BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an applicator having a valve interposed between a brush and a liquid chamber. Here, examples of the liquid include a writing liquid such as black ink, paint, ink, a cosmetic liquid such as an eyeliner and a lip color, a liquid seasoning, a machine oil, and a cleaning liquid.

[0002]

2. Description of the Related Art There are various types of applicators such as those described above in which a valve is opened by a rear end knock and those in which a valve is opened by a side knock. Normally, the liquid that is led out by opening the valve is temporarily stored in a urethane porous body or the like disposed in front of the valve, and is used for use with the brush.

[0003]

The required amount of the liquid that has been led out by opening the valve must be promptly supplied to the brush, and the amount temporarily stored in front of the valve is ensured without leakage. Must be stored. At first glance, it is surprisingly difficult to actually satisfy these conditions that seem to be satisfied. For example, it is common practice to promptly supply liquid by inserting a pipe from the rear end of the brush to the middle, but without causing liquid leakage or breaking the brush. It is difficult to allow the liquid to easily pass through the pipe body without occurring. It is also difficult to supply the temporarily stored liquid to the brush ears sufficiently, and to make the storage structure such that the liquid does not leak.

[0004]

SUMMARY OF THE INVENTION The present invention relates to an applicator having a valve interposed between a brush and a liquid chamber, the tubular body covering a rear outer wall of the brush and preventing the brush from falling off. A liquid reservoir groove is provided on the inner wall of this, and this tubular body is attached to the tip of the front shaft,
In addition, a stopper having a pipe inserted therethrough from the rear end to the middle of the brush ear is fixed inside the tip shaft, the brush ear is supported by the stopper, and the brush head is positioned. And a liquid reservoir space for storing the liquid without capillary force is formed between the valve and the valve.The pipe body is opened in the liquid reservoir space, and the liquid is supplied between the stopper and the tip shaft by the capillary force. The gist of the present invention is to provide an applicator which is provided with a liquid reservoir gap that can be held, opens the liquid reservoir gap into the liquid reservoir space, and further communicates the liquid reservoir gap with the liquid reservoir groove of the tubular body.

[0005]

The liquid led to the liquid storage space with the valve opened may be supplied to the brush through a pipe.
There is also a portion that is supplied from a liquid reservoir groove on the inner wall of the tubular body that passes through the liquid reservoir gap between the shaft and the front shaft and communicates with the liquid reservoir gap, to the brush ear existing inside the liquid reservoir groove. Which is larger depends on the momentum of derivation, etc., but a sufficient amount of liquid is supplied to the brush ears through these two paths. In addition, the liquid stored in the liquid storage space, the liquid storage gap, and the liquid storage groove leaks due to the capillary force generated by the liquid storage gap and the liquid storage groove even if the liquid storage space stores a large amount of liquid regardless of the capillary force. Is prevented.
Furthermore, when the liquid is consumed in the brush head portion, first, the liquid stored in the liquid reservoir groove is supplied to the brush head. At this time, even if the liquid stored in the liquid storage gap or liquid storage space is supplied through the pipe body, the brush ears, the liquid storage groove, the liquid storage gap, and the liquid storage space have one sealed structure, Since the liquid component passing through the pipe body moves from the liquid storage groove to the liquid storage space through the liquid storage gap, it is substantially the same as the liquid stored in the liquid storage groove being supplied to the brush.

[0006] When the amount of liquid in the liquid reservoir groove decreases, a gap is formed between the inner wall of the tubular body and the brush. The air was present in place of the liquid, and this air gradually came to the rear. If the liquid in the reservoir groove is fully utilized, the air will eventually be present in the reservoir gap. In this case, the liquid is supplied from the pipe to the brush as much as the liquid in the liquid reservoir gap recedes into the liquid reservoir space. This is due to the fact that the brush ears, liquid reservoir groove, liquid reservoir gap, and liquid reservoir space have been opened. Then, finally, the liquid in the liquid storage space is sufficiently supplied to the brush ears.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 1, the brush ear 1 is fixed to the brush by welding or bonding, and its rear end is pushed by a tubular body 2 to prevent the brush head from falling off. The tubular body 2 has a liquid reservoir groove 2a (see FIGS. 1A and 2). In the illustrated embodiment, the brushhead 1 is pushed by the rear end of the rib 2b forming the liquid reservoir groove 2a. However, it is appropriate if the liquid reservoir groove 2a communicates with a liquid reservoir gap described later. The tubular body 2 is attached to the front shaft 3 by press fitting or the like.

