METHOD AND APPARATUS FOR SPRAYING A METERED QUANTITY OF A SEMI-LIQUID PRODUCT

Spray dispensing of a metered quantity of a preferably semi-liquid product from a filled container having a fixed wall (28) provided with at least one and preferably a plurality of generally open and unobstructed discharge passageways (30). A moveable wall (32) spaced apart from the fixed wall (28)...

Beschreibung
Zusammenfassung:	Spray dispensing of a metered quantity of a preferably semi-liquid product from a filled container having a fixed wall (28) provided with at least one and preferably a plurality of generally open and unobstructed discharge passageways (30). A moveable wall (32) spaced apart from the fixed wall (28) is impacted with a moving mass to induce a pressure pulse in the product sufficient to surge a metered quantity of product less than the entire content of the container through the generally open and unobstructed discharge passageways (30) with sufficient velocity as to break away from the passageways (30) and the remaining product within the container for ballistic travel generally normal the fixed wall (28) outwardly of the container. A plurality of uniform discharge passageways (30) and a proper match of product formulation and energy input produces a generally uniformly moving cluster of generally uniformly defined and moving particles.
