It has. And the valve part 12 is formed, for example with thermoplastic resins, such as a polypropylene, and forms the surrounding surface part 25, the bottom face part 26, and the valve body 27 integrally.
The peripheral surface portion 25 has a substantially cylindrical shape, and is sandwiched between the inner side surface of the upper end portion of the container main body 2 and the peripheral wall portion 21 of the main body portion 11.
The bottom surface portion 26 has a substantially annular shape, and the outer peripheral portion is connected to the lower end of the peripheral surface portion 25.

The valve body 27 is formed on the inner side of the peripheral surface portion 25 from the bottom surface portion 26 toward the upper side along the axis O, and is provided radially inward from the main body portion 11. The valve body 27 includes a spring portion 31 that is connected to the bottom surface portion 26 and a tip portion 32 that is formed at the tip of the spring portion 31.
The spring portion 31 extends in a spiral shape around the axis O while being reduced in diameter toward the upper side. The lower end of the spring portion 31 is connected to the inner peripheral edge of the bottom surface portion 26.
The tip portion 32 is biased upward by the spring portion 31 so that the upper portion protrudes upward from the outlet 22A along the axis O, and closes the outlet 22A of the top wall portion 22.

  The liquid agent holding member 13 is formed of, for example, a sponge, and can hold the liquid agent. The liquid agent holding member 13 is attached to an upper end portion of the peripheral wall portion 21 of the main body portion 11 that is located on the outer side in the axis O direction of the container main body 2. And the liquid agent holding member 13 exudes the liquid agent currently hold | maintained by being pressurized.

The outer cylinder portion 14 has a substantially cylindrical shape, and is formed of a thermoplastic resin such as polyethylene. And the outer cylinder part 14 is fitted by the upper end part in the surrounding wall part 21 of the main-body part 11. As shown in FIG. Thereby, the liquid agent holding member 13 is fixed. In the illustrated example, an annular portion 35 that protrudes radially inward is formed at the upper end portion of the outer cylinder portion 14. The annular portion 35 sandwiches the lower end portion of the liquid agent holding member 13 with the main body portion 11.
Moreover, as shown in FIG.1 and FIG.2, the flange-shaped convex part 36 which protrudes toward a radial direction outward is formed in the upper end part of the outer cylinder part 14. As shown in FIG. A plurality of the convex portions 36 are formed at equal intervals in the circumferential direction over the entire circumference of the outer cylindrical portion 14, and protrude outward in the radial direction from the top wall portion 22.

  As shown in FIG. 1, the container main body 2 has a bottomed cylindrical shape, and is formed of a thermoplastic resin such as polypropylene. A male screw portion 2B is formed on the outer peripheral surface of the upper end portion of the container body 2. A cap 40 is detachably screwed to the male screw portion 2B.

Next, a method of using the applicator 1 having the above configuration will be described.
For example, when the liquid agent is an adhesive, glue, nail polish or the like, first, as shown in FIG. 3, the container body 2 fitted with the applicator 1 is moved in the direction of arrow A1 shown in FIG. The coated surface is roughened by the portion 36. Then, the liquid agent holding member 13 is pressed against the surface to be coated, and the tip portion 32 is pressed along the axis O together with the liquid agent holding member 13. At this time, since the spring part 31 constituting the valve part 12 is elastically contracted along the axis O, the closed state of the outlet 22A by the tip part 32 is released. Thereby, the liquid agent reaches the liquid agent holding member 13 from the liquid agent storage chamber via the gap of the spring portion 31 and the outlet 22A, and exudes from the liquid agent holding member 13 and is applied to the application surface.

When the liquid agent is a hair growth agent or the like, first, the liquid agent is applied to the surface to be applied in the same manner as described above. And as shown in FIG. 3, the container main body 2 with which the applicator 1 was fitted is moved to the arrow A1 direction shown in FIG. Thereby, the effect of a liquid agent is exhibited effectively. Here, since the surface to which the liquid agent is applied is not stimulated by a hand or the like, the liquid agent does not adhere to the hand. Note that the liquid agent may be applied to the surface to be coated after the surface to be coated is stimulated by the convex portion 36.
When the container body 2 fitted with the applicator 1 is tilted, the liquid agent in the container body 2 is temporarily stored in the liquid storage chamber.

According to the applicator 1 having the above-described configuration, the surface to be coated can be roughened or stimulated by the convex portion, so that appropriate measures can be taken according to the type of liquid agent filled in the container.
Moreover, the operation | movement which applies a liquid agent and the operation | movement which roughens or irritate | stimulates a to-be-coated surface can be performed continuously, without putting the container main body 2 on a desk etc.

