Abstract

Condoms having an elastomeric layer and coating containing an anhydrous warming lubricant and at least one or more ingredients dispersed therein, the coating being disposed on one or both surfaces are provided. The ingredients disposed on the elastomeric layer can be solid particles or encapsulated ingredients that are insoluble in the anhydrous warming lubricant and soluble in water. Methods of producing and using these condoms are also provided.

Claims

1. A condom, comprising:

an elastomeric layer having an outer surface and an inner surface; and

a coating disposed on the elastomeric layer, the coating comprising a substantially anhydrous liquid warming lubricant and a vasodilator disposed in the lubricant,

wherein the at least one vasodilator is provided as locally concentrated particles that are suspended in and not dissolved in the liquid warming lubricant and are soluble in water, resulting in a highly effective and concentrated form on a user'"'"'s skin upon contact with skin-generated moisture.

2. The condom of claim 1, wherein at least one of the locally concentrated particles is encapsulated.

3. The condom of claim 2, wherein the at least one locally concentrated particle is encapsulated in a water soluble capsule shell of gelatin, hydroxyalkyl cellulose, or combination thereof.

4. The condom of claim 1, wherein the warming lubricant comprises a glycerin, a polyhydric alcohol and non-ionic detergent in amounts effective to warm upon contact with skin-generated moisture.

5. The condom of claim 4, wherein the warming lubricant comprises substantially equal amounts of glycerin and a polyhydric alcohol.

6. The condom of claim 1, wherein a localized concentration of the at least one vasodilator is greater than the concentration of the vasodilator in the overall coating.

7. The condom of claim 1, wherein the warming lubricant comprises glycerin, propylene glycol, and a surfactant and the at least one vasodilator comprises at least one of niacin, ginger, L-arginine, or a nitric oxide precursor.

8. The condom of claim 1, wherein at least one of the locally concentrated particles is in solid phase.

9. The condom of claim 1, wherein the coating is disposed on the inner surface, the outer surface, or both.

10. The condom of claim 1, wherein the elastomeric layer is comprises of material selected from a group comprising natural rubber latex, synthetic polyisoprene, guayule, polyurethane, combinations thereof and copolymers thereof.

11. The condom of claim 1, wherein the coating further comprises a menthol component or a citric acid.

12. The condom of claim 1, wherein the condom is provided in a suitable package.

13. A condom, comprising:

an elastomeric layer having an outer surface and an inner surface; and

a coating disposed on one or both surfaces of the elastomeric layer, the coating comprising a substantially anhydrous liquid warming lubricant and an unencapsulated L-arginine component that is suspended in and not dissolved in the liquid warming lubricant and soluble in water and in a locally concentrated form,

wherein the liquid warming lubricant and the L-arginine component together produce an enhanced effect upon contact with body moisture as compared to the use of the L-arginine component without the presence of the liquid warming lubricant.

14. The condom of claim 13, wherein the coating further comprises a menthol component or a citric acid.

15. The condom of claim 13, wherein the warming lubricant comprises substantially equal amounts of glycerin and a polyhydric alcohol.

16. The condom of claim 13, wherein the L-arginine component is provided in a solid phase.

17. A method of manufacturing a condom comprising:

forming an elastomeric layer having an outer surface and an inner surface in the shape of a condom, wherein the elastomeric layer comprises a material selected from a group consisting of natural rubber latex, synthetic polyisoprene, guayule, polyurethane, combinations thereof or copolymers thereof; and

disposing a coating on the inner surface, the outer surface, or both of the elastomeric layer, the coating comprising a substantially anhydrous liquid warming lubricant and at least one vasodilator, disposed in the lubricant, the at least one vasodilator being provided in a locally concentrated form that is suspended in and not dissolved in the liquid warming lubricant and soluble in water;

wherein the warming lubricant and the at least one vasodilator together produce an enhanced effect upon contact of both with skin-generated moisture as compared with the use of the at least one vasodilator without the presence of the liquid warming lubricant.

18. The method of claim 17, comprising providing the at least one vasodilator as L-arginine in an unencapsulated solid phase.

19. The method of claim 17, comprising providing the at least one vasodilator in encapsulated form.

20. The method of claim 17, wherein the warming lubricant comprises a glycerin and a polyhydric alcohol.

21. A condom coating comprising:

substantially anhydrous liquid warming lubricant applicable to one or more surfaces of an elastomeric condom; and

locally concentrated, water-soluble particles comprising at least one vasodilator suspended in and not dissolved in the substantially anhydrous liquid warming lubricant.

22. The coating of claim 21, wherein the warming lubricant comprises glycerin, propylene glycol, and a surfactant.

23. The coating of claim 22, wherein the at least one vasodilator comprises at least one of niacin, ginger, L-arginine, or a nitric oxide precursor.

24. The coating of claim 21, wherein at least one of the particles is encapsulated.

25. The coating of claim 24, wherein the at least one encapsulated particle is/are encapsulated in a water soluble capsule shell of gelatin, hydroxyalkyl cellulose, or combination thereof.

26. The coating of claim 21, wherein the warming lubricant comprises a glycerin, a polyhydric alcohol and non-ionic detergent in amounts effective to warm upon contact with skin-generated moisture.

27. The coating of claim 26, wherein the warming lubricant comprises substantially equal amounts of glycerin and a polyhydric alcohol.

28. The coating of claim 21, wherein a localized concentration of the at least one vasodilator is greater than the concentration of the at least one vasodilator in the overall coating.

29. The coating of claim 21, wherein at least one of the particles is in solid phase.

30. The coating of claim 21, further comprising a menthol component or a citric acid.

31. A condom coating comprising:

substantially anhydrous liquid warming lubricant applicable to one or more surfaces of an elastomeric condom; and

an unencapsulated locally concentrated and water-soluble L-arginine component suspended in and not dissolved in the substantially anhydrous liquid warming lubricant,

wherein the liquid warming lubricant and the L-arginine component together produce an enhanced effect upon contact with body moisture as compared to the use of the L-arginine component without the presence of the liquid warming lubricant.

32. The coating of claim 31, further comprising a menthol component or a citric acid.

33. The coating of claim 31, wherein the warming lubricant comprises substantially equal amounts of glycerin and a polyhydric alcohol.

34. The coating of claim 31, wherein the L-arginine component is in a solid phase.

35. A method of preparing a condom, the method comprising:

providing a condom having an elastomeric layer with an outer surface and an inner surface;

preparing a coating comprising suspending substantially without dissolving, in substantially anhydrous liquid warming lubricant, locally concentrated, water-soluble particles comprising at least one vasodilator; and

disposing the coating on at least one of the outer surface and the inner surface of the condom,

wherein the warming lubricant and the at least one vasodilator together produce an enhanced effect upon contact of both with skin-generated moisture as compared with the use of the at least one vasodilator without the presence of the liquid warming lubricant.

36. The method of claim 35, wherein the elastomeric layer comprises a material selected from a group consisting of natural rubber latex, synthetic polyisoprene, guayule, polyurethane, combinations thereof, and copolymers thereof.

37. The method of claim 35 comprising providing the at least one vasodilator as L-arginine in an unencapsulated solid phase.

38. The method of claim 35 comprising providing the at least one vasodilator in encapsulated form.

39. The method of claim 35, wherein the warming lubricant comprises a glycerin and a polyhydric alcohol.
