Abstract
A plastic stackable measuring scoop of the type which is frequently included in packages of granular detergents wherein a generally rectilinear scoop bowl has a front wall which slopes inwardly from top to bottom and a rear wall the central portion of which also slopes inwardly from top to bottom and has a corrugation providing a median ridge terminating just above the bottom of the bowl as an inwardly projecting shoulder which serves as a stop to limit the extent of entry of a scoop bowl thereinto. The front wall of the shoulder has a five degree backdraft to increase the distance that the shoulder extends inwardly. The slope of the central portion of the back wall of the bowl is substantially greater than the draft of the side portions thereof.
