ABSTRACT:
A self-contained grinding device, for pepper corns and the like, includes only three molded plastic elements and can be attached to a suitable container which stores the material to be ground. The device includes two cylindrical housings which are end connected to form a rotary joint and an elongate gear member which has a grinding head portion which cooperates with a grinding chamber formed in a first housing remote from the container. The gear member has a shaft portion with a bifurcated end which extends from the first housing into a second housing connected to the container. The gear member is fixed to the second housing by a snap-fitting engagement of the bifurcated free end with a transverse bridge arm which is integrally formed with the second housing. The bridge arm is additionally connected to a hopper wall similarly integrally formed with the second housing, which hopper wall feeds the pepper corns from the container to the grinding chamber in the first housing. The second housing includes projections suitable for engaging the external threads of the container such as a jar. The gear member is a grinding element as well as a means for maintaining the three elements of the grinding device together both when connected or disconnected from the storage container. A projection is advantageously provided in the grinding chamber which cooperates with the grinding head portion to ensure effective grinding action of the pepper corns which reach the grinding chamber.
