[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container for quantitatively applying a hairdressing agent, a hair dye, various chemicals, and the like.

[0002]

2. Description of the Related Art Conventionally, coating containers for accommodating hair coloring materials, hair dyes, various chemicals, and the like are already well known. For example, small holes or liquid-permeable It is equipped with an application plug having an application brush, application sponge, etc., and the body of the bottle is squeezed so that the liquid in the bottle is pressure-poured out from the application stopper and applied to the essential parts with the application stopper. It has become.

[0003]

[Problems to be solved by the invention] However, when a certain amount of pouring cannot be obtained, and when the internal pressure fluctuates depending on the degree of squeezing or being warmed by the palm, sometimes the overshoot and sometimes the shortage occur. Occurs. The present invention is intended to solve the conventional drawbacks, and at the same time, is intended to reduce the size of the metering application plug as much as possible and to improve the airtightness and watertightness of the spout.

[0004]

According to the present invention, a fixed amount application plug 2 is fitted to a mouth and neck portion 1a of a squeeze type bottle 1, and the fixed amount application plug has a measuring chamber 2b inside thereof. A plug body 2a is fitted to the neck 1a in an airtight manner, and a pipe 3 is suspended from the plug body into the bottle 1 to allow the pipe to communicate with the measuring chamber 2b and to be applied to the plug body 2a. A head 2c is provided, and an elastic inward skirt portion 2q that forms a spout 2d is provided at the tip of the coating head. Slightly protruding, the valve cylinder has a valve part in the middle of the outer circumference corresponding to the inner edge of its spout 2d.
2f, the valve portion is seated and closed at the inner edge of the spout, and a valve cylinder urging means is provided to urge the valve portion in the seating closing direction, and the valve seat 2g facing downward at the distal end portion in the cylinder. A short rod-shaped valve body 2h is seated and closed on the valve seat, and the tip of the rod-shaped valve body is slightly pushed out from the tip of the valve cylinder so as to be able to open the valve. Elastic piece at end
A support ring 2j is attached to the other end of the elastic piece, and the support ring is fitted and fixed in place in the valve cylinder 2e. 2h is biased in the seated closing direction.

[0005]

[Effects] The configuration is as described above.
The body 1b of the bottle 1 containing the coating liquid is squeezed in the upright posture. Thereby, the coating liquid in the bottle 1 is supplied to the measuring chamber 2b of the fixed amount coating plug 2 through the pipe 3. At this time, the valve portion 2f of the valve cylinder 2e closes the spout 2d, and the rod-shaped valve body
Since the valve 2h is seated and closed on the valve seat 2g, the air in the fixed amount application plug 2 is pressurized simultaneously with the supply of the application liquid. After supplying a predetermined amount or more of the coating liquid, when the squeezing of the body is released, since the internal pressure of the fixed amount coating plug 2 is initially higher than the internal pressure of the bottle 1, excess coating liquid is supplied to the bottle 1. After being pulled back, a predetermined amount of the coating liquid remains in the fixed amount coating plug 2, that is, in the measuring chamber 2b.
Next, the whole is inverted, and the coating liquid in the measuring chamber 2b is transferred to the coating head 2c, and the rod-shaped valve element 2h is brought into contact with a point to be coated, and the rod-shaped valve element, and subsequently the valve cylinder 2e Press down. Accordingly, first, the rod-shaped valve element 2h opens to open the valve cylinder 2e, and the valve cylinder communicates the air in the bottle 1 with the outside air through the air in the measuring chamber 2b and the pipe 3. Then, the internal pressure of the fixed amount application plug 2 and the bottle 1 is brought to the atmospheric pressure. Subsequently, the valve portion 2f of the valve cylinder opens the outlet 2d, and the coating head is opened from the outlet.
The coating solution in 2c flows out naturally. This outflow can be performed continuously or every time the rod-shaped valve element 2h and the valve cylinder 2e are pushed in as long as the application liquid is present in the application head 2c. In other words, a predetermined amount can be continuously or subdivided and discharged.
You can rub with 2c. Needless to say, it is also possible to similarly use the coating liquid once received by the palm or the like. By the way, at the time of the above-mentioned application and the like, the inside of the bottle 1 may be warmed by the palm to expand the application liquid and the air therein, thereby increasing the internal pressure. However, since the inside of the bottle 1 and the inside of the fixed amount application plug 2 are communicated with each other by the pipe 3, both are at equal pressure, and in the inverted posture, only the air moves through the pipe 3 and there is no movement of the application liquid. .

[0007]

According to the present invention, by squeezing and releasing the bottle 1 in the upright posture, the application liquid can be accurately measured and classified into a predetermined amount by the fixed amount application plug 2, and thereafter, in the inverted posture, the rod shape By pushing the valve body 2h and the valve cylinder 2e, and opening the valve cylinder 2e and the spout 2d, the predetermined amount of the coating liquid can be continuously or subdivided from the spout 2d and flow out, and In that case, prior to the pushing of the valve cylinder 2e that opens the injection port 2d, the rod-shaped valve body 2h is pushed in to open the valve cylinder 2e, and the bottle in the fixed quantity application plug 2 is opened via the air and the pipe 3. 1
Since the inside air is communicated with the outside air, the internal pressure of the fixed quantity application plug 2 and the bottle 1 can be assimilated to the atmospheric pressure. Therefore, the internal pressure can always be set to the atmospheric pressure at the time of dispensing, and the quantitative application is performed at the time of the dispensing. Since the application liquid once measured by the stopper 2 is allowed to flow naturally, there is no occurrence of excessive or insufficient discharge.
Depending on the degree of squeezing or being warmed in the palm,
There will not be too much or too little. In addition, in the inverted posture, even if the inside of the bottle 1 is warmed by the palm and the application liquid and air inside expand, and the internal pressure rises, the inside of the bottle 1 and the inside of the fixed amount application plug 2 become equal pressure by the pipe 3, Moreover, since only the air moves through the pipe 3 and the coating liquid does not move, the amount of the coating liquid once measured does not increase or decrease,
It is always possible to obtain a precise and constant amount of application. Further, a downwardly facing valve seat 2g is formed at the distal end inside the valve cylinder 2e, a short rod-shaped valve element 2h is seated and closed on the valve seat, and the distal end of the rod-shaped valve element is pushed in from the distal end of the valve cylinder to open. One end of an elastic piece 2i is connected to the rear end of the rod-shaped valve element 2h, and a support ring 2j is attached to the other end of the elastic piece, and the support ring is fitted in a proper position in the valve cylinder 2e. Since the rod-shaped valve 2h is urged in the seating and closing direction by the elastic piece 2i, the rod-shaped valve
Etc. can be stored in the valve cylinder 2e, and do not protrude into the space inside the fixed amount application plug and occupy the space.Therefore, unnecessary space can be eliminated, and the size of the fixed amount application plug can be reduced as much as possible.
It can be portable and convenient to use. In addition, since the periphery of the outlet 2d is an elastic inward skirt portion 2q, the valve portion 2f of the valve cylinder 2e can be brought into close contact with the inner edge of the outlet, ensuring airtightness and watertightness, and ensuring accurate operation. Can be obtained.
