Description

[Detailed Description of the Invention] "Industrial Application Field" This invention relates to an application container that is used as a cosmetic tool by containing liquid cosmetics such as liquid lipstick and nail polish.

``Prior Art'' Conventionally, as this type of applicator container, one is known in which an applicator such as a brush is installed at the opening of the container body via a valve mechanism (for example,
12351 Publication, Utility Model Publication No. 61-12134, etc.). This conventional applicator container is configured so that the valve opens by pressing the tip of the applicator, and the liquid cosmetic in the container body is sent to the applicator.

"Problems to be Solved by the Invention" By the way, in the conventional applicator container mentioned above, if the applicator body is soft, the pressing force applied to the tip of the applicator body will not be transmitted to the valve mechanism. However, there was a drawback that liquid cosmetics could not be supplied to the application body, and when a hard application body was used, the application body was damaged by the pressing force.

This idea was made in view of the above circumstances, and even when a soft applicator is used, liquid cosmetics can be supplied to the applicator, and even when a hard applicator is used, liquid cosmetics can be supplied to the applicator. The purpose is to provide a coating container that does not damage the skin.

``Means for solving the problem'' This idea consists of a flexible tube container for containing liquid cosmetics, and a cosmetic discharge port attached to the mouth of the tube container. a holder, an applicator provided at a discharge port of the holder, a valve mechanism for opening and closing the discharge port of the holder, and a valve rod movably provided within the tube container for operating a valve body of the valve mechanism; An operation plate provided at the tip of the valve stem and having a larger diameter than the valve stem, and an outer cylinder that covers the outer periphery of the tube container, and a peripheral wall of the outer cylinder at a position facing the operation plate. The push operation part is provided with a notch formed around the periphery, leaving one or more bent parts.

"Function" When the applicator is directed downward and the press operation part on the outer cylinder circumferential wall is pressed inward, the operation plate is operated via the outer wall of the tube container, and the valve stem is moved. When the valve body moves in accordance with the movement of the valve stem, the valve mechanism opens, and the cosmetic in the tube container flows out to the applicator through the discharge port.

When the pressure on the pressing operation part is stopped, the valve stem and the like return to their original positions, the valve mechanism closes the discharge port, and the flow of liquid cosmetic to the applicator is stopped.

In the illustrated example, the applicator 3 is made of a brush made of bundled fine bristles, and its base end is fixed to the discharge port 2c of the shaft portion 2d.

Note that, inside the holder 2, an occlusion body 11 that absorbs liquid cosmetics is attached. This occlusion body 11 has good absorbency for liquids such as liquid cosmetics,
It is formed into a cylindrical shape from a highly elastic foam such as sponge. This storage body 11 is inserted into a fitting cylinder portion 2f formed on the inner periphery of the tip of the holder 2, and its lower end is in contact with the upper surface of a valve body 13, which will be described later.

Next, the valve mechanism 4 will be explained. This includes a valve seat body 12 that is fitted into the inner peripheral surface of the mouth of the tube container 1 and partitions the inside of the tube container 1 into upper and lower parts, and a communication hole 12a of the valve seat body 12. The main components include a valve body 13 that opens and closes, and a coil spring 14 that biases the valve body 13 toward the communication hole 12a.

The valve seat body 12 has a communication hole 12a at the bottom.
A valve seat is formed at the upper end periphery of the communication hole 12a, and the upper end outer peripheral surface of the valve seat body 12 is in contact with the upper end of the mouth of the tube container 1. A flange portion 12b is formed.

In addition, a through hole 6a is formed in the bottom plate portion of the operation plate 6 so that the flow of the cosmetic inside the tube container is not obstructed by the operation plate 6.

Next, the function and method of use of the coating container having the above structure will be explained.

First, when discharging liquid cosmetics, the applicator 3 is directed downward. In this state, the valve seat body 1 is moved by the valve body 13 pressed by the coil spring 14.
Since the communication holes 12a of No. 2 are closed, there is no fear that the liquid cosmetic will be discharged from the tube container 1 to the applicator 3.

Next, as shown in FIG. The valve body 13 is pushed down against the force, and the communication hole 12a of the valve seat body 12 is opened. Then, the liquid cosmetic in the tube container 1 flows into the holder 2 through the communication hole 12a, and at the same time, the occlusion body 11 is compressed by the valve body 13, and the liquid cosmetic that has been absorbed until now flows into the discharge port. It flows out to the application body 3 through 2c.

When the pressing operation of the pressing operation part 9 is released, the valve stem 5,
The valve body 13 and the like return to their original positions, and the valve body 13 contacts the valve seat and closes the communication hole 12a again, so that excess liquid cosmetic does not fall.

According to the application container configured as described above, since the discharge port 2c is normally closed reliably by the valve mechanism 4, the liquid cosmetic will flow out into the application body 3 unless the pressing operation part 9 is pressed. Never. Therefore, even if the applicator is vibrated while being carried around, there is no need to worry about inadvertently discharging the liquid cosmetic. Moreover, since there is no need to apply pressing force to the applicator 3, a soft brush or the like can be used as the applicator 3, and even if a hard applicator 3 is used, the pressing force may damage the applicator 3. There is an advantage that it never happens.

Further, according to the application container of the embodiment, since the tube container 1 containing the liquid cosmetic is housed in the outer cylinder 7 (in the illustrated example, the large diameter part 2a of the holder 2 and the bottom cylinder 10), the tube container There is no risk that 1 will be pressed inadvertently, and it is convenient to carry. Furthermore, when applying makeup, one-touch operation is possible with one hand, which has the advantage of freeing up the other hand.

When replacing the tube container 1, the bottom cylinder 10 is removed from the holder 2, and the tube container 1 and holder 2 are held and rotated relative to each other to remove the holder 2 from the mouth of the tube container 1. Next, when the replacement tube container 1 is screwed onto the holder 2 and the bottom cylinder 10 is assembled, the assembled state as shown in FIG. 1 is obtained.

This replacement operation can be carried out by attaching and detaching the holder 2 and the bottom cylinder 10 and screwing the holder 2 and the tube container 1 together, and does not require any special skills to replace the tube container 1, so it is easy. Able to carry out replacement work.
