Abstract
A child-resistant package comprising a container having an exteriorly threaded finish portion, and a closure comprising an inner cap member having a top panel integrally formed with a depending skirt portion having threads formed on the interior surface thereof for engagement with the finish portion of the container, and an outer member having a peripheral skirt portion surrounding the skirt portion of the inner cap member. Interengaging members between the inner cap member and the outer closure member are operable upon relative axial movement between the members to interengage the members such that rotation of the outer member will also rotate the inner member to disengage the threads of the inner member from the threads of the container. A tamper-indicating member comprising an annular ring has portions extending between the lower edge of the skirt portion of the outer closure member and a portion of the container which are operable to prevent axial movement of the outer closure member relative to the inner closure member.
