* Explanation of symbols for main parts of the drawings

1: tobacco body 2: filter

3: Tobacco 4: Anti-inflammatory tube

The present invention is to prevent the scattering of the cigarette ash and to reduce the smoke generated by injecting a tube of a flame-retardant synthetic resin film in the appropriate portion of the normal outer peripheral surface of the cigarette, and to reduce the smoke generated A tube is associated with a cigarette.

Conventionally, in order to extinguish a cigarette smoked by a smoker, a cigarette fire has been usually interviewed by pressing it on the bottom of an ashtray, and then it has been extinguished. However, during the anti-inflammatory process, cigarette ashes are scattered around, which is quite unsanitary. The long-standing defects were inherent.

The present invention focuses on the conventional drawbacks as described above, and the flame-retardant tube is placed on a proper portion of the outer circumferential surface of a normal cigarette, which will be described in detail according to the accompanying drawings.

In the normal tobacco main body 1, the anti-inflammatory flame-retardant tube 4 of the flame-retardant synthetic resin film material was made to adhere to the joint part A of the filter 2 and the tobacco 3.

In the flame retardant, a halogen compound and a group Vb element are used a lot, and in particular, flame retardancy can be further improved by using an inorganic compound such as halogen and antimony oxide or anhydrous alumina.

And the thickness of the synthetic film can be used from 1.5 microns to 75 microns, but for the purpose of this paper the most suitable thickness is 5 microns to 50 microns.

In this case, the tube 4 adhering to the joint A of the tobacco 3 and the filter 2 is moved to the end of the cigarette fire as shown in Fig. 1 (b). As (4) increases, it has a choking effect, so that it can be extinguished while preventing the generation of harmful gases and the scattering of cigarette ashes, and the combustion time can be controlled.

In addition, when necessary, the tube 4 can be removed to reuse the cigarette, and even if the cigarette is left unattended, even if the cigarette is burned up to the tube 4, the flame is naturally extinguished, thereby eliminating the risk of fire.

The present invention is described in detail through the Examples and Comparative Examples as follows.

Example 1

A 2 grams per square meter (weight at the time of drying) of the following flame retardant resin composition was coated on a 12-micron-thick polyester film with a gravure printing machine, followed by hot air drying at 170 ° C. for 30 seconds to obtain a film having excellent flame resistance.

(Flame Retardant Resin Composition)

The flame retardant film obtained as described above was cut into 3 cm wide and 2 cm long and installed in a cigarette as shown in FIG. As a result, there was a rapid anti-inflammatory effect with little smoke or toxic odor.

Example 2

The following flame-retardant resin composition was applied on the same film as Example 1 so as to have a thickness of 2 microns when dried with a gravure printing machine.

(Flame Retardant Resin Composition)

When the flame-retardant resin film was applied to tobacco as in Example 1, excellent anti-inflammatory effect was obtained.

Example 3

The flame-retardant resin composition as described below was applied onto the polyester film uniaxially axially bonded by a gravure printing machine with about 3.8 g / m 2, followed by sulfur stretching of about 3.8 times.

(Flame Retardant Resin Composition)

After successively biaxially stretching the film after heat setting at 200-230 ° C., cutting was performed to prepare a film having excellent flame retardancy.

As a result of applying the film prepared as described above to the cigarette as in the previous embodiment was able to see the excellent anti-inflammatory effect without the generation of smoke.

Example 4

In the polymerization of polyester, ethylene glycol 70 and calcium acetate 0.08 were added as a catalyst to 100 weight ratio of dimethyl terephthalate, followed by transesterification reaction. Antimony trioxide 0.8 and aluminum oxide 2.5 were added to the product, followed by side polymerization. A polymer resin having a value of 0.65 was obtained.

The resulting resin was melt-bonded at 295 ° C., stretched 3.5 times in the longitudinal direction at 95 ° C., stretched 3.8 times in the transverse direction at 140 ° C., and then heat-treated at 210 ° C. to obtain a 12-micron thick twin-axial flame retardant polyester film. .

The film was applied to tobacco as in the previous examples, and an excellent anti-inflammatory effect was obtained.

Example 5

When the 30-micron-thick polyimide film and the 12-micron-thick polyester film with excellent heat resistance were laminated using an adhesive for lamination, when the anti-inflammatory test as shown in Fig. 1 was carried out, the film was heat-shrinkable and flame-retardant at the same time. The closure effect was excellent.

Comparative Example 1

The 12 micron polyester film was cut to 3 cm in width and 2 cm in length without flame-retardant treatment and applied to tobacco in the same manner as in Example 1. As a result of the test, the anti-inflammatory effect was insufficient and only a small amount of smoke was produced.

Comparative Example 2

A 22-micron-thick polyvinyl chloride film without flame-retardant treatment was cut as it was in Comparative Example 1 and applied to tobacco. The test resulted in a slight anti-inflammatory effect but a toxic odor.

Claims (1)

In a normal tobacco body 1, a cigarette having an anti-inflammatory tube, which is characterized by injecting an anti-inflammatory tube 4 of a flame-retardant synthetic resin film material into the joint portion A of the filter 2 and the tobacco leaf 3. .
