Abstract
A push-pull dispensing cap is described for a container having an open-necked top. There is a first cap member, attachable to an open-necked container, which has an outside thread for engagement with threading of an overcap, and has an upwardly projecting hollow portion with at least one dispensing port. It also is slideably attached to a second cap member such that the second cap member may cyclically moved with a first, closed position being downward, and a second, open position being upward. The second cap member has a dispensing port thereon and has an outwardly projecting ridge thereon with a cut-out located on the ridge to permit passage therethrough of a protrusion located inside the overcap. The second cap member is attached to the first cap member so as to prevent any of substantial horizontal rotation of it relative to the first cap member. The overcap is adapted to fit over the second cap member, has a top and a sidewall, has internal threading adapted to thread with the outside of the first cap member.
