Abstract
Abstract A condom of elastomeric film material composed of a vulcanized blend of thermoplastic elastomer with a low modulus polyolefin such as a low-density polyethylene wherein the condom includes a tubular length having a closed first end and an open second end and may also include an integral pubic shield about the open end with the tubular length being sized to receive the penis of a user and the pubic shield being adapted to overlay the pubic area of a user.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
53 words
A condom of rubbery film material comprising a sleeve having an open proximal end and a closed end and being sized to receive an erect penis, said material comprising a blend of polyolefin material and thermoplastic elastomer material; said film material comprising an olefinic vulcanized blend of thermoplastic elastomer and low modulus polyolefin.
Claim 2
Dependent Claim
53 words
A condom of rubbery film material comprising a sleeve having an open proximal end and a closed end and being sized to receive an erect penis, said material comprising a blend of polyolefin material and thermoplastic elastomer material; said film material comprising an olefinic vulcanized blend of thermoplastic elastomer and low modulus polyolefin.
Claim 3
Dependent Claim
19 words
A condom of rubbery film material as set forth in claim 1 wherein the polyolefin comprises ultra low-density polyethylene.
Claim 4
Dependent Claim
14 words

Claim 8
Dependent Claim
58 words
A condom of rubbery material comprising a sleeve having an open proximal end and a closed end and being sized to receive an erect penis, said material comprising a blend of polyolefin material and thermoplastic elastomer material, said blend being characterized by a low modulus polyolefin comprising a co-polymer, polymerizable with other polymer molecules to form a chain.
Claim 9
Dependent Claim
58 words
A condom of rubbery material comprising a sleeve having an open proximal end and a closed end and being sized to receive an erect penis, said material comprising a blend of polyolefin material and thermoplastic elastomer material, said blend being characterized by a low modulus polyolefin comprising a co-polymer, polymerizable with other polymer molecules to form a chain.
Claim 10
Dependent Claim
55 words
