A device for packaging and applying a substance may include a receptacle for containing the substance and an applicator. The receptacle may include a first part and a second part, with the second part being turnable by a user relative to the first part. The second part may define at least one surface in contact with the substance inside the receptacle. The applicator and the surface may be arranged in such a manner that turning the surface exerts pressure on the substance, causing the substance to move toward the applicator. The first part may define a backing surface and the surface may be arranged to come at least in part to face the backing surface at an end of turning of the second part.
