Abstract
A dispensing device for dispensing compressed fluid from a can through a valve stem of the can has a hollow tube with a channel extending through it from an entrance end to an opposing dispensing end, a connector defining a conduit therethrough that is in fluid communication with the channel of the hollow tube and that attaches to a valve stem of a can, a plug located within the channel of the hollow tube that forms a sealing configuration within the channel when pressed towards the dispensing end of the channel, and a sleeve that wraps at least partially around the hollow tube and that has a protrusion that upon activating the sleeve extends through the dispensing end of the hollow tube and prevents the plug from establishing a sealing configuration with the hollow tube.
