DETAILED DESCRIPTION OF THE INVENTION

[0043] By convention, the axial direction corresponds to the main extension of the receptacle, illustrated by the axis X in FIG. 1, and the radial direction is orthogonal to the axial direction.

[0044] In the following detailed description of the figures, the terms upper and lower or high and low will be used without limitation in reference to the axial direction.

[0045] Similarly, the terms outer or external and inner or internal are used with reference to the radial direction, an outer element being radially further from the axis X than an inner element.

[0046] The pot 1 for dispensing a cosmetic product shown in FIGS. 1 and 2 extends along a main axis X and consists mainly of a base 2 into which a cup 3 is inserted. A lid (not shown) comes to seal the base 2 by screwing or any other conventional attachment method.

[0047] The cup 3 packages the cosmetic product. The cup 3 is a product refill and is removable from the base 2 so that it can be replaced by a new cup 3 filled with product when the previous one is empty.

[0048] By cosmetic product, we mean, for example, a make-up powder, or a semi-fluid product such as a cream or foundation type.

[0049] The base 2 and the cup 3 have forms of revolution about the main axis X. They are hollow and open at the upper portion.

[0050] The cup 3, which can contain the product, is housed inside the base 2.

[0051] The base 2 comprises a bottom.

[0052] However, an embodiment in which the base 2 has no bottom is within the scope of the present invention. In this case, the bottom 10 of the cup 3 will act as the bottom for the pot 1.

[0053] The cup 3, as shown in FIGS. 4 and 5, has a peripheral wall 31 and is open at the upper portion.

[0054] The peripheral wall 31 is surmounted by a flat external shoulder 33 oriented perpendicularly to the axis X. An annular collar 32 oriented parallel to the axis X extends from this external shoulder 33. This collar 32 extends towards the bottom 10 of the cup 3.

[0055] This collar 32 is continuous all around the upper portion of the cup 3. It is located at a distance from the peripheral wall 31 of the cup 3, so as to create a gap 35 between them, the function of which will be explained later in the description.

[0056] This collar 32 has a lower rim 36 with a continuous profile extending around the entire circumference of the collar 32.

[0057] This lower rim 36 comprises ramps 30 for positioning the cup 3 in the base 2.

[0058] Preferably the lower rim 36 comprises two diametrically opposed ramps 30.

[0059] In another example, the collar 32 could comprise more than two ramps 30.

[0060] Switching from one ramp 30 to another is done via a return 39 positioned at the end of one ramp 30 and at the start of the adjacent ramp 30. In this way, each ramp 30 starts after a return 39, and each ramp 30 ends with a return 39. Each return 39 marks a junction between two ramps 30 so as to form the continuous profile of the external shoulder 26.

[0061] The inclination of the ramps 30 is directed towards the bottom 10 of the cup 3, while the inclination of the return 39 is directed towards the external shoulder 33 of the cup 3. The ramp 30 and the return 39 therefore have opposite slopes.

[0062] The collar 32 has gripping lugs 34, i.e. relatively large areas where the user can place his fingers to grip the cup 3.

[0063] Each area must be large enough to accommodate at least one finger. Preferably, the collar 32 comprises two diametrically opposed lugs 34. In this way, the user can hold the cup 3 with two fingers of the same hand.

[0064] In another example, there could be three or four lugs 34. The lugs 34 are delimited mainly on one side by the end of a ramp 30 and its return 34, and on the other side by the edge 11 located between the external shoulder 33 and the collar 32.

[0065] The base 2, as shown in FIG. 3, comprises a reservoir 21 surmounted by a neck 22 having attachment means which can cooperate with a lid. In this case, it is an external thread 25 provided around the neck 22, and which is able to cooperate with an internal thread provided in the lid. More specifically, the neck 22 of the base 2 has a lower annular area 23 for attaching to the lid, as this lower annular area 23 comprises said external thread 25.

[0066] The neck 22 of the base 2 also has an upper annular area 24 designed to receive the collar 32 of the cup 3 when the latter is placed in the base 2.

[0067] This upper annular area 24 is refined, which means that its thickness is thinner than the thickness of the lower annular area 23. This results in the creation of an external shoulder 26.

[0068] This external shoulder 26 has a continuous profile that matches the profile of the lower rim 36 of the collar 32. The shape of the lower rim 36 and the shoulder 26 therefore match, so that the lower rim 36 can rest on the shoulder 26 after the cup 3 has been positioned in the base 2.

[0069] The external shoulder 26 has a plurality of ramps 20 and returns 29, like the lower rim 36. Thus, each ramp 20 ends with a return 29 and starts after a return 29, each return 29 marking a junction between two ramps 20 so as to form the continuous profile of the external shoulder 26. When the user comes to mount the cup 3 in the base 2, he pushes the peripheral wall 31 of the cup 3 into the cavity of the base 2, then the ramp 39 of the lower rim 36 comes into contact with the ramp 29 of the external shoulder 26. To complete the insertion of the cup 3, the user simply turns the cup 3 relative to the base 2 so that the lower rim 36 slides over the shoulder 26 along the ramps 30, 20, until the returns 39 of the lower rim 36 of the cup 3 comes in abutment against the returns 29 of the external shoulder 26 of the base 2. These abutments indicate the end of the mounting of the cup 3 in the base 2. The cup 3 is then placed into the base 2. This insertion and the positioning is made very easy by the clean, continuous lines of the collar 32 of the cup 3 and the neck 22 of the base 2.

