Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a liquid container with a makeup brush that contains a liquid cosmetic and is equipped with a flat makeup brush.

``Prior art'' Conventionally, this type of makeup brush is used by inserting a separate makeup brush into a liquid pot each time you apply makeup, or by using a container shaped like a pencil and attaching a makeup brush to one end. Alternatively, there are devices that supply cosmetic liquid when needed.

``The problem that the invention seeks to solve'' In the conventional method, the former is time-consuming to use;
It is also inconvenient to carry, and in both methods, the makeup brush is attached directly to the liquid part.
Difficult to prevent dripping.

By the way, a flat brush is a convenient makeup brush that is used for drawing in both wide and narrow widths, but this flat brush has a liquid channel in the center of the round brush tip 51, as shown in an example in Fig. 2. A cylinder core 52 is provided, and the outer surface of the lower half of the brush tip 51 is held down by a metal jacket cylinder 53.
It is formed by crushing the upper part of the plate into a flat plate. On the other hand, since the diameter of the opening of the mounting part of the cylindrical brush shaft to which the flat brush is attached is small, it is not possible to set the flat brush inside in advance. In this case, screw it on to prevent it from slipping out. For this reason, a cylindrical screw shaft 54 shown in FIGS. 2 and 3 is provided on the brush side, and a threaded tube into which this screw shaft 54 is screwed is installed on the brush shaft side. As the number increases, the cost increases.

The present invention includes a cylinder closed with a valve,
The structure is such that a constant, appropriate amount of cosmetic liquid is supplied from this cylinder at the required time by push-button operation, and therefore, it is extremely easy to handle, does not leak, is convenient to carry, and can be directly attached to a flat brush without using any attachment parts. It is possible to obtain a liquid container with a makeup brush.

"Means for Solving the Problems" The liquid container with a makeup brush of the present invention has a straight cylindrical body 7, and a bottom lid 8 that can be lifted up is liquid-tightly provided at the bottom of the body 7. 1, a cylinder 2 whose lower half is fitted inside the mouth and neck part 9 of this container body 1 and protrudes upward, and has a suction valve 10 installed in its lower part; The brush shaft 3 extends upward and has a downwardly facing stepped portion 11 on its upper inner surface, and the outer surface of the lower half of the brush tip 12 is held down by a metal jacket tube 13, and a large diameter portion 14 at the bottom of this jacket tube 13 is attached.
is fixed to the downward step part 11 and set in the opening of the brush shaft, and after setting, the flat brush 4 is formed by crushing the upper part of the outer cover tube 13, and the upper end is fixed to the inner surface of the upper part of the brush shaft 3, A cylinder whose lower end is formed as a cylindrical piston 15 inscribed in the cylinder 2, and an upwardly stepped valve seat 16 is formed on the inner circumferential surface of the intermediate part, and which is urged in a direction away from the cylinder 2 by a return spring 17. A member 5 with a piston in the shape of
Alternatively, a valve body 20 is fixed to the inner surface of the piston-equipped member 5 and has an elastic compression plate portion 18 hanging therefrom, and a valve body 20 is pressed against the valve seat 16 below the plate portion 18 to form the discharge valve 19.
A member 6 with a valve body is provided.

"Operation" In the above, the brush shaft 3, the member with the piston 5, and the member with the valve body 6 are normally pushed up to the upper limit by the return spring 17, and the cylinder 2 is filled with the cosmetic liquid sucked in by the suction valve 10. are doing.

When applying makeup, the cap 21 is removed and the combination of the container body 1 and the cylinder 2 is pushed up against the return spring 17 (or the brush shaft 3, the member with the piston 5, and the member with the valve body 6 are pushed down). Then, since the cosmetic liquid in the cylinder 2 is pressurized, this pressurized cosmetic liquid pushes the lower part of this plate part 18 upward by the elastic compression plate part 18 of the member with a valve body 6, and the discharge valve 1
Since the valve 9 is opened, the cosmetic liquid is supplied to the flat brush 4 through the compression plate part 18. This supply creates a negative pressure inside the cylinder 2, so the suction valve 10 opens and the cosmetic liquid inside the container body 1 is sucked into the cylinder 2.
In response to this, the bottom cover 8 moves upward.

