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. One of the lower end parts of the two members embraces the lower end part of the other member, and one of the two members can be inserted in the mounting of the container lid. At least the head part and the foot part of the entire enveloping member consist of elastically flexible material which is deformable in radial as well as in axial direction with respect to a central longitudinal axis of the mandrel member. The head part of the enveloping member surrounds the tip part of the mandrel member and is snugly and sealingly fitted thereon in closed position.
