Abstract
A smoker's requisite for reducing the amount of smoke given off by the smouldering tip of a cigarette. The requisite consists of a rigid sleeve that may be slid along a cigarette and momentarily positioned over the smouldering tip thereof then withdrawn to enable the smoker to take a puff from the opposite end in a conventional way. The sleeve advantageously comprises a finger engaging gripping and supporting portion providing ventilation of the cigarette body, and a briar wood portion designed to be controllably moved over the smouldering tip.

Requisite for reducing the quantity of smoke emanating from the smoldering tip of a cigarette consisting of an elongated ring whose circular hole enables the aforesaid ring to slide with friction along the aforesaid cigarette, under the influence of the fingers of the user, characterized in that the ring comprises at least a proximal part to be oriented on the side for inhaling the cigarette, made of a dimensionally stable material, and a distal part destined to receive or be close to the smoldering tip of the cigarette made of a different material, utilized for manufacturing pipe bowls, wherein the proximal part comprises holes traversing the wall and enabling the ventilation of the body of the cigarette under this segment, the perforated surface of the proximal segment being greater than 20%, the distal part being imperforate.
A cylindrical sleeve for reducing the quantity of smoke emanating from the smoldering tip of a cigarette consisting of an elongated ring whose circular hole enables the aforesaid ring to slide with friction along the aforesaid cigarette, under the influence of the fingers of the uses, wherein the ring comprises at least a perforated proximal part to be oriented on the side for inhaling the cigarette, made of a dimensionally stable material, and an imperforate distal part destined to receive or be close to the smoldering tip of the cigarette made of a different material, said material being selected from the group consisting of wood, meerschaum or terra cotta, and wherein the proximal part comprises a cylindrical wall having holes traversing the wall which form a perforated surface that comprises 20% or more of the proximal segment.
