Abstract

A child resistant cap and tube assembly including a tube for containing a product and having an end portion with a recessed thin wall section puncturable to provide a discharge opening and a shoulder for limiting axial movement on the end portion. The cap has a central axis for alignment with the tube to slidably engage it. A piercer is normally spaced from the thin wall section in a first position and operable to puncture the thin wall upon movement of the cap to a second position. On the cap is formed a shoulder engaging portion for preventing movement to the second position without it being intentionally manipulated to a shoulder disengaging position. This portion may comprise a skirt detatchably attached to the end of the cap to prevent movement of the cap to the second position until the skirt is removed. Alternatively, this portion may comprise a ring and groove with the piercer being located on the other end of the cap whereby the intentional manipulation includes disengagement of the ring and groove. In still another alternative, the portion comprises a boss and socket, the socket being normally out of alignment with the boss and the intentional manipulation includes aligning the boss and socket.
