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.

Abstract: A drip resistant dispensing valve for fluids is disclosed, which provides a dispensing outlet configured to minimize the tendency for fluid to drip from the valve following a dispensing operation. The dispensing outlet exhibits curved interior surfaces and a curved outlet face construction; the face situated a distance away from the valve body. Such construction assists in minimizing the retention of fluid on the surfaces of the dispensing outlet, and migration of the fluid to surfaces outside of the dispensing outlet that could tend to promote growth of biological contaminates and/or provide additional surfaces that could pool fluid following a dispensing operation and thereafter drip from the valve. A shell is provided around the dispensing outlet to assist in avoiding contamination of the valve and of the fluid being dispensed through the valve, and to aid in positioning a receptacle for receiving fluid from the dispensing valve.
