<p>A pressure container used to receive viscous substances, provided with an outlet valve (14) which can be moved between a closed and an open position. A moveable valve element (18) can be displaced towards the inside of the container in order to release the opening cross-section. Since a large opening diameter is desired and a very high initial resistance must be overcome as a result of the large size of the parts entering the interior of the container, at least two opening cross-sections which can be successively released by actuating the valve are provided. A low initial actuating force is thus obtained while the opening cross-section remains large and the valve (14) is fully opened.</p> |
