Abstract
A sifter cap for continuous thread containers of the type adapted to dispense a granular product. There is provided a screw cap adapted for securement to the container, and a sifter member disposed atop the screw cap and adapted for rotation with respect thereto. The screw cap has an annular, upwardly-facing bearing shoulder, and the sifter member has at least three downwardly-faced bearing nibs which slidably engage the bearing shoulder of the screw cap at relatively small areas of contact. The arrangement is such that the the sliding engagement between the screw cap and sifter member is characterized by reduced friction. In addition, in the event that granular product from the container strays onto the bearing shoulder of the screw cap, little resistance against rotation is encountered. As a consequence, there is thus enabled relatively smooth turning of the sifter member on the screw cap.
