  • Patent number: 5169076
    Abstract: A crusher comprises a housing defining a crushing chamber for restraining an object to be crushed and a plunger for applying force on the object to be crushed when the plunger is actuated by a handle. The handle is mounted on the housing for pivotal movement about a first floating pivot in a first pivotal direction which actuates a first engaging element to move the plunger in a first direction to crush the object in the crushing chamber. The plunger is locked against resilient return in a second direction by a second engaging element. Further pivotal movement of the handle about a second floating pivot in a second pivotal direction actuates the disengagement of the second engaging element, causing the return of the plunger.

  • Patent number: 4967971
    Abstract: The present pestle and mortar for crushing pills in pill cups is tailored to conform to the shape of a pill cup. A conventional frustum-shaped pill cup lines a frustum-shaped receptacle in the mortar to receive a frustum-shaped pill crushing portion of the pestle which is nestable in the pill cup. The frustum-shaped crushing portions of the pestle and mortar distribute pressure over much of the exterior and interior surface areas of a pill cup so that pills may be crushed in even fragile paper pill cups without tearing or otherwise damaging the paper pill cups. Moreover, the pill cup and mortar operate as one piece and the frustum-shaped crushing portion of the pestle substantially seals the interior of the pill cup to prevent pill granules from flying out of the pill cup during a pill crushing operation.