A stopper 5 to which a pipe 4 is attached is fixed inside the front shaft 3. The stopper 5 supports the brush 1 so that the brush 1 is positioned. The stopper 5 has a concave portion 5a, and the concave portion 5a forms a gap between the stopper 5 and the front shaft 3 (see FIG. 3). The recess 5 is a liquid reservoir gap in the present example. Of course, the liquid reservoir gap can also be formed by making the inner wall of the front shaft 3 irregular.

An elastic member 6 such as a coil spring is supported on the rear wall of the stopper 5. The repelling member 6 urges the valve body 7 so as to contact the valve seat 8. The valve in this embodiment is composed of the resilient member 6, the valve body 7, and the valve seat 8, but there are various valve structures, and the valve structure is appropriately adopted. Further, in this embodiment, the valve seat 8 is provided on the front shaft 3, but a suitable member can be appropriately integrated or separated, and a separate valve seat member may be used.

Reference numeral 9 denotes a bellows member which is self-elastically expanded and contracted attached to the front shaft 3, reference numeral 10 denotes a pressing body mounted to the bellows member 9, reference numeral 11 denotes a front shaft which projects and fixes the front shaft 3, 11a is an inner wall step portion of the front shaft for regulating the moving amount of the pressing body 10, 12 is a center shaft for mounting the front shaft 11 and supporting the pressing body 10, and 13 is a main part of the liquid chamber. The liquid tank 13a is a liquid tank 13
A shoulder for determining the amount of connection to the pressing body 10, 14 is a ball for stirring liquid, 15 is a connection shaft which is detachably screwed to the front shaft 11, and 16 is a connection shaft. 15 is a rear shaft mounted by press fitting or the like, 17 is a repelling member such as a coil spring, 18 is a knocking body biased by the repelling member 17, and 19 is an outer cap 19a and an inner cap. This is a cap made of 19b.

That is, the present embodiment is an example of a rear end knock type. In use, first, the screw engagement between the front shaft 11 and the connection shaft 15 is released, and the liquid tank 13 is attached to the pressing body 10.
When the front shaft 11 and the connection shaft 15 are screwed into the state shown in the drawing and a pressing force is applied to the knock body 18, the knock body 18 comes into contact with the rear end of the liquid tank 13 and the liquid tank 13
And the pressing body 10 move forward while shrinking and deforming the bellows member 9 and thus reducing the volume of the liquid chamber.
The pressing body 10 comes into contact with the valve body 2, and the valve body 2 moves forward to open the valve.

When the valve is opened, the liquid is discharged to the space 20 where the repelling member 6 is located. The space 20 is a liquid storage space in the present embodiment. The recess 5 a of the stopper 5, that is, the gap between the reservoirs communicates with the reservoir space 20.
As described above, the liquid reservoir groove 2a of the tubular body 2 is in communication with a. In FIG. 2, the space between the ribs 2b is widened at two places. This is the portion indicated by reference numeral 2c. This portion 2c allows the air to penetrate faster than the liquid reservoir groove 2a, so that {the brush head, the liquid reservoir groove, the liquid reservoir gap, the liquid reservoir space} has a quick open structure. In this case, even if the liquid is stored in the liquid storage groove 2a, the liquid is divided into a part that is replaced by the concave part 5a into the liquid storage space 20 and a part that is supplied to the brush head 1 from the liquid storage groove 2a. Used well.

In addition to the above, various modifications can be made without departing from the gist of the invention. For example, a side knock type may be used, or the arrangement of the valve body 7 and the valve seat 8 may be reversed so that the valve seat 8 moves instead of moving the valve body 7.
