Abstract

"Roll-your-own" cigarette are made in a conventional roller device from a charge of tobacco and a paper wrapper. The charge of tobacco is pre-proportioned by enclosing it in a tubular wrapper, which has abutting ends to define a radically-extending strip, thereby providing the charge of tobacco in a novel cartridge form. The tobacco cartridge is placed in the rolling device, the strip torn off and the rollers rolled to eject the remainder of the paper wrapper. The tobacco charge then is ready to receive the cigarette paper in conventional manner.

"Butler II"
PRO OEDURE FOR ASSEMBLY OF CIGAKh~
The present invention is directed to the assembly of cigarettes by individuals.
The assembly of cigarettes by the consumer has been known in various forms for a long time. One of the simplest procedures involves placing a charge of tobacco on a cigarette paper and then rolling it into a rod and sealing it. This procedure requires a degree of manual skill and is time consuming.
The procedure has been improved by a simple roller device comprising an endless belt and a pair of rollers mounted in a frame and within the endless belt. The rollers may be spaced apart to permit a charge of tobacco to be placed in a channel formed in the belt between the rollers. The rollers then are brought together to form a cavity in which the charge of tobacco is located.
The rollers are rolled to roll the tobacco charge into a rod and then a cigarette paper is introduced between the rollers and rolled into the cavity to - surround the rod, with the glue lap on the overlapping edge being moistened before entering the cavity to form the paper tube surrounding the tobacco charge.
one of the appeals of "roll-your-own" cigarettes is the lower cost of the resulting cigarette, since tobacco sold in loose form or some other inherently-unsmokeable form attracts a much lower excise tax than tobacco sold in the form of ready-to-smoke cigarettes in many jurisdictions, so that the cost to the smoker of the self-assembled cigarette is much lower than machine-assembled cigarettes.
One of the problems that the individual assembly of cigarettes encounters is obtaining a consistency in the quantity of the tobacco charge employed and hence obtaining a consistency in smoking quality.
In accordance with the present invention, a novel form of tobacco cartridge is provided which permits a 2~?J~ ~3 novel procedure to be provided for the assembly of "roll-your-own" cigarettes. The present invention utilizes a conventional roller device of the type described above in combination with such novel tobacco cartridge in such novel procedure.
In accordance with one aspect of the present invention, there is provided a novel tobacco cartridge comprising a tobacco charge, generally corresponding to the quantity desired in the finished cigarette, or a multiple thereof, preferably only lightly compressed, wrapped within an elongate tubular paper wrapper, usually conventional cigarette paper. The circumferential ends of the tubular wrapper are abutted and joined together to form an elongate strip.
This tobacco cartridge construction enables a measured or pre-proportioned quantity of tobacco to be incorporated into a cigarette, in the manner described below,'for a more uniform smoking quality.
The tobacco cartridge may be made on a conventional cigarette-making machine with suitable modifications to the wrapping procedure to result in the abutted ends, rather than conventional overlapping ends.
Hence, instead of the paper ends overlapping, as in the conventional cigarette, the ends of the paper wrapper abut one another and are glued together along their abul ~nt, either by a continuous glue line or by a number of glue spots, to provide a radially-extending strip of abutted cigarette paper.
The tobacco cartridge, therefore, is not a true cigarette and is not normally smokeable in that form, as a result of the radially-projecting strip, but is suited to enable cigarettes to be self-assembled.
Some means is provided associated with the paper strip, such as a tear tape, to permit the paper strip to be removed in a manner which breaks the glue line and hence separates the end of the paper wrapper.

