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.

Abstract: A disposable package dispenser comprises a replaceable, collapsible, prefilled package of the product to be dispensed, and includes a product discharge member and attachment structure for releasably attaching the package to a pressurizable dispensing container. The container includes a manually operable expansible chamber to pressurize the interior of the container and thus the collapsible product containing package to collapse the package and effect pressurized discharge of the product when the discharge member is operated.
