Claim:
1. A combination storage and grinding device, the device comprising: a compartment defined by a first compartment end and a second compartment end from which extend compartment sidewalls defined by a compartment diameter, the compartment further defined by a cavity; a first lid defined by a first interior portion and a first exterior portion, the first interior portion having a plurality of first grinding members, the first exterior portion having a first lid end from which extends a first lid sidewall, the first lid sidewall defined by a first lid diameter, the first lid diameter configured to be infinitesimally smaller or larger than the compartment diameter, the first lid disposed to detachably mate with the first compartment end, wherein an airtight seal forms between the compartment sidewalls and the first lid sidewall; and a second lid defined by a second interior portion and a second exterior portion, the second interior portion having a plurality of second grinding members, the second exterior portion having a second lid end from which extends a second lid sidewall, the second lid sidewall defined by a second lid diameter, the second lid diameter configured to be infinitesimally smaller or larger than the compartment diameter, the second lid disposed to detachably mate with the second compartment end, wherein an airtight seal forms between the compartment sidewalls and the first lid sidewall, the second lid further disposed to detachably mate with the first lid, wherein a compressive and rotational force applied to the first lid and the second lid generates a grinding action between the plurality of first grinding members and the plurality of second grinding members.
