An enlarged diameter portion 48 is formed.

Next, the usage mode and the action and effect of this embodiment will be described with reference to the drawings.
First, as shown in FIG. 2, the assembling work is performed with the coating tool E attached to the cap body B.
At this time, the outer shaft 40 is in the fully lowered state, and the lower surface of the flange 42 is in contact with the ring wall 11 of the inner cap C.

In order to attach the cap body B in this state to the mouth cylinder portion 1 of the container body A filled with the content liquid, the tip portion of the coating tool E is inserted into the content liquid from the mouth cylinder portion 1 of the container body A. In the cap body B, the lower end of the inner circumference of the inner cap C reaches the upper end of the guide ring 6 while overcoming the first male screw portion 5 screwed into the mouth cylinder portion 1 of the container body A, and the cap body B reaches the upper end. Is tilted with respect to the mouthpiece 1 so that it is not attached.
After that, when the outer peripheral wall 21 of the outer cap D is rotated clockwise, the inner cylinder wall 22 of the outer cap D is driven by the second male screw portion 25 screwed on the outer circumference to drive the outer shaft 40. It is screwed with the second female threaded portion 46 screwed on the inner circumference of the cylinder 41 to try to lower the outer shaft 40, but the flange 42 of the outer shaft 40 comes into contact with the ring wall 11 of the inner cap C. Therefore, it cannot descend from this state.

Therefore, the drive cylinder 41 of the outer shaft 40 rotates together with the inner cylinder wall 22, and the function of the detent mechanism including the detent rib 45 of the drive cylinder 41 and the guide flute 13 of the inner cap C As a result, the inner cap C rotates together with the outer cap D, and as shown in FIG. 1, the first female screw portion 12 screwed on the inner circumference of the side peripheral wall 10 and the mouth of the container body A. The first male threaded portion 5 screwed on the outer periphery of the tubular portion 1 is screwed to close the lid, and the mounting work is completed.
At the time of closing the lid, the container body A can seal the inside of the container body A by having the upper end portion of the inner circumference of the mouth tube portion 1 in close contact with the outer circumference of the tapered portion 43 of the outer shaft 40.

Next, in order to use the container with the applicator filled with the content liquid, first, when the outer cap D is rotated counterclockwise from the state shown in FIG. 1, the first male screw portion 5 and the first female screw portion 12 are used. Since the screwing of the first threaded portion consisting of is stronger than the screwing of the second threaded portion consisting of the second male threaded portion 25 and the second female threaded portion 46, the outer cap D is formed on the outer periphery of the inner cap C. By rotating the inner cylinder wall 22 at the same time while idling, the second male screw portion 25 and the second female screw portion 46 are screwed together to raise the drive cylinder 41 of the outer shaft 40.

Eventually, as shown in FIG. 4A, when the upper end portion of the drive cylinder 41 of the outer shaft 40 abuts on the lower surface of the top wall 20 of the outer cap D and the flange 42 abuts on the lower end of the inner cylinder wall 22. , The drive cylinder 41 stops ascending.
Then, the drive cylinder 41 rotates together with the inner cylinder wall 22, and the inner cap is operated by the action of the detent mechanism including the detent rib 45 of the drive cylinder 41 and the guide vertical groove 13 of the inner cap C. As shown in FIG. 5, C has a first female screw portion 12 screwed on the inner circumference of the side peripheral wall 10 and a first male screw portion 5 screwed on the outer periphery of the mouth cylinder portion 1 of the container body A. The lid is unscrewed and opened, and the opening work is completed.

Next, when the coating tool E is taken out from the content liquid in the container body A, the content liquid not only permeates the brush 34 but also enters the liquid reservoir 36 which is a recess formed by the plurality of obstruction plates 37. The content liquid is retained, and the content liquid held in the liquid reservoir 36 can be gradually replenished through the intermittent portion 38 and permeated into the brush 34.

Further, in order to facilitate replacement of the content liquid, when the cap body B is not used before opening, the outer shaft 40 of the coating tool E covers the liquid reservoir portion 36 of the inner shaft 30 with the reduced diameter portion 47 of the cover portion 44. The seal is sealed by, and the seal is released by the enlarged diameter portion 48 of the cover portion 44 at the time of use.

Further, since the inner cylinder wall 22 of the outer cap D has an air hole 26 formed at the lower end portion, air is collected between the inner cylinder wall 22 and the outer shaft 40, and the movement of the outer shaft 40 becomes worse. Can be prevented.
Further, it is possible to prevent the lower end portion of the inner cylinder wall 22 and the flange 42 of the outer shaft 40 from being in close contact with each other and causing poor movement.

Next, in order to reattach the cap body B to the mouth cylinder portion 1 of the container body A, the outer peripheral wall 21 of the outer cap D is rotated clockwise from the state shown in FIG.
Then, as described above, since the screwing of the first screw portion is stronger than the screwing of the second screw portion, the outer cap D is an inner cylinder that rotates at the same time while idling around the outer circumference of the inner cap C. The wall 22 is screwed with the second female threaded portion 46 screwed on the inner circumference of the drive cylinder 41 of the outer shaft 40 by rotating the second male threaded portion 25 screwed on the outer circumference, and the outer shaft 40 is screwed. Begins to descend.

After that, the flange 42 of the outer shaft 40 comes into contact with the ring wall 11 of the inner cap C, and cannot descend from this state.
Therefore, the drive cylinder 41 of the outer shaft 40 rotates together with the inner cylinder wall 22, and the function of the detent mechanism including the detent rib 45 of the drive cylinder 41 and the guide flute 13 of the inner cap C As a result, as shown in FIG. 1, the inner cap C has a first female screw portion 12 screwed on the inner circumference of the side peripheral wall 10 and a first male screw screwed on the outer periphery of the mouth cylinder portion 1 of the container body A. The portion 5 is screwed into the closed state.

In the container with a coating tool of the present invention, when the content liquid contained in the coating member is reduced during the coating of the content liquid, the content liquid can be gradually replenished from the liquid reservoir and permeated into the coating member for coating. The content liquid does not dry out and become uneven on the way, and the content liquid can be applied neatly.
In particular, it is suitable as a container with a coating tool used for nail polish or the like, which needs to be applied little by little by a coating member such as a brush.
