Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
59 words
A heat-shrinkable article comprising a heat-shrinkable sheet having two edges adapted to form a closure, said edges being heat-stable, at least one of said edges having thereon a silicone-based pressure sensitive adhesive adapted, after compression against the other of said edges to form a closure, to maintain said closure at a temperature sufficiently high to shrink said heat-shrinkable sheet.
Claim 2
Dependent Claim
59 words
A heat-shrinkable article comprising a heat-shrinkable sheet having two edges adapted to form a closure, said edges being heat-stable, at least one of said edges having thereon a silicone-based pressure sensitive adhesive adapted, after compression against the other of said edges to form a closure, to maintain said closure at a temperature sufficiently high to shrink said heat-shrinkable sheet.
Claim 3
Dependent Claim
37 words
A heat-shrinkable article in accordance with claim 1, wherein said edges have mating portions so formed that, after formation of said closure and shrinking of said heat-shrinkable sheet, said closure is not significantly thicker than said sheet.
Claim 4
Dependent Claim
18 words
A heat-shrinkable article in accordance with claim 1, wherein said edges contain a built-in aligning and holding device.
Claim 5
Dependent Claim
18 words
A heat-shrinkable article in accordance with claim 1, wherein silicone is used to produce greater high temperature adhesion.
Claim 6
Dependent Claim
28 words
A heat-shrinkable article in accordance with claim 1, wherein said heat-shrinkable sheet has been irradiated to a dosage substantially greater than that required to impart heat-shrinkable properties thereto.
Claim 7
Dependent Claim
67 words
A process for making a heat-shrinkable article comprising the following steps: forming a heat-shrinkable sheet having two edges adapted to form a closure, said edges being heat-stable, and pressing against at least one of said edges a silicone-based pressure-sensitive adhesive adapted, after compression against the other of said edges to form a closure, to maintain said closure at a temperature sufficiently high to shrink said heat-shrinkable sheet.
Claim 8
Dependent Claim
67 words
A process for making a heat-shrinkable article comprising the following steps: forming a heat-shrinkable sheet having two edges adapted to form a closure, said edges being heat-stable, and pressing against at least one of said edges a silicone-based pressure-sensitive adhesive adapted, after compression against the other of said edges to form a closure, to maintain said closure at a temperature sufficiently high to shrink said heat-shrinkable sheet.
Claim 9
Dependent Claim
102 words
A process for ensleeving an article comprising the following steps: wrapping about an article to be ensleeved a heat-shrinkable article comprising a heat-shrinkable sheet having two edges adapted to form a closure, said edges being heat-stable, at least one of said edges having thereon a silicone-based pressure sensitive adhesive adapted, after compression against the other of said edges to form a closure, to maintain said closure at a temperature sufficiently high to shrink said heat-shrinkable sheet, compressing said two edges together so as to form a closure, and heating said heat-shrinkable article to a temperature sufficiently high to shrink said heat-shrinkable sheet.
Claim 10
Dependent Claim
102 words
A process for ensleeving an article comprising the following steps: wrapping about an article to be ensleeved a heat-shrinkable article comprising a heat-shrinkable sheet having two edges adapted to form a closure, said edges being heat-stable, at least one of said edges having thereon a silicone-based pressure sensitive adhesive adapted, after compression against the other of said edges to form a closure, to maintain said closure at a temperature sufficiently high to shrink said heat-shrinkable sheet, compressing said two edges together so as to form a closure, and heating said heat-shrinkable article to a temperature sufficiently high to shrink said heat-shrinkable sheet.
