It has an operating lever and a valve body that opens and closes a discharge hole provided in the middle of the communication path in synchronization with the operation of the operating lever, and when the operating lever is in the first position, the sharp body The tip of the pointed body is supported at a position protruding from the cylinder mounting section, and the valve body is supported at a position that opens the exhaust hole, and when the operating lever is in the second position, the tip of the pointed body is supported at a position protruding from the cylinder mounting section. The valve body is supported in a retreating position and is also supported in a position that closes the exhaust hole, and when the operating lever is in the first position, the cylinder is attached to the cylinder mounting part, thereby discharging to the sealing plate of the cylinder. The discharge hole is characterized in that the discharge hole is sealed by forming a hole and pressing the seal member against a sealing plate.

<Example> Hereinafter, an example of the present invention will be specifically described with reference to the drawings.

FIG. 1 is a partially cutaway side view showing an example in which the pouring device according to the present invention is used in a tabletop beer barrel for home use, and FIG. 2 is an enlarged sectional view of the main part. This pouring device injects carbon dioxide gas into the beer barrel 1.
Beer B stored in a beer barrel 1 is poured out through a vinyl pipe 2. This pouring device has a main body 7 equipped with a cylindrical portion 6 attached to a stopper 5 assembled to the mouth portion 3 of the barrel 1 via a packing member 4. The main body 7 is made of synthetic resin or the like in order to reduce its weight, and has a cylinder mounting hole 9 at one end to which a small cylinder 8 filled with liquefied carbon dioxide (75 kg/cm ² ) can be removably attached. is provided. The cylinder mounting hole 9 is formed with a female thread, and the tip of the cylinder 8 is formed with a male thread. By screwing the tip of the cylinder 8 into the mounting hole 9, the cylinder 8 is supported in a diagonally downward direction with respect to the main body 7.

Further, the main body 7 is provided with a cylinder opening needle (sharp object) 10 whose tip can protrude into and out of the cylinder mounting hole 9. The needle 10 is assembled to a stem 12 that is slidably and tightly fitted into a cylinder portion 11 formed in the main body 7 coaxially with the cylinder mounting hole 9. At the tip of the stem 12, a ring-shaped sealing member 13 made of soft rubber such as butyl rubber surrounds the tip of the needle 10.
is assembled.

An operating lever 14 for operating the needle 10 is arranged at the rear end of the stem 12. The lever 14 is bent into an L-shape, one end of which is pivotally supported via a pin 16 in a lever mounting hole 15 formed diametrically through the rear end of the stem 12, and the other end of the lever 14 is bent into an L-shape. A window 17 provided in the main body 7 is removed to protrude to the outside. A cam 18 is formed at one end of the lever 14.
Normally (when the operating lever 14 is in the first position),
The stem 12 is held at a position where the tip of the cylinder opening needle 10 projects into the cylinder mounting hole 9. Move the lever 14 to the second position around the pin 16.
When the lever is rotated counterclockwise in the drawing to move to the second position, the cam 18 engages with the rear wall of the lever mounting hole 15, and the stem 12 is slid rearward. As a result, the tip of the needle 10 is retracted from the cylinder mounting hole 9.

Further, a gas communication passage 19 is formed in the main body 7 to connect the cylinder mounting hole 9 and the inside of the cylindrical portion 6 via the cylinder portion 11 . An exhaust hole 20 is formed in the middle of the gas communication path 19, and a valve body 21 made of a rubber material, for example, is arranged at the position of the exhaust hole 20 to open and close the exhaust hole 20. The valve body 21 is always resiliently biased in the direction of opening the exhaust hole 20 by a first compression coil spring 22 disposed across the communication path 19. Further, the valve body 21 is connected to the operating lever 14 via a second compression coil spring 23. Note that the elastic force of the first compression coil spring 22 is set lower than the elastic force of the second compression coil spring 23. Further, each of the springs 22 and 23 also functions to automatically return the operating lever 14.

Under normal conditions (when the operating lever 14 is in the first position), the valve body 21 is connected to the first compression coil spring 22.
It is held in the position where the exhaust hole 20 is opened by the elastic force of. Connect the lever 14 to the pin 1
6 in the counterclockwise direction in Fig. 2,
When the valve body 21 is moved to the second position, the elastic force of the second compression coil spring 23 holds the valve body 21 in a position where the exhaust hole 20 is closed.

Next, the operation of the pouring device having the above configuration will be explained.

