Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to an application container for liquid cosmetics such as nail polish.

"Prior Art" Conventionally, there is a coating container of this type as shown in FIG. 4, for example.

First, a capped cylindrical inner stopper 3 with a valve hole 2 is attached to the upper opening of the container body 1 that stores the liquid cosmetics.
The lower part (large diameter cylinder part) of the stepped cylindrical holder 4 located above the inner stopper is fitted and fixed by caulking or the like.

A valve body 5 that opens and closes the valve hole 2 by moving vertically in the figure is housed within the inner stopper 3. The valve stem 5a of the valve body passes through the inside of the valve hole 2 and protrudes largely above the inner plug, and is placed between the tip of the valve stem and the upper surface of the inner plug so that the valve body is always moved upward, that is, in the valve closing direction. A biasing valve spring 6 is interposed.

The middle part of a rod-shaped liquid suction member 7 for applying liquid cosmetics is fitted and held in the small-diameter cylindrical part at the top of the holder so as to be able to move up and down, and the lower end surface of the member is in contact with the upper surface of the valve body. has been done.

Therefore, when the container is used, after the container body 1 is inverted, the liquid suction member 7 is pushed into the holder 4 by pressing it against human skin or the like. As a result, the valve body 5 in contact with the liquid suction member is pushed into the inner stopper 3 and the valve hole 2 is opened. As a result, the liquid cosmetic in the body of the container flows out of the body through the valve hole 2 and is absorbed by the liquid suction member, making it possible to apply the liquid cosmetic.

"Problems to be Solved by the Invention" In the conventional coating container described above, the valve stem 5a of the valve body 5 that opens and closes the valve hole 2 protrudes greatly upward from the inner stopper 3, and liquid is deposited on the upper end surface of the valve stem. Since the structure was such that the lower end surface of the suction member 7 was in contact with it, the distance from the valve hole 2 to the tip of the liquid suction member 7 became long.
When the valve is opened for the first time of use or after being stored for a long time, it takes time for liquid cosmetics to penetrate to the tip of the liquid suction member, resulting in a lack of quick response.

In addition, the above-mentioned container has a structure in which the inner stopper 3, holder 4, etc. are individually set in the upper end opening of the container body 1, and then fixed by caulking or the like as appropriate, which makes assembly work complicated. This was one of the causes of soaring production costs.

The present invention was devised in consideration of these circumstances, and aims to provide a liquid cosmetic application container that is easy to assemble, can be manufactured at low cost, and is highly responsive and convenient.

"Means for Solving the Problems" In order to achieve the above object, the liquid cosmetic application container according to the present invention includes a container body 10 with a neck part 16 erected, and a top with a valve hole 17 on the inner surface of the mouth neck part. wall 1
8. An inner stopper 11 into which the lower part of the peripheral wall 19 hanging from the periphery is fitted, and a valve spring 1 housed in the inner stopper.
3, the valve body 12 is housed in the inner plug while being biased in the valve closing direction so as to be able to freely move up and down to open and close the valve hole, and the inner valve body 12 protrudes from the outer surface of the mouth and neck and above the mouth and neck. A cylindrical holder 14 has a lower part of the cylindrical wall 20 fitted onto the outer surface of the upper part of the circumferential wall of the plug, and the upper part of the cylindrical wall stands up above the inner plug; It is characterized by comprising a rod-shaped liquid suction member 15 that is brought into contact with or in close proximity to the upper surface of the valve body.

"Function" When using the container, for example, after inverting the container body 10 from the state shown in FIG.
When the tip of 5 is pressed against human skin A, etc., the liquid suction member 15 and the valve body 12 are moved to the holder 14 against the urging force of the valve spring 13, as shown in FIG.
and move upward relative to the inner stopper 11 to open the valve hole 17.

As a result, the liquid cosmetics in the container body 10 are transferred to the valve hole 1.
7 and is absorbed by the liquid suction member 15,
Application of the liquid cosmetic becomes possible.

At this time, the valve body 12 and the valve spring 13 are housed in the inner stopper 11, and the valve body 12 and the liquid suction member 1
5 are designed to abut as close to the valve hole 17 as possible, so that when the valve is opened, most of the liquid cosmetics that flow out immediately or directly come into contact with the base end of the liquid suction member. Liquid cosmetics quickly penetrate to the tip of the member.

After application, if the container body 10 is lifted to make the liquid suction member 15 free, the valve body etc. will move downward with respect to the inner stopper etc. by the biasing force of the valve spring 13, and the valve hole 17 will be closed. is self-evident.

``Example'' An example of the present invention will be described below based on the accompanying drawings.

In FIGS. 1 and 2, 10 is a container body, 1
Reference numeral 1 designates an inner stopper in the shape of a capped cylinder, 12 a valve body, 14 a stepped cylindrical holder, and 15 a rod-shaped liquid suction member made of felt.

The container body 10 has a neck part 15 erected at the upper end of a body part 21. A plurality of steel balls (not shown) for preventing the cosmetic from clumping together with the liquid cosmetic are housed in the body.

The inner plug 11 has a valve hole 17 on the inner surface of the mouth and neck part 16.
The lower part of the peripheral wall 19 hanging down from the peripheral edge of the attached top wall 18 is fitted. A plurality of support pieces 23 with protrusions for receiving springs are vertically disposed from the lower end surface of the peripheral wall 19 in the circumferential direction.

The valve body 12 is formed approximately in the shape of a poppet valve, and has its upper end slightly passed through the valve hole and protrudes upward in the shape of a rod, so that the valve body 12 can be freely moved up and down to open and close the valve hole 17 inside the inner plug 11. It will be stored. The valve body is always urged upward, that is, in the valve closing direction, by a valve spring 13 interposed between the valve head portion and the support piece 23 of the inner stopper.

The holder 14 has a cylindrical wall 20 with a large diameter portion 20a.
are formed in the intermediate diameter portion 20b and the small diameter portion 20c,
The inner surface of the large diameter portion of the inner plug is appropriately formed into a stepped surface, and is connected to the outer surface of the mouth and neck and the upper outer surface of the inner stopper peripheral wall that projects above the mouth and neck through engagement means 24a and 24b of uneven stripes, respectively. It gets stuck. The intermediate diameter portion and the small diameter portion are made to stand up above the inner stopper. A cylindrical auxiliary liquid suction member 25 made of urethane is fitted into the intermediate diameter portion 20b.

The rod-shaped liquid suction member 15 has an intermediate portion inserted into the small diameter portion 20c of the holder so as to be vertically movable, and its lower end surface is brought into contact with or close to the upper end surface of the valve body 12.

In the figure, 26 is a cap, and 27 is an auxiliary cap fitted inside the cap to prevent drying. In addition, each part is molded and manufactured using synthetic resin material as appropriate.

Therefore, in this embodiment, as shown in FIG.
