Also provided is a cap having a first end with an inside cross section sized to engage the nozzle and having an axially centered puncture spike positioned in a first position spaced from the thin wall and movable to a second position to puncture the thin wall. The puncture spike has a chisel shaped edge for forming a hole in the wall and a central bore for providing access to the contents of the tube. The cap has a second enclosing an applicator for dispensing the contents of the tube, whereby the contents of the tube is transferred to the applicator through the bore of the puncture means.
