As shown in FIG. 10, the shaft portion 120 has a diameter approximately equal to the diameter of the set hole 119.
A large-diameter portion 121 larger in diameter than the setting hole 59 is formed at the tip of the. The distal end surface of the large-diameter portion 121 is formed in a spherical shape, and the shaft portion 120 side is formed in a planar shape perpendicular to the axial direction.

Next, the operation of the first embodiment will be described.

First, the liquid container 3 is stored in the tray 35 and attached to the dispenser. As shown in FIGS. 3 and 4,
The pair of engaging holes 60 of the liquid container 3 are used as the pair of engaging portions of the tray 35.
The liquid storage bag portion 51 of the liquid container 3 is inserted into the tray 35 from above by engaging with 99, and the central area of the liquid storage bag portion 51 is connected to the tray.
It is placed on the bottom plate 75 of the 35 and the upper surface of the stepped portion 82, and both side regions are arranged along the inner side surfaces of the both side plates 76 of the tray 35. It is assumed that the extraction port portion 52 is passed under the lateral joint portion 78 and is hung from the front end portion 75a of the bottom plate 75.

Then, as shown in FIG. 11, the front door 33 of the dispenser is opened, and the tray 35 storing the liquid container 3 is opened.
Is inserted from the front into each tray mounting portion 36 of the upper space 34 and placed on the placing portion 37. When the tray 35 is placed on the placing portion 37, as shown in FIG. 1, the ribs 87, 90, 91 protruding from the lower surface of the tray 35 are placed in contact with the placing portion 37 and inclined downward to the front. The locking projections 79 projecting from the vicinity of the front ends of the both side plates 76 of the tray 35 are engaged with the stoppers 38 at the front end of the mounting portion 37 to regulate the downward inclination of the front.

At this time, the extraction port 52 of the liquid container 3 is the bottom plate.
Although it is hung from the front end portion 75a of the 75, the engaging projection 79 and the stopper 38 engage with each other at the positions of the both side plates 76 of the tray 35 which correspond to the positions of both sides of the extraction opening 52. By forming a gap portion 92 that opens forward between the front end portion 75a of the bottom plate 75, the rib portion 90a, and the placing portion 37,
The extraction port portion 52 can be prevented from being sandwiched between the tray 35 and the placing portion 37, and the tray 35 accommodating the liquid container 3 can be easily attached to the dispenser.

Then, the movable frame 112 of the quantitative extraction means 4 is opened and rotated to open the front surface of the fixed frame 111, and the extraction port portion is opened.
While the 52 is engaged with the extraction passage 113 of the fixed frame 111, the pair of setting holes 59 of the extraction opening 52 are engaged with the hooks 119 protruding from the fixed frame 111 to connect the extraction opening 52 to the extraction passage 113. To position. After that, the movable frame 112 is closed and locked on the front surface of the fixed frame 111. Since the large-diameter portion 121 is formed at the tip of the hook 119, the setting hole 59 should be formed in the large-diameter portion 12.
Even if the extraction port 52 moves toward the tip of the hook 119 by press-fitting it in 1 and passing it through the shaft 120, the setting hole 59 catches on the large-diameter portion 121, and the setting hole 59 is inadvertently inserted from the hook 119. It is possible to prevent the liquid container 3 from falling off and improve the mountability of the liquid container 3.

As a result, the extraction port portion 52 is fixed to the fixed frame body 111.
It is sandwiched between the movable frame 112 and the movable frame 112, and is arranged in the extraction passage 113. In the extraction passage 113, the quantitative extraction bag portion 55 of the extraction mouth portion 52 faces the pressing plate 116, the inlet portion 56 faces the upper pinch body 117, and the outlet portion 57 faces the lower pinch body 118. The lower end of the outlet 57 projects below the extraction passage 113. Then, the clamp 61 that closes the inlet 56 of the extraction port 52 is removed, and the tip of the outlet 57 of the extraction port 52 is cut and opened.

This completes the mounting of the liquid container 3 on the dispenser. In this embodiment, two liquid containers 3 containing different types of raw material liquids are mounted on the tray mounting portions 36 by the tray 35.

Then, as shown in FIG. 1, in the initial state where the raw material liquid is sufficiently contained in the liquid container 3, the liquid container 3 is moved forward along the inclination of the tray 35 in accordance with the weight of the raw material liquid. A force for sliding down acts, and this force overcomes the biasing force of the spring 74, and the slide body 73 moves forward.

Next, the operation of extracting the beverage by the dispenser will be described. In the standby state of the quantitative extraction means 4, the pressing plate 116 is located at the forward position where it enters the extraction passage 113,
The pressing plate 116 presses the quantitative extraction bag 55 of the extraction port 52 against the movable frame 112 to close it. Upper pinch body
117 is in the open position and the lower pinch body 118
Is in the closed position, and the lower pinch body 118 is located at the extraction port 52.
The outlet portion 57 of is closed.

