Description

[Detailed description of the invention] "Industrial Application Field" The present invention relates to a makeup brush having a container body containing a cosmetic liquid.

"Prior Art" Conventionally, a container containing a cosmetic liquid and a makeup brush for applying the cosmetic liquid have been formed separately.

``The problem that the invention attempts to solve'' Recently, stationery that combines a liquid container and a brush has become known. Makeup brushes are also convenient to use if they are configured in this manner. The proposed makeup brush is designed so that when the upper member, on which the base end of a water-absorbing application part such as a brush tip is implanted, is moved up and down, the internal fluid of the container is sucked up into the application part, and the makeup brush can be held upside down or sideways. The structure is simple so that it can be used in any orientation and prevents liquid leakage.

"Means for Solving the Problem" The lower end surfaces of the upper and lower trunks 2 of the same diameter are opened, and the sliding plate 5 is fit into the lower part of the trunk in a watertight manner so as to be able to rise, and the opening is opened from the upper end of the trunk. A cosmetic liquid container main body 1 with a neck 4 erected, and a small cylindrical part 9 with a suction valve 8 fitted in the mouth and neck in an airtight manner,
A holding cylinder 7 with a cylinder is formed in the cylinder part 12 at the lower part of the support cylinder part 11 that stands up from the upper end of the small cylinder part, and the engagement cylinder part 13 is formed in the upper part, and the support cylinder part 11 is formed upwardly in the support cylinder part 11. It consists of an actuating member 20 into which the sliding cylinder part 18 is fitted so as to be biased and movable up and down, and a water-absorbing coating part 22 is made to stand upward from the top wall part 17 at the upper end of the sliding cylinder part. The actuating member 20 includes an upper member 23 having a peripheral wall 21 suspended from the periphery of the top wall 17, an upper cylinder part fitted into the peripheral wall, an upward valve seat 24 provided on the inner surface of the cylinder part, and a lower end of the cylinder. A cylindrical member 26 formed into a cylindrical piston 25
Then, the elastic plate part 29 is suspended from the lower surface of the plug part 28 with the through hole 27 fitted to the upper end of the cylindrical member, and the discharge valve body 31 attached to the lower end of the elastic plate is brought into pressure contact with the valve seat to discharge. Discharge valve member 34 forming valve 32
The inside of the cylinder is communicated with the base end of the water-absorbing coating part 22 implanted in the top wall 17 of the upper member through the discharge valve and the through hole 27, and the supporting cylinder part 1
1 and the actuating member 20 are provided with engaging means to prevent the actuating member from being pulled out.

"Operation" When the cap 36 is removed and the upper member 23 is pushed down, the pressure inside the pressurizing chamber 35 becomes high because the suction valve 8 and the discharge valve 32 are closed, and then the discharge valve 32 opens and the The liquid in the pressurized chamber is absorbed into the water-absorbing coating portion 22 through the hole 27 . The discharge valve closes due to the elimination of high pressure caused by liquid discharge, and when the upper member 23 is released, the actuating member 20 is biased by the spring 19.
is pushed up, and due to this rise, the pressure inside the pressurized chamber becomes negative, and the liquid inside the container is sucked up through the suction valve 8, and the sliding plate 5 rises due to the negative pressure inside the container due to the suction of the liquid, Eliminate that negative pressure. Cosmetic liquid is applied by rubbing the water-absorbent application part 22, and by pushing down and raising the upper member again, the cosmetic liquid is replenished to the application part.

“Embodiment” First, a first embodiment shown in FIGS. 1 and 2 will be described. A container body 1 has a body portion 2 having the same diameter on the upper and lower sides and an opening on the lower end surface. is standing up. A sliding plate 5 is fitted in the lower part of the body part in a watertight manner so as to be able to rise, and a cosmetic liquid 6 is filled in the body part above the sliding plate.

