Abstract
A rechargeable applicator for dispensing substances especially substances in a foam or foam-like condition including dispensing them into body cavities or elsewhere, the applicator includes a pressurized container having one end which is normally closed by a valve and filled with a substance under pressure for dispensing therefrom, and cooperatively associated with the container is an expandable chamber into which some of the contents of the container can be expelled in a foam or foam-like condition when the container is withdrawn but not separated from the chamber, the container thereafter serving as a plunger for expelling the contents of the chamber into a body cavity or elsewhere where the substance is to be used.
