Abstract
Procedures are described for self-manufacture of cigarettes. In one procedure, a preformed cigarette tube having a charge of cut tobacco therein has a recess at one end into which a filter is inserted to provide the finished cigarette. In another procedure, an inherently unsmokeable tobacco stick is coated with a material which renders the stick smokeable. In a further procedure, a plurality of short inherently-unsmokeable tobacco sticks is inserted into the hollow interior of a preformed cigarette paper tube.

ROLL-YOUR-C~WN CIaARET~ES
The present invention relates to novel structures useful in the formation of "roll-your-own" cigarettes.
Ihe large majority of cigarettes are sold as pre-formed cigarettes which can b~ smoked without further assembly or processing by the consumer. A minority of smokers prefer to assemble their o~n cigarettes, since ~obacco sold in ~n inherently-unsmo~eable form attracts a much lower rate of tax than in pre-formed cigarettes and hence is cheaper to purchase and the consumer is able to smoke more cigarettes for the same p~ice.
A variety of procedures have been used to form roll-your-own cigarettes, ranging from wrapping con~umer assembled tobacco filler rods in cigarette paper to inserting an inherently-unsmokeable pre-formed rod of tobacco into a preformed filter-tipped paper tube ha~ing a length to fully enclose the rod. In accordance with the prese~t. invention, there are provided a~ditional no~el ways of assembly of a cigarette for smoking.
In accordance wi~h an aspect of the lnvention, there is pro~ided an inherently-unsmokeable cigarette cornprising a tobacco rod and adjacent filter assembled in wrappin~ ~here the wrapping about the filter has a sufficiently high porosity to render the cigarette as inherently-unsmokeable.
In accordance with another aspect of th~ invention, there is provided a multiple of the inherently-unsmokeable cigarette element~ packaged for sale where each sold inherently-unsmckeable cigarette element may be rendered smokeable by a s~oker applyi~g a suitable coating ~eans to the sufficiently high ~rosit~ wrapping about the filter.
In accordance ~ith another aspect of the invention, there is provided a multiple of inherently-unsmokeable cigarette elements and a suita~le coatin~ means for such cigarette elements packaged for sale where each of the -_ la inherently-unsmokeable cigarette elements comprises a tobacco rod and adjacent filter assembled in wrapping where the wrapping about the filter has a sufficiently high porosity to render the cigarette element as sold as inherently-unsmokeable and the suitable coating means being for application ~y a smoker to the porous wrapping about the filter of each of the cigarette elements to render each ciga~ette ele~ent with coatins means applied thereto by a smoker as a smokeable cigarette.
In accordance with another embodiment of the invention, there is provided a method of forming a cigarette for smoking, which comprises pro~iding a cigarette rod comprising an outer cigarette wrapping paper enclosing a tobacco filler rod for a ~ubstantial proportion of the length thereof and defining a recess at one end of the rod, and in~erting a cigarette smoke filter into the recess to provide a cigarette.
In ~his embodiment of the invention, therefore, a pre-portioned tube alre~dy containing a charge of cut tobacco is provided which has an accommodation space for a filter and a filter, usually the same length as the accommodation space, is inserted into the filter accommodation space to provide the finished cigarette.
Perforations may be provided in the wall of the filter accommodation space to prevent the un-assembled 20112~4 _ 2 The filter may be fixed in place following its insertion into said recess by any convenient means, usually an adhesive. The adhesive may be such that it is normally dry on the outer surface of the filter and may be moistened immediately prior to assembly into the recess.
In accordance with another embodiment of the present invention, there is provided a method of forming a cigarette for smoking, which comprises providing an elongate inherently dimensionally stable element made only of smokeable material and having an air-permeable outer surface whereby the element is unsmokeable in that state, and coating the outer surface of the element with a layer of smokeable material to render the element smokeable.
In this embodiment of the invention, therefore, a wrapped tobacco stick which has a wrapping which is sufficiently porous as to prevent the stick from being smoked or other means of rendering the stick inherently unsmokeable is rendered smokeable by applying a suitable coating to the porous wrap. The coating, which may be of a wide variety of suitable materials, may be applied in any convenient manner, for example, by dipping the stick into a coating solution or by spraying the wrapper surface with a coating solution, and drying the wetted surface to a coating.
The inherently-unsmokeable tobacco element or stick may take any of the forms described in Canadian Patent No. 1,235,039. The charge of tobacco is usually located within a wrapper which has a sufficiently high porosity that the tobacco element cannot be smoked.
A tobacco smoke filter element may be attached to one end of the tobacco element or may be attached to the tobacco element following the coating step.
The tobacco element is rendered smokeable by coating the outer surface of the tobacco element with a -suitable material which will form a smokeable coating on the tobacco element.
In accordance with a further embodiment of this invention, there is provided a method of forming a cigarette, which comprises providing a plurality of preformed elongate inherently dimensionally and physically stable cut tobacco elements made only of smokeable material and having an air permeable outer surface whereby the element is unsmokeable in that 10 state, each of the elements having a length less than a normal cigarette length and such that a multiple number of the elements has a length corresponding to that of a normal cigarette; providing a preformed cigarette paper tube having a hollow interior; and sequentially 15 inserting individual ones of the plurality of tobacco elements into the hollow interior of the preformed cigarette paper tube to fill the same.
In this further embodiment of the invention, therefore, multiple discrete short lengths of inherently 20 non-smokeable tobacco sticks are inserted seriatim -into a preformed paper tube to abut each other in the tube.
The inherently unsmokeable tobacco element or stick may take any of the forms described in Canadian Patent No.
1,235,039. The charge of tobacco usually is located 25 within a wrapper which has a sufficiently high porosity that the tobacco element cannot be smoked.
Usually, each of the plurality of preformed tobacco elements or sticks are of the same length, for example, about 12 to 15 mm. The cut tobacco in the tobacco 30 elements or sticks may be the same tobacco blend or some or all of the tobacco element may be different tobacco blends.
The preformed cigarette paper tube generally comprises a tubular cigarette paper wrapper having a 35 cigarette smoke filter located at one end thereof and open to the hollow interior at the other. Such ~_ 4 preformed cigarette paper tubes are described in Canadian Patent No. 1,235,039 referred to above.
In summary of this disclosure, the present invention provides specific novel procedures for forming roll-your-own cigarettes. Modifications are possible within the scope of this invention.
