  As shown in FIG. 2, the inner plug 30 is a member in which a flange 32 protruding annularly in the outer diameter direction is integrally provided at an upper end of a short cylindrical peripheral wall portion 31. As shown in the present embodiment, projecting plates 34 formed by combining adjusting plates 34a, 34b, 34c, 34d, and 34e are formed on the inner peripheral surface 33 of the peripheral wall portion 31 that forms the inner plug 30. It is protruding. The adjusting plates 34a, 34b, 34c, 34d, and 34e are formed in the circumferential direction over approximately one-third of the circumference along the inner peripheral surface 33, and radially inward from the inner peripheral surface 33 in the radial direction. A plurality of adjusting plates 34 a, 34 b, 34 c, 34 d, and 34 e constituting the protruding plate 34 are provided with a gap 35.

  In other words, a U-shaped first gap 35A is formed between the adjustment plate 34a and the adjustment plate 34b which are arranged adjacent to each other in the circumferential direction, and the distance between the adjustment plate 34a and the adjustment plate 34b gradually decreases from the tip on the container axis O side toward the inner peripheral surface 33. Similarly, a second gap 35B is formed between the adjusting plate 34c and the adjusting plate 34d. As shown in FIG. 3, the first gap 35A and the second gap 35B are formed with different gap dimensions. More specifically, the gap dimension of the widest part on the tip end side (container axis O side) of each gap is such that the gap dimension W2 of the second gap 35B is smaller than the gap dimension W1 of the first gap 35A. (W1> W2).

As shown in FIG. 3, the adjusting plate 34 a and the adjusting plate 34 b are formed such that the ends on the center 36 a side of the first gap 35 A are inclined lower ends 34 a 1 and 34 b 1, and the inclined surfaces are inclined downward toward the center 36 a of the gap 35.

The closed lid 20 is screwed into the mouthpiece 12 of the container body 10 and sealed by being crowned.

Next, the operation of the coating liquid container 1 will be described.
The coating liquid container 1 is used with the lid 20 unscrewed and the inner plug 30 exposed to the outside. The user inserts a brush constituting one embodiment of the applicator into the housing portion 14 through the inner plug 30, and causes the application liquid to sufficiently adhere to the bristle portion of the brush.

Next, the user inserts the bristle portion of the brush into the first gap 35A, the second gap 35B or the third gap 35C according to the desired amount of the application liquid, and performs an ironing operation. For example, when the ironing operation is performed using the first gap 35A, the shaft of the brush is lifted vertically upward while the root portion of the bristle of the brush is lightly brought into contact with the edge 38 of the first gap 35A. It is done by doing. Then, since the excess coating liquid is scraped off from the bristle of the brush by the edge 38, the amount of the coating liquid contained in the bristle of the brush after the ironing operation can be set to the first amount and the bristle of the brush can be reduced. Can be arranged. It should be noted that the application liquid that has been ironed out flows on the adjusting plates 34a and 34b formed by the inclined surfaces, and returns to the inside of the housing portion 14 via the first gap 35A.
The same applies to the case where the same ironing operation is performed in the second gap 35B. However, the gap dimension W2 of the second gap 35B is formed to be smaller than the gap dimension W1 of the first gap 35A (W1> W2). ). For this reason, the amount of the application liquid contained in the bristle portion of the brush after the ironing operation can be reduced to the second amount smaller than the first amount, and the bristle portion of the brush can be adjusted.

Further, when the amount of the application liquid contained in the bristle portion of the brush after the ironing operation is to be set to the third amount smaller than the second amount, the third gap 35C formed with the smallest gap dimension W3 is used. Good. When the third gap 35C is used, it is performed by moving the shaft portion of the brush obliquely upward according to the inclination angle of the adjustment plate 34e. At this time, the excess coating liquid contained in the bristle portion of the brush is coated with the edge 38 at the lower end of the inclined upper end 34e2 of the adjusting plate 34e and the upper end of the inclined lower end 34d1 of the adjusting plate 34d opposed thereto. Is scraped off by the edge 38 of. At the same time, the brush moves so as to slide on the upper surface of the adjusting plate 34e, so that the bristle of the brush can be more finely arranged.
As described above, the amount of the coating liquid contained in the bristle portion of the brush is controlled by selectively using the first gap 35A, the second gap 35B, or the third gap 35C having different sizes. Therefore, the operability can be improved.
Further, when the operation of ironing the bristle portion of the brush is performed using the inner edge of the mouthpiece portion 12 of the container body 10, a part of the application liquid attached to the mouthpiece portion 12 is solidified and the opening / closing operation of the lid 20 is performed. However, performing the ironing operation using the protruding plate 34 as described above can prevent the opening and closing operation of the lid 20 from becoming difficult.

Next, the configuration of a second embodiment of the present invention will be described with reference to FIGS.