First, as shown in FIG. 3, the cylinder 8 is installed in the cylinder installation hole 9 of the main body 7. When the cylinder is attached, the tip of the cylinder opening needle 10 is inserted into the sealing plate 8A of the cylinder 8, as shown in FIG. 4, and a small discharge hole 8a is formed in the sealing plate 8A. At this time, the sealing member 13 is placed in pressure contact with the sealing plate 8A and seals the discharge hole 8a, so that the discharge of carbon dioxide gas from the discharge hole 8a is prevented. Therefore, carbon dioxide gas is not supplied into the barrel 1.

Next, as shown in FIG. 5, when the operating lever 14 is pushed down toward the barrel 1 side (rotated counterclockwise in FIG. 5), the valve body 21 also blocks the exhaust hole 20. Then, as shown in FIG.
When pushed down further, the stem 12 is slid rearward, and thereby the tip of the cylinder opening needle 10 is also moved back and pulled out from the sealing plate 8A. At this time, the sealing member 13 is separated from the sealing plate 8A as shown in FIG.
1. The gas is supplied into the barrel 1 through the gas communication path 19 and the inside of the cylindrical portion 6.

By supplying carbon dioxide gas into the barrel 1, the beer B in the barrel 1 can be poured out through the vinyl pipe 2 by the pressure of this carbon dioxide gas.

Then, as shown in FIG. 8, when the push-down operation of the operating lever 14 is released, the lever 14 is
It is urged to rotate in the clockwise direction in FIG. 8 by the elastic force of the second compression coil springs 22 and 23.
As a result, the stem 12 slides forward, the sealing member 13 comes into pressure contact with the sealing plate 8A again, and the discharge hole 8a
The valve body 21 then closes the exhaust hole 2.
Open 0. In this way, when the valve body 21 opens the exhaust hole 20, the carbon dioxide remaining in the barrel 1 is discharged into the atmosphere through the cylindrical portion 6, the gas communication passage 19 and the exhaust hole 20 as shown by the arrow in FIG. released inside.

Note that the push-down state of the operating lever 14 is controlled within the range of the position shown in FIG. 5 and the position shown in FIG. 6, and the amount of thrust of the tip of the cylinder opening needle 10 into the discharge hole 8a is controlled. Therefore, the amount of carbon dioxide gas discharged from the discharge hole 8a can be easily adjusted. Therefore, the amount of beer B dispensed can be easily adjusted.

As described above, according to the above embodiment, when the supply of carbon dioxide gas into the barrel 1 is stopped (the push-down operation of the operating lever 14 is released), the carbon dioxide gas remaining in the barrel 1 is released into the atmosphere. Since the pressure inside the barrel 1 decreases, the pouring of beer B can be stopped instantaneously. Therefore, there is no dripping phenomenon of the beer B, and a desired amount of the beer B can be accurately poured out.

In addition, the valve body 21 is configured to receive the elastic force of the second compression coil spring 23 and block the exhaust hole 20, so that if an external impact is applied to the barrel 1 during beer pouring, , since the valve body 21 immediately opens the exhaust hole 20 due to the impact, the beer B
The dispensing can be stopped instantly. Therefore, even if the outlet end of the vinyl pipe 2 is displaced due to the above-mentioned impact, beer B can be prevented from leaking from the pipe 2 and spilling onto a table or the like.

Also, since carbon dioxide gas is about 1.5 times heavier than air, once carbon dioxide gas is injected into barrel 1,
Even if the carbon dioxide inside the barrel 1 is released into the atmosphere, the same pressure as the atmospheric pressure remains inside the barrel 1. Therefore, the beer B in the barrel 1 is difficult to lose its flavor, and the taste of beer B can be maintained.

In addition, beer B can be dispensed by simply pushing the operating lever 14 toward the barrel 1, and beer B can be dispensed automatically by releasing the pushing operation of the operating lever 14. The brewing machine can be stopped, and the operation of dispensing beer B can be easily performed.

Further, since the cylinder 8 is configured to be mounted on the main body 7 by screwing its tip into the cylinder mounting hole 9 of the main body 7, the cylinder 8 can be easily replaced.

In addition, in the present invention, the exhaust hole 20 can be opened and closed reliably even if the valve body is made of a synthetic resin sphere.

Furthermore, the present invention can also be used for large-capacity commercial beer kegs if a large-capacity cylinder is used.

Furthermore, the present invention is also applicable to pouring out a material to be poured made of gas, powder, or the like.

<Effects of the invention> As described above, according to the invention, when the supply of pressurized gas into the container is stopped, the pressurized gas remaining in the container is released into the atmosphere through the exhaust hole, and the inside of the container is Since the pressure decreases, the pouring of the material to be poured can be stopped instantaneously. Therefore, the dripping phenomenon of the material to be poured out does not occur, and the desired amount of the material to be poured out can be accurately poured out.
