A mixing container for manufacturing dental preparations has a first part that contains a powdered material and a second separable part, that contains a liquid in a destructible foil bag. The bag is destroyed by a movable pestle. The resistance to ripping of the foil bag and the pressure impulse applied by the pestle when the container is shaken in an oscillating mixer are proportioned to result in the destruction of the bag when struck by the pestle. The pestle has elevations and guides in preferred embodiments.
