2129109 9315994 PCTABS00025 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 (180) connecting a ring (170) to a body (140) so that the ring (170) is axially offset from, but concentric with, the cylindrical wall of the body (140). Subsequently, the frangible webs (180) are broken, and the ring (170) is moved axially to a location concentric with the body cylindrical wall to form the assembled closure. In the assembled closure the body (140) has a closed end (150) and an open end suitable for mounting on a container. The cylindrical wall of the body (140) defines a discharge passage (154) for communicating with the container for dispensing the contents thereof. The ring (170) defines a dispensing orifice (178) and accommodates rotation between a dispensing position in which the passage (154) and orifice are at least partially aligned and a closed position in which the passage (154) is occluded by the ring (170). |
