Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a liquid container with a makeup brush for storing liquid cosmetics such as eyebrow ink and liquid lipstick.

``Prior Art'' Many conventional devices of this type have a pencil-shaped container, a makeup brush is attached to one end, and cosmetic liquid is supplied to the makeup brush at all times or when required.

``Problems to be solved by the invention'' In any of the above conventional methods, the makeup brush is attached directly to the liquid part, making it difficult to prevent the liquid from dripping. Taking this into consideration, the container is handled in an upright position with the mouth facing upward.

The present invention has a reservoir chamber that is closed with a valve, and a certain appropriate amount of cosmetic liquid is supplied from this reservoir chamber when required.
To obtain a convenient liquid container with a makeup brush that can be handled upside down.

"Means for Solving the Problems" The liquid container with a makeup brush of the present invention has a straight cylindrical body 7, and an operating rod 8 can be pushed into the axis of the body 7 from the bottom opening. A container body 1 is provided with a donut-shaped bottom lid 9 that can be raised and lowered in a liquid-tight manner between the operating rod 8 and the body 7, and the lower part is fitted onto the outer surface of the neck part 10 of the container body 1. A brush holding cylinder 2 which extends upward and has a makeup brush 11 attached to its tip opening; and a valve cylinder 3 which is fitted and fixed to the brush holding cylinder 2 and has an engaging protrusion 12 for a valve on its inner peripheral surface. The upper end is fluid-tightly inscribed in the valve cylinder 3, the lower end provided with a split groove 13 is in contact with the tip of the operating rod 8, has a suction valve 14 inside, and is always urged downward by a return spring 15. The movable cylinder member 4 forms a storage chamber A with the valve cylinder 3, and is fixed to the inner surface of the brush holding cylinder 2 through an upper outward flange 16 provided with a communication path to the makeup brush 11 to form a storage chamber A. The axial core part hangs downward, and an engaging protrusion 18 is provided on the outer surface of the shaft midway to join the engaging protrusion 12 from above to form the discharge valve 17. formed in the elastic part 19, and this elastic part 1
It is composed of a valve shaft 5 whose lower part is movable in the vertical direction, and a cap 6 which is fitted and attached to the outer surface of the brush holding cylinder 2.

"Operation" In the above, the movable cylinder member 4 is normally pushed down to the lower limit by the return spring 15, and the storage chamber A is filled with the cosmetic liquid sucked in by the suction valve 14.

Here, when applying makeup, the cap 6 is removed and the operating rod 8 is pushed upward against the return spring 15 to push up the movable cylinder member 4. Then, since the cosmetic liquid in the storage chamber A is pressurized, this pressurized cosmetic liquid pushes the lower part of this ring 19 upward by the elastic ring 19 of the valve shaft 5 and opens the discharge valve 17, so that the cosmetic liquid It is supplied to the makeup brush 11 through the communication path of the flange 16. This supply creates a negative pressure in the storage chamber A, so the suction valve 14 opens, the cosmetic liquid in the container body 1 is sucked into the storage chamber A, and the bottom cover 9 moves upward accordingly. Incidentally, during the return operation, the lower end of the valve shaft 5 pushes down the suction valve 14 to forcibly return it.

“Example” A thread 20 is formed on the outer surface of the neck portion 10 of the container body 1, and a ventilation groove 2 is formed on the lower end opening of the body portion 7 by a rough surface.
1 is fixed. In addition, a cylindrical portion 2 inscribed in the presser tube 22 is provided at the lower end of the operating rod 8.
23 is formed so as to protrude downward, and an outward flange 2 is formed at the upper end of this cylindrical portion 23 and is engaged with the upper end of the presser cylinder 22.
4 to prevent it from slipping out. The bottom cover 9 has an inner and outer peripheral edge formed into an elastic part having an arc-shaped cross section.
This elastic part is brought into pressure contact with the inner surface of the body 7 and the outer surface of the operating rod 8, and is internally installed in a liquid-tight manner and movable up and down.

The brush holding cylinder 2 has the container body mouth neck 1 on the inner periphery of the lower part.
A screw groove is formed to be screwed into the screw thread 20 of 0, and a screw thread 25 is formed on the outer periphery of the upper part. The makeup brush 11 has a cylindrical core 26 inside the shaft core to form a hollow part for introducing cosmetic liquid, and the outer surface excluding the tip of the brush is pressed with a cylindrical brush holder 27, and the makeup brush 11 and the brush holder 27 are combined. The lower end is shaped like an outward flange, and this lower end is attached to the opening of the brush holding cylinder 2 using a downward step so as not to be pulled out.

The valve cylinder 3 is fitted and fixed in the brush holding cylinder 2 with an appropriate gap between it and the lower end of the makeup brush 11, and the opening member 28 is fitted inside the mouth top of the container body neck 10 at its lower end. is fixed with a presser foot.

The movable cylinder member 4 has a thin elastic part 30 at its upper end, which is brought into pressure contact with the inner surface of the valve cylinder 3 to make it liquid-tight, and a downward step is formed on the outer periphery of the upper part, and this step is connected to the top of the mouth member 28. to determine the lower limit position,
Further, the return spring 15 is disposed between the upper inner surface and the engagement protrusion 12 of the valve cylinder 3, and split grooves 13 provided in the small diameter portion of the lower end are formed at various locations in the circumferential direction. The suction valve 14 has a check valve function, and although a ball valve is shown in the figure, it may also be an elastic plate-shaped valve in which a tongue-shaped valve portion is cut into an elastic plate.

The valve stem 5 connects the outward flange 16 at the upper end to the valve cylinder 3.
It is attached between the upper end and the lower end of the makeup brush 11, and the flange 16 is provided with several through holes 31 in the circumferential direction as communication paths.

The cap 6 has a thread formed on the inner periphery of the intermediate portion to be threadedly engaged with the thread 25, and also has the brush holder 27 inside.
An inner cap 32 is formed to fit on the outer surface, and is doubly fitted.

In this embodiment, the reservoir A is sized to accommodate an appropriate amount of liquid sufficient for the makeup brush 11, but not excessive. In addition, each part except the return spring 15 is molded and manufactured from synthetic resin material.

"Effect of the invention" In the above invention, a storage chamber A is provided separately in addition to the container body 1, and the makeup liquid is supplied from this storage chamber A to the makeup brush 11 when necessary. Container body 1 and makeup brush 1 with valve 14 and discharge valve 17
1 has a structure that is always closed, so there is no fear of liquid dripping to the outside, and therefore, this liquid container can be placed either upright or upside down, making it inconvenient to handle. It is suitable for portable use. In addition, since the movable part is only the movable cylinder member 4, which is a small part, there is an advantage that the return spring 15 can be small.
It's simple and hassle-free.
