DETAILED DESCRIPTION OF THE INVENTION

[0028] In reference to the figures, the present invention relates to a milling device 1 for a seasoning product traditionally including an annular bowl 2 and a frustoconical bulb 3 whereof the apex 31 is extended by an axial rod 4.

[0029] A flange 6 makes it possible to secure the assembly formed by the bowl 2, the bulb 3 connected to the axial rod 4 at the body 11 of a mill 10, using screws 8. Indeed, the flange 6 is in the shape of a U including two lateral branches 62, 63 connected by a transverse branch 60. The distance d comprised between the two lateral branches 62, 63 is adjusted to the diameter of the bowl 2.

[0030] Thus, in the assembled position of the milling device 1 on the mill 10, the transverse branch 60 of the flange 6 is bearing against the lower edge 23 of the bowl 2 and its lateral branches 62, 63 are bearing against the outer face of the bowl 2.

[0031] The screws 8 for fastening the flange 6 to the body 11 of the mill 10 are traditionally inserted into through passages 65 formed in each of the lateral branches 62, 63 of the flange 6, then screwed in a flange inwardly included by the body 11 of said mill 10.

[0032] Indeed, the latter is hollow and arranges a reservoir 9 for a seasoning product communicating with the bowl 2 when the milling device 1 is assembled on the mill 10.

[0033] Furthermore, the milling device 1 according to the invention includes means for locking the rotation of the bowl 2 relative to the flange 6. In the illustrated alternative embodiment, they are defined by a pair of notches 24 formed in a diametrically opposite manner on the lower edge 23 of the bowl 2 and a pair of stops 64 with a shape complementary to that of the notches 24 included by the flange 6 and each extending at an angle formed between its transverse branch 60 and one of its lateral branches 62, 63. The curved shape of the stops 64 and the notches 24 in the illustrated example further makes it possible to facilitate the proper positioning of the flange 6 relative to the bowl 2.

[0034] The mill 10 also includes a cap 12, topping the body 11 and mounted rotatably on the latter. The cap 12 has an inner through passage centered on the axis of the mill 10, intended to be traversed by the axial rod 4.

[0035] The latter has a threaded free end 40 on which, when it emerges from said passage 13, an adjusting button 14 is traditionally screwed more or less tightly.

[0036] According to one possible alternative embodiment, the bowl 2 and the bulb 3 can be manufactured from ceramic, this material having the advantage of being particularly solid and withstanding permanent contact with a food product that may prove to be corrosive, in particular such as salt. The axial rod 4 and the flange 6 are subject to fewer stresses than the bowl 2 and the bulb 3. As a result, they may advantageously be made from a plastic material, which makes it possible to limit the production cost of the device 1, and consequently of a mill 10. Of course, any other material having equivalent properties may also be considered.

[0037] In the illustrated alternative embodiment, the mill 10 also includes a tube 41 able to be engaged on the axial rod 4 and provided with a plurality of blades 42 distributed on its outer wall and allowing the mixing and driving of the seasoning product toward the bowl 2. This tube 41 is mounted locked in rotation relative to the axial rod 4 and to that end has a square inner section at its lower end 43, able to cooperate with a portion 44 having a complementary square section included by the axial rod 4. The tube 41 is also mounted locked in rotation relative to the cap 12 of the mill 10 and to that end includes a square outer section at its upper end 46 able to cooperate with a portion having a complementary square inner section included by the through passage 13 of the cap 12.

[0038] Owing to such a mill structure 10, the actuation by a user of its cap 12 results in rotating the axial rod 4 and therefore the bulb 3 relative to the bowl 2.

[0039] This rotational movement makes it possible to orient the seasoning product, falling by gravity from the reservoir 9 formed by the body 11 of the mill 10 toward the bowl 2, toward the teeth 32, 20 respectively included by the outer face of the bulb 3 and the inner face of the bowl 2. The seasoning product is milled by friction on the teeth 32, 20 and ultimately discharged outside the mill 10 in the form of a more or less fine powder.

[0040] According to the invention, the milling device 1 further includes a centering disk 5 with a diameter identical to that of the bowl 2, including a central orifice 50 allowing the passage of the axial rod 4, said orifice 50 having a circular section complementary to the base 45 of the axial rod 4.

[0041] The centering disk 5 also has two half-moon-shaped lumens 51, symmetrical relative to its axis, and allowing the passage of the seasoning product contained in the reservoir 9 of the mill 10 and therefore its introduction into the bowl 2.

[0042] The centering disk 5 is mounted locked in rotation relative to the bowl 2 and to that end includes a pair of tabs 52 extending diametrically opposite one another on its edge in the extension of its lower face 53 and intended to be housed in a pair of notches 21 made in a diametrically opposite manner on the upper edge 22 of the bowl 2 and having a shape complementary to that of said tabs 52.

[0043] The presence of the centering disk 5 makes it possible to align the axial rod 4 and therefore the bulb 3 with the axis X of the bowl 2. The centering disk 5 thus makes it possible to lock the apex 31 of the bulb 3 in position and to prevent any untimely translational movement of the axial rod 4 along an axis perpendicular to the axis X of the bowl 2.

[0044] In the illustrated alternative embodiment, the flange 6 also includes a cylindrical stud 7 centered on the upper face 61 of its transverse branch 60, while the lower face 30 of the bulb 3 includes an indentation 33 complementary to the cylindrical stud 7 and with an axis aligned with that of the axial rod 4. This feature also makes it possible to lock the bulb 3 in position and to guarantee the alignment of its axis with that of the bowl 2 over its entire height.

[0045] It clearly emerges from the foregoing that the milling device 1 according to the invention includes technical means making it possible to achieve the goal set out in the preamble, which is to guarantee centering of the bulb 3 relative to the bowl 2 at any time during the actuation of the mill 10. Owing to such a feature, the longevity and reliability of the milling device 1 according to the invention are improved, as well as the quality of the collected food product powder.

[0046] It should be noted that the milling device 1 according to the invention is designed as a universal module suitable for adapting to a large number of mills having different shapes and characteristics.

[0047] Of course, many changes can be made to the examples described above without going beyond the scope of the present invention.
