Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is a fixed-quantity pouring method capable of pouring a fixed amount of liquid filled in a bag while maintaining a constant quality for a long period of time without external air or bacteria entering the bag during pouring. The present invention relates to a bag with an outlet and a bag-in-box using the bag.

[0002]

2. Description of the Related Art Conventionally, coffee, black tea, oolong tea, etc. have been used as a means for supplying a raw material liquid for a cup type vending machine or a liquid dispenser that dispenses a beverage liquid into a cup, which has a low acidity which is easily contaminated by oxidation and bacteria. In the case of beverage liquid and neutral beverage liquid, a bag called a bag-in-box in which a bag having a high gas barrier property is housed in a cardboard box is aseptically filled and provided. As a result, even beverages that are prone to oxidative deterioration can be stored at room temperature for a long period of time, reducing distribution costs.

However, liquid dispensers such as cup-type vending machines and liquid dispensers generally have a structure in which the beverage is poured directly from the tank in the apparatus, so that the beverage is transferred from the bag to the tank. There must be. At least when the liquid is poured out of the tank, the outside air directly enters the tank, so that neutral beverages and the like that are prone to decay and oxidative deterioration can be stored for only a short period of time. Therefore, even if it is aseptically filled in the factory, there is a problem in that, after being transferred to these liquid pouring devices, oxidation and deterioration proceed and a certain quality cannot be maintained. In particular, coffee, tea, which oxidizes and deteriorates quality immediately on contact with air,
Oolong tea and the like have a problem that they cannot always be provided while maintaining high quality in the conventional liquid pouring device, and they cannot be applied to the liquid pouring device dividedly provided in small amounts. Also,
In the conventional liquid pouring device, since the liquid is supplied to the cup through the nozzle provided in the device, the nozzle is easily contaminated and there is a problem in hygiene.

[0004]

DISCLOSURE OF THE INVENTION The present invention is intended to solve the above-mentioned problems in the conventional liquid pouring device for dividing a small amount of a neutral beverage or the like into a liquid pouring device directly from a bag. The solution can be dispensed quantitatively without contacting the dispensing device, etc., and the inner solution in the bag does not come into direct contact with air even when it is dispensed, so there is no risk of the inner solution decaying or oxidative deterioration. , A bag with a fixed volume dispensing part for a liquid dispensing device capable of supplying a liquid with a constant quality for a long period of time even if it is an internal solution such as a neutral beverage that is severely oxidized and deteriorated, and a bag-in-box using the bag. The purpose is to provide.

[0005]

In order to solve the above problems, the bag with a fixed amount pouring portion of the present invention is made of a flexible material having a high gas barrier property, and has a liquid storage portion having a liquid filling port which can be sealed on the side wall. ,
The liquid storage part is connected to a fixed amount pouring part, and the fixed amount pouring part is connected to the liquid storage part, an injection port part, a fixed amount pouring bag connected to the other end of the pouring part, the fixed amount pouring part. By providing a spout for pouring the liquid from the bag to the outside, and by providing a configuration characterized in that the whole is formed in a sealed manner,
I was able to solve it. A set hole is formed in the peripheral portion of the fixed amount dispensing bag so that the fixed amount dispensing bag can be easily and accurately attached to the liquid fixed amount dispensing device. In addition, the bag with a fixed amount dispensing portion formed as described above, and the bag with a fixed amount dispensing portion can be stored in a state where the liquid reservoir is filled with a liquid and the fixed amount dispensing portion is folded, and By combining a box with a rupturable weakened part formed on the wall surface to form the extraction window for pulling out the fixed quantity dispensing part to the outside, the whole box can be attached to the fixed quantity dispensing device for a long time. We were able to obtain a bag-in-box that can be dispensed quantitatively while maintaining a constant quality for a certain period.

[0006]

[Function] Since the fixed amount dispensing bag is provided with the liquid storage bag, which is a liquid storing portion, through the inlet port, and also has the spout portion for pouring the liquid from the fixed amount dispensing bag to the outside. The inlet and outlet can be opened and closed independently. Therefore, if it is attached to the liquid fixed amount dispensing device and the inlet is opened and the outlet is closed, the liquid can flow from the liquid storage bag into the fixed amount dispensing bag to store the fixed amount, By closing the inlet to block the communication between the liquid storage bag and the fixed amount dispensing bag and opening the outlet, the liquid in the fixed amount dispensing bag can be discharged to the outside. Since the spout is closed during the inflow into the fixed amount pouch and the inlet is closed during the pouring out from the fixed pour bag, the outside air never enters the liquid storage bag. Further, since the liquid is poured out without contacting with the instrument or the like in the liquid fixed amount dispensing device, there is no possibility of being contaminated. Then, if the bag-in-box provided with the bag with the fixed amount pouring unit is applied to a cup-type liquid pouring device such as a vending machine in a state where the fixed amount pouring unit is pulled out from the fixed amount pouring unit drawer window,
It is possible to dispense a fixed amount of liquid without worrying about contamination, and it is possible to eliminate the hygiene concerns of conventional vending machines.

As described above, according to the bag of the present invention, air is not introduced into the liquid reservoir from the bag aseptically filled in the factory, and only the inner surface of the bag is brought into contact with the bag so that the bag is divided into a predetermined amount and poured out. Therefore, even if the solution is stored for a long period of time, the internal solution does not become contaminated with bacteria or is oxidized, and a certain quality can be maintained until the end of use. Accordingly, it is most suitable as a low-volume beverage or a neutral beverage, particularly a quantitative dispensing bag for beverages that are apt to oxidize or decompose and were not suitable for dispensing from a liquid dispensing device. For example, by filling with a 5 times concentrated liquid of a beverage liquid and diluting it with water or hot water at the time of pouring, 1 / th of the conventional bag amount is obtained.
5, the distribution cost and storage cost of the bag is 1 /
The number can be reduced to 5, and it can contribute to saving resources and solving the problem of dust due to empty bags. Further, since the bag-in-box of the present invention can be composed of cardboard and a synthetic resin film, it can be treated as incinerated waste after use.
