Abstract
Abstract An elongated sheet of crosslinked polyethylene foam, which type of foam can be imprinted with conventional printing inks, is wrapped about the cylindrical surface of a cylindrical container for thermal insulation of the container contents. A strip of adhesive is deposited upon one side at one end of the sheet to receive and removably retain an overlapped portion of the other end of the sheet to secure the sheet about the container.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
107 words
A removable reusable thermal insulator for containers, said insulator cpmprising in combination: (a) a sheet of crosslinked polyethylene foam for contactingly circumscribingly engaging the container, said sheet having opposed ends, said sheet being sized in width and length to circumscribe the container with at least partial overlap of said opposed ends; and (b) adhesive means disposed upon a surface of one of said opposed ends for non-permanently adhering said one opposed end to the other of said opposed ends upon circumscribing mounting of said insulator about the container; whereby, said insulator is removably mountable in contacting relationship about the container to insulate thermally the contacted container surface.
Claim 2
Dependent Claim
107 words
A removable reusable thermal insulator for containers, said insulator cpmprising in combination: (a) a sheet of crosslinked polyethylene foam for contactingly circumscribingly engaging the container, said sheet having opposed ends, said sheet being sized in width and length to circumscribe the container with at least partial overlap of said opposed ends; and (b) adhesive means disposed upon a surface of one of said opposed ends for non-permanently adhering said one opposed end to the other of said opposed ends upon circumscribing mounting of said insulator about the container; whereby, said insulator is removably mountable in contacting relationship about the container to insulate thermally the contacted container surface.
Claim 3
Dependent Claim
60 words
The insulator as set forth in claim 1 wherein said adhesive means commprises a length of tape having a first side and a second side, first adhesive means disposed upon said first side for adhering said tape to said one opposed end and second adhesive means disposed upon said second side for adhering said tape to said other opposed end.
Claim 4
Dependent Claim
57 words
The insulator as set forth in claim 2 wherein said first adhesive means is of greater adhering strength than said second adhesive means for encouraging disengagement between said tape and said other opposed end prior to disengagement between said tape and said one opposed end upon application of a force to dismount said insulator from the container.
Claim 5
Dependent Claim
28 words

The insulator as set forth in claim 1 including a partial slit disposed in the other surface of said one opposed end and proximate said adhesive means.
Claim 10
Dependent Claim
20 words
The insulator as set forth in claim 3 wherein the thickness of said sheet is not more than 1/8 inch.
Claim 11
Dependent Claim
26 words
The insulator as set forth in claim 9 wherein the length of said sheet is ten inches and the width of said sheet is four inches.
Claim 12
Dependent Claim
28 words
The insulator as set forth in claim 1 including means for reducing the adhesion between said adhesive means and the adhering surface of one of said opposed ends.
Claim 13
Dependent Claim
22 words
The insulator as set forth in claim 11 wherein said reducing means comprises deposition of a release agent upon an adhering surface.
Claim 14
Dependent Claim
23 words
