Definitions
- the present application relates to a recess filter, a rod made of several of these recess filters and a smokable object, in particular a cigarette or a cigarillo, with such a recess filter.
- Recess filter or hollow mouthpiece cigarettes have been known for a long time.
- One type of these cigarettes such as papyrossis, has a completely hollow mouthpiece that is often compressed or twisted before or during use.
- one or more filter elements are provided on the tobacco end of the mouthpiece.
- the cavity wall has perforations for the inlet of ambient air and is designed so that it can be compressed in the longitudinal direction after use, thereby reducing the waste ⁇ 'olume - gladly.
- the cavity wall is constructed, for example, in a spiral.
- WO 00/00047 discloses an example of a ventilated recess filter cigarette.
- the airtight cavity wall surrounds the entire filter mouthpiece, i.e. the cavity and the filter elements. Ventilation is achieved by using a mechanically perforated cavity wall, which is also surrounded by a perforated covering sheet. In order to achieve high perforation of up to over 90%, additional perforations are made through the covering paper, the cavity wall and the filter wrapping during the cigarette production by an on-line laser.
- WO 00/00047 therefore describes two of the three methods currently used to produce ventilated recess filter cigarettes. Firstly, the on-line laser perforation. However, this has the disadvantage that it is very expensive because special equipment for the production has to be purchased and this equipment additionally requires special safety precautions. In addition, the on-line laser perforation can only achieve a maximum degree of ventilation of approx. 65%.
- the second method is to perforate the cavity wall material mechanically, for example by needles, before the cigarette is made. This creates relatively large holes.
- This perforated material is then combined with a conventional covering paper which has also been perforated beforehand, ie with a covering paper with relatively small holes.
- the overlying perforated layers cannot be glued together and are therefore extremely easy to to move towards each other. The consequence of this is that the relatively small holes in the covering paper and the relatively large holes in the cavity wall are not always completely or partially superimposed. This results in a relatively large variation and irregularity of ventilation.
- only a maximum degree of ventilation of approximately 50 to 55% can be achieved even with mechanical perforation, since the perforation holes cannot be arbitrarily large in order to maintain the stability of the cavity wall.
- the third current method is to use an air-permeable cavity wall per se.
- the necessary perforation of the cavity wall to achieve ventilation is then omitted here.
- these air-permeable cavity wall materials are very expensive and, under the influence of moisture, such as, for example, from the flow of smoke or the lips of the smoker, the stability is greatly reduced and the cavity can undesirably be pressed in or collapse during use.
- the solution to this problem is a smokable object, in particular a cigarette and a cigarillo, with a tobacco column, which is surrounded with cigarette paper and / or one or more tobacco foils, and - with a ventilated recess filter, whereby the tobacco column and recess filter are connected to one another by an at least partially air-permeable topping sheet, and wherein the recess filter has one or more (preferably successive) filter elements at the tobacco end of the recess filter and a tubular cavity at the mouth end of the recess filter, preferably each filter element is surrounded by a filter covering and the cavity is surrounded by a (tubular) cavity wall, characterized in that that the preferably present filter casing of at least one filter element is at least partially air-permeable, - the recess filter has a degree of ventilation of at least 10%, the cavity wall preferably has a porosity of 100 Coresta units or whom iger and has no perforations, - the cavity wall only surrounds the cavity or incomplete
- a recess filter for a smokable object with one or more filter elements at a first end of the recess filter, with a tubular cavity at the second end of the recess filter, preferably with a filter sheath that surrounds each filter element, and - with a (tubular) cavity wall that surrounds the cavity, characterized in that the preferably present filter sheath of at least one filter element is at least partially air-permeable, which Recess filter has a degree of ventilation of at least 10%, the cavity wall preferably a porosity of 100
- the cavity wall only surrounds the cavity or incompletely and preferably surrounds the cavity and the filter element or elements such that at least at the first end of the recess filter a filter element is at least partially not surrounded by the cavity wall, the cavity wall and the filter element (s) with their preferably present filter coverings are surrounded by an at least partially air-permeable, connecting cover, - the length of the cavity is 10 mm or less and the ratio of the length of the cavity to the total length of the recess filter (including the length of the cavity) 0 , 3 or less.
