  • Publication number: 20080178903
    Abstract: Containers are disclosed for holding and dispensing cosmetic products. Exemplary containers have a bottom portion, a first and second sifter, and a removable cover having a protrusion. The first sifter may have at least one sifting hole for sifting materials with a powder-like consistency. The second sifter may be rotatably engaged with the first sifter and may also have at least one sifting hole. The second sifter may rotate with the rotation of the cover, such that when the cover is rotated into a closed position the second sifter is rotated in relation to the first sifter to offset the holes in the first sifter and the holes in the second sifter. When the cover is rotated into an open position the second sifter is rotated in relation to the first sifter to align the holes in the first sifter with the holes in the second sifter.
