Abstract: A cover (1) has a base (2) to which a vessel (5) can be nonrotatably attached and a cap (3) which is rotatable relative to the base (2) and has, via a gear (4) arranged in the cover (1) and having a transmission ratio of 4:1, an operative connection to a shaft (6) which is rotatably mounted in the vessel (5) and carries two blades (7a,b) which are staggered axially relatively to one another and are provided in each case with cutting edges (8) on both longitudinal edges. After the vessel has been filled with material to be cut and has been connected, the apparatus can be picked up and tilted and used for uniform comminution of material to be cut, in particular vegetables, by mutual rotation of the vessel (5) and of the base (2), on the one hand, and of the cap (3), on the other hand, with alternately opposite directions of rotation. It is particularly suitable for uniform cutting of onions into small cubes.

Abstract: A manually drivable apparatus for comminuting foods. The apparatus includes a substantially rotationally symmetrical vessel configured to receive a material to be cut, a substantially rotationally symmetrical removable cover configured to nonrotatably mount on the vessel, a shaft rotatably mounted centrally along an axis of the vessel, and at least one blade mounted to the shaft and projecting approximately at right angles from the shaft. The apparatus includes a cutting edge provided on the at least one blade on each of a first longitudinal edge and a second longitudinal edge opposite the first longitudinal edge. The apparatus includes a rotatable drive part configured to drive at least the shaft, and includes a gear arranged in the cover and configured to operatively connect the rotatable drive part to the shaft with a transmission ratio that is greater than 1.
