ABSTRACT:
A child-resistant closure member adapted to be threadedly fastened onto the neck of a container is formed of a deformable material and has a top and an integral peripheral skirt on the inwardly facing surface of which screw threads are formed to allow the closure member to be rotatably screwed onto the container neck. A locking member having a locking portion is integrally formed with the closure member so as to be movable between a first position wherein the locking portion extends into the interior space defined by the skirt and a second position wherein the locking portion is withdrawn from the interior space. In a preferred embodiment, the locking member is constituted by a segment of the peripheral skirt itself and a radial segment of the closure top which is integral with and forms a continuation of the peripheral skirt segment. The locking portion extends into a slot formed in the neck of the container when the locking member is in the first position to prevent rotation of the closure member with respect to the neck of the container.
