A push valve dispensing closure including a base mountable to the mouth of a container, a valve mounted within the base and a cap cooperatively engaged upon the base for rotational movement of the valve relative to the base between locked and unlocked positions, and, in the unlocked position, between a first closed position and a second open 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 valve has depending spring-action circumferential flange segments formed thereon for cooperative engagement with the conical-shaped wall. The cap includes a discharge orifice closed by a panel on the valve with rotation of the cap relative to the valve, after movement of the valve to the unlocked position, opening the orifice.

[ What is claimed is:] [1.]1. A dispensing closure comprising, a base adapted to be secured to the mouth of a container for product to be dispensed therefrom, a valve engaged upon the base and movable with respect thereto between a first closed position and a second open position, a product dispensing channel formed in the base for communication with the container mouth, said channel having an aperture therein through which the product may be dispensed, said channel having a wall and a portion of the wall being of generally conical-shaped cross-sectional configuration, said valve including spring-action circumferential flange means for cooperative engagement with the conical-shaped wall portion of the channel, the valve having a through-passage formed therein in alignment with said channel for product discharge therethrough from said channel to the exterior of the closure, and a dispensing plug secured to the valve at a location which is in registry with the through-passage, said plug being positioned to be in cooperative engagement with the channel aperture in the base when the valve is disposed in said first closed position with respect to said base to preclude product discharge, said closure including cooperative means between said valve and base to lock and unlock same and thereby prevent the valve from inadvertently being moved between its first closed position and its second open position, said closure including an externally manipulable cap overlying the valve, cooperating means on the cap and valve for retaining the cap on the valve for movement of the valve between the closed and open positions, and to lock and unlock the valve and base relative to each other, upon manipulation of the cap.
