a spindle nut 12 which likewise is made of a plastic material and comprises arms 13 14 and whose ends carry a ring 15 provided with two cutting edges 16 17 engages the spindle 10 in order to rotate the spindle nut and accordingly simultaneously rotate and lift the cutting edges 16 17 an activating device 18 is provided which comprises a peg 19 which is supported in an axial bore of the spindle 10 moreover the activating device is constructed as a ring 20 which can easily be grasped with one hand for the purpose of rotating while the other hand holds the multiple compartment container the ring 20 encloses a portion of the lower portion which has a smaller radius a circumferentially extending shoulder 21 is accordingly formed on which the ring 20 is supported this and a corresponding construction of the lower edge of the ring 20 ensure that the multiple compartment container stands securely in order to prevent the ring 20 from axial movement during its rotation the rotationally locking connection between the peg 19 and the spindle nut 12 e g in the form of a rectangle or hexagon is constructed so as to be axially displaceable in addition the activating.
