ABSTRACT:
A contraceptive device formed of elastic material includes an extensible cap-shaped element having folds in the form of a bellows. The integral base of the element extends outwardly in the form of a planar annular flange having attached to the outer border thereof a rigid ring. The area of juncture between the cap and flange is defined by a plurality of apertures or perforations, whereby slight pressure exerted on the ring allows separation of the flange from the cap. The lower edge of the interior of the cap has applied thereto an adhesive band for adhering the cap to the glans of a male organ.
