(54)	Closure assembly with valve and method for its manufacturing

(57) A Self closing valve is made of a resilient material, in particular silicone rubber. The valve comprises a dome shaped central portion, which is provided with at least one through slit and which is inwardly concave when it is in an unloaded state. In the unloaded state the slit is closed and seals the inside of the container. The dome shaped central portion is deformable by pressure from the inside of the container to a convex shape in which the slit is open so as to allow dispensing of a substance from the container. The valve further comprises a skirt which extends downwardly from the peripheral edge of the central portion. On its lower end the skirt has an outwardly extending flange. At the transition between the dome shaed central portion and the skirt an annular groove is present.
