ES288595U - Precinct cap for botanical gas bottles (Machine-translation by Google Translate, not legally binding) - Google Patents

Abstract

Seal cap for bottles of butane gas, which is provided for application on the mouth of a bottle, which logically is mounted on the outlet valve, is characterized essentially because it is constituted by a cap of plastic material whose closed base presents internally and in the axial and concentric direction, an appendix configured in a special way for its adaptation to the nozzle of the valve corresponding to the embouchure of the bottle; it being provided that said cap has a trunco-conical upper section that is continued, after a staggering, in another truncated-conical section of greater diameter and length, this second section being affected in the direction of its generatrices of equally spaced openings between that determine as many flexible fins determine the lateral surface of said section, each fin in correspondence with its lower edge with an internal projection in the circumferential direction for its anchoring and retention on the mouth of the bottle, while externally said fins they have a groove, also in the circumferential direction, together determining an annular groove interrupted only by the separating openings of the fins themselves, and in whose groove a ring will be placed that will press the fins inwards preventing the extraction of the cap when it is coupled and retained a at the mouth of the bottle, with the particularity that said ring is linked to an external one by means of radial and tear-off appendages, said second ring constituting the means of pulling to produce the tearing of said appendages, as well as the breaking of the ring internal and consequently the unsealing of the plug.
