ABSTRACT:
A vacuum assisted condom applicator is provided made out of a suitable plastic material in the form of a rigid, or semirigid, double walled tube, open at one end and closed with a spherical cap on the other end to define an inner space. An internal space provided between the double walls of the tube and the cap is connected to the inner space by means of many small holes. A lower part of an outside wall surface of the invention is equipped with a normally closed membrane valve, which includes a push button release. The spherical top of the invention is equipped with a membrane valve which is closed and sealed by the factory at which a condom is prestretched and packed within the double walled tube. Each individual condom is factory prestretched and evenly lined along an inner surface of the double walled tube and held in place by a vacuum created in a space between the double walls of the tube. A large number of small holes allows for a sensitive application of the vacuum forces to the outer surface of the condom. The membrane valve button is then depressed to instantly allow air through the membrane valve button into the evacuated space between the double walls to thereby release the condom from the inner wall of the tube and thereafter remove the empty double walled tube.
