A grinder device is provided. The grinder device may include a container, a cap assembly configured to be friction-fit to the container such that the cap assembly is removably lockable to the container, and a grinding mill disposed within the cap assembly to perform a grinding operation of condiment disposed in the container. The grinding mill may include a movable grinder portion and a fixed grinder portion that are rotatable relative to each other, and the fixed grinder portion is engagable with the container to permit relative rotation between the cap assembly and the container.

A condiment dispenser (10) with a grinding mechanism (28) according to the present invention comprises: a first part (26) defining an aperture (24) and surrounding inner surface (32), both with lobed cross-sectional profiles; and a second part (36) that is inside the first part (26) and can rotate about an axis (16) relative to the first part (26). The second part (36) has an outer surface (42) and the second part (36) and outer surface (42) both have lobed cross-sectional profiles. The inner surface (32) of the first part (26) and the outer surface (42) of the second part (36) are spaced apart by a gap (38) which is larger at a receiving side (48) of the grinding mechanism (28) and narrows in the axial direction towards a dispensing side (50) of the grinding mechanism (28).
