Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial field of application" The present invention relates to a makeup brush for applying liquid eyebrow, liquid lipstick and the like.

"Prior Art" As the main cosmetic brush, the upper part of the lower cylinder member with the suction valve is fitted in the lower part of the upper cylinder member with the discharge valve so as to be vertically movable and urged downward, and A pump chamber is formed inside, and the upper cylinder member is communicated with the discharge valve through the liquid discharge passage from the upper end of the upper cylinder member, and the mouth and neck is fitted to the lower part of the lower cylinder member to the upright brush. Also known is a so-called knock type in which the liquid inside the container is provided by the pump action (see Japanese Utility Model Laid-Open No. 61-180612).

"Problems to be solved by the invention" By the way, in the container having the above-mentioned configuration, when the container body is pushed up against the brush shaft hanging from the outer surface of the upper tubular member,
Since the liquid in the container (strictly speaking, the liquid in the pump chamber) is discharged to the brush, it is discharged carelessly when the lower end of the container collides with another object, for example, when it is stored inside a handbag or the like. There was a different defect.

Therefore, the present applicant previously proposed a liquid container with a makeup brush equipped with a safety device in Japanese Utility Model Laid-Open No. 62-86114.

This is because the second projecting piece is made to project downward from the lower end of the outer cylinder hanging from the brush shaft, and the outer surface of the lower end of the container body can be relatively positioned and displaced relative to the second projecting piece. Only when the projecting pieces are attached and the facing surfaces of the first and second projecting pieces are displaced, the first projecting piece rises between the second projecting pieces and pushes up the container body against the outer cylinder. Is formed so as to be possible.

However, in such a conventional container, the first projecting piece and the second projecting piece must be displaced from each other before the container is used, and must be aligned after the container is used. The operation was troublesome and difficult to use.

Therefore, an object of the present invention is to provide a makeup brush that is easy to attach and detach the safety device and is easy to use.

[Means for Solving Problems] In order to solve the above problems, the makeup brush of the present invention allows the upper part of the lower cylinder member 2 with the suction valve 24 to move up and down in the lower part of the upper cylinder member 1 with the discharge valve 16. In addition, the pump chamber 3 is formed inside both of these members by fitting them in a downwardly biased state, the brush 46 is erected from the upper end of the upper cylinder member, and at the bottom of the lower cylinder member 2. , A brush shaft hanging from the outer surface of the upper cylinder member 1

And a shutoff valve 56, which is closed by pushing down the brush spikes, is provided between the upper cylinder member 1 downstream of the discharge valve 16 and the brush spikes 46 while supporting the upper cylinder member 1 in a vertically biased state. When the lower part of the peripheral wall is fitted to the outer surface and the brush-cover cap 60 is detachably provided, the brush 46 is pushed down to close the shutoff valve 56.

[Operation] For example, when the cap 60 in FIG. 1 is mounted, the shutoff valve 56 is closed by shutting down the liquid discharge passages 13 and 52 by forcibly pressing down the holding cylinder 49.

As a result, the container body 32 is inadvertently pushed up and the discharge valve 16
Even if the valve is opened, the supply of the liquid in the pump chamber 3 to the brush 46 is blocked.

When the cap is removed from the above state, the shutoff valve 56 is opened by the upward movement of the pressing cylinder and the liquid discharge paths 13 and 52 are communicated with each other.

As a result, the liquid in the pump chamber can be supplied to the brush by the pumping action.