7 is a holding cylinder with a cylinder, and a support cylinder part 11 is connected from the upper end of the small cylinder part 9 with the suction valve 8 fitted in the neck part through the outward flange-shaped part 10 placed on the upper end surface of the mouth neck part. The cylinder part 12 is formed below the supporting cylinder part, and the engaging cylinder part 13 is formed above the supporting cylinder part, and the engaging cylinder part is formed to have a larger diameter than the cylinder part. Further, from the upper end of the engaging cylinder part, the covering cylinder part 1 is connected via the outward flange part 14.
5 is made to hang down, and the cylindrical portion is fitted onto the outer surface of the container main body body portion 2. Incidentally, an engaging protrusion 16 is provided around the middle and slightly above the engaging cylinder portion.

A sliding cylinder part 18 that is vertically disposed from the top wall part 17 is fitted into the support cylinder part 11 so as to be able to move up and down while being urged upwardly by a spring 19, and an operating member 20 is attached thereto. be.

The actuating member has a peripheral wall 21 hanging from the periphery of the top wall 17 and a water-absorbing coating part 22 in the center of the top wall.
A cylinder having an upper member 23 with its base end implanted, an upper cylinder part fitted into the circumferential wall 21, an upward valve seat 24 provided on the inner surface of the cylinder part, and a lower end of the cylinder formed into a cylindrical piston 25. Two elastic plate parts 29, 29 are suspended from the lower surface of the member 26 and the plug part 28 with a through hole 27 fitted to the upper end of the cylindrical member with an appropriate gap, and a curved part is provided in the middle of the elastic plate part. The parts 30, 30 are arranged in a ring shape, and a discharge valve body 31 is attached to the lower end of the elastic plate, and the valve body is brought into pressure contact with the valve seat 24 to form a discharge valve 32. Further, a valve stem 33 is inserted from the valve body. It is formed by a discharge valve member 34 that hangs down.

A protrusion 21a is provided around the outer periphery of the lower end of the upper member peripheral wall, and the protrusion 21a is engaged with the lower surface of the engagement protrusion 16 described above to prevent the upper member 23 from being pulled out from the engagement cylinder portion 13. I'm letting you do it. A protrusion 26a is also circumferentially provided on the outer surface of the intermediate portion of the cylindrical member 26, and a coil spring 19 is loosely fitted on the outer surface of the cylindrical portion below the ridge, and the lower end of the spring is connected to the upward step on the inner surface of the lower end of the engaging cylindrical portion 13. , engaging the upper end of the spring with the lower surface of the protrusion 26a,
When the upper member 23 is pushed down, the cylindrical piston 25 descends inside the cylinder, pressurizing the inside of the pressurizing chamber 35 formed by the space between the suction valve 8 and the discharge valve 32, and this pressurization causes the elastic plate 29 to become elastic. The discharge valve 32 opens against this, and the liquid in the pressurized chamber is supplied into the water-absorbent application section through the through hole 27 and the pipe 22a. Shoben stick 3
3 prevents the ball valve forming the suction valve 8 from rolling outward from the valve chamber. Reference numeral 22b is a tube made of multiple bristles that forms a water-absorbing coating portion.

"Effects of the Idea" This idea has the above-mentioned structure, and has a suction valve and a discharge valve, and the liquid in the container body is supplied to the water-absorbing coating part of the actuating member by the vertical movement of the actuating member. Since it is provided with a discharge valve, there is no possibility of so-called dripping due to too much liquid as would be the case if the application part is directly placed in the liquid, and since it is equipped with a discharge valve, the makeup brush can be tilted or held upside down. Since the upper and lower parts of the container body have the same diameter, and the sliding plate is fitted watertightly into the lower part of the same part, negative pressure due to decrease of liquid inside the container body can be avoided by raising the sliding plate. This eliminates the need for an outside air inflow hole into the container body as in the case of a normal container, making it possible to prevent liquid leakage or vaporization from the inflow hole, and to prevent the operating member from leaking or vaporizing. Since the structure is simple, the cost can be reduced even though it is a pump type.
