ABSTRACT:
A valve is provided with a peripheral attachment portion by which the valve may be attached to a dispensing structure through which can be discharged a product from a supply of the product. The valve includes a flexible, peripheral sleeve extending from the peripheral attachment portion. The sleeve has a central elongate portion and two shorter end portions at opposite ends of the elongate portion so that the central elongate portion and the two shorter end portions together define an interior volume. The valve also has a flexible, elongate head extending from the peripheral sleeve. The head includes at least one elongate slit defining two, opposed, elongate, openable regions in the head which are normally closed and which open to permit the discharge of the product therethrough in response to a pressure differential across the head.
