ABSTRACT:
A cigarette holder substantially made of an integrally formed body member which includes an outer hollow cylindrical portion with both of its ends open, the inner space within which is divided into a radially larger bore and a radially smaller bore by a transverse dividing wall portion, from which an inner cylinder portion extends coaxially for a certain distance into the radially smaller bore so as to define a narrow annular space therebetween. An outer peripheral portion of the dividing wall portion is pierced with a groove which extends axially from the radially larger bore side of the dividing wall portion toward the radially smaller bore beyond the thickness of the dividing wall portion, the groove having a radial depth larger than a half of the difference of the diameters of the radially larger and smaller bores, thereby defining a restriction passage which generates a high speed flow of smoke towards the outer peripheral surface of the inner cylindrical member. The radially larger bore is adapted to receive a cigarette.
