Abstract
A child resistant cap and tube assembly with a tube for containing a product and having an end portion terminating in an axially centered open surface at its outer perimeter and having a recessed thin wall below the surface to seal the tube. The tube has a second surface of interference to axial movement on the end which is a predetermined distance from the perimeter. A cap is also provided, having a central axis for alignment with the tube and sized to slidably engage the end portion. The cap also has a resistance surface for engaging the surface of interference at a predetermined distance to locate the cap on the end portion at a first position to protect the recessed thin wall. The cap has an axially centered puncture means positioned inside said cap to puncture the recessed thin wall upon movement of the cap to a second position for opening the tube. Finally, the surface of interference and the resistance surface are positioned to cooperatively resist movement of the cap to the second position with a force sufficient to prevent inadvertent movement to that second position.
