ABSTRACT:
A convertible child resistant closure for use with a container having a threaded portion adjacent the container opening, e.g. the container neck, to allow a user to select between a child resistant closure and an easily openable closure depending upon the use and contents of the container. The closure includes coaxial inner and outer caps. The inner cap is defined by a cover wall and a side wall or skirt depending from the cover wall. The side wall includes an inner surface having a threaded portion for engagement with the threaded neck portion of the container, and an outer surface including a child resistant portion comprising a series of angular abutments extending thereabout and a non-child resistant portion axially offset from said child resistant portion and preferably in the form of a row of longitudinally extending knurlings. The outer cap is also defined by a cover wall and a side wall depending from the cover wall. The side wall includes an inner surface divided into a first child resistant portion and a second non-child resistant portion axially offset from the first portion. The first portion includes a plurality of angular abutment surfaces complementary to the series of angular abutments on the inner cap and the second portion includes a row of longitudinal knurlings complementary to the knurlings on the inner cap. The inner cap member is positioned within the second cap member and is axially movable between a first position in which the angular surfaces of the inner cap engage the angular abutment surfaces on the outer cap to provide a child resistant closure and a second position in which the knurlings on the outer surface of the inner cap engage the knurlings on the inner surface of the outer cap to provide a non-child resistant closure.
