Abstract

This relates to a press-seal type transfer neck finish for a container wherein the neck finish is provided with an annular recess into which there is snapped a fitment which carries the thread elements for a threaded closure. In order to facilitate closing of a container which has been filled with the product to be packaged, the closure is assembled with a fitment having thread elements cooperating with the thread of the closure. Thus the resultant closure unit may be applied to the container by merely downwardly pressing the closure unit onto the container. In the formation of the fitment thread elements, openings are formed in a lower flange of the fitment through which tiny insects and foreign matter may enter into the space between the closure skirt and the fitment. These openings are sealed by fin segments or flaps molded in one piece with the fitment and being swingable to underlie the fitment flange in sealed relation in alignment with the openings. Also the bead of the container neck finish is provided with recessed seats to receive in interlocking relation the fin segments or flaps to lock the fitment against rotation relative to the container neck finish.
