摘要:
A push body valve closure to dispense product retained in a container. The closure includes a base affixed to the mouth of the container and a cap cooperatively engaged upon the base and movable between a first closed position and a second opened position with respect to the base. The base is formed with a product dispensing channel having a wall with a generally conical-shaped cross-sectional configuration and the cap has a depending spring-action circumferential flange formed on the interior surface thereof for cooperative engagement with the conical-shaped wall. The cap is normally disposed in its closed position but is movable to the open position upon application of a force thereon to move the cap with the spring-action circumferential flange engaged against the conical-shaped wall. Upon removal of the force applied to the cap, the cap returns to its closed position by the force of the spring-action flange against the conical-shaped wall.
