United States Patent 3821958

A cigarette of improved type, and which is centrally contained within a tubular sleeve or case so to enclose the cigarette flame for preventing accidental fires, the case having a front end wall that is perforated so to allow igniting the cigarette and admit air for maintaining the cigarette flame. The cigarette may be ignited by means of an elongated member extending through the front end wall, the member having a portion arranged to cover the perforations in the end wall and being lightly adhered thereto before use; the cigarette having its front end coated with a ring of ignitable material and the rear end portion of the elongated member having an enlarged abrasive surface thereon on such that the abrasive material will cause ignition of the cigarette end upon relative axial movement thereof.

1. Field of the Invention

This invention relates to smoking cigarettes.

2. Description of the Prior Art

It is generally well known that many fires are started due to careless use of cigarettes. Upon many occasions it is known that cigarette smokers fall asleep while smoking and thus cause a dropped cigarette to begin a fire, thus endangering human lives. This is a serious situation in need of improvement.

It is therefore a principal object of the present invention to provide an improved cigarette wherein the cigarette flame is enclosed and thus being impossible to be contacted by other objects that are subject to burn.

Another object of the present invention is to provide an improved cigarette which incorporates a fire-proof case formed around a conventional cigarette, the end of the case being perforated with small openings so as to allow a match flame to gain access to the end of the cigarette tobacco for igniting the same.

Yet a further object of the present invention is to provide an improved cigarette wherein the case will retain the ashes which drop off the end of the cigarette and thus prevent the ashes from soiling a carpet or other objects upon which the same might otherwise be dropped.

Other objects of the present invention are to provide an improved cigarette which is simple in design, inexpensive to manufacture, rugged in construction, easy to use, and efficient in operation.


One embodiment of the present invention is a fire-proof and ash-proof cigarette comprising a perforated hollow case, a conventional cigarette member mounted centrally within the case, and igniting means mounted within the case for the ignition of the cigarette member.

It is an object of the present invention to provide a fire-proof and ash-proof cigarette.

A further object of the present invention is to provide such a cigarette having self-contained igniting means.

Related objects and advantages of the present invention will be apparent from the following description.


FIG. 1 is a perspective view of the present invention.

FIG. 2 is a cross-sectional view taken on the line 2--2 of FIG. 1.

FIG. 3 is a cross-sectional view taken on the line 3--3 of FIG. 2.

FIG. 4 is a cross-sectional view of a modified design of the invention.

FIGS. 5 and 6 are partial perspective views and show steps in igniting the cigarette shown in FIG. 4.


For the purposes of promoting an understanding of the principles of the invention, reference will now be made to the embodiment illustrated in the drawings, and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of the invention is thereby intended, such alterations and further modifications in the illustrated device, and such further applications of the principles of the invention as illustrated therein being contemplated as would normally occur to one skilled in the art to which the invention relates.

Referring now to FIG. 1 to 3 in detail, the reference numeral 10 represents a fire-proof cigarette according to the present invention, wherein there is a conventional cigarette member 11 and an enclosing case 12.

The conventional cigarette 11 is comprised of a quantity of tobacco 13 wrapped within a roll of cigarette paper 14, one end of which encloses a conventional filter 15.

In the present invention, the case 12 comprises a tubular member of slightly larger diametrical dimensions than the outer diameter of the cigarette 11 so as to provide a space 16 therebetween all around the cigarette. The case 12 may be made of any fire-proof material such as fiberglass or metal foil, and can be in any color like lipstick cases. The end wall 17 of the case is provided with a plurality of small perforations or openings 18 so as to admit air therethrough, while the cigarette is being smoked, and also serve for a flame of a match placed in front thereof to ignite the cigarette.

The opposite end 19 of the case is constricted and secured around the outer side of the cigarette 11.

In operative use the space 16 around the paper 14 will insulate the case and thus allow the case to be held between a person's fingers without burning himself. A plurality of openings 20 are formed along the side of the case 12 so as to improve the draw of air during the smoking operation. Each successive opening 20 is relatively smaller than an adjacent opening.

Referring now to FIGS. 4 through 6, a fire-proof cigarette 21 includes the principle of the above features and additionally includes a tab 22 attached by pressure sensitive adhesive to a front side of end wall 17 so to close the perforated openings and thus maintain the tobacco fresh from drying until ready to smoke, when the tab is peeled off as shown in FIG. 5, and then pulled straight forwardly as shown in FIG. 6 so that a match 23 integral with the tab is pulled out of the case through an opening 24. As the match is pulled out, it ignites the cigarette, thus eliminating need of exterior flame. Thus all flamge is confined inside the case for increased safety. The match end has an abrasive sand paper material 25, while a ring of ignitable phosphorous 26 is applied around the forward part of the cigarette so that as the abrasive moves past the phosphorous it ignites. The match thus carries no flame as it is pulled out.

While the invention has been illustrated and described in detail in the drawings and foregoing description, the same is to be considered as illustrative and not restrictive in character, it being understood that only the preferred embodiments have been shown and described and that all changes and modifications that come within the spirit of the invention are desired to be protected.
