Abstract
A pot for a cosmetic product including a base topped by a substantially cylindrical neck defining an opening, and a lid equipped with a seal having top and bottom surfaces. The neck of the pot has a rim with an inner periphery having a shoulder forming a concave surface. The bottom surface of the seal includes a flexible annular lip that has a convex shape on an outer peripheral wall which, when the lid is tightened on the base, matches the concave surface over at least a portion of the height of the shoulder and presses sealingly against the rim around the entire inner periphery of same to sealingly close the pot. The flexibility of the seal and the shape of the lip thereof, which complements that of the rim, allow it to be deformed to be able to compensate for dimensional irregularities during at manufacture ensuring tight sealing.
