Abstract:
1. 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 having opposing entrance and dispensing ends, the hollow tube defining a channel entirely through the tube from the entrance end to the 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 capable of attaching 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 and hollow tube mate in a sealing configuration that seals the channel from fluid flow when the plug is pressed towards the dispensing end of the hollow tube; (d) a flexible and inelastic extension piece having opposing first and second ends with the first end attached to the plug, the extension piece extending through at least part of the channel of the hollow tube and optionally through at least part of the connector conduit; and (e) a sealed port defined in the hollow tube, the connector or both and through which the flexible and inelastic extension piece extends from inside the channel or conduit to outside of the dispensing device; wherein the second end of the flexible and inelastic extension piece is attachable to the can, and wherein the extension piece is long enough so that when the connector is attached to the valve stem of a can the plug can be in a sealing configuration when the extension piece is attached to the can but short enough so that when the connector and valve stem are tilted away from the extension piece with respect to the can the plug is unable to be in its sealing configuration, and wherein the dispensing device is free of a spring that presses the plug into sealing configuration.
