  • Patent number: 6024247
    Abstract: Solid dosage forms of pharmaceuticals, e.g. tablets, may be removed from blister packs with a deblistering machine. The machine has a roller and a stationary plate. The roller has a longitudinal axis of rotation and means for rotating the roller about the axis. The roller has an inner core and a cover thereon with a non-slip surface. The stationary plate has at least as many slots as there are columns of blisters, and each of the slots has a width parallel to the rotational axis of the roller, the width of each slot being at least as large as the width of a blister. Each of the slots has a length transverse to the slot's width and is at least as large as the length of a blister. The plate is situated to provide a throat, between the cover and the plate, into which the blister pack may be fed and through which the blister pack may pass as a result of rotation of the roller. The plate has a guide to ensure that each column of blisters is aligned with corresponding slots.
