Definitions

• the invention relates to a rod-shaped smoking product with a strand-shaped core made from shredded smoking tobacco, which is surrounded by a jacket made of tobacco foils produced by a paper manufacturing process.
• Such a smoking product is known, for example, from EP-A-0 495 567, the tobacco foil, which is also referred to as a sheet of reconstituted tobacco, having been produced by a paper production process in accordance with US-A-4,182,349.
• stems of the tobacco plant, tobacco ribs and other tobacco components that cannot be used in cigarette production, in particular very fine fractions but also tobacco leaves, are defibrated and mixed or washed out with, for example, heated water or other aqueous liquids of certain temperatures, after which the sieve device is used to filter them the water-containing extract extract is withdrawn;
• the cellulose constituents are optionally repeated after further intermediate stages such as homogenization Sieving or cleaning, together with fillers and other additives, are added to the sieve of a paper production device after further intermediate stages.
• the concentrated tobacco extract is applied to the raw film thus obtained and this is processed into the final tobacco film.
• tobacco foils produced according to such an extract process have so far been used in small chunks for stretching smoking tobacco in cigarettes or cigarillos, primarily using the fines and ribs which are unsuitable for cigarette manufacture as a smokable material.
• tobacco foils of this type were used as cover sheets for cigarillos because of their uniform structure and better mechanical properties.
• tobacco foils as a binder or cover sheet for smoking products is problematic for many reasons, because the tobacco foils are inadequate in terms of sensors due to the tobacco starting material and / or because of the darker color they are not appealing to the consumer. Numerous attempts have been made to overcome these disadvantages, for example by enzymatically processing the extract. Such measures have so far been unsuccessful and have also resulted in products that do not meet legal requirements. In addition, there were considerable difficulties with the required properties of such tobacco films with regard to their tear resistance, their water resistance or saliva resistance or very generally with regard to their smoking properties, such as porosity, burning behavior, ash content and in particular with regard to the smoke aroma familiar from the consumer.
• the tobacco film is obtained essentially from ribs and fine fractions by the extraction paper process, the extract obtained by this paper production process being reduced in order to reduce secondary smoke, only in a limited amount, namely not more than 20% by weight .% (based on the weight of the tobacco foil) should be applied again.
• the taste quality or aroma of such a product leaves something to be desired.
• the invention is based on the object of proposing a novel smoking product of the type mentioned at the outset which once satisfies the typical flavor expected by the smoker, which until now could not be achieved by tobacco wrapped smoke products, and which on the other hand improves the quality of the secondary smoke.
• a smoke product encased in this way is proposed, in which the casing formed from tobacco foils is designed with regard to the physical characteristics of the foil so that the smoke product can be produced economically on conventional cigarette or cigarillo production systems and thus meet the requirements with regard to tensile strength and elongation such jacket production fulfilled, with the glow rate and porosity allow control of the smoke supply.
• a smoking product which is designed according to the main claim, particularly preferred embodiments being set out in the subclaims.
• the use of smoking products as novel plug-in cigarillos is also proposed.
• the tobacco foils for the cover sheet ie the outer wrapping of the rod-shaped smoke product
• the tobacco wrapper of the topsheet is fed or returned considerably more tobacco extract than the binder.
• tobacco foil In total, the jacket of the rod-shaped smoking product consisting of two layers contains a tobacco extract amount of more than 20% by weight, based on the dry substance.
• the tobacco film produced by the paper manufacturing process according to TF-1 consists of 75 to 100% by weight essentially of (a) tobacco cellulose and (b) tobacco extract consisting of tobacco components.
• the tobacco cellulose is obtained from a shredded leaf or cut tobacco mixture, from tobacco greens (scrap), from tobacco stems and from tobacco stem material, the aroma-intensive components, namely the leaf tobacco mixture and the tobacco greens having a particle size of about 1 to 5 and preferably 1 , 5 to 4 mm on the one hand and the components which are more determining for the cellulose content, namely tobacco rib material on the other hand, are present in a weight ratio of 1: 1.1 to 1: 5.
• the tobacco extract is made from a shredded leaf or cut tobacco mixture and received tobacco rib material.
• the tobacco films up to 20% by weight and preferably 8 to 14% by weight of foreign cellulose such as softwood, hemp or flax cellulose are used to produce the tobacco films. If the tobacco cellulose comes wholly or partly from tobacco stalks, the proportion of foreign cellulose can be reduced accordingly without impairing the physical properties of the tobacco film.
• foreign cellulose such as softwood, hemp or flax cellulose
• the tobacco material required to produce the tobacco foil consists of a high-quality cut tobacco mixture, for example a mixture of Virginia tobacco, Burley tobacco, Orient tobacco and blowing ribs from Virginia -Tobacco exists.
• the proportion of tobacco rib material required to produce the tobacco film is somewhat higher, which is necessary in view of the physical properties of the tobacco cellulose.
• the ratio of leaf or cut tobacco mixture to tobacco stem or tobacco stem material should not exceed a value of 1: 5, since otherwise the flavor-determined smoking properties of the tobacco foil are adversely affected. If necessary, however, this can be compensated for by adding tobacco flavors during the last step of the film production process.
• the extract is applied to the cellulose material obtained in this process in an amount of more than 20% by weight of the tobacco foil. If the extract contains an increased proportion of a lamina tobacco extract, the aroma components required for the final smoking product are enriched.
• This tobacco film manufactured according to another paper manufacturing process consists essentially of lamina tobacco material with regard to its tobacco content. Based on the tobacco film, this is crushed in an amount of 75 to 80% by weight together with 10 to 20% by weight of long-fiber foreign cellulose and, when the cold-water-soluble tobacco extracts are almost completely circulated in the wire section of a paper production plant, is obtained as raw film on this.
• the usual additives that are still required, such as binders, fillers and the agents influencing the burn-off, as well as flavorings, can be added in an amount of up to 15% by weight both when the raw film is produced and later when it is conditioned.
• the tobacco film in its taste-relevant tobacco mixture composition corresponds to the composition of the leaf or cut tobacco mixture of the tobacco inlay or the core of the rod-shaped smoking product. This is on the one hand, to achieve the desired taste - preferably "American blend" - necessary, on the other hand, with regard to a simple, inexpensive manufacture of the rod-shaped smoke product, an advantage overall, since both the casing and the core can be produced with the same tobacco mixture.
• the tobacco mixture composition of the tobacco film can be changed from the mixture composition of the tobacco.
• binders such as methyl cellulose, dextrins, pectins, alginates, starch, gums, amylose, carboxymethyl cellulose, honey, corn syrup or other polysaccharides can be used as additives.
• Calcium carbonate or titanium dioxide for example, can be used as filler.
• Flavorings that can be used later are tobacco flavors or extracts from tobacco mixtures, for example by an on-line loading of the tobacco foils, which are manufactured per se, by means of the loading device from Kaymich (GB) (Kaymich applicator model FDU3 SYSM).
• the flavoring is preferably carried out in alcoholic solution, preferably on the inside of the tobacco foils, in order to avoid undesirable optical effects, over the entire surface or in longitudinal strips.
