strip.
15. A stretch releasable adhesive tape article as defined in claim 14 , wherein an intermediate portion of said shape retaining member is arranged within said adhesive strip non-adhesive pull tab and end portions of said shape retaining member are arranged adjacent to and extend along side edges of said adhesive strip.
16. A stretch releasable adhesive tape article as defined in claim 1 , wherein said adhesive strip has a multi-layer construction.
17. The stretch releasable adhesive tape article of claim 1 , wherein said article is configured such that said non-adhesive pull tab is maintained in a plane more offset from a plane of said first end portion in said displaced position than in said first position.
18. The stretch releasable adhesive tape article of claim 1 , wherein said article is configured such that said shape retaining member selectively maintains said non-adhesive pull tab at a plurality of longitudinal extension positions relative to said first end portion.
19. The stretch releasable adhesive tape article of claim 1 , wherein said first position and said displaced position relate to a position of said non-adhesive pull tab relative to said first end portion.
20. The stretch releasable adhesive tape article of claim 1 , wherein said shape retaining member contacts said adhesive strip.
21. A stretch releasable adhesive tape article, comprising:
(a) an extensible adhesive strip having a non-adhesive pull tab; and
(b) shape retaining means connected with said adhesive strip and arranged adjacent to said adhesive strip non-adhesive pull tab, said shape retaining means being repeatably manually movable between a first position allowing a user to manually grasp said non-adhesive pull tab to stretch release said adhesive strip from a substrate, and a displaced position for maintaining said non-adhesive pull tab at a position offset from said first position.
