ABSTRACT:
The invention relates to improved end closures for a dispensing container. One end closure is a nonmetallic thermoplastic plunger end closure which is comprised of a retaining member and a plunger member which are connected along a fragmentation line. The plunger end closure is assembled to the container body by the retaining member during shipment. Upon use, the plunger is separated from the retaining member along the fragmentation line. The other end closure is a diffusing end closure for dispensing and diffusing material from the container. The diffusing end closure is comprised of a ring member which is affixed to the container and a diffusion disk which is bonded to the ring member. The diffusing disk includes at least three diffusing orifices.
