ABSTRACT OF THE DISCLOSURE A removable closure for a pressure container having an opening with a peripheral bead into which there is inserted a threaded neck member, the neck member being formed of a resil- ient plastic material adapted to expand and contract and having an interlocking engagement with the bead. The neck is provided with a radially extending handle portion by means of which the container is adapted to be carried and which also serves to prevent rotation of the neck member upon the applica- tion and threading of a cap to the neck member, the cap having a plug portion which enters into the opening in the neck member and being tapered wedges into the neck member and spreads the portion of the neck member which is in radial alignment with the bead portion, thus tightly forcing such portion against the bead to provide a high pressure seal. The plug portion is provided with pressure relief grooves at its inner end extending axially of the plus such that as the cap is being unscrewed from the neck portion, the grooves are positioned to communicate the interior of the container with a space between the interior of the neck and the plug outwardly of the interlocking portion so that the excess pressure can bleed off to the atmosphere about the threads. The invention also comprises novel pilfer-proof mechanism which has to be broken away from the cap in order to unscrew the cap and there- fore readily is indicative of tampering.
