Medicine dispensing device with locking interaction between hatch and dividing wall

A medicine dispensing device, comprising:

• a base unit (1);
• a cassette (3) with a plurality of compartments (9) for storage of medicines which is rotatable relative to the base unit;
• means (20, 21, 22) for rotating the cassette (3) relative to the base unit (1) at predetermined times, a lid (15) firmly connected to the base unit (1);
• and
• an aperture (16) situated in the lid (15) in such a way that said aperture is movable to become central to any desired compartment (9) of the cassette (3) when the cassette (3) is rotated relative to the base unit (1) and the lid (15),
• wherein a hatch (17) is provided close to the aperture (16) and can assume a first position in which the aperture (16) is closed and a second position in which the aperture (16) is exposed,
• the hatch (17) being pivotable relative to a pivot axis (A-A),
• the hatch (17) having a rear edge (29) which has an extent in the circumferential direction of the device,
• the rear edge (29) being situated at a distance from the pivot axis of the hatch (17),
• and, when the hatch (17) closes the aperture (16), the rear edge (29) effects locking interaction with a radial first dividing wall (4) situated between neighbouring compartments (9).
