ABSTRACT:
A cuspidor or spitting device for dental purposes comprising a bowl formed by a lateral curved wall and a conical bottom surface with the upper edge of the lateral curved wall merging with an inclined surface portion of the upper surface of the housing and the bottom wall having a discharge opening leading to a discharge channel. The lateral wall is preferably a cylinder or a tapering surface substantially forming a cylinder whose axis of rotation is arranged to incline from the user's side and forms an acute angle with the axis of the conical surface forming the bottom wall. Thus, the surfaces are smooth and easily cleaned and do not provide cracks or crevices for accumulation of dirt and prevent anti-hygienic conditions from occurring.
