Device for measuring powdered product from a can container comprises a plurality tier of trays or rings rotatably stacked one upon the other and characterized in that, each tray carries a half circle storage excavation, the rest portion remaining solid, the top ring having a cylindrical outlet communicable to the hollow storage space while the bottom ring has tapered guide surface leading from the solid portion toward the hollow portion, and being adapted to the open end of the can container. Under the center of the topmost tray or ring, a shaft is stemmed to pass through the center opening provided in the intermediate trays and circular concave-convex meshable tongue-grooves are provided between adjacent surfaces to facilitate relative rotations. When the device is assembled have the hollow space aligned on top of the opened can, the whole thing is turned upside down, the powdered content in the hollow space is intersected by turning an appropriate intermediate ring, a required amount of the content is clearly cut out and poured out from the outlet without contamination.
