Multiple core retention elements are provided to transfer core tablets from the bowl top to the press turntable. A method for using the apparatus is also provided.
Claims18
An internal feed wheel assembly for a tablet press assembly, comprising:
- a base portion;
- a tablet insert chute coupled to said base portion and having an exit aperture;
- a bowl top rotatably coupled to said base portion, said bowl top having an upper surface, a lower surface and an inner periphery, a plurality of notches disposed on said lower surface and in communication with said inner periphery, and a first set of a plurality of apertures extending through said upper surface and in communication with said plurality of notches;
- wherein said exit aperture of said tablet insert chute is positioned proximal to said inner periphery of said bowl top;
- wherein each of said plurality of notches is geometrically dimensioned to receive a single tablet.
An internal feed wheel assembly for a tablet press assembly, comprising:
- a base portion having a tablet trap;
- a tablet insert chute coupled to said base portion and having an exit aperture;
- a bowl top rotatably coupled to said base portion, said bowl top having an upper surface, a lower surface and an inner periphery, a plurality of notches disposed on said lower surface and in communication with said inner periphery, and a first set of a plurality of apertures extending through said upper surface and in communication with said plurality of notches;
- wherein said tablet trap is positioned proximal to said inner periphery of said bowl top;
- wherein said tablet insert chute exit aperture is located proximal to both said tablet trap and said inner periphery of said bowl top.
A tablet press assembly comprising:
- a first base portion, and a second base portion;
- a tablet insert chute coupled to said first base portion and having an exit aperture;
- a bowl top rotatably coupled to said first base portion, said bowl top having an upper surface, a lower surface and an inner periphery, a plurality of notches disposed on said lower surface and in communication with said inner periphery, and a first set of a plurality of apertures extending through said upper surface and in communication with said plurality of notches;
- a press turntable rotatably mounted to said second base portion;
- said press turn table comprising a plurality of upper punches, a plurality of lower punches, and a second set of a plurality of apertures, wherein one of said plurality of said upper punches and a corresponding one of said plurality of lower punches and a corresponding aperture of said second set of a plurality of apertures are substantially collinear with one another;
- a plurality of core retention elements, each adapted to move between at least a first position proximal to said bowl top and a second position proximal to said press turntable
