ABSTRACT:
A pill crusher having a rack and pinion advancing a platen. Pill crushers are used to crush pills into powder for various medicinal reasons, such as ease of mixing or dosing. A rack on a slide way is linearly advanced by rotational movement of a pinion on a handle. The slide way is attached to a platen that advances towards an anvil. A pill in a pouch placed adjacent the anvil is crushed by the advancing platen. In one embodiment, a shaped anvil insert surface is mated to a complementary shaped platen surface and aids in crushing the pill. The present invention provides an efficient and sturdy pill crusher for commercial as well as personal use.
