Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a container for applying liquid cosmetics, especially an eyeliner container. This invention relates to an eyeliner container that does not contain liquid.

[Conventional technology and its problems]

Liquid cosmetics such as eyeliner and mascara have an applicator shaft attached to a cap that is attached to a container containing the cosmetic liquid, and an applicator formed by a brush, a brush, or a brush at the tip of the shaft. When applying makeup, the applicator shaft and applicator part immersed in the liquid are pulled out from the container and used. that time,
Since a large amount of cosmetic liquid adhering to the applicator shaft may stain hands and clothing, various methods have been devised to scrub it off. For example, Jitsukō 56-25610
An example of this is the ``Igoki Bung Valve 7'' described in the No. ``Liquid Cosmetic Containers.''

However, this kind of conventional scrubbing tool is used as a liquid cosmetic.
In particular, there are various difficulties when trying to use it as an applicator for liquid eyeliner. This will be explained using an eyeliner applicator as shown in FIG. A is a cap, in the center of which a coating shaft B is provided, and at the tip of the coating shaft B a brush (application part) C is attached. Since eyeliner is used to draw delicate lines on the eyelids, the tip of the brush must be thin and the diameter of the entire brush must be thinner than axis B. Even if a squeezing means such as the squeezing stopper valve 7 of the above-mentioned Utility Model Publication No. 56-25610 is applied to such an applicator, the brush C removed from the container (not shown) will not have the same effect as shown by the broken line in Fig. 4. A large amount of liquid D remains. Since it is not possible to draw delicate and delicate lines with this method, it is common to try to remove excess liquid by rubbing the brush against the rim of the container. There are drawbacks such as the removal liquid accumulating and becoming dirty, and the hardened removal liquid being pushed back when the applicator is inserted into the container and mixed with unused liquid, degrading the quality.

The ideal amount of liquid to adhere to the tip of the eyeliner applicator is as shown as E in Figure 6.
The liquid must be left on the entire surface of the brush C in a thin, almost even thickness. Even if you squeeze the tip of the brush with the rim of the container as described above, the tip of the brush may end up like the tip of E in Figure 6, but if you use a squeezing tool like the one above, Since there is a step between the base of the brush and the brush C, the liquid removed by cleaning the shaft B collects at the base R of the brush C (Fig. 4), and this liquid immediately penetrates the tip of the brush, which has been carefully arranged to be thin. Because it is stored away, it is not possible to maintain a suitable amount of liquid adhesion, and there is also the disadvantage that when the applicator shaft is set up to apply makeup, the remaining liquid on the step may flow along the shaft B.

[Purpose of invention]

This invention was made to solve the above-mentioned conventional problems.The purpose of this invention is that by simply pulling out the applicator tip from the container, not only the liquid on the tip will be scraped off, but also the brush will be automatically removed. To provide an easy-to-use liquid cosmetic container, especially an eyeliner container, which has an optimal amount of adhesion, does not require rubbing the brush tip against the rim of the container many times, and has a small number of parts. be.

[Summary of the idea]

In order to achieve the above object, the present invention provides an essentially one truncated conical member made of an elastic material in the rim of the container body, tapering towards the back of the container body, and this truncated conical member is provided in the rim of the container body. The inlet side of the shaped member is formed as a thick wall part, and the tip (back) side is formed as a thin wall part, a ring-shaped ridge is formed at the boundary between the thick wall part and the thin wall part, and the thin wall part has a 1-inch wall from the tip to the base. A slit is made in the book, so that the protruding edge inherently squeezes the outer periphery of the shaft of the application shaft.
The tip of the thin part is designed to squeeze the applicator (brush), which has a smaller diameter than the shaft part.

According to the present invention, the single truncated conical member performs a two-stage squeezing action when the applicator shaft is pulled once, so that the applicator shaft that is pulled out from the container body is also squeezed cleanly. The brush part is also soaked in an appropriate amount of liquid and can be used as is.

[Example of idea]

Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a partially longitudinal side view, and FIG. 2 is an enlarged partial sectional view of the main part of the two-stage squeezing member according to the present invention.

To summarize, the eyeliner container of the present invention, as shown in FIG. 1, consists of caps 1 and 2, an applicator shaft 3 attached to them, a container body 7 containing eyeliner liquid, and a two-tiered container provided on the inner periphery of its mouth. Shigoki member 10
It consists of

The cap consists of an outer cap 1 and an inner cap 2 fixedly installed inside the outer cap.A female thread is formed on the inner periphery of the mouth edge of the inner cap 2, and an applicator shaft 3 is attached to the center of the inner cap. The application shaft 3 is connected to the container body 7
The tip or lower end (first
A brush 4, which is an applicator, is provided at the right end in the figure.
There is a step between the base R of the brush 4 and the tip of the shaft 3. A packing body 5 is attached to the base of the applicator shaft 3 so as to surround the shaft 3, and the annular thick portion of the packing body 5 comes into contact with the mouth edge (mouth screw member 8) of the container body 7 to perform a sealing action. A packing body 5 extending from the annular thick portion along the circumference of the shaft 3 forms an elastic annular protrusion 6 at its tip. The annular protruding edge 6 is used to scrape off cosmetic liquid that may adhere to the inner surface of a squeezing member 10, which will be described later, and return it to the container body when the application shaft 3 pulled out from the container body 7 is returned to the container body 7. It is something.

A cap screw member 8 is attached to the mouth edge of the container body 7. A male thread is formed on the outer periphery of the mouth screw member 8, and is screwed into the above-mentioned female thread. A two-stage squeezing member 10 according to the present invention is attached to the inner circumference of the mouth screw member 8.

