Patent ID: 8720747

Claim:
A dispensing device for dispensing compressed fluids from a can through a valve stem of the can, the dispensing device comprising: (a) a hollow tube defining a channel entirely through the tube from an entrance end to an opposing dispensing end; (b) a connector defining a conduit there-through with one end of the conduit mating with the channel of the hollow tube to provide fluid communication through the conduit and channel and where the opposing end of the conduit is designed to attach to the valve stem of the can; (c) a plug located in and able to move within the channel of the hollow tube, wherein the plug mates with the hollow tube in a sealing configuration that seals the channel from fluid flow when the plug is pressed towards the dispensing end of the hollow tube; and (d) a sleeve that wraps at least partially around the hollow tube and having 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 and thereby allows fluid communication from the channel through the dispensing end of the hollow tube; wherein the dispensing device is free of a spring that applies a force on an object to seal the hollow tube at the dispensing end.
