  • System comprising a container having a slit valve as a venting valve and a liquid contained in said container
    Patent number: 5390805
    Abstract: In a system comprising a container and a liquid contained therein that builds up a gas or vapor pressure, a sealing valve having a concave shaped portion and a slit extending through said portion, allows venting of the vapor from the container to the ambient at a predetermined vapor threshold pressure. The vapor threshold pressure at which the slit opens for venting can be adjusted by valve restraining means which are preferably formed by a protrusion at the inside of a cap covering the sealing valve. The vapor threshold pressure at which venting takes place, can to a large extent be adjusted without affecting the dispensing characteristics of the valve.
