Definitions
- the present invention relates to biodegradable dual density filter cigarette.
- biodegradable dual density filter cigarette comprising of two portions, a tobacco rod and butt portion joined to each other longitudinally.
- the embodiment of the invention resides in the cost effective process of manufacturing the dual density cigarettes and subsequent product such as high density cigarettes, plugs and other combinations.
- the non-filter cigarettes have tobacco with normal density throughout the length of the cigarette. Often the loose tobacco particles enter the mouth of the smoker due to the absence of a filter. The Non-filter cigarette often turns soggy at the smoking end due to constant contact with the smoker's mouth. Besides, due to the relatively loose packing density of the tobacco and loss of tobacco particles from the nonsmoking end, the cigarette loses its stiffness.
- Filter cigarettes contain tobacco of normal density along with synthetic filters.
- the filter plug in a filter cigarette comprises of fibrous material attached to a normal density tobacco rod.
- the fibrous material can be cellulose, acetate tow, polypropylene tow, or any of the other known kind of synthetic fibrous material.
- U.S. patent application Ser. No 09/988,828 teaches about a filter cigarette with tobacco filter in which the tobacco strand enclosed by a cigarette paper.
- the tobacco used is manufactured without using medium cut roll stem and without reconstituted tobacco with a width cut of 0.3 to 0.6 mm and the filter has a tobacco packing density of 350 to 400 g/cm 3 .
- EP 1250 854 A1 describes a poison-reduced cigarette includes adding hydrate of double salt of ferroso-ferric chloride into tobacco and cigarette filter to react with nicotine to form salt which will not be absorbed by the mucous membranes in the smoker's respiratory system for minimizing nicotine poison and for enhancing the smoker's health.
- EP 1032282 describes a filter for tobacco products, in particular cigarettes, is made of a cellulose nonwoven fabric produced by an air-laid process and spirally rolled.
- EP 1032283 describes a filter cigarette comprising a biodegradable filter and a tobacco strand surrounded by cigarette paper, a non-woven air-aid cellulose filter with a normal retention capacity and a filter ventilation area extending in a peripheral direction.
- the filter cigarette has the combination of features.
- the filter has a condensate retention capacity of 40-60%; the non-woven cellulose is non-crimped, the nicotine/tobacco strand condensate yield ratio lies between 0,6 and 0,9 (nicotine *10/condensate), the apparent density of the tobacco mixture of the tobacco strand ranges from 200 to 250 mg/ml, the tobacco strand drag is between 45 and 65 mmw WS when measured in an enclosed form, air permeability of the cigarette paper is 20-50 CORESTA units and the filter ventilation degree is 15-50%.
- WO 01/58290 A1 discloses a cigarette filter for easily removing harmful materials like nicotine and tar from cigarette smoke.
- the filter can filter harmful ingredients such as nicotine and tar included in cigarette smoke, through a front filter, a mugwort-impregnated filtering-net, a diffusing body, a pine resin-impregnated filtering-net and then a back filter.
- the filter which incorporates the mugwort and the pine resin therein thus is helpful in preserving the health of the smoker, as well as allowing the smoker to feel normal during inhalation, which results from the aromatic properties of the mugwort and the pine resin impregnated into filtering-nets present within the filter.
- the filters of cigarettes designed to filter harmful materials, such as nicotine and tar, are provided at one end of the cigarette.
- Such filters are typically classified into several types as follows: That is, the conventional filters of the cigarettes are classified according to their structure into a single filter consisting of one integrated filter, a double filter formed by a linear arrangement of two filter segments, and a multiple filter formed by the linear arrangement of a plurality of different kinds of filter segments.
- the filters are also classified according to the material of the filters into a fiber filter, a chemical granule-laden filter, and a carbon granule-laden filter.
- fiber filters allow hazardous materials included in the cigarette smoke to simply pass through their fibrous matrix, and thus a large effect cannot ba expected.