  Next, a second embodiment of the applicator according to the present invention will be described. The embodiment described here has the same basic configuration as the first embodiment described above, and is obtained by adding another element to the first embodiment described above. Therefore, in FIG.4 and FIG.5, the same code | symbol is attached | subjected to the same component as FIGS. 1-3, and the description is abbreviate | omitted.

As shown in FIGS. 4 and 5, the applicator 50 in the present embodiment has the outer cylinder portion 51 having a rib-like convex portion 52.
The convex part 52 protrudes outward in the radial direction from the outer cylinder part 51. The plurality of convex portions 52 are formed at equal intervals in the circumferential direction over the entire circumference of the outer cylinder portion 51, and protrude outward in the radial direction from the top wall portion 22.
Further, the outer cylinder portion 51 is formed of a soft material with at least the convex portion 52 as compared with the remaining portion of the outer cylinder portion 51. Here, the convex portion 52 is formed of an elastically deformable soft material such as nitrile rubber (NBR), low density polyethylene (LDPE), or linear low density polyethylene (LLDPE). Moreover, the part except the convex part 52 is formed with material harder than the formation material of convex parts 52, such as polyethylene, for example. The outer cylinder portion 51 is formed in a portion excluding the convex portion 52 in which the wedge-shaped concave portion is formed in the portion where the convex portion 52 is formed, and then the molding material of the convex portion 52 is injection-molded to project into the wedge-shaped concave portion. The portion 52 is formed so as to be embedded. Thus, by forming the convex portion 52 in the wedge-shaped concave portion, the convex portion 52 is difficult to come off.

  In the applicator 50 having such a configuration, as shown in FIG. 5, the surface to be coated can be roughened or stimulated by sliding the convex portion 52 in the direction of the arrow A2 with respect to the surface to be coated.

  The applicator 50 configured as described above also has the same functions and effects as those of the first embodiment described above, but the convex portion 52 is formed of a softer material than the other portions of the outer cylindrical portion 51. Therefore, the surface to be coated can be prevented from being roughened or stimulated by excessive pressure.

  In the present embodiment, the outer cylinder portion 55 configured as shown in FIG. 6 may be used. That is, the outer cylinder part 55 includes a cylindrical part 56 that surrounds the main body part 11, and a rotating cylinder part 57 that has a convex part 52 formed on the outer peripheral surface thereof and can rotate around the axis O with respect to the cylindrical part 56. . An annular convex portion 58 that protrudes radially outward is formed at the center of the cylindrical portion 56. An annular groove 59 that fits with the annular convex portion 58 is formed at the central portion of the inner peripheral surface of the rotating cylinder portion 57.

  Next, a third embodiment of the applicator according to the present invention will be described. The embodiment described here has the same basic configuration as the first embodiment described above, and is obtained by adding another element to the first embodiment described above. Therefore, in FIG. 7, the same components as those in FIGS. 1 to 3 are denoted by the same reference numerals, and the description thereof is omitted.

As shown in FIG. 7, the applicator 60 in the present embodiment does not include the liquid agent holding member as in the first and second embodiments described above.
The main body portion 61 includes a peripheral wall portion 62, a top wall portion 63, and a convex portion 64. The convex portion 64 has a bowl shape that expands along the axis O toward the upper side, and is continuous with the upper end of the peripheral wall portion 62. And the convex part 64 is formed over the perimeter of the surrounding wall part 62, and the front-end | tip part protrudes toward the radial direction outer side rather than the top wall part 63. As shown in FIG.

  The applicator 60 configured as described above also has the same operations and effects as those of the above-described embodiment.

In addition, this invention is not limited to the said embodiment, A various change can be added in the range which does not deviate from the meaning of this invention.
For example, in the first and second embodiments, the plurality of convex portions are arranged in a gear shape, but may have other shapes such as a waveform. Moreover, a convex part may be continuously formed over the perimeter like 3rd Embodiment. Similarly, in the third embodiment, the convex portions are formed over the entire circumference, but a plurality of convex portions may be formed at equal intervals in the circumferential direction as in the first and second embodiments.
In the second embodiment, at least the convex portions are formed of a soft material, but the convex portions may be formed of a hard material.
And the liquid agent apply | coated using an applicator is not restricted to an adhesive agent, glue, a nail polish, a hair restorer, etc.
Moreover, although the valve part is pinched | interposed between the main-body part and the container main body, as long as the outlet of a main-body part is obstruct | occluded by the valve body so that opening and closing is possible, another structure may be sufficient.

  According to this invention, industrial applicability is recognized regarding the applicator excellent in the handleability which can respond | correspond appropriately according to the kind of liquid agent with which the container body is filled.
