The present invention relates to a device for packaging a cosmetic article (29, 42), comprising: a base (12) defining a storage compartment for receiving a cosmetic article (29); a plate (16) that is rotatable on the base; a lid (14) that is rotatable on the base; The axis of the plate forms an angle less than or equal to 90° with the axis of the lid. A housing provided in the plate (16) comprises a bottom (38) and an elastically deformable side wall (56). In a contact configuration, one edge (54) of the plate is in contact with the inner surface (60) of the lid. Moving said lid toward the closed position slides the plate toward a closed configuration. The bottom (38) of the housing is in contact with the base in the contact configuration. Moving the plate to the closed configuration moves said bottom closer to the axis of the plate.
