Abstract

An improved filter-type cigarette has a wrapper filled with tobacco and a special mouthpiece at one end. A non-tobacco filter is located within the wrapper behind the tobacco fill and is effective to absorb a maximal percentage of the combustion products of the tobacco. A non-absorbent, non-porous capsule is retained within the mouthpiece behind the filter and contains a small fill of aromatic tobacco. The capsule is perforated. In use, the filter entraps most of the undesirable constituents of the cigarette smoke but permits some hot smoke to pass through the filter and into and through the capsule. The hot smoke releases the volatile flavoring within the capsule. The process is enhanced by locating a thread or small ribbon of heat conductive material, such as aluminum, within the capsule to enhance heat and volatilization. Additionally, the flow passage through the cigarette is enhanced by providing a seal above the mating surface of the capsule in the internal surface of the mouth piece. The outer surface of the capsule also is roughened to preclude separation of the capsule from the mouthpiece.

Claims

1. A cigarette comprising:

a wrapper;

a long fill of tobacco extending inwardly from one end of the wrapper;

a non-tobacco filter disposed behind a long fill of tobacco and constructed to absorb a substantial percentage of the products of the combustion from the tobacco and to permit a highly filtered smoke to emerge therefrom;

a cup-shaped volatilization capsule disposed behind the filter and open in the direction of the filter, said capsule having a rear wall extending across the cross section of said capsule that closes the capsule at its rear end, said capsule being substantially non-absorbent and non-porous, said capsule having perforations formed in said rear wall thereof to enable the smoker to draw through it;

a short fill of aromatic tobacco disposed within the capsule to release volatiles in said capsule from said short fill of tobacco when said highly filtered smoke is introduced for flavoring said smoke after passing from said capsule from said filter;

a filament disposed solely within said capsule and being intertwined intimately throughout substantially the entire portion of said short fill of tobacco, said filament made of heat conductive material, said filament being effective to maintain the material within said capsule at an elevated temperature to accelerate the volatilization within said capsule.

2. A cigarette as defined in claim 1, wherein said wrapper terminates in a mouthpiece extension, said capsule being disposed concentrically within said mouthpiece extension and further comprising:

the external surface of said capsule wHich is in engagement with said mouthpiece being of a roughened texture.
