Abstract
An apparatus for removing powder or lump materials from a storage vessel, obtaining a preselected volume of the material, returning any excess material to the storage vessel, and dispensing the obtained measured material. The apparatus contains a product-receiving part, a handle portion, and a transition area in the shape of a taper which tapers downwardly toward the handle, which transition area connects the product-receiving part with the handle. The handle comprises a tube which is closed by a movable piston. The tube may be marked to facilitate measuring the volume of the material.
