CIGARETTE AND METHOD OF MAKING THE SAME Filed April 26, 1952 OOOOOOOOOOOOOOOIOOOQO OOOOOOOOOOOOOOOO IN VEN TOR. Chas/7, Swarm ATTORNEY United States Patent Oflice CIGARETTE AND METHOD OF MAKING THE SAME Charles H. Swain, Minneapolis, Minn. Application April 26, 1952, Serial No. 284,497

7 Claims. (Cl. 131-4) This invention relates to a cigarette having a noncombustible wrapper and more particularly to a cigarette having a form-retaining noncombustible wrapper adapted to hold the ash therein until the tobacco in the wrapper is consumed. Said wrapper is also adapted to provide an immediate source of air to support the burning of the tobacco therein and to provide ventilation to cool the hot gases or air therein so that the same may be substantially cooled before being drawn into the mouth of the smoker.

It is an object of this invention to provide a cigarette having a wrapper made of a noncombustible sheet material adapted to become porous or apertured when affected by the burning of tobacco therein whereby an immediate source of air is present to support the combustion of the tobacco in said wrapper.

It is another object of this invention to provide a cigarette having a wrapper made of a form-retaining noncombustible sheet material adapted to become apertured when affected by the coals of the tobacco burning therein whereby said porous or apertured condition moves continuously closer to the mouth end of the cigarette as the same is consumed and the ash resulting from the burning tobacco is retained in said wrapper.

It is more specifically an object of this invention to provide a cigarette having a wrapper made of a formretaining non-combustible sheet material adapted to have a multiplicity of apertures therein spaced circumferentially and longitudinally of said wrapper, a readily combustible material filling said apertures, the outer end of said wrapper having an apertured closure, whereby the tobacco in the wrapper is ignited at said closed end and as the tobacco burns towards the mouth end of the cigarette the material filling said apertures is consumed by the burning coals of the tobacco, thereby providing an immediate source of air to support the combustion of said tobacco and providing a means of ventilation for the hot air and gases produced in said wrapper whereby the same may be substantially cooled before being drawn into the mouth of the smoker.

It is still another object of this invention to provide a novel cigarette and method of making the same.

It is an additional object of this invention to provide a novel cigarette wrapper and method of making the same.

2,754,828 Patented July 17, 1956 Referring to the drawings, a cigarette 10 is shown. With reference to Fig. 3, tobacco 11 is shown which is used as av filler in forming said cigarette. A wrapper 12 is shown in Fig. 5 in a developed view and in Fig. 1 as having an elongated tubular form enclosing said tobacco 11 to form cigarette 10. Said wrapper may be made of any suitable noncombustible sheet material but in the embodiment of the invention as illustrated, said sheet material is shown to be a thin sheet of asbestos paper. Said wrapper is adapted to become porous or apertured when and as affected by the heat of the tobacco burning therein. In the embodiment of the invention as illustrated, said wrapper is shown as having a multiplicity of apertures 12a. Referring to Fig. 1, said apertures are shown as being circurhferentially and longitudinally spaced in said wrapper. As shown in Fig. 3, said apertures are shown spaced to form a pattern and as here illustrated, a specific pattern is shown. Disposed in said apertures and filling the same is a readily combustible material 13, and while different materials might be used, in the embodiment of the invention disclosed and in practice said material has been cellulose fibers. The side edge portions 12b of said wrapper overlap and said edge portions are secured together by a suitable adhesive. Covering the outer end of said cigarette is a disc-like closure 14 made of some suitable noncombustible material which could be the same as that of said wrapper. Said closure has a multiplicity of openings 14a therein. Flap portions 12c are provided at the outer end portion of said wrapper 12 and the same are turned inwardly to be at right angles to said wrapper. Said end piece is secured to the outer sides of said flaps preferably by an adhesive.

In operation and in carrying out the method of the invention, a wrapper 12 is formed of a sheet of noncombustible material and said wrapper is substantially rectangular.

Said wrapper is then perforated with a multiplicity of small holes 12a. Said holes are in spaced relationand may be arranged as shown in Fig. 5 to form characters such as letters. Said holes are then filled with a readily combustible material 13.

Said wrapper 12 is then disposed around a tobacco filler 11 to form a substantially cylindrical cigarette. The side portions of the wrapper are overlapped and are secured by a suitable adhesive.

Said wrapper has flap portions at one end and the same are turned inwardly. A disc-like closure 14 is placed against said flaps and over said end of said cigarette. Said closure is secured to said flap portions by a suitable adhesive. This closes one end of said cigarette. Said closure 14 is perforated to have a plurality of small openings therein.

The cigarette is lighted at the outer end and air is drawn inwardly through said openings 14a in the end closure 14 of said wrapper, which openings provide a source of air and permit a sufiicient draft to be caused for igniting the tobacco in the cigarette. As the tobacco is burned, the combustible filler material 13 in the apertures immediately adjacent the burning tobacco will be consumed and thus said apertures 12a will be opened. Said apertures will thus provide an immediate source of air to support the burning of the tobacco. Also when the smoker draws on the cigarette, air will be drawn through the apertures adjacent the burning portion of the cigarette and also through those about the used portion of the cigarette and said air entering into said wrapper will serve to reduce the heat generated within the wrapper and said air has a considerable cooling effect on the fumes that are drawn into the smokers mouth by the action of smoking. During the interval of time when the smoker is not drawing inwardly on the cigarette the heated air within the wrapper will escape through the opened apertures in the upper portion of the Wrapper and the incoming supply of air will enter through the opened apertures in the lower portion of the wrapper. Thus there is a constant change of air within the portion of thewrapper in which the tobacco is being and has already been consumed. As the tobacco in the wrapper is consumed, the resulting ash will be retained within the wrapper and the perforations will be of such size that said ash will not escape therethrough. The ash is substantially porous and it will not obstruct ventilation of the wrapper. Said wrapper is adapted to be shape-retaining throughout the entire period of time during which the cigarette is used. Hence the dropping of ashes is entirely eliminated and the smoker need have no concern regarding the cigarette or the disposal of any ash until all of the tobacco in the wrapper has been consumed. When this has been done the wrapper may be disposed of along with the ash which has been retained therein. As said cigarette is being consumed, said filled apertures in said wrapper are opened from the outer end of said cigarette towards the mouth end of said cigarette. Hence as shown in the embodiment of the invention as illustrated in Fig. 5, said apertures may be spaced so that when they are opened, said openings will form a specific pattern, and as here illustrated, the letters ABC are formed.

Thus it is seen that I have provided a very useful invention in a cigarette and method of making the same. The cigarette has the substantial utility of retaining therein the ash resulting from the smoking of a cigarette. This important function obviates the nuisance and the danger of damage and fire resulting from dropping ashes and makes unnecessary any attention being given the cigarette until it has been entirely consumed. This wrapper has been found to be very eflicient and entirely satisfactory in actual use.

It will of course be understood that various changes may be made in the form, details, arrangement and proportions of the parts, Without departing from the scope of applicants invention, which generally stated, consists in a device capable of carrying out the objects above set forth, in the parts and combinations of parts disclosed and defined in the appended claims.
