Description

A sleeve-type low-hazard cigarette and its preparation method

technical field

The invention relates to the technical field of cigarette preparation, in particular to a sleeve-type low-hazard cigarette and a preparation method thereof.

Background technique

With the "Framework Convention on Tobacco Control" (FCTC) proposing a ban on prohibiting the spread of tobacco smoke in public places, it has formed a strong impact on traditional tobacco products that traditional cigarettes dominate the market. Therefore, cigarette product innovation has become an inevitable choice for the tobacco industry. Tobacco industries around the world have taken the research and development of smokeless tobacco products as one of the important ways to solve the future development of the tobacco industry.

At present, smokeless tobacco products mainly include heated smokeless tobacco products, chewing tobacco and snuff. Among them, heated smokeless tobacco products are the focus of research and development by foreign tobacco companies. PM company will focus on research and development to reduce the combustion temperature of smokeless tobacco products, in order to make the tobacco release flavor by heating instead of burning, so as to win the favor of consumers.

PM company has developed various forms of patented technologies for electric smoking systems. For example, the electric smoking system disclosed in EP1927146 includes a special electrically heated cigarette and a reusable lighter. Electric heating cigarettes are composed of tobacco column, tubular filter, filter plug, adsorbent, flavoring agent and so on. The reusable lighter includes a casing, a power supply, a heating device, a control circuit and the like. The characteristic of the smokeless tobacco system is that it can smoke ordinary cigarettes, does not need specially manufactured tobacco products, and has a lower cost of use.

RJR's Eclipse brand of cigarettes basically heats tobacco rather than burns it. At one end of the cut tobacco, the charcoal wrapped in heat-insulating material can evenly heat the cut tobacco roll. When the smoker smokes, the hot air passes through the cigarette and releases the components of the shredded tobacco and glycerin, which can reduce the environmental smoke by 90%. JT Company has conducted research on heating materials for smokeless tobacco products, and developed a heating material that can reduce carbon monoxide emissions, mainly composed of calcium carbonate and binders. The working temperature of the heating material is less than 1000 ℃, which is significantly lower than other materials, so the production of carbon monoxide can be greatly reduced.

Contents of the invention

The purpose of the present invention is to provide a sleeve-type low-hazard cigarette and a preparation method thereof, which can greatly reduce harmful components in smoke.

The technical scheme that the present invention solves technical problem is:

The structure of the cigarette is composed of three main parts: the first part is a combustion heat source made of charcoal, which is hollow and cylindrical, and the outside is wrapped with ordinary cigarette paper. The second part is just inserted into it; the second part is a porous material wrapped in aluminum foil or tin foil paper (such as activated carbon, montmorillonite, kaolin, etc., and added glycerin, tobacco flavors, nicotine, water-mixed additives), and rolled Made into a cylinder, the outer diameter of the second part is the same as the inner diameter of the first part, and the length is the same as that of the first part. The hardness of the second part of the cylinder is 65-80%; the third part is the supporting part of the mouth, which is also divided into two small parts. Part: The end of the cigarette branch is a ring-shaped breathable metal bracket, and its inner diameter is consistent with the outer diameter of the second part. The second part of the cylinder can be inserted into it to play a fixed role. Its outer diameter is consistent with the outer diameter of the first part. There is no obvious unevenness; the mouth-containing end is a filter made of acetate fiber or plastic, which plays the role of heat insulation and filtration.

The total length of the three parts of the cigarette is 84mm, the outer circumference is 24mm, the length of the first part and the second part are both 50mm, the wall thickness of the first part is 1-2mm, and the length of the third part is 34mm. 10mm, the length of the mouth-containing end is 24-29mm.

The first part and the second part are combined by nesting, and the two small parts of the third part are wrapped and connected into a whole with aluminum foil or tin foil. Since the second part is inserted into the metal ring of the third part by 5-10mm, viewed from the burning end of the cigarette, the second part will be recessed 5-10mm into the inside of the cigarette compared with the first part.

Compared with the prior art, the present invention has the following positive effects:

① From the appearance point of view, the design of cigarettes is basically the same as that of traditional cigarettes, and it can even maintain the habit of consumers to play cigarette ash, so that consumers can adapt more quickly;

② Innovated the structure of traditional cigarettes, and proposed a "sleeve-type" structure design for peripheral heating. Based on this design, each part of the material, length, shape, and the type and amount of additives can be easily changed. Flexible; the second part is a porous material wrapped in aluminum foil or tinfoil. Because most of the new cigarettes use tobacco flakes as fillers, it wastes tobacco, increases costs, and limits the amount of additives added. The porous material adopted in the patent of the present invention can provide a larger specific surface area, better fix the additive, increase the dosage, and reduce the manufacturing cost of the cigarette.

③ The design of this cigarette can greatly reduce the harmful components in the smoke.

Detailed ways

Example 1:

As shown in Figure 1, the sleeve-type low-hazard cigarette of the present invention includes three main parts: the first part 1 is a combustion heat source made of charcoal, which is hollow cylindrical and wrapped with ordinary cigarette paper outside, and its inner diameter is the same as The outer diameter of the second part 2 is consistent, and the second part can be inserted into it just right; the second part is a porous material wrapped in aluminum foil or tin foil (such as activated carbon, montmorillonite, kaolin, etc., and added glycerin, tobacco flavor , nicotine, and water mixed additives, in which the porous material can be in the form of granules or flakes or filaments, the additive can be glycerin: tobacco flavor: nicotine: water = 10:3:2:1), and rolled into Cylinder, the porous material can adopt the existing technology; the outer diameter of the second part is consistent with the inner diameter of the first part, the length is the same as that of the first part, the hardness of the second part of the cylinder is greater than 65%, and the third part is the supporting part of the mouth , is also divided into two small parts: the cigarette support end 3 is a ring-shaped breathable metal bracket, and its inner diameter is consistent with the outer diameter of the second part, so that the second part of the cylinder can be inserted into it to play a fixing role. The outer diameter of the first part is consistent, and there is no obvious concave-convex feeling after being combined; the mouth-containing end 4 is a filter tip made of acetate fiber or plastic, which plays the role of heat insulation and filtration.

The amount of additive added is 80% of the hardness of the rolled cylinder, and the mixing ratio of additives is glycerin : Tobacco flavoring: Nicotine: Water = 10:3:2:1; The third part of the mouthpiece is cellulose acetate. The total length of the cigarette is 84 mm and the circumference is 24 mm.

Example 4:

The length of the first and second parts is 50mm, the thickness of the tube wall of the first part is 1mm, the length of the cigarette end of the third part is 8mm, and the length of the mouth end is 26mm. Fill it with kaolin filamentary material, add glycerin, tobacco flavor, nicotine, and water mixed additives and roll it into a cylinder. The amount of additive added is 75% of the hardness of the rolled cylinder. The additive mixing ratio is: Glycerin: tobacco flavoring: nicotine: water = 10:3:2:1; the first part and the second part are separated by air; the material of the third part is cellulose acetate. The total length of the cigarette is 84 mm and the circumference is 24 mm.
