ABSTRACT:
A claw closure for a plastic threaded nipple on an extruded plastic canister is tiltably carried by an external metallic collar on the nipple. The metallic collar carries a lid with a ring seal held between inner and outer flanges on the lid bottom. An internal ring in the nipple has a radial flange over the threaded nipple and is integral with the external collar. The internal ring has an axial internal thread for 20 liter canisters. The radial faces of the collar and the internal ring are aligned and set off from each other by an annular groove into which the inner flange of the lid bottom extends. An axial venting hole is provided in the wall region of the internal ring.
