Description

[Detailed Description of the Invention] The present invention relates to an applicator for a container containing a cosmetic application liquid such as mascara.

A brush is used as the applicator for this type of applicator, but this brush is always immersed in liquid, so when using it, it is necessary to squeeze the liquid contained in the brush to adjust the amount of liquid to the appropriate amount for application. . This squeezing is normally accomplished by pulling the brush through a squeezing member located within the container neck.

An object of the present invention is to provide an adjustable applicator for use in a cosmetic liquid storage container equipped with the squeezing member, which allows the squeezing amount of the brush-containing liquid to be arbitrarily adjusted.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.As shown in each figure, the applicator of the present invention includes an applicator knob 2 integrally provided with a small diameter tube shaft 1 hanging downward; It is composed of a coating brush 3 and a squeeze amount adjusting member 4 attached to the lower end of the brush 1.

The applicator knob 2 has a large-diameter cylindrical shape, and has screw grooves 5 and 6 formed on the inner periphery of the upper and lower halves, respectively, and the diameter is reduced from the middle part of the inner surface to integrate the small-diameter long tube shaft 1. It is installed vertically. The lower end of the tube shaft 1 is open, and the outer wall surface of the lower end is cut to form a thin tube wall.

The application brush 3 has dense bristles 8 planted on the outer surface of a bottle-shaped base 7 made of an elastic material such as rubber, and a mounting portion 9 that expands upward from the constriction at the upper end is attached to the outer surface of the lower end of the tube shaft 1. It is connected and connected by fitting into it. In the figure, the mounting portion 9 is located at the inwardly bent portion 11 of the lower end of the outer skin tube 10 that is fitted and wrapped around the outer surface of the tube shaft 1.
Although an example is shown in which the holder is held and fixed, this method does not necessarily have to be used. For example, the outer surface of the mounting portion 9 may be fastened with a suitable fastening ring.

The aperture amount adjustment member 4 is connected from the back surface of the top wall of a cap-shaped adjustment knob 13 attached to the upper half of the coating knob 2 by screwing the thread 12 on the lower outer surface into the thread 5, and the pipe shaft. An adjustment rod 14 that extends freely through the inside of the brush 1 and reaches the bottom of the base 7 of the application brush 3 is suspended.
The lower end of the adjustment rod 14 is formed into a rounded portion 15.

That is, in the steady state shown by the solid line in FIG.
When the adjustment knob 13 is screwed in and lowered relative to the application knob 2, the adjustment rod 14 descends, as shown by the two-dot chain line, and the base body 7 of the application brush 3 is stretched downward, thereby reducing the outer diameter of the dense bristles 8.

As shown in FIG. 1, the applicator is attached to the outer surface of the mouth and neck part 17 in such a way as to fix the aperture member 18 made of an elastic material that is installed inside the mouth and neck part 17 of the container body 16 containing the cosmetic liquid. The application knob 2 is attached to the small diameter upper outer surface of the spout member 19 through the threaded groove 6 on the lower inner periphery of the applicator knob 2.
The aperture member 18 is dish-shaped and has a through hole in the center of the bottom wall that is smaller in diameter than the outer diameter of the dense bristles 8 through which the applicator brush 3 of the applicator is inserted. When the application brush 3 is pulled out, the peripheral edge of the through hole squeezes the brush bristles 8 having a larger diameter to reduce the amount of liquid contained in the brush 3.

As mentioned above, in the applicator of the present invention, the outer diameter of the applicator brush 3 can be adjusted, and the degree of sliding contact between the dense bristles 8 and the periphery of the through-hole of the aperture member 18 can be adjusted, so the amount of liquid contained in the applicator can be adjusted. The amount of squeezing can be adjusted, and the amount of liquid in the brush 3 can be adjusted to an amount suitable for application.

According to the present invention, the amount of liquid contained in the application brush 3 can be adjusted as desired, which is convenient. In addition, the operation for this is extremely simple as it only requires rotating the adjustment knob 13, and structurally, the base 7 on which the brush bristles 8 are implanted is made of an elastic body, and this is used as the adjustment rod 14. It is simple because it expands and contracts in the axial direction, and it has the advantage of requiring no modification to the container body.
