A grinding device for containers dispensing food products, which includes means for selectively adjusting the distance between blades and teeth and thereby selecting at will the desired grain size for grinding. The device has a static piece that is coupled to the neck of the container and is connected to a rotary piece such that the fixed piece includes a series of teeth which, together with blades projecting from the bottom face of the rotary piece, constitute the grinding mechanism of the device. The device includes, on the outside of the fixed piece, two or more channels that guide the rotation and axial retention of the rotary piece, while the rotary piece contains projections for fitting into the channels of the fixed piece.

The mill for spice products, in particular such as cinnamon sticks, houses a reservoir for storing the spice product. The reservoir communicates through a passage, with a grinding mechanism. The reservoir includes a mechanism for fragmenting the spice product. The mechanism for fragmenting are defined by a crusher of the spice product.

The device for grinding food grains such as flaxseed, includes a bulb rotatably within a bowl. The bulb and the bowl together delimit a functional area, a lower area of which includes a device for moving the grain to a lower area having teeth to grind the grain. There is a device for maintaining, between the bulb and the bowl, at the level of the functional area, a clearance to allow for the grinding of the grains and to avoid all contact between the bulb and the bowl at the level of the space. The space is formed so as to prevent any grains returning from the lower area to the upper area. The invention further concerns a mill equipped with such a device for grinding food grains.

A coffee bean grinder is provided, comprising a housing assembly, a shaft component, and a securing member. The shaft component is assembled in the housing assembly. When a coffee bean grinding complex is formed by an inner grinding member of the shaft component and an outer grinding member of the housing assembly, the shaft component and the housing assembly can be easily assembled and secured through the structural configuration of the securing member, and also through which, the shaft component and the housing assembly can also be disassembled for cleaning and maintenance after grinding operation.

A grinding kit includes a grinding unit having a body defining an inner cavity, the body having a receiving end a depositing end. The grinding unit includes a plurality of grinding surfaces disposed within the inner cavity of the body and a drive shaft coupled to the one or more grinding surfaces. The grinding kit includes a first handle configured to removably couple to the drive shaft and configured to rotate about a first axis of rotation while coupled to the drive shaft to drive movement of the plurality of grinding surfaces. The grinding kit includes a second handle configured to removably couple to the drive shaft and configured to rotate about a second axis of rotation while coupled to the drive shaft to drive movement of the plurality of driving surfaces, the second axis of rotation being different from the first axis of rotation

A container when assembled includes a body, a cover, a lower grinding component, and an upper grinding component. The body includes a primary storage area compartment, the lower grinding component includes a grinding area compartment, and the upper grinding component includes a secondary storage area compartment. The upper grinding component partially nests within the lower grinding component. The lower grinding component defines a recess comprising the grinding area compartment. The upper grinding component is inserted into and partially received within the recess of the lower grinding component to form a grinder. The lower grinding component partially nests within the body of the container and the cover fits over the upper grinding component and partially over the lower grinding component when the cover is secured to the body of the grinder, whereby the grinder is completely enclosed within the body and cover of the container.

A coffee grinder has a housing that includes a ring burr, a shaft extending through the ring burr, a frustoconical burr, and an interlocking plug. An internal bore of the frustoconical burr has an upper cylindrical surface adjacent the top end, an interlocking portion adjacent the bottom edge, and a tapered side surface. The interlocking plug is shaped to extend through the internal bore of the frustoconical burr, and includes an upper cylindrical portion that fits through the upper cylindrical surface, and a lower portion that includes a sidewall surface to which is also tapered such that the sidewall surface interlocks with the side surface of the frustoconical burr.
