Abstract

Abstract Disclosed are closure mechanism for the open-neck of manually resiliently squeezable receptacles permitting liquid to be dispensed through the open-neck only so long as manual pressure is being exerted against a visually indicated portion of the receptacle deflectable wall. The dispensing closure mechanism generally includes: a cap secured to the open-neck and having a leadward outlet-opening; a longitudinally extending and movable spindle and preferably having a shoulder attached thereto inside the receptacle; and a yieldable seat for the spindle such as a resiliently stretchable gasket secured to the cap and constrictably surrounding the spindle. Accordingly, maintenance of manual pressure against the receptacle deflectable wall moves the spindle causing fluid dispensing such as via the gasket central-opening. Novel optional features include special shields overlying the cap, specially contoured and/or visually marked receptacle walls, various yieldable seats for the spindle, etc.
