The application body is composed of a chip having a through-hole that can communicate with the tank chamber, and a ball that is rotatably supported at the tip of the through-hole of the chip and a part of which protrudes from the tip of the chip. Thus, the liquid cosmetic is exuded from the gap between the ball and the inner wall surface of the through hole of the chip by rolling of the ball, and is used for application.

  According to a second aspect of the present invention, in the first aspect of the present invention, the chip is made of plastic, and the ball is made of ceramics.

  According to a third aspect of the present invention, in the first or second aspect of the present invention, a guiding member is provided between the tank chamber and the ball so that the liquid cosmetic can permeate through the liquid cosmetic. It is characterized by being able to.

  According to a fourth aspect of the present invention, in the invention according to any one of the first to third aspects, the liquid cosmetic overflowed when an external pressure is applied to the tank chamber and the liquid cosmetic overflows from the tank chamber. A storage part to be stored is provided between the tank chamber and the application body, and a large number of fins are formed in the storage part, and an interval between adjacent fins is set to 0.1 mm to 0.2 mm. It is characterized by that.

  According to the present invention, the liquid cosmetic is exuded using the rolling of the ball, so that the coating width is controlled to be constant according to the diameter of the ball without being affected by the force applied. be able to.

  Therefore, since it can be used without worrying about the amount of force applied, it is easy to use and a fine makeup work can be easily performed.

It is the whole liquid cosmetics application container concerning an embodiment of the present invention longitudinal section. It is the elements on larger scale of FIG. It is a longitudinal cross-sectional view showing the state which removed and used the cap of the liquid cosmetics application container of FIG.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 represents an embodiment of the present invention. As shown in the figure, a liquid cosmetic application container 10 according to the present invention includes a rear cylinder 12 that is held by a user and in which the liquid cosmetic is accommodated. The rear part of the front cylinder 14 is press-fitted into the rear cylinder 12 from the front.

  The front tube 14 has a flange portion 14a formed on the outer peripheral surface thereof, and a rear portion of the front tube 14 is inserted into the rear tube 12 from the front side. The rear end of the front cylinder 14 is closed by a tail plug 16, whereby a tank chamber 17 is formed by the front cylinder 14 and the tail plug 16, and liquid cosmetic is stored in the tank chamber 17. As the liquid cosmetic, a pigment aqueous ink containing a pigment such as an eye liner can be used. The viscosity can be about 2-20 cp. Liquid cosmetics are not limited to liquids, and may be gel cosmetics with thixotropic properties. A ball 19 for agitating the liquid cosmetic is disposed in the tank chamber 17.

  The front portion of the front tube 14 is a tapered portion that gradually decreases in diameter toward the front, and the front end of the front tube 14 defines a tip opening 14b.

  The rear cylinder 12 and the front cylinder 14 constitute a shaft cylinder. Although the front cylinder 14 and the rear cylinder 12 are separate parts, they can be formed as an integral part, and the liquid cosmetic may be directly stored in the rear cylinder 12.

  An adjuster cylinder 18 having a storage portion 18a for storing the liquid cosmetic overflowing from the tank chamber 17 is inserted in front of the front cylinder 14. An annular protrusion 14 c is formed on the inner peripheral surface of the front cylinder 14, and the adjuster cylinder 18 is fixed in the front cylinder 14 by fitting the annular protrusion 14 c into an annular groove 18 b formed in the adjuster cylinder 18. Is done. The storage groove 18a has a large number of fins 18d in a bellows shape, and can hold the liquid cosmetic by a capillary force in a gap formed between adjacent fins 18d. Preferably, when the width of the adjacent fins 18d is set to 0.1 mm to 0.2 mm, an appropriate capillary force can be exhibited.

  A relay core 20 as a guiding member passes through the through hole 18e of the adjuster cylinder 18. The rear end portion of the relay core 20 extends rearward from the rear flange portion 18 c of the adjuster cylinder 18 and projects into the tank chamber 17. The relay core 20 can be composed of a fiber core made of polyethylene, polypropylene, polyester, or the like, and the liquid cosmetic is guided by infiltrating the interior of the core into the liquid cosmetic. The cosmetic is guided through the relay core 20 to the front. As shown in FIG. 2, a communication window 18 f for communicating with the storage portion 18 a is formed in the through hole 18 e of the adjuster cylinder 18. For this reason, when an external pressure is applied to the tank chamber 17 and the pressure difference from the outside air increases, a large amount of the liquid cosmetic overflows from the tank chamber 17 into the through-hole 18e of the adjuster cylinder 18, and then the liquid cosmetic. However, it is temporarily stored in the storage part 18a through the communication window 18f by the capillary force, so that the liquid cosmetic can be prevented from overflowing to the outside.

