  In the flexible valve body 222, as shown in FIG. 3A, the movable seal portions 222a and 222b are usually spaced apart from the liquid discharge pipe 23 and the upstream ends 23a and 24a of the bubble discharge pipe 24, respectively. As shown in FIG. 3B, when the movable seal portion 222a or 222b is pressed by the valve rod 223 or 224, the movable seal portion 222a or 222b injects liquid while extending the flexible film portion 222c or 222d. The upstream end 23 a of the outlet pipe 23 or the upstream end 24 a of the bubble pouring pipe 24 is closed. On the other hand, the valve rods 223 and 224 can be configured to be movable substantially horizontally in a guide hole 225a provided in a guide member 225 which is detachably fixed to the valve case 221, for example.

  The upper part 13 of the body 1 shown in FIG. 1 is formed by connecting claws 131 provided at a plurality of locations on the lower periphery of the body 1 and coupled portions (not shown) provided at a plurality of locations on the outer periphery of the upper bottom portion 121 of the intermediate cylinder 12. And the upper bottom portion 121 of the intermediate cylinder 12 so as to be separably connectable, and are a power source for driving the air pump 3, the ultrasonic transducer 4, and the air pump 3 and the ultrasonic transducer 4 inside. The battery (for example, two AA batteries) 5 or a circuit board (not shown) and a lever 61 protruding outward from the upper surface of the upper part 13 can be pivoted within a predetermined angle range around the rotation shaft 62 by pivoting operation The cam 6, and a pair of cam rods 63 and 64 disposed at the lower side of the cam 6 so as to be capable of reciprocating in the vertical direction and whose lower end can contact the valve rods 223 and 224 in the valve device 22, and the cam rods 63 and 64 The respective rod 22 , A pair of springs 65 and 66 resiliently biased mounted to the direction (upward) to separate from the 224.

  The cam 6 is formed with a pair of projections 6a and 6b that can contact the upper ends of the cam rods 63 and 64 by rotation at mutually different angles in the circumferential direction, and the projections 6a and 6b are cams by the rotation of the cam 6. The rods 63, 64 are selectively pushed down against the biasing force of the springs 65, 66. Further, sloped surfaces 63a and 64a are formed at the lower ends of the cam rods 63 and 64, and the slopes 63a and 64a are sloped surfaces 223a formed at the rear ends of the valve rods 223 and 224 in the process of pressing down by the cam 6. The valve rods 223 and 224 can be slid in the horizontal direction to selectively open and close the movable seal portions 222a and 222b of the flexible valve body 222.

  The air pump 3 supplies air into the pressurizing chamber 10 of the body 1, and the liquid level of the beer in the beer can 100 via the spout opened on the upper surface of the beer can 100 stored in the pressurizing chamber 10 The air pressure supply path extending from the discharge port of the air pump 3 is opened to the pressure chamber 10 from the upper bottom portion 121 of the intermediate cylinder 12 of the body 1.

  The ultrasonic vibrator 4 is formed of, for example, a piezoelectric element, and is disposed in a state of being in contact with the foam pouring pipe 24. Ultrasonic vibration is generated by applying a high frequency voltage by an oscillation circuit (not shown). The generated ultrasonic vibration is transmitted to the bubble pouring pipe 24.

  Further, a switch (not shown) is attached to the cam 6. Then, the cam 6 is rotated in the pushing direction of the cam rod 64 by the swing operation of the lever 61, that is, in the counterclockwise direction in FIG. 2, and is pushed through the valve rod 224 as shown in FIG. , The movable seal portion 222b of the flexible valve body 222 closes the upstream end 24a of the bubble pouring pipe 24, and the movable seal portion 222a of the flexible valve body 222 opens the upstream end 23a of the liquid pouring pipe 23 Then, the electric power from the battery 5 is supplied to the drive circuit of the air pump 3 through the switch of the cam 6, and conversely, the cam 61 is pushed down by the swing operation of the lever 61, ie, clockwise in FIG. The movable seal portion 222a of the flexible valve body 222, which is rotated via the valve rod 223 as shown in FIG. When the movable seal portion 222b of the flexible valve body 222 opens the upstream end 24a of the bubble pouring pipe 24 while closing the valve 23a, the power from the battery 5 is supplied to the drive circuit of the air pump 3 via the switch of the cam 6 And to the oscillation circuit of the ultrasonic transducer 4.

  Next, a procedure for pouring a canned beer into a beer glass or the like using the beverage server having the above configuration will be described.

  First, the lower part 11 of the body 1 and the intermediate cylinder 12 are separated from each other, and the beer can 100 of canned beer such as 350 mL or 500 mL can be appropriately cooled, and the outlet is opened by the pull tab on the upper surface Then, the beer can 100 is placed on the bottom surface of the cylindrical portion 112 in the lower part 11 of the body 1.

