ABSTRACT:
An all-plastic closure for snap-fit attachment to a raised neck finish of a plastic container for closing the container includes a unitary dispensing spout, a threaded closing cap, and a unitary outer ring which is attached to the closing cap by a plurality of frangible elements. The neck finish of the container has a substantially cylindrical inner surface defining a container opening wherein the upper outer edge of the neck finish is configured with an outwardly extending lip portion and a recessed area therebeneath which is used for interlocking and snap-fit engagement with the all-plastic closure. The dispensing spout is moveable back and forth between a nested position and an extended position and includes an outer flange with annular inner and outer walls which are joined by an upper wall and which together define an inverted annular channel. The unitary outer ring is assembled onto and around the outer flange with a snap-fit arrangement. The annular channel of the outer flange is designed to snap over and around the raised neck finish whereby the annular inner and outer walls are sized relative to the raised neck so as to create a compressive fit against the raised neck for establishing a liquid-tight interface between the closure and the container. The closure is made tamper-evident by the presence of the frangible elements.
