DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the present invention, wherein when beer in a beer barrel becomes empty or nearly empty, even if the last beer is poured out, beer foam and carbon dioxide gas flow out to a mug or the like. The present invention relates to a device that can prevent the occurrence of a problem.

[0002]

2. Description of the Related Art Carbon dioxide is dissolved in beer stored in a beer barrel in advance. When selling beer, carbon dioxide is further supplied into the barrel to extrude the beer, and the beer is cooled down through a server. And distribute to mugs.

[0005] That is, as shown in FIG. 5, a carbon dioxide gas cylinder 11 is connected to a beer barrel 10, and the inside of the barrel is maintained at a constant pressure via a pressure adjusting device 12. Then, the beer in the barrel is pushed out toward the server 13 by the pressure.

[0004] When the beer in the beer barrel is empty or nearly empty, the carbon dioxide gas reaches the bottom of the barrel,
Since it comes out from the beer outlet pipe 3 to the pipe line 15, the curan 1
If 8 is open, beer foam will be poured into the mug, or high-pressure carbon dioxide will erupt. Therefore, in order to prevent the beer foam from being poured into the mug or the high-pressure carbon dioxide from being blown out, for example, the method disclosed in

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The preferred embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a partial sectional view showing a beer foam outflow prevention device of the present invention. The beer foam outflow prevention device has a suction member 1A having a beer suction port 1A on a lower side and a seal portion 1B on an upper side. 1 and a buoyancy member 2 having an airtight matching portion 2B with a float 2A and the seal portion 1B
It is composed of

The outflow of beer foam is prevented by the interaction between the suction member 1 and the buoyancy member 2.
Before the relationship between the two, the beer barrel 10 will be described first.

[0011] That is, when selling beer, the head 1
The beer outlet pipe 3 having the upper end 9 is inserted into the beer barrel 10. Then, the lower part of the pressure adjusting device is fitted into the upper lid of the beer barrel 10 to fix the beer outlet pipe 3 so that the beer in the barrel can be pushed out toward the server.

When the beer outlet pipe 3 is fixed, the lower end of the beer outlet pipe 3 and the bottom of the beer barrel 10 are positioned at an appropriate distance so that the lower end does not contact the bottom of the beer barrel 10 during positioning. have. However, after completion of the fixing, the beer outlet pipe 3 is lowered simultaneously with the fixing so that the beer in the barrel can be consumed as much as possible, and the lower end thereof is positioned just below the barrel bottom. And the bottom itself of the beer barrel 10 also has an inclined surface which descends toward the central beer outlet pipe 3.

By the way, since the suction member 1 is airtightly fitted to the lower end of the beer outlet pipe 3, it is not necessary to care about its position as long as it is merely inserted into the beer outlet pipe 3. The lowering of the beer outlet pipe 3 causes it to hit the bottom of the beer barrel 10, so that the suction member 1 is easily positioned at the same position in the beer barrel 10 at all times. Therefore, the beer suction port 1A below the suction member 1 is
The beer in the barrel will be at an optimal position where it can be consumed without exhaustion.

In this respect, the handling of the suction member 1 is very simple, and the suction member 1 can be easily removed and attached before and after cleaning. In addition, beer suction port 1
Since it is a simple shape having A and having the seal portion 1B on the upper side, the cleaning operation itself is also simple. In order to fit the suction member 1 into the beer outlet pipe 3, for example, only a simple cylindrical shape as shown in FIG. 3 is required. The packing 1C may be fitted to the inner surface of the beer 1 so that the packing 1C fits to the outer surface of the beer outlet pipe.

On the other hand, when the beer remains in the beer barrel 10 as shown in FIG. 1, the buoyancy member 2 floats on the beer due to the presence of the float 2A and is separated from the suction member 1. Therefore, in this state, the suction member 1 and the buoyancy member 2 are completely negotiated, and there is no trouble in pushing out the beer in the barrel toward the server.

When the beer runs out, the buoyancy member 2 descends along the outer surface of the beer outlet pipe 3 as the beer runs out, and finally hits the bottom of the beer barrel 10 to close the suction port 1A of the suction member 1, as shown in FIG. State. Here, since the buoyancy member 2 has an airtight matching portion 2B with the sealing portion 1B of the suction member 1, at the same time, the sealing portion 1B and the airtight matching portion 2B
Is in contact with Further, as described above, the suction member 1 is airtightly fitted to the beer outlet pipe 3.

Accordingly, the flow path from the inside of the beer barrel 10 to the beer outlet pipe 3 is completely closed, and the generation of beer foam and the high pressure caused by the supply of high-pressure carbon dioxide to the beer outlet pipe 3 This prevents carbon dioxide from escaping.

Moreover, since the buoyancy member 2 has a simple shape having only the float 2A and the airtight matching portion 2B,
The handling is very simple, and the removal and installation before and after cleaning and the cleaning operation itself are also simple. Also, even if beer bubbles enter the beer outlet pipe 3 before the flow path is completely closed, the amount is small and the beer outlet stops at the beer outlet pipe 3 and goes to the pipeline leading to the server. There is no need for defoaming means in the pipeline. Furthermore, since the beer outlet pipe 3 is appropriately cleaned regardless of the presence or absence of beer foam, even if beer foam is contained, the work load does not increase.

The beer outlet pipe 3 and the beer barrel 10
Since beer cleaning is performed not by the beer seller but by the manufacturer, the beer foam outflow prevention device of the present invention, which is completed only in the barrel, has the advantage that hygiene quality can be controlled in the beer company.

Here, in order to make the seal portion 1B of the suction member 1 and the hermetically matching portion 2B of the buoyancy member 2 contact with high reliability, for example, as shown in FIG. 3 and FIG. And the hermetic matching portion 2B may be formed by the inner surface of the cone. Further, if the seal portion 1B and the hermetic matching portion 2B are made of an elastic material, or if the packing 1D is added to the seal portion 1B, it is more effective to improve the sealing performance. Further, in order to ensure the sealing property between the buoyancy member 2 and the bottom of the beer barrel 10, at least the lower end 2C of the buoyancy member 2 may be formed of an elastic material as shown in FIG. In particular, if the lower end 2C is formed in a conical shape, the lower end 2C is pressed against the bottom of the beer barrel 10 by the pressure of the carbon dioxide gas, which is more effective.

In order to make the buoyancy member 2 descend along the outer surface of the beer outlet pipe 3, for example, the buoyancy member 2 is simply cylindrical as shown in FIG. Just fine. In addition, the float 2A can be formed by enclosing air, but a closed foam can be used.

[0022]

As described above, according to the present invention, when the beer remains in the beer barrel, the buoyancy member floats on the beer and separates from the suction member. Since it descends along the outer surface and hits the bottom of the suction member and the beer barrel and closes the suction port of the suction member, the structure is simple, the cleaning is easy, and no bubble removing means is required.