  Here, since the upstream side pouring pipe 21 in the pouring unit 2 extends in the inner peripheral space of the intermediate cylindrical body 12 to which the upper part 13 is joined, the upstream side pouring pipe 21 is used as a beer can 100. The intermediate cylindrical body 12 is put on the cylindrical portion 112 of the lower part 11 while inserting the beer can 100 into the beer can 100 from the spout opening at the upper surface of the joint, and the coupling provided on the lower outer periphery of the intermediate cylindrical body 12 The intermediate tubular body 12 and the tubular portion 112 of the lower part 11 are coupled to each other by a not-shown coupled portion provided on the outer periphery of the upper end of the tubular portion 112 in the claw 122 and the lower part 11. And by doing in this way, the pressure chamber 10 sealed between the cylinder part 112 of the lower part 11 and the intermediate cylinder 12 is defined, and the state where the beer can 100 was accommodated in this pressure chamber 10 It becomes.

  Then, after an appropriate beer glass is placed on the tray portion 113 of the lower part 11 of the body 1, when the lever 61 is tilted to the left in FIG. 1, for example, the cam 6 is rotated counterclockwise in FIG. The cam rod 64 is pushed down against the biasing force of the spring 66 by the projection 6b of the cam 6, and the slope 64a at the lower end thereof slides on the slope 224a formed at the rear end of the valve stem 224 horizontally. Because the valve device 22 is pressed from the neutral state shown in FIG. 4, as shown in FIG. 5, one movable seal portion 222b of the flexible valve body 222 is stretched and deformed by the valve stem 224. And closely contact the upstream end 24 a of the bubble pouring pipe 24 to close the bubble pouring pipe 24. On the other hand, since the projection 6a of the cam 6 does not push down the cam rod 63, the movable seal portion 222a of the flexible valve body 222 does not advance and the liquid discharge pipe 23 is in an open state.

  At this time, since the power from the battery 5 is supplied to the drive circuit of the air pump 3 via the switch of the cam 6, air is sent to the pressurizing chamber 10 by the driving of the air pump 3, and the pressurizing chamber 10 is pressurized. Be pressed. For this reason, the air pressure of the pressure chamber 10 acts on the liquid surface of the beer in the beer can 100 stored in the pressure chamber 10 through the spout opened on the upper surface of the beer can 100, and the pressure of the external atmosphere The beer in the beer can 100 is poured from the upstream side pouring pipe 21 of the pouring unit 2 through the liquid pouring pipe 23 in the valve case 221 and in the open state, The beer is poured from the outlet nozzle 25 a onto the beer glass on the tray portion 113.

  Then, when an appropriate amount of beer is poured into the beer glass, when the lever 61 is tilted to the opposite side (for example, the right side in FIG. 1), the cam 6 is rotated clockwise in FIG. The cam rod 63 is pushed down against the biasing force of the spring 65 by the projection 6a, and the sloped surface 63a at the lower end of the cam rod 63 slides horizontally with the sloped surface 223a formed at the rear end of the valve rod 223 At the same time, the other cam rod 64 is lifted by the biasing force of the spring 66. Therefore, in the valve device 22, the movable seal portion 222 a of the flexible valve body 222 is advanced by the valve rod 223 from the state shown in FIG. 5 with extension and deformation of the flexible membrane portion 222 c. The movable seal portion 222b closely contacts the upstream end 23a and closes the liquid injection pipe 23, while the movable seal portion 222b retracts the valve rod 224 by the elastic contraction force of the flexible membrane portion 222d, and the upstream end of the foam injection pipe 24 At a distance from 24a, the bubble pouring pipe 24 is opened.

  At this time, since the power from the battery 5 is supplied to the drive circuit for driving the air pump 3 and the oscillation circuit for driving the ultrasonic vibrator 4 through the switch of the cam 6, the pressurizing chamber is driven by the drive of the air pump 3. While air is sent to the pressure chamber 10 and the pressure chamber 10 is pressurized, the ultrasonic transducer 4 generates ultrasonic vibration by the high frequency voltage to excite the bubble pouring pipe 24. For this reason, when the beer in the beer can 100 passes the foam pouring pipe 24 from the upstream pouring pipe 21 in the pouring unit 2 through the foam pouring pipe 24 in the valve case 221 and in the open state. By receiving ultrasonic vibration, fine creamy bubbles are formed, and the bubbles are poured from the bubble pouring nozzle 25 b of the nozzle member 25 to the beer glass on the tray portion 113.

  Then, when the required foam is poured out, when the lever 61 is returned to the substantially vertical position, the switch of the cam 6 shuts off the drive circuit of the air pump 3 and the oscillation circuit of the ultrasonic transducer 4. The driving of the vibrator 4 is stopped and the pouring is finished.

  That is, according to the illustrated form of the beverage server, after pouring an appropriate amount of beer into a beer glass, the fine foam is poured on it to form a creamy foam layer, so that the mouthfeel of the drink is good. At the same time, it suppresses the release of carbon dioxide from the beer, so that the taste can be improved. Moreover, since the upstream end (lower end) of the upstream side pouring pipe 21 in the pouring unit 2 has a length reaching the bottom surface of the beer can 100 stored in the pressure chamber 10, almost no beer is left inside Can be poured out.

