Abstract
Abstract A light-weight multi-layer insulating enclosure comprised of four different layers of materials to provide maximum insulation for containers ranging from relatively rigid to relatively flexible construction. The improved insulating qualities of the present invention are achieved through the use of an inner-most fabric liner layer, a second inner-most insulating layer which includes a polymeric foam, a third inner-most metalized polymer film reflective layer, and an outer-most fabric mesh layer. The enclosure is light-weight, collapsible and removable.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
133 words
A light-weight multi-layered insulating enclosure having an opening for receiving or removing a container, wherein said enclosure completely surrounds a container and is formed of four differing layers of materials laminated, stitched or adhesively joined (a) an inner-most knitted fabric liner layer, (b) a second inner most insulating layer next to said inner-most layer which includes polymer foam, (c) a third inner most polymer film reflective layer next to said inner most layer constructed of a polymer film coated with a reflective metallic material on the outer surface thereof, (d) an outermost knitted fabric mesh layer next to said third inner-most layer wherein said third inner-most polymer film reflective layer is constructed of a polymer film having an outer surface coated with a reflective metallic material visible through said outer-most fabric mesh layer.
Claim 2
Dependent Claim
133 words
A light-weight multi-layered insulating enclosure having an opening for receiving or removing a container, wherein said enclosure completely surrounds a container and is formed of four differing layers of materials laminated, stitched or adhesively joined (a) an inner-most knitted fabric liner layer, (b) a second inner most insulating layer next to said inner-most layer which includes polymer foam, (c) a third inner most polymer film reflective layer next to said inner most layer constructed of a polymer film coated with a reflective metallic material on the outer surface thereof, (d) an outermost knitted fabric mesh layer next to said third inner-most layer wherein said third inner-most polymer film reflective layer is constructed of a polymer film having an outer surface coated with a reflective metallic material visible through said outer-most fabric mesh layer.
