  • Patent number: 6705592
    Abstract: The invention relates to a closure for a container to be pressurized, comprising a housing to be fixed to the container, in which a passage is present, whilst a seat is arranged in said passage, which seat is intended to mate with a closing element, which is urged in the direction of the seat by means of a coil spring surrounding said closing element, said the coil spring being confined between a part of the closing element and a few spaced-apart projections formed in one piece with the housing, which are connected to the remaining part of the housing by means of a few spaced-apart arms, said coil spring and said projections being capable of resilient deformation relative to each other, in such a manner that the spring can be moved past the projections in its position of use.

  • Patent number: 6089415
    Abstract: A valve for a keg of beer comprises a neck ring to be secured to the container and an inner part formed with a valve member, which fits an opening of the neck ring. A locking mechanism functions to lock the inner part in the neck ring, and a sealing ring forms a seal between the inner part and the neck ring at the location of opposite seat portions in the neck ring and the inner part. The inner part and the neck ring are provided with mutually cooperating coupling mechanisms, which, after the locking mechanisms have been released, provide for the removal of the inner part from the neck ring in two steps, wherein pressure relief takes place in the first step via at least one pressure relief opening. The pressure relief opening is formed through the wall of the neck ring, at a location a small distance above the seat portion in the neck ring, so as to effect a reliable pressure relief.
