Disposable cigarette-end receptacle

Abstract

Disposable cigarette-end receptacle that comprises an inlet orifice having a conical mouth towards the outside. The inside diameter of this orifice is calibrated so as to grip a first cigarette end when it is introduced, to hold it in place and to prevent its withdrawal, this cigarette end thus serving as a plug for the receptacle. This orifice is connected to a receptacle, the only exit of which is the inlet orifice. This receptacle extends substantially along the axis of the inlet orifice, the minimum length of this closed receptacle, along this axis, corresponding to that of a standard cigarette.

1 . Disposable cigarette-end receptacle, characterised in that said disposable cigarette-end receptacle comprises
 a cylindrical inlet orifice with a diameter equal to or less than that of a standard cigarette, having a conical mouth defining an axis, the broad part of which is turned towards the outside, the inside diameter of the orifice, with an axial length less than the diameter of a standard cigarette, being calibrated so as to grip a first cigarette end when the first cigarette is introduced, to hold the first cigarette in place and to prevent withdrawal of the first cigarette, the cigarette end when in the inlet orifice serving as a plug for the receptacle, the retention force for the cigarette end being sufficiently small so that thrust exerted by a second cigarette end forces the first cigarette end to move towards the inside of the receptacle; and   a receptacle having a single outlet, said single outlet associated with the inlet orifice, said receptacle extending substantially along the axis of the inlet orifice, the minimum length of said receptacle, along this axis, corresponding to that of a standard cigarette.
