Abstract
Abstract A tape for sealing a dispensing opening in a container. The tape is permanently bonded at one end to the container adjacent a dispensing opening in the container, has an intermediate portion overlying the dispensing opening and sealed to the container wall around the dispensing opening, and a free end portion functioning as a grip. The tape differs from other similar tapes in that it is a laminate of two materials with one of the materials being a load bearing material and the other material being a rubbery material, whereby when the tape is removed from the dispensing opening in the usual manner, the load bearing material is stretched beyond its elastic limit and thus when the tape is released it will automatically coil up to an out-of-the-way position relative to the dispensing opening.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
67 words
A new article of manufacture comprising a self-coiling tape for sealing a dispensing opening, said tape being a laminate of first and second materials and having a normal planar static state, said first material being a load bearing material, and said second material being a rubbery material, said tape having inner and outer surfaces when in the position of intended use, and said first material being innermost.
Claim 2
Dependent Claim
67 words
A new article of manufacture comprising a self-coiling tape for sealing a dispensing opening, said tape being a laminate of first and second materials and having a normal planar static state, said first material being a load bearing material, and said second material being a rubbery material, said tape having inner and outer surfaces when in the position of intended use, and said first material being innermost.
Claim 3
Dependent Claim
21 words
The tape of claim 1 wherein said load bearing material has a low yield strength and a high ultimate tensile strength.
Claim 4
Dependent Claim
21 words
The tape of claim 1 wherein said first material is a plastics material having physical characteristics suitable for bonding to metal.
Claim 5
Dependent Claim
11 words
The tape of claim 3 wherein said plastics material is MYLAR.
Claim 6
Dependent Claim
12 words
The tape of claim 3 wherein said plastics material is unoriented polypropylene.
Claim 7
Dependent Claim
14 words
The tape of claim 1 wherein said second material is an acrylic acid copolymer.
Claim 8
Dependent Claim
45 words
The tape of claim 1 wherein said tape is secured to a container wall, said container wall has a dispensing opening therein, said tape overlies said dispensing opening and is sealed to said container wall surrounding said dispensing opening for temporarily closing said dispensing opening.
Claim 9
Dependent Claim
45 words
The tape of claim 7 wherein said tape includes first and second end portions, said first end portion being free of said container wall and defining a grip portion, and said second end portion being permanently secured to said container wall adjacent said dispensing opening.
Claim 10
Dependent Claim
41 words
The tape of claim 7 wherein the seal between said tape and said container wall is of a strength to effect permanent elongation of said first material during the normal removal of said tape from its position overlying said dispensing opening.
Claim 11
Dependent Claim
13 words
The tape of claim 1 wherein both of said materials are plastics materials.
Claim 12
Dependent Claim
91 words
A closure comprising a tape of the type peelably adhered to a wall of a container in an area circumjacent a pour opening in said container wall in covering relation to said pour opening and non-removably secured at one end to said wall outside said area, said tape being of a construction requiring said tape being pulled and at least in part permanently stretched attendant to being peeled off said container wall and including means operative upon release of said stretched tape for rolling said tape up toward its secured end.
Claim 13
Dependent Claim
91 words
A closure comprising a tape of the type peelably adhered to a wall of a container in an area circumjacent a pour opening in said container wall in covering relation to said pour opening and non-removably secured at one end to said wall outside said area, said tape being of a construction requiring said tape being pulled and at least in part permanently stretched attendant to being peeled off said container wall and including means operative upon release of said stretched tape for rolling said tape up toward its secured end.
Claim 14
Dependent Claim
23 words
A closure in accordance with claim 11 wherein said tape is a laminate of at least two different materials having different elongation characteristics.
Claim 15
Dependent Claim
34 words
A closure in accordance with claim 12 wherein said different materials include a first material in the form of a load bearing material and a second material in the form of a rubbery material.
Claim 16
Dependent Claim
15 words
A closure in accordance with claim 11 wherein said tape is formed of plastics material.
Claim 17
Dependent Claim
89 words
A closure comprising a tape of the type peelably adhered to a wall of a container in an area circumjacent a pour opening in said container wall in covering relation to said pour opening and non-removably secured at one end to said wall outside said area, the securement of said tape to said wall being of a nature requiring said tape being pulled attendant to being peeled off said container wall and including means operative upon release of said tape for rolling said tape up toward its secured end.
Claim 18
Dependent Claim
89 words
A closure comprising a tape of the type peelably adhered to a wall of a container in an area circumjacent a pour opening in said container wall in covering relation to said pour opening and non-removably secured at one end to said wall outside said area, the securement of said tape to said wall being of a nature requiring said tape being pulled attendant to being peeled off said container wall and including means operative upon release of said tape for rolling said tape up toward its secured end.
