摘要

Stopper for closing gas cylinders improved, which is constituted by a hollow body, as a flattened cap (1) which is characterized because internally comprises, in combination: a) a central neck (2) with helical projections on its outside, concentric to the peripheral skirt of the hollow body (1). B) a metal capsule (5) containing a core of elastic material (4) that rests directly on the upper edge of the neck (3) of the valve of the cylinder, with which it establishes a closing arrangement. C) an alignment of nerves or projections (9) regularly distributed in the interior wall of the hollow body (1) whose ribs terminate in a cylindrical sector (8) which laterally supports the neck (7) of the valve of the bottle.
