a lower rim with a continuous profile extending around an entire circumference of the collar and comprising at least two diametrically opposed ramps, and
at least two diametrically opposed gripping lugs defined in part by the ramps,
wherein the pot further comprises axial-blocking features provided on the cup and on the base and configured to block axially the cup in the base, the axial-blocking feature of the cup being arranged on the gripping lugs,
wherein the pot further comprises rotation-blocking features provided on the cup and on the base and configured to block rotation of the cup in the base, the rotation-blocking feature of the cup being arranged at a distance from the gripping lugs, the rotation-blocking features consisting of complementary interlocking elements respectively provided on the collar of the cup and on an exterior peripheral surface of the neck of the base,
wherein the ramps, the axial-blocking features, and the rotation-blocking features are configured such that a single helical rotational movement of the cup relative to the base simultaneously engages both the axial-blocking features and the rotation-blocking features to secure the cup in the base.
2 . The cup according to claim 1 , wherein each ramp of the lower rim ends in a return, and each ramp starts after a return, each return marking a junction between two ramps so as to form the continuous profile.
3 . The cup according to claim 1 , wherein each gripping lug extends over an angular sector corresponding to at least one eighth of the circumference of the collar.
4 . The pot according to claim 1 , wherein the neck of the base has a refined upper annular area receiving the collar and a lower annular area for attaching to the lid, said lower annular area being delimited from the upper annular area by an external shoulder of continuous profile matching a profile of the lower rim of the collar, the lower rim coming to rest on the external shoulder after the cup has been positioned in the base.
5 . The pot according to claim 4 , wherein the collar externally covers said upper annular area.
6 . The pot according to claim 5 , wherein the external surface of the collar is flush with the external surface the lower annular area.
7 . The pot according to claim 4 , wherein each ramp of the lower rim cooperates with a ramp of the external shoulder, so that the lower rim slides over the external shoulder via these ramps when the cup is mounted in the base.
8 . The pot according to claim 7 , wherein each ramp of the external shoulder terminates in a return, and each ramp starts after a return, each return marking a junction between two ramps so as to form the continuous profile of the external shoulder.
9 . The pot according to claim 4 , wherein the complementary interlocking element of the base is disposed in proximity to an external shoulder of the neck.
10 . The pot according to claim 1 , wherein said axial-blocking features consist of a rib provided on an upper annular area of the base, and capable of being positioned axially downstream of another rib provided for this purpose in an internal wall of the collar, the ribs being oriented radially so as to block any axial displacement of the cup with respect to the base.
11 . The pot according to claim 1 , wherein said rotation-blocking features consist of a notch provided on an external shoulder of the base, the notch being outward facing relative the ramps, and capable of receiving a protuberance provided for this purpose on the lower rim of the collar of the cup, their snap-fitting taking place when the cup has been mounted in the base.
12 . The pot according to claim 11 , wherein each ramp of the lower rim terminates in a return coming in abutment against a return of the external shoulder, indicating an end of mounting of the cup in the base.
13 . The pot according to claim 1 , wherein the base and the cup are made of plastic.
14 . A pot for dispensing a cosmetic product suitable for receiving a cup containing a cosmetic product, the pot having a central axis X and comprising a base comprising a reservoir surmounted by a neck, the reservoir defining a cavity suitable for receiving the cup and being open at the top and suitable for being closed by a lid, the neck of the base having a lower annular zone for attachment to the lid and an upper annular zone for attachment to the cup, wherein the neck comprises axial-blocking features for axially locking the cup in the base and rotation-blocking features for rotationally locking the cup in the base, said axial-blocking features being independent of said rotation-blocking features, and wherein the upper annular zone comprises ramps configured to cooperate with corresponding ramps on the cup such that a single helical rotational movement of the cup relative to the base simultaneously engages both the axial-blocking features and the rotation-blocking features to secure the cup in the base, wherein the rotation-blocking features consist of complementary interlocking elements respectively provided on the collar of the cup and on an exterior peripheral surface of the neck of the base.
15 . The pot according to claim 14 , wherein said axial-blocking features consist of a rib provided on the upper annular zone of the base, said rib being radially oriented.
16 . The pot according to claim 15 , wherein the upper annular zone of the neck is refined, said lower annular zone being delimited from the upper annular zone by an external shoulder of continuous profile on which a collar of the cup is able to come to rest after the cup has been positioned in the base.
17 . The pot according to claim 16 , wherein said complementary interlocking element of the base for locking rotation of the cup comprises partly of a notch provided on the external shoulder of the base, the notch being outward facing relative the ramps.
18 . The pot according to claim 17 , wherein the notch is capable of receiving a protuberance provided for this purpose on the lower rim of the collar of the cup and corresponding to the complementary interlocking element of the cup.
19 . The pot according to claim 16 , wherein the external shoulder has a plurality of ramps and returns, each ramp terminates in a return, and each ramp starts after a return, each return marking a junction between two ramps so as to form the continuous profile of the external shoulder.
20 . The pot according to claim 19 , wherein a notch is provided at the start of a ramp just downstream of a return.
