Description

[Detailed description of the invention] "Industrial application field" The invention relates to a makeup brush that stores liquid cosmetics such as eyebrow ink and liquid lipstick. The present invention relates to a makeup brush configured to supply a fixed amount of makeup to a tip-shaped applicator at a predetermined time.

``Prior Art'' Conventional makeup brushes of this type have a simple pencil-shaped cylindrical barrel that stores cosmetic liquid, and a tip-shaped applicator is attached to the opening at one end, and the cosmetic liquid is applied to this applicator at any time or as needed. There are many systems that supply

``Problem that the invention aims to solve'' In conventional makeup brushes, the applicator part was attached directly to the opening of the barrel barrel, so the applicator part had to be positioned downward during use. When the cosmetic liquid was supplied to the application area, there was a problem in that the liquid dripped due to excessive supply. Furthermore, conventional makeup brushes have been used only in an upright position with the applicator facing upward in consideration of dripping, which has been inconvenient as there is no flexibility in handling them.

The present invention was devised in consideration of these circumstances, and aims to provide a convenient makeup brush that does not drip and can be freely handled in an upright or inverted position.

"Means for solving the problem" In order to achieve the above purpose, the makeup brush of the present invention has the following features:
It has a body part 2 with the same inner diameter on the upper and lower sides and an open lower end surface,
A mouth and neck part 4 is erected from the upper end of the body via the shoulder part 3, and a discharge valve 5 is provided on the inner surface of the middle part of the mouth and neck, and the lid end is fitted into the upper end of the mouth and neck from the upper end of the mouth and neck. A shaft cylinder 1 with an application part 6 erected thereon, a sliding plate 9 fitted into the lower part of the body in a watertight manner so as to be able to rise by creating a negative pressure inside the body, and a lower opening of the discharge valve. The upper end portion is fitted into the cylinder portion 7 formed by the neck portion, and the plunger 11 is fitted into the upper body portion in an upward biased state, and the rod portion 12 projected from the plunger is vertically installed in the upper body portion. The operating part 10 is made to protrude outward through an elongated hole 8, and has an operating plate 13 attached to the tip of the rod, and is formed to be able to be moved up and down via the operating plate.

The plunger portion above the rod and the plunger portion below the rod always make watertight contact with the body portion above the elongated hole and the body portion below the elongated hole, regardless of the vertical movement of the operating portion. A liquid passage 1 which is provided with first and second elastic skirt-like parts 14 and 15 and communicates between the inside of the body above the first elastic skirt-like part and the inside of the body below the second elastic skirt-like part.
6 is provided on the plunger, and by moving the operating portion up and down by the operation plate, the upper end of the plunger pressurizes the inside of the cylinder and is formed to be detachable from the cylinder.

"Operation" As shown in FIG. 1, the operating part 10 is
is urged upward by a coil spring, etc.
The upper end of the plunger 11 is fitted into the cylinder portion 7. That is, communication between the inside of the cylinder section and the inside of the body section 2 is cut off.

When applying makeup, as shown in FIG. 2, after removing the cap, etc., and inverting the barrel 1, the actuating portion 10 is pushed up via the operation plate 13. As a result, the upper end of the plunger separates from the cylinder section 7, and the cosmetic liquid in the body flows into the cylinder section.

After this, the push-up by the operation plate is immediately released. As a result, the actuating portion 10 is pushed down by the urging force of a coil spring or the like, and the tip of the plunger is fitted into the cylinder portion. As a result, the cosmetic liquid in the cylinder section is pressurized, and the pressurized cosmetic liquid pushes open the discharge valve 5 and flows into the application section 6.

At this time, the inside of the body becomes negative pressure due to the outflow of the makeup liquid in the body into the cylinder part, but the sliding plate 1 is lowered due to the negative pressure, and the negative pressure is eliminated.

"Example" The embodiment shown in FIGS. 1 and 2 is the same as that described in "Means for Solving Problems", and to avoid duplication, explanation of the previously described part will be provided. will be omitted and only explanations will be given for matters not already mentioned.

A bottom plate 17 with a breather hole is fitted into the lower end opening of the body 2.

The sliding plate 9 has a peripheral edge formed into an elastic portion 18 having an arcuate cross section, and the elastic portion 18 is pressed against the inner surface of the body.

A disk-shaped spring receiver 19 with a plurality of through holes is fitted into the middle portion of the inner surface of the body 2, and a compression coil spring 20 is interposed between the upper surface of the spring receiver and the lower end surface of the plunger 11. There is.

A holding cylinder 21 is fitted into the lower half of the plunger, and first and second elastic skirt-like parts 14 and 15 are attached to both upper and lower ends of the holding cylinder.

The rod portion 12 and the operation plate 13 are integrally formed, and the tip of the rod portion is fitted into a fitting hole formed in the holding cylinder 21 and the plunger 11.

The liquid passage 16 is vertically provided inside the plunger 11 as a communication hole.

The upper end of the plunger 11 has an elastic skirt-like portion 2
It is formed in 2.

The shoulder section 3 at the upper end of the body is formed in two stages, and the lower part of the cap 24 is fitted onto the outer surface of the cylindrical section 23 between the upper and lower shoulders.

The discharge valve 5 has a check valve function, and a ball valve is used in the figure.

The application section 6 is formed of a water-absorbing fiber rod.

In the above embodiment, each part is a coil spring 20.
It is molded and manufactured from a synthetic resin material except for the application part 6.

"Effects of the Invention" As explained above, according to the present invention, a cylinder part is separately provided outside the body part in which the cosmetic liquid is stored, and the cylinder part is communicated with the body part as necessary, and the pump is pumped from this cylinder part. Since the mechanism supplies a predetermined amount of liquid to the application section when necessary, there is no concern about liquid dripping due to oversupply or liquid leakage due to falling.
Therefore, this makeup brush can be placed either upright or upside down, is convenient to handle, and is suitable for portable use. In addition, the operation is simple and hassle-free, simply by moving the operation panel up and down.
