Definitions

  • the present invention relates to a filter cigarette with a tobacco rod and two different filters attached to the tobacco rod, which can be detached from the tobacco rod, hereinafter referred to as "double filter cigarette”.
  • the invention further relates to a filter covering paper for attaching a filter to a tobacco rod and to the use of a double filter cigarette according to the invention with a cigarette box.
  • the invention shows a method for producing such a double filter cigarette.
  • Filter cigarettes that have multiple filters are known in principle.
  • DE 27 09 777 AI describes a divisible cigarette with separating strips, which can be equipped with two filters at its ends. This is intended to offer the consumer shorter cigarettes with and without a filter, in order to avoid tobacco being wasted if the consumer does not want to smoke a normal long cigarette.
  • GB-A 851.324 also discloses the production of short filter cigarettes, the two cigarettes being connected to one another at their central double filter by means of a separable covering paper, so that two filter cigarettes are produced by breaking open this covering paper.
  • a cigarette with filters at both ends of a tobacco rod is also known, which can be separated in the middle or on a filter in order to produce two shorter cigarettes or one long cigarette.
  • a cigarette which has a tobacco rod surrounded by cigarette paper with filters provided at its ends.
  • the filters In order to smoke the strength of the cigarette individually, it is proposed that the filters have different lengths.
  • a normal filter paper is used for each filter.
  • the disadvantage here is that after removing one of the filters directly on the filter body at the end at which the cigarette is to be lit, a filter paper residue remains which affects the taste when the cigarette is lit. In order to rule out this impairment, the filter would have to be removed at a point where there is no longer any covering paper, which would result in a very irregular or frayed tobacco rod end section. In addition, tobacco is wasted.
  • a suitable filter paper should also be provided.
  • the filter cigarette according to the invention achieves the first-mentioned object in that it provides a filter covering paper for attaching a filter to a tobacco rod, which has a covering paper strip and an adjoining cigarette paper strip, the cigarette paper strip forming the connecting section between the tobacco rod and the filter.
  • a filter covering paper for attaching a filter to a tobacco rod which has a covering paper strip and an adjoining cigarette paper strip, the cigarette paper strip forming the connecting section between the tobacco rod and the filter.
  • each individual filter of the double filter cigarette according to the invention can be designed accordingly.
  • the use of such a special filter paper makes the handling of the cigarette according to the invention by the consumer much more practical.
  • the filter covering paper no longer protrudes beyond the filter onto a part of the tobacco rod, but rather the part which overlaps the tobacco rod, that is to say the connecting section, is formed from cigarette paper.
  • the filter can be cleanly separated at the section where the cigarette paper strip adjoins the topping paper strip without a frayed cigarette end.
  • a configuration is preferably used in which no perforations or other separation aids are provided, since these act as additional ventilation openings and would in turn influence the taste. Overall, however, it cannot, of course, be ruled out that perforated cigarettes or those provided with ventilation openings can also be designed according to the invention.
  • the topping paper strip is formed in one piece together with the cigarette paper strip, the physical properties, in particular the strength, of a topping paper strip being imparted to the topping paper strip.
  • the two filters have a different structure.
  • filters with several chambers connected in series or coaxial filter configurations can be used.
  • Filter materials that are denser or less densely packed can also be used.
  • the desired effect can also be achieved in that the two filters are constructed from different filter materials, for example cellulose acetate or paper filters or activated carbon filters, and / or are provided with different filter ventilation.
  • the two filters are constructed from different filter materials, for example cellulose acetate or paper filters or activated carbon filters, and / or are provided with different filter ventilation.
  • additives e.g. activated carbon
  • the latter can also be achieved by adding a flavor (e.g. in the form of threads or capsules) to one filter or different flavors for both filters.
  • markings are made in the area of the filter, which mark the cigarette formed when a filter is removed.
  • markings are preferably lettering which are printed in the vicinity of the end of the filter on the strand side.
  • the preferred procedure is that when a filter is removed, the corresponding marking or the corresponding lettering is also removed, so that a cigarette remains which has a taste which is configured in accordance with the printing on the remaining filter.
