filter cigarillo

The invention relates to a filter cigarillo with tobacco, a filter in the mouth-side end region and a cover sheet which extends over the entire length of the filter cigarillo.

Conventional filter cigarillos have a tobacco rod, which is usually surrounded by a binder and a cover sheet arranged above. At one end of the strand of the filter using a so-called tipping paper (filter pad) is connected to the strand. In such Filtercigarillos can be seen at first glance, at which end of the filter is arranged so that the user can light the Filtercigarillo easily at the right end.

According to a new regulation (EU Directive 2002/10 / EC dated 12.02.2002), the cover sheet covers the entire length of ge of the filter cigarillo. For these products, the filter is fixed with the tipping paper to the strand wrapped in the binder and then completely covered by the cover. This poses the problem that the user has to look very carefully at which end of the filter cigarillo the filter is located. For example, if the filter has cellulose acetate that is almost white, the end with the filter still can be distinguished by the color of the face from the other end of the filter cigarillo. But there are also tobacco filter conceivable, ie filters made of tobacco, which makes a distinction between the two ends of the filter cigarillo very difficult.

It is an object of the invention to provide a way to even in a Filtercigarillo the two ends without further teres to distinguish when the cover sheet extends over the entire length of the filter cigarillo.

This object is achieved by a Filtercigarillo with the features of claim 1. Advantageous embodiments of the invention will become apparent from the dependent claims.

The filter cigarillo according to the invention contains tobacco and a filter in its mouth-side end region. The outer wrapper is a cover sheet which extends over the entire length of the filter cigarillo. Preferably, the tobacco is surrounded by a binder below the cover sheet, wherein the filter is connected by means of a filter pad with the tobacco leaf wrapped by the binder. According to the invention, a banderole-like marking is provided which is arranged on the mouth-side half of the cover sheet and leaves free the mouth-side end (or the mouth-side end region) of the filter cigarillo.

The location of the banderole-like marking points easily to the orientation of the filter cigarillo and the location of its mouth-side end. Since the mouth end itself is not is covered by the banderole-like marking, the properties of the filter cigarillo are not affected by the banderole-like marking in the end region which is relatively important for smoking behavior.

In an advantageous embodiment, the banderole-like marking is designed as a banderole, which extends over the entire circumference of the cover sheet. In this case, the band can be made as a separate part and fixed to the cover sheet, e.g. by gluing, preferably by full-surface gluing with the cover sheet. The banderole can also be tightly placed around the cover sheet and fixed to itself so that it can not slip or be pulled over the cover sheet away. As a material for the band come, for example Paper, reconstituted tobacco and film material in question, also transparent film material such. Cellophane. The band can also be self-extinguishing equipped to prevent the filter cigarillo from burning completely by mistake. This is achieved, for example, by the addition of fire retardants (such as alginates, cellulose, salts). In preferred embodiments of the invention, the band is printed.

The banderole-like marking need not be formed as an independent part, but may also be printed on the cover sheet of the filter cigarillo.

As printing techniques for banderol printing, both gravure printing, offset printing or high-pressure printing (including flexographic printing and stamp printing) are suitable both for an independent printing banderole and for an imprinted marking. Banderol printing can be done "on-line" by printing the cover sheet or a bander already wrapped around and attached to the cover sheet in the desired manner during the manufacture of the filter cigarillo. In the latter case, the ban - A -

derole before being attached to the cover sheet also already been provided with other imprints or markings. An "off-line" method is particularly suitable for stand-alone bands, e.g. printed on sheets or endless tapes adhering to each other and then separated and attached to the cover sheet of Filtercigarillos.

Preferably, the banderole-type marker is decorative, e.g. with a logo. It may also be printed with a warning, an advertisement or a tamper-evident notice or otherwise marked. Holograms are also suitable as markings. A simple banderole-type label, e.g. monochrome or with mutually parallel colored stripes that extends over the circumference of the cigarillo Fiil-, is also conceivable.

The width of the banding-type marking may be e.g. ranging from 3 mm to 16 mm. Through this information, all intermediate values are also disclosed. Particularly advantageous is a width of about 8 mm. However, the longitudinal sides of the banderole-like marking (that is, the sides running in the circumferential direction of the filter cigarillo) do not have to be straight or run parallel to one another.

