Abstract: A self-sealing actuating device is adapted for being mounted on the valve-body of a conventional pressurized container valve from which liquid product is dispensed with a propellant, in liquid, pasty or foamy condition. The device opens automatically when an external part thereof is moved, and comprises(a) as said external part, an actuating tube having a discharge orifice;(b) an obturating member lodged stationary in a tubular passage of the actuating tube, having an obturating head obturating the discharge orifice from the outside, and(c) a spring device biassing the actuating tube toward closed position when the actuating device is opened; when the actuating tube is moved toward open position, the obturating head frees the discharge orifice with the compression of the spring device.

Abstract: A self-closing tilting valve which is insertable in a valve mounting provided in the lid of a container filled with product under pressure, comprises a substantially rigid mandrel member having a base part and a tip part, and an enveloping member surrounding said mandrel member and having a foot part and a head part with an outlet opening. At least one passageway for product from the container leads along the mandrel member to the outlet opening, and at least one obturating face is provided on the inner wall of the enveloping member and a corresponding counter-face on the mandrel member in the region of said passageway, contact between said obturating face and said counter-face obturating said passageway in closed position. The tip part of said mandrel member and the head part of said enveloping member bear contact faces remaining in contact with each other during closed as well as during open position.
