Abstract
A self-sealing closure assembly including a base having threads for attachment to a plastic flexible container. The base includes one passage therethrough and an axially extending stem. A flexible disc is provided on the base and has a central opening through which the stem extends into normally sealing relation with the central portion. An overcap including a base wall and a skirt is telescoped over the flexible disc and interengages the base for holding the flexible disc in sealing relation with the base and overcap. The overcap has an opening through which the stem and the central portion of the disc extend. When the closure assembly is placed on a container having squeezable walls and the container is squeezed, the central portion of the flexible disc is moved out of sealing relation with the stem to permit the contents to be dispensed. When the squeezing force is removed, the central portion of the flexible disc returns to sealing relation with the stem.
