DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid capable of discharging a fixed amount of liquid while maintaining a constant quality for a long period of time even in a neutral beverage without external air entering a liquid storage portion at the time of liquid discharging. It relates to a quantitative dispensing device.

[0002]

2. Description of the Related Art Conventionally, as a liquid dispensing apparatus for dispensing a fixed amount of beverage liquid into a cup, a cup dispensing type vending machine, a button pressing type liquid dispenser and the like are known. A cup dispensing type vending machine and a liquid dispenser (hereinafter, simply referred to as a liquid dispensing device) generally store a beverage in a tank (liquid storage section) in the device, and directly inject the liquid therethrough via an electromagnetic valve or the like. Due to this structure, outside air enters into the tank at least when the tank is filled with liquid or when liquid is poured out of the tank, and the stored liquid is liable to rot or oxidize. In addition, in the conventional liquid dispensing apparatus, since the liquid is supplied to the cup via a valve and a nozzle provided in the apparatus, these parts are easily contaminated, and there is a problem in hygiene. Therefore, in particular, coffee and tea, which oxidize immediately upon contact with air and deteriorate in quality, have a problem that conventional liquid metering devices cannot always provide high quality and provide such beverages. It is not preferable to supply the liquid in small quantities in the liquid dispensing device.

[0003] On the other hand, in the case of a neutral beverage such as oolong tea or coffee which is easily oxidized or decomposed, the liquid dispensed by these liquid dispensing apparatuses has a gas barrier property to prevent spoilage and deterioration in the distribution process. Tall bags are supplied aseptically at the factory into containers called bag-in-boxes built into cardboard boxes. Thereby, even a neutral beverage can be stored for a long time at room temperature, and the distribution cost is reduced. However, as described above, from the bag-in-box, there is no means for dispensing a fixed amount of the internal solution little by little without allowing the liquid inside to come into contact with air. It was not possible to divide and provide while maintaining a certain level of quality. For this reason, it has not been possible in terms of quality conservation to store, for example, a neutral beverage that is easily contaminated with bacteria or oxidized as a raw material liquid in a vending machine, dilute the liquid at the time of discharging the liquid, and pour it into a cup.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems of the conventional liquid dispensing and dispensing apparatus, and the liquid in the container does not come into direct contact with air, and Dispenses a fixed amount of liquid without contacting parts such as the nozzle of the device.Even if the liquid is easily oxidatively degraded, such as a neutral beverage, there is no risk of spoilage or oxidative deterioration. It is an object of the present invention to provide a liquid dispensing apparatus capable of maintaining and supplying a constant quality for a long period of time until the supply is completed.

[0005]

According to the present invention, there is provided a liquid dispensing apparatus for dispensing a liquid, comprising: a dispensing portion including an inlet, a dispensing bag, and a spout, communicating with the liquid storage bag. Device for discharging a liquid from the container, wherein the container is held in a state in which a constant-rate pouring portion is hung, and the container is movably provided with respect to the inlet, and presses the inlet to close the inlet. An injection valve, and an injection valve movably provided with respect to the injection port to press the injection port to close the injection port. The inlet valve and the spout valve are configured to be connected to each other by a holding plate that rotates about a fulcrum so that the inlet valve and the spout valve move in directions opposite to each other. A fixed amount of liquid is stored in the outlet, and when the outlet is opened, the inlet is closed and the liquid in the outlet is closed. To become so as to dispense is obtained by solved by adopting a structure characterized.

In the holding plate, the end on the outlet valve side is connected to a valve drive actuator, and the end on the inlet valve side is connected to a tension spring, and the outlet valve closes the outlet by the tension spring. It is configured to be urged in the direction, and the spout is reliably closed by the spring force of the tension spring except when the liquid is poured out. Further, a liquid extruding plate which is provided so as to be movable substantially vertically with respect to the fixed amount dispensing bag, and which presses the fixed amount dispensing bag at the time of liquid dispensing, and a fixed amount dispenser disposed opposite to the liquid extruding plate. It had a dispensing bag holding lid, and a fixed amount dispensing bag holding space was formed between the liquid extruding plate and the fixed amount dispensing bag holding lid. Further, the liquid push-out plate is provided so as to be adjustable in the direction of the fixed-rate dispensing bag holding cover, and by adjusting a distance between the liquid pushing-out plate and the fixed amount dispensing bag holding cover, the liquid is poured into the fixed amount dispensing bag. It was configured so that the amount of liquid to be applied could be adjusted. In addition, the liquid push-out plate is driven by an actuator so as to press the fixed amount dispensing bag via a plurality of liquid push-out plate pushing springs when the liquid is poured out. The liquid pushing plate pressing spring, which is located closer to the inlet valve, is set to have a stronger spring force than the spring located closer to the outlet valve.

[0007]

Since the spout valve and the inlet valve move in opposite directions, the spout is always closed when the inlet is open. For example, the inlet valve is always open when the inlet valve is open. If the outlet valve is closed, a fixed amount of liquid flows into the fixed amount pouch from the liquid storage portion and is stored. At this time, the spout valve presses the spout portion by the spring force of the tension spring, and the spout is reliably kept closed for a long time without requiring any special energy. At the time of liquid dispensing, the valve drive actuator is operated and the holding plate is rotated against the tension spring, whereby the inlet valve closes the inlet and cuts off the communication between the storage bag and the fixed amount dispensing bag. At the same time, since the spout valve opens the spout, outside air does not enter the liquid reservoir during pouring. In addition, the liquid does not come into contact with the equipment in the apparatus at all until the end of the dispensing, and a constant amount of the liquid can be repeatedly dispensed. It is possible to eliminate anxiety about hygiene of the delivery device. Therefore, by this apparatus, from a container in which an aseptic-filled liquid storage unit and a fixed-quantity pouring unit are integrated at a factory, air is not introduced into the liquid storage unit, and only the inner surface of the container is contacted to determine the amount. The liquid stored in the liquid storage section is completely shut off from the outside air because it can be divided and poured out. be able to. Therefore, according to the present apparatus, the present invention can be applied to the dispensing of neutral beverages, particularly coffee, oolong tea, and the like, which are unsuitable for dispensing from a dispenser because they are easily oxidized and decomposed.

Further, at the time of liquid pouring, the liquid extruding plate pressing spring is compressed, and the liquid extruding plate slowly presses the side surface of the fixed amount dispensing bag with a weak force at first, and gradually presses harder and faster as the spring is compressed. Therefore, the liquid is discharged from the outlet at a substantially constant flow rate. Then, the liquid pushing plate pushing spring strengthens the spring force near the inlet valve side, so that the liquid pushing plate pushes the fixed amount dispensing bag in a forward tilt state in which the upper side of the fixed amount dispensing bag is pressed slightly strongly. It is possible to satisfactorily dispense the liquid in the fixed amount dispense bag to the end without leaving the liquid. Since the distance between the liquid extruding plate and the fixed amount dispensing bag holding plate at the time of liquid injection into the fixed amount dispensing bag can be adjusted, the filling amount of the fixed amount dispensing bag can be adjusted in a small amount. For example, the volume of a fixed quantity dispensing bag is 30 cc.
In this case, the amount to be dispensed at one time can be adjusted between 30 cc and 25 cc.
