Description
This invention relates to filters for use with - . ~
smoXing articles and, more particularly, to filters for -~
use in cigarettes of the type which are manually formed ~
by rolling a quantity of loose tobacco in a paper -wrapper.
Although preformed or "ready made" cigarettes are readily available, a substantial segment of the smoking ;~
population prefers the manually formed or "roll your own" type of cigarette. This may be due to a preference to the type of tobacco which may be incorporated into this type of cigarette, or it may be for strictly economic reasons. Certainly, as the cost of preformed1` ; ~ ~;
cigarettes increases, more and more smokers are turning to the manual formed or ~roll your own" type of cigar~
ette in order to save cost. -~
There are also situations in which preformed ``
cigarettes are banned such as, fGr example, fore~try operations. Since preformed cigarettes include materi-als which promote burning so that they will not self- ~-extinguish, this type of cigarette is prohibited in areas where logging and other types of forest activities are conducted as these cigarettes, if dropped and not .`~
immediately extinguished, will continue to burn and ;
increase the risk of starting a forest fire. The manually formed type of cigarette which does not include ~ `
burn promotlng materials will self-extinguish very shortly after being dropped'.
Because of potentially harmful tar and nicotine substances present in cigarette smoke, various forms of -30 filtering has long been available to the purchaser of -preformed cigarettes. Additionally, separate filters are available for use with manually formed cigarette~
and, more particularly, cigarettes which are fashioned with a variety of mechanical devices. Many of these devices utilize a cigarette tube with pre-attached filter and includes means to act on the tube so as to "

compress tobacco therein. one example of such a ~ `~
mechanical device is disclosed in U.S. Patent 3,741,220.
Another type of mechanical device for forming cigarettes including attached filter is disclosed in -Canadian Patent 868,718 which issued April 20, 1971 to ~s Jesse H. Sledge. In Canadian Patent 868,718, a device is described which is adapted to form one or two ~ ~ -cigarettes each having an included filter. The patent `
describes the use of a specially designed wrapper paper having a cut portion which allows for the adhesive strip of the wrapper paper to contact the filter so as to ~ -positively hold it within the cigarette. The prior art, ~' however, does not disclose filters which are designed for use in cigarettes which are rolled manually without -the aid of any mechanical contrivances. Obviously, -~
manually forming or fashioning a cigarette which ~ -includes a filter utilizing materials available hereto~
fore require considerable dexterity to ensure proper `
location of the filter and the tobacco within the paper wrapper.
It is therefore an object of the present invention to provide a filter which overcomes the deficiencies of the present system. Broadly, the present invention relates to a filter for use with a smoking article, the `
filter comprising a fibrous core and a paper casing wherein the casing is provided with an adhesive zone.
The invention will now be described in greater detail with the aid of the attached drawings wherein~
FIGURE 1 is a perspective view of the filter; and, FIGURE 2 is a perspective view of the filter in as~ociation with a wrapper paper and tobacco.
FIGURE 3 is a perspective view of a wrapper paper of an alternate embodiment.
Referring to Figure 1 there is illustrated, in perspective, the filter in accordance with the present -invention. The filter comprises a porous core fabri-cated from material of the type which is normally found in preformed, filter cigarettes. The material is porous .
:: ' Z 0 0~ 225 and fibrous or foamed material such as, for example, cellulose acetate. This material is known to have --filtering characteristics which removes a substantial amount of the tars and nicotines which otherwise would be inhaled by the smoker. The porous core 12 is tightly wrapped with a paper casing 14 which helps to hold the filter together for ease of handling and storage. Paper casing 14 is a thin, good quality paper such as cigar~
ette wrapper paper. Suitably positioned on the outer surface of the paper casing is a zone of adhesive 16 of the type which becomes adhesive upon the application of moisture. It is contemplated that adhesive of the type which is normally found on a conventional cigarette wrapper paper would be utilized. It is important, of course, that the adhesive is non-toxic and must also be fast drying upon contact with the surface to which it is to be adhered.
