[Industrial applications]

 The present invention relates to an applicator. More specifically, the tip portion is provided with a small pipe portion, a cleaning portion biased forward by the resilient portion and slidably arranged in the small pipe portion, and the small pipe portion is continuously provided to the front portion of the cleaning portion. The present invention relates to an applicator configured by an applicator part protruding from the part.

[0002]

[Prior art]

 Conventionally, as disclosed in, for example, Japanese Utility Model Publication No. 1-128875, there is known a configuration in which a cleaning portion (bar-shaped pressing member) biased forward by a resilient portion is slidably arranged in a small tube portion. However, when the tip of the applicator having the above-mentioned configuration is directed downward for a long period of time, the application liquid may be solidified in the small tube part and unusable.

In connection with this, a configuration in which the coating liquid or dust solidified in the vicinity of the tip hole is removed by striking the pendulum forward with respect to the cleaning portion is disclosed in Japanese Utility Model Laid-Open No. 59-93774. It is disclosed in Japanese Utility Model Laid-Open No. 58-115378.

[0004]

[Problems to be solved by the device]

 However, even though these conventional applicators can remove a small amount of the solidified coating liquid in the vicinity of the tip hole, the coating liquid solidified from the vicinity of the tip hole to the inner depth can be removed during application. It could not be removed by simply pressing the coating part.

The present invention is intended to solve the above-mentioned conventional problems, and a simple coating solution which is solidified not only in the vicinity of the tip hole but also in the inner part of the small tube portion of the small tube portion which is easily clogged is easily formed. It is intended to provide an applicator that can be removed by various operations.

[0006]

[Means for Solving the Problems]

 The applicator of the present invention has a tip end portion including a small tube portion 1, a cleaning portion 2 biased forward by a resilient portion 3 and slidably disposed in the small tube portion 1, and a front portion of the cleaning portion 2. And an applicator 4 which is connected to the cleaning unit 2 and protrudes from the small tube unit 1. The applicator 4 is provided with a receiving unit 5 connected to the cleaning unit 2, and a pendulum 6 is provided in front of the receiving unit 5. The condition is that the pendulum 6 is arranged so as to be movable in any direction, and the pendulum 6 can collide with the receiving portion 5 by a shaking operation.

The small tube portion 1 may have at least a small-diameter hole having an appropriate length in the axial direction penetrating the inside thereof, and a valve seat, a ball seat, or the like may be formed on the inner wall thereof. Further, the outside may have any shape other than the cylindrical shape. Further, the small tube portion 1 may have a structure integrally formed with a neck member, a holder member, or the like attached to the tip portion of the main body, or a structure formed by another member and attached to the tip portion. Further, the material is preferably metal, ceramic, plastic or the like.

The resilient part 3 may be any member that urges the cleaning part 2 forward, and includes, for example, a spring body such as a coil spring, an elastic body such as sponge and rubber, and a stretchable bellows-like member. , Adopted as appropriate.

The coating unit 4 may be, for example, a ball that also serves as a valve body, a unit having a flange-shaped valve unit, or a unit in which the tip of the cleaning unit 2 is projected.

In addition to the configuration in which the cleaning unit 2 is in contact with the separate coating unit 4, the coating unit 4 may be fixed to the tip, or the coating unit 4 may be integrally formed. . The cleaning section 2 may have any shape outside the small tube section 1 as long as it is slidably arranged in the small tube section 1. Furthermore, the cleaning unit 2 and the elastic unit 3 are appropriately adopted such as a configuration in which they are continuously provided via separate members or a configuration in which they are integrally formed.

It is effective that the receiving part 5 is formed integrally with the cleaning part 2 or the elastic part 3, or is formed separately and attached to the cleaning part 2. Further, the position of the receiving portion 5 may be either in front of or behind the resilient portion 3, or at the same position as the resilient portion 3. Further, its shape is also appropriately selected within a range in which the pendulum 6 can collide.

The pendulum 6 may have any shape such as a cylindrical shape, a spherical shape, or a rod shape. Further, the material thereof may be any of metal, plastic, ceramic and the like as long as the pendulum 6 can be constructed so as to have an appropriate weight. Further, the number is set to an appropriate number (one or a plurality).

[0013]

[Action]

 By performing the shaking operation, the pendulum 6 collides with the receiving portion 5. Then, the cleaning unit 2 is momentarily greatly moved rearward in the axial direction and is immediately returned to the original position by the urging of the elastic unit 3. By the operation of the cleaning section 2 having a large amplitude, the solidified coating liquid in the small tube portion 1 extending from the front end hole 11 to the inner depth is removed and redissolved in the rear coating liquid.
