  • Patent number: 8870108
    Abstract: A spice grinder 14 is disclosed which comprises a first static component 12 including means for attaching it to a container 10, and a second rotatable component 16 which fits on the first component 12. The first component 12 has a tapering bore 26 with teeth 28 projecting inwardly from the surface of the bore 26, and the second component 16 has a toothed portion 44 in the bore. Grinding takes place in the gap between the teeth 28 44 of the components 12 16 when the second component 16 is rotated with respect to the first component 12. The second component 16 includes a transverse closure partition 34 with a set of openings 42 in it through which ground spice falls from the grinder 14 when it is in an inverted position, and a tamper evident closure component 54 seals off the openings 42. The grinder 14 can also include a stop element 88 secured to the second component 16. The stop element 88 encounters the first component 12 if an attempt is made to pull the second component 16 of the first component 12.
