Benefits of technology

[0006] The present invention generally provides a condom that incorporates two distinct lubricating compositions. One such composition is a relatively high viscosity lubricant composition containing at least one desensitizing agent that is bottom shot into the interior of a nipple up condom to coat the interior surfaces thereof. A second, lower viscosity lubricant composition containing no desensitizing agent is top shot on the outside of the condom prior to, or at the same time as following the application of the bottom shot lubricant composition. The high viscosity lubricant composition with a desensitizing agent remains substantially in place during packing, shipping, storage, and use so that the full benefits of continuous contact with the desensitizing agent can be realized. In this manner, separation of the first lubricant composition containing the desensitizing agent from the exterior surfaces of the condom is maximized in order to minimize contact with the female partner and thereby avoid desensitization of the female genitalia.

Problems solved by technology

Such compositions are inconvenient to use, in that they require direct application to the male genitalia prior to intercourse.
In addition, these compositions typically expose the female partner to the composition and its desensitizing effects with such exposure being highly undesirable.

[0029] Preparation of a First Lubricant Composition

[0030] A first lubricant composition in accordance with the present invention having the formula shown in Table 1 was prepared as follows:

TABLE 1IngredientPercent w / wPropylene Glycol44.0%w / w.Polyethylene Glycol 40015.0%w / w.Lubrajel ®CG*35.0%w / wBenzocaine USP6.0%w / w100.0%

*Lubrajel ® is a registered trademark of Guardian Chemical Corporation, Hauppauge, New York and contains glyceryl polymethacrylate, propylene glycol and water.

[0031] A method for manufacturing the first lubricating composition shown in Table 1 is now be described, with reference to FIG. 11. A hemispherical jacketed kettle 31, is provided with heating and cooling equipment. The kettle is equipped with a variable speed counter current sweep scraper, and a variable speed air mixer with propellers, as known in the art, to provide proper agitation. Three pumps, represented by numerals 33 through 35, are used to charge the kettle 31 with the particular components of th...

Preparation of Second Lubricating Composition

[0034] A second lubricating composition containing no desensitizing agent and having the formula shown in Table 2 was prepared in the following manner:

TABLE 2IngredientPercent w / wProplylene Glycol68.20Polyethylene Glycol 4006.80Lubrajel ® CG*25.00100.00%

*Lubrajel ® CG is a registered trademark of Guardian Chemical Corporation and contains glyceryl polymethacrylate, propylene glycol and water.

[0035] For the preparation of a batch of about 1,400 kg (kilograms) of the second lubricating composition shown in Table 2, the pumps 33-35 are operated to discharge 954.8 kg of propylene glycol, 95.2 kg of polyethylene glycol, and 350 kg of Lubrajel® CG into a 400 gallon capacity kettle 31 from a storage container (not shown), respectively under stirring with a variable speed counter current sweep scraper, and variable speed airmixer with propellers. The contents of the kettle are heated to between 75° C. and 80° C. During heating the air mixer u...

Abstract

A condom having a first lubricating composition containing a male genitalia desensitizing agent on the inside surface thereof and a second lubricating composition on the outside surface thereof. The first lubricating composition has a higher viscosity than the second lubricating composition so that the first lubricating composition remains on the inside surface of the condom during packaging, shipping, storage, and use.

Description

RELATED APPLICATION [0001] This Application is related to co-pending Provisional Application Ser. No. 60 / 251,486 filed Dec. 5, 2000, for “Condom With Male Genital Desensitizer Lubricant”, and takes priority therefrom. The related Application is owned by the same Assignee herewith.FIELD OF THE INVENTION [0002] The field of the present invention relates generally to condoms, and more specifically to condoms having a lubricant system which includes a genital desensitizing agent and controls the application thereof to male genitalia. BACKGROUND OF THE INVENTION [0003] Much effort has been made to provide a composition containing a male desensitization agent suitable for preventing premature ejaculation. Many of these compositions provide a water-based lubricant with benzocaine as the active component at a concentration of from about 3% to 7.5%. Such compositions are inconvenient to use, in that they require direct application to the male genitalia prior to intercourse. In addition, thes...
