The technical field to which the invention relates.

The present invention relates to tissue paper products for Smoking, such as cigarettes, and more exactly, to wrapping paper products for Smoking, which can provide a decrease in side stream smoke.

Prior art

With Smoking products for Smoking, such as cigarettes, tobacco forms the main stream of smoke to be inhaled by the smoker through the tobacco mass, and side stream smoke, which rises from the far-end area lighted products for Smoking, when it is in the process of static burning.

Measurement of side-stream smoke is performed by means of a method of using a camera with a lower end part having the form of a fish tail (fishtail method, which is disclosed in publication of Japanese KOKAI patent application No. 10-81. Previously it was proposed that a large number of decisions aimed at creating products for Smoking, which reduces side-stream smoke. One example is to add a substance which has the effect of suppressing, as a filler in paper products for Smoking. More precisely, in the publication of Japanese KOKOKU patent application No. 63-37621 disclosed adding gel magnesium hydroxide, and the Japan patent No. 2730894 disclosed the addition of a filler having a large UD is the function surface, consisting, for example, from calcium carbonate. However, the usual wrapping paper designed to reduce the side stream tobacco smoke, has disadvantages, such as the presence of expensive additives and unstable quality, depending on the production method, and still no paper proposed to reduce the side stream smoke has not found practical application on a large scale. Therefore, there is a great need for measures that reduce the side-stream tobacco smoke simpler and more efficient manner.

With this in mind, the purpose of the present invention is to design wrapping paper for products for Smoking, which can ensure the reduction of side-stream tobacco smoke simpler and more efficient manner compared to conventional wrapping paper.

Disclosure of inventions

In the framework of the present invention conducted in-depth research to achieve the above goals and received confirmation that the compound based on calcium phosphates such as tricalcium phosphate, has the property to cause a small increase in speed static burning wrapping paper, but it is expected to significantly reduce the amount of smoke in side stream smoke, if the number of contained substances, re wirausaha burning, equal to or less than the number normally found in ordinary wrapping paper by using the specified substances. However, the inventors have additionally found that when using a specified number of connections on the basis of calcium phosphate in combination with a given amount of a substance for regulating combustion in the form of salts of organic acids, such as sodium citrate, achieved a significant and unexpected effect and reduce the side stream smoke, which could not be achieved using methods of the prior art. The present invention was created based on the received data.

Thus, in accordance with the present invention proposed wrapping paper for products for Smoking, which contains a substance for regulating combustion in an amount of from 1 g/m2up to 15 g/m2and the compound based on calcium phosphate in an amount of from 1 g/m2to 30 g/m2.

Substance for regulating the combustion preferably includes a salt of an organic acid.

In accordance with the present invention it is preferable that the compound based on calcium phosphate represented tricalcium phosphate and to a substance for regulating the combustion of the contained salt of citric acid (citrate).

In addition, in the present invention it is preferable that the weight is Bertoni paper was 40 g/m 2or more and 70 g/m2or less.

The best way of carrying out the invention

The present invention will be described hereinafter in more detail.

Wrapping paper for the product to area according to the present invention can be produced by grinding the fibrous mass, which is typically used in the production of wrapping paper, and adding connections on the basis of calcium phosphate to provide a predetermined content, which will then prepared a paper weight. Pulp processed in the machine, and a substance for regulating the combustion injected into the pulp, in the process, to obtain a predetermined content. A preferred example of the pulp is the fibrous mass from flax. Weight wrapping paper is not restricted in a particular way, but it usually amounts to 20 g/m2or more and 80 g/m2or less, preferably 40 g/m2or more and 70 g/m2or less.

Substance for regulating combustion used in the present invention may be a substance of any conventional type, which is used in ordinary wrapping paper as a tool that can affect the speed of static burning wrapping paper. In this field of technology as a means to regulate th the help of well-known organic acid salts, such as potassium acetate, salt of succinic acid, a salt of tartaric acid (tartratami) and a salt of acetic acid (acetate), addition of sodium acetate, and these substances can be used in the present invention. These substances are particularly preferred sodium acetate. In this invention, the substance for regulating the combustion is contained in the wrapping paper in an amount of from 1 g/m2up to 15 g/m2. If the content of the substance for regulation of combustion is less than 1 g/m2cannot be reached, a sufficient effect of reduction in side stream smoke, while if it exceeds 15 g/m2can be violated ["lost"] stability in the manufacture of wrapping paper. The preferred amount of the substance to regulate the burning is from 1 g/m2up to 10 g/m2and more preferably from 2 g/m2up to 5 g/m2if we take into account the taste of tobacco.

