Description

[Detailed explanation of the idea] "Industrial application field" This case concerns a makeup brush containing makeup liquid.

``Prior Art'' Conventionally, cosmetic liquids were placed inside a container, and makeup brushes were hung inside the container from a cap that fitted into the container.

``Problems that the invention attempts to solve'' The conventional makeup brushes described above require the cap to be removed from the container body and the brush attached to the cap to be used, which is cumbersome, and the container is left with the cap removed. There was a risk that the body would fall and the stored liquid would spill out.

This design has a cosmetic liquid inside the brush itself so that an appropriate amount of cosmetic liquid can be applied to the tip of the brush with a simple operation, making it easy to apply makeup.

"Means for Solving the Problems" The cosmetic brush of the present invention consists of a container body, a pump part, a brush barrel, and a member with a pipe.

The container body 1 has an elongated cylindrical shape with a neck portion 2 erected upward.

The pump section 5 has a nozzle 6 erected in an upwardly biased state from a body section that is watertightly fitted into the mouth of the container body, and pushes down the nozzle against the bias to pump the inside of the body section. The liquid in the pressurized chamber is ejected from the upper end of the nozzle, and the liquid in the container is sucked into the pressurized chamber when the nozzle is raised by pressing down and releasing the nozzle.

The brush barrel 15 has a brush tip 17 protruding upward from the upper end of the barrel barrel 16 into which the pump-equipped container body is inserted, and the lower end of the container body is suspended below the lower end of the barrel barrel. be. Member with pipe 2
0 is fitted into the cylindrical part between the lower end of the brush tip and the upper end of the nozzle. The lower end of the pipe 21 of the piped member is communicated with the nozzle, and the upper end of the pipe is led out into the middle part of the brush tip 17.

By pressing down the lower end of the container body relative to the brush barrel 15, the nozzle can be pressed down relative to the container body.

"Operation" When the nozzle 6 is pushed down relative to the brush barrel 15 by pushing down the lower end of the container body, the liquid in the pressurized chamber of the pump section is ejected from the upper end of the nozzle, and the ejected liquid flows through the pipe 21. Since it is led out into the middle part of the brush tip 17, the brush tip absorbs the lotion. When the push-up of the lower end of the container body is released, the pump part and the container body are lowered relative to the brush barrel due to the elasticity of the spring that biases the nozzle, and return to their original positions.

"Embodiment" The container body 1 has a mouth and neck part 2 erected upward from the upper end of an elongated cylindrical body via a shoulder part. A lid 4 with a small through hole 3 is fitted to the lower end of the body to close it off. A sliding partition plate 4a is fitted into the lower part of the body, and a liquid chamber is formed in the container body above the plate, and an air chamber is formed in the lower chamber.

The body of the pump section 5 is fitted into the mouth of the container body. In the pump section, the nozzle 6 is urged upward to stand up, and when the nozzle is pushed down against the nozzle urging, the liquid in the pressurized chamber is ejected from the upper end of the nozzle. It is provided so that the liquid inside the container is sucked into the pressurized chamber, and may be formed almost in the same way as a pump part used in a pressure accumulation type manual sprayer. 7 is a small diameter cylinder, 8 is a communication pipe with cylindrical pistons at both upper and lower ends, 9 is a presser cylinder, 10 is a large diameter cylinder, and a nozzle 6 is connected from the upper end of the cylinder via an inward flange.
is standing up. 11 is a suction valve, 12 is a discharge valve, and when the insides of both cylinders are pressurized by pressing down the nozzle, the valve rod 14 resists the bias of the spring 13.
The connecting pipe is pushed down by the diameter difference between the two cylinders, the discharge valve opens, and the liquid in both cylinders is spouted out. When the pressurized state is released and the discharge valve closes, and the nozzle rises, the communication pipe also rises, and the suction valve 11 opens due to the negative pressure in both cylinders, sucking in the liquid inside the container.

The container body with the pump portion is inserted into the writing barrel 15. The brush barrel has a brush tip 17 projecting upward from within the upper end of the barrel barrel portion 16, and the lower end of the container body is suspended below the lower end of the barrel barrel. A cover 18 is fitted over the portion of the brush tip except for the lower part and the lower end surface. An O-ring 19 is fitted between the outer surface of the presser tube 9 and the inner surface of the shaft tube portion 16.

A member with a pipe 20 is fitted in the shaft tube between the lower end of the brush tip and the upper end of the nozzle, and the lower end of the pipe 21 is communicated with the upper end of the nozzle, and the upper end of the pipe is led out into the middle part of the brush tip 17. ing.

In the above configuration, when the lower end of the container body is pushed up against the brush barrel, the lower part of the pipe-equipped member 20 together with the large-diameter cylinder 10 with a nozzle is pushed into the presser cylinder 9, and thus the pump section is pressurized as described above. The chamber liquid is squirted into the tip.

22 is a cap provided as necessary.

"Effect of the invention" The pump section is activated by pushing up the bottom of the container, and the cosmetic liquid in the pressurized chamber inside the pump section squirts into the middle part of the brush tip through the pipe 21 and wets the brush tip. Impregnation with liquid can be carried out easily and quickly.
