Description

L. N. GOULD FILTER CIGAR Sept. 1s, 1962 Filed oct. 19, 1960 INVENTOR. LEWIS N. GOULD BY ATTOP/VZ'V Sttes This invention concerns a cigar with a iilter tip.

According to the invention there is provided a cigar to the mouth end of which is applied a filter tip. The tip is formed as a tubular member secured to the cigar. Within the tubular member is a cylindrical Ibody of porous material which serves as a filter to extract nicotine, tars and solid particles from the tobacco smoke passing therethrough. The filter tip renders the cigar cleaner and more comfortable to hold in the mouth than a bare cigar tip. The iilter tip absorbs tobacco juices, prevents disintegration of the mouth end of the cigar and permits the cigar to be smoked more completely. The porous lter material may be made of various vegetable or synthetic iibers, Fiberglas, rock wool, cellulose, charcoal activated powdered material such as kaolin, or the like.

It is therefore one object of the invention to provide a cigar with an improved lter tip.

Itis a further object to provide a filter tip for a cigar.

It is another object to provide a. exible tubular attachment for a cigar, said attachment containing a body of porous filter material.

For 'further `comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure:

FIG. 1 is a perspective view of a cigar invention.

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

FIG. 3 is a sectional view similar to a portion of FIG. 1 showing a further embodiment of the invention.

FIG. 4 is a perspective View of a portion of another cigar embodying another modification of the invention.

FIG. 5 is a longitudinal sectional view taken on line 5-5 of FIG. 4.

FIG. 6 is a perspective view of the portion of the cigar of FIGS. 4 and 5 showing the form assumed thereby during use.

FIG. 7 is a view similar to FIG. tion of the invention.

FIG. 8 is a sectional view taken on line 8-8 of FIG. 7.

FIG. 9 is a perspective View of a filter tip alone according to the invention.

Referring to FIGS. 1 and 2, there is shown a cigar 10 having a generally cylindrical body 12 formed of tobacco leaves rolled in conventional fashion. At the mouth end 14 of the cigar is secured a exible tubular jacket 16 formed of non-porous, moisture-proof plastic or paper material. The jacket may be secured to the mouth end of the cigar by a suitable adhesive 18. Within the tubular jacket is a cylindrical body of porous filter material. This body may be enclosed in a tubular paper wrapper 22.

The iilter tip T including jacket 16 and the porous body 20 may be assembled prior to mounting on the mouth end of the cigar body. The portion of the jacket extending beyond the body 20 defines a recess 21 which fits snugly on the mouth end of the cigar.

In FIG. 3 the lter tip T includes a tubular paper jacket 16a coated or covered by a non-porous layer 17 of synthetic resin or plastic material such as polyethylene, vinyl embodying the 4 of another modicarzice or the like. Adhesive 18 secures the tip T to the cigar body 12a.

In FIGS. 4 and 5 the lilter tip T has a pliable jacket 16b formed with a closed end 25 in which are a plurality of parallel spaced slits 26. The closed end of the jacket keeps the porous filter `body 20 more securely within the jacket prior to and during smoking of the cigar. When the cigar is to be smoked, the smoker initially closes his teeth on the jacket which compresses it -at its end 27 to flattened -or oval form `as shown in FIG. 6. This causes the slits 26 to spread 4and form openings 26' through which the smoke passes while the cigar is being smoked. The ilter tip retains its attened or oval form while being smoked primarily due to the pliable nature of the jacket. 'Ihe jacket may be made of metal foil, or a non-porous plastic material which is pliable and shape-retaining when pressed. The jacket overlays the paper layer wrapper 22. If desired, this wrapper may be omitted and the porous body 20 may be packed in the jacket alone. Adhesive 18 secures the jacket to the mouth end 14 of the cigar body 12b.

In FIGS. 7 and 8 the structure of the jacket 16c is like jacket 16b with closed end 25 and slits 26. Adhesive is omitted and the inner end of the jacket is formed with annular ribs or corrugations 23 which eectively secure the filter tip F to the mouth end of the cigar body 12C. Jacket 16c is made of metal foil.

In all the embodiments of the invention, the lter tip is flexible so that it can be comfortably held between the lips or teeth of the smoker. The porous body 20 is preferably non-combustible and may be made of Iibers of Fiberglas or rock wool. However, organic materia-ls such as cellulose fiber may be used. Granulated or compressed powdered materials may also be employed. In any case the filter material should have good moisture absorbency and should be chemically inert to avoid giving oi fumes when the smoke passes through.

The provision of filter tips as described makes cigar smoking more enjoyable, cleaner `and more satisfying. The filter tips can be fabricated and -applied by conventional, high speed mass production at low cost.

If desired, the filter tips can be fabricated as separate units as shown by tip F in FIG. 9, and sold separately for assembly on a conventional cigar made without lter tip. The smoker can apply the iilter tip by moistening the mouth end of the cigar and pushing on the mouth end of the cigar into the recess 21 in jacket 16d Where the adhesive will become moistened to secure the iilter tip of the cigar.

Another improvement of the invention may be made with a pre-formed iilter in which the iilter itself may be tobacco with pre-treated filtering material or powder which may be dipped into plastic or Ilatex liquid to cover the same and to form a protected cigar mouth tip.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and that various changes and modifications may be made within the scope of the invention -as defined in the appended claims.

Having thus described new, and desire to secure 1s:

1. A cigar comprising an elongated generally cylindricd body of rolled tobacco leaves having a mouth end of reduced diameter, a flexible tubular moisture-proof jacket having one end secured to said mouth end by an adhesive and extending outwardly axially from said mouth end, and a porous filter enclosed in a paper wrapper fitted in said jacket for filtering smoke passing therethrough, said jacket having ya closed end formed with a plurality of transverse my invention, What I claim as by United States Letters Patent normally closed slits, said packet being pliable so that the slits are adapted to open upon compression of the jacket.

2. As an article of manufacture, a filter tip for a cigar comprising a tubular body of flexible moisture-proof material, a cylindrical lbody of porous material enclosed in said tubular body and terminating short of one end to dene a recess adapted to receive the mouth end of the cigar, and a layer of adhesive lining the tubular body at said one end for securing the lter tip to the cigar, the other end of said tubular body being closed and having transverse slits normally closed therein, said tubular body being pliable so that the slits are adapted to open upon compression of the jacket.
