A child resistant dispensing closure having a pourout style spout that is telescopically mounted on a cylindrical extension of the closure. The closure is described with two embodiments of a push-pull spout. In both cases the closure threads onto a container finish and a pourout spout of the push-pull type is mounted on a cylindrical extension of the closure. The closure extension has a side opening adjacent the closed upper end through which the contents may be dispensed. The spout effectively closes the opening when in assembled form. Interengaging beads and lugs formed on the exterior of said closure and interior of said spout define the only relative rotational position that permits the spout being pulled up on the closure to uncover the opening therein. The proper rotational position is indicated when indicia on the spout and closure are aligned.

A child resistant dispensing closure in combination with a container having an externally threaded neck, comprising a closure with a threaded skirt and formed with a horizontal panel for sealingly engaging the top of the container neck when threaded thereon, an integrally formed annular, cylindrical member extending vertically from the center of said panel, a first outwardly extending radial bead adjacent the upper end of said cylindrical member and an inwardly and upwardly tapered annular area extending above the first bead on said cylindrical member, a round, horizontal top closing the upper end of said cylindrical member with a portion of said upwardly tapered annular area removed to provide a pourout opening communicating with the interior of the container via the cylindrical member, a second outwardly extending radial bead about said cylindrical member at a location above the horizontal panel of said closure but closer thereto than the first bead, a dispensing spout telescopically positioned over said cylindrical member, said spout having an inwardly extending annular bead overlying the second bead on said cylindrical member, interengaging means formed on said spout and said closure for preventing axial movement of said spout relative to said closure except at a single, relative circumferential position, said spout having an externally formed upper surface area adapted for grasping to facilitate pulling and rotating said spout on said cylindrical member, said spout having a top wall with a downwardly and outwardly tapered, inner annular surface adapted to seat on the upper end of said cylindrical member and the tapered area thereof and an opening formed in said top wall within which the round top of said cylindrical member seats with its upper surface substantially coplanar with the top wall of said spout, said spout is formed with a horizontal outwardly radially extending wall at the bottom thereof and a downwardly extending cylindrical skirt joined to the outer edge of said horizontal wall, with said horizontal wall overlying the panel of said closure and said skirt surrounding the skirt of said closure, interengaging ratchet and ramped groove means formed between said horizontal wall of said spout and the top wall of said closure for permitting relative rotation of said spout and closure in one direction only, and cooperating indicia means on said top wall of said spout and the round top of said cylindrical member for indicating when said spout is circumferentially aligned with said cylindrical member so that the spout may be axially moved relative to said cylindrical member.
