These are formed, for example, by injection molding synthetic resin material, but are not limited to this.

The container main body 10 has a configuration in which a cylindrical outer wall portion 13 and a round-bottom containing portion 14 filled with a coating liquid are integrally provided. A male screw 15 is engraved on the portion 12 .
The lid body 20 is a topped cylindrical member in which a side wall portion 22 hangs down from the outer edge of a disk-shaped top wall 21, and a convex portion 23 is provided around the inner peripheral surface of the side wall portion 22. Furthermore, a female thread 24 that can be screwed into the male thread 15 on the container body 10 side is engraved on the lower end thereof. A packing 40 for ensuring sealing is attached to the inner surface of the top wall 21 of the lid 20 via double-sided tape (not shown). A configuration without the packing 40 may be employed. For example, an inner seal suspended from the inner surface of the top wall 21 of the lid body 20 is brought into close contact with the inner peripheral surface of the mouth tube portion 12 of the container body 10 to improve sealing performance. It may be configured to ensure.

As shown in FIGS. 2 and 3, the inner plug 30 is a member in which a flange 32 annularly projecting in the outer diameter direction is integrally provided around the upper end of a short cylindrical peripheral wall portion 31 . Further, as shown in this embodiment, a protruding plate 34 is integrally protruded from the inner peripheral surface 33 of the peripheral wall portion 31 forming the inner plug 30 .
The protruding plate 34 has a pair of base end portions 34a provided on the inner peripheral surface 33 of the peripheral wall portion 31, and a tip end portion 34b protruding from the base end portions 34a in the container axis O direction. The tip portion 34b is formed to have an inclined posture in which the tip portion 34b is lifted upward with respect to the portion 34a.

As shown in FIG. 4A, the projecting plate 34 has a distal end portion 34b formed in a circular shape in a plan view, and a base end portion 34a having a substantially semicircular through hole 35 formed therein. The tip portion 34b is formed with a radius of curvature R2 smaller than the radius of curvature R1 of the through hole 35 on the side of the base end portion 34a (R1>R2), and is convex upward and has a curved cross-sectional shape in the width direction. (See FIG. 4(c)), and the protruding plate 34 is formed in a shape (semi-elliptical shape) resembling a nail shape as a whole.
Here, the width direction is a direction (for example, the cc line in FIG. ), but this width direction also includes a direction intersecting the imaginary axis x at a certain angle.

Further, as shown in FIG. 3(b), an edge 36 protruding toward the inner peripheral surface 33 and formed at an acute angle is provided at the upper end edge of the through hole 35 of the protruding plate 34. A roundness 37 is formed at the upper end of the tip portion 34b along the tip portion 34b.
The inclined posture of the protruding plate 34 is not limited to the inclined posture in which the distal end portion 34b is lifted upward with respect to the proximal end portion 34a as described above. On the other hand, it is also possible to adopt an inclined posture in which the tip portion 34b side is lowered downward.
It is also possible to adopt a configuration in which the through hole 35 is not provided between the inner peripheral surface 33 of the inner plug 30 and the protruding plate 34. For example, the bristle portion 51 side of the brush 50 is inserted into the through hole 35, and the shaft portion 52 is inserted into the base end portion 34a of the projecting plate 34 or the flange 32 of the inner plug 30. By supporting the brush 50 with the inner edge of the container body 10, the brush 50 can be held in an upright state.

For example, when the amount of the coating liquid absorbed by the bristles of the brush is large, the bristles are lightly brought into contact with the edge 36 of the protruding plate 34, and the shank of the brush is lifted vertically upward. good to go As a result, excess coating liquid is scraped off from the bristles of the brush by the edge 36, so that the amount of the coating liquid contained in the bristles of the brush after the squeezing operation can be reduced.

In addition, the user can apply the coating liquid on the surface 34A of the protruding plate 34 on a trial basis by sliding the bristles of the brush against the surface 34A. Since the projecting plate 34 is formed to resemble the shape of the nail, the user can easily imagine the state of the surface of the nail after application by performing test coating without applying to the surface of the actual nail. Moreover, since the protruding plate 34 is formed to have an inclined posture in which the tip portion 34b is lifted upward, trial coating can be performed as if coating the surface of an actual nail. The coating liquid squeezed off at 34A can be returned into the container 14 .

A roundness 37 is formed at the upper end of the tip 34b of the protruding plate 34, so that when the bristles of the brush are slid from the base 34a toward the tip 34b for application, the bristles are scraped off at the tip 34b. Since the amount of the coating liquid contained in the bristles of the brush is reduced, the amount of decrease in the coating liquid contained in the bristles of the brush can be reduced, and as a result, trial coating can be performed continuously. At the same time, it is also possible to condition the bristles of the brush on the surface 34A of the protruding plate 34 and arrange them neatly.
