Abstract: A dispensing valve is mounted in a dispensing aperture of a closure that has (1) a deck around the aperture, and (2) a hinged lid for closing over the aperture. The valve includes a marginal portion, a head portion with a discharge orifice therein, and a resilient, connector sleeve extending between the marginal portion to the head portion. The connector sleeve has a generally U-shaped cross-section that defines a first leg that is connected with the marginal portion and a shorter second leg connected with the head portion. The connector sleeve locates the head portion below the closed lid. An arcuate junction portion of the connector sleeve joins the first and second legs. The arcuate junction portion projects from the deck aperture when the lid is open. When the lid is closed, the arcuate junction portion is engaged and elastically deformed by the lid, and that prevents the valve orifice from opening.

Abstract: A press-control bottle stopper includes a hollow stopper shell fastened to the bottleneck of the body of a bottle, the stopper shell having an axial bottom hole and a water outlet for enabling liquid to pass out of the bottle, a hollow lining member mounted inside the stopper shell, the lining having a bottom center through hole axially aligned with the axial bottom hole on the stopper shell, a plug coupled to the bottom center through hole on the lining and axially moved to close/open the water outlet, spring means, which holds the plug in the close position, and control unit controlled by hand to move the plug between the close position and the open position.
