Abstract

L'invenzione concerne un tappo di sicurezza (1) per recipienti atti ad essere messi in pressione interna, che presenta:- un corpo di fissaggio (2) montato amovibile sul recipiente con una valvola (10) montata assialmente mobile, per effetto della pressione,- un mezzo di azionamento (22) associato alla valvola (10),- una calotta esterna (30) montata libera di ruotare sul corpo di fissaggio (2) in modo tale che nella sua posizione inferiore di battuta della valvola (10) la rotazione della calotta (30) causa quella del corpo di fissaggio (2), mentre in caso di sovrapressione, corrispondente alla posizione superiore di battuta, la calotta (30) è separata dal detto corpo, caratterizzato dal fatto che la valvola (10) è solidale ad un indicatore di pressione (51) atto a sporgere dalla calotta esterna (30) allorché la valvola è sostanzialmente in posizione superiore per costituire un indicatore visivo di sovrapressione.
