A dispensing package is provided for fluid products such as liquid soaps, shampoos and conditioners, household detergents, cleaners, polishes, moisturizing creams, and the like, and includes a container with a self-sealing dispensing valve mounted therein. The valve includes a marginal flange, a valve head with a discharge orifice therein, and a connector sleeve having one end connected with the valve flange and the opposite end connected with the valve head adjacent a marginal edge thereof. The connector sleeve has a resiliently flexible construction, such that when pressure within the container raises above a predetermined amount, the valve head shifts outwardly in a manner which causes the connector sleeve to double over and extend rollingly.

[ What is claimed is:] [1.]1. A dispensing valve for fluid product packaging of the type having a container with a discharge opening therein, comprising:a marginal valve portion shaped to seal about the discharge opening of the container;a valve head portion, having an orifice which opens and closes to control fluid flow, and being shaped to shift generally centrally in an axial direction with respect to said marginal valve portion; anda connector sleeve portion, having one marginal end area thereof connected with said marginal valve portion, an opposite end area thereof connected with said valve head portion, and a resiliently flexible construction that stretches in an axial direction to apply radially inwardly directed forces to said valve head portion which assist in securely retaining said orifice fully closed as said valve head shifts axially prior to dispensing.
