A pocket sized weed grinder is provided herein. The weed grinder includes a single board, including at least four panels, at least one folding line disposed between adjacent panels of the at least four panels, for forming a closed flat cell between two of the adjacent panels, and two grinding plates, each grinding plate disposed on each of two of the adjacent panels. At least one of the two grinding plates is movable in linear motion with respect to the other. The weed grinder enables grinding of weed, accumulating the ground weed within the weed grinder and pouring the ground weed to a smoking paper, while avoiding the need of a mediator element to which ground weed is poured and from which ground weed is poured into a smoking paper, as in currently used weed grinders.

The present disclosure provides systems and methods for grinding and storing, for example, herbs or spices. In particular, the grinding device of the present disclosure is preferably integrated directly with a mason jar. The grinder can generally include a bottom portion configured to be inserted into the threaded mouth of the mason jar and captured thereto with a common mason jar screw ring. The bottom portion can include a bowl with a plurality of teeth extending upward therefrom. The grinding device can additionally include a top portion with an annular wall extending from a disc portion and teeth extending from the bottom surface of the disc. The top portion can be sized and dimensioned to be received in and engage the bowl of the bottom portion. The user may twist the top portion freely in the bottom portion in order to grind materials therein.

A portable manual grinder has a driving section, a grinding section and a discharging section coaxially connected from top to bottom. The driving section has a drive shaft that drives a central axis of the grinding section. The drive shaft is connected to a gear set that increases the gear ratio to facilitate manual grinding. The grinding section comprises an upper grinding section and a lower grinding section that are coaxially disposed and mated together. The upper and lower grinding portions include corresponding blades extending therefrom. The bottom section of the lower grinding section has one or more holes in communication with the discharge section. The driving section and the upper grinding section are magnetically attracted and connected to each other and the upper grinding section and the lower grinding section are magnetically attracted and connected to each other.

A rotational seasoning dispenser with a dispensing mechanism that applies a rotating disk which has equally separated cavities. When each cavity is in the container the stored seasoning drops into and loads the cavity. Next, the disk transfers and dispenses the seasoning outside by turning the loaded cavities from the container to a dispensing aperture. The disk has smooth, parallel and planar upper and lower planes which slide closely fitting container's planar planes above and below it. This configuration hermetically isolates the container from the environment by providing simultaneous airtight covering of each cavity while it approaches and overlaps the dispensing aperture. This isolation prevents atmospheric moisture absorption which results in lumping of seasoning. The rotating cavities also can loosen lumped seasoning into particulates. An electrically motorized version of the dispenser is also included. The dispenser is configured to dispense substantially equal amounts of seasoning for each manual activation.

A grinder includes a hopper having a top and a bottom and a shaft disposed within the hopper and configured to rotate about a shaft longitudinal axis with respect to the hopper. The shaft includes both a first end nearer to a top of the hopper as compared to a bottom of the hopper and a second end nearer to the bottom of the hopper as compared to the top of the hopper. A blade extends a radial distance outward from the shaft a smaller radial distance at a location on the shaft nearer to the first end of the shaft as compared to a second location on the shaft nearer to the second end.
