1. A packaging device for a cosmetic product, comprising:
a cosmetic product reservoir, comprising an internal volume and an opening providing access to said internal volume;
a seal, mounted fixed on an edge of the opening; and
a cover, that can be removably assembled to the reservoir in a closed position;
said cover comprising a closing element capable of cooperating with the seal so as to close and seal the opening in the closed position;
the device wherein:
the seal comprises a tubular shaped skirt for receiving the closing element, said skirt being arranged along an axis passing through the opening of the reservoir and comprising a free edge oriented towards the exterior of said reservoir, the free edge being elastically deformable in the radial direction relative to said axis;
wherein the closing element is configured to radially deform said free edge in the closed position; and the packaging device is configured such that a free angular space is formed around the skirt in the closed position, so as to enable the free edge to radially stretch during insertion of the closing element in the skirt to the closed position, for ensuring a sealed closure of the cosmetic product reservoir;
wherein an internal face of the skirt comprises an annular bead arranged close to the free edge, said annular bead being configured, when in the closed position, to come into contact with and be elastically deformed in the radial direction by the closing element.