- the usual materials such as white, cork, gold or aluminum paper, imitation cork paper, straw, silk or rose petals can be used for the covering sheet.
- the topping sheets used are at least partially perforated from their production and therefore have sufficient air permeability to provide the desired ventilation of the filter.
- the usual materials for tobacco, cigarette paper and tobacco foil can be used. For example, any tobacco mixtures can be used.
- the filter elements used preferably have a conventional filter covering. This can be made of paper that has a natural porosity, so that sufficient air permeability is ensured. However, a non-porous filter casing can also be used. However, since ambient air is to enter the filter element (s) from the outside, it is important that the preferably present filter casing of at least one filter element is at least partially sufficiently permeable to air so that e.g. in places where the filter element with the air-permeable filter covering is not surrounded on the outside by the preferably air-impermeable cavity wall, sufficient ambient air can enter the filter sideways.
- the filter elements have a circular or oval cross section, i.e. they are circular or elliptical-cylindrical.
- All customary filter materials can be used as the filter element, for example fibrous, e.g. Cotton, paper, crepe paper, cellulose, acetate fibers, plastic fibers (e.g. made of polypropylene) or cellulose acetate, or granular, e.g. Silica gel preparations, water-containing double silicates, active clay or activated carbon, all of which may contain flavorings.
- fibrous e.g. Cotton, paper, crepe paper, cellulose, acetate fibers, plastic fibers (e.g. made of polypropylene) or cellulose acetate
- plastic fibers e.g. made of polypropylene
- cellulose acetate e.g. made of polypropylene
- granular e.g. Silica gel preparations, water-containing double silicates, active clay or activated carbon, all of which may contain flavorings.
- Silica gel preparations e.g. Silica gel preparations, water-containing double silicates, active clay or activated
- One or more filter elements can be used.
- the use of several, eg two, filter elements is advantageous if the lowest possible condensate values are to be obtained or granular filter elements are to be used.
- Any known filter constructions can be used, ie for example double or triple filters.
- Double filters can, for example, consist of a filter element of cellulose acetate, followed by a paper element or an element with activated carbon.
- Triple filters can, for example, consist of a filter element made of cellulose acetate on the mouthpiece, followed by an element with activated carbon, which in turn is followed by an acetate filter element.
- a possible combination would also be a filter with a hollow chamber in the middle, ie filter element-hollow chamber filter element.
- Suitable materials for the cavity wall are, for example, paper, cardboard or plastic, which is preferably biodegradable.
- the cavity wall must be of sufficient thickness to ensure stability during smoking.
- paper with a basis weight of> 80 g / m 2 , in particular 90-120 g / m 2 and particularly preferably about 110 g / m 2 , and a thickness of> 80 ⁇ m, in particular 100-140 ⁇ m and particularly preferably approximately 125 ⁇ m.
- Such paper can be made up of the usual constituents (for example kraft pulp (approximately 87.5% by weight), inorganic filler (approx. 5% by weight), starch (approx. 0.5% by weight) and moisture (approx. 7% by weight)).
- the cavity of the smokable object or the recess filter should be a maximum of 10 mm and is preferably only 6 mm long or even shorter.
- the cavity is preferably 4 to 6 mm long with a total length of the recess filter of generally 20 to 40 mm and in particular of 25 mm to 31.5 mm.
- the cavity wall is preferably impermeable to air, ie it has an air permeability (or permeability) of 100 Coresta units or less, preferably 10 Coresta units or less, very particularly preferably about 0 Coresta units. Ambient air can therefore penetrate into the filter from the outside through the pre-perforated covering sheet and the preferably present connecting covering and filter covering at the points not enclosed by the cavity wall. pedal and provide the necessary ventilation.
- the cavity wall can also be air-permeable or perforated per se. However, this is not preferred since such measures generally increase the material price and make production more complicated, and additional perforations or air permeability downstream of the vacancies, which are preferably located at the tobacco-side end of the filter, are meaningless for practical use.
