Description

The present invention relates to an ashtray for cigarettes, which relates to an ashtray having a function of extinguishing cigarette smoke.

An ashtray for cigarettes (hereinafter referred to as a cigarette) is usually composed of a plate part for storing ash and butts and a wall part having about three grooves on its edges for storing smoking cigarettes. In such an ashtray, the smoked cigarette is put out in the ashtray by extinguishing the fire at the bottom of the ashtray, but at this time, a strong odor is generated and remains. In some cases, the fire of a cigarette may not be completely extinguished, and there is a risk of ignition when a large number of cigarette butts are accumulated.

In order to solve the above problems, some ashtrays having a function of extinguishing a fire when a butt with a fire is thrown in have been proposed (Patent Documents 1-3). The ashtray described in Patent Document 1 has a cylindrical container having a mortar-shaped upper surface, and a circular cigarette butter inlet having a diameter 1.5 to 2 times the diameter of a cigarette is provided at the center and vertically downwardly from the inlet. The structure has a cylindrical fire extinguishing hole having a length three times or more the diameter of the mouth. This ashtray can be used with or without water in it, but if it is not, it will take a few minutes to completely digest it. Disposal of cigarette butts becomes complicated. It is said that the cigarette will extinguish in about 10 to 15 seconds without falling inside when the cigarette is lit on the side wall surface of the fire extinguisher and tilted at an angle, but it leans against it. It is troublesome to let them do it, and it is thought that they often fall inside. In addition, it is rather large and suitable for installation in public places, and is not suitable for use on a desk or table.
The ashtray described in Patent Document 2 has a structure in which several cylinders that reach the bottom of a container are vertically set upright. However, if the inner diameter of the cylinder is larger than the outer diameter of the cigarette, the cigarette easily falls and does not extinguish the fire, and it may smolder. There is. When the inner diameter of the cylinder is the same as or slightly larger than the outer diameter of the cigarette so that the cigarette does not fall, the cigarette is easily clogged when it is inserted, and the cigarette cannot be smoothly inserted. In addition, it is rather large and suitable for installation in public places, and is not suitable for use on a desk or table.
The ashtray described in Patent Document 3 is composed of a tray, a member having a through hole with a circular cross section, and a lid member having a corrugated plate for placing a cigarette during smoking, and a fired butts is passed through the through hole. It extinguishes the fire and drops it on the saucer. This ashtray is considered to be suitable for indoor use, but the saucer is open, and the drawback is that the smoke emitted from the odor of the cinder and the cigarettes on the corrugated plate during smoking diffuses into the room. is there. Moreover, the structure is slightly complicated.

JP 08-116955 JP2006-020622 Patent No. 4648480

The problem to be solved by the present invention is a compact ashtray that can be used on a desktop, and can easily and completely extinguish the fire without stopping the smoking, and stop the generation of smoke, thereby eliminating odor and smoke. It is to provide a product that can store a considerable number of cigarette butts with almost no generation or diffusion to the outside.

In addition, in this specification, the extinguishing of the cigarette fire and the stop of the generation of smoke are referred to as “smoke extinction”.

As a result of intensive studies, the inventor of the present application has found that a lit cigarette can be extinguished by inserting it into a cylinder slightly thicker than the cigarette. Therefore, the smoke ashtray has a configuration in which the cylindrical opening for extinguishing the fire is provided in a closed container. By inserting a lit cigarette into the cylindrical opening, the cigarette is quickly extinguished and odor and smoke rarely leak outside the container. When the second cigarette has been smoked, it can be inserted into the cylindrical opening to eliminate the smoke. At that time, the first cigarette in the cylinder of the cylindrical opening is pushed out of the cylinder by the second cigarette and falls into the container. By repeating this, the smoke can be extinguished one after another and the cigarette butts can be stored in the container until the container becomes full.

At this time, the difference between the inner diameter of the cylinder of the cylindrical opening and the outer diameter of the cigarette is important. If this difference is more than a certain value, the smoke elimination efficiency decreases, and if the difference is less than a certain value, the cigarette insertion The resistance increases. The present inventor has found that the difference between the inner diameter of the cylinder and the outer diameter of the cigarette is preferably 0.4 mm or more and 1.3 mm or less, and more preferably 0.7 mm or less and 1.0 mm or more. ..

Further, when the inventor of the present application puts the smoke ash tray on a horizontal plane and uses it, the cylinder of the cylindrical opening may be positioned horizontally, but the inlet side end of the cylinder is closer to the container back side end. It has been found that tilting it higher makes the cigarette insertion much smoother. It was also found that the angle between the center line of the cylindrical opening in the longitudinal direction of the cylinder and the horizontal plane is preferably 0 degrees or more and 30 degrees or less, and more preferably 10 degrees or more and 20 degrees or less. It was If the above angle exceeds 30 degrees, the inserted cigarette is likely to fall into the container before the smoke is eliminated. If ignited cigarettes fall into the container, the cigarette butts accumulated in the container may catch fire, which is dangerous.

Further, the length of the cylinder of the cylindrical opening is preferably about half or more to twice the length of the cigarette before smoking. From the length of cigarettes sold in Japan, the length of the cylinder is preferably 30 mm or more and 200 mm or less.

The cylinder of the cylindrical opening is preferably located inside the container, but it can be provided so as to project from the container, or part of it is located inside the container and part of it is provided so as to project from the container. You can also When it is projected from the container, it has an advantage that more butts can be stored as compared with the case where it is located inside the container.

It is suitable to have one cylindrical opening, and it is placed on a desk etc. between a reception room and is supposed to be used by 2 to 4 people. Those having about 2 to 4 openings are suitable. In addition, a smoking room in an office, which is supposed to be used by about 10 people, is suitable to have a larger number of cylindrical openings. Even in a smoke ashtray having a plurality of cylindrical openings, almost no odor or smoke is generated or diffused.

The shape of the above container is not particularly limited, but it is desirable that the bottom surface be in a form that can be stably placed on a horizontal surface such as a table. The bottom surface of the container may have a spherical shape or a conical shape, but in that case, when placing it on a table, it is necessary to use a stand or the like to place it stably.

By constructing the above container with the upper part and the bottom part and making the upper part and the bottom part detachable, the butts accumulated in the bottom part can be discarded at any time. Alternatively, an opening/closing discharge port may be provided at the bottom. As for the material of the container, any fireproof and robust material can be adopted, but metal, pottery, porcelain, heat resistant glass or the like can be used.
