Abstract
A tube assembly for medicament and the like wherein the contents can be discharged by squeezing the tube. The tube assembly includes a nozzle having a discharge port and an axial central bore with a diaphragm extending across the bore at the inner end of the discharge port. A piercer unit mounted in the nozzle portion is mounted for axial movement in the central bore from a first readily position, axially inwardly of the thin wall, to a second discharge position puncturing the diaphragm. The assembly further includes a cap having a support plug sized in the discharge port for abutment against the diaphragm and to prevent inadvertent puncture thereof. The piercer unit includes a hollow needlelike member adapted for movement axially in the central bore and a piston for mounting the hollow needlelike member slidably in the nozzle portion for actuating the needlelike member from the first position to the second position upon application of external pressure, such as squeezing pressure applied to the tube.
