Abstract
The present invention provides a springless diaphragm which is adapted to be inserted into a vaginal vault for birth control and which comprises a resilient rim member composed of a first flexible material, and a dome member which is composed of a second flexible material. The rim member is securely bonded to the dome member and extends continuously thereabout along the lower perimeter thereof. The dome member is provided in its uppermost portion with a substantially thicker portion in order to permit formation of the device without danger of rupture during the molding process. The first flexible material and the second flexible material are required to have Durometers within specified ranges, and the rim member may be further provided with opposing outwardly projecting sections in order to enhance the spring modulus of the rim member upon flexing of this portion of the diaphragm prior to insertion.
