Tablet pulverizer

A hand-operated tablet pulverizer for crushing solid tablets into fine particles comprising:

• a tablet container having a closed end forming a pestle and an open mouth at the other end, the closed end having a peripheral end means;
• a mortar having internal thread means for complimentary engagement with the peripheral thread means of the container for moving the pestle into engagement with the mortar upon relative rotation thereof in one direction to crush a tablet interposed therebetween;
• and
• a plurality of protrusions on at least one of said pestle and mortar projecting toward the other of the pestle and mortar, the protrusions including a base portion, the protrusions being arranged in a pattern of generally perpendicularly intersecting, generally parallel lines and parallel columns, the protrusions in the lines being substantially equally spaced, and the protrusions in the columns being substantially equally spaced and equal to the spacing of the protrusions in the lines thereof, and the base of one protrusion being substantially aligned with the bases of adjacent protrusions.

A hand-operated pulverizer for crushing solid materials into fine particles, comprising:

• a container having a closed end forming a pestle and an open mouth at the other end, the closed end having peripheral thread means;
• a mortar having internal thread means for complementary engagement with the peripheral thread means of the container for moving the pestle into engagement with the mortar upon relative rotation of the mortar and pestle with respect to the other of the mortar and pestle about an axis of relative rotation to crush solid material interposed therebetween;
• and
• a plurality of protrusions on at least one of said pestle and mortar projecting toward the other of the pestle and mortar, the protrusions being arranged in a pattern of intersecting lines and columns, the pattern being eccentric relative to the axis of relative rotation.
