Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sparkling beverage dispensing cock, and more particularly, to a sparkling beverage dispensing machine for dispensing a sparkling beverage typified by beer by lever operation, and a container such as a mug. The present invention relates to an improvement of a cock which can pour finer foam into the sparkling beverage in the container after a predetermined amount of the sparkling beverage is poured out.

[0002]

2. Description of the Related Art A device for discharging a sparkling beverage by lever operation,
For example, in a beer discharging cock used for a beer server, after manually tilting a lever in one direction to pour a predetermined amount of beer into a mug, the lever is tilted in the opposite direction to cause fine bubbles of beer to flow into the mug. Some have a function to postpour into beer. A tap with a foaming function disclosed in Japanese Patent Application Laid-Open No. 9-2590 is known as a pouring cock having a function of after-foaming the foam. The reason why such fine foam is post-poured into the beer in the mug (so-called foaming) is that moderately foamed beer can pass over the throat when drinking, and this foam can quickly release carbon dioxide from beer. This is because it plays a role of preventing outflow. And in recent years,
Cream-like foams with even finer textures have been demanded as foams for later pouring.

[0003]

In the beer server having the foaming function described above, by switching a lever provided on the beer discharging cock, only the beer can be discharged from a single nozzle provided in the cock. It is to pour fine bubbles afterwards. Therefore, fine bubbles pass through the nozzle of the beer discharging cock after the beer passes, and beer passes after the fine bubble passes. However, when draft beer is dispensed by the beer server, it is important that beer and foam do not remain on the inner wall surface of the nozzle in order to impart appropriate foaming to the draft beer that has been dispensed. If beer is poured into the next mug in a state in which beer or foam remains on the inner wall of the nozzle, a lot of foam is generated and a so-called excessive foam state is easily caused. As a countermeasure, an air introduction hole is provided in the pouring nozzle so that beer and bubbles remaining on the inner wall of the nozzle fall naturally.

[0004] As described above, the foam for post-pouring is required to be creamy with a fine texture, but since the foam in this state has a high viscosity, it is also affected by air from the air inlet. Discharge of foam is time consuming and difficult. Therefore, after beer is poured out and foaming operation is performed, the operator must momentarily operate the lever to let the beer liquid flow for a moment, and then use this beer liquid to wash out the foam remaining in the cock body and nozzle. And However, since the washing operation of flowing the beer instantly requires a great deal of skill, the development of a beer pouring cock that can always dispense high-quality fine foam without such a skillful operation is awaited. Was.

[0005]

SUMMARY OF THE INVENTION The present invention has been proposed in order to preferably solve the above-mentioned drawbacks inherent in the sparkling beverage pouring cock according to the prior art. It is also an object of the present invention to provide a foamed beverage pouring cock which does not require a skilled operation of washing a nozzle or the like with a foamed beverage, and can perform appropriate foaming without becoming an excessive foaming state even for an unskilled person. .

The liquid passage of the valve stem is connected to the valve stem and communicates through a small hole formed in the other end, and the other end provided with the small hole is connected to a second valve seat provided in the slider. (2) a second valve body which is seated under the action of the elastic member, and before operation of the lever, the first valve body is seated on the first valve seat to prevent the inflow of the sparkling beverage into the sparkling beverage supply passage. At the same time, when the second valve element is seated on the second valve seat to close the small hole and the lever is operated for the first time, the valve stem is moved to the second valve seat seated on the second valve seat.
Retreating in the axial direction while opposing the first elastic member via the valve body,
Thereby, the first valve body opens the first valve seat to cause the sparkling beverage to be discharged from the sparkling beverage discharge nozzle through the sparkling beverage supply path, and the second operation of the lever causes the slider to move to the second position. 2 Advance in the axial direction against the elastic member,
Moving away from the valve stem having the first valve body seated on the valve seat,
Thereby, the second valve body opens the second valve seat to foam the sparkling beverage from the liquid passage in the pores, and transfers the obtained foam through the through-hole formed in the sleeve. It is characterized by being configured to be discharged from the discharging nozzle.

