Abstract
Abstract A cold compress includes a generally flat self-contained cooling member adapted to undergo an endothermic reaction upon physical manipulation. A generally thermal wetting member which includes a liquid is provided in thermal contact with the self-contained cooling member. An envelopment is provided for sealingly enclosing at least the wetting member including the liquid. The self-contained cooling member includes a substances which undergoes an endothermic reaction upon physical manipulation, whereby heat is absorbed from the wetting member into the self-contained cooling member.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
160 words
A cold compress for providing a moisturizing cold compress treatment to skin comprising: a self-contained cooling member adapted to undergo an endothermic reaction upon stimulation; a wetting member including a liquid, said wetting member being thermally coupled to said self-contained cooling member, said wetting member including a base member formed of fibrous material, said liquid retained in said base member, said wetting member having a thickness smaller than that of said cooling member; an adhesive between said self-contained cooling member and said wetting member to bond said cooling member and said wetting member; and envelope means for sealingly enclosing therein said self-contained cooling member and said wetting member which are bonded with each other, said envelopment means including a bag-shaped member formed of a plastic film to provide an air impermeable seal; wherein said wetting member is adapted for direct contact with the skin upon opening of said envelop means to effect the moisturizing cold compress treatment of the skin.
Claim 2
Dependent Claim
160 words
A cold compress for providing a moisturizing cold compress treatment to skin comprising: a self-contained cooling member adapted to undergo an endothermic reaction upon stimulation; a wetting member including a liquid, said wetting member being thermally coupled to said self-contained cooling member, said wetting member including a base member formed of fibrous material, said liquid retained in said base member, said wetting member having a thickness smaller than that of said cooling member; an adhesive between said self-contained cooling member and said wetting member to bond said cooling member and said wetting member; and envelope means for sealingly enclosing therein said self-contained cooling member and said wetting member which are bonded with each other, said envelopment means including a bag-shaped member formed of a plastic film to provide an air impermeable seal; wherein said wetting member is adapted for direct contact with the skin upon opening of said envelop means to effect the moisturizing cold compress treatment of the skin.
Claim 3
Dependent Claim
44 words
A cold compress as recited in claim 1, wherein said self-contained cooling member comprises a substance which undergoes an endothermic reaction upon stimulation by physical manipulation of said self-contained cooling member, whereby heat is absorbed from said wetting member into said self-contained cooling member.
Claim 4
Dependent Claim
28 words
A cold compress as recited in claim 1, said liquid of said wetting member being a medicative liquid, and said wetting member being formed of a non-woven fabric.
Claim 5
Dependent Claim
40 words
A cold compress as recited in claim 1, said self-contained cooling member and said wetting member each being generally flat, wherein a first flat surface of said self-contained cooling member is disposed along a flat surface of said wetting member.
Claim 6
Dependent Claim
40 words
A cold compress as recited in claim 2, said self-contained cooling member and said wetting member each being generally flat, wherein a first flat surface of said self-contained cooling member is disposed along a flat surface of said wetting member.
Claim 7
Dependent Claim
47 words
A cold compress as recited in claim 4, further comprising a second wetting member including a liquid and being generally flat, wherein a second flat surface, opposing the first flat surface, of said self-contained cooling member is disposed along a flat surface of said second wetting member.
