Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a container for liquid cosmetics such as mascara and eyeliner. In particular, the present invention relates to a liquid cosmetic container which is provided with a rod-shaped applicator such as a brush with a shaft so that the rod-shaped applicator can be freely removed, and the rod-shaped applicator can be easily replaced. Furthermore, the present invention relates to a cartridge type liquid cosmetic container in which the bottle of the container is also replaceable.

[0002]

2. Description of the Related Art A liquid cosmetic container such as mascara is provided with a container body for containing the liquid cosmetic, a rod-shaped applicator which can be taken in and out of the container body, and a cap for closing the mouth of the container.
Here, the rod-shaped applicator is usually connected under the cap, and when the cap is removed, it comes under the cap and comes out of the container. Also, some have an ironing member having a narrow ironing opening for ironing out excess liquid cosmetics,
When the rod-shaped applicator is removed from the container, an appropriate amount of liquid cosmetic is attached to the brush at the tip of the rod-shaped applicator.

[0003] Since liquid cosmetics such as mascara and eyeliner must be dried quickly after applying to eyelashes and eyes (DRY UP characteristic), the liquid component of the liquid cosmetic consists of a highly volatile solvent. Therefore, when the liquid cosmetics attached to the brush come into contact with the air outside the container, they harden and tend to stick. Furthermore, the concentration of the liquid cosmetic in the container gradually increases, and the liquid cosmetic tends to become a viscous liquid. For this reason, when the brush becomes rough and is squeezed by the ironing member, the bristle of the brush is easily broken or broken. If you leave it as it is, you will not be able to make beautiful makeup on eyelashes, eyes, etc.
There is a request to replace a rod-shaped applicator such as a brush.
In addition, when the brush bristles come into contact with air, germs may proliferate during long-term use.

In addition, depending on the person, the shape of eyes and eyelashes, shading,
Because of the different lengths, there are various shapes and sizes of brushes and brushes, and there is also a demand to freely select and attach a brush and a brush that suits the user from such various brushes and the like.

[0005] A liquid cosmetic container having a replaceable rod-shaped applicator has been proposed in Japanese Utility Model Publication No. 60-38413. However, the container specifically described in the same issue is envisioned based on the basic idea of finishing the exterior product beautifully and exchanging only the internal member, and therefore has a complicated mechanism and a large number of members. Further, the cartridge type liquid cosmetic container described as an example in the same issue requires an unnatural intermediate cylinder, and is not at all likely to be put to practical use. After all, until now, liquid cosmetic containers capable of replacing a rod-shaped applicator and a liquid cosmetic bottle have not been put to practical use.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and is directed to a container for liquid cosmetics such as a mascara or an eyeliner. It is an object of the present invention to provide a liquid cosmetic container that can be easily replaced.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a sectional view showing the structure of a liquid cosmetic container according to one embodiment of the present invention. FIG. 2 is a diagram showing details of a cap of the liquid cosmetic container of FIG. The liquid cosmetic container 1 of this embodiment includes a cap 3, a rod-shaped applicator including a brush shaft 5 and a brush 10, an ironing member 7 (also used as packing), and a container body 9.

The cap 3 is assembled so as to be separable from the brush shaft 5 and is screwed into the mouth 65 of the container body 9.
A female screw 23 is provided on the inner surface 21 of the lower thin portion 19 of the cap 3.
The female screw 23 is screwed with the male screw 63 on the outer surface of the container body opening 65. An inner step 17 is formed between the lower thin part 19 and the upper thick part 13, and the upper surface of the flange 43 of the brush shaft 5 abuts on the inner step 17. A cap hole 11 penetrating vertically is formed in the center of the upper thick portion 13 of the cap 3. The upper part of the cap hole 11 is tapered downward and has a funnel shape.
A locking step 14 is formed in the middle of the hole. As shown in FIG.
5b protrudes inward. The detent rib 15b is
The inner hole is provided with eight circumferentially distributed portions, and between each rib is a detent groove 15a cut in the radial direction. A locking projection 37 of the brush shaft 5 described below contacts the upper surface of the locking step portion 14. The detent groove 15a has a coaxial 5
Of the anti-rotation rib 39 enters.

The brush shaft 5 is assembled detachably from the cap 3 as described above, and the middle portion 45 and the lower portion 47 of the brush shaft 5 hang right below the cap 3. Normally, the cap 3 and the brush shaft 5 are integrated, and when the cap 3 is removed, the brush shaft 5 and the brush 10 at the tip thereof come out. When the brush shaft 5 is housed in the container body 9, the middle part 45 of the coaxial 5 is located in the mouth 65 of the container body 9, and the lower part 47 is located in the container body 9. The middle section 45 has a cylindrical shape with a taper slightly lower. The lower part 47 has a round cylindrical shape. At the lower end 49 of the lower portion 47, a core shaft 81 of the brush 10 is implanted.
A large number of brush hairs 83 grow around the core shaft 81.

