Abstract
A pill crusher with a pivotable hammer which applies pressure to the tablets when a press applies pressure to the hammer enables a user to quickly and securely crush tablets. The hammer and the press are pivotally connected to opposing ends of a body which has a crushing recess. Tablets are sandwiched between cups which are disposed in a crushing bowl. The crushing bowl is rotatably and removably located in the crushing recess. The hammer has a crushing head configured to be pivoted into the rotatable crushing bowl. The crushing head has a crushing surface configured with a pattern of alternating recessed portions and raised portions. The press is eccentrically connected and a lever extends eccentrically from the press.
Claims49
An apparatus for crushing compressible tablets comprising:
- a body means for receiving crushable tablets, the body means having a hammer end opposite a press end, the body having a crushing recess between the hammer end and the press end configured to receive crushable tablets;
- a hammer means for crushing tablets, the hammer means having a pivot end opposite a bearing end, the pivot end of the hammer means being pivotally connected to the hammer end of the body means, the hammer means being pivotable to a loading position to enable crushable tablets to be loaded into the crushing recess of the body means, the hammer means having a crushing head located between the pivot end and the bearing end of the hammer means, the crushing head being configured for insertion into the crushing recess of the body means when the hammer means is pivoted into a contact position such the crushing head is in contact with crushable tablets placed in the crushing recess, the crushing head being configured for urging against crushable tablets placed in the crushing recess to crush the tablets when sufficient pressure is applied;
- a press means for pressing against the bearing end of the hammer means, the press means being pivotally connected to the press end of the body means, the press means having a contact portion configured to press against the bearing end of the hammer means when the hammer means is in the contact position, the press means being configured such that pivoting the press means into a compression position enables the contact portion to be urged against the bearing end of the hammer means and such that pivoting the press means to a released position releases the hammer means to pivot between the loading position and the contact position;
- and
- a lever means for moving the press means between the released position and the compression position, the lever means extending from the press means.

An apparatus for crushing compressible tablets comprising:
- a base having a hammer end opposite an attachment end, the base having a crushing recess between the hammer end and the press end;
- two opposing support arms having a bottom end opposite a top end, the bottom end of each of the two opposing support arms being attached to the attachment end of the base;
- a crushing bowl having an exterior surface configured to be removably and rotatably positioned in the crushing recess of the base, an interior surface configured to receive crushable tablets, and a rim which rests above the crushing recess,
- a hammer having a pivot end opposite a bearing end, the pivot end of the hammer being pivotally connected to the hammer end of the base, the hammer being pivotable to a loading position to enable crushable tablets to be loaded into the crushing recess of the base, the hammer having a crushing head located between the pivot end and the bearing end of the hammer, the crushing head being configured for insertion into the crushing recess of the base when the hammer is pivoted into a contact position such the crushing head is in contact with crushable tablets placed in the crushing recess, the crushing head being configured for urging against crushable tablets placed in the crushing recess to crush the tablets when sufficient pressure is applied;
- a press pivotally connected to the top ends of the two opposing support arms such that the press pivots eccentrically, the press having a contact portion configured to press against the bearing end of the hammer when the hammer is in the contact position, the press being configured such that pivoting the press into a compression position enables the contact portion to be urged against the bearing end of the hammer and such that pivoting the press to a released position releases the hammer to pivot between the loading position and the contact position;
- and
- a lever extending from the press to move the press between the released position and the compression position.