  • the cigarette preferably has a length of 80 to 120 mm, preferably 100 mm, the length of the tobacco rod according to the invention being 40 to 60 mm and preferably being about 50 mm.
  • the cigarette paper strip protrudes over a longitudinal edge of the covering paper strip and can be used in this projecting area for fastening the tobacco rod.
  • This covering paper is preferably formed by a double covering paper made from a central strip of cigarette paper and two strips of covering paper attached to the side, which is separated in the middle, so that two filter covering papers according to the invention are mirror-image to one another.
  • Such "double" covering papers can be processed on modern machines.
  • filter cigarettes of this type can be used with a cigarette box which has opening flaps on both end faces.
  • a cigarette box is particularly preferably used which has opening flaps which are each articulated on opposite flat sides of the box at an end edge.
  • opening flaps which are each articulated on opposite flat sides of the box at an end edge.
  • German patent specification DE 198 09 865 C1 in which such a box is described in detail.
  • FIG. 1 of this above-mentioned patent specification is incorporated herein by reference together with the corresponding explanation. If such a box is used and preferably the opposite flat sides are provided with markings or inscriptions which correspond to those cigarettes which can be removed from the box with the filter ahead from this flat side, it poses no problems for the consumer, simply take the desired cigarette out of the box at the mouth end, where the filter remains on the tobacco rod, and separate the opposite filter end.
  • the invention also shows a method for the manufacturing, i.e. mass production, of a double filter cigarette with a tobacco rod and two filters attached to the tobacco rod with significantly different filter effects, in which a filter is attached to both ends of the prefabricated tobacco rod and by means of a topping paper adapted to the desired specification is connected to the tobacco rod.
  • This method can be implemented on conventional cigarette making and filter attachment machines, which need only be modified slightly, so that the manufacturing of such double filter cigarettes is possible without great additional effort.
  • a so-called “double topping paper” consisting of a central strip of cigarette paper and two strips of covering paper connected to it on its longitudinal edge.
  • This double covering paper is separated in particular by a separating knife into two halves, which are preferably mirror-symmetrical to one another, extended to the corresponding width and then used to fasten the two filters to the central tobacco rod.
  • the two topping strips of this double topping paper are so wide that they cover the individual filters, while the cigarette paper strip has to be so wide that good adhesion to the topping paper as well as to the cigarette paper of the tobacco rod is possible.
  • the two covering papers can have different specifications, which are adapted to the specifications of the filters used, in particular with regard to ventilation, thickness, width and color.
  • covering papers the structure of which is designed in such a way that the part of the covering paper glued to the tobacco rod is thin enough to enable the filter to be easily separated from the tobacco rod.
  • this can be achieved, for example, by a cigarette paper-like base paper which is reinforced in the area of the mouth end / filter by printing.
  • the printing can be done in one stripe (with an unprinted stripe on the edge) or in two stripes (connected by an unprinted stripe), so that topping paper results in the geometries described above.
  • different specifications can be achieved on a "double covering paper" by printing.
  • FIG. 1 shows a double filter cigarette according to the invention with different filters at both ends;
  • FIGS. 2 and 3 the front and back of a special cigarette box for use with the filter cigarettes of the invention
  • FIG. 4 shows filter covering paper according to the invention with a covering paper strip and a cigarette paper strip attached to it;
  • Figure 5 is a schematic representation of the method for producing such a double filter cigarette
  • FIG. 6 shows a double filter covering paper, as can be used in the method.
  • FIG. 7 is a filter covering paper created by cutting the double filter covering paper.
  • FIG. 1 shows a double filter cigarette according to the invention. It consists of a tobacco rod 3, on each of which a filter 1 and 2 is attached. The double filter cigarette is labeled with a total of 10.
  • the two filters differ according to the present invention.
  • the filter 1 is designed such that when the cigarette is smoked with the filter 1, but without the filter 2, a strong cigarette is produced. To do this, filter 2 must of course be removed beforehand.
  • the filter 2 remains on the tobacco rod 3 and the filter 1 is separated off, a lighter cigarette is obtained, namely through the different filter effects in the filters 1 and 2.
  • the filter 2 therefore has a higher retention than the filter 1.
