Description

[Detailed explanation of the invention] This invention is based on the idea that when a half-smoked cigarette is placed in the ashtray,
This relates to a fireproof ashtray that prevents a fire from starting even if a rolled cigarette falls outside the ashtray.

In the past, smokers would pull the ashtray close to them, light a cigarette, and place the unsmoked cigarette in the cigarette holder in the ashtray while smoking, not only when they were awake, but also when they were sleeping. I get lost in my thoughts, and sometimes I forget my cigarette and fall asleep, and even when I'm awake, I sometimes leave my seat to do some errands, and the unlit cigarette that I left in the ashtray burns and burns away. This caused the center of gravity to shift, causing it to fall outside the ashtray, spreading to combustible materials and causing a fire.

This idea aims to eliminate the cause of misfires by improving the structure of the ashtray from the standpoint of fire prevention and ensuring that embers of cigarettes do not fall outside the ashtray.

The gist of this idea is to create an outer wall around the outer periphery of the ashtray, and a groove between the two. The same number of chevron-shaped protrusions as the cigarette-holder recesses of the ashtray are provided, and the apexes of the chevron-shaped protrusions are located at positions corresponding to the cigarette-holder recesses of the internal ashtray. It is made slightly higher than the height of the bottom of the recess.

The configuration of this invention will be explained below with reference to diagrams.

Fig. 1 shows an example of a circular ashtray, Fig. 2 is an enlarged view of the main part of Fig. 1, Fig. 3 is an end view cut along the line A-A in Fig. 1, and Fig. 4 shows an example of a hexagonal ashtray. Figure 5 shows an example of an ashtray with a hexagonal outer wall and a circular inner wall.

Figure 1 shows that the internal ashtray 2 has five cigarette holder recesses 4.
An example is shown in which the outer wall 3 has five chevron-shaped protrusions 6, and a cross section taken along the line A-A is shown in FIG.

In FIG. 1, an outer wall 3 is provided around the outer periphery of an ashtray 2. A groove 5 between the two is made large enough to comfortably fit one rolled cigarette 1 horizontally into the groove. The same number of chevron-shaped protrusions 6 as the four cigarette holders 4 are provided, and the apex 6A of the chevron-shaped protrusions 6 is provided at a position corresponding to the cigarette holder recess 4 of the internal ashtray, and the height of the chevron-shaped protrusions 6 is is slightly higher than the bottom 4A of the cigarette holder recess 4.

Next, how this invention is used will be explained.

In FIGS. 1 and 2, when the cigarette 1 is placed in the cigarette holder recess 4, the cigarette 1 is not placed correctly in the cigarette holder recess 4 due to the chevron-shaped protrusion 6 on the outer wall.
As shown in FIG. 2, which is an enlarged view, it is placed offset by an angle α to either the left or right of the center line XX.

Then, as the tip of the cigarette 1 burns and becomes shorter, the center of gravity moves toward the front in the figure, and the cigarette 1 loses stability and tends to slide outward from the internal ashtray.

Then, since the cigarette end 1'' side of the cigarette 1 hits the slope slightly below the apex 6A of the chevron-shaped protrusion 6 on the outer wall, the cigarette 1 slides down along the slope and just touches the ashtray 2 inside.
Since the width of the groove between the outer wall 3 and the outer wall 3 is sufficient to store one cigarette horizontally, one cigarette can be stored horizontally.
The cigarettes fall into this groove 5 and never fall outside the outer wall 3, so that fires caused by mishandled cigarettes can be prevented.

In addition to the round type shown in Figure 1, Figure 4 shows a type with a hexagonal inner ashtray and a hexagonal outer wall, and Figure 5 shows a type with a circular ashtray and a hexagonal outer wall. However, it goes without saying that it can take many other forms.

Actual test results show that the narrowest distance 7 between the protruding part of the internal ashtray and the outer wall is 1.5 to 1.5 the diameter of a cigarette.
Good results were obtained by setting the amount to about twice as much.

This device has the structure detailed above, so even if you place a lit cigarette in the ashtray and leave it there for some reason, the cigarette will burn, shorten, and fall out of the ashtray. Since the cigarette does not fall into the predetermined groove and fall outside, it is possible to completely prevent the misfire caused by mishandling of the cigarette.
