Abstract:
A plastic aerosol valve with a plastic valve stem, plastic housing, plastic mounting cup, and plastic locking ring. The plastic valve is assembled into the mounting cup. The plastic housing is assembled into the plastic mounting cup by snap fittings. The plastic mounting cup has a peripheral portion that snap fits up into the plastic locking ring. The plastic locking ring has frangibly-connected upper and lower portions. The lower portion snap fits with the top of a plastic product bottle to mount the aerosol valve assembly on the bottle. The upper ring portion thereafter is telescoped downwardly over the lower ring portion to lock and retain the aerosol valve assembly on the pressurized bottle. The plastic mounting cup can be molded separately, or integrally with the plastic locking ring. A check valve may be contained in the valve stem.
Abstract:
A vortex spray generating system that comprises a discharge channel and at least one inlet channel. The discharge channel and the at least one inlet channel are disposed with respect to one another such that the at least one inlet channel is capable of providing a tangential feed of fluid into the discharge channel sufficient to generate a vortex and spray pattern. A method of generating a vortex in a pressurized fluid so as to deliver the pressurized fluid as a spray. The method comprises providing a vortex spray generating apparatus comprising a discharge channel and at least one inlet channel, and introducing a tangential feed of fluid through the at least one inlet channel into the discharge channel sufficient to generate a vortex and spray pattern. The at least one inlet channel is disposed such that it is perpendicular to the discharge channel or angled with respect to the discharge channel.