[0070] It is understood from this description that the cup 3 is inserted into the base 2 using a single hand, by an axial movement of the cup 3 relative to the base 2, followed by positioning the cup 3 in the base 2 by a rotational movement of the cup 3 relative to the base 2.

[0071] When the cup 3 is positioned in the base 2, the end of the refined upper annular area 24 is housed in the gap 35 of the cup 3 provided between the collar 32 and the peripheral wall 31 of the cup 3. And the collar 32 externally covers the refined upper annular area 24. Preferably, the thickness of the collar 32 compensates the refining of the upper annular area 24 so that the collar 32 is flush with the lower annular area 23. The collar 32 is nested into the upper annular area 24 of the neck 22.

[0072] Advantageously, the pot 1 comprises means for axially blocking the cup 3 in base 2.

[0073] These means for axially blocking the cup 3 consist, for example, of a rib 28 provided on the upper annular area 24 of the base 2, as illustrated in FIG. 3, and able to be positioned axially downstream, i.e. above, another rib 38 provided for this purpose in the internal wall of the collar 32 as shown in FIG. 5, the ribs 28, 38 being oriented radially so as to block any axial movement of the cup 3 with respect to the base 2. In other words, the base 2 carries a high rib 28, and the cup 3 carries a low rib 38, so that the high rib 28 retains the low rib 38 when the user accidentally lifts the cup 3 along the axis X. The high rib 28 acts as an abutment against which the low rib 38 comes to bear when the cup 3 is accidentally moved axially away from the base 2.

[0074] The upper rib 28 acts as a hard point to pass over when the cup 3 is actually removed.

[0075] In the example shown, the rib 28 of the base 2 extends from a return 29 of the external shoulder 26 on the upper refined annular area, and the rib 38 of the cup 3 extends from a return 39 of the lower rim 36, on the reverse side of a gripping lug 34. In this way, the rib 28 is nested into the gap 35 above the rib 38 only when the cup 3 has been mounted in the base 2.

[0076] In another example, the rib 38 could be replaced by a groove into which the rib 28 fits.

[0077] Advantageously, the pot 1 comprises means for blocking the cup 3 against rotation in the base 2.

[0078] These means for blocking the cup 3 against rotation consist, for example, of a notch 27 provided on the external shoulder 26 of the base 2, as shown in FIG. 3, and suitable for receiving a protuberance 37 provided for this purpose on the lower rim 36 of the collar 32 of the cup 3, as shown in FIG. 4. The notch 27 and the protuberance 37 are each provided at the very beginning of the ramp 20, 30, just downstream of a return 29, 39, so that they snap-fit into place only at the end of the mounting of the cup 3 in the base 2. After snap-fitting, the cup 3 is blocked against rotation relative to the base 2, in both directions of rotation, as the protuberance 37 comes into abutment against the lateral walls defining the notch 27. This prevents the cup 3 from rotating in the base 2.

[0079] In another example, the notch 27 could be made on the lower rim 36 of the collar 32 of the cup 3, while the protuberance would be provided on the external shoulder 26 of the base 2.

[0080] Preferably, the base 2 is made of glass, terracotta, concrete, wood or metal for an aesthetic effect, and the cup 3 is made of aluminium or a plastic material.

[0081] The plastic material may be selected from polypropylene (PP), recycled polypropylene (R-PP), polyethylene terephthalate (PET), recycled polyethylene terephthalate (R-PET), thermoplastic elastomer (TPE), polyethylene (PE), such as the low density polyethylene (LDPE) and/or the high density polyethylene (HDPE), composite material, post-consumer recycled material (PCR and/or similar material). Preferably, it is polypropylene and/or polyethylene terephthalate, whether recycled or not. Advantageously, all the parts, i.e. the base 2, the cup 3 and possibly the lid, are made of a plastic chosen from polypropylene and/or polyethylene terephthalate.

[0082] In addition, the use of plastics, in particular similar plastics for the entire pot 1, allow to facilitate the recycling. In particular, the polypropylene and the polyethylene terephthalate are two plastic materials whose recycling cycle is well known.

[0083] The pot 1 can be made in 3D printing.

[0084] In particular, the base 2, the cup 3 and possibly the lid can be produced using 3D printing. Such a printing method allows in particular to freely produce these pieces with patterns and shapes that contribute to the aesthetic appearance of the pot 1.

[0085] The configurations shown in the cited figures are only possible examples, in no way limiting, of the invention which, on the contrary, encompasses the variations of shapes and designs within the reach of the person skilled in the art.
