Abstract: A container for a fluid under pressure, preferably a beer keg, including a neck and a fitting mounted thereon with a suction tube for drawing the fluid into the container. A pressure relief valve is mounted in an upper end of the suction tube or in the neck of the container. The pressure relief valve includes a closing body which is mounted resiliently via a spring and movable from a closing position to an open position by the spring being compressed.

Abstract: Plastic container, particularly for storing liquid under pressure, comprising an integrally formed body with a bottom, an upright substantially cylindrical side wall and an upper side with a neck having a bottom end and an open top end in which a closing element of the container can be mounted, wherein the upper side of the container, around the neck, is formed with at least one shoulder and at least one valley which runs downward in radial direction from the neck in the direction of the upright side wall; wherein each shoulder protrudes upward relative to the at least one valley; which at least one shoulder and at least one valley are formed integrally with the body of the container.
