  "title": "Stretch releasing adhesive article with shape retaining member",
  "abstract": "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.",
  "claims": [
    "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.",
    "2. A stretch releasable adhesive tape article as defined in claim 1, wherein said shape retaining member is stiff and bendable.",
    "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."