- fiber filters, particularly those laden with carbon or chemical granules for removing nicotine and tar have been most preferably and widely used as filters for cigarettes.
- a cigarette rod making machine employs a distributor which delivers fragmentized particles of tobacco leaves, fragmentized sheets of reconstituted tobacco and/or fragments of artificial tobacco to a stream building zone wherein the particles from a continuous stream.
- a distributor which delivers fragmentized particles of tobacco leaves, fragmentized sheets of reconstituted tobacco and/or fragments of artificial tobacco to a stream building zone wherein the particles from a continuous stream.
- Such stream contains surplus of fibrous material and is converted into a continuous rod during travel with a conveyor past a trimming or equalizing device which removes the surplus.
- the resulting rod also called filler
- the resulting rod is thereupon condensed and draped into a web of cigarette paper or other suitable wrapping material to form with the web a cigarette rod which is subdivided (e.g., by a conventional cutoff) into sections of unit length or multiple unit length.
- the object of the present invention is to provide the smoker a filter cigarette having a filter portion which is biodegradable that substantially reduces the tar and nicotine elements and having higher chloride contents.
- the object of the present invention is to provide the smoker a filter cigarette which is at the same time inexpensive and environment friendly.
- Yet another object of the present invention is to provide a naturally biodegradable cigarette having a smoke delivery profile comparable to the synthetic filter cigarette.
- Another object of the present invention is to provide a cost-effective process of producing dual density tobacco rod and subsequent product usage option such as high-density cigarette, plugs and other combinations.
- Further object of the present invention is to give satisfaction comparable to that of the conventional filter cigarette without actually having synthetic filter in the cigarette.
- the present invention provides a biodegradable, environmental friendly, cost effective filter cigarette with reduced health hazards.
- the present invention relates to a biodegradable dual-density cigarette comprising of a rod of tobacco of predetermined length wrapped in cigarette paper wherein the tobacco content are packed at high density at the butt end of a predetermined length and normal density for the remaining length upto the smoking end.
- the tobacco content at the said high density end primarily includes mixtures of cut and rolled stem (CRS), but can also include mixtures of graded tobacco, reconstituted tobacco, dust with binders or natural materials.
- CRS cut and rolled stem
- the normal density of such rod is in the range of 225 mg/cc to 280 mg/cc while the high density of such rod is at least 280 mg/cc
- the length ratio of normal and high density of said tobacco rod is 5:1 and is configured so as to maintain the desired smoke delivery profile.
- the high-density end of the said cigarette is wrapped with porus paper of a different colour for the identification of the butt end of the cigarette by the user.
- the present invention relates to a biodegradable dual density cigarette comprising a filler or tobacco rod and butt portion joined to each other longitudinally in a ratio of 5:1 wherein the tobacco rod is a blend of tobacco wrapped in a cigarette paper at a pressure drop of 22 to 50 mm of water column, the butt portion comprising at least cut-roll stem particles of expanded fibres of density of at least 0.28/cc wrapped in a porous paper of at least 100 mm of water gauge.
- the present invention also relates to a process for manufacturing of biodegradable dual densities cigarette comprising the steps of:
- FIG. 1 illustrates a dual density cigarette having normal density tobacco at one end and high-density tobacco at other end.
- the length ratio of normal and high density can be configured so to maintain the expected smoke delivery profile.
- the present invention provides for enhancement of smoke delivery profile comparable to normal synthetic filter cigarette as well as results in substantial lo reduction of tar and nicotine. Due to the high density tobacco at the mouth end the sogginess of tobacco when put into the mouth and the entrance of loose tobacco particles entering into the mouth is also avoided
- the cigarette is 100% biodegradable and is cost effective since the conventional machines can be used.
- This cigarette is to be smoked through high-density end and this high density tobacco portion is tipped with porous cork tipping paper of different colour for identification to enable the consumer to know that tipped portion of the cigarette is to be put in the mouth.
