Abstract
Abstract A filtering pipe of housing with built in extinguisher for cigarettes, such that the lighted ash of the cigarette is extinguished, as it communicates with a non-flammable, extinguishing portion of the filter. The filter includes an elongated housing, having a filter at the mouthpiece end and a ring of non-flammable, extinguishing material at the cigarette supporting end. A cigarette to be smoked is pushed outwardly of the housing such that the extinguishing ring abuts that portion of the cigarette where the lighted ash is to be extinguished.

Total Claims: 11
Claim 1
Independent Claim
109 words
A filtering pipe with extinguisher for cigarettes comprising: (A) an elongated housing, defining a mouthpiece end and a cigarette supporting end said housing being of tubular configuration and having an inner diameter approximating the outer diameter of a cigarette; (B) an inner collar supported within said mouthpiece end, so as to engage the outer diameter of a cigarette wedged therein, while serving as a locking abutment with an annular ring of non-flammable extinguishing material as a cigarette is withdrawn from said housing; (C) a filter supported within said mouthpiece end; (D) a non-flammable extinguishing material supported upon said annular ring mounted within the inside of said cigarette supporting end.
Claim 2
Dependent Claim
109 words
A filtering pipe with extinguisher for cigarettes comprising: (A) an elongated housing, defining a mouthpiece end and a cigarette supporting end said housing being of tubular configuration and having an inner diameter approximating the outer diameter of a cigarette; (B) an inner collar supported within said mouthpiece end, so as to engage the outer diameter of a cigarette wedged therein, while serving as a locking abutment with an annular ring of non-flammable extinguishing material as a cigarette is withdrawn from said housing; (C) a filter supported within said mouthpiece end; (D) a non-flammable extinguishing material supported upon said annular ring mounted within the inside of said cigarette supporting end.
