A tobacco cut filler according to any one of the previous claims, whereby the first tobacco materials is a reconstituted tobacco sheet. Preferably, the minimize filler has a filling power of no less than about three.5 cubic centimetres per gram at a reference moisture value of 12.5 p.c oven volatiles. More ideally, the cut filler has a filling energy of no less than about four cubic centimetres per gram at a reference moisture worth of 12.5 % oven volatiles. In addition, or as an alternative, the reduce filler ideally has a filling energy of lower than about eight cubic centimetres per gram at a reference moisture value of 12.5 percent oven volatiles.
Should one such particle break at a location within the central V-shaped portion, the two resulting elements of the particles would still be successfully V-shaped. The highest CCV values had been obtained for reduce specification no. 3, which substantially corresponds to particles having a Y-shape. However, it was found that when particles were produced from the same sheet of reconstituted tobacco according to minimize specification no. three are produced, a significant fraction of the tobacco materials went to waste. These correspond to the shapes illustrated in Figures 9 and 10, respectively, for which the values of CCV listed in the following Table 3 had been measured. Tobacco reduce fillers based on the present invention may be ready by a way comprising providing a primary tobacco material and cutting the first tobacco materials in accordance with a primary reduce specification setting no less than predetermined first minimize width and first reduce length. Tobacco cut filler in accordance with the current invention could additionally be included into quite lots of smoking articles.
By distinction, in a multimodal distribution, the probability mass operate has a number of maxima, which implies that among the many reduce strips of the first tobacco materials there are multiple values of cut length that occur most often. In the context of the current specification, a distribution having multiple local maxima is thought to be multimodal. It shall be appreciated that the completely different modes in a multimodal distribution can also have totally different frequencies, such that, among the minimize strips of the first tobacco materials, one modal worth of reduce length will happen more frequently than another modal worth.
More ideally, the first tobacco materials is shredded into strips having a reduce width of no much less than about zero.25 mm. Even more ideally, the first tobacco materials is shredded into strips having a minimize width of at least about 0.3 mm. In addition, or as an alternative, the primary tobacco materials is preferably shredded into strips having a cut width of less than about 1 mm.
Suitable natural tobacco leaf supplies include tobacco lamina, tobacco stem material and tobacco stalk material. The natural tobacco leaf material used because the second tobacco material could include any sort of tobacco leaf, including for instance Virginia tobacco leaf, Burley tobacco leaf, Oriental tobacco leaf, flue-cured tobacco leaf, or a combination thereof. A tobacco minimize filler based on the current invention comprises a primary tobacco material minimize in accordance with a first Fashion tobacco pipe reduce specification, whereby the primary cut specification sets no less than predetermined first reduce width and first minimize length. The time period “filling energy” is used to describe the quantity of area taken up by a given weight or mass of a tobacco materials. The higher the filling energy of a tobacco material, the lower the load of the fabric required to fill a tobacco rod of ordinary dimensions.
Even more ideally, first tobacco material is shredded into strips having a reduce length of a minimum of about 15 mm. In addition, or instead, the first tobacco materials is ideally shredded into strips having a cut size of less than about 60 mm. More preferably, the first tobacco material is shredded into strips having a minimize size of lower than about 50 mm. Even more preferably, the first tobacco materials is shredded into strips having a minimize length of lower than about forty mm. In most well-liked embodiments, the first tobacco material is shredded into strips having a minimize length from about 5 mm to about 60 mm. The term “sectional minimize width” is used within the current specification to explain the side- to-side width of 1 such portion of a cut strip of tobacco materials.
In most popular embodiments, the first tobacco material is shredded into strips from a sheet materials having a thickness from about 0.05 mm to about 1 mm. Even more ideally, the first tobacco material is shredded into strips from a sheet materials having a thickness from about 0.1 mm to about zero.3 mm, most preferably from a sheet material having a thickness of about zero.2 mm. A tobacco cut filler in accordance with any considered one of claims 1 to 9, whereby the primary tobacco material is shredded into strips each comprising no much less than a first strip structure comprising a branching node from which an extra strip structure branches off, forming an angle with the primary strip construction. Figures 10 and 12 show two examples of cut strips including a quantity of V-shaped structure. Each V construction contains two substantially straight parts forming an angle.
The yield of flat rolled stem which can be used immediately as filler is increased, and the typical stem length and thus the typical length of cut filler from stem is increased. A tobacco cut filler based on any one of the previous claims having a filling power of no much less than three.5 cubic centimetres per gram at a reference moisture value of 12.5 % oven volatiles. Accordingly, tobacco particles have been prepared from the identical sheet of reconstituted tobacco according to the cut specification illustrated in Figure 12, wherein the cut width SCW1 is of 0.9 millimetres, the minimize size CL1 is of 4.94 millimetres and the worldwide width CW1 is of 12.50 millimetres.
In addition, a second couple of blends was used, that contained 70 p.c by weight of pure tobacco particles and 30 % by weight of reconstituted tobacco particles reduce in accordance with the specifications of Figures 1 1 and 12, respectively. Thus, the minimize width of an individual reduce strip is taken on the level along the length of the strip that yields the most important cross-sectional area. Further, the filling energy of the shredded first tobacco materials can be maximised by deciding on an acceptable first reduce specification. This leads to an improved filling energy of the cut filler as a complete, notably when the primary tobacco material is mixed with a minimum of another tobacco materials.
Experiments had been carried out to find a way to assess the influence of various shapes and cut specifications to key parameters of tobacco cut filler particles, such because the filling energy. In more detail, Figure 1 shows a zigzag-shaped strip and Figure 2 reveals a wave-shaped strip. Where the cut strip is zigzag-shaped or wave- formed, it is possible to measure a wave size of the cut strip, which considerably corresponds to the strip minimize length divided by the variety of repetitions of the zigzag or wave. For occasion, within the cut strip of Figure 1 the zigzag is repeated 10 instances. Preferably, a wave size of the sinusoidal shape is from about 1 mm to about 15 mm, more ideally from about 2 mm to about 12 mm, much more ideally from 4 mm to 10 mm. Preferably, the tobacco cut filler additional comprises a second tobacco materials reduce in accordance with a second minimize specification differing from the primary reduce specification for at least one of cut size and cut width.
