A container apparatus includes a container body and a container lid. The container body defines a first internal cavity. The container lid is attached to the container body and defines a second internal cavity. The container lid includes protrusions extending within the second internal cavity to grind solid materials.

The invention involves a grinder safety cap suitable for medicinal items such as herbs or other consumable substances that may be desirably restricted from children, and which may require grinding and/or homogenizing before ingestion. The grinder safety cap is comprised of a cover shell and base shell, wherein the cover shell fits snugly over an upwardly extending top wall of the base shell. The base shell may have upwardly extending grinding protrusions, having sharp and/or serrated edges, capable of grinding, cutting, or otherwise reducing the particle size of a consumable substance. The cover shell may also have downwardly extending grinding protrusions. A consumable substance may be placed within a cavity or receptacle of the base shell, the cover shell may be placed over the top wall of the base shell so as to close the grinder safety cap, and the consumable substance may be ground by turning the cover shell.

An apparatus including a grinder lid section; a grinder section configured to be attached to and detached from the grinder lid section, so that when the grinder section is attached to the grinder lid section the grinder lid section rotates with respect to the grinder section; a funnel section configured to be attached to and detached from the grinder section, so that when the funnel section is attached to the grinder section the funnel section does not rotate with respect to the grinder section; and a storage section configured to be attached and detached from the funnel section, so that when the storage section is attached to the funnel section the storage section does not rotate with respect to the funnel section. Each of the grinder lid section and the grinder section has a plurality of pointed teeth which face towards each other.

A coffee grinder-doser includes a grinder-doser body enclosing a grinding chamber which houses first and second mills configured and mutually positioned to grind coffee beans into powder. An external ring-nut which is gripped and rotated by an operator integrally connects to the first mill. A nut screw with a longitudinal axis, inside the grinding chamber, is engaged with an external thread of the ring-nut to translate the first mill along the longitudinal axis. The ring-nut includes a ring-nut body and indices defining the angular position thereof. The grinder-doser body includes a fixed reference for the indices. The ring-nut is associated with a graduated ring having the indices, and a cover at least partially removable to lock the graduated ring between the cover and the ring-nut. The cover is fixed to the ring-nut body by a partially removable couple for adjusting and locking the angular position of the graduated ring.

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.