In this case, a first annular groove and a second annular groove are formed at required intervals on the outer periphery of the sleeve,

An air hole and a second air hole are drilled, and the foamed beverage dispensing nozzle communicates with the first air hole via the first annular groove only at a fixed position of the sleeve specified before operation of the lever. At the same time, the foam discharge nozzle (16) communicates with the second air hole via the second annular groove. When the lever is operated for the first time, the communication between the first annular groove and the first air hole is cut off, the introduction of external air to the beer discharging nozzle is prevented, and the second annular groove and the second air By maintaining communication with the holes, external air is subsequently introduced into the foam discharge nozzle. When the lever is operated in the second operation, the communication between the second annular groove and the second air hole is cut off, the introduction of external air into the bubble discharging nozzle is prevented, and the first annular groove and the first air The holes maintain communication and the external air is subsequently introduced into the beer discharge nozzle.

Are connected. At this time, the coil spring 40 is in a compressed state in the cylindrical hollow portion 25 of the sleeve 24, elastically urges the sleeve 24 to the right in the axial direction in FIG. 2, and moves the second valve body 42 to the second valve seat 38. I'm sitting. Note that the elasticity of the coil spring 40 is
To the left to hold the lever 18 in the upright position shown in FIG. However, the elasticity of the coil spring 40 as the second elastic member is set smaller than the elasticity of the coil spring 28 as the first elastic member.

The various valve mechanisms thus assembled are inserted into the beer supply passage 12 of the cock main body 10, and then the lever 18 is attached to the cock main body 10.
The cock body 10 is attached to the beer supply pipe 48. Since these mounting operations are known, the description of the operations is omitted. When the assembly is completed, the coil spring 28 is elastically interposed between the first valve body 30 and the conical opening surface 48a of the beer supply pipe 48. When sitting on the seat 26, the communication between the beer supply pipe 48 and the beer supply path 12 is always opened and closed.

(Operation of the Embodiment) FIG. 2 is a cross-sectional view of a beer pouring cock 44 according to an embodiment in which the various valve mechanisms shown in FIG. At this time, the lever 18 is in the neutral position before the operation, so that neither beer nor foam is poured out. That is, before the operation of the lever 18, the first valve 30 is resiliently pressed against the first valve seat 26 by the coil spring 28 disposed on the conical opening surface 48 a of the beer supply pipe 48 and is seated. The supply of beer to Road 12 is shut off. Since the second valve body 42 connected to the valve stem 34 is urged leftward in the axial direction by the coil spring 28, the second valve body 42 is seated on the first valve seat 26 provided on the slider 20, and Forty-two pores 36 are closed. Therefore, supply of beer to the beer discharging nozzle 14 and supply of foam to the foam discharging nozzle 16 are not performed.

As shown in FIG. 3, before the lever is operated, the first
The annular groove 64 and the second annular groove 66 are provided in the cock body 1.
The position is set so as to correspond to the first air hole 60 and the second air hole 62 drilled at zero. For this reason, the outside air is introduced into the first air hole 60 → the first annular groove 64 → the beer discharging nozzle 14 and the second air hole 6
2 → the second annular groove 66 → the bubble injection nozzle 16 is introduced. That is, the beer remaining on the inner wall of the beer discharging nozzle 14 by the immediately preceding beer discharging operation is easily dropped by the introduced air, and the foam discharging nozzle 1 by the immediately preceding foam discharging operation.
The bubbles remaining on the inner wall of No. 6 also easily fall by the introduced air.

