Description

[Detailed Description of the Invention] The present invention relates to an improvement in a container for storing cosmetic application liquids such as mascara.

In this type of container, the brush for application is always immersed in the liquid, and therefore, before use, it is necessary to squeeze the liquid contained in the brush to adjust the amount of liquid suitable for application.

It is an object of the present invention to provide a cosmetic application liquid storage container with an adjustable squeezing amount, which allows the squeezing amount of the brush-containing liquid to be adjusted as desired by an extremely simple operation.

Embodiments of the present invention will be described below with reference to the accompanying drawings. In each figure, 1 is a container housing a cosmetic application liquid such as mascara, 2 is a plate-shaped aperture member, and 3 is an operating tube for adjusting the amount of aperture. , 4 is a cap, and 5 is an applicator attached to the cap.

The container body 1 is tall and slender, and a screw thread 7 is formed on the outer surface of the upper mouth and neck part 6.

The diaphragm member 2 is a plate-shaped member made of an elastic material, and the outward flange 8 at the upper end is hung on the top of the mouth of the container body 1, and the peripheral wall 9 is fitted into the inner surface of the neck part 6 in a liquid-tight manner, so that it is attached to the mouth part of the container body. A sealing plug is attached, and a small diameter opening is provided in the center of the bottom wall 10, and the center of the bottom wall 10, where the opening is located, is always curved upward as shown in FIG. It is. In this case, if necessary, several cuts are made in the bottom wall 10 in the radial direction from the opening.

The operation tube 3 for adjusting the throttle amount is a small-diameter tube located inside the throttle member 2 via the inward flange 12 from the upper end of the operation tube 11 which is somewhat unexpanded and covers the circumference of the container body 1 from the upper end to the lower part. A cylindrical body 13 is integrally provided, the lower part of the diaphragm member 2 that reaches the bottom wall 10 is used as a foot 14, and a striation 15 is formed on the outer surface of the upper half of the operating cylindrical body 11 that projects upward.
The screw groove on the inner periphery of the upper end is screwed into the screw thread 7 for installation.

The cap 4 has an engagement groove 16 on the inner periphery of the intermediate portion.
Thread grooves to be screwed into the threads 15 are formed on the inner periphery of the lower part, and a tapered separation peripheral wall 17 extending downward so as to be continuous with the upper end of the operation cylinder 11 is provided at the lower part.

The applicator 5 has a brush 19 attached to the lower end of a shaft 18 that passes through the opening in the bottom wall 10 of the aperture member 2 and hangs down into the container body 1. The engaging protrusion 21 is engaged with the engaging groove 16 and fixed to the inner surface of the cap 4. 22 is Packing.

In the above structure, when applying the cosmetic liquid, the cap 4 is removed, the applicator 5 integrated with the cap 4 is pulled out from the container body 1, and the brush 19 containing the liquid is removed.
However, the brush 19 has a larger diameter than the opening in the bottom wall of the diaphragm member 2, and the brush 19 is squeezed by the periphery of the opening in the bottom wall 10 of the diaphragm member 2, so that the amount of liquid contained is reduced. narrowed down.

Here, by rotating the operation cylinder 11 and raising and lowering the legs 14, the degree of upward curvature displacement of the bottom wall 10 of the aperture member 2 can be adjusted, and from the maximum aperture amount position shown in FIGS. Since it can be adjusted to the minimum aperture amount position shown in FIG. 3, the amount of liquid in the brush 19 can be adjusted to an amount suitable for application.

As described above, in the present invention, an opening is provided at the center of the opening of the container body 1 through which the applicator 5 hanging down inside the container body 1 is inserted, and a bottom wall through which the center portion is curved upward is provided. The aperture member 2 made of an elastic material having a diameter of 10 is sealed, and the degree of contact with the applicator 5 is adjusted by adjusting the degree of curvature displacement of the aperture member 2, thereby adjusting the amount of aperture. The amount can be adjusted. Moreover, since the adjustment is performed by raising and lowering the foot 14 by the screw movement of the operation cylinder 11, the adjustment is continuous and fine adjustment is possible. Moreover, the operation is simple and trouble-free, since it is simply a rotational operation of the operation cylinder 11.
