Liquid dispenser for an inverted container

Abstract:

The invention relates to a liquid dispenser for dispensing liquid from an inverted container. The dispenser includes a body adapted for releasably engaging to the inventor container, a valve localized in the body and defining a dispensing orifice that reacts to pressure differences for dispensing liquid to the exterior atmosphere, and an impact resistance system. The impact resistance system is located upstream of the valve and includes a housing that includes a cavity adapted to be occupied by a compressible substance. The compressible substance allows pressure equilibration between the valve interior side and the valve exterior side allowing the dispensing orifice to be reactively closeable, especially to absorb a hydraulic hammer pressure from an impact force.
