"Problems to be Solved by the Invention" According to the dispensing container, a liquid cosmetic such as a cream foundation can be stored in a normal compact container like a solid cosmetic. However, even with such a container, there are still problems to be solved, such as the following.

When the liquid foundation discharged onto the partition 3 is soaked into the puff 9, the amount discharged from the discharge port 3a is directly scooped by the puff 9, so that the liquid foundation is applied to only one part of the puff 9. Cannot be applied.

Therefore, depending on the usage situation, if the amount of discharge at one time is small, it may be troublesome to repeat the discharge and application operations. In addition, when the amount to be dispensed at one time is large, it is troublesome to apply the amount applied to a part of the puff 9 and spread it evenly around the area.

In this way, not only is the usability poor, but also the puff 9 directly touches the valve body 15a of the outer valve 15 during application.
The valve body 15a is easily damaged due to contact with the valve body.

Furthermore, as shown in FIG. 10, the liquid foundation discharged from the outer valve 15 is discharged toward the opening of the valve body 15a, making the application operation difficult.

This invention aims to effectively solve the problems in the prior art.

For example, it is made of nylon mesh or cloth. In order to prevent the mesh body 23 from coming off, there are
A presser ring 25 bent inward and having an inverted L-shaped cross section is attached by an undercut connection or the like.

Note that it is possible to arbitrarily set the discharge area of the fluid by changing the size of the diffusion mechanism 20.
