A sifter insert for the neck of a powder jar is secured above the product reservoir and below the cap of the jar. The insert has a central concave dish for supporting a quantity of powder product, and a channel around the perimeter of the dish. The insert is secured in the neck such that the dish is spaced below the bottom of the cap. Slots in the channel permit the flow of powder from the reservoir into the channel when the jar is inverted with the cap closed, and from the channel onto the dish when the inverted jar is righted. Powder in the dish is accessed by the user upon removal of the cap. The cap is then closed and the jar shaken to return excess powder from the dish to the reservoir through the slots in the channel. |
