Abstract: A cartridge for a closure, and a closure containing such a cartridge, are provided for accommodating the dispensing of a liquid product from a container. The cartridge includes a body, a valve seated in the body, and a retainer engaged with the body to hold the retainer and body in a clamping relationship retaining the valve in position on the body. A standardized valve and overall cartridge design may be employed with a variety of different closure housings for different containers.

Abstract: A unitary article is provided in a form which can be reconfigured as a two-piece dispensing closure. According to the method, the unitary article is molded with frangible webs connecting a ring to a body so that the ring is axially offset from, but concentric with, the cylindrical wall of the body. Subsequently, the frangible webs are broken, and the ring is moved axially to a location concentric with the body cylindrical wall to form the assembled closure. In the assembled closure the body has a closed end and an open end suitable for mounting on a container. The cylindrical wall of the body defines a discharge passage for communicating with the container for dispensing the contents thereof. The ring defines a dispensing orifice and accommodates rotation between a dispensing position in which the passage and orifice are at least partially aligned and a closed position in which the passage is occluded by the ring.
