ABSTRACT:
A two-piece, non-spurting dispensing closure for a bottle or other appropriate container of the type having a finish or neck. The closure comprises a shell for engagement with the neck or finish of the bottle or container. The shell has an upstanding cylindrical chimney and a pair of upstanding diametrically opposed posts to either side of and spaced from the chimney. A tip is rotatively and telescopically mounted on the chimney and is shiftable between an extended open position and a retracted closed position. The interior of the tip is provided with a pair of thread segments and a pair of inclined planes, one thread segment and one inclined plane of each pair cooperating with one of the shell posts to serve as an elevating and lowering mechanism apart from the chimney to shift the tip between its open and closed positions upon limited rotation of the tip with respect to the shell. The interior of the tip also has stops to positively define the open and closed positions of the tip. The engagement of the shell with the neck or finish of the bottle or container may be such as to prevent removal of the shell from the neck or finish. The thread segments may be configured to render the closure tip child-resistant. The entire closure may be provided with an overcap.