(Beer Dispensing Operation) As shown in FIG. 4, when the first operation of tilting the lever 18 to the near side is performed, the slider 20 moves backward in the beer supply path 12 rightward. Since the slider 20 is connected to the sleeve 24 and the valve stem 34 connected to the end of the second valve body 42 is urged leftward by the second coil spring 40, the valve stem 34 moves rightward with the slider 20. Move in the direction. Therefore, the first valve body 30 also moves rightward against the elasticity of the first coil spring 28, and thus opens the first valve seat 26.
Thereby, the beer from the beer supply pipe 48 is discharged from the beer discharging nozzle 14 to the mug 70 shown in FIG.

At this time, as shown in the enlarged view of the main part of FIG. 5, the second valve body 42 is urged to the left in the axial direction by the coil spring 40.
Is closed. Therefore, at this stage, the foam discharge nozzle 16
There is no supply of foam to the vessel. The first of the levers 18
Since the slider 20 has been moved to the right by the operation, the first annular groove 64 of the sleeve 24 and the first
The communication with the air hole 60 has been cut off. For this reason, external air is not introduced into the beer discharge nozzle 14, and excessive foaming due to air mixing during beer discharge is effectively prevented. The position of the slider 20 in the first operation stage is determined by the position of the second annular groove 6 of the sleeve 24.
The communication between 6 and the second air hole 62 of the cock main body 10 has not been interrupted. That is, since the outside air is introduced into the foam ejection nozzle 16, the foam remaining in the nozzle 16 is continuously dropped.

As shown in FIG. 6, when the second operation of tilting the lever 18 backward is performed, the slider 20 moves the beer supply path 12 against the second coil spring 40 as shown in FIG. Move forward to the left. At this time, since the valve stem 34 is pressed leftward by the first coil spring 28 via the first valve body 30, the position of the valve stem 34 is not changed from the position shown in FIG. That is, the second valve seat 38 provided on the slider 20 is
The second valve body 42 fixed to the second valve body 42 is separated from the second valve body 42, thereby opening the small hole 36 opened in the second valve body 42. For this reason, the beer from the beer supply pipe 48 tends to flow out of the fine hole 36 through the through hole 31 penetrating the first valve body 30 and the liquid passage 32 of the valve rod 34. However, since the pores 36 are set to have a sufficiently small inner diameter in the form of an orifice as described above, the beer becomes fine foam here. As shown in FIG. 7, the foam enters the foam ejection nozzle 16 through the radial through hole 22 formed in the sleeve 24, and is later poured into the beer stored in the mug 70 from the nozzle 16. You.

At this time, as shown in the main part enlarged view of FIG. 7, the slider 20 has moved to the left by the second operation of the lever 18, so that the second annular groove 66 of the sleeve 24 and the second air of the cock body 10 The communication with the hole 62 has been cut off. Therefore, the external air is not introduced into the bubble discharging nozzle 16, and there is no possibility that air is mixed with fine fine bubbles passing through the nozzle 16 to cause bubble collapse. Note that the position of the slider 20 in the second operation stage does not interrupt the communication between the first annular groove 64 and the first air hole 60. That is, since the outside air is introduced into the beer discharging nozzle 14, the beer remaining in the nozzle 14 is continuously dropped.

[0029]

As described above, according to the sparkling beverage pouring cock according to the present invention, the foaming beverage pouring nozzle for supplying only the foaming beverage and the foam pouring nozzle for supplying only the foam are provided as separate paths. Due to the provision, even when the foamed beverage is supplied and the foam is immediately poured into the container, the foamed beverage in the container is not excessively foamed. Therefore, there is an excellent advantage that foaming of the sparkling beverage in the container can always be performed in a good condition even if the person is not an expert. Furthermore, since the external air is always introduced into each of the sparkling beverage pouring nozzles and foam pouring nozzles provided as separate paths during the standby for pouring, it is easy to drop foaming beverages and foams remaining on the nozzle inner wall. Is done. In addition, when pouring out the sparkling beverage from the sparkling beverage discharge nozzle and when pouring out the foam from the foam discharging nozzle, the introduction of external air to each corresponding nozzle is shut off, Excessive or bubble collapse is effectively prevented.
