CONDOM HAVING A FOAM TIP
A condom that includes a tubular shaft comprising a polymeric composition and having an open end and a closed end, a hollow interior chamber disposed between the open end and the closed end, and an open-cell foam tip portion disposed on at least one of an internal portion of the closed end and/or an exterior surface of the closed end, wherein the tubular shaft and the open end are adapted for receiving a penis of a wearer.
1 . A condom, comprising:
a tubular shaft comprising a polymeric composition and having an open end and a closed end having a tip;
a hollow interior chamber disposed between the open end and the closed end; and
an open-cell foam tip portion formed on at least one of an inner surface or an outer surface of the tip,
wherein the tubular shaft and the open end are adapted for receiving a penis of a wearer.
2 . The condom of claim 1 , wherein the open-cell foam tip portion is adapted to deliver at least one active ingredient to the penis of the wearer.
3 . The condom of claim 1 , wherein the open-cell foam tip portion is adapted to localize the at least one active ingredient.
4 . The condom of claim 1 , wherein the open-cell foam tip portion is integrally formed with the tubular shaft.
5 . The condom of claim 2 , wherein the at least one active ingredient is an anti-viral, an anti-microbial, an anti-fungal, a vasodilator, a benzocaine, a warming liquid or gel, a spermicide, or a lubricant.
6 . The condom of claim 1 , wherein the open-cell foam tip portion is approximately 20-60 mm in length.
7 . The condom of claim 1 , wherein the open-cell foam tip portion comprises a cross-sectional thickness of approximately 20-100 microns.
8 . The condom of claim 1 , wherein the open cell polymeric foam comprises at least one of natural polyisoprenes, synthetic polyisoprenes, carboxylated butadiene-nitriles, polyurethanes or polyurethane-polyurea copolymers, or combinations thereof.
9 . The condom of claim 1 , wherein the open cell polymeric foam has a cell size of approximately 5-50 microns.
10 . The condom of claim 1 , wherein the tip portion is an open cell foam tip formed on an interior surface of the hollow interior chamber.
11 . A method for forming a condom, comprising:
dipping a condom into a foamed latex composition, thereby coating a layer of foamed latex composition onto the condom; and
curing the layer of foamed latex composition to form a condom, wherein the layer of foamed latex composition is an open cell polymeric foam.
12 . The method for forming a condom of claim 11 , wherein the open cell polymeric foam comprises at least one of natural polyisoprenes, synthetic polyisoprenes, carboxylated butadiene-nitriles, polyurethanes or polyurethane-polyurea copolymers, or combinations thereof.
13 . The method for forming a condom of claim 11 , wherein the open cell foam has a cell size of approximately 5-50 microns.
14 . A method for forming a condom, comprising:
disposing a polymeric composition onto a former, thereby forming a first polymeric layer;
removing the former from the polymeric composition;
disposing a foamed polymeric composition onto the first polymeric layer, thereby forming a foamed second polymeric layer; and
curing the first polymeric layer and the foamed second polymeric layer to form a condom.
15 . The method for forming a condom of claim 14 , wherein the foamed second polymeric foam comprises at least one of natural polyisoprenes, synthetic polyisoprenes, carboxylated butadiene-nitriles, polyurethanes or polyurethane-polyurea copolymers, or combinations thereof.
16 . The method for forming a condom of claim 14 , further including disposing at least one active ingredient into the foamed second polymeric layer.
17 . The method of claim 16 , wherein the at least one active ingredient is an anti-viral, an anti-microbial, an anti-fungal, a vasodilator a benzocaine, a warming liquid or gel, a spermicide, or a lubricant.
18 . The method for forming a condom of claim 14 , wherein the first polymeric layer comprises at least one of natural polyisoprenes, synthetic polyisoprenes, carboxylated butadiene-nitriles, polyurethanes or polyurethane-polyurea copolymers, or combinations thereof.
19 . The method for forming a condom of claim 14 , further comprising disposing a coagulant onto the first polymeric layer, wherein the coagulant is disposed before the disposing the foamed polymeric composition onto the first polymeric layer.
20 . The method for forming a condom of claim 14 , further comprising a step for inverting the condom.
