<p>The present invention relates to a non-aerosol dispenser. The problem associated with aerosol dispensers is that many contain hydrocarbons which contribute to air pollution. The non-aerosol dispenser comprises an inner cylinder (224) defining a material chamber (211) with a discharge valve (214) at one end. A piston assembly (220) for pressurizing the contents carries a cutting edge (288, 289) and guides (280, 281). Outer housing (240) receives the guides (280, 281) which advances the piston (220) upon rotation of the housing (240) while forcing the cutting edge (288, 289) to cut through the inner cylinder (224). The piston (220) includes an energizer member (252). An ejector (250) and spring is disposed between the energizer (252) and the valve (214). The spring stores energy from advancement of the piston (220) and transmits such to the ejector (250).</p> |