"Embodiment" A push button 22 for pushing operation is fixed to the lower end opening of the container body 1 so as to protrude downward. This push button 22 has an upright shaft 23 in the center and a breather hole 24 in a part thereof. The bottom plate 8 has a circumferential edge formed into an elastic peripheral wall 25 having an arcuate cross-section, and this elastic peripheral wall 25 is brought into pressure contact with the inner surface of the body 7, and is internally installed in a liquid-tight manner so as to be able to rise.

The cylinder 2 has an outward flange 26 on the outer surface of the intermediate portion that is engaged with the top surface of the mouth of the container body, and a lower half that is fixedly fitted into the mouth and neck portion 9 by the rough surface, and a return spring 17 on the inner periphery of the upper end. Upward step 2 as a support part
The suction valve 10 forming part 7 has a check valve function, and although a ball valve is shown in the figure, this may also be an elastic plate-shaped valve with a tongue-shaped valve portion cut into an elastic plate.

The brush shaft 3 has a tapered shape at the top, and by making the upper end thicker inward, there is a downward step 1 on the inner surface of the upper part.
1 is formed.

The flat brush 4 has a cylindrical core 28 inserted into the shaft core of a round brush tip 12 with its lower part protruding downward, and the lower half of the brush tip 12 is expanded in diameter to the large diameter section 14 at the lower end. The large diameter part 14 is fixed to the downward stepped part 11 at the opening of the brush shaft 3 in advance, and the upper half is pushed outward to set the interior. , is formed into a flat brush by crushing the outwardly protruding portion of the jacket tube 13. Note that the flange-shaped portion 29 at the lower end of the writing shaft 12 is formed by hardening with adhesive or the like.

The piston-equipped member 5 is fitted and fixed to the brush shaft 3 with an appropriate gap between it and the lower end of the flat brush 4 by means of an outward flange 30 at the upper end, and the diameter of the lower half is reduced inward in a stepped shape. The cylindrical piston 15 at the lower end has elasticity and comes into liquid-tight pressure contact with the inner surface of the cylinder 2, and the outward flange 30 and the upward step at the upper end of the cylinder 2 It is constantly pushed upward by a return spring 17 disposed between 27.

The member with a valve body 6 is fixed by attaching an outward flange 32 protruding from an upper end cylindrical portion 31 communicating with the cylindrical core 28 of the flat brush 4 between the lower end of the flat brush 4 and the upper end of the member with a piston 5. A shaft 33 is provided which hangs down the cylinder's two-axis core part through the elastic compression plates 18, 18 on both sides curved from the upper end cylinder part 31, and an outward flange is provided from the upper part of this shaft 33 to press the valve seat 16 from above. A valve body 20 having a shape is provided. The shaft 33 adjusts the internal volume of the cylinder 2, and
During the return operation, the lower end serves to push down the suction valve 10 and forcibly return it.

The cap 21 is fitted onto the outer surface of the brush shaft 3.

Reference numeral 34 denotes an external cylinder whose upper part is fitted onto the outer surface of the lower part of the pen shaft 3, and has an inward flange 35 on the inner circumferential surface near the upper part that locks the outward flange 26 of the cylinder 2, and which is connected to the outer surface of the container body 1. A narrow gap is provided between them. A notch 36 is provided on one side of the lower end of this external cylinder 34.
The push button 22 is pressed using this notch 36.

In the embodiment described above, the cylinder 2 is set to have a volume that accommodates an appropriate amount of liquid sufficient for the flat brush 4 but not excessive. Each part is molded from synthetic resin except for the return spring 17 and the jacket tube 13.

"Effect of the invention" In the above invention, a cylinder 2 is provided separately in addition to the container body 1, and the cosmetic liquid is supplied from the cylinder 2 to the flat brush 4 when necessary. Container body 1 with discharge valve 19,
Since it has a structure that is constantly disconnected from the flat brush 4, there is no fear of liquid dripping to the outside. Further, since the overall shape is a pencil shape, it is suitable for portable use, and the operation is one-touch, by pressing the bottom of the container body 1 via the push button 22, which is simple and hassle-free.

Since the flat brush 4 is crushed after being set on the brush shaft 3 in a round shape, it can be directly attached to the brush shaft 3, and therefore there is no need to use a cylindrical shaft 54 or a screw tube for attachment. This reduces the number of parts and costs.
