Abstract

The invention is a closure for the aperture of a pressure driven dispensing container. The closure includes (a) an outer shell having a planar base including an outer first main surface and an inner second main surface. The base includes a dispensing aperture fluidly connecting the outer surface to the inner surface and receives a dispensing tube. An outer peripheral skirt juts out of the inner surface and seals the closure to the aperture of the container. The closure also includes (b) a flexible valve in contact with the inner surface located within the outer peripheral skirt and defining an interior passageway having a first opening at one end adjacent to and in fluid communication with the first dispensing aperture and having a second opening at the other end of the passageway, wherein the flexible valve is resiliently biased so that it naturally shuts and seals the second opening.
