Description

[Detailed description of the invention] Industrial application field This invention is applicable to containers for storing cosmetic liquids such as mascara, and more specifically, to scrubbing away excess liquid adhering to applicator sticks and applicator brushes. The present invention relates to a cosmetic liquid storage container with a body.

Prior Art FIG. 1 shows an example of the structure of a conventional cosmetic liquid storage container of this type. A hollow cylindrical outer cylinder 2 is screwed to the outside of a hollow cylindrical container body 1 containing a cosmetic application liquid A, and a hollow cylindrical squeezing body 3 made of a soft material is attached to the upper end thereof. is attached so as to be locked to this outer cylinder 2. Then, the lower end portion of this squeezing body 3 is locked to the container body 1.

Further, this ironing body 3 has an ironing part (ironing hole) 3a formed inwardly at approximately the middle in the axial direction, and a coating rod 5 is provided on the lid body 4 that is placed over the outer cylinder 2.
are provided integrally. The applicator rod 5 passes between the squeezing portions 3a and extends into the container body 1, and is provided with an applicator brush 6 at its tip.

On the other hand, when the container main body 1 is lowered in the drawing, the inner diameter of the squeezed portion 3a increases as the squeezed portion 3a is extended radially outward, and conversely, when raised, the inner diameter of the squeezed portion 3a becomes smaller. Therefore, in this conventional container, the inner diameter of the squeezing portion 3a can be adjusted by raising or lowering the container body 1, and the amount of cosmetic liquid that adheres to the applicator brush 6 at the tip of the applicator rod 5 can be adjusted. It is.

In this prior art, since the container body 1 is screwed to the outer cylinder 2, the position at which the degree of squeezing of the squeezing portion 3a is set is determined by the relative rotation between the container body 1 and the outer lid 2. It will not move unless you give it.

By the way, in a container with such a conventional structure, if the squeezing force of the squeezing portion 3a is set (strongly) to the extent that the squeezing portion 3a comes into pressure contact with the applicator rod 5, the squeezing force may remain in that setting state. After pulling out the applicator stick 5, it is difficult to insert it when you try to put it away, and moreover, when inserting the applicator stick 5, the applicator stick 5 and applicator brush 6 are squeezed in the opposite direction, resulting in the cosmetic liquid being squeezed out. This causes an inconvenience in that the liquid flows out of the container.

On the other hand, if the squeezing force of the squeezing part 3a is set to be weak, for example, as shown in FIG. The problem arises that the liquid comes out as it is.

Here, if these settings are changed when putting in and taking out the applicator stick 5, the above-mentioned inconvenience can be solved, but conversely, when using the container body 1 each time,
There is an inconvenience in using the device as you have to turn the button to change the settings each time you use it, and you end up wasting extra time when applying makeup.

Purpose of the invention This invention was developed in view of these circumstances.The adjustment state of the squeezing part can be easily returned to its original state, and the diameter of the squeezing part can be reduced only when the applicator stick is pulled out, thereby eliminating unnecessary waste. To provide a novel cosmetic liquid storage container which allows the cosmetic liquid to be squeezed out and the straining part to be easily adjusted with one hand.

Structure of the device In this device, an inner container for storing cosmetics is provided inside a cylindrical container main body so as to be slidable in the axial direction, and a straining body having a straining hole is attached to the upper end of the inner container. The ironing body is elastically deformed by pushing from the bottom plate part, and the diameter of the ironing hole is reduced.

Embodiment Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. 2 to 4.

In the figure, reference numeral 10 is a container body for accommodating an inner container 11 for storing a coating solution, and 12 is a coating brush 1 that can be inserted into and taken out from the inner container 11.
This is a lid body having an applicator rod 14 with 3 attachments.

The container body 10 is formed in a cylindrical shape with a bottom, for example, from metal or synthetic resin, and
This bottom plate portion 10a has an opening 15 that communicates with the inside and outside.
is formed. A cylindrical connecting stopper 16 having a male thread 16a on its outer circumferential surface which is screwed into the female thread 12a of the lid 12 is fitted into the rim of the container body 10.

Moreover, the middle container 11 accommodated inside the container body 10 is slidably provided along the axial direction of the container body 10, and has an outer diameter slightly smaller than the inner diameter of the container body 10 as a whole. It is formed into a cylindrical shape with a bottom. And, the bottom plate part 11a of this inner container 11
is formed into a cylindrical portion having a slightly smaller diameter than the opening 15 of the container body 10 via the stepped portion 17, and protrudes from the opening 15. On the other hand, like the bottom plate part 11a, the upper end of the medium container 11 is formed into a small-diameter cylindrical part via a step part 18, and the applicator rod 1 is attached to the outer periphery of this part.
An ironing body 19 having an ironing hole (ironing part) 19a through which the iron 4 passes is fitted. The ironing body 19 is entirely made of a material with appropriate elasticity such as rubber, and when the application rod 14 is pulled out, the ironing hole 19a allows the application rod 14, the application brush 1
3. It is designed to squeeze off excess coating liquid that adheres to the coating.