The zone of the topsheet between the mouth-side end of the filter cigarillo and the banderole-type marking may e.g. have a width in the range of 10 mm to 30 mm, whereby also all intermediate areas are disclosed, e.g. 17 mm to 19 mm or about 18 mm.

In preferred embodiments, the filter cigarillo has a ventilation zone with ventilation openings. The ventilation openings can be produced, for example, by laser perforation or mechanical perforation. The ventilation zone may, for example, in a range of 9 mm to 30 mm from the mouth End of the filter cigarillo (which also includes a small portion thereof or, for example, a circumferentially extending perforation line extending over the full circumference or a portion thereof) or an intermediate portion thereof. In one embodiment, the ventilation zone is located outside the filtration area at a distance of 0 mm to 40 mm (or a portion thereof) from the upstream end of the filter, that is from the end at which the tobacco rod begins. However, it does not have to be restricted to the tobacco rod (strand ventilation), but can also be arranged additionally or exclusively in the filter region. The ventilation zone may, for example, have one, two or more than two circumferential perforation lines, but other configurations are conceivable.

The ventilation zone is preferably dimensioned such that target values or potential regulatory limit values during smoking (in particular according to "Coresta recommended method" No. 64-67 or according to DIN / ISO) are maintained or undershot. The degree of ventilation may range from 10% to 90%, with also all intermediate values being disclosed (e.g., 30% to 70%, 30% to 50%, 10% to 30%, 70% to 90%).

Under certain circumstances, a ventilation zone in the mouth-side end region of the filter cage is hardly visible to the naked eye. Also, because of the wrapping with the cover sheet, it can not be seen at which point the smokable tobacco rod ends and the filter portion begins. By placing the banderole-like marking, however, the invention makes it possible to identify the rough area at which point the filtration area (with ventilation zone and filter material) begins or the area intended for smoking ends. The filter has, for example, a length in the range of 4 mm to 30 mm, whereby also all intermediate areas are disclosed with. A filter length of about 7 mm to 8 mm is advantageous.

The filter can be made of a conventional filter material, such as cellulose acetate, but also regenerated cellulose

(e.g., viscose). Other conceivable materials are e.g. Cellulose or paper. Further, additives such as e.g. on

Adsorbent, activated carbon or an ion exchanger can be provided. A particular advantage of the filter cigarillo according to the invention is shown when the filter has tobacco, since in this case the front ends of the filter cigarillo practically do not differ. A tobacco filter may e.g. can also be manufactured by the tobacco strand is compressed in a region which is provided as a filter zone during the production of the filter cigarillo. The filter may also have a hollow mouthpiece. Multi-part filters are also conceivable.

The overall length and diameter of the filter cigarillo may be varied over a wide range, e.g. 65 mm to 120 mm for the total length and 5 mm to 12 mm for the diameter. As a result, all intermediate values are also disclosed. Preferred values for the total length are about 84 mm and about 100 mm. The diameter may e.g. about 8 mm. In another embodiment, the diameter is greater than or equal to 10.8 mm (i.e., circumference greater than or equal to 34 mm).

Any cigarillos tobacco can be used as tobacco, eg stripped mixed tobacco. In a preferred embodiment, mixtures typical of cigartts can also be used, for example with Burley, Virginia and / or Oriental tobaccos, which can also be used as stripped mixed tobacco. The mass of the tobacco material contained in the filter cigarillo is, for example, in the range of 0.5 g to 3.0 g or at an intermediate value thereof, and is preferably either greater than (or equal to) 1.2 g or greater than (or equal to) 2, 3 g. In this case, the mass refers to the entire tobacco material, ie the tobacco intended for smoking in the tobacco rod and any tobacco (eg reconstituted tobacco) in the binder and / or cover sheet. Embodiments with a tobacco mass of 2.3 g or more are particularly suitable for filter cigarillos which have no binder and in which the cover sheet is wound axially (ie not helically); In this case, the diameter is preferably at least 10.8 mm (ie, the circumference is at least 34 mm).

The cover sheet of the filter cigarillo may (as well as the binder) have reconstituted tobacco. Preferably, the cover sheet is wound helical. An advantageous pitch angle of the winding is about 30 ° (measured with respect to the longitudinal axis of the filter cigarillo, the pitch angle is defined differently here than with a screw thread). It is also conceivable that the cover sheet is not wendelartig wound. A helically wrapped cover sheet can also be designed as a natural cover sheet, so in particular be made of a tobacco leaf.

