Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to an extraction container which is characterized by opening and closing a valve provided at a mouth portion and solving a coating problem caused by a foam coating body.

[Conventional technology]

Conventionally, many extraction containers are provided with a cap at the container opening, and the attachment passage of the pouring plug provided inside the container opening is closed by a projection or the like provided inside the cap when the cap is attached. Further, as another pouring container, there is one in which a valve is provided in a stopper body fitted in a container mouth portion, and the valve is opened and closed by the action of a spring.

However, in such a type of pour-out container, since the pour-out path is opened and closed on the inner surface of the cap, when the content of the container is liquid, the cap is repeatedly opened and closed,
The content liquid adheres to the inner surface of the cap, which in turn adheres to the vicinity of the mouth of the container, resulting in contamination of the surroundings.

Further, in the case where the spring is used as described above, the spring intervenes in the pouring path, so that the extraction of the liquid may be hindered, or if the spring is made of iron, it may rust and deteriorate the contents.

In order to solve such a problem, a valve seat body is provided in the container body, and a valve body urged by a spring in a direction away from the valve seat body is provided, and a woven cloth applicator is further provided on the valve body. When the cap is attached, the inside of the cap presses the valve body against the urging force of the spring to close the pouring passage provided in the valve seat body (actually opened 57-154663). Alternatively, a valve seat body is fitted to the mouth tube portion of the container body, and a valve body is provided which is biased by a spring in a direction away from the valve seat body, and the valve body has elasticity. A coating surface made of hard synthetic resin and having multiple outlets is provided, and when the cap is attached, the inner surface of the cap presses the valve body against the biasing force of the spring to close the pouring path provided in the valve seat body. And close the spring to the inside of the container. Etc. have been accommodated in the spring chamber and dispensing container (see JP Utility Model 52-13196) has been devised.

[Problems to be solved by the device]

In the one disclosed in Japanese Utility Model Laid-Open No. 57-154663, since the woven cloth is used as the application body, the liquid is evenly leached from the application body, so that sufficient application is possible. However, it becomes difficult to apply evenly because the applied body is gradually crushed.
Moreover, when the valve is open, the spout provided in the valve seat communicates with the spring chamber, so that the spring intervenes in the spout to prevent the liquid from pouring out or the spring to be made of iron. If it is, there is a risk of rusting and altering the contents.

Further, in JP-B-52-13196, since the coating portion is made of a hard synthetic resin having elasticity, when the liquid is coated, the liquid is flowed through a plurality of outlets formed on the coating surface. Since it is caused to flow out, the application of the liquid tends to be localized, and it is impossible to apply the liquid evenly.

[Means for solving the problem]

The present invention has been made in view of such a conventional problem, and by blocking the pouring path in the container mouth without directly touching the cap, it adheres to the vicinity of the container mouth and stains the surroundings. In addition, the spring is blocked from the spouting path to prevent the contents from deteriorating due to the rusting of the spring. In addition, a foam with good leaching of the liquid is used as the coating body, and the coating surface is prevented from being crushed. This is a pouring container that can be applied evenly and continuously.

That is, the present invention has a container mouth portion 2a formed in the container mouth cylinder portion 2 and a spout pipe 5 fitted in the container mouth portion 2a and having a spout passage 7 and a valve seat portion 5a formed therein. Valve seat 3
And a valve body 11 provided with a valve portion 12 for opening and closing the pouring path 7,
A foam application body 20 provided in a liquid chamber 29 formed on the valve body 11, a spring 14 for urging the valve body 11 away from the valve seat body 3, and the container. Mouth tube 2
Detachably attached to the spring 14
And a cap 25 configured to press the valve body 11 against the valve seat body 3 side against the biasing force of the valve body 11, and the valve body 11 is liquid-tight and slidable on the spout pipe 5 of the valve seat body 3. A sliding cylinder 10 that is movably fitted is provided, and a spring chamber 8 that is closed to the inside of the container is formed around the spout tube 5. Further, in the liquid chamber 29, up to the vicinity of the coating body 20. The pouring container was provided with the extending support rod 28.

[Action]

When the cap 25 is closed, the valve body 11 is pushed by the cap 25 and moves toward the valve seat 3 side against the spring 14.
As a result, the valve portion 12 comes into contact with the outlet of the spout pipe 5 to shut off the spout passage 7.

When the cap 25 is opened, the valve element 11 is moved by the spring 14 in a direction away from the valve seat element 3, and the valve portion
12 separates from the outlet of the spout pipe 5 and opens the spout path 7.
Since the spring 14 is provided inside the spring chamber 8 which is closed inside the container and opened outside the container, the spring 14 does not intervene in the spout passage 7.

Furthermore, the application body 20 formed of foam is a support rod.
It is held by 28 and prevents the coated body from being crushed during coating, and the liquid is evenly leached from the foamed body.
