Abstract

A measuring vessel for measuring finely-ground packable and dry material, such as ground brewing coffee, cocoa, flour and so on is provided which includes a measuring tube (1) which is open at both ends. The bottom end of the tube includes a constriction (3) with an opening which is defined by an edge (4) which slopes relative to the horizontal plane. The measuring vessel is inserted vertically into the finely-ground material and the material enters the vessel from beneath, through the bottom opening. When the vessel is lifted, the material collected in the vessel will remain therein by virtue of frictional bounds in the material, until the vessel is turned upside down, whereupon the material will run out through the top opening.
