ABSTRACT:
A spice grinder (12) comprising a first, static component (10) which includes threading (14) by means of which it can be screwed onto the threaded neck of a container and a second, rotatable component (16) which fits on the component (10). The first component (10) has a tapering bore with teeth (30) projecting inwardly from the surface of the bore. The second component (16) has a cone (44) with teeth (48) on the outside thereof. The teeth (48) are in the tapering bore whereby grinding takes place in the gap between the teeth of the first and second components upon the second component being rotated. The first and second component (10, 16) have interlocking circumferentially extending ribs and grooves (32, 50, 52) which permit the rotatable component (16) to be moved axially and located in its adjusted position thereby to vary the size of the gap between the teeth (30) of the rotatable component and the teeth (48) of the static component.