On the middle part 45 of the brush shaft 5, a coaxial
A disk-shaped flange portion 43 is formed to protrude largely on the outer periphery of the disk. In the assembled state, the flange 4
The upper surface of 3 is in contact with the inner step 17 of the cap 3 and the lower surface is in contact with the flange portion (packing portion) 51 of the ironing member 7.

A top 33 projects from the flange 43 of the brush shaft 5, and its upper end 31 projects above the upper surface of the cap 3 through the cap hole 11. On the outer surface of the lower portion of the top portion 33 (immediately above the flange portion 43), detent ribs 39 and 41 are formed so as to protrude vertically. The detent ribs 39 and 41 are provided at four locations in a circumferential distribution, and are engaged with the detent grooves 15a of the cap 3 by entering the detent grooves 15a. The engagement between the detent ribs 39 and 41 and the detent groove 15a prevents the brush shaft 5 and the cap 3 from being detented, so that inadvertent rotation of the two prevents inconvenience to the user. In addition, since the detent rib 41 is located below the opening surface of the slit 35, the length is shorter than the rib 39.

On the outer surface of the middle portion of the top portion 33 of the brush shaft 5,
Locking projections 37 that protrude round outward are provided at two locations on the left and right. The locking projections 37 and 37 ′ protrude above the locking step 14 in the cap hole 11 so that the brush shaft 5 does not fall down from the cap 3. That is,
As described above, since the flange 43 is in contact with the inner step 17 of the cap, the detent rib 15b
Are the locking projections 37, 37 'of the brush shaft 5 and the flange portion 4.
3, the cap 3 and the brush shaft 5 are assembled.

A slit 35 is formed between the left and right locking projections 37 and 37 '. The slit 35 is at the top 3
This is an oval-shaped hole that extends slightly up and down, stealing the meat of the core of No. 3. Due to the presence of the slit 35, the left and right locking projections 3
When a certain amount or more of inward force is applied to 7, 37 ', the outer flesh portion of the slit 35 bends inward and the left and right locking projections 37, 37' are retracted inward. When the top end 31 of the brush shaft 5 is pushed down by such an operation, the locking projections 37 and 37 ′ are retracted inside and enter the inside of the locking step 14 of the cap hole 11.
When the top end 31 is further pushed down, the locking projections 37, 3
7 'is pulled down inside the detent rib 15b below the locking step 14, and the brush shaft 5 is separated from the cap 3 below. The slit 35 has an operation to facilitate such a separating and assembling operation. Further, the method of engaging the brush shaft 5 with the cap 3 is not limited to this, and may be an ordinary concave-convex engagement method, and any engagement method may be used as long as the top portion 33 is pressed downward. .

The ironing member 7 is a hollow cylindrical member as a whole, and is made of an elastic member such as rubber. Ironing member 7
As described above, the upper end of the flange 5
It is 1. The flange portion 51 rests on the mouth upper end 61 of the container body 9. When the cap portion 3 is attached to the container body 9, the flange portion 51 is pressed against the cap 3 from above via the brush shaft flange portion 43,
Appropriately pressed to act as packing. Thereby, the liquid cosmetics and the volatile gas in the container body 9 do not leak out of the container body.

The middle portion 53 of the ironing member 7 hangs down along the inner surface of the container body opening 65. An outer collar 55 is provided on the outer periphery of the lower end of the ironing member 7 so as to protrude outward in a ring shape. The same portion 55 includes a container body opening 65
To be hooked on the lower end surface of the As a result, the upper and lower ends of the mouth 65 are sandwiched between the flange 51 at the upper end of the ironing member 7 and the outer collar 55 at the lower end, and the ironing member 7 is fixed to the container body opening 65. Since the ironing member 7 is made of an elastic member such as rubber, when the ironing member 7 is deformed by the outer collar 55 and pushed into the mouth 65 at the time of assembly, the outer collar 55 becomes
After entering the container body 9, it spreads out by its own elasticity.

Inside the lower end of the squeezing member 7, a funnel-shaped squeezing portion 57 having a downward taper is formed. An ironing opening 59 which is a circular opening is formed in the center of the ironing portion 57. The ironing opening 59 comes into contact with the brush 10 or the outer surface of the brush shaft 5 when the cap 3 and the brush shaft 5 are removed, and plays a role of scraping off the liquid cosmetics adhering thereto. By appropriately selecting the diameter of the ironing opening 59 and the elasticity of the ironing part 57, it is possible to cause a suitable amount of the liquid cosmetic to adhere to the brush 10. In addition, the ironing member 7 is not limited to an elastic body such as rubber, but may be formed as a bottle having a structure in which polypropylene is laminated as long as the brush shaft 5 can be properly ironed.