Further, to add an explanation to the connecting stopper 16 fitted to the mouth edge of the container body 10, this has a flange portion 20 on the outer circumferential surface of the central portion, and the lower surface of the flange portion 20 is connected to the container body 10. It is inserted until it touches the edge of the mouth. Of the inner circumferential surface of this connecting stopper 16 facing the outer circumferential surface of the squeezing body 19, at least a sliding limit position (the fourth
The inner circumferential surface of the portion corresponding to the range up to the position shown in the figure is tapered so that the inner diameter gradually becomes smaller than the outer diameter of the ironing body 19 as it goes toward the sliding limit position side (the lid body 12 side). It is formed on the surface 16b.

Now, to supplement the explanation about the applicator rod 14 with the applicator brush 13, this applicator rod 14 is as follows:
It is formed integrally with the top plate portion 12b of the lid body 12, and the applicator brush 13 at the tip thereof is provided so as to be tapered.

In the figure, the reference numeral 25 is a coil spring (elastic member) that biases the inner container 11 toward the bottom plate portion 10a of the container body 10. It is provided between the connecting plug body 16 and the connecting plug body 16 .

Next, the operation of the cosmetic liquid storage container configured as described above will be explained.

As shown in FIG. 3, when the lid 12 is closed and the inner container 11 is not pressed upward (lid 12), the squeezing body 19 is kept in its original shape.
There is no change in the inner diameter of the straining hole 19a. At this point, open the lid and hold the container body 10 with one hand, for example.
When the bottom plate portion 11a of the medium container 11 is pushed using a desk or the like, the squeezing body 19 at the upper end of the medium container 11 slides upward. Then, when this squeezing body 19 slides upward, the squeezing body 19 will, in the sliding process,
Under the action of the tapered surface 16b, it is gradually elastically deformed inward, and at the sliding limit position of the ironing body 19, the fourth
Transform as shown. Therefore, the inner diameter of the straining hole 19a also becomes smaller. In addition, the medium container 1
When the pressure of 1 is released, the squeezing body 19 moves to the coil spring 2.
5, it descends together with the inner container 11 and returns to its normal position, restoring its original shape.

As can be understood from the above operation, the applicator rod 14
When removing the lotion, press the inner container 11 to reduce the diameter of the squeezing hole 19a to squeeze out excess lotion. Also, when inserting the applicator stick 14, release the pressure on the inner container 11 and squeeze out the excess lotion. Hole 1
The diameter of 9a is increased, so that the applicator stick 14 can be easily inserted, and the cosmetic liquid will not flow out of the container without being squeezed in the opposite direction. Moreover, it is convenient to easily change the inner diameter of the straining hole 19a with one hand, and since the straining body 19 always returns to its normal position by the action of the coil spring 25, during use, Each time, squeeze hole 19a
There is no need to change the inner diameter setting.

Note that even if the applicator brush 13 is tapered as in the embodiment, the ironing hole 19a of the ironing body 19 can be made smaller by the action of the tapered surface 16b, so that the excess application liquid attached to the applicator brush 13 can be reduced. You can also squeeze it out reliably.

A protrusion 30 is provided in a protruding manner. The second embodiment having such a structure also has the same effects as the first embodiment described above, and the annular protrusion 30 acts as a seal to prevent the coating liquid from flowing. Further enhances leakage prevention,
Good sealing performance can be achieved.

Next, a third embodiment of the present invention will be described with reference to FIGS. 8 and 9. In this embodiment, the structure of the squeezing body attached to the upper end of the inner container 11 is changed, and this squeezing body 35 is made of an elastic material such as rubber and has a narrow middle part and is elastic and constricted inward in the radial direction. It is formed into a cylindrical shape, and the constricted part, ie, the squeezing part 35a, is the coating rod 14 and the coating brush 1.
3. It is designed to squeeze off excess coating liquid that adheres to the coating. The upper end of the squeezing body 35 is fitted into the outer circumference of the lower end of the connecting stopper 36 for screwing the lid, and the lower end is fitted into the upper end of the medium container 11.

This embodiment also has almost the same effects as the first embodiment, but the squeezing body 35 is connected to the inner container 11 and the connecting stopper 3.
6, it is possible to reliably prevent leakage of the coating liquid.

Further, a fourth embodiment of the present invention will be described with reference to FIGS. 10 and 11. In this embodiment, as in the previous third embodiment, the squeezing body 40 is a cylindrical expandable body with a constricted middle part, and the constricted part is the coating brush 13 and the squeezing part 40a of the coating rod 14. It is said that In addition, the above-mentioned squeezing body 4
The upper end of the connecting stopper 36' is attached to cover the upper end of the connecting stopper 36', and the lower end is fitted into the upper end of the inner container 41 for storing the coating liquid. This embodiment also has the same effects as the third embodiment.

Effects of the invention As explained above, according to this invention, when the applicator stick is squeezed, the adjustment state of the squeezing part of the body can be easily returned to the original state, so when pulling out the applicator stick, the diameter of the squeezing part is made small and the excess is removed. It has the excellent effect of being able to squeeze out the application liquid, and when inserting it, the diameter of the squeezing part can be increased to weaken the squeezing force, and such adjustments can be easily made with one hand. .
