ABSTRACT:
A non-aerosol pressure dispenser includes a pressurization chamber having a piston reciprocable therein and a manual actuator extends from outside the chamber into operative association with the piston. The actuator is reciprocable in a first direction to move the piston to compress a spring engaged therewith and to draw material into the chamber. The spring urges the piston in a second direction to pressurize the material in the chamber and a discharge valve or nozzle is connected with the chamber to release the pressurized contents thereof over a desired prolonged period of time and at a sufficient pressure to obtain a fine mist of the material.
