Abstract: A positive mold form possessing a head portion including a reservoir portion, two bilaterally symmetric lobe portions, and a ridge line separating the head portion from a shaft portion has a perforated circumference connected to a bore in the shaft to which negative pressure is applied for holding a backing strip in position. Adhesive is applied to the exterior surface of the backing strip while negative pressure is maintained upon the same. Curing of the adhesive with a UV radiation source is suggested as if use of water soluble adhesive which is effective when immersed in isotonic fluid. An upper part of the positive mold form is coated with liquid elastomer and the resulting layer of elastomer cured with temperature reduction. Positive pressure applied to the perforated circumference effects release of the resulting elastomeric sheath, lifting the same off the positive mold form.

Abstract: Securement of a condom to the glans penis is facilitated by a pair of bilaterally symmetric areas provided for the lobes of the glans penis. It is recommended that the bilateral convex shape of the two lobes of the glans penis be adhered to by a close fitting shape molded into the condom which will resist accidental upward displacement. A viscous layer upon the interior surface enhances the suction characteristics in providing a greater cohesion coefficient between the condom and the skin contacted. A plurality of vacuum cups molded into the interior surface of the condom is also suggested. An expansible seminal fluid reservoir is provided, preferably located between the lobes of the glans are upon the tip of the condom. The resistance to accidental upward displacement provided by the suction areas adhered to the glans permit the condom to be severely abbreviated in length which allows greater sensitivity and a stronger condom more resistant to tearing during use than a conventional full length latex condom.

Abstract: Securement of a condom to the glans penis is facilitated by a molded, contoured, or thickened wedge portion which fits snugly within the cleft of the glans such that a continuous circumferential seal may be obtained about the glans penis. An expansible seminal reservoir is provided and the shaft of the penis, as well as the rear portion of the glans penis opposed to the cleft, may be left unsheathed in order to allow greater sensitivity. A greater wall thickness than that typically utilized in a full length condom may be used without significant loss of sensitivity and a stronger condom more resistant to tearing during use than a conventional full length latex condom is obtained. An adhesive backing with a tab allows location of the device prior removal of the backing to ensure correct positioning and an effective circumferential seal with the adhesive.
