DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a beer cock used when pouring beer into a container such as a mug, and more particularly to an improvement in a beer cock having a function of putting foam on the poured beer.

[0002]

2. Description of the Related Art Conventionally, a beer cock for discharging beer into a container such as a mug is provided with a function of foaming and discharging beer after pouring beer, and placing foam on the poured beer. I have. 10 to 12 show the structure of a conventional beer cock having a foaming function. 10 shows a non-poured state, FIG. 11 shows a beer pour-out state, and FIG. 12 shows a foam pour-out state.

[0003] The beer cock has a tubular body 1, a movable rod 2 movably mounted on the axis of the tubular body 1, and a valve mounted on the movable rod 2 for opening and closing a hollow hole 1 A of the tubular body 1. 3, an operation lever 4 for pushing the movable rod 2 inside the hollow hole of the tube 1, and a beer spout 5 branched from the hollow hole of the tube 1. A beer supply pipe 10 is connected to the hollow hole of the tube 1, and beer pressurized to, for example, about ² to 3 kg / cm ² is supplied through the beer supply pipe 10.

The valve 3 is pressed against a narrow portion 1B formed in the hollow hole 1A of the tube 1 to keep the hollow hole 1A of the tube 1 closed. When the operation lever 4 is tilted in the counterclockwise direction, the movable rod 2 moves rightward, the valve 3 separates from the narrow portion 1B, and switches from the closed state shown in FIG. 10 to the open state shown in FIG. Therefore, in the state shown in FIG. 11, beer can be poured from the beer outlet.

[0005] When the pouring of the beer is completed, the state returns to the state shown in Fig. 10 again, and thereafter the operating lever 4 is tilted clockwise. When the operation lever 4 is tilted clockwise, the movable rod 2 moves to the left as shown in FIG. At this time, since the valve 3 is kept in contact with the narrow portion 1B, the movable rod 2 moves by compressively deforming the spring 3A. As a result, the valve 3 is
The small-diameter hole 2B formed in the movable rod 2 is exposed away from the flange portion 2A formed in the movable rod 2. Since the small-diameter hole 2B communicates with the hollow hole 2C formed along the axis of the movable rod 2, beer is injected into the hollow hole 2C from the small-diameter hole 2B into the hollow hole 1A through the movable rod 2 and foamed. The foam is poured from the beer outlet 5. Put this foam on top of beer for drinking.

[0006]

The conventional beer cock uses a common beer outlet 5 for beer pouring and foam pouring. For this reason, if the next beer pouring operation is performed immediately after the foam is poured, a phenomenon occurs in which the foam remaining and attached to the beer pouring port 5 is poured into the container together with the next beer. As a result, when beer pouring is continuously performed, there is a disadvantage that the amount of foam increases and the amount of beer substantially decreases.

In order to solve this drawback, a hole 1C communicating with the hollow body 1A of the tube 1 and the outside air is provided between the tube 1 and the hollow hole 1A of the tube 1 and the beer outlet 5. A communicating hole 1D is provided, and these holes IC and 1D are communicated in a non-poured state (FIG. 10) to communicate the upper part of the beer outlet 5 with the atmosphere, and the bubbles remaining in the beer outlet 5 are dropped. There is also a structure for causing the bubbles to be removed, but even if this structure is used, it takes time to completely remove the bubbles, and there is an inconvenience when pouring out continuously.

[0008] An object of the present invention is to propose a beer cock having a structure in which the foam poured out last time does not mix with the beer to be poured out next time.

[0009]

The present invention is characterized by a structure in which a beer outlet and a foam outlet are separated, and beer and foam are separately discharged. Therefore, according to the present invention, since the spouts provided separately for beer pouring and foam pouring are used, the foam poured last time does not mix with the beer to be poured next time. Therefore, even if beer and foam are continuously poured out, an advantage that the amount of foam, that is, the amount of beer can be kept constant can be obtained.

Further, the present invention proposes a structure in which a beer outlet and a foam outlet are provided close to each other. By adopting this structure, there is obtained an advantage that beer injection and foam injection can be performed continuously without significantly moving a container such as a mug. Further, the present invention proposes a structure in which a hollow hole is formed in the first opening / closing valve for beer discharging, and a second opening / closing valve for discharging foam is mounted inside the hollow hole. It also proposes a structure in which the on-off valve and the second on-off valve are opened and closed by a common operation lever, and a structure in which the first on-off valve is opened and closed by an operation lever and the second on-off valve is opened and closed by a push button. .

[0011] According to the structure of the beer cock according to the present invention, the beer pouring operation and the foam pouring operation can be performed by the common operation lever, even though the beer pouring port and the foam pouring port are separately provided. Can do it. Therefore, a beer cock with good operability can be provided. In addition, in the case where the foam is poured by the push button, the operability of the push button can be improved by setting a weak biasing force of the spring for returning the push button. Therefore, there is an advantage that a beer cock with good operability can be provided regardless of the structure.

[0018]

As described above, according to the present invention, the beer outlet 5 and the foam outlet 6 are provided separately.
There is no possibility that the foam previously poured out is poured into the container together with the beer at the next beer pouring. Therefore, there is an advantage that the tendency that the amount of foam is increased even when beer is continuously poured out can be eliminated.

Further, since the beer outlet 5 and the foam outlet 6 are provided as close as possible, it is possible to continuously inject beer and foam without moving the container for receiving beer. The advantages that can be obtained are also obtained. In addition, in the case where the operation lever 4 is configured to be able to perform both beer pouring and foam pouring, both operations can be performed while the operating lever 4 is being held, so that operability is good.

Further, even in the case of employing a structure in which bubbles are poured out by the push button 30, the pressing force of the push button 30 can be reduced by setting the biasing force of the spring 23 to be relatively weak. In this respect, a beer cock with good operability can be provided.