In order to operate the dispenser to obtain a beverage, the cup 2 is placed on the extraction unit 1 where the beverage of the desired type is extracted, that is, on the drainboard 43 of the saucer 43. The extraction button 45 of the front door 33 corresponding to the extraction amount is pushed.

When the extraction button 45 is operated, the pressing plate 116 of the quantitative extracting means 4 of the corresponding type is retracted by the distance corresponding to the extraction amount, and the calling space 114 is formed on the front side of the pressing plate 116. To do. As a result, the quantitative extraction bag portion 55 of the extraction port portion 52 can project in the direction of the intake space 114, and the raw material liquid in the liquid storage bag portion 51 of the liquid container 3 is discharged from the extraction port portion 52 by its own weight. Quantitative extraction bag part 55 through the inlet part 56
Is called in (see Fig. 1). At this time, the amount of the raw material liquid corresponding to the amount of retreat of the pressing plate 116 is fixed to the quantitative extraction bag portion 55
Be called into.

Subsequently, the upper pinch body 117 moves to the closed position and the lower pinch body 118 moves to the open position. As a result, the upper pinch body 117 is connected to the extraction port 52.
The inlet 56 is closed to prevent the raw material liquid in the liquid storage bag 51 from flowing into the extraction port 52. Lower pinch body 118
By moving to the open position, the outlet of the extraction port 52
57 is opened, and the raw material liquid drawn into the quantitative extraction bag portion 55 is extracted from the lower end of the outlet portion 57 into the cup 2 or the mixing ball 41 arranged in the extraction portion 1. Further, the pressing plate 116 moves forward to move the quantitative extraction bag portion 55 to the movable frame 112.
By forcibly pressing against, the raw material liquid in the quantitative extraction bag portion 55 is forcibly extracted.

Subsequently, after a lapse of a predetermined time in consideration of the time when the sagging of the raw material liquid from the outlet part 57 of the extraction port part 52 is eliminated, the upper pinch body 117 is moved to the open position and the lower pinch body 118 is moved. To the closed position. As a result, the quantitative extraction means 4 returns to the initial standby state, a series of extraction operations of the raw material liquid are completed, and the next raw material liquid extraction operation waits.

On the other hand, in response to the extraction operation of the raw material liquid, the cold water supply device 5 operates to extract cold water into the cup 2 or the mixing ball 41 of the extraction section 1 and then into the cup 2 or the mixing ball 41. The raw material liquid and cold water are mixed with each other to prepare a diluted beverage. When the mixing ball 41 is used, the beverage mixed and diluted with the mixing ball 41 is extracted into the cup 2.

Then, as shown in FIG. 2, when the extraction of the raw material liquid from the liquid container 3 is repeated and the remaining amount of the raw material liquid in the liquid container 3 decreases, the raw material liquid is sufficiently contained. The weight becomes lighter than that at the initial stage, and the biasing force of the spring 74 is greater than the force of the liquid container 3 sliding down forward along the inclination of the tray 35 in accordance with the weight of the raw material liquid, and the slide body 73 moves. Move backwards.

Therefore, regardless of the amount of the raw material liquid in the liquid container 3, the liquid storage bag portion 51 of the liquid container 3 is always tensioned, so that the remaining amount of the raw material liquid in the liquid container 3 decreases. During the extraction of the raw material liquid, a certain amount of the raw material liquid is drawn into the extraction opening portion 52 within a constant time from when the pressing plate 116 retracts to when the upper pinch body 117 closes the inlet portion 56 of the extraction opening portion 52. Therefore, it is possible to prevent the quantitativeness of the raw material liquid from decreasing in a decreasing direction.

Further, when the remaining amount of the raw material liquid in the liquid container 3 decreases, the liquid storage bag portion 51 of the liquid container 3 becomes wrinkled,
A phenomenon in which the raw material liquid remains in the wrinkled portion occurs, but the rear end of the liquid storage bag portion 51 of the liquid container 3 is attached to the spring 74.
The liquid storage bag portion 51 can be stretched by pulling it back by the urging of the liquid storage bag portion 51 to extend the wrinkles that are likely to occur in the liquid storage bag portion 51, so that the remaining amount of the raw material liquid at the time when quantitative extraction cannot be performed. Can be reduced. Therefore, even if the raw material liquid in the liquid storage bag portion 51 of the liquid container 3 decreases, the liquid storage bag portion
A fixed amount of the raw material liquid can be drawn into the extraction port portion 52 from inside 51, the waste of the raw material liquid can be reduced, and the replacement time of the liquid container 3 can be extended.

As described above, the front end portion of the bottom plate 75 of the tray 35 is