- the diameter of the smokable product is 7.6 to 8.4 mm for a normal cigarette and 5.0 to 7.6 mm for a thin or slim cigarette.
- the degree of ventilation can be set as required depending on the permeability of the filter coverings, the connecting coverings and the covering paper. It should be at least 10% (this corresponds approximately to a condensate content of a cigarette of 12 to 14 mg), but better at least 40% (corresponding to a condensate content of approximately 6 to 8 mg), preferably at least 60% (corresponding to a condensate content of ⁇ approximately 4 mg) and very particularly preferably of at least 75% (corresponding to a condensate content of approximately 1 to 2 mg).
- ventilation levels of 90% and more, for example 95%, with a condensate content of ⁇ about 1 mg can also be achieved with the products according to the invention.
- the cavity wall only surrounds the cavity itself or the cavity and part of the filter element or elements.
- the cavity wall next to the cavity itself also surround the mouth-side filter element, but not or only partially the tobacco-side.
- the cavity wall surrounds the cavity itself and the tobacco-side filter element, but not the mouth-side filter element located in between.
- the cavity and the mouth-side filter element can be surrounded by the cavity wall, but not the middle and the tobacco-side filter element.
- the cavity wall comprises the mouth-side and the middle filter element.
- the filter covering, if any, the connecting covering, if any, and the outer covering paper must be at least partially air-permeable, ie an air permeability of more than 100 Coresta units, better of 200 Coresta units or more, in particular 1000 Coresta units or more, preferably have from 10,000 to 20,000 Coresta units or more (for example up to 30,000) and in particular about 12,000 Coresta units.
- the degree of air permeability depends on the desired degree of ventilation.
- the different envelopes do not have to have the same air permeability, however the lowest air permeability of the different envelopes will determine the degree of ventilation.
- the usual materials can be used, which are either naturally porous to achieve the necessary air permeability (such as conventional paper filter wrappings) or can be perforated before use, such as topping sheets Laser or electric spark.
- the necessary perforation or porosity can be provided over the entire surface of the wrappings; however, it is only necessary that adequate ventilation is provided at locations where the filter element or elements are not surrounded by the preferably air-impermeable cavity wall.
- both filter elements are surrounded by an air-permeable filter covering.
- one of the two filter elements can be surrounded with an air-permeable covering, the other, however, with a non-air-permeable, ie with a filter covering with an air permeability of 100 Coresta units or less.
- a filter element (or two or more filter elements) can optionally be provided with an air-permeable filter covering.
- This filter (with or without filter cover) can then in turn be combined with the tubular cavity wall by wrapping it in the connecting cover, so that a recess filter is obtained.
- This recess filter can then be connected in a conventional manner to the tobacco column, which is manufactured separately and wrapped in cigarette paper or tobacco foil, on a filter attachment machine with a pre-perforated covering sheet.
- the use of the connecting covering is not absolutely necessary.
- the filter element, possibly wrapped with the filter covering can also be connected directly on the filter attachment machine to the tubular cavity wall at one end and the tobacco column at the other end via a covering sheet.
- two or more filter elements for example the combination of an acetate filter with an activated carbon filter
- two different production methods are possible both lead to an identical product and both can be carried out continuously.
- a strand of first filter plugs is first produced in the tubular cavity wall.
- the filter plugs have twice the length of the first (mouth-side) filter elements of the finished recess filter and are arranged at a distance from one another which corresponds to twice the length of the cavity.
- This strand is now cut in the middle of the filter plugs and the pieces obtained are combined with second filter plugs twice the length of the second (tobacco-side) filter element in the finished recess filter by wrapping them in the connecting casing.
- the strand thus obtained is then cut in the middle of each second second filter plug, so that a recess filter rod with four times the length of the finished recess filter is produced. (Alternatively, every third second filter plug can be cut in the middle. This results in a recess filter rod six times the length of the finished recess filter.)
