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, Jikko 56-
One example is the "Igoki stopper valve 7" described in No. 25610 "Liquid cosmetic container".

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 unit) 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, and for this reason, there is a gap between the rim of the container and the scrubbing tool. There are disadvantages 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 5.
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 5, but if you use a squeezing tool like the one above, Since there is a step at the base of the brush C, the liquid removed by cleaning the shaft B accumulates at the base R of the brush C (Fig. 4).
This quickly penetrates the finely aligned brush tip, making it impossible to maintain a suitable amount of liquid adhesion.Also, when you try to apply makeup with the applicator shaft upright, the remaining liquid at the step may flow down the shaft B. be.

[Purpose of invention]

This invention was developed to solve the above-mentioned conventional problems.The purpose of this invention is to not only scrape off the liquid on the shaft by simply pulling out the applicator shaft from the container, but also to automatically remove the brush. An object of the present invention is to provide a container for liquid cosmetics, especially an eyeliner container, which has an optimal amount of adhesion and can be used immediately for makeup without the need for adjustments such as rubbing the tip of the brush against the rim of the container or wiping it off. It is something to do.

[Summary of the idea]

In order to achieve the above object, the present invention has a shaft squeezing part for squeezing the shaft of the applicator shaft and a brush squeezing member for squeezing the brush (application part) with a diameter smaller than the applicator shaft in the axial direction inside the mouth of the container. Double squeezing members spaced apart are provided. Both the shaft squeezing portion and the brush squeezing portion have a truncated cone shape and are formed in the inner hole of the cylindrical main portion of the double squeezing member. The minimum diameter of the truncated conical tip of the shaft squeeze part is formed to be large enough to circularly squeeze the outer diameter of the application shaft, but the brush squeeze part is formed into a thin part from the middle of the conical shape to the tip. , vertically from the tip to the base of the thin wall (along the conical generatrix)
One slit is inserted into the hole. The minimum diameter of the tip is small enough to squeeze the outer circumference of the brush.

When the applicator shaft is pulled out from the container, the slit is widened and the thin wall portion expands in a non-circular manner as the brush passes through the brush stroke part, temporarily or partially removing the liquid attached to the shaft. Wash it off. Since the thin-walled portion is originally a part of the truncated cone, it will not be rolled up as the shaft is pulled out, but it is desirable to form one slit in order to facilitate the expansion. The very small amount of liquid remaining on the shaft is then completely squeezed out by the circular shaft scrubbing section. The brush stroke part was expanded in a distorted manner,
When the shaft has finished passing, the distortion of the thin wall portion is immediately restored elastically, forming a circular shape that is approximately the same or smaller in diameter than the brush, and squeezes the outer periphery of the brush, leaving an appropriate amount of cosmetic liquid on the brush.

[Example of idea]

Embodiments of the present invention will be described with reference to the drawings. Figures 1 and 2 show a first embodiment;
The figure is a partial vertical cross-sectional view of the whole, and FIG. 2 is an enlarged vertical cross-sectional view of the double ironing member according to the present invention.

In FIG. 1, an applicator shaft 3 is fixedly installed inside an outer cap 1 and attached to the center of an inner cap 2. As shown in FIG. The applicator shaft 3 has a length that extends into the container body (7 to be described later), and holds a brush 4, which is an applicator shaft, at its tip. Since the outer diameter of the brush 4 is thinner than the applicator shaft 3, a step is formed at the base R.

A packing body 5 having an annular thick part is fitted into the applicator shaft 3 near the base attached to the inner cap 2, and the packing body 5 extends in a tubular shape along the shaft 3, and has an elastic scraper at the tip. A protruding ring portion 6 is formed. This protruding ring part 6 is for scraping off the adhering liquid on the inner surface of the squeezing member 14, which will be described later, when the pulled out coating shaft 3 is reinserted into the container body 7.

The eyeliner liquid is stored in the container body 7. The container main body 7 has a cylindrical shape with a bottom, and a cap screw member 8 is attached to the opening edge (on the opposite side from the bottom). A male screw is engraved on the outer periphery of the portion of the cap screw member 8 that protrudes from the lip of the container body 7, and this male screw is screwed into a female thread on the inner circumference of the lip of the inner cap 2, as seen in FIG. to cover the container body with the cap.

