International ClassB65D 50/04AbstractA reversible child-resistant closure system including a closure and container. The closure has a child resistant mode when applied to the container in a first child-resistant position and has a non-child resistant mode when applied to the container in a second non-child resistant position. The closure includes an outer cap and an inner cap. The inner cap is coaxially positioned and nested within the outer cap such that a plurality of angular abutment surfaces of the inner cap engage a series of angular abutments of the outer cap upon rotation of the outer cap to rotate the inner cap in a closing direction. However, upon rotation of the outer cap member in an opening direction in the absence of an axial force, the angular abutment surfaces of the inner cap cam over and past the series of angular abutments of the outer cap, preventing rotation of the inner cap.Field of SearchCombined or convertibleClosure removal obstacle movable to unobstructive position Encompassing closure removal obstacle and closure engaging for concurrent movement Axially movable closure removal obstacle or obstacle portion Closure threaded to receptacle and/or rotatable closure removal obstruction Flexible locking member integral with or attached to closure Closure guided in simultaneous turning and reciprocating movememnt (e.g., screw threaded) Including visual indicia Cap-type fastener With means to prevent unintentional rotation in closure releasing direction Projection engages keeper to stop rotation in closure applying direction Receptacle opening sealed by each of plural closures | |