The container body 9 is a bottomed cylindrical bottle. The upper end portion of the container body 9 is a one-stage small-diameter mouth portion 65. A male screw 63 is cut on the outer surface of the opening 65, and the female screw 23 of the cap 3 is screwed. The ironing member 7 described above fits into the inner surface of the mouth portion 65. The portion other than the mouth of the container body 9 is a cylindrical bottle portion 69 and a bottom 71 thereof.

The overall operation of the container of the embodiment shown in FIGS. 1 and 2 will be described. First, at the time of assembly, the ironing member 7 can be incorporated by pushing it into the container body opening 65 as described above. When assembling the brush shaft 5 and the cap 3, the brush shaft 5 is inserted into the container body 9, the cap 3 is covered from above, and the cap is screwed into the container body opening 65. The top 33 of 5 gradually rises in the cap hole 11, and finally the locking projection 37 rides on the locking step 14 as shown in FIG. 1, and the brush shaft 5 is assembled with the cap 3. At this time, as described above, due to the presence of the slit 35, the locking projections 37 and 37 'smoothly move inward. Further, since the detent grooves 15a are formed at eight locations on the circumference, they naturally match the detent ribs 37 of the brush shaft.

Next, when replacing the rod-shaped applicator, the upper end 31 of the brush shaft top 33 is pressed by a finger with the cap 3 and the brush shaft 5 removed from the container body 9. Then slit 3
By the operation of 5, the left and right locking projections 37 and 37 'are shifted inward, and the locking projections are disengaged from the locking step 14 of the cap. By further pressing the cap downward, the locking projection 37 comes off below the inner step 17 of the cap, and the cap 3 and the brush shaft 5 are separated. The reason why the inner hole 11 has a funnel shape is to make it easy to insert a finger.
At this time, the user can discard the brush shaft 5 without touching the brush shaft 5 at all. The installation of the new rod-shaped applicator is the same as that at the time of the above-mentioned assembly.

FIG. 3 is a view showing a variation of the applicator. FIG. 3A shows a brush in which brush hairs 83 grow on a straight core shaft 81A. In FIG. 3B, the core shaft 81B is curved so that mascara can be easily attached to the eyelashes. FIG. 3C is an example in which brush hair is not used. The user can freely select these brush axes.

The cap 103 is assembled so as to be separable from the brush shaft 105, and is screwed into the mouth of the container body 109. The screwing portion between the cap 103 and the container body 109 and the engaging portion between the brush shaft 105 and the cap 103 have the same configuration as the embodiment of FIG. A cap hole 111, which is a cylindrical hole, is formed in the center of the upper portion of the cap 103.
Two grooves 112 having a certain width are formed diagonally on most of the inner surface in the middle of the hole. A slightly thick flange is formed below the hole, and a detent groove 115 is formed on the inner surface of the flange.

The inner cap 102 comprises a top portion 91 and a hollow cylindrical hanging tube 98 opened downward. Hanging cylinder 9
The outer diameter of 8 is substantially equal to the inner diameter of the cap hole 111 of the cap 103. The hanging cylinder 98 has U-shaped slits 97 cut at two diagonal positions on the outer surface, and a retaining bend piece 95 extending downward from the top 91 is formed. The width of the retaining bend piece 95 is substantially the same as the width of the groove 112 provided in the cap hole 111 of the cap 103 described above. An outwardly projecting portion 96 is formed on an outer surface of the retaining bend piece 95, and the projecting portion 96 is fitted in a groove 112 of the cap 103. Abuts the top surface of the When the inner cap 102 is inserted into the cap 203, the bend pieces 95 bend inward.

The protruding portion 96 provided on the hanging cylinder 98 of the inner cap 102 is provided with the groove 1 provided in the cap hole 111.
When the upper end of the protrusion 96 abuts the upper end of the groove 112, the upward movement is stopped.

When the brush shaft 105 and the cap 103 are assembled, the top surface of the brush shaft 105 is
02 contacts the lower surface of the top 91. When the top 91 of the inner cap 102 is pushed downward in the cap hole 111 of the cap 103, the brush shaft 105 is pushed down, and the locking projection 137 is pressed inward by the locking step 114. At this time, the locking projection 137 is operated by the action of the slit 135.
Is shifted toward the inside, and the locking protrusion is the locking step 1 of the cap 103.
It falls off from 14. By these actions, the cap 1
03 and the brush shaft 105 are separated, and the rod-shaped applicator is replaced.

By providing the inner cap 102 on the cap 103, the reliability of the vertical movement of the brush shaft 105 in the axial direction is increased, and the brush shaft and the cap can be more easily separated. When the inner cap 102 is dropped downward, the brush shaft 105 is not loaded, and this is only when the brush shaft is replaced. The inner cap also makes the appearance of the container more favorable.