A double squeeze member 10 according to the present invention is attached to the inner hole of the mouth screw member 8. Double ironing member 10
As shown enlarged in FIG. 2, the cylindrical main body 1
1, and its inner hole is approximately cylindrical except for the squeeze portions (14 and 16) described below. A mounting portion 12 is provided at the rear end of the outer periphery of the cylindrical main body portion 11 and protrudes radially outward. It is crimped onto the inner wall of the container body 7 as schematically shown in the figure.

A shoulder 1 is provided at the outer end of the cylindrical main body 11 or at the inner hole on the inlet side.
3 is formed, and the shoulder 13 is engaged and held within the outer end of the threaded member 8 by an overhang (see FIG. 1). Continuing from the cylindrical inner hole on the inlet side, a truncated conical shaft squeeze part 14 is formed of the same elastic material as the cylindrical main body part 11. The shaft squeezing part 14 is for squeezing off the cosmetic liquid adhering to the outer periphery of the shaft 3 when the application shaft 3 is pulled out from the container body 7, and the minimum inner diameter d at the tip 14a of the truncated cone is as shown in FIG. It is preferable to set the diameter to be smaller than the outer diameter of the coating shaft 3 shown by the chain line in FIG. Therefore, the tip 14a squeezes the outer periphery of the shaft 3 while elastically expanding radially outward, and the cross-sectional shape of the squeeze portion 14 in sliding contact with the shaft 3 is circular.

A brush squeezing portion 16 is also shaped like a truncated cone and is formed integrally with the main body portion 11 deeper into the inner hole of the cylindrical main body portion 11 than the shaft squeezing portion 14 . The brush squeezing part 16 is used to squeeze the outer periphery of the shaft 3 primarily or preliminarily, and also to squeeze the outer periphery of the brush 4, which has a narrow diameter and forms a step with the shaft 3, from the middle to the tip. is formed in the thin wall portion 17, and the minimum diameter e at the tip portion 17a of the thin wall portion 17 is formed to be smaller than the minimum inner diameter d of the shaft squeeze portion 14.
The minimum diameter e may be a diameter sufficient to squeeze the outer periphery of the brush 4 relatively strongly. From the tip 17a to the thin section 17
A single slit 18 is carved from the base of the plate. The depth of the slit 18, that is, the position of the base of the thin wall portion 17, is determined by the virtual circle 1 inscribed in the base.
9 (FIG. 2) is approximately equal to or slightly larger than the outer diameter of the shaft 3.

In FIG. 2, if the double ironing member 10 is stationary and the shaft 3 is pulled out from the right to the left in the drawing, the thin part 17 of the brush ironing part 16 swells in the opposite direction to the drawing direction. slit 18
is expanded, the thin walled portion 17 expands in a non-circular manner, and the outer periphery of the shaft 3 is rubbed around the base of the thin walled portion 17 to scrape off the adhering liquid. However, the brush stroke part 16
is much smaller than the outer diameter of the minimum diameter e-axis 3,
Since the thin part 17 is not expanded uniformly all around due to the slit 18, the cross-sectional shape of the sliding contact part of the brush stroke part 16 to the shaft 3 is not a strict perfect circle, but a slightly distorted shape. Become. For this reason, there will be some leakage on the outer periphery of the shaft, but this is only a small amount.
It is completely squeezed out by the circular sliding contact portion of the shaft squeezing portion 14 that follows.

When the shaft 3 passes the brush stroke part 16, the thin part 17 immediately elastically restores its circular shape, and the slit 1
8 is also almost closed, and the tip 17a is circular and squeezes (or squeezes) the outer periphery of the brush 4, so that a large amount of liquid contained in the brush 4 is squeezed out. When the shaft 3 finally passes through the minimum inner diameter d of the shaft squeezing part 14, the liquid squeezed by the shaft squeezing part 14 falls into the step between the base R of the shaft 3 and the brush 4, and this amount is determined as described above. Since the amount of liquid is very small and the liquid contained in the brush 4 has been reduced by being squeezed by the brush squeezing part 16 as described above, the liquid that has fallen immediately permeates toward the tip of the brush and accumulates at the step. Unlike the example shown in FIG. 4, it does not cause smudging or the like, and an appropriate amount of adhesion is left on the brush 4 as a whole.

