The sifter of the present disclosure uses a pull cord in communication to assist with the sifting of a powdered substance (e.g., flour, sugar). A user places the substance to be sifted into the open end of a top container and actuates the pull cord, which in turn rotates a blade to agitate the powder and help it pass through a screen into a lower container. This design allows a user to keep their hands from touching the powdered product, and for simple cleanup.

1. A sifter, comprising: an upper container;a lower container; anda collar between said upper container and said lower container and connected to each, of said upper container and said lower container, so that said upper container, said collar, and said lower container are stacked in vertical alignment and have a vertical axis therethrough;wherein said collar further comprises a mesh screen, a spring, a cord, and a blade, connected to one another along said vertical axis, andwherein said cord, said spring, and said blade are operably connected to one another, so that actuation of said cord causes said blade to rotate about said vertical axis, to assist in the passage of powder from said upper container, through said mesh screen, and into said lower container. 2. The sifter of claim 1, wherein said collar further comprises a hub, wherein said cord is connected to said hub, said hub is connected to said spring, and said spring is connected to said blade, along said vertical axis, so that actuation of said cord causes said hub to rotate and wind said spring, which in turn causes said blade to rotate. 3. The sifter of claim 2, further comprising a support for holding said spring, wherein said support is connected to said blade, said spring, and said hub along said vertical axis. 4. The sifter of claim 1, wherein said spring is a spiral torsion spring. 5. The sifter of claim 1, wherein said blade comprises a plurality of radial spokes. 6. The sifter of claim 1, wherein said hub comprises a central axle along said vertical axis, and said cord is wound around said central axle. 7. The sifter of claim 1, wherein said collar comprises a cover connected to said upper container, and a base connected to said lower container, and wherein said mesh screen, said spring, said cord, and said blade are disposed between said cover and said base. 8. A sifter, comprising: a container;a collar connected to said container at a bottom end thereof, so that said container and said collar are stacked in vertical alignment and have a vertical axis therethrough;wherein said collar further comprises a mesh screen, a spring, a cord, and a blade connected to one another along said vertical axis, andwherein said cord, said spring, and said blade are operably connected to one another, so that actuation of said cord causes said blade to rotate about said vertical axis, to assist in the passage of powder from said upper container, through said mesh screen. 9. The sifter of claim 8, further comprising a second, bottom container connected to said collar.