Wrapping paper according to the present invention contains a compound based on calcium phosphate in addition to the substance for regulating combustion in the above number. As compounds based on calcium phosphate may be used a compound based on calcium phosphate having a molar ratio Ca/P of 1.0 to 2.0, preferably tricalcium phosphate, hydroxyapatite, or amorphous calcium phosphate. As compounds based on calcium phosphate is particularly preferred tricalcium phosphate, which is a dietary Supplement and is available on the market at a low price. In the present invention the compound based on calcium phosphate contained in the wrapping paper in an amount of from 1 g/m2to 30 g/m2. If the content of compounds based on calcium phosphate is less than 1 g/m2, it is impossible to achieve a sufficient effect of reduction in side stream smoke even when the combination of this compound with a preset number of substances to regulate combustion, while in the case, if the content exceeds 30 g/m2the strength of the wrapping paper is reduced, which complicates the manufacture of cigarettes for high-performance cigarette machine of the modern type.

Wrapping paper products for Smoking according to the present invention in addition to the above substances to regulate combustion, and compounds based on calcium phosphate may contain a filler such as calcium carbonate, which is commonly used in wrapping paper. Taking into account the increase in opacity of wrapping paper, it is preferable that the calcium carbonate was contained in a paper in the amount of about 10 g/m2in the manufacture of tissue paper products for Smoking according to the present invention.

Hereinafter the present invention will be described by using examples; however, is it the present invention is not limited to these examples.

Examples

To linen fibrous mass, which was milled to 80 degrees refining the instrument Shopper-Rigler when the degree of grinding on the Shopper, the corresponding 1 g - the way (1 g method) (the degree of grinding on the Shopper in accordance with the Japanese industrial standard P 8121, except the concentration of the slurry was set at the level of 0.1%), as an internal fillers were added spindle-shaped calcium carbonate (CA-850: the average granularity of 3.5 μm, product of Shiraishi Kogyo Co. Ltd.) and tricalcium phosphate production company Wako Junnyaku Kogyo Co. Ltd. (grade chemical reagent, sample number: 032-10855) providing a pre-determined their content in the paper, the result of which was prepared paper pulp. After that, the paper weight was processed using TAPPI paper machine of a standard type with manual control for the production of wrapping paper. Spindle-shaped calcium carbonate and tricalcium phosphate were added to obtain the content specified in table 1. For insertion in tissue paper substances for regulating the combustion of an aqueous solution of sodium acetate in a previously specified amount has been deposited and then subjected to drying, the result of which was made of paper.

Should be about the mark, what used tricalcium phosphate production company Wako Junnyaku Kogyo Co. Ltd. was a powdered tricalcium phosphate, indicating on the label "This product typically has a composition of hydroxyapatite [Ca3(PO4)2]3(Ca(OH)2."

When use is made thus wrapping paper were manufactured cigarettes. The size of the cigarettes was a size, usually called FK-size, while the circumference was 24.9 mm, the length of the column of tobacco was 59 mm, a filter length was 25 mm and the length of the paper mouthpiece was 32 mm fine-cut tobacco Used was tobacco type American blend (American mix), which is used in normal industrial manufactured products, and the filling was 0,580 g per cigarette. These cigarettes were subjected to conditioning at a temperature of 22aboutC and 60% relative humidity and then selected by mass cigarettes, component 0,885±of 0.01 was Selected so cigarettes were tested. The content of fillers (tricalcium phosphate and calcium carbonate), a substance for regulating combustion (sodium citrate) paper and the amount of smoke in side stream smoke exposure cigarettes static burning on the length of 4.9 mm by means of a method using Cam the market with the lower end part, having the form of a fish-tail for each case are shown in table 1.

As for the wrapping paper grades A-F, the amount of smoke in side stream smoke was measured for each of the cigarettes, which were made of tissue paper having different amounts of calcium carbonate and sodium citrate added to it.

As for the wrapping paper grades G-I, it was not added substance to regulate combustion, and the amount of smoke in side stream smoke was measured for each of the cigarettes, which were made of tissue paper having various amounts of fillers, calcium carbonate and tricalcium phosphate added to it.

As for the wrapping paper grades J-P, then it was added calcium carbonate (10 g/m2), which is used in ordinary wrapping paper for tobacco products, and the amount of smoke in side stream smoke was measured for each of the cigarettes, which were made of tissue paper having different amounts of calcium carbonate and sodium citrate added to it.

As the results, presented in table 1, the cigarettes that used wrapping paper grades L-P, which was a product according to the present invention produces such a small side stream smoke, which is now what should be achieved for those cigarettes, which were made using wrapping paper, obtained using a combination of conventional fillers and substances for the regulation of burning.

As described above, in accordance with the present invention can be obtained wrapping paper for products for Smoking, which can reduce side stream tobacco smoke is more efficient compared to conventional wrapping paper.
