Further, when the gas supply member 3 is attached to the pouring member 1, the gas supply member 3 can be attached very easily by simply sliding the gas supply member 3. Hereinafter, each of the above members will be described in detail. As shown in FIGS. 1, 4 and 5, a discharging member 1 includes a discharging valve 2 for discharging a liquid, and a receiving portion which is fitted to a gas supply port 4 of a gas supply member 3 and receives gas. And a locking portion 6 formed near the receiving portion 5 and to which the gas supply member 3 is detachably attached. Reference numeral 7 denotes a main body of the pouring member 1. A large hole 8 is formed in the main body 7 from above (FIGS. 5 and 5 are enlarged views of FIG. 4). Below the large hole 8, a tapered portion 10 whose diameter is reduced to a taper 9 is formed.
Are formed integrally with the large hole 8. Below the tapered portion 10, a small-diameter portion 11 having a smaller diameter is formed continuously with the tapered portion 10.
Communicates with the cavity 14 below the main body 7 through the second tapered portion 12 and the hole 13. Reference numeral 15 denotes a valve stem which is inserted into the large hole 8 so as to be movable up and down in the figure. The valve stem 15 has a first seal portion 16 which slides inside the large hole 8 halfway. And this seal part 1
6 and a drum part 17 formed continuously below the
7, a second seal portion 18 abutting on the tapered portion 10, and a second seal portion 18 slidably provided in the small diameter portion 11.
A third seal portion 19 which is continuous with the seal portion 18 is formed. In addition, reference numerals 20 to 22 are sealing parts. A screw 23 is attached to one end of the valve stem 15, and the screw 23 is attached to the second seal portion 18.

The seal 22 constituting the third seal portion 19 is sandwiched between the screw 23 and one surface of the trapezoidal part 24. Reference numeral 25 denotes a bottomed hole formed in the screw 23, and reference numeral 26 denotes an opening at one end in the peripheral wall of the trapezoidal part 24 and the other end at the bottom 25a of the hole 25.
Is a small hole that is provided in the opening. Reference numeral 27 denotes a cap provided by being screwed on the upper portion of the main body 7, and a spring 28 is provided inside the cap 27.
Always urges the valve stem 15 downward in the drawing, that is, the respective seal portions are closed. Further, the other end of the valve stem 15 projects upward from the main body 7 in the figure to form an operating end 29. The operating end 29 is provided with a lower end 30a of a lever 30 for operating the valve stem 15. Installed. And this lever 3
It is possible to switch between liquid beer and foam by tilting 0 toward the front in the figure or by tilting it to the back side in the drawing. More specifically, when the valve stem 15 largely moves upward during the upward stroke of the valve stem 15, the third seal portion 19 and the second seal portion 18 are each moved to the small-diameter portion 1.
1, the liquid, for example, beer, which separates from the tapered portion 10 and passes through the hole 13, passes through the small-diameter portion 11 and the tapered portion 10,
7 and is discharged out of the main body 7 through a discharge port 7a formed on the side surface of the drum portion 17 in FIGS. A nozzle 7b is attached to the discharge port 7a as shown in FIG. In the upward stroke of the valve stem 15,
When the valve stem 15 moves upward slightly, the third seal portion 19 does not separate from the small diameter portion 11. However, since the second seal portion 18 is separated from the tapered portion 10, the liquid, for example, beer from the hole 13 is prevented from flowing out of the third seal portion 19, and reaches the hole 25 formed in the screw 23. , Bottom 2
It flows into the small hole 26 through 5a. The beer that has flowed into the small hole 26 is removed from the tapered portion 1 where the second seal portion 18 is separated and a passage is formed.
It is discharged from 0 to the outside of the main body 7 through the discharge port 7a through the drum portion 17. The diameter of the hole 25 differs from that of the small hole 26 as shown in the figure, and the diameter of the hole 25 is larger than that of the small hole 26. As a result, the liquid flows from the hole 25 to the small hole 26.
, The carbonic acid in the beer foams and becomes fine bubbles due to the pressure change or the like, so that when the valve rod 15 moves up small, the fine bubbles flow out from the discharge port. That is, when beer is supplied (poured) to an external glass or the like, the valve stem 15 is initially set.
The liquid (beer) is poured by increasing the upward stroke, and when the liquid reaches the desired amount in the glass, the upward stroke of the valve rod 15 is decreased to supply foam onto the beer in the glass ( pour it up). Reference numeral 31 denotes a seal, and a cylindrical skirt portion 32 is formed below the main body 7.
Is provided on the upper ceiling 7 c in the hakama part 32, and the space 14 is formed in the hakama part 32. And code 3

