Abstract: The packaging includes a container provided with an opening at the top and bounding a housing designed to receive the product, a lid designed to close the opening of the container and a deformable membrane borne by the lid to ensure the leak-tightness of the housing when the lid is in a closed position. The deformable membrane includes a generally flexible central wall surrounded by a generally rigid annular rim which is urged in the axial direction of closure by spring element bearing on a base of the lid such that the annular rim bears in a leak-tight manner on an annular bearing surrounding the opening of the container when the lid is in the closed position and the central wall may be deformed as a result of the differences in pressure prevailing on either side of the deformable membrane. The packaging may be used in particular for cosmetic preparations.

Abstract: The invention relates to a stopping capsule with self-retracting spout which comprises a capsule body with a central orifice, a mobile spout and a rotating lid which controls the emergence and retraction of the spout. The capsule body comprises a shaft which communicates with the spout by a supple, elastically deformable, hollow body, and the lid comprises a sleeve fitted in the shaft and presenting a lateral hole capable of being opposite the pipe of the spout.
