A base attachable to a supporting surface, and a food container mountable on the base. The latter and the container have telescoping medial portions. A stud with a side lug depends from the container into the base and engages either one of a pair of cams therein when the container is given a partial side turn in the corresponding direction, whereby to hold the container down on the base. An element in the latter is tensioned by this action to maintain the hold on the container.
