  • Patent number: 5489050
    Abstract: A three piece closure for selectively controlling flow of product from a container, and method of manufacture, are disclosed. The closure includes an inner member, an outer member and an insert disposed therebetween. The inner member is adapted for attachment to a necked opening of the container. The outer member has a base portion, a top portion, and an inward flange disposed substantially circumferentially about the base of the outer member. The insert has a base portion and a radially outward flange disposed substantially circumferentially about the base portion. Upon insertion of the insert into the outer member, the outward flange passes the inward flange to provide cooperative engagement with the inward flange such that axial movement of the outer member causes axial movement of the insert to control the flow of the product.
