Description

[Detailed description of the invention] The invention relates to a cigarette box in which cigarettes are stored.
In particular, it relates to a cigarette box having a cigarette ignition function.

FIG. 1 is a perspective view showing an example of a conventional cigarette box.

In this figure, numeral 1 denotes an outer box, which forms the outer shell of the cigarette box.

2 is an inner box which is slidably accommodated in the outer box 1.

Note that p, q, and r indicate the lengths of the three sides of the cigarette box, respectively.

By the way, in general, to light a cigarette, a match or a lighter that uses gas or petroleum-based liquid fuel is often used.Furthermore, convex lenses and concave mirrors have been used to condense sunlight and ignite it. It is being done.

Furthermore, the present inventor has previously proposed a cigarette structure that can be easily ignited using sunlight in order to save energy, especially fossil fuels.

FIG. 2 is an explanatory diagram showing the ignition state of a cigarette having the cigarette structure proposed by the present inventor.

In this figure, 3 is a cigarette, 4 is a convex lens, and 5 is sunlight.

Reference numeral 6 denotes a heat absorbing portion, which is provided near the end of the cigarette 3 that is to be lit, and is shaped by, for example, being colored black with ink.

Therefore, this heat absorbing portion 6 has a strong heat absorbing power, and when sunlight 5 is applied to the convex lens 4, the heat absorbing portion 6 is placed at the focal point of the convex lens 4.
When placed, the temperature of the heat absorbing portion 6 rises within a short period of time, and it is easily ignited.

However, when igniting using the above-mentioned match or lighter, or when using sunlight to ignite a cigarette with the cigarette structure proposed above, in addition to the cigarette box containing the cigarette, matches, lighter, convex lens, etc. Alternatively, you must have a separate ignition device such as a concave mirror.

The present invention was developed in view of the actual situation of cigarette lighting, and its purpose is to provide a cigarette box having a cigarette lighting function.

The cigarette box of the present invention will be explained below based on the drawings.

FIG. 3 is an explanatory diagram showing the first embodiment of the present invention.

In this figure, 1 is the outer box, 2 is the inner box, 3 is the cigarette,
4 is a solar light concentrator such as a convex lens; 5 is sunlight; 6 is the heat absorption portion; 7, 8.12 are the sides of the outer box 1, respectively;
10 is the side surface of the inner box 2, and 9 and 11 are marks.

Here, the convex lens 4 is provided in a hole formed at the end of the side surface 7 of the outer box 1, and its focal length f is shorter than the length p of one side of the cigarette box. .

In addition, the mark 9 is attached to the inside part of the side surface 8 of the outer box 1.
The star shape indicates the sliding limit position of the inner box 2 when lighting a cigarette.

Further, a mark 11 is attached to the outer side of the side surface 10 of the inner box 2, and is used to indicate the position where the cigarette is placed when it is lit. It has been done.

In a cigarette box having such a structure, the inner box 2 is pulled out from the outer box 1 to the position indicated by the mark 9, that is, by a distance r1.

Then, sunlight 5 is applied to the convex lens 4 that is shelled on the cigarette box, and the heat absorbing part 6 provided at the end of the cigarette box 3 is marked as 1.
When a cigarette is inserted and placed at the focal point of the convex lens 4, the sunlight 5 passes through the convex lens 4 and is focused.
ignites the fire.

In this embodiment, the cigarette is ignited in the small chamber of the outer box 1 formed by sliding the inner box 2, so even if the wind blows, the cigarette is ignited almost unaffected by the wind.

Also, after the cigarette is lit, the inner box 2 that has been pulled out is replaced with the outer box 1.
When the inner box 2 is pulled back by a distance r1, the lower surface of the convex lens 4 is covered with the side surface of the inner box 2, so sunlight 5 is blocked, and problems such as ignition, fire, or burns do not occur.

According to the inventors' experiments, the three sides are p-=5cm,
In a cigarette box of q2 cm, r=io Cm, the convex lens 4 is made of plastic and has a width of 1.5 cm and a length of 2.
cm, and the focal length f is 4 cm, it has been confirmed that when a cigarette provided with the heat absorbing portion 6 is ignited at noon on a sunny day, it ignites within 1 to 2 seconds.

In this embodiment, the convex lens 4 is provided on the side surface 7 of the outer case 1, but if it is provided on the side surface 12 of the outer case 1, it is possible to provide a convex lens with a wider area, that is, a convex lens with a large light-gathering power. can be easily ignited, and even an ordinary cigarette not provided with the heat absorbing portion 6 can be easily ignited.

FIG. 4 is an explanatory diagram showing a second embodiment of the present invention.

In this figure, 4 is a convex lens, 13 is a hole, 14 is a side surface of the outer box 1, and 15 is a side surface opposite to the side surface 14.

Here, the convex lens 4 is provided on the side surface 14 of the outer box 1, and its focal length f is longer than the length q of one side of the cigarette box.

Further, the hole portion 13 is provided on a side surface 15 of the outer box 1 opposite to a side surface 14 on which the convex lens 4 is provided.

In a cigarette box having such a structure, the inner box 2 is pulled out from the outer box 1 by a distance r2.

When sunlight 5 is applied to the convex lens 4 provided on the cigarette box, the sunlight 5 that has passed through the convex lens 4 is further exposed to the hole 1.
3 and focuses on the space below the outer box 1.

Then, when the heat absorbing portion 6 provided at the end of the cigarette 3 is placed at the focal point position, ignition is performed.

Note that the cigarette box of this embodiment has a convex lens 4 provided on the side surface 14 of the outer box, which has the widest area of the cigarette box, so it is possible to provide a convex lens with a wide area, that is, a convex lens with a large light-gathering power. , it ignites very easily, and even a normal cigarette without the heat absorbing part 6 ignites easily.

When the inner box 2 is pulled back into the outer box 1 by a distance r2, the inner box 2 covers the lower surface of the convex lens 4 and the hole 13, so sunlight 5 is blocked and problems such as ignition, fire, or burns are avoided. Does not occur.

According to experiments conducted by the present inventors, when the convex lens 4 is made of plastic, has a diameter of 2.5 cm, and a focal length f of 5.0 cm, a cigarette equipped with the heat-absorbing portion 6 can be ignited on a sunny day, at noon, and when there is no wind. It has been confirmed that ignition occurs within 1 to 2 seconds.

Also in this second embodiment, a star-shaped mark indicating the sliding position of the inner box 2 may be provided on the inner side of the side surface 15 of the outer box.

Furthermore, the marks in the first and second embodiments are not limited to the above-mentioned shapes or the locations mentioned above. It is clear that any shape such as a line segment, dotted line, dot, circle, or other figure may be used as long as it indicates the stationary position, and it may be provided on any side.

Note that in the first and second embodiments described above, the convex lens 4
A Fresnel lens may be used instead.

As described above, the cigarette box of the present invention is equipped with a solar concentrator, which is an igniter for lighting cigarettes, and has the effect of solving the problem of having a separate igniter.

Additionally, since the cigarette is ignited using concentrated sunlight, it is effective in saving fossil fuels.
