Abstract
A dispensing valve is provided for dispensing a product from a container. 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 so that a plane passing through the head portion extends generally through or outwardly of the marginal portion.
