ABSTRACT:
A dispenser for liquids, including a supporting chassis, a supply tank for the liquid, a pump and a nozzle for conveying the liquid to the user of the dispenser. The nozzle has a housing member with an internal passage extending therethrough and has an insert and associated compressively elastically deformable sleeve positioned within. The insert has a passage extending from an opening in one end to at least one side opening, and the sleeve is interposed between the housing member and the inert with the portion of the sleeve adjacent the housing member being related against radially outward deflection by the housing member. The portion of the sleeve adjacent the insert encases the portion of the insert having the side opening to normally seal the side opening and thus prevent the liquid from leaking out of the nozzle. When the pump is actuated, the liquid compressively elastically deforms the portion of the sleeve adjacent the insert so that the sleeve is forced away from the insert side opening, and the liquid flows into the insert passage through the insert end opening, through the insert passage, out of the insert passage through the insert side opening, past the sleeve and out of the housing member passage.
