摘要
A single dose dispensing device for aspirating a product located in a replaceable container by means of compressed air is disclosed. The device includes a piston-cylinder assembly having a movable member and a fixed member and has a compressed air flow path therethrough with an aperture at the free end of the fixed member. A product dispensing member, also having a compressed air flow path therethrough is connected to the piston-cylinder assembly, the respective compressed air flow paths being in communication with one another. The dispensing member further includes a product storing chamber and an aspirating means in communication with both the product storing chamber and the compressed air flow path. A diaphragm member normally blocks the compressed air flow path and is adapted to open when the movable member substantially completes a compression stroke, thus allowing product to be dispensed by means of compressed air.
