Abstract

PURPOSE:To obtain a cigarette with automatically extinguishing function by slidably fitting around a cigarette a short cylinder formed using a nonflammable filmy material such as metallic foil to enable extinguishment to be accomplished without the need for manual extinguishing operation by setting said short cylinder at a desired extinguishing position. CONSTITUTION:The objective cigarette can be obtained by slidably fitting around a cigarette 1 a short cylinder 2 formed using a harmless nonflammable filmy material such as metallic foil or tin foil.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to cigarettes, particularly cigarettes that have an autoextinguishing function and are extremely useful for fire protection. Conventional technology Cigarettes that have been widely used in the past come in both double-cut and filter-equipped types, but in both cases, after smoking, the smoker must extinguish the cigarette by rubbing it out. It required a digestive operation performed with active will. Problems to be Solved by the Invention However, it is common for people to carelessly leave a lit cigarette in the ashtray while smoking and forget to extinguish the cigarette, or sometimes the cigarette is not completely extinguished even though they were intended to be extinguished. There are some smokers who simply throw away their cigarettes, and cigarettes have long been considered a typical cause of fires. The present invention has been devised in order to solve the above-mentioned problems with cigarettes, which are a typical example of the cause of fires. Means for Solving the Problems It is an object of the present invention to provide a cigarette with a new structure that is extremely useful for fire prevention by imparting a fire extinguishing function. To explain using FIGS. 1 to 3, which correspond to embodiments, the cigarette according to the present invention has a metal foil on the circumferential surface of the cigarette 1l. ii Short cylinder body 2 molded using harmless non-combustible film material such as paper
It is characterized by being slidably fitted together. Operation According to the present invention, by using the above-described means, the smoker first slides the short cylinder 2 to an arbitrary set position of the cigarette 1 at which he or she desires to extinguish the cigarette before smoking. The cigarette 1 is ignited and gradually burns, and when the combustion reaches the set position of the short cylinder 2, the cigarette 1 is ignited at the set position by the short cylinder 2 made of a harmless non-combustible film material. Because it is surrounded by a fire, it automatically extinguishes the coals due to lack of oxygen. As mentioned above, the extinguished part of the cigarette becomes carbonized and solidified due to lack of oxygen, so ash does not scatter and there is no need to dispose of the ash. Furthermore, since the short cylinder body 2 that fits around the circumferential surface of the cigarette 1 is made of a film material, there is almost no change in the original shape and dimensions of the cigarette 1, so there is no discomfort. Moreover, the conventional packaging box structure for various cigarettes can be used as is. Embodiments Below, embodiments of the present invention will be explained with reference to the drawings.
In the figure, a short cylindrical body 2 made of harmless non-combustible film material such as metal foil or silver paper is slidably fitted around the circumferential surface of a cigarette l. The above-mentioned cigarette 1 may have any form, as long as it is double-cut or equipped with a filter. Metal foil is a typical example of a harmless non-flammable film material used as a molding material for the short cylinder 2, but it may be used in cases where the metallic luster on the surface or metal irritation is not desired, or to improve slippage during sliding. For example, so-called silver paper, which is made by integrally attaching paper to the front or back side of metal foil, may also be used. The short cylindrical body 2 is thus formed into a short cylindrical shape using a harmless non-flammable film material such as metal foil or silver paper so as to have an inner diameter that can be slidably fitted to the paper-wrapped Tapaco l. It may be formed into a cylindrical shape from the beginning by extrusion molding or the like, or it may be formed into a cylindrical shape by bonding both edges with an adhesive or the like. It does not matter how the cylinder 2 is formed. The length of the knot is not particularly limited, but it is possible to extinguish the fire in about 4 to 5 am, and preferably 71 or more in order to extinguish the fire quickly and completely. The short cylindrical body 2 is slidably fitted in advance to the circumferential surface of a cigarette l and then provided to the market.
At the time of smoking, the smoker slides the short cylinder 2 to any desired setting position to check the cigarette l and extinguish the cigarette. Therefore, as shown in FIG.
A small protruding piece 3 is provided extending from the upper edge, and the small protruding piece 3 is bent inward to lightly act as a stopper. It is possible to make it lock and hold by aligning it with the end position of the eye. With this structure, when the smoker slides the short cylindrical body 2 to an arbitrary setting position, the small protrusion 3 rises up and does not interfere with sliding. Alternatively, as shown in FIG. 3, a small connecting piece 4 is extended to the end of the short cylinder 2, and the small connecting piece 4 is inserted and adhered to the inside of the outer wrapping paper 6 of the filter 5 in advance to form the short cylinder. 2 to small connecting piece 4
It is also possible to connect the filter 5 to the exterior paper 6 of the filter 5 via the short cylinder body 2 and to position the short cylinder body 2 aligned below the filter. This is a structure in which when the smoker slides the short cylindrical body 2 to an arbitrary setting position, the small connecting piece 4 breaks. As mentioned above, hold the small connecting piece 4 and attach the short cylinder 2 to the filter 5.
Instead of the means for connecting to the outer wrapping paper 6, an arrangement may also be adopted in which adhesive is lightly applied to one point on the inner surface of the short cylinder 2, and the short cylinder 2 is temporarily fixed at an arbitrary position on the cigarette 1. obtain. Effects of the Invention As described above, the present invention allows the smoker to easily slide the short cylinder body 2 to any preset position desired for extinguishing the cigarette l at the time of smoking,
The fire can be extinguished automatically at the set position, and there is no need for any fire extinguishing operations such as rubbing after smoking, which is extremely useful for fire prevention. In addition, since the extinguishing part is carbonized and solidified, there is no need to dispose of the ash, making it convenient and easy to manufacture, making it easier to manufacture than conventional cigarettes.
Since there is almost no change in dimensions, it does not cause any discomfort and has excellent effects such as being easy to implement.