The other end of 4 will be immersed in the beer inside the beer can 100. In FIG. 4, a member screwed on the screw 35 of the skirt portion 32 is an adapter 36.
Is a can of beer such as the 2 liter can or 3 liter can
It is used because the size of 00 is different for each manufacturer. Therefore, the adapter 36 has a lower end 37 formed at the lower end in the same manner as described above, and a threaded portion is formed on the inner wall so that the lower end 37 can be attached to a beer can 100 such as a 2 liter can or 3 liter can of another manufacturer. 38 is screwed. The seal 39 is attached to the partition wall 41 having the hole 40 in the same manner as described above so that the inside of the beer can 100 is isolated from the outside when the adapter 36 is attached to the beer can. When the beer can 100 of another maker is set, the outside is shut off by the seal 39 in the same manner as described above. A hole 42 is formed in the main body 7 so as to open into the space 14, and this hole 42 is a continuous small hole 43.
And the small hole 43 communicates with the gas supply port 4. Therefore, the carbon dioxide gas from the gas supply port 4 reaches the cavity 14 through the small holes 43 and 42 and exerts a pressure on the liquid level of the beer can 100 opened in the cavity 14. As a result, when the lever 30 is actuated to move the valve stem 15 upward, the pressurized beer is supplied to the outside through the tube 34 and the second tapered portion 12. Next, the structure of the gas supply member 3 will be described with reference to FIGS.
This will be described with reference to FIG. Reference numeral 44 denotes a main body of the gas supply member 3. The main body 44 is roughly divided into a locking portion 6, a pressure reducing mechanism 45, and a cylinder storage portion 46. Incidentally, the locking portion 6 (male side) engages with the mounting portion (female side, which will be described later) of the main body 7 to connect the spouting member 1 and the gas supply member 3. The configuration is such that a locking portion 6 is provided on the member 3 side. Of course,
It goes without saying that the locking portion 6 may be on the side of the pouring member 1 and the mounting portion (described later) may be on the side of the gas supply member 3. The locking portion 6 is mounted below the main body 44 in the figure, and the main body 44 is mounted above the locking portion 6 at an angle. The depressurizing mechanism 45 on the left side of the main body 44 in FIG. 3 is a known depressurizing mechanism, and the details thereof are omitted. This is supplied to the small holes 43 in FIGS. The cylinder housing 46 is provided with a screw 48 on the main body 44.

The screw member 50 on which the screw 48 is formed is made of metal, and is formed so as to be integrated with the main body 44 when the main body 44 is molded with resin. The screw member 50 is hollow, and a seal 52 is attached to the inner upper end 51a. And the open end 47b of the cylinder 47 is
The cylinder case 49 is constantly pressed against the seal 52 by being screwed to the screw 48. 53
Is a hollow pin attached to the main body 44. The hollow pin 53 has a hollow passage formed therein. The hollow pin 53 penetrates through a plate (not shown) attached to the open end 47 b of the cylinder 47 and enters the interior of the cylinder 47. That is, when the cylinder 47 is displaced in the direction of the seal 52, the hollow pin 53 is moved to the cylinder 47. And the carbon dioxide gas inside the cylinder 47 flows into the hollow passage of the hollow pin 53. The hollow pin 53 is connected to the pressure reducing mechanism 45 as described above, and the high-pressure carbon dioxide gas in the cylinder 47 is removed by the pressure reducing mechanism 45.
At this time, a predetermined low-pressure carbon dioxide gas is supplied to the small holes 43 in FIGS. Reference numeral 54a denotes a hole as a first safety mechanism provided so as to penetrate the screw member 50.
The hole 54a connects the outside with the inside of the cylinder case 49, and carbon dioxide gas blows out from the hole 54a when used incorrectly.
That is, during normal use, the carbon dioxide gas in the cylinder 47 is sent to the pressure reducing mechanism 45 through the hollow pin 53, and the cylinder 47 is replaced when the cylinder 47 becomes empty. However, it is mistaken that the cylinder 47 is empty. And try to remove the cylinder case 49. Then, the cylinder case 49 is vigorously detached from the screw 48 by the residual gas in the cylinder 47. In order to prevent this from happening, the cylinder 47
At the moment when the open end 47b of the
Residual gas is ejected from 4a, and serves to reduce the pressure inside the cylinder case 49. The lower end 49a of the cylinder case 49 is also provided with a hole 54b for communicating the inside of the cylinder case 49 with the outside of the cylinder case 49. The hole 54b prevents the cylinder case 49 from coming off from the screw 48 by vibrating the carbon dioxide gas from the hole 54b when the residual gas cannot be exhausted by the hole 54a alone. Reference numeral 45a denotes a stopper of the pressure reducing mechanism 45,
Turns the gas on and off by rotating the head until it hits the stopper 45a. Next, the locking portion 6 and the mounting portion 55 will be described.
