  • Patent number: 7278557
    Abstract: A pressure container is used for receiving viscous substances and has an outlet valve (14) which can be displaced between a closed position and an open position. A movable valve element (18) can be moved in the direction toward the interior of the container for unblocking an opening cross section. Since, on the one hand, a large opening cross section is desired and, on the other hand, it is necessary to overcome a very high initial resistance because of particles penetrating into the interior of the container, it is proposed to provide at least two opening cross sections which can be unblocked in sequence by actuating the valve. By means of this an initial small actuating force is achieved along with a still large opening cross section when the valve (14) is completely opened.

  • Publication number: 20060243754
    Abstract: A pressurised container (10) has an outlet valve with a sealing element (24) disposed in a sealing seat (22). If the viscosity of the container contents decreases below a limit value, it is provided that the sealing element (24) be detached from its sealing seat (22), so that it closes or substantially reduces an opening cross section, and a discharge of the container contents is avoided. The function of the outlet valve is furthermore improved by the provision of an actuating lever (30), which comprises two hinged parts (40, 42) and which for high-viscosity substances, particularly in the frozen state, reduces the actuating force to a practicable level.
