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. The inward flange of the outer member includes a taper portion tapering radially inward away from the base portion, such that insertion of the insert into the outer member causes the taper portion of the insert to progressively outwardly expand the inward flange of the outer member to assist assembly thereof.
