The beverage is held in a flexible bag, and the beverage is taken out and supplied using its own weight or a pump. Since this flexible bag is made of a material such as transparent polyethylene, it is possible to visually see if the liquid runs out. To check, the box had to be opened each time, which was extremely troublesome.

袋は好ましくない。(c) Problems that the invention aims to solve For this reason, there is a method of detecting liquid shortage using a pressure switch that operates with negative pressure when the interior of a flexible bag contracts due to lack of beverage; Since the shape of the body is not constant, detection accuracy becomes unstable.
Therefore, the most certain one is, for example, Jikko 54-
As shown in Japanese Patent No. 2687, this is a detection method based on the resistance between a pair of electrodes. However, attaching electrodes while maintaining airtightness increases the cost of the bag. The biggest advantage of this kind of beverage dispenser is that it prevents the beverage from coming into contact with the outside air until it is supplied outside, and considering the current situation where bags are disposable, such expensive bags are not recommended. is not desirable.

防止している。(F) Embodiment Figure 1 shows the structure of a beverage dispenser, in which a beverage outlet pipe 5 is formed at one end, and the beverage is then filled with a thin plastic material such as a thin synthetic resin that shrinks as the beverage is discharged. The bag is made of a flexible material, and the tip of the beverage outlet tube 5 is usually sealed. Reference numeral 6 denotes a box body for storing the bag 1 filled with beverage and protecting it from external impact, and a take-out port 7 for taking out the beverage outlet pipe 5 of the bag 1 is formed in a part thereof. 3 is a beverage detection device, in which a small chamber 9 equipped with a pair of electrodes 8 is connected to a conduit 10.
is formed. Reference numeral 2 uses a pump to draw out a fixed amount of the beverage in the bag 1 and pour it into a cup 11. 4 is conduit 10
This check valve is attached to a valve and has an outside air introduction hole 11. As shown in FIG. The valve body 16 prevents the beverage from flowing out of the conduit 10.

スを注入して供給する装置には好適である。 With the above configuration, the box body 6 and the bag 1 are connected to the pump 2 by cutting the outlet pipe 5 and inserting the conduit 10 into the bag 1. Each time the vending machine or dispenser performs a supply operation, the pump 2 is driven and a certain amount of beverage is appropriately taken out from the bag 1, but as the supply operation is repeated, the bag 1 contracts. When the beverage in the bag 1 eventually runs out, the spring 12 loses its pressure balance with the atmosphere and is pushed inward, and the ball 13 no longer blocks the outside air introduction hole 14. Therefore, air enters the pipe line 10 through the outside air introduction hole 14 and the valve body 16.
The remaining beverage in the pipe 10 and the small chamber 9 is pushed back into the bag 1 by the air, so the electrode 8 is exposed to the air and its resistance changes. Deficiency detected.
In this way, when it is detected that the drink is out, a lamp is turned on to warn that the drink is out, and in the case of a vending machine, the vending machine is further stopped from selling. However, in the case of a vending machine, even if the machine runs out of drinks, it does not immediately stop selling while the pump 2 is still operating, but controls so that sales stop after a predetermined operation period of the pump 2 ends. The circuit is configured. Therefore, even if the drink runs out, the drink stored at the bottom of the small chamber 9 is poured out, so that one cup's worth of drink is guaranteed. Furthermore, if it is not desirable to introduce air into the pipe 10 when the beverage runs out due to sanitary considerations, carbon dioxide gas may be introduced, and this is particularly suitable for devices that inject carbon dioxide gas into syrup beverages. .

要がなく安価である。(g) Effects of the invention According to the invention detailed above, when the difference between the outside pressure and the pressure inside the pipe reaches a predetermined differential pressure due to running out of beverage, outside air is introduced, and the introduced outside air is used to detect when the beverage runs out. It operates reliably and is easy to set up.
Moreover, since outside air is introduced only when the product is sold out, the beverage is filled into a sealed bag and supplied, so the hygienic feature of this type of beverage dispenser is not impaired. Moreover, there is no need to provide a beverage detection device for each bag, making it inexpensive.