- High-density tobacco rods can be manufactured using tobacco material such as cut and rolled stem, graded tobacco, reconstituted tobacco, tobacco dust with binders as well as various combination of above or natural materials.
- FIG. 1 shows that the tobacco or filler rod ( 1 ) is a blend of tobacco wrapped in a cigarette paper at a pressure drop of 22 to 50 mm of water column.
- the filler rod ( 1 ) is filled with blend of tobacco comprising 75 to 85% of lamina and 15 to 25% of the expanded stem fibres or cut-roll stem.
- the lamina is normal density tobacco of 4-6 cc/gm at the rate of 12.5% oven volatile preferably 5-6 cc/gm at the rate of 12.5% oven volatile.
- the butt portion ( 2 ) comprising cut-roll stem particles of expanded fibres of the density of at least 0.28/cc wrapped in a porous paper of at least 100 mm of water gauge.
- the expanded stem is 4-7 cc/gm at the rate of 12.5% oven volatile, preferably 6-7 cc/gm at the rate of 12.5% oven volatile.
- the pressure drop in the tobacco rod is 5-9 water column per mm. of filler end while the pressure drop in the butt end is 3-4 water column per mm.
- the stem portion is the mid rib of tobacco plant leaf having lower nicotinic content and higher chloride content.
- Normal and high-density tobacco rods are manufactured on cigarette making machine using normal cigarette paper as wrapper for the rod.
- the stem of the tobacco leaf is subjected to a conventional conditioning process for 10 to 20 minutes at 30-40° C. to quench the moisture uniformly.
- the quenched stem is passed through conditioning tunnel or through a flattner or a roller to flatten the stem.
- the stem is then cut into small particles of the size 30 to 180 cpi.
- the small particles are cut through an expansion heated tunnel at a temperature of 100 to 103° C. for a period of 20 to 30 seconds.
- the particles are passed through a drier and a classifier to obtain a cut roll stem (CRS).
- the CRS are cooled at room temperature by storing in boxes rolled humidifier.
- the cooled cut rolled stem are encapsulated in a filter wrapping paper to obtain the filter butt;.
- the filler or tobacco rods are made to required length and then supplied to assembler, the purpose of this unit to assemble the normal and high density tobacco filter butts in the ratio of 5:1.
- the assembler further cuts the high-density rods in suitable pieces normally 4 to 6 pieces called “Plugs” but other combination are also possible. This is followed by assembly of these “plugs” with the normal tobacco rod and over tipping with the tipping paper of suitable width, size and colour.
- the tipping paper or plug wrap can either be normal or relatively high porous to give required smoke delivery values.
- This specially made dual density cigarette is capable of delivery of smoke profile comparable to any other conventional filters as is evident from the test results.
- Table 1 comprises of 3 sub-tables showing the density trend of micro plain cigarettes (Table 1A), Plain and regular filter type cigarettes (Table 1B) and King Size Brands (Table 1C).
- Tables 1A, 1B and 1C show the comparative tobacco density that exists in different brands of cigarette having a standard length of 59 mm. The data is taken for two years i.e. for the years 2000 and 2001. the figures show that the average density of tobacco in micro plain brands (Table 1A), filter size brands (Table 1B) and the king size brands (Table 1C) ranges between 232 mg/cc and 264 mg/cc.
- the Table 2 features the analytical data showing the comparison of Tar and Nicotine in the non-filter and dual density cigarettes.
- the analytical data reveals that the Dual Density Cigarettes shows lesser value of the tar & nicotine as compared with the non-filter cigarettes of same lengths.
- Table 3 shows the comparison of “tar” and “nicotine” yield obtained from the conventional filter tipped cigarettes, the dual density cigarettes fitted with present invention and the non-filter plain cigarette.
- the table reveals that the quality of smoke delivery of dual density cigarette is comparable with the filter cigarette.
- the tar content of the smoke from the dual density cigarette with a circumference of 24.44 mm is slightly higher than the tar content in the filter cigarette with the circumference of 24.46 mm.
