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: 9
Claim 1
Independent Claim
102 words
A removable reuseable thermal insulator for containers, said insulator comprising in combination: (a) a sheet of foam for circumscribingly engaging the container and thermally insulating the portions of the container proximate said sheet from heat transfer intermediate the container and the ambient environment, said sheet including opposed ends; and (b) adhesive means for non-permanently securing said opposed ends in positional relationship to one another upon engagement of said insulator about the container and thereby maintaining said insulator mounted upon the container; whereby, said insulator is removably engageable about and maintainable upon the container to insulate thermally the container from the ambient environment.
Claim 2
Dependent Claim
102 words
A removable reuseable thermal insulator for containers, said insulator comprising in combination: (a) a sheet of foam for circumscribingly engaging the container and thermally insulating the portions of the container proximate said sheet from heat transfer intermediate the container and the ambient environment, said sheet including opposed ends; and (b) adhesive means for non-permanently securing said opposed ends in positional relationship to one another upon engagement of said insulator about the container and thereby maintaining said insulator mounted upon the container; whereby, said insulator is removably engageable about and maintainable upon the container to insulate thermally the container from the ambient environment.
Claim 3
Dependent Claim
37 words
The insulator as set forth in claim 1 wherein said adhesive means comprises material having an adhesive disposed on at least one surface thereof for adhesively engaging a surface of at least one of said opposed ends.
Claim 4
Dependent Claim
25 words
The insulator as set forth in claim 2 wherein a surface of said insulator includes printing visible upon mounting of said insulator about the container.
Claim 5
Dependent Claim

Claim 6
Dependent Claim
32 words
The insulator as set forth in claim 2 wherein said adhesive means includes an adhesive disposed on said material for adhesively engaging surfaces of said sheet proximate each of said opposed ends.
Claim 7
Dependent Claim
14 words
The insulator as set forth in claim 5 wherein said sheet comprises polyethylene foam.
Claim 8
Dependent Claim
15 words
The insulator as set forth in claim 6 wherein said sheet comprises cross-linked polyethylene foam.
Claim 9
Dependent Claim
25 words
The insulator as set forth in claim 7 wherein a surface of said insulator includes printing visible upon mounting of said insulator upon the container.
