Abstract
A sifting apparatus and container for storing and dispensing material, such as cosmetic powder are described. Two sifters are arranged so their holes are not aligned, and a resilient material is placed between the sifters to create a gap that allows powder to pass out from a storage cavity to a surface accessible by the user. In a second configuration, at least one of the sifters is displaced toward the other sifter to reduce or eliminate the gap, thus reducing or preventing the flow of material through the sifters.
Claims24
A container comprising:
- a cover, and,
- a bottom portion including:
- a base,
- a first sifter engaged with the base,
- a second sifter engaged with first sifter such that a gap is present between at least a portion of the first sifter and at least a portion of the second sifter to permit material to pass through the first sifter, the second sifters, and the gap;
- and
- a gasket adapted to maintain the gap between the portions of the first and second sifters when the cover is not engaged with the bottom portion,
- wherein the cover is adapted to engage the bottom portion displacing the second sifter toward the first sifter to prevent material from passing through the first sifter, the second sifter, and the gap.
A container according to 9, wherein the pitch of the threads between the first and second sifter differs from the pitch of the threads securing the cap.
An apparatus comprising:
- a base holding material to be dispensed;
- a first sifter having a sifting hole, the first sifter being engaged to the base;
- a second sifter having a sifting hole, the second sifter engaged to the first sifter;
- a gasket;
- and
- a displacement mechanism to displace the second sifter toward the first sifter to prevent the flow of the material to the exterior surface of the second sifter when the displacement mechanism is placed into an engaged position, wherein the gasket maintains a gap between the first sifter and the second sifter when the displacement mechanism is placed into a disengaged position to allow material to flow through the sifting hole in the first sifter, the sifting hole in the second sifter, and the gap.
A sifting apparatus comprising:
- a first sifter,
- a second sifter engaged with the first sifter such that a gap is present between a portion of the first sifter and a portion of the second sifter to permit material to pass through the first sifter, the second sifter, and the gap;
- a displacement mechanism operable to displace the second sifter toward the first sifter to prevent the flow of the material through the first sifter, the second sifter, and the gap, and,
- a gasket adapted to maintain the gap between the portions of the first and second sifters.
