Abstract
The cup to be used as a paste carrier for dental hygienic consists of a rubber elastic material and can be driven for rotation by a hand piece. The cup comprises a paste receiving part, the inner side enlarging towards its open edge as well as the outer side of the cup enlarging towards its open edge comprising spiraled ribs which are running in the opposite direction to the rotational direction of the hand piece. The structure on the inner side of the paste receiving part allows a continuous supply of paste and a cooling of the cup, and the structure of the outer side of the cup prevents a bale formation of the mucous and guarantees an effective cooling of the cup.
