Abstract: A foodstuff crusher/blender has a hollow body defining a closed elongate cavity. An access device, such as complementary screwthreads on respective ends of two portions of the body, enables the introduction and removal of foodstuff into and from the cavity. A crushing/blending ball is accommodated in the cavity. The cavity is of circular shape along its length in transverse cross-section. One end of the cavity is of substantially part-spherical shape with a diameter not substantially greater than that of the ball. The other end of the cavity is of substantially part-spherical shape with a diameter substantially greater than that of the ball. The diameter of the cavity increases progressively over at least a part of the distance between the two ends of the cavity.

Abstract: A foodstuff crusher/blender comprises a hollow body defining a closed elongate cavity, an access device, such as complementary screwthreads on respective ends of two portions of the body, enabling the introduction and removal of foodstuff into and from the cavity and a crushing/blending ball for accommodation in the cavity. The cavity is of circular shape along its length in transverse cross-section. One end of the cavity is of substantially part-spherical shape with a diameter not substantially greater than that of the ball whilst the other end of the cavity is of substantially part-spherical shape with a diameter substantially greater than that of the ball.
