<p>The invention relates to a bottle top with valve mainly for the sealing of carbonated drink bottles which has a cylindrical part, a pouring opening and sealing components, characterised by that there is a cup (10) seated in the internal space (1b) of the house (1) delimited by the house cylindrical part (1a), a sealing body (9) is placed in the cup (10), the sealing body (9) has a head (9a), neck (9b) and stem (9d), and a disc (9c) inserted in between these latter two, the neck (9b) and stem (9d) of the sealing body (9) are coaxial with each other and with the longitudinal axis (1d) of the house (1), a spherical valve body (11) that operates like a ball joint rests on the head (9a) of the sealing body (9), the head (9a) of the sealing body (9) fits to the valve body (11) along the slot (11a) established in the surface of the valve body (11), there is an axle (12) threaded through the valve body (11) concentrically, both ends of the axle (12) can be lifted away from in front of the cylindrical part (1a) of the house (1), and so the valve body (11) can be moved along the conical frustum shaped valve seating (3a) of the supporting body (3) and though this is embedded in the operating tongue (2) making a free path for the liquid to be poured from the bottle, in the internal collar (1c) of the house (1) there is an outlet channel (6a), while in the bottom (10a) of the cup (10) there are a passage openings (6b), the sealing body (9) stem )9d) is surrounded by a spring (8) that is up against the bottom (10a) of the cup (10), on the completion of the pouring the spring (8) blocks the path of the liquid by pushing the sealing body (9) disc (9c) up against the outlet channel (6a).</p> |
