Abstract
Powder chamber for an air polishing device, extending from a top end to a bottom end along an axis, said powder chamber including at least two wall sections, where a first wall section forms a first angle with respect to the axis, and where a second wall section forms a second angle with respect to the axis, where the angles are measured in a measuring direction from the axis to the appropriate wall section in such a manner so that the acute angles are obtained, where the measuring direction from the top end to the bottom end is counted positive, and where the measuring direction from the bottom end to the top end is counted negative, where the second wall section is arranged below the first wall section, and where the second angle is smaller than the first angle.
