Abstract:
A nozzle mechanism for an aerosol-type dispenser for dispensing liquid content by application of pressure, comprising:a flexible nozzle portion having an outlet portion for dispensing said liquid content said outlet portion having a wall thickness which decreases from a first point along a direction of elongated axis of symmetry of said nozzle mechanism toward a tip of the flexible nozzle portion;a first normally-closed valve within the outlet portion for controlling flow through said outlet portion; anda swirling chamber within said flexible nozzle portion for temporarily housing said liquid content prior to expulsion via said outlet portion;wherein said liquid in said chamber is expelled via said first normally-closed valve upon reaching a threshold pressure sufficient to sequentially and radially open segments of said first normally-closed valve along said elongated axis of symmetry of said nozzle mechanism, whereby an initial segment of said valve opened is substantially closed when a final segment of said valve is open.
