An integral nail polish stirring system includes an integral nail polish stirring cap that with a cap button that when pressed causes a stirring shaft to rotate within the nail polish to stir the nail polish. The cap button has a helical drive shaft extending down into a cap cavity and through a drive platform aperture in a rotating drive platform that rotates the rotating drive platform when the cap button is pressed. The stirring shaft extends from the rotating drive platform opposite the cap button. A spring in the actuation chamber between the cap button and the rotating drive platform returns the cap button to a ready position. The stirring shaft may have a mixing paddle, or an applicator configured thereon. The an integral nail polish stirring cap may be interchanged between nail polish containers.

A convenient-to-stir cosmetic container includes a lid assembly, a bottle assembly, an applicator assembly, and a stirrer, where the applicator assembly is provided in the lid assembly; the lid assembly can cover the bottle assembly; the bottle assembly is provided therein with an accommodation cavity for storing a cosmetic material; the stirrer is provided in the accommodation cavity; the stirrer can move along an axial direction of the bottle assembly, so as to stir the cosmetic material in the accommodation cavity; and a distance between an outer peripheral wall of the stirrer and an inner peripheral wall of the bottle assembly is L1, and the accommodation cavity has a width of L2, L10.1*L2. In the container, the stirrer has a large size, and the stirrer can move along an axial direction of the container.
