CONSTITUTION: A liquid applicator 1 is constituted so that eau de Cologne being a liquid housed in the applicator is pushed toward a coating part 3 by a push-out mechanism. The coating part 3 is constituted from a cylindrical coating part main body 10 provided with a liquid passage 9 allowing a leading end emitting orifice 7 and a base end introducing port 8 to communicate with each other, the spherical coating ball 11 supported on the inner surface of the emitting orifice 7 in a freely rotatable manner, a ball valve 12 being the valve member for opening and closing the introducing port 8 and an elastic spring 13 arranged in the liquid passage 9 so as to close the emitting orifice 7 and the introducing port 8 from the inside by elastic energizing force. By this constitution, since the emitting orifice 7 is closed by the coating ball 11 and the introducing port 8 is closed by the ball valve 12 in the coating part 3, the eau de Cologne in the applicator 1 is held to a highly airtight state and hard to evaporate and diffuse.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid applicator which is configured to push out easily evaporating liquids such as perfume such as cologne liquid and liquid medicine for soothing from an inside of the main body toward an application portion by an appropriate extrusion mechanism. The present invention relates to an application section, and more particularly, to a device devised so that the contained liquid is hard to evaporate.

[0002]

2. Description of the Related Art Conventionally, for example, in an application part of a liquid applicator such as cologne liquid, a rotation is made to the ejection port of a cylindrical application part body in which a tip end ejection port and a base end introduction port are connected by a liquid passage. A flexible ball is pressed from the inside by a spring to keep it in a normally closed state.In use, the ball is applied to an object to be coated, such as the skin, and is rotated, so that the ball surface on which the cologne liquid is adhered in the liquid passage is externalized. There is a structure in which it is rotationally displaced and applied little by little to the object to be coated.

[0003]

In the above liquid applicator, it is difficult to maintain the airtightness of the inside of the main body because the application ball is pressed against the discharge port from the inside to close the inside and outside of the applicator. There was a problem that the cologne solution was easily evaporated and scattered.

An object of the present invention is to solve the above problems, and to solve the problems, it is an object of the present invention to reduce the amount of evaporation of liquid such as cologne liquid contained therein.
Another object of the present invention is to simplify the structure and reduce the manufacturing cost. A further object of the present invention is to provide an application part of a liquid applicator that can prevent a valve mechanism provided inside from being blocked.

[0005]

In order to achieve the above-mentioned object, the present invention is, firstly, the application part of an applicator which is configured so that the liquid contained therein is pushed out toward the application part by an extrusion mechanism. And a cylindrical coating portion main body provided with a liquid passage that communicates the discharge port at the tip end and the introduction port at the base end, and is rotatably supported on the inner surface of the discharge port and is biased inside the discharge port by a biasing member. It is composed of a spherical coating ball pressed from and a valve member pressed from the inside to the inlet by a biasing member, and the valve member is a predetermined value or more through the liquid by the pushing mechanism. When receiving a pressing force, the introduction port opens.

Secondly, according to the present invention, a ball valve is used as the valve member, and both ends of the elastic spring for pressing the coating ball and the ball valve simultaneously against the discharge port and the introduction port are connected to the coating ball and the ball valve. To the liquid passage.

[0007]

In the case of the first configuration, the liquid pressed by the pushing mechanism displaces the valve member against the urging force of the urging member by the pressing force, thereby opening the inlet port. And then flows into the liquid passage. Here, if the coating ball is pressed against an object to be coated such as skin and rubs so as to rotate the coating ball, the inner surface portion of the coating ball to which the liquid adheres is displaced to the outside, and the liquid is applied to the object to be coated. To be done. And
In the application unit, when the extrusion mechanism is not operated, the ejection port is closed by the application ball, and the introduction port is closed by the valve member. Therefore, the liquid contained in the applicator is highly airtight. The property is maintained and it is hard to evaporate and scatter.

In the case of the second configuration,
Due to its structure, it is possible to use the minimum number of elastic springs, and because both ends are connected to the coating ball and the ball valve, the structure is simple and the manufacturing cost can be reduced. Become. Further, in the ball valve, even if the closing surface changes due to the rotation due to the opening / closing operation, the closing surface, which is a part of the spherical surface, is uniform, and thus the closing failure is unlikely to occur. Further, when one of the coated ball and the ball valve is displaced in the opening direction, the other is elastically urged in the closing direction, so that higher airtightness can be obtained.

Since the operating portion 16 is difficult to rotate with respect to the advancing portion 15, the slit 20 is provided.

Next, a method of using the applicator 1 will be described.
First, by rotating the operating portion 16 of the pushing mechanism 5, the eau de Cologne liquid a which has received a predetermined pressing force causes the ball valve 12 of the applying portion 3 to resist the urging force of the elastic spring 13 and the valve seat. It is pushed up from 8a and flows into the liquid passage 9 through the introduction port 8. It should be noted that after the operation of the operation portion 16 is stopped, the pressing force is no longer received, so the elastic spring 1
The ball valve 12 again closes the inlet 8 by the urging force of 3.
When the coordinating liquid a enters the liquid passage 9 as described above, the coating ball 11 is pressed against an object to be coated such as the skin and rubbed so as to rotate the coordinating liquid a.
Since the inner surface portion of the coating ball 11 to which is adhered moves to the outside, the eau de Cologne liquid a can be applied to the object to be coated.

The present invention is not limited to the above embodiment, and for example, the applicator 1 to which the applicator 3 is applied.
May be used not only for cologne a, but also for other perfumes or liquid medicines for soothing, the pushing mechanism 5 may be changed to a different structure, and the outer cylinder 2 is different from the cylindrical shape. It may be shaped. Furthermore, the biasing member is the elastic spring 1.
3 is not used, the coating ball 11 and the ball valve 12 are connected to the discharge port 7
As long as it biases the inside and the outside of the inlet 8 from the inside, for example, not only the coating ball 11 and the ball valve 12 may be separately provided, but also other biasing members such as a leaf spring and rubber. You may change to. Further, the valve member may be a conical one instead of the spherical ball valve 12, or a leaf spring which is a biasing member fixed near the inlet 8 and is provided with a rubber packing that abuts the inlet from the inside. Good.

[0020]

As described above, according to the present invention, in addition to closing the discharge port with the coating ball and closing the introduction port with the valve member, the liquid inside maintains a high airtightness. The effect is that it is hard to evaporate and scatter.

When the application ball and the ball valve block the discharge port and the introduction port by the urging force of the elastic spring of the present invention, only one elastic spring is used.
The structure is simple and the manufacturing cost can be reduced because it is only necessary to place the applied ball and the ball valve in contact with each other, and when one of the applied ball and the ball valve is displaced in the opening direction, the other is resilient in the closing direction. Since it is urged, it has an effect of obtaining higher airtightness.

Further, when the ball valve of the present invention is used, even if the closing surface changes due to the opening / closing operation and the closing surface changes, the closing surface, which is a part of the spherical surface, is uniform, so that poor closing is unlikely to occur. Produce an effect.
