The portable ashtray 1 of the present invention is assembled as follows. First, the shaft b is inserted into the hinge portion 9 and the hinge portion 13 with the coil spring a interposed therebetween, and the ashtray main body 2 and the outer lid 3 are hinged to be freely opened and closed. Then, the inner lid 4 is placed in the ashtray body 2 with the lid surface 14 facing upward. At this time, the inner lid is rotated while appropriately rotating the lower end of the peripheral wall portion 15 along the inner peripheral surface of the ashtray body 2. 4, the notch 15 f formed at the lower end of the peripheral wall portion 15
Get caught in 0. Then, when the inner lid 4 is pushed in while being appropriately rotated in the direction c in FIG. 7, the inclined side 15 d of the notch 15 f slides along the convex portion 10 and then comes into contact with the receiving side 15 e. At this time, as shown in FIG. 3, the inner lid 4 has a lower end of the peripheral wall portion 15 having an annular locking end portion 7a.
And the band-shaped projection 16 is placed in a state of being in close contact with an appropriate portion of the inner peripheral surface. Then, when the outer lid 3 is closed, the closing portion 11b abuts on the periphery of the ash hole 14a and closes the ash hole 14a without any gap.

Next, the opening / closing mechanism 5 is attached. First, each end of the coil spring 17 is engaged with the ashtray body 2 and the ring member 18 while the coil spring 17 is inserted through the receiving portion 8. At this time, the ring member 18 inserts the receiving hole 18d into the receiving portion 8 with the locking surface 18a facing outward and the notch 18b facing upward. Further, the cylindrical portion 19a having a shaft hole is fitted into the outside of the projection 8c having a shaft hole while being inserted into the receiving hole 18d, and the cap 19 is mounted on the outside of the knob portion 19b with the screw d. Thus, by mounting the ring member 18 in a state where the retraction force of the coil spring 17 acts, the opening / closing mechanism 5 is attached. Thus, when the ring member 18 is rotated, the opening / closing mechanism 5 applies the retraction force of the coil spring 17 to always restore the original position.

Next, the operation and effect of the portable ashtray 1 having the above-described configuration will be described together with the method of using the same. First, when the outer lid 3 is closed as shown in FIG. 3, at this time, the outer lid 3 closes the ash hole 14a of the inner lid 4 by the closing portion 11b. And the outer lid 3
In FIG. 10, a force in the cover opening direction is applied by a coil spring a attached to the hinge portion 13, and the outer cover 3 is pressed with one hand so as to oppose this force. As shown in (A), the ring member 18 is rotated, and then the hand is released from the ring member 18 after the locking projection 12a has passed the notch 18b of the ring member 18. Then, the ring member 18 returns to the original position by the retraction force of the coil spring 17, so that the locking projection 12a can be automatically locked by the peripheral wall portion 18c (FIG. B). Thus, the closed state of the outer lid 3 can be maintained by antagonizing the force in the lid opening direction by the coil spring a.

On the other hand, when trying to open the outer lid 3, the ring member 18 may be appropriately rotated while holding the knob 19a with fingers, so that a force in the opening direction is applied to the outer lid 3. Acting, the locking projection 12a passes through the notch 18b,
At this time, the engagement of the locking projection 12a by the peripheral wall portion 18c is released, so that the outer lid 3 can be automatically opened. As described above, the portable ashtray 1 can be easily operated with the outer lid 3.
It is very easy to use and can be opened and closed.

Next, when the ash is dropped by smoking, in this case, the ash can be dropped into the ashtray body 2 through the ash pit 14a of the inner lid 4. The ash dropped at this time is the ash pit 1
It collects on the bottom 6 from 4a. However, since the inner lid 4 has only the ash pit 14a formed in a part of the lid surface 14, there is little possibility that the fallen ash is scattered, and when the outer lid 3 is closed, the ash pit is formed. 14a can also be hermetically closed, so that the dropped ash does not escape outside in any state. The inner lid 4 has a band-shaped protrusion 16 formed on the outer peripheral surface of the peripheral wall portion 15, and since the band-shaped protrusion 16 is in close contact with the inner peripheral surface of the ashtray main body 2, the ash accumulated on the bottom portion 16 is formed. Does not escape through the gap between the inner lid 4 and the ashtray body 2. As described above, the portable ashtray 1 has an excellent airtightness that can prevent the fallout of the ashes from escaping.

When the dropped ash is discarded, in this case, the outer cover 3 is first opened by operating the opening / closing mechanism 5,
Next, the inner lid 4 is taken out. At this time, when the inner lid 4 is rotated in the opposite direction to the above c while holding the ashtray main body 2 with one hand, the inclined side 15d of the notch 15f becomes the convex portion 10. The inner lid 4 can be removed while sliding along. In this case, since the knurls 15c, 15c are formed on the peripheral wall portion 15 of the inner lid 4, if the knurls 15c are grasped, the finger can be reliably operated without slipping. Then, once the inner lid 4 is removed, the bottom 6 can be largely opened, so that if the ashtray main body 2 is inclined, the ash can be easily discarded.
As described above, the portable ashtray 1 has an excellent effect of preventing falling of the dropped ash, and has an opposing effect that the dropped ash can be easily discarded.

In addition, the portable ashtray 1 can be lowered to the shoulder together with the string by inserting an appropriate string into the insertion hole of the knob 19, which is convenient for carrying.

In the above description, the portable ashtray 1 has a circular shape as an example. However, the present invention is not limited to the portable ashtray 1, but may be, for example, a rectangular or elliptical one. And various shapes.
