United States Patent CHLOROPHYL IMPREGNATEDIFIL'I'ER MEANS non roa cco PRODUCTS Irving Flor-man, New York, N. Y. W Application May 21, 1952, Serial No. 289,123 i a 1 Claim. (Cl. 131-208) This invention relates to filter means for ucts and'smokers articles.

It is one of the objects of the present invention-1o pro,- vide means ensuring efiicient filtering of tobacco smoke and purification of the latter during smoking of. a tobacco product, such as a cigarette, cigar and the like.

It is a further object of the present invention to provide means facilitating the enlargement of the filtering surface of pliable filtering means as well as the enhancement of the effectiveness of the filtering means by imbuing or associating the same with a purifying medium, such as chlorophyl or chlorophyl compound.

Yet another object of the present invention is to provide means rendering the possibility of observing the utilization of the filtering means in a smokers article and ready replacement of said filtering means after the same has been used for a certain length of time.

Still another object of the present invention is to provide means permitting the combination of asbestos filtering means with a chlorophyl compound incorporated in said filtering means, whereby the latter is given more body and its filtering properties are considerably increased.

It is 'still another object of the present invention to provide means conducive to the manufacture of a relatively inexpensive filter material for use in tobacco products and smokers articles, which filter material, in conjunction with a water soluble chlorophyl derivative, brings tobacco prodabout increased cleansing, purifying and deodorizing qualities and substantially eliminates the bite from smoke without substantially impairing the taste of the tobacco.

Still a further object of the present invention is to provide .means contributing to the elimination of noxious constituents contained in tobacco and tobacco smoke andv simultaneously enhancing the flavor of the tobacco and reducing smoke odors and irritation from smoke to a negligible degree.

Theabove and otherobjects and features will become apparent from the following detailed description, reference being had to the accompanying drawing.

In the drawing:

Fig. 1 is a side elevational view partly in section of a cigarette holder embodying the invention;

ized from Fig. 3.

extension 18 with a transparent portion 19 extending between tubular extension 18 and end portion 20 of re- 'ceptor piece 12.

This transparent portion 19 may be glued to or in any other Way inserted or attached to the receptor piece 12 and its tubular extension 18. Tubular extension 18 and sleeve 16 define a filter housing 21 in which a filter 22 is inserted. This filter is made preferably from asbestos and has the finger pieces 22a, 22b, 220, etc., which meet rectangular form, as more clearly seen in Fig. 3.

These finger pieces are obtained by cutting thefilter strip 22 from one longitudinal edge to a position short of the other longitudinal edge 23, as can be clearly visual- The, asbestos filter piece 22 is pref erably imbued,saturated'or otherwise impregnatedwith I a suitable purifyingagent, such as chlorophyl or chloro:

. phyl compound, as hereinafterexplained.

the mouthpiece 11 extends a bore 14, whereas an aligned V bore 15 is provided in the receptor 12. The mouthpiece 11 has a sleeve-like extension 16 which terminates in inclined edge 17. The receptor piece 12 has a tubular -The thus impregnated asb estos strip 22 is then" rolled 1 up, as seen in Big. 4, and subsequently insertedinlfilter housing 21 in a manner as clearly indicated in Fig. 1 with the edge having slits 24 positioned in the direction from which the smoke is to be received.

The asbestos filaments may be combined with wood pulp, cotton fibers, blotting paper and like cellulose mate rial to give body to the asbestos strip. It is further preferred, according to the invention, to saturate or im-v pregnate such asbestos filaments with chloroplast or other fluid derivative of chlorophyl which is a great purifier, reduces irritation and eliminates odors. Instead of mineral filaments as just referred to other absorbent fibrous materials, such as glass wool or suitable synthetic (nylon) fibers may be employed either alone or combined.

By saturating the aforesaid asbestos filter material with a known soluble chlorophyl derivative, the cleansing and deodorizing qualities as Well as the filtering properties of apparel. While the asbestos filter removes tars and V nicotine, chlorophyl incorporated in such asbestos filter .j'- contributes-to an enhanced purifying action as regards tobacco smoke. a

Due to the fact that a strip of asbestos 22, as shown in Fig. 3, is provided with a plurality of slits 24, the filtering surface, as may be more apparent from Fig. 4, will be greatly enlarged, while the rolled up filter strip 22 permits easy handling of the filter for insertion in a filter housing of a cigarette holder, as hereinabove referred to.

Due to the slits 24, the filtering surface of the filtering material is greatly enlarged, which contributes to an improved filtering of tobacco products.

It is well understood that the asbestos filter means as herein disclosed may further be suitably treated with chlorophyl solution to eliminate nitrogen compounds present in tobacco smoke, which have a noxious effect on the smoker. Such nitrogen compounds may be pyridine,

empyreumatic oil and nicotine. withoutimpairing the aroma-imparting qualities of the smoke and flavor of the tobacco, which latter is rather enhanced due to the presence of chlorophyl.

. It can thus be seen'that therehas been provided acform or preferably in strip formation with enlarged filtering surfaces, as hereinabovedisclosedJ {twill beunderstood that: the filter is eapafile 50f inodi;
