1. Assembly (1) for packaging and dispensing a cosmetic product comprising:
a reservoir (10) delimiting an internal volume (14) intended to contain the cosmetic product and comprising an opening (16a) for accessing said internal volume (14), the inner surface of said opening comprising at least one shoulder (18c); and
a member (20) for closing the opening (16a) of the reservoir, comprising a mounting skirt (22) extending along an elevation axis (Z-Z′), mounted in the reservoir, and delimited axially by an open lower end (22a) and an upper end (22b) on the opposite side from the lower end (22a), a closure member (20) comprising an annular flange (22c) protruding radially towards the outside from the upper end (22b) of the mounting skirt (22), the annular flange (22c) comprising an outer diameter greater than the diameter of the opening (16a) of the reservoir (10) and bearing axially against the upper end of said reservoir, the closure member (20) further comprising a radial upper wall (24) that closes the upper end (22b) of the mounting skirt (22) and is provided with at least one dispensing orifice (24a) for the cosmetic product contained in the reservoir (10) to pass through, characterized in that said closure member (20) comprises:
a fastening lip (28) delimited axially by a proximal end (28a) connected to the mounting skirt (22) and a free distal end (28b), on the opposite side from the proximal end (28a), the fastening lip (28), in the position fastening the closure member in the opening of the reservoir, being folded and radially surrounding the mounting skirt, the distal end (28b) of said fastening lip (28) butting axially against the shoulder (18c) of the reservoir (10), and in that
in an initial position where the closure member (20) is not mounted in the reservoir (10), the fastening lip (28) protrudes towards the outside with respect to an outer cylindrical surface (22d) of the mounting skirt (22) forming an obtuse angle (a1) with respect to said surface (22d), and the free distal end (28b) of the fastening lip has an outer diameter greater than the inner diameter of the reservoir (10) in order to obtain the turning of the fastening lip (28) into the folded position fastening during the assembly of the closure member (20) in the reservoir (10).
