Spice Grinder

摘要

A grinder has a jar having a surface provided with a screwthread. A grinding cap has a lower part engageable over the surface of the jar and provided with a screwthread such that the lower part can be screwed onto the jar and an upper part rotatable on the lower part. Grinding formations on the parts are effective on relative rotation of the parts. A ramp projects radially from the jar surface toward the cap surface, and a generally angularly extending and radially elastically deflectable arm has an inner end fixed on the cap surface and an outer end spaced in a relaxed condition of the arm radially outward from the cap surface toward the jar surface. The arm is oriented to engage and have its outer end deflected radially toward the cap surface by the ramp on screwing of the lower part onto the jar.

主权项

1. A grinder comprising:
a vessel designed to hold a material to be ground and having a vessel surface centered on an axis and provided with a screwthread formation; and a grinding cap having:
a lower part engageable into or over the vessel surface and provided with a screwthread formation complementary to the formation of the vessel surface such that the lower part can be screwed to the vessel upon rotation of the lower part in relation to the vessel;an upper part rotatable on the lower part; andgrinding formations on the upper and lower parts effective on relative rotation of the lower and upper parts to grind the material of the vessel; a blocking system that blocks counter-rotation of the lower part in relation to the vessel, said blocking system comprising:
a blocking formation; andan elastically deflectable arm;the blocking formation and the elastically deflectable arm being fixed upon and extending from respective different ones of radially spaced-apart surfaces comprised of a surface of the lower part of the cap and a surface of the vessel;the elastically deflectable arm having a length extending between a surface-fixed end and a non-fixed outer end, the elastically deflectable arm being oriented to engage and have the outer end deflected by the blocking formation during screwing of the lower part of the cap onto the vessel.
