Abstract

A child resistant cap and tube assembly, comprising 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. A cap is provided having a central axis for alignment with the tube and sized to slidably engage the end portion. An axially centered puncture is positioned to be aligned with the thin wall section and 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 for opening the discharge opening. The cap further includes a shoulder for preventing axial movement of the cap from the first position to the second position without intentional manipulation of the shoulder to a shoulder disengaging position. The shoulder comprises a skirt detachably attached to the tube engaging end of the cap, the skirt engaging the shoulder to prevent movement of the cap to the second position until the skirt is removed. The shoulder comprises a boss located on the end portion and the shoulder comprises a socket on the cap. The socket is normally out of alignment with the boss to define the first position and the intentional manipulation includes aligning the boss and the socket to permit movement of the cap to the second position.