- This intermediate product is obtained in the second manufacturing process by fixing, for example glued, cavity walls in an open form onto the non-closed, connecting sheath. A distance between two cavity walls is maintained which corresponds to twice the length of the tobacco-side filter element in the finished recess filter.
- a filter plug is applied between each of the open cavity walls and a filter element, which corresponds to the mouth-side filter element in the finished recess filter, is then applied to the cavity walls.
- the cavity walls and the connecting covering are then closed (for example glued) and the resulting strand is cut in the middle of every second filter plug, which in turn produces the recess filter rod.
- the recess filter rod obtained by one of the two methods described above is cut in the middle on a filter attachment machine, so that two smaller rods are formed, each containing two finished recess filters, with the sequence tobacco-side filter element, mouth-side filter element, cavity (with twice the length of the cavity of the finished recess filter ), mouth-side filter element and tobacco-side filter element.
- These small recess filter rods made of two recess filters are now connected to the tobacco column at both ends of the filter attachment machine with a topping paper and the resulting product is then cut again in the middle so that the finished cigarette is produced.
- FIG. 1 shows a cross section through a recess filter according to the invention with a filter element and part of the adjoining tobacco column
- FIG. 2 shows a cross section through a recess filter according to the invention with two filter elements and part of the adjoining tobacco column
- FIGS. 4 and 5 show two schematic representations for producing a recess filter rod with four times the length of the finished recess filter and
- Fig. 6 is a schematic representation of the manufacture of a recess filter cigarette.
- FIG. 1 shows a cigarette 10 with a partially shown tobacco column 12 and surrounding cigarette paper 14.
- a recess filter 20 can be seen, which is connected to the tobacco column 12 via a topping sheet 16.
- the recess filter 20 has only a single filter element 22 made of acetate, which is surrounded by an air-permeable filter covering 28.
- the filter element 22 is through the connecting sheath 34 connected to the air-impermeable cavity wall 32, which in turn surrounds the cavity 26.
- the air-permeable covering paper 16, the air-permeable enveloping connection 34 and the air-permeable filter cover 28 allow ambient air to enter the filter 20 sideways and thus provide the necessary ventilation without causing a large variation.
- FIG. 2 shows an alternative embodiment of the recess filter cigarette 10.
- the tobacco column 12 can again be seen, which is surrounded by cigarette paper 14 and is connected to the recess filter 20 by the covering paper 16.
- the recess filter 20 here has two filter elements, namely a first filter element 22 and a second filter element 24.
- the first filter element 22 is surrounded by an air-impermeable filter sheath 28, the second filter element 24, on the other hand, by an air-permeable filter sheath 30. Both filter elements 22 and 24 are in turn connected to the air-impermeable cavity wall 32 which surrounds the cavity 26 via the connecting sheath 34.
- Fig. 3 shows a further embodiment for a recess filter cigarette 10.
- this embodiment again has two filter elements, namely the first filter element 22 and the second filter element 24.
- the filter casing 28 of the first filter element 22 can be air-permeable or air-impermeable. This does not matter, since the air-impermeable cavity wall 32, which surrounds both the first filter element 22 and the cavity 26 in this embodiment, prevents ambient air from entering the first filter element 22 sideways.
- the filter covering 30 of the second filter element 24 therefore has a high permeability, so that sufficient ventilation is provided via the second filter element 24 when the cigarette 10 is smoking.
- a 10th alternative to the embodiment shown is that the
- Cavity wall 32 does not completely surround the first filter element 22, but only partially.
- Figures 4 to 6 show manufacturing options for a
- first filter plugs 23 which have twice the length of the first (mouth-side) filter elements 22 in the finished recess filter and which are covered by the envelope
- treatment paper 29 (also with twice the length of the wrapping paper 28) are continuously wrapped on a machine in the airtight cavity wall 38.
- one end of the strand can be seen on the left with a filter plug 22 of the correct length.
- the filter plug 23 is cut through in the center.
- the elements thus obtained are wrapped in a second filter plug 25 with their wrapping paper 31 and twice the length of the second filter element 24
- the recess filter rod 40 with first filter elements 22 made of cellulose acetate and second filter elements 24 made of cellulose acetate with activated carbon granules is finally obtained by cutting the strand in the middle of every second filter plug 25.
