Tablet breaking device

Claim 2

A tablet breaking device comprising a base member having a top surface and means for holding a tablet at an angle of about 5° to about 70° relative to the top surface and for restricting downward movement of the tablet, wherein a portion of the tablet extends in an inclined cantilevered position beyond the top surface; a tablet splitting edge in the base member under the tablet about which a moment of force sufficient to break the tablet can be created by applying a force substantially normal to a portion of the tablet extending beyond the top surface; a cavity in the base member for receiving a broken portion of the tablet; and tablet breaking means rotatable over the top surface for exerting the force substantially normal to the tablet; wherein the tablet breaking means covers the cavity, but not the tablet holding means, after the tablet is broken; wherein the tablet holding means comprises an elongated linear opening having a tapering depth, which increases from a minimum depth at one end of the opening to a maximum depth at the other end of the opening, and a length sufficient for the tablet to be moved along the length thereof while said downward movement of the tablet is restricted to permit breaking the tablet into different proportions in a single breaking step.

Claim 3

Tablet breaking device according to claim 1 wherein the opening tapers in depth and width and the taper is such that the depth of the elongated opening diminishes as the width of said opening diminishes.

Claim 4

Tablet breaking device according to claim 1 comprising tablet breaking means rotatable over the top surface for contacting the tablet proximate the outer edge of the portion of the tablet extending beyond the top surface, wherein said rotatable breaking means has a surface beyond the outer edge of the tablet, wherein the breaking force is applied to said surface of the breaking means.

Claim 5

Tablet breaking device according to claim 1 having tablet holding means for a multiplicity of tablets in side-by-side arrangement and providing cantilevered tablet segments of different lengths; wherein the tablet breaking means is capable of simultaneously exerting tablet breaking forces on all the tablets.

Claim 6

Tablet breaking device according to claim 1 including tablet breaking means hinged at one side of the top surface for exerting a force substantially normal to the portion of the tablet extending beyond the top surface to thereby create a moment of force about the splitting edge sufficient to break the tablet.

Claim 7

A tablet breaking device comprising a base member having a top surface and means for holding a tablet at an angle of about 5° to about 70° relative to the top surface and for restricting downward movement of the tablet such that a portion of the tablet extends in an inclined cantilevered position beyond the top surface; a tablet splitting edge in the base member under the tablet about which a moment of force sufficient to break the tablet can be created by applying a force substantially normal to the portion of the tablet extending beyond the top surface; a cavity in the base member for receiving a broken portion of the tablet; and tablet breaking means rotatable over the top surface for exerting the force substantially normal to the tablet; wherein the tablet holding means comprises an elongated linear opening having a tapering depth, which increases from a minimum depth at one end of the opening to a maximum depth at the other end of the opening, and a length sufficient for the tablet to be moved along the length thereof while said downward movement of the tablet is restricted to permit breaking the tablet into different proportions in a single breaking step; and wherein the tablet holding means substantially prevents rotation of the tablet about the tablet splitting edge when the force is applied and the tablet breaking means covers the cavity, but not the tablet holding means, after the tablet is broken.

Claim 8

A tablet breaking device comprising a base member having a top surface and means for holding a tablet at an angle of about 5° to about 70° relative to the top surface and for restricting downward movement of the tablet such that a portion of the tablet extends in an inclined cantilevered position beyond the top surface; a tablet splitting edge in the base member under the tablet about which a moment of force sufficient to break the tablet can be created by applying a force substantially normal to the portion of the tablet extending beyond the top surface; a cavity in the base member for receiving a broken portion of the tablet; and tablet breaking means rotatable over the top surface for exerting the force substantially normal to the tablet; wherein the tablet holding means comprises an elongated linear opening having a tapering depth, which increases from a minimum depth at one end of the opening to a maximum depth at the other end of the opening, and a length sufficient for the tablet to be moved along the length thereof while said downward movement of the tablet is restricted to permit breaking the tablet into different proportions in a single breaking step; and wherein the tablet holding means substantially prevents rotation of the tablet about the tablet splitting edge when the force is applied and the tablet breaking means covers the cavity, but not the tablet holding means, after the tablet is broken.

Claim 9

Tablet breaking device according to claim 6 wherein the taper is such that the depth of the elongated opening diminishes as the width of said opening diminishes.

Claim 10

Tablet breaking device according to claim 6 having tablet holding means for a multiplicity of tablets in side-by-side arrangement and providing cantilevered segments of different lengths; wherein the tablet breaking means is capable of simultaneously exerting tablet breaking forces on all the tablets.

Claim 11

Tablet breaking device according to claim 6 including tablet breaking means hinged at one side of the top surface for exerting a force substantially normal to the portion of the tablet extending beyond the top surface to thereby create a moment of force about the splitting edge sufficient to break the tablet.

Claim 12

Tablet breaking device according to claim 6 having tablet holding means for a multiplicity of tablets in side-by-side arrangement and providing cantilevered tablet segments of different lengths; wherein the tablet breaking means is capable of simultaneously exerting tablet breaking forces on all the tablets.

Claim 13

Tablet breaking device according to claim 6 wherein the channel tapers in dimension along the splitting edge to break a tablet along a diagonal breakline.

Claim 14

Tablet breaking device according to claim 6 comprising a tablet breaking means rotatable over the top surface for contacting the tablet proximate the outer edge of the portion of the tablet extending beyond the top surface, wherein said rotatable breaking means has a surface beyond the outer edge of the tablet and wherein the breaking force is applied to said surface of the breaking means.
