DETAILED DESCRIPTION OF THE INVENTION

(10) According to the figures, in the illustrated embodiment variant, the spice mill 1 according to the invention includes a body 2 housing a reservoir 3 for storing a spice product communicating, through a passage 5, with a grinding mechanism 4. The latter conventionally includes a toothed bulb 40, rotatable in a toothed cup 41 through a rod 42 suitable for being actuated by a user manipulating the mill 1.

(11) It is specified that the different component parts of the mill 1 are manufactured from materials conventionally used for that purpose, suitable for the food field, such as plastic, wood, ceramic, metal, or any other material having equivalent properties.

(12) In reference to FIGS. 2 and 4, in the illustrated embodiment variant, the reservoir 3 is defined by a hollow cylinder 6A, having a length (reservoir height L) in the order of 15 cm and an inner cylinder diameter d in the order of 4 cm. The reservoir 3 is closed by an arch (top arched surface 8) and a bottom (bottom arched surface 9) and is provided with a plurality of inlet orifices 90 (cf. FIG. 7) in the bottom arched surface toward the passage 5, specifically molded so as only to allow fragments to pass whose size is adapted to the grinding means or mechanism 4 with which the mill 1 is equipped, the others remaining retained in the reservoir 3 until they have the required size.

(13) More specifically, the reservoir 3 is made up of a first part, called “upper part” 6, and a second part, called “lower part” 7, which are separable, respectively including the arch 8 and the bottom 9 (the top ached surface 8 being in the upper part 6, the bottom arched surface 9 being in the lower part 7). The lower end 60 of the upper part 6 and the upper end 70 of the lower part 7 have a complementary structure, so as to allow nesting thereof. Furthermore, the presence of a thread on each of the ends 60, 70 makes it possible to ensure, in their nested state, the blocking in position of the upper 6 and lower 7 parts relative to one another. Providing such a two-part structure of the reservoir 3 makes it possible, after separation of the upper part 6 from the lower part 7, to offer access to the inner volume 10 of the reservoir 3, in particular in order to arrange the spice product to be ground therein.

(14) It should be noted that in the illustrated embodiment variant, the lower part 7 and the body 2 of the mill 1 are rotated relative to one another, the bulb 40 of the grinding mechanism 4 being secured to the lower part 7, while the cup 41 is secured to the body 2.

(15) According to the invention, a ball 11, for example made from metal, the mass m of which is in the order of 65 g, and the diameter D of which is in the order of 2 cm, is positioned freely in the inner volume 10 of the reservoir 3, in which it is therefore able to move in all directions under the action of shaking of the mill 1 by a user. Indeed, the ball 11, projected on a spice product contained in the reservoir 3, makes it possible to mix the latter and to reduce it to small and homogeneous fragments, able to pass through the orifices 90 and to be gradually introduced into the passage 5 to feed the grinding mechanism 4 with particles that the latter is able to transform into quality powder.

(16) According to the invention, the dimensions of the reservoir 3 and the ball 11, as well as the mass thereof, are specifically calculated to allow effective fractionation of all spice products that are dry and hard in raw state, irrespective of their shape, size or density. Thus, the mill 1 according to the invention has a certain versatility and is suitable for reducing to powder with a high gustatory quality, adequate particle size and pleasant texture, all spices or herbs having a dry and hard nature, that is to say both cinnamon and star anise, as well as long pepper or cloves, etc.

(17) Furthermore, it should be noted that in the considered embodiment variant, the reservoir 3 has a diameter d equal to two times the diameter D of the ball 11. Such a feature advantageously makes it possible to prevent the spice product from remaining jammed in the reservoir 3, between the inner face thereof and the ball 11, and to guarantee that it continuously feeds the grinding mechanism, once reduced into small fragments able to enter the passage 5.

(18) Furthermore, as illustrated in the figures, the inner face of the reservoir 3 includes a plurality of ribs 12, 13 respectively distributed, radially, on its arch 8 and its bottom 9 (top arched surface 8 has an inner arched top face 8A with inner arched top ribs 12, the bottom arched surface 9 has an inner arched bottom face 9A with inner arched bottom ribs 13). Adjacent inner arched bottom ribs 13 can be placed around each of the various inlet orifices 90 toward the passage 5. In short, these ribs define a plurality of protuberances pointing toward the inner volume 10 of the reservoir 3 and on which the ball 11 and the spice product undergo additional impacts, thus improving the fragmentation and the mixing of said product.

(19) In order to guarantee the solidity and the robustness of the mill 1, damping means are provided, defined by two rings 14, 15 made from an elastomeric material arranged, for one, between the reservoir 3 and the grinding mechanism 4, and for the other, between the upper 6 and lower 7 parts of the reservoir 3. These rings 14, 15 make it possible to absorb the impacts due to the successive movements of the ball 11 in the reservoir 3 and to preserve the integrity of the component elements of the mill 1 and therefore the safety of the user.

(20) In the illustrated embodiment variant, the grinding means 4 (toothed bulb 40, toothed cup 41, and rod 42) also advantageously includes means for mixing (toothed bulb surface 40A and toothed cup 41A surface) the fragments of spice product introduced into the passage 5 making it possible to prevent pieces from stagnating therein.

(21) Means for adjusting 16 fineness of the grinding, making it possible to adjust the distance extending between the outer wall of the bulb 40 and the inner wall of the cup 41 are also provided in the embodiment variant illustrated in the cam 16A attached to the rod 42 in FIG. 8.

(22) In practice, during the use of the mill 1 according to the invention, the user first introduces the spice product to be ground into the reservoir 3 by accessing its inner volume 10 following a separation of the upper 6 and lower 7 parts. Once the latter are reassembled, it suffices first for the user to shake the mill 1 at a substantially constant speed in order for the spice product to be fragmented into several small parts able to pass through the orifices 90 at the bottom of the reservoir and to enter the space extending between the bulb 40 and the cup 41. A rotational movement applied for example to the body 2 of the mill 1 relative to the lower part 7 of the reservoir 3 makes it possible to cause the rotation of the cup 41 relative to the bulb 40, and therefore to grind the spice product previously fragmented into fine powder.