When the caps 1 and 2 are placed over the container body 7 as shown in FIG. No expansion load is applied to 16.

Next, Figure 3 shows the second part of the double ironing member of the present invention.
FIG. 2 is an enlarged vertical cross-sectional view similar to FIG. 2 showing Example 30; This double squeezing member 30 is also held in the inner hole of the cap screw member at the mouth edge of the container body 7 in the same way as in the case of the example 10, and is attached to the inner end of the cylindrical main body 31 made of an elastic material. The portion 32 is formed to stand up in the radial direction. When inserted into the container main body 7, the upright mounting portion 32 falls down as shown by the broken line and is crimped and held on the inner wall of the container main body. Similar to the previous example, a shoulder 33 is formed on the entrance side or outer end of the cylindrical main body 31, and is adapted to be engaged and held by a threaded member. Continuing from the shoulder 33, a truncated conical shaft squeeze portion 34 is formed. This tip 34a, like the tip 14a in the previous example, has a minimum inner diameter d smaller than the shaft 3 (see Fig. 2), but differs from the tip 14a in that It is not a free end. However, since the tip 34a must be elastically flexed and expanded when the shaft 3 is pulled out, the inner hole of the main body 11 following the tip 34a must be formed on a circular curved surface in order to take the relief.
It has been gouged out as a 5. From the part where the inner hole of the main body 11 returns to a cylindrical shape, a brush stroke part 36 is formed into a truncated conical shape similar to the brush stroke part 16 of the previous example, and from the middle becomes a thin wall part 37, and from the tip part 37a. One slit 3 up to near the base of thin wall portion 37
8 is placed along the cone generating line. Tip part 37
The minimum diameter e of a is the same as in the case of FIG. In addition, the action of the brush pushing part 36 is similar to that of the brush pushing part 1 of the previous example.
6, and providing the annular recess 20 at the corresponding location of the applicator shaft 3 is also the same as in the case of FIG.

As can be seen from the above description, the brush squeezing parts 16 and 36 of the present invention primarily squeeze the outer periphery of the application shaft 3 when the application shaft 3 is pulled out, but at this time, the thin parts 17 and 37 move radially outward. Strongly inflated. Since this part is made of thin-walled elastic material, it can expand considerably; however, if there is no slit, the thin-walled part may tear after repeated use, and it may be difficult to insert the applicator shaft into the container body. This is not desirable as it may cause resistance and damage the brush tip. Therefore, in the present invention, slits 18 and 38 are formed in the thin wall part, and these slits facilitate the expansion and expansion of the thin wall part, prevent the occurrence of lacerations, and eliminate strong insertion resistance, but the number of slits is 1. A book is enough;
It is rather undesirable to insert multiple slits. This is because the thin part must elastically return to its perfect circular shape immediately after the shaft is pulled out and forcefully squeeze the outer periphery of the brush, but if two or more slits are inserted radially opposite each other, This is because the elastic return force of the thin-walled portion weakens, making it difficult to press the brush.

[Effect of idea]

According to the present invention, a liquid cosmetic applicator such as an eyeliner that consists of a stem and a smaller-diameter applicator (brushes, brushes, etc.) can be cleaned by simply pulling it out of the container body. Not only is it clean, but there is no excess liquid in the application area, so you can instantly apply makeup by drawing delicate lines. There is no need to rub the tip of the brush against the rim of the container as with conventional applicators, and there is no need to stain the container or hands, or cause the cosmetic liquid to solidify on the rim of the container. Since each of the squeeze parts is formed in a truncated conical shape that slopes at an acute angle on the opposite side to the direction in which the shaft is pulled out, the squeeze parts are folded in when the shaft is pulled out, making the squeezing action inaccurate. Nothing. The usability of this type of liquid cosmetic container can be greatly improved.
