A case for a cosmetic product includes a tray intended to receive the cosmetic product, an actuating means allowing for the passage of the tray from a rest position to a position of use, and a cover. The tray includes a notched zone able to cooperate with a toothed wheel of the cover in such a way that the passage of the tray from the rest position to the position of use results in the opening of the cover, and, reciprocally, the passage of the tray from the position of use to the rest position results in the closing of the cover.