As will be apparent from the foregoing and with particular reference to Figure 2, the filter 10 is adapted to be incorporated into a manually rolled cigarette during the rolling operation. The adhesive zone 16 on the filter is moistened so as to activate the adhesive and the filter 10 is then positioned generally within the fold 28 of a wrapper paper 20. The adhesive 16 causes the filter 10 to adhere to the wrapper paper 20 thus providing a sort of mandrel for use in the rolling operation. As shown in Figure 1, the adhesive ~ -zone 16 is preferably a longitudinal stripe of ap-proximately 4 mm in width. It is to be understood, however, that the adhesive strip need not run the full length of the filter and it can be wider or narrower than the preferred 4 mm.
The diameter of the filter is in the range of 4 mm -to 8 mm with an optimum diameter of 6 mm. The length of the filter is in the range of 8 mm to 20 mm with the optimum length being 12 mm.
- . .

;~00~22~ : ~
During the rolling operation, the adhesive zone 16 on the filter 10 is moistened and attached to wrapper paper 20 so that the outer end of the filter is general~
ly in line with the end of the wrapper paper and the filter lies generally in the fold thereof. A quantity of lose tobacco 24 is then placed in the remaining portion of the fold of the wrapper paper and the `-~
cigarette is rolled in the normal manner between thumb and index finger of both hands and sealed using moist- ~ -enable adhesive strip 22. The filter 10, after it has been fastened to the wrapper paper 20, creates a form around which the cigarette may be rolled. The filter 10, fastened to the wrapper paper 20, provides a secure ~urface against which the tobacco is abutted. The tobacco is apportioned into the paper with care not to pass the end of the filter. The filter secured to the paper acts as a roller bearing offering no impediment to the forming and shaping of the tobacco.
As indicated previously, the diameter of the filter 10 is preferably 6 mm which is the average diameter of a manually rolled cigarette. ~he preferred length of 12 ~; -mm provides an appropriate mouth piece and sufficient ;
filtration material to remove some of the suspended particulates in the smoke which passes through the filter. -;~
It will be readily appreciated that since the ;
diameter of the filter dictates the diameter of the rolled cigarette, the cigarette may be made smaller in diameter by reducing the diameter of the filter. Thus, 30 by utilizing filters in the range of 4 mm or less, the ~
quantity of the tobacco in a cigarette is reduced and, i hence, the cost.
.'''' ~' :
' ' ' 20~)~2Z5 In the foregoing description, it is assumed that -~ ~
the wrapper paper is of conventional design including an s ~-adhesive strip running lengthwise of the paper and at or very near to one longitudinal edge. The wrapper paper is, of course, folded with the fold line running along the longitudinal axis of the paper. It is understood that in rolling or manually forming the cigarette, the adhesive strip on the filter is moistened and the filter i8 placed in the fold of the wrapper paper at one end lO thereof with the adhesive strip positioned so as to contact the wrapper paper along the fold line.
As an alternative to the previously described embodiment, it is contemplated that the wrapper paper be provided with an additional strip of adhesive or an adhesive zone at or near the central fold line of the paper. Preferably, the adhesive zone will comprise a strip approximately 4 mm wide and will run along the fold line beginning at or very near to one end of the wrapper paper and extend along the fold line, a length of from about 8 mm to 20 mm. A preferred length is 12 mm.
As illustrated in Figure 3, wrapper paper 30 is of conventional shape and design including adhesive strip i `
32 and fold line 34. Wrapper paper 30 does, however, include additional adhesive zone 36 which, as discussed hereinbefore, is located along fold line 34 and begins `
at or very near to one end 38. As in the previously described embodiment, loose tobacco 24 is positioned in ~`
fold 34 after the filter is installed and the cigarette is rolled between thumb and index finger of both hands in the normal manner.
It should be understood that the descriptive embodiments of the invention as set forth herein are illustrative only and the concepts of this invention are not limited thereby except as defined in the appended claims.
