Abstract
Described herein are containers having a bottom portion, a bottom sifter, a dial sifter, and a removable cover having pins. A bottom sifter and a dial sifter are rotatably engaged, and both have at least one sifting hole for sifting materials with a powder-like consistency. Either the surface of the bottom sifter facing the dial sifter or the surface of the dial sifter facing the bottom sifter may have at least one raised portion, and the remaining surface may have at least one recessed depression. The dial sifter may have one or more cavities to engage the pins in the cover, thereby rotating the dial with the rotation of the cover.
Claims15
An apparatus comprising:
- a bottom portion;
- a bottom sifter engaged with the bottom portion and having at least one sifting hole;
- a dial sifter rotatably engaged with the bottom sifter and having at least one sifting hole and at least one axially extending cavity;
- and
- a removable cover having at least one axially protruding pin to extend into the axially extending cavity in the dial sifter, the at least one axially protruding pin being in a spring-compressed state to facilitate engagement of the cover with the dial sifter and the dial sifter having a channel to guide travel of the at least one pin protruding from the cover along a surface of the dial sifter, wherein the pin is configured to engage with the dial sifter so that:
- when the cover is rotated into a closed position the dial sifter is rotated in relation to the bottom sifter to offset the at least one sifting hole in the bottom sifter and the at least one sifting hole in the dial sifter, and
- when the cover is rotated into an open position the dial sifter is rotated in relation to the bottom sifter to align the at least one sifting hole in the bottom sifter with the at least one sifting hole in the dial sifter.
