Abstract
Abstract The deodorizer device consists of a top piece, shaped as an ashtray, and presenting on its lower side, below the ash-carrying bowl, a downwardly directed flange, into which flange there can be fitted a cup-shaped bottom piece inside which there is placed the deodorizer cake. Both the flange of the top piece and the side wall of the bottom piece present apertures that can be brought in or out of register, thus permitting or stopping the deodorizing activity of the gel cake which is at the interior of the cavity defined by the cup-shaped bottom piece fitted inside the flange of the ashtray-shaped top piece.
