Abstract
A receptacle for the weighing-in of free-flowing substances has a fill opening, a tubular-shaped circumference wall, and a bottom part. The bottom part is connected to the tubular-shaped circumference wall, which it tightly closes off in the direction of gravity when the weighing receptacle is in its operating position. The weighing receptacle can be set on the weighing pan of a balance and can be filled like a beaker with free-flowing substances without allowing the latter to escape therefrom. The bottom part can be opened either by an outside force acting on the weighing receptacle and/or through the influence of a solvent acting on the weighing receptacle, forming an outlet orifice in the bottom part. The weighing receptacle, otherwise tightly sealed in the direction of gravity, can be flushed out with a fluid when the outlet orifice is opened.
