ABSTRACT:
Disclosed are closure mechanism for the open-neck of manually resiliently squeezable receptacles permitting fluids of a wide viscosity range to be dispersed 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 for the receptacle open-neck and having an outlet-opening; an elongate spindle within the receptacle along the central-axis thereof, the spindle remote of the cap having a trailward-length provided with a circumferential discontinuity type fulcrum and also with a preferably trailwardly convergent shoulder contactable by the manually squeezed receptacle to move the spindle directionally normal to the central-axis; clampably mounted trailwardly of the cap outlet-opening, a centrally-open and stretchable gasket constrictably surrounding the spindle leadward-length; and an adapter separable from the cap but having a longitudinally arrested relationship thereto, the adapter having a fluid-pervious reticulated trailward-skirt pivotably connected to the spindle trailward-length fulcrum and also having a medial flange extending in sealing relationship between the cap and the receptacle open-neck.