  An application body 22 is provided at the front end opening 14b of the front cylinder 14. The application body 22 includes a chip 24 having a through-hole 24 a and a ball 26 that is rotatably supported at the tip of the chip 24 and a part of which protrudes from the tip of the chip 24. The rear end of the tip 24 of the application body 22 is press-fitted into the tip of the adjuster cylinder 18, and the stepped portion 24 b of the tip 24 abuts on the peripheral surface of the front end opening 14 b of the front cylinder 14. , Fixed to the front tube 14. The front part of the tip 24 than the step part 24b is a tapered part that is gradually reduced in diameter toward the front.

  The tip of the through-hole 24a of the chip 24 is reduced in diameter so as to accommodate and hold the reduced diameter portion 24d in which a plurality of channels 24c are formed on the inner peripheral surface to allow liquid cosmetics to circulate. A ball housing 24e having a diameter larger than that of the diameter portion 24d is provided.

  The front end of the relay core 20 is inserted into the through hole 24a of the chip 24, and the front end of the relay core 20 reaches the reduced diameter portion 24d where it contacts the ball 26 or the surface of the liquid cosmetic. As a distance at which the liquid cosmetic material can be transmitted from the relay core 20 to the ball 26 due to tension or the like, a gap of about 0 to 0.5 mm is set between the tip of the relay core 20 and the ball 26. Preferably, a gap of about 0.01 to 0.1 mm is set. Alternatively, a gap of 0.5 mm or more can be provided depending on the surface tension of the liquid cosmetic. In any case, the through hole 24 a of the chip 24 can communicate with the tank chamber 17 via the relay core 20.

  The chip 24 and the ball 26 can be made of any material including a metal such as stainless steel. Preferably, the chip 24 is made of plastic, and the ball 26 is made of ceramic. When the application body 22 comes into contact, it is preferable because it does not give discomfort and is familiar with the surface to be applied.

  Moreover, the diameter of the ball | bowl 26 can be selected according to a use, for example, when applying to an eyeliner, it is good to set it as about 0.8 mm-1.0 mm.

  In order to protect the application body 22 from drying when not in use, a cap 28 is detachably attached to the front portion of the front tube 14.

  In the liquid cosmetic application container 10 configured as described above, when used, the cap 28 is removed as shown in FIG. 3, and the application body 22 is applied to the surface to be applied and moved. As a result, the ball 26 rolls, passes through the relay core 20 from the tank chamber 17, and liquid cosmetic exudes from between the ball 26 and the inner peripheral surface of the through hole 24 a of the chip 24 as the ball 26 rolls. , Supplied to the surface to be coated.

  When applied to an eyeliner as a liquid cosmetic application container, the surface to be applied is a region around the eyes, and is a non-horizontal and three-dimensionally curved surface. When applying to such a non-horizontal surface, since it is difficult to stably support the hand holding the shaft tube, the pressure applied to the application surface tends to become unstable. On the other hand, since the purpose of the eyeliner is to trim the eyes, it is desirable to apply the eyeliner with a certain width.

  In the application body 22 of the present invention, the application width can be applied to the line width determined by the diameter of the ball 26 regardless of the force, so that the application width is controlled to be constant regardless of the posture of the hand. can do.

  In addition, when applying to a substantially vertical surface such as the area around the eyes or the face, the application body 22 does not face downward, so that the liquid cosmetic in the tank chamber 17 is transmitted to the application body 22. There is a risk of not. However, since the liquid cosmetic material is transmitted to the application body 22 through the relay core 20, the liquid cosmetic material already sucked into the relay core 20 can be supplied from the application body 22, and whether the application is performed or not. Can prevent rubbing and the like.

  Further, in the above example, the guide member is constituted by only the relay core 20, but it is also possible to make a derivative by combining the relay core 20 and the liquid absorbent material. The liquid absorbent material can be composed of a porous elastomer such as a sponge.

  In the above embodiment, the liquid cosmetic is stored directly in the tank chamber. However, the present invention is not limited to this, and the tank is made by absorbing the liquid cosmetic in an absorbent body such as a batting. You may accommodate in a chamber.

  In the above embodiment, a part constituted by a plurality of members can be constituted by a single member, or a part constituted by a single member can be constituted by a plurality of members.
