Herb grinder system
First Claim
1. An herb grinder system comprising:
- a tubular housing member including an internal bore, an outer surface, a top surface and a bottom surface, a lower portion of said internal bore having internal engaging structures for attachment of a first lower grinding plate;
said first lower grinding plate including a plate portion having an upper surface, a lower surface and an outer perimeter surface, said outer perimeter surface having conjugate engaging structures for cooperation with said internal engaging structures to secure said first lower grinding plate at a substantially perpendicular orientation with respect to said internal bore at a position below said top surface of said tubular housing member and to prevent unwanted rotation thereof, said upper surface of said first lower grinding plate having a plurality of upstanding blades integrally formed to said upper surface of said plate portion, said plate portion having a plurality of sized apertures positioned proximate to said upstanding blades and extending through said plate portion;
an upper grinding plate assembly, said upper grinding plate assembly including an upper surface, a lower surface, an outer diameter surface and a pilot portion, said pilot portion sized and shaped to fit within an upper portion of said internal bore while allowing rotation of said upper grinding plate assembly with respect to said tubular housing member, said lower surface of said upper grinding plate assembly including a plurality of outwardly extending blades positioned to pass between said upstanding blades of said lower grinding plate when said upper grinding plate is rotated;
a rotatable surface for positioning said upper grinding plate assembly with respect to a top portion of said internal bore of said tubular housing member including a plurality of burnishing rings separated by debris rings, said debris rings having a smaller diameter than said burnishing rings;
a bottom cap member, said bottom cap member having an outer perimeter surface, a top surface and a bottom surface, said outer perimeter surface having conjugate engaging structures for cooperation with said internal engaging structures within said tubular housing member to secure said bottom cap member at a substantially perpendicular orientation with respect to said internal bore at a position juxtaposed to said lower surface of said tubular housing member having a gap between said top surface of said bottom cap member and said lower surface of said lower grinding plate.

Abstract
The present invention involves a system and method for grinding herbs, tobacco, marijuana and the like. The herb grinder system herein includes interchangeable and replaceable lower grinder plates that are secured in place with threading, bayonet mounts or the like. The upper and lower grinding plates are provided with blades having a modified diamond shape which provides extremely sharp leading edges regardless of which direction the grip assembly of the grinder housing is rotated. The lower plates are also provided with variations in the size, shape and arrangement of hole sizes through which the ground material is allowed to pass through. This construction provides the user with the ability to control his/her grind size mixture, which may be consistent sized grinds or a mixture of different sized grinds.
