发明名称 Spice grinder
摘要 A spice grinder comprising a bottle (60) and a grinder unit (10) which is screwed onto the bottle. The grinder unit comprises a fixed component (12) and a rotatable component (14). The components have teeth (28, 44) which face one another across a grinding gap (52). The component (12) has one or more ramps (54) on the inside thereof and the bottle (60) has one or more external ramps (66). Each ramp (54) comprises a camming surface (56) and a locking surface (58) which intersect. The ramp (66) also comprises a camming surface (68) and a locking surface (70). When the grinder unit (10) is screwed onto the bottle the ramps (54, 66) ride over one another until the surfaces (56, 70) clear one another and the surfaces (58, 70) snap into face-to-face contact to prevent the grinder unit being rotated in the direction which unscrews it from the bottle.
