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.
