ABSTRACT:
A glass container is molded with a recessed outlet end having a sharp outer edge and an enlarged lip. The outside surfaces of the lip of the container from a point adjacent the recessed opening are straight in part and convexly shaped in another part and terminate in a portion of reduced diameter at the neck of the container. A closure assembly centrally housing an aerosol "or pump-type" valve is formed with a depending flange, an annular stepped portion adjoining the central housing, and a concave surface portion connecting the stepped portion and the depending flange. A liquid elastomeric resin lining is flowed onto the concave surface and depending flange portions and cured to form a resilient liner. The closure assembly is then mounted upon the recessed open end of the glass container forming an inwardly diverging channel between the recessed outlet and enlarged lip of the container on the one hand and the stepped and concave portions of the closure assembly on the other hand. The closure assembly is then secured to the container by the crimping or rolling of the depending flange. This action causes the sharp edge to bite into the elastomeric lining, compresses the resilient lining, causing it to flow in the diverging channel toward the recessed opening of the container and fill the channel, and seals the container. The closure assembly can also be used with a metal bottle and will form a continuous structure with the top edge thereof permitting a simple container structure whose edges will not be deformed when crimped.
