Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
168 words
An inflatable condom comprising: (a) an anterior portion characterized by a generally tubular sheath open at one end and having a reinforcing rim adjacent said one end; (b) a secondary portion integrally formed in said anterior portion to close said anterior portion at the end opposite said one end and characterized by an expandible sheath having a relatively thin wall thickness, a sheath neck communicating between said anterior portion and said expandible sheath and an inner wall closing said sheath neck to seal said expandible sheath from said anterior portion, said sheath neck and said inner wall are thicker than said expandible sheath to facilitate minimum expansion of said sheath neck and said inner wall when said sheath is inflated; (c) duct means positioned inside said anterior portion and attached to said sheath neck and extending through said inner wall for inflating said expandible sheath; and pump means cooperating with said duct means for selectively inflating said expandible sheath from a point remotely located from said inflatable condom.
Claim 2
Dependent Claim
168 words
An inflatable condom comprising: (a) an anterior portion characterized by a generally tubular sheath open at one end and having a reinforcing rim adjacent said one end; (b) a secondary portion integrally formed in said anterior portion to close said anterior portion at the end opposite said one end and characterized by an expandible sheath having a relatively thin wall thickness, a sheath neck communicating between said anterior portion and said expandible sheath and an inner wall closing said sheath neck to seal said expandible sheath from said anterior portion, said sheath neck and said inner wall are thicker than said expandible sheath to facilitate minimum expansion of said sheath neck and said inner wall when said sheath is inflated; (c) duct means positioned inside said anterior portion and attached to said sheath neck and extending through said inner wall for inflating said expandible sheath; and pump means cooperating with said duct means for selectively inflating said expandible sheath from a point remotely located from said inflatable condom.
Claim 3
Dependent Claim
32 words
The inflatable condom of claim 1 further comprising valve means in cooperation with said duct means for selectively releasing air pressure in said expandible sheath and causing said expandible sheath to deflate.
