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.
A two-piece, non-spurting dispensing closure for a container of the type having a finish, said closure comprising a shell and a tip, said shell having a top portion and an annular skirt for surrounding said container finish, means for attaching said skirt to said container finish, an upstanding cylindrical chimney being located centrally of said top portion of said shell, said chimney having a dispensing passageway extending axially therethrough and through said top portion of said shell, a cylindrical plug, means for supporting said plug axially and at the upper end of said chimney so as to extend thereabove, a pair of upstanding diametrically opposed posts located on said top portion of said shell to either side of and spaced from said chimney, each of said posts having a thread-receiving groove opening away from said chimney, said tip comprising a top portion and a downwardly depending skirt portion, said top portion of said tip having a dispensing opening located centrally thereof and passing therethrough, said tip having a cylindrical wall surrounding said dispensing opening and depending downwardly from said top portion thereof, said cylindrical wall surrounding said shell chimney and having an inside diameter so sized as to be rotatable about and axially shiftable with respect to said shell chimney, a pair of diametrically opposed inclined planes to either side of said cylindrical wall, each of said inclined planes contacting an upper edge of one of said shell posts, a pair of thread segments located on diametrically opposed inside surface portions of said tip skirt, each of said thread segments paralleling and being spaced from one of said inclined planes and being engaged in said groove of one of said shell posts whereby when said tip is twisted relative to said shell in one direction each of said shell posts cooperates with its respective tip thread segment and inclined plane to elevate said tip with respect to said shell from a retracted closed position wherein said plug is located in and closes said tip dispensing opening to an extended open position wherein said plug is withdrawn from said tip dispensing opening and when said tip is twisted relative to said shell in an opposite direction each of said posts cooperates with its respective thread segment and inclined plane to lower said tip with respect to said shell from said extended open position to said retracted closed position.
