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.

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.

Abstract: A fluid dispenser for attachment between a water pipe and a shower head having a main stream water passage therethrough into which dispensed fluids flow through a port surrounded by a delivery manifold delivering the fluids from a reservoir assembly from which the fluids flow through valves, the outlet ports of the valves being cleaned to prevent clogging by water flowing past them which reaches them by flow from a bypass opening from the main stream passage upwardly through an in-flow compartment of the manifold which is separated from the out-flow compartment by a weir over which the water flows to direct it at the outlets of the valves, the reservoir assembly with its valves being removable from the delivery manifold for ease of refilling.