  Then, after washing, when washing the wetted part in the pouring unit 2 in order to prevent the generation of bacteria and mold, first, by opening the connecting claw 131 provided on the upper part 13 of the body 1 When the upper part 13 is removed from the upper bottom portion 121 of the cylindrical body 12, the pouring unit 2 can be separated and removed from the upper bottom portion 121 of the intermediate cylindrical body 12 from the body 1. Therefore, as shown in FIG. 7, the flexible valve body 222 is removed by removing the flexible valve body 222 made of a rubber elastic material such as silicone rubber from the opening edge of the valve case 221 of the valve device 22 in the pouring unit 2. The cleaning of the inside of the valve case 221, the inside of the upstream side pouring pipe 21, the inside of the liquid pouring pipe 23, and the inside of the bubble pouring pipe 24 can be easily performed.

  After washing, after draining, the flexible valve body 222 is fitted to the valve case 221, and then the upstream side pouring pipe 21 is attached to the mounting hole 121a formed in the upper bottom portion 121 of the intermediate cylindrical body 12 of the body 1. The valve device 22 and the nozzle member 25 are fitted into the upper bottom portion 121 of the intermediate cylinder 12, and then the upper part 13 is covered on the intermediate cylinder 12 and coupled by the coupling claws 131. It can be easily assembled.

  Next, FIG. 8 shows a valve device in another preferred embodiment of the beverage server according to the present invention. In this embodiment, the difference from the above-described embodiment is that the movable seal portions 222a and 222b of the flexible valve body 222 are selectively pressed and the upstream end 23a of the liquid discharge pipe 23 or the bubble discharge The valve rods 223 and 224 closely contacting or separating from the upstream end 24 a of the pipe 24 double as the cam rods 63 and 64 shown in FIGS. 1 to 3.

  Specifically, the upstream ends 23 a and 24 a of the liquid injection pipe 23 and the foam injection pipe 24 are open upward in the valve case 221, and the outer peripheral portion is in close contact with the upper opening 221 a of the valve case 221 detachably. In the flexible valve body 222, the movable seal portions 222a and 222b are located above the upstream ends 23a and 24a of the liquid injection pipe 23 and the foam injection pipe 24, respectively. In addition, the flexible film portions 222 c and 222 d of the flexible valve body 222 are formed in a bellows shape.

  Then, by the rotation of the cam 6 shown in FIG. 2, the projections 6a and 6b formed on the cam 6 selectively push down the valve rods 223 and 224 against the biasing force of the springs 65 and 66, and the valve rods As shown in FIG. 8B, the movable seal portions 222a and 222b of the flexible valve body 222 are deformed as shown in FIG. 8B by deformation of the flexible membrane portions 222c and 222d. And selectively block the upstream ends 23a and 24a of the liquid injection pipe 23 and the foam injection pipe 24.

  Therefore, according to this embodiment, since the valve rods 223 and 224 double as the cam rods 63 and 64 shown in FIGS. 1 to 3, the number of parts can be reduced and the structure can be simplified.

  Further, also in this embodiment, as shown in FIG. 9, the injection unit 2 including the upstream side injection pipe 21, the valve device 22, the liquid injection pipe 23, the foam injection pipe 24 and the like is removed from the body. By removing the flexible valve body 222 from the upper opening of the valve case 221 of the device 22, the flexible valve body 222 is cleaned, the inside of the valve case 221, the inside of the upstream side pouring pipe 21, the liquid pouring pipe 23 and The inside of the bubble pouring pipe 24 can be easily cleaned.

  In the embodiment described above, the pressing chamber 10 closely covers the intermediate cylindrical body 12 on the cylindrical portion 112 of the lower part 11 of the body 1 so that the coupling claw 122 and the lower portion provided on the intermediate cylindrical body 12 Although it is defined by joining by the to-be-joined part provided in part 11, it is possible to be connected by screwing type, and cylinder part 112 of middle cylinder 12 and lower part 11 may be used, or A door may be connected openably and closably to each other via a hinge, and a door which can be opened and closed is provided on the body 1, and the container-containing beverage is taken in and out from this door, and the pressure chamber 10 is sealed by the door. Things are also conceivable.

  Moreover, if it is a container of the magnitude | size which can be stored not only in canned beer, such as 350 mL or 500 mL, but the pressurization chamber 10, a bottle, a PET bottle, etc. will be received by the application of the air pressure in the pressurization chamber 10. Beverages can be dispensed from any container. Needless to say, the beverage is not limited to beer.

  Further, in all the illustrated embodiments, a plurality of downstream side pouring pipes (the liquid pouring pipe 23 and the foam pouring pipe 24) are provided, and the valve device 22 is constructed of beer from the upstream side pouring pipe 21. Since the flow path is switched to the liquid injection pipe 23 or the foam injection pipe 24, the movable seal portions 222 a and 222 b of the flexible valve body 222 are the upstream ends 23 a of the liquid injection pipe 23 and the foam injection pipe 24, If it is intended to be in close contact with or separated from 24a, but the valve device 22 is to open or shut off between the upstream outlet pipe 21 and a single downstream outlet pipe, the flexible valve body 222 may open and close the downstream end 21a of the upstream side pouring pipe 21.