The main part of the two-stage ironing member 10 is a truncated conical member made of an elastic material, with a thick wall portion 14 and a thin wall portion 17 formed therein, and a protrusion at the boundary between the thick wall portion 14 and the thin wall portion 17. The edge 16 is used as a shaft pressing part, and the tip 18 of the thin part 17 is used as a brush pressing part.

To explain in detail with reference to FIG. 2, the two-stage squeezing member 10 consists of a cylindrical main body 11 preferably made of an elastic material, and a shoulder 13 is formed on the entrance side of the inner hole (left end in the figure). 13 is engaged and held by the annular projecting portion of the screw member 8, as shown in FIG. A mounting portion 12 is integrally formed at the rear end (right end) of the outer periphery of the cylindrical main body portion 11, and is crimped and held on the inner wall of the container body 7 by the inner end of the opening screw member 8. shoulder 13
Subsequently, a conical thick portion 14 is formed which tapers from the inner wall of the cylindrical main body portion 11 toward the back of the container body 7. As the conical shape becomes narrower, the thick part 1
A stepped portion 15 is formed in an annular shape recessed from the conical inner surface of 4, and an annular protrusion 16 is formed between this stepped portion 15 and the conical inner surface. The inner diameter of this protruding edge 16 is approximately equal to or slightly smaller than the outer diameter of the coating shaft 3, as shown by the chain line in FIG. The protruding edge 16 constitutes a shaft squeeze portion as will be explained later.

Following the stepped portion 15, a thin portion 17 is formed that tapers at approximately the same slope as the thick portion 14, and its tip 18 has an inner diameter that is approximately equal to or slightly smaller than the outer diameter of the brush 4 shown by the chain line in FIG. It is said that A slit 19 is inserted into the thin wall portion 17 along the conical generatrix from the tip 18 to the base (step portion 15). The tip 18 of the thin portion constitutes a brush stroke portion.

Two-stage squeezing member 10 having the above configuration
The operation when pulling out the applicator shaft 3 from the container body 7 equipped with the same will be explained with reference to FIGS. 3 and 4. Axis 3
When the material passes through the squeezing member in the direction of the arrow in FIG. It is in a state of being The thickness of the thin wall portion 17 is stretched and becomes thinner, and the slit 19
are expanded as shown in FIG. 4A to facilitate passage of the shaft 3. Although the thin portion 17 is illustrated as being expanded into a circular shape in FIG. 4 (cut end surface taken along the line A--A in FIG. 3), it may actually be expanded into a distorted shape that is not a perfect circle. In this way, the cosmetic liquid adhering to the shaft 3 is washed off by the tip 18 that partially slides around the shaft 3 and the protrusion 16 that slides in a perfect circle. The projecting edge 16 completely squeezes the entire outer periphery of the shaft 3, so it is called a shaft squeeze portion.

When the shaft 3 finishes passing through the thin wall portion 17 and the ridge 16, the thin wall portion 17 and the thick wall portion 14 immediately return to the shape shown in FIG. 2 due to the elasticity of their materials. . At this time, the tip 18 of the thin wall portion 17 squeezes the outer periphery of the brush 4 to squeeze out an appropriate amount of excess liquid contained therein. FIG. 4B shows the cut end surface of the thin part 17 corresponding to line A-A in FIG. 3 when the outer periphery of the brush 4 is being squeezed, and the slit 19 is closed like a single line. . The tip 18 is originally used for squeezing the brush, so it is called a brush squeezing portion.

According to the present invention, when the shaft 3 is pulled out, the outer periphery of the shaft is pressed primarily by the tip 18 of the thin walled portion, and the sliding contact portion at the end, for example, the open slit 19
Only the adhering liquid remaining in the portion (FIG. 4A) is finally completely squeezed off by the shaft squeezing portion (flange 16). Therefore, the amount of liquid that finally falls into the step R at the tip of the shaft is very small, unlike the conventional example shown in FIG. Since the amount of liquid contained is reduced by being squeezed by the squeezing part (tip 18),
A small amount of liquid that has fallen into the step R immediately permeates toward the tip of the brush, so that excess liquid does not remain locally attached. In this manner, according to the present invention, by simply pulling out the applicator shaft 3 from the container body 7, a coating area with an ideal amount of liquid deposited as shown in FIG. 6 can be obtained.

When the drawn-out applicator shaft 3 is returned to the container body 7, the brush 4 comes into contact with the squeezing member, particularly its conical portions 14 and 17, and deposits the liquid thereon, as can be imagined from FIG. This adhered liquid is subsequently scraped into the container body 7 by the incoming elastic annular ridge 6, so that both the inner surface of the thick wall portion 14 and the inner surface of the thin wall portion 17 are always kept clean. It can be done. When the shaft 3 is pulled out, the annular protrusion 6 can easily lie down in the opposite direction to the pulling direction and pass through the squeezing member due to its elasticity and shape.

[Effect of idea]

According to the present invention, an applicator for liquid cosmetics such as eyeliner, which consists of a stem and an applicator with a smaller diameter (brushes, brushes, etc.), can be simply pulled out of the container body, and the applicator can also be used as an applicator. Since the skin is squeezed at the same time and only the appropriate amount of cosmetic liquid is contained in the application area, it is possible to instantly apply makeup by drawing delicate, delicate lines. Since the two functions of squeezing the shaft and squeezing the applicator are essentially performed using two parts of one conical member,
It is economical and easy to manufacture. Thus, according to the present invention, it is possible to provide a liquid cosmetic container such as an eyeliner container with two functions using essentially a single member, thereby greatly increasing its usability.
