Abstract
Abstract An ice pack which is constructed of a plurality of separate compartments which are connected together through a webbing assembly. Each of the compartments is movable in respect to each other permitting the ice pack to be located within confined various sizes of spaces. Within each compartment of the ice pack is located a quantity of freezable substance which is to be used as a refrigerant. Each compartment is enclosed by a wall assembly which retards the accumulation of moisture on the exterior surface of the wall assembly.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
178 words
A foldable ice pack comprising: a plurality of separate compartments, each said compartment to contain a refrigerant; a webbing assembly innerconnecting said compartments, said webbing assembly including a single thin webbing strip located between each connected pair of said compartments; each said compartment being enclosed by a wall assembly, said wall assembly comprising an inner layer of sheet material which is overlapped with an outer layer of sheet material, a slight air space is formed between said inner layer and said outer layer, said air space is to function as insulation retarding the accumulation of moisture on the exterior surface of said outer layer; an additional layer of sheet material located about said outer layer, a second air space formed between said additional layer and said outer layer, said second air space to function as insulation further retarding the accumulation of moisture on the exterior surface of said additional layer; and a drain opening formed within said additional layer, whereby any moisture accumulated within said second air space to be discharged to the ambient through said drain opening.
