Definitions

• the invention relates to a product made from tobacco or tobacco leaves.
• the invention further relates to a method of making such product.
• a cigar is made from a core consisting of stripped, cut and/or folded tobacco leaves, which core is held together by tabacco wrapper leaf wound around it.
• the core is the essential constituent, with the stripped, cut and/or folded tobacco leaves being held together in such a way that a great multiplicity of fine air passages extending in the longitudinal direction of the core are formed and maintained.
• This last is the main purpose of the tobacco wrapper which ensures that the core is held together in the desired manner and the fine air passages are closed off relative to the surroundings in radial direction of the core.
• Another type of tobacco product is chewing tobacco.
• the tobacco leaves are processed and compressed to form a piece of material whose appearance can be designed in various manners.
• the most commonly used forms are blocks and rods.
• this is achieved with a product made from at least one tobacco wrapper which is tightly and helically wound directly around a substantially open core extending throughout the length of the product.
• a product so obtained can be consumed in the same manner as a thin cigar, while it is equally possible to consume the product by chewing it because of the fairly solid, tightly-wrapped cover in combination with the subtantially open core which can easily be bitten or pressed shut.
• the substantially open core can be realized and designed in many ways. Because it should also be possible to smoke the product, the open core should be so dimensioned that the smoke sucked from the open core is not too hot. In view of this, it is preferable, in accordance with a further embodiment of the invention, that the core is a substantially cylindrical passage, whereby in relatively simple manner optimum conditions have been created to keep the speed and temperature of the smoke sucked through the open core within a desired range.
• flavourings are incorporated into the product, which can be drawn from the product along with the air sucked through the open core, an extra dimension has been added to the consumption of the product in that this enables consumption of the product not only by chewing and smoking but also by sucking the product, which yields a particular taste in the mouth, naturally depending on the selected flavouring, which can be chosen from a wide range of known flavourings.
• flavourings that can be drawn from the product by chewing it.
• these flavourings can be combined with flavourings that can be released from the product by sucking or smoking.
• the invention further relates to a method of making a product from tobacco leaf, which method is characterized by winding at least one tobacco wrapper tightly and helically around a mandrel, the dimensions of each tobacco wrapper and the pitch angle of the helical wrapping being selected such that a first winding is at least partly covered by at least a second and a third winding and each tobacco wrapper being processed so that upon completion of the winding operation the tightly wrapped configuration is maintained even during and after the removal of the mandrel so as to obtain a substantially open core.
• the product by wrapping at least one tobacco wrapper tightly and helically about a mandrel of substantially open cross-section, the dimensions of each tobacco wrapper and the pitch angle of the helical wrapping being selected such that a first winding is covered at least partly by at least a second and a third winding and each tobacco wrapper being processed so that upon completion of the winding operation the tightly wrapped configuration is maintained, with the mandrel remaining behind in the product as a lost core.
• a new tobacco product can be obtained, having a solid cover surrounding a substantially open core, which product can be consumed both by smoking and by chewing or a combination of the two.
• an elongated rod-shaped member is used, which in the case of a mandrel that is to be removed afterwards can be a wire of varying or constant circular cross-section.
• flavourings are incorporated into the product, which can be effected in different manners.
• flavourings which are to be released by means of smoking or chewing
• the substantially open core makes it possible to draw the flavourings from the product by sucking air through that core. In that case, it may be preferable for flavourings to be provided in the open core after winding of the tobacco wrapper.
• any combination of the above described methods depending on the manner or manners of consumption contemplated.
• flavourings in the open core or in or on the surrounding parts of the solid cover can be effected by means of injection or impregnation, but can also be realized by providing flavourings on the mandrel prior to winding. If a mandrel that is to be removed from the winding is used, this can be realized in relatively simple manner by preparing the flavourings and the tobacco wrapper wound around the mandrel in such a way that the flavourings remain behind in the product.
• flavourings can also be effected by means of a combination of the method using a retractable mandrel and a method using a lost core, when, in accordance with a further embodiment of the invention, the flavourings are provided on a lost core which remains behind in the product upon removal of the mandrel therefrom.
• a lost core may for instance be made from a cellulose fibre which has been impregnated and/or treated with flavourings, with the cellulose fibre being given any appropriate form and treatment so as to effect the desired release of the flavourings in optimum manner during chewing, smoking as well as sucking.
• a first winding must be covered at least partly by at least two further windings. This is necessary, on the one hand, to obtain a sufficiently solid cover for maintaining the core passage and, on the other hand, to obtain a sufficiently thick cover to permit handling of the product.
• Such a product can be wound from an elongated strip-shaped cut tobacco wrapper having a parallellogram-shaped circumference, with the angle between two adjacent sides corresponding with the pitch angle of the helical winding for manufacturing the product. If the product is prepared from such a tobacco wrapper, a substantially cylindrical body with circular end faces is obtained.
• the length of the mandrel is chosen to be a multiple of the length of the product and that after the winding operation and, depending on the type of mandrel used, removal of the mandrel, the intermediate so obtained is cut to form products of the desired length. After winding the wrapper onto this relatively long mandrel and, depending on the type used, removing the mandrel, the product thereby obtained is cut into pieces having the desired length, with the two terminal ends, if so desired, being regarded as waste, so that in principle any shape of tobacco wrapper can be used.
• both ends of the products according to the invention can be straight end faces, i.e. neither end needs to be of tapering or similar configuration owing to the solid cover and the substantially open core, although such a configuration of the ends is possible.
• a lost core may be made from a cellulose fibre which can be used up in the same way as a tobacco wrapper through smoking or chewing.
• the core can also be made from a material that is not used up.
• a removable mandrel can for instance be a solid steel wire.
• flavourings are supplied in capsules, so that a product can be provided with the desired flavouring or flavourings for consumption.
