Abstract:
Improvements in valve heads for bottles of the kind which may be coupled to the neck of a bottle containing carbonated liquid, including:a) a valve body crossed by a liquid circulation channel communicating an outer spout with the inner outlet of a dip tube which ends inside the bottle;b) a check valve which, mounted in said circulation channel, has a normally closed valve blocker the stem of which has a sliding guide in the upper portion of said valve body;characterized by comprising:c) a covering hood having substantially a frustoconical shape, the upper portion of said valve body fitting into the larger open base, while the partially closed smaller base has a diametrical slot the ends of which, exceeding said smaller base, pass through part of the side walls of said covering hood;d) a command means which, connected to said valve blocker, and having its fulcrum at the side walls of said covering hood, constitutes a second genus lever the resistance of which is given by a compression resilient means, while the power is given by an articulated arm foldable within the limits of said covering hood and unfoldable through said diametrical slot;e) a removable band which, partially blocking said diametrical slot, constitutes a folding strap for said foldable articulated arm;f) a mouth which, affecting the side walls of said covering hood, constitutes a passage for said outer spout; and connecting means between said hood and said valve body.
