Abstract: A filling valve mechanism for cans is presented. The valve includes a sleeve slidably mounted on a pair of pins and limited in downward motion by means of a stop. The sleeve carries an O-ring circumferentially thereabout for engaging within the throat of a container or can to be filled. The O-ring is of slightly greater diameter than the throat of the can such that sealing engagement is achieved. Also carried on the sleeve is a resilient compressible stripping member adapted for engaging the mouth of the can. The stripping member compresses against the mouth of the can, short of full compression by virtue of the limited downward movement of the sleeve against the stop. After the can is filled, the stripping member urges the O-ring from the throat of the can while holding the can in place.
