The skirt portion 45 covers the connecting cylinder portion 20 of the measuring cylinder member 7 from above and from the outside in the radial direction.
As shown in FIG. 4, when the coating plug 9 is located at the measuring position, the connecting portion between the peripheral wall of the covering cylinder portion 42 and the skirt portion 45 is connected to the upper end portion of the top portion 19 of the measuring cylinder member 7. In a close state, the inner surface of the coating body 40 is separated from the outer peripheral surface of the top 19 of the measuring cylinder member 7.

Hereinafter, the operation of the coating container 1 of the present embodiment will be described.

As shown in FIG. 2, before the application container 1 is used, the lower end of the seal cylinder 24 of the coating stopper 9 is fitted inside the peripheral wall of the cylinder cylinder 12, and the measuring chamber 6 and the communication hole 5 are communicated with each other. It is blocked.
In order to apply the contents in the container body 2 to the coated portion S, first, the overcap 10 is moved upward to be separated from the mouth portion 3 of the container body 2 to expose the coated body 40 to the outside of the container. Here, when the overcap 10 is disengaged, the pulling protrusion 31a of the pulling cylinder 31 engages with the engaged portion 42b in the covering cylinder portion 42 of the coating body 40 in the container shaft O direction, thereby overshooting. The cap 10 pulls up both the coating body 40 and the coating plug 9, and the coating plug 9 moves to the measuring position as shown in FIG.

At this time, since the male threaded portion of the mouth portion 3 and the female threaded portion of the overcap 10 are double-threaded threads, the lead of the screw is larger than that of the single-threaded thread. Therefore, the amount of displacement in the container shaft O direction with respect to the amount of rotation of the overcap 10 in the circumferential direction can be increased. As a result, the coating body 40 and the coating stopper 9 can be quickly moved upward, and the overcap 10 can be quickly detached from the mouth portion 3 of the container body 2.

When the coating plug 9 is moved to the measuring position, the stopper protrusion 24c of the coating plug 9 comes into contact with the top wall (the opening peripheral edge of the discharge hole 8) of the connecting cylinder portion 20 of the measuring cylinder member 7, and the coating plug 9 is also moved. The first engaging protrusion 24a of the measuring cylinder member 7 gets over the first engaged protrusion 8a of the measuring cylinder member 7 upward, and the first engaging protrusion 24a first engages with the first engaged protrusion 8a. Engage from the underside of the protrusion 24a. From this state, the overcap 10 is further moved upward with respect to the mouth portion 3 of the container body 2, so that the pulling protrusion 31a in the pulling cylinder 31 of the overcap 10 is engaged in the covering cylinder portion 42 of the coating body 40. Overcoming the joint 42b upward, the overcap 10 is removed from the container body 2 and the coating plug 9 as shown in FIG.

Next, with the coating plug 9 located at the measuring position, the coating container 1 is placed in an inverted position so that the contents in the container body 2 flow into the measuring chamber 6 through the communication hole 5. As a result, a predetermined amount of contents is weighed in the measuring chamber 6.
Next, as shown in FIG. 6, when the coated body 40 is pressed against the coated portion S, the coated body 40 moves toward the coating position together with the coating plug 9. In this process, the extrapolation cylinder 25 is abutted against the regulation portion 11b of the inner plug member 4, and the lower end portion of the seal cylinder 24 is fitted inside the peripheral wall of the cylinder cylinder 12.

As a result, in the coating container 1, the communication between the measuring chamber 6 and the communication hole 5 is cut off, the discharge hole 8 and the measuring chamber 6 communicate with each other, and the inner peripheral surface of the discharge hole 8 and the coating body 40 are attached. The contents can be applied to the portion S to be coated through the gap between the outer peripheral surface of the cylinder portion 41 and the coating hole 43.
At this time, the contents are not only the gap between the inner peripheral surface of the discharge hole 8 and the outer peripheral surface of the mounting cylinder portion 41 of the coating body 40, but also the communication formed on the outer peripheral surface of the mounting cylinder portion 41. It reaches the coating hole 43 through the groove 44, and is applied to the coated portion S from the small diameter portion 43A in the coating hole 43 through the large diameter portion 43B.

After use (after coating), the lower end of the pulling cylinder 31 of the overcap 10 surrounds the covering cylinder 42 of the coating body 40 in the radial direction, and the pulling protrusion 31a of the pulling cylinder 31 is surrounded by the covering cylinder 42. The pull-up protrusion 31a is formed by screwing the female threaded portion of the overcap 10 into the male threaded portion of the mouth portion 3 of the container body 2 in a state where the engaged portion 42b is in contact with the engaged portion 42b from above. The engaged portion 42b is made to ride downward, and the overcap 10 is attached to the mouth portion 3 of the container body 2.

As described above, according to the coating container 1 according to the present embodiment, the coating wall 42A of the coating body 40 covers the discharge hole 8 from the outside of the measuring chamber 6, so that the coating wall 42A is covered with the coated portion S. When the content is applied to the portion S to be coated by pressing against, it becomes possible to prevent, for example, hair or the like on the portion S to be coated from entering the discharge hole 8, for example, as in the conventional configuration. In addition, it is possible to prevent hair or the like from being pinched between the inner peripheral surface of the discharge hole 8 and the outer peripheral surface at the tip of the coating plug 9.

Further, since the coating body 40 includes the coating cylinder portion 42, when the coating plug 9 is located at the coating position, the discharge hole 8 can be surrounded not only by the coating wall 42A of the coating cylinder portion 42 but also by the peripheral wall. Therefore, the discharge hole 8 can be reliably covered from the outside of the measuring chamber 6 with a simple configuration.
Further, since the outer peripheral surface of the mounting cylinder 41 is formed with a communication groove 44 extending in the container shaft O direction and facing the coating hole 43 in the container shaft O direction, the coating plug 9 is located at the coating position. Since the lower end of the mounting cylinder 41 is located in the discharge hole 8, even if the gap between the inner peripheral surface of the discharge hole 8 and the outer peripheral surface of the mounting cylinder 41 is narrowed, the communication groove 44 As a result, it is possible to secure a flow path for the contents between the inner peripheral surface of the discharge hole 8 and the outer peripheral surface of the mounting cylinder 41.

Further, by making the inner diameter of the upper side of the coating hole 43 along the container shaft O direction larger than the inner diameter of the lower side, the contents can be applied over a wide range to the portion S to be coated.
