Abstract

A condom is provided for enhancing feeling and stimulation on the part of the male by allowing the condom to move, e.g., by a sliding action on the surface of the penis during intercourse. Typically the distal end of the condom is frictionally related to the vagina by weakly bonding the condom to the vagina as by means of a gum-like adhesive agent or by means of a multiplicity of minute fibers bonded on the outside surface of the condom or both. The condom near its open end is held tightly against the base of the penis and, if desired, weakly bonded thereto by means of a removable adhesive to form a tight seal.

Claims

1. A male stimulating condom comprising, a condom body having an inside and an outside, a closed end portion of the condom being adapted to slide on the penis during use and being adapted to contain a lubricant therein to facilitate sliding movement thereon to increase penile stimulation and provide a greater sense of feeling due to a rubbing action between the condom and the penis, and an adhesion-producing agency on the outside of the condom to reduce slippage between the vagina and the condom and said adhesion-producing agency is a member selected from the group consisting of polycarbophil, hydroxypropyl methylcellulose, polyacrylamide, polyacrylic acid, vinylacetate dioctyl maleate copolymer, acetylcysteine, glutaraldehyde, and a compound adapted to provide a source of calcium ions.

2. The condom of Claim 1 wherein said calcium-containing compound comprises a member selected from the group consisting of calcium chloride, calcium gluconate and dibasic calcium phosphate.

3. A male stimulating condom comprising, a condom body having an inside and an outside, a closed end portion of the condom being adapted to slide on the penis during use and being adapted to contain a lubricant therein to facilitate sliding movement thereon to increase penile stimulation and provide a greater sense of feeling due to a rubbing action between the condom and the penis, a matrix applied to the outside surface of the condom, said matrix comprising a member selected from the group consisting of a polyacrylic ester, acrylic ester-acrylic acid copolymer, carboxylated styrene/butadiene rubber latex, polyisopreee rubber and a hydrophilic adhesion-producing agency on the outside of the condom to reduce slippage between the vagina and the condom, said matrix being adapted to bond the adhesion-producing agency to the outside surface of the condom.

4. A male stimulating condom comprising, a condom body having an inside and an outside, a closed end portion of the condom being adapted to slide on the penis during use and being adapted to contain a lubricant therein to facilitate sliding movement thereon to increase penile stimulation and provide a greater sense of feeling due to a rubbing action between the condom and the penis, an adhesion-producing natural or synthetic hydrophilic polymer as a coating on the outside of the condom to reduce slippage between the vagina and the condom, said polymer being at least partially hydrated with a polar fluid selected from the group consisting of water and a hydric alcohol to provide a smooth, homogenous and flexible friction-producing coating on the outer surface of the condom.

5. The condom of Claim 4 wherein a matrix composed of an elastic, rubbery material is applied to the condom between an outer wall thereof and the adhesion-producing polymer as a tie coat to bond the adhesion-producing polymer in place.

6. The condom of Claim 4 wherein the polar fluid comprises a member selected from the group consisting of glycerin, ethyleneglycol, propyleneglycol, polyoxyethylene and polyvinyl alcohol.

7. The condom according to Claim 4 wherein a slippery fluid or semifluid lubricant is applied over the hydrophilic friction imparting coating.

8. The condom of Claim 7 wherein the lubricant comprises a silicone lubricant.

9. A contraceptive device comprising, an elongated hollow tubular contraceptive body having an inside and outside, said tubular body being closed at one end and being formed from a flexible and supple material adapted to conform to the body contours, said contraceptive body being constructed and arranged and of sufficient size to slide relative to the penis during intercourse throughout at least a substantial portion of the length thereof to make possible a rubbing action between the contraceptive device and the penis, and means to frictionally relate the contraceptive device to the vagina comprising at least one member selected from the group consisting of a multiplicity of fibers on the outer surface of the contraceptive device, a friction imparting adhesive agent, a composition to thicken the vaginal fluid and an astringent, said means enhancing the frictional relationship between the contraceptive device and the vagina causing the contraceptive device to tend to cling to the surface of the vagina and promoting sliding movement between the contraceptive device and the penis.

10. The contraceptive device of claim 9 wherein the device has means on the inside providing a textured inner surface to promote stimulation of the penis.

11. The contraceptive device of claim 9 wherein said adhesive comprises a natural or synthetic water soluble or water swellable polymeric hydrocolloid on the outer surface of the device.

12. The contraceptive device of claim 11 wherein the hydrocolloid is bonded to the contraceptive device by means of a rubbery matrix adhered to the outer surface of the device.

13. The contraceptive device of claim 9 wherein the outside surface of the contraceptive device is flocked with fibers and the fibers are bonded thereto.

14. The contraceptive device of claim 12 wherein the hydrocolloid is in particulate form and is bonded to the contraceptive device with a hydrophobic rubbery matrix applied to an outer surface of said contraceptive device.

15. The contraceptive device of claim 9 wherein a lubricant is applied to said contraceptive device over said frictional means to facilitate insertion of the contraceptive device into the vagina.
