The shape produced in the state curved to the outside is also applicable.

That is, rubber or silicone having elastic force is easily stretched in the direction of increasing length, but compression is not easy in the direction of decreasing length. Therefore, since the intermediate portion 420 is formed as a continuum along the circumference, the intermediate portion 420 is bent while being extended outward when the force is received from the upper portion as the plunger 30 descends. In this case, when the plunger 30 is raised, the intermediate portion 420 has an elastic force in an upward direction and is restored to its original straight shape.

Act on the sheet 314. As a result, the air between the first valve 200 and the second valve 300 is discharged through the second flow hole 312 while the valve seat 314 is sagging downward. The pressure is lowered between the valve 200 and the second valve 300.

In this state, when the electric supply of the solenoid coil 20 is cut off, the plunger 30 and the first valve 200 are raised by the elastic force of the elastic body 400. At this time, the lower pressure of the first valve 200 is formed lower than the upper pressure, and the first valve seat which is in contact with the lower side of the first through hole 222 of the first cylindrical plate 220 by such a pressure difference. The portion 214 is formed to sag down to form a flow path, the first beverage 200 is filled in the beverage source liquid filled in the first valve 200 through the first through hole (222) and the first flow hole (212) And flows into the space between the second valve 300.

When the beverage feed liquid introduced into the space between the first valve 200 and the second valve 300 is supplied with electricity to the solenoid coil 20 again and the plunger 30 is lowered, the first valve 200 ) And the pressure between the second valve 300 is increased so that the second valve seat 314 sags downward to the outlet 120 through the second through hole 322 and the second flow hole 312. Discharged.

As the above process is repeated, the user can adjust the amount of the beverage stock solution mixed with cold water or hot water to a desired concentration.

As described above in detail, according to the present invention, the beverage stock solution discharging control device in the pouch provided with the elastic body and the leakage preventing structure has a straight shape so that the middle part of the elastic body can be tensioned in the outward direction. This does not occur, and the restoring force is improved when the plunger rises, and thus the smooth beverage solution can be discharged. In addition, by forming a leak-proof structure on the first valve and the first cylindrical plate, the second valve and the second cylindrical plate so that the beverage solution on the upper portion of the first cylindrical plate and the second cylindrical plate leaks downward through the flow hole. There is an effect that can be prevented.