- the cavity wall 33 is glued onto the open connecting sheath 36.
- the distance between two cavity wall ends corresponds, as can be seen in FIG. 5, to twice the length of the tobacco-side filter element 24 in the finished recess filter.
- the mouth-side filter elements 22, here made of cellulose acetate are glued to the ends of the cavity walls 33 with the paper wrappings 28.
- the filter plug 25, here made of cellulose acetate with activated carbon granulate, with its paper wrapping 31 is glued onto the connecting wrapping 36 between two ends of the cavity wall, and the continuous strand is then closed in the next step.
- the cut is again made in the middle of every second filter plug 25, through which the recess filter rod 40 is obtained.
- the recess filter rod 40 is cut in the middle of the filter plug 25, whereby two smaller products are obtained. These each consist of two recess filters connected via their mouth sides, ie on the outside there is the tobacco-side, second filter element 24, followed by the first, mouth-side filter element 22 and the cavity 27 in the middle, which is twice the length of the cavity 26 in the finished product.
- the first filter elements 22 and the cavity 27 are surrounded by the cavity wall 33 and the entire products by the connecting sheath 36.
- These products are now connected to the tobacco column 12 via the covering paper 16 in the last step of the method, ie glued as usual the filter completely and the beginning area of the tobacco column surrounds. If the product obtained in this way is now cut in the middle, a finished recess filter cigarette is produced, similar to the recess filter cigarette 10 shown in FIG. 3.
- the cavity wall 32 comprising the cavity 26 and the mouth-side filter element 22, but not the tobacco-side 24.
- the cavity wall 32 is made of paper with the manufactured following features. Weight: 110 g / m 2 , thickness: 124 ⁇ m, permeability: 0 Coresta units, tensile strength: 145 N / 15 mm, components: kraft pulp approximately 87.5%, inorganic fillers approximately 5%, thickness approximately 0.5%, Moisture about 7%.
- the mouth or cavity-side filter 22 (filter element 1) consists of cellulose acetate
- Filter element 2 Length (in mm) 15 15 15 15 15 Draw resistance 2 43 43 43 108 Permeability 12000 CU 12000 CU 12000 CU 12000 CU of filter wrapping 1 Cigarette Tobacco American American American American American blend Blend Blend Blend Cigarette paper 34 CU 34 CU 34 CU 34 CU Permeability 1 Permeability 210 CU 700 CU 1650 CU 1650 CU of the base paper 1 (pre-perforated by laser) Length of the base 32 32 32 32 paper (in mm) Cigarette length 84 84 84 84 (in mm) Diameter (in mm) 7.9 7.9 7. 9 7.9 draw resistance 2 115 91 78 88 of the cigarette Degree of ventilation 20 44 60 72 (average in%)
- the recess filter 20 according to the invention can achieve the entire condensate range from approximately 10 mg to 2.0 mg, the ventilation degrees being between 20 and 72%.
- the ventilation can of course be increased even further, which means that even lower condensate values can be obtained.
- a conventional product is compared with a product according to the invention.
- the conventional product is the cigarette with the recess filter according to Example 4 above, but in which the cavity wall 32 surrounds the entire recess filter.
- the ventilation is achieved by mechanical perforation of the paper from which the cavity wall 32 is made and the covering paper.
- the cigarette 10 according to the invention corresponds to the products described above in Examples 1-4, i.e. likewise cigarettes 10 with two filter elements 22, 24 according to Examples 1-3 and for the last experiment in Table 3 according to Example 4, in which, however, the cavity wall 32 only surrounds the cavity 26 and the mouth-side filter element 22.
- the tobacco and filter materials used, the lengths of the filter elements, the total filter and the total cigarette and all other parameters are the same for the two cigarettes compared.
- the permeability of the topping sheet is calculated for the reference product from 720 to 2800 Coresta units (Table 2) and for the cigarettes of the invention varied from 150-1650 Coresta units (Table 3). The results are shown in Tables 2 and 3.
