Description

Akirayanagi Injection device technology field The present invention uses a pressure of a pressurized fluid such as carbon dioxide gas to eject an injectable material such as beer or cola stored in a container. A first sliding operation rod for opening the sealing plate of the cylinder filled with the pressurized fluid and opening and closing the opened sealing plate, and the container and the outside of the container. The present invention relates to a dispensing device that facilitates a dispensing operation by operating a second sliding operation rod having a valve body provided at a tip thereof for opening and closing a communication passage to be operated in conjunction with an i operation lever. Background Art Conventionally, there has been known a dispensing apparatus that dispenses a beer cola in a container using high-pressure gas. The pouring device includes, for example, an injection pipe for injecting a pressurized fluid such as carbon dioxide gas into the container and a beer in the container to a lid attached to an upper opening of the container and closing the opening. In addition to providing an injection pipe leading to the outside, a holder for mounting the cylinder filled with the pressurized fluid to the injection pipe, and a valve device for opening and closing the cylinder are provided, and the valve device is operated. By the above, the pressurized fluid is injected into the container, and the beer is poured into the container by the pressure. It is made to pour out from the departure pipe. The pouring device having such a configuration does not leak beer as compared with the pouring device in which the nozzle in the pouring and the valve device for opening and closing the nozzle are provided at the lower part of the container as described above. Moreover, the pouring operation can be easily performed.

By the way, in such a pouring device, the pouring tube is not provided with any opening / closing means, and the inside of the container is always kept in communication with the atmosphere via the pouring tube. Therefore, for example, there is a disadvantage that the beer inside flows out of the injection pipe when the container falls down or tilts under external force. Further, since the beer in the container comes into contact with the atmosphere via the pouring pipe, there is a disadvantage that carbon dioxide in the beer diffuses into the atmosphere and the flavor is easily impaired. -Therefore, if a valve device that opens and closes the above pouring is provided in order to eliminate such drawbacks, it is necessary to operate two valve devices when pouring out the above-mentioned beer. The disadvantage is that it takes time and effort.

If the closing operation of the dispensing device is neglected, the pressure inside the container becomes high due to the pressurized fluid, thereby causing the beer to go outside from the valve device on the dispensing tube side. There is a risk of leakage, and the effect of the pouring device S configured to pour beer with such pressurized fluid is reduced by half. In addition, when the beer pouring operation is performed in a state where the pressure in the container is high as described above, the beer may be spouted suddenly.

In view of the above situation, the present invention makes it possible to easily perform a pouring operation using a pressurized fluid for an object to be poured stored in a container. When the pouring operation is not performed, the inside of the container is kept closed to prevent the outflow of the to-be-outjected material and the alteration of the to-be-injected material due to coming into contact with the atmosphere, and DISCLOSURE OF THE INVENTION An object of the present invention is to provide a pouring device ′ capable of reliably preventing the pressure in a container from being increased by a pressurized fluid.