  • the filters 1 and 2 are attached to the tobacco rod 3 on each side with a filter paper 11 according to the invention.
  • a filter covering paper 11 can be rolled out from the inside in FIG. It consists of a topping paper strip 9 to which a cigarette paper strip 8 is glued so that it protrudes on one long side.
  • the filter is now connected to the tobacco rod 3 on this cigarette paper strip 8, and only in the region of this strip (ie not in the region of the topping paper strip 9). This means that when the filter is removed, only part of the cigarette paper strip 8 remains at the free end of the cigarette. When burned, this remainder of the cigarette paper strip 8 does not create an adverse taste impression.
  • the separation at this point also creates a cigarette that is smooth at its end to be burned, that is, not frayed.
  • a print is applied to each of the cigarette paper strips 8, which indicates which cigarette is produced when the opposite filter is removed.
  • FIG. 2 shows the front of this cigarette box, while FIG. 3 shows the back.
  • cigarettes are shown in the position in which they are located in the box.
  • the front side of the box in FIG. 2 is provided with the reference number 5, and the lid which opens from this side bears the reference number 4.
  • the rear side 7 is shown and the other lid 6 of the box opens this back 7.
  • the So the box has a lid on both ends, each opening on opposite flat sides.
  • this box After filling with double filter cigarettes according to the invention, this box allows the consumer to clearly distinguish between two different cigarette versions in a pack and to offer them in an appealing manner.
  • opening the lid 6 of the back 7, for example he receives the lighter version of the cigarette; if he turns the pack and opens the lid 4 of the front 5, he gets the more powerful version, and always when he disconnects the opposite filter.
  • the box is usefully equipped with the emblem of the respective version on the front and back. The consumer can thus respond individually to his current taste needs without having to carry two packs of cigarettes.
  • FIG. 5 schematically shows a method for manufacturing such a double filter cigarette.
  • a conventional cigarette making machine 20 produces tobacco rods 22 with a length of 40 to 60 mm, in particular 50 mm, which are transferred to the relay drum 24 of a filter attachment machine.
  • the tobacco strands 22 are positioned centrally on the relay drum 24 in such a way that a filter can be attached to the two ends of the tobacco strands 22.
  • 24 trough-shaped depressions are provided in the surface of the relay drum, each of which accommodates a single strand of tobacco.
  • Filters with a first filter effect are transferred from a first filter magazine 26 and filters 32 with a second, different filter effect are transferred from the second filter magazine 30 to the relay drum 24 and attached to the tobacco rods 22 held in the troughs of the relay drum 24 from both sides.
  • a so-called "double covering paper” 42 is fed from a bobbin, not shown, which can be seen in detail in FIG.
  • the double topping paper consists of a central strip 44 of cigarette paper, which is connected at its two longitudinal edges to a strip of topping paper 46, 48, respectively. It is therefore a covering paper of the embodiment according to FIG. 4 which is broadened in its mirror image.
  • the two strips 46, 48 of covering paper are so wide that they each cover the assigned filter 28, 32.
  • the strip 44 of cigarette paper is so wide that good bonding is possible both to the two side covering papers 46, 48 and to the cigarette paper of the tobacco rods 22.
  • the strip 44 of cigarette paper should have a width of approximately 4 to 32 mm.
  • the specifications of the two strips 46, 48 of base paper are adapted to the filter specifications of the two filters 28, 32 in terms of ventilation, thickness, width, color, etc.
  • covering paper In addition to this particularly suitable covering paper, however, it is also possible to use all other covering papers which are constructed in such a way that the part of the covering paper glued to the tobacco rod 22 is thin enough to enable the filter to be easily separated from the tobacco rod. This can be achieved, for example, with a base paper similar to cigarette paper, which is reinforced in the area of the mouth end / filter.
  • the double topping paper 42 is separated by a separating knife 50 into two mutually mirror-symmetrical halves, each made from a strip of cigarette paper 52, 54 and the two strips 46, 48 of topping paper, moved apart in a V-shape to the corresponding width of the tobacco rod 22 and to a suction roller 38 with openings for babies Pass 40, which fix the two strips.
