  However, even the applicator of Patent Document 3 cannot be applied firmly because the applicator, called a cover, is thin and elastic.

  Further, Patent Document 4 is an applicator having a metal application body, but the discharge hole of the application liquid is formed of a resin, and a feel such as a cool feeling peculiar to metal cannot be obtained during application.

  In view of the above problems, the present invention can provide a feel specific to a metallic member at the time of coating, and can apply a firm coating and have a design characteristic unique to a metallic member. It is an object to provide tools.

According to the present invention, a coating liquid such as a fluid cosmetic material is accommodated in a housing portion provided with a shaft main body, and an application body for applying the coating liquid in contact with a target portion is attached to a distal end portion of the shaft main body and a front shaft. In the liquid applicator that is fixed through the push-out mechanism and pushes the coating liquid stored in the storage portion toward the application body by a feeding mechanism provided at the rear portion of the shaft main body.
The application body is a sphere in which a through hole for discharging a coating liquid is formed at the center of the tip portion, and a discharge port is opened at the tip portion, and at least the surface of the application body and the periphery of the discharge port is a high thermal conductivity material. In addition, the tip of a tubular body having a material similar to a sphere and a thickness of 0.05 to 0.5 mm and an inner diameter of 0.5 to 3 mm is inserted into the through-hole of the coated body and fixed to the joint. It is a liquid applicator.

In the present invention, the application body is preferably composed of a plurality of spheres .

In the present invention, it is preferable that an annular spacer made of an elastic material is attached between a plurality of application bodies .
In the present invention, it is preferable that the periphery of the discharge port on the front end surface and the rear end surface of the application body is formed into a flat surface.

  In the present invention, it is preferable that the coated body is made of a metal having a high thermal conductivity material and the portion is formed by pressing.

  According to this, mass productivity can be secured without variation in accuracy by forming the coated body by press working. In particular, if you press (perforate) from the surface (the side that contacts the skin), the edge of the hole becomes R (curved surface) and the burrs come inward, so post-processing such as deburring after processing It can be made unnecessary.

  In the present invention, it is preferable that at least the surface of the coated body has a thermal conductivity of 1 W / m · K or more.

  According to the present invention, by using a high thermal conductivity material such as metal on at least the surface of the application body, a suitable application feeling such as “cool feeling” at the time of application can be given to the user.

The application liquid stored in the storage portion 12 of the shaft body 10 is pushed out toward the application body 14 by the feeding mechanism 16 and is discharged from the discharge port 14a of the application body 14.

  The application body 14 has a discharge port 14a at the tip, and at least the surface of the application body 14 and the periphery of the discharge port 14a are made of metal. In the embodiment, the application body 14 provided at the tip of the front shaft 28 is made of a metal having a high thermal conductivity material.

  More specifically, the liquid applicator includes an applicator body 14 that is an outer cylinder, a shaft body 10, a tip shaft 28, a joint 30, a feeding mechanism 16, and a cap 10b as main members.

In this liquid applicator, the application liquid such as fluid cosmetics in the housing portion 12 of the shaft main body has a viscosity of 0.3 Pa · sec at 25 ° C. and a shear rate of 5 sec ⁻¹ in the embodiment. It is in the range of 50 Pa · sec.

The shaft body 10 has a substantially hollow cylindrical shape, and a tip portion 10a thereof is tapered, and the outer diameter of the tip portion 10a is formed substantially the same as the inner diameter of the cap 10b. A cap 10b is detachably fitted to the tip portion 10a. A rib-like uneven portion is formed at the mutually facing portion of the tip portion 10a and the cap 10b set at the time of mounting, and the cap 10b is inadvertently forced against the tip portion 10a so that the protrusions and recesses fit with each other. It is designed not to come off. By preventing the cap 10b from being removed from the shaft body by an unexpected force, the airtightness can be improved, and volatilization of the coating liquid around the application body 14 can be prevented.

  From the opening of the tip portion 10a of the shaft body 10, the rear portion of the tip shaft 28 is fitted in a liquid-tight manner in a state where the joint 30 is arranged inside the substantially cylindrical tip shaft 28. The application body 14 is fixed to the tip of the tip shaft 28 so as to close the opening. Further, the flange-like portion of the rear end portion of the joint 30 is brought into contact with the rear end portion of the front shaft 28 fitted to the inner peripheral surface of the tip portion 10a of the shaft body 10 and is prevented from coming off.

  A feeding mechanism 16 is disposed at the rear end of the shaft body 10. The piston body 18 of the feeding mechanism 16 is inserted from the rear end opening of the shaft body 10 and is slidably provided in close contact with the inner wall of the central portion of the body. Further, a space portion surrounded by the inside of the shaft main body 10, the rear end portions of the front shaft 28 and the joint 30, and the front surface of the piston body 18 is formed as a coating liquid containing portion 12.

  A ratchet is formed in the meshing portion 34 between the fixed cylindrical body 24 and the rotation operation member 22 (the front outer peripheral surface of the inner cylinder member 26). The rotation operation member 22 is rotatable in both directions with respect to the fixed cylindrical body 24 (the shaft body 10 on which the rotation operation member 22 is fixed), but rotated in one direction for discharging the liquid cosmetic as the coating liquid. In some cases, the finger is ejected while generating a click feeling in the ratchet, and the rotation is restricted when the finger is rotated in the other direction.

  With respect to rotation restriction, when a torque exceeding a certain level is applied between the outer cylinder cap 32 and the inner cylinder member 26, which are parts of the rotation operation member 22, a torque limiter function is provided to release the restriction and enable rotation. It is possible to prevent damage to the feeding mechanism. That is, the feeding mechanism 16 retreats the piston body 18 by rotating the rotating operation member 22 in the other direction or the like to provide a function of reducing the coating liquid in the housing portion 12 of the shaft body 10, thereby providing the feeding mechanism. After 16 stops the pressurization of the coating solution, the coating solution can be depressurized by the feeding mechanism 16, and a lip or the like in which bacteria hardly propagate from the discharge port 14a of the coating body 14 into the coating solution circulation hole 30a in the joint 30.