rJ i ~

The tobacco cartridge is placed in the conventional roller device so that the paper strip extends from the nip between the roller elements. The paper strip then is torn off, so that the ends of the paper wrapper thereby are separated from one another. Rolling of the roller elements then ejects the torn paper wrapper from the roller device, leaving a tobacco charge of the correct and desired quantity in the roller device.
The tobacco charge, therefore, replaces the tobacco charge usually manually positioned by the smoker in the roller device. A conventional cigarette paper then is inserted and rolled in a conventional manner, the glue line moistened and the finished cigarette removed from the roller device.
Where the cigarette has been formed from a multiple lengths, for example, a double-length cartridge, the cigarette may be cut or otherwise divided into a multiple number of cigarettes of individual conventional lengths.
The plain-ended cigarettes that result from this procedure may be provided with a filter by assembly with the cigarette rod holder described in our copending Canadian Patent Application Serial No. 2,003,288-0 filed November 17, 1989. As described therein, a cigarette rod holder for a "roll-your-own" cigarette may comprise a conventional cigarette filter plug provided with a wrapper which extends for a short distance beyond the plug to provide a recess for receipt of the plain-ended cigarette. The tube may be of a length sufficient to hold ~he cigarette.
Alternatively, a length of filter material may be positioned in abutment with the filler rod in the roller device, and a length of cigarette paper sufficient to encompass the filler rod and filter element.

6~2~

The advantage that this procedure offers over the conventional "roll-your-own~ operation employing the conventional cigarette roller is that the charge of tobacco positioned in the roller and wrapped in the cigarette paper is predetermined by the quantity of tobacco in the cartridge and not subject to considerable variation, as is the case when the roll-your-own smoker changes the roller from a source of loose cut tobacco.
The smoker, therefore, is able to get consistent smoking qualities from a roll-your-own cigarette.
In summary of this disclosure, the present invention provides a novel procedure for the assembly of cigarettes by individuals using a conventional roller device which provides to the smoker a more uniform smoking quality from cigarette to cigarette.
Modifications are possible within the scope of this invention.

Claims (14)

1. A tobacco cartridge useful for forming self-made cigarettes, comprising:
an elongate tobacco filler rod, and an elongate tubular paper wrapper surrounding and enclosing said filler rod and having circumferential ends thereof abutting and joined together to form an elongate strip.
2. The cartridge of claim 1, wherein said tobacco filler rod contains a charge of tobacco corresponding to a quantity desired in a finished cigarette.
3. The cartridge of claim 1, wherein said tobacco filler rod contains a charge of tobacco corresponding to a multiple of a quantity desired in a finished cigarette.
4. The cartridge of claim 1, wherein said elongate strip extends generally radially from said cartridge.
5. The cartridge of claim 4, wherein said abutting circumferential ends are adhered continuously along their abutment.
6. The cartridge of claim 4, wherein said abutting circumferential ends are adhered at longitudinally-displaced locations along their abutment.
7. The tobacco cartridge of claim 1, wherein the filler rod is lightly compressed within the elongate wrapper.
8. The tobacco cartridge of claim 1, wherein said elongate wrapper is a conventional cigarette paper.
9. The tobacco cartridge of claim 8 including means associated with the paper strip to permit the paper strip to be removed from the remainder of the wrapper.
10. The tobacco cartridge of claim 9, wherein said removal means comprises a tear strip.
11. In a method of self-making cigarette wherein a charge of cut tobacco is loaded onto a rolling device comprising an endless belt and a pair of rollers located within the belt and a cigarette wrapping paper is fed between a nip formed by the rollers to wrap and enclose the charge of cut tobacco to form a cigarette, the improvement which comprises:
providing said charge of cut tobacco in the form of a tobacco cartridge comprising an elongate tobacco filler rod and an elongate tubular paper wrapper surrounding and enclosing said filler rod and having circumferential ends thereof abutting and joined together to form an elongate strip, positioning said tobacco cartridge in said rolling device with said strip protruding through the nip between the rollers, and removing the strip to separate the ends of the wrapper and rolling the rollers to eject residual wrapper, to provide said cut tobacco charge in said rolling device.
12. The method of claim 11, wherein said tobacco cartridge is of a length corresponding to a quantity of tobacco desired in a finished cigarette.
13. The method of claim 11, wherein said tobacco cartridge is of a length corresponding to a multiple of the quantity of tobacco desired in a finished cigarette, and individual lengths are severed from the resulting cigarette.