The banderole-like marking allows the filter cigarillo according to the invention a fast and reliable distinction of the end provided with the filter of the end to be ignited. Furthermore, the banderole-like marking can make clear a ventilation zone, so that the observation of boundary values is ensured during smoking, and it can clarify the position of the filtration zone with respect to the zone intended for smoking. In addition, the banderole-type marking provides a possibility to remove the filter cigarettes. Io in an appealing way to make or distinguish from cigarettes.

In the following the invention will be further described by an embodiment. The drawing shows in

1 shows a schematic longitudinal section through an embodiment of the filter cigarillo according to the invention.

FIG. 1 shows an embodiment of a filter cigarillo 1 in a schematic longitudinal section. Figure 1 is not to scale; e.g. the material thicknesses are displayed too high.

The Filtercigarillo 1 has a mouth-side end 2 and a strand-side end 3. As a filling is formed into a tobacco rod shaped tobacco 4. In the exemplary embodiment, the tobacco 4 is a stripped mixed tobacco, as used for filter cigarillos. The tobacco can be made from a mixture of Burley, Virginia and Oriental tobaccos.

The tobacco 4 is surrounded by a binder 6, which consists in the embodiment of reconstituted tobacco. The binder 6 is wound axially (ie not helically) and closed at a longitudinal seam, not shown in Figure 1, which is designed as an adhesive seam.

At the end of the tobacco rod facing away from the strand-side end 3, a filter 8 is arranged, which has cellulose acetate in the exemplary embodiment. Other filter materials, such as regenerated cellulose, paper or tobacco, are also conceivable. To attach the filter 8 to the wrapped by the binder 6 tobacco rod is a filter pad 10 made of paper (Tippingpapier), which is longer in the axial direction than the filter 8 and thus overlaps with the binder 6. The Fii- Terbelag 10 is glued to the binder 6. The filter pad can also be made of a material other than paper, for example made of reconstituted tobacco.

A cover sheet 12 is provided as an outer cover. In the embodiment, the cover sheet 12 is also made of reconstituted tobacco. It is wound like a helix, as indicated in Figure 1 by the oblique lines. According to recent regulations, the cover sheet 12 completely covers the filter pad 10, as is the case with the embodiment according to FIG. 1, and therefore extends from the mouth-side end 2 to the strand-side end 3 of the filter cigarillo 1. The area of the cover sheet 12 in the vicinity the strand-side end 3 is not shown in FIG.

Apart from the fact that the cover sheet 12 also covers the filter pad 10 and so far considered, the Filtercigaril- Io 1 is manufactured in a usual manner for filter cigarillos and with customary materials, as known in the art. In addition, the Filtercigarillo 1 a banderole-like mark, which is designed as a band 14 in the embodiment. The band 14 is located in the mouth-side half of the filter cigarillo 1 and is arranged in the embodiment in the vicinity of the filter 8. In the exemplary embodiment, the band 14 is made of paper, extends over the entire circumference of the filter cigarillo 1 and is glued to the cover sheet 12 over the entire surface. In this case, overlap the two ends of the band 14 something (about 2 mm to 4 mm). Embodiments in which a gap remains between the two ends of the band are also conceivable. The adhesive used is an adhesive approved for tobacco products.

The band 14 is printed in the exemplary embodiment with a beautifully designed originality reference. For printing, for example, a paper roll of the width of several individual Banderoles 14 unwound, provided in the gravure printing with the Banderolenaufdruck and rewound and then cut like a disk, so that several endless rollers with successively arranged bands 14 arise. In the manufacture of the filter cigarillo, the first banderole can then be fed from a banderole roll to a respective filter cigarillo 1, and the banderole 14 is separated from the banderole roll and wound around the filter cigarillo 1 after application of adhesive at the location provided for this purpose and with the cover sheet Glued 12.

The Filtercigarillo 1 has in the embodiment has a total length of 84 mm. The filter 8 has a length of 7 mm and the band 14 has a width of 8 mm. The free zone between the mouth-side end 2 of the filter cigarillos 1 and the beginning of the band 14 has a length of about 18 mm in the embodiment. In this zone there is further provided a ventilation zone which extends in the form of a single line of laser perforations at a distance of 13 mm from the mouth-side end 2 around the circumference of the filter cigarillo 1. The total tobacco mass (ie the mass of tobacco 4 plus the masses of leaf 6 and topsheet 12) is just over 1.2 g.
