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.
An implement for applying liquid includes an elastic container for containing liquid, a head cylinder connected to the elastic container, and a liquid applying member in the head cylinder for applying liquid to a surface, the elastic container having in an opening thereof a valve assembly for supplying and blocking liquid from the elastic container to the head cylinder and pressing portions in the sides thereof, the valve assembly being actuated by pressing the pressing portions. The elastic container includes an oval cylindrical portion having an elliptical cross section consisting of short arcuate portions and long arcuate portions, the long arcuate portions having actuators in the form of inward projected recesses at central portions thereof respectively for acting as pressing portions, the valve assembly including a valve rod carrying a slide member having a tapered surface, the slide member being disposed between the two actuators.
Apparatus for dispensing predetermined amounts of viscous product. The apparatus has a conduit which is telescopically received with a cap. The cap and conduit define an expandable dosing chamber which expands to a predetermined maximum volume when product is introduced into the chamber through the conduit. A check valve prevents back flow of product through the conduit. Collapsing the chamber from its maximum volume to a minimum volume dispenses the product from the dosing chamber.
A valve operating mechanism comprises a valve having a valve member and a valve seat, the valve seat having a fluid passage hole is arranged at an end of a fluid chamber containing fluid such as liquid or gas, the valve member which is axially moved relative to the valve seat, to thereby control the passage of fluid, an axially movable member spaced a certain distance from the valve seat, radially displaceable members such as thread-shaped members, linear members or bar-shaped members through which the axially movable member is interconnected with a rear part of the body, and means for causing, when a grasping force is applied to the radially displaceable members the valve seat moves relative to the valve member, thus opening the valve, and for causing, when the grasping force is eliminated, the valve seat comes into abutment against the valve member, thus closing the valve.
