Description

Detailed Description of the Invention (Field of Industrial Application) The present invention is directed to a syrup vending machine that uses a bag-in box as a packaging container for syrup for cup vendors from a production factory, etc., as its source of syrup. It is related to.

(Prior art) Conventionally, syrup for cup vending from a production factory, etc., is packaged in cans, bottles, or paper packs. The packages are opened one by one and dispensed into the syrup tank inside the vending machine.

However, in the case of the above-mentioned syrup vending machine, not only is the operation of supplying syrup from another packaging container to the syrup tank complicated, but also the operation of opening the packaging container and pouring the syrup into the tank causes the syrup to leak out. This caused hygiene problems as workers were exposed to outside air and had to touch the pouring part of the container with their hands.

As an improvement on this point, a device in which a container filled with syrup for cuppender from a production factory etc. can be directly set in a vending machine has been known (Japanese Patent Publication No. 39-9352).
(Refer to Utility Model Publication No. 44-13141).

(Problems to be Solved by the Invention) In the former case, which is conventionally known, the container filled with contents from a production factory etc. is a plastic bag, and in the latter case, Since these containers are considered to be molded plastic containers, etc., when these containers are shipped from production factories, they are usually packed in cardboard boxes, etc., so the packaging process is time-consuming. Moreover, when setting it in a vending machine, it had to be taken out of the box, making it doubly time-consuming.

Furthermore, when setting these bags and containers filled with liquid in a vending machine,
It is not always easy, especially when removing the spout pipe on the spout side from the spout on the bag or container side. .

The present invention has been improved in view of these points, and is designed to prevent damage to containers filled with liquid from production plants, etc., and to prevent them from being damaged when placed in vending machines. The purpose is to make it easy to put on and take off in a hygienic manner.

(Means for Solving the Problems) In order to achieve the above object, in the present invention, a bag-in box is used as a packaging container for syrup for cuppender from a production factory, etc., and the bag-in box is used as it is for automatic sale of syrup. The above-mentioned problems are solved by using a check valve-equipped joint with a piercing blade at the tip as the supply source of the machine and as the connecting means to the pouring side.

That is, as a technical means of the present invention, in a syrup vending machine, a bag-in box is used as a packaging container for syrup for cup vendors from a production factory, etc., and this is used as a syrup supply source, The syrup supply pump of the syrup packaging container of this bag-in-box is connected with a pipe via a switching valve, a syrup detector, and a syrup reserve tank. By attaching the valved joint to the spout having a sealing membrane of the syrup packaging container, the sealing membrane is opened with the piercing blade at the tip.

(Function) The packaging container of the syrup bag-in box for the cup vending machine, which is installed in the syrup vending machine, is delivered from the production factory etc. via the syrup supply pump, the switching valve, the syrup detector, and the syrup reserve tank. The piercing blade of the joint with a check valve, which is connected by a pipe, breaks through the sealing membrane and opens the seal.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

The syrup packaging container for cup vendors used in the syrup supplying device of the present invention, that is, the bag-in box, is from, for example, a production factory. It is set inside the vending machine.

A spout b as shown in FIG. 1 is attached to this bag-in box a.

The spout main body 1 is integrally formed with ring-shaped flanges 3 and 4 that are attached to the opening 2 of the bag-in box a, and these flanges 3 and the flange 4 that is welded to the opening of the inner bag 6. An outer box 5 made of cardboard or the like of bag-in box a is held between the two.

In some cases, the spout main body 1 may be directly attached to the opening of the plastic inner bag 6 and protrude from the opening of the outer box 5.

The spout main body 1 has a cylindrical shape, and a sealing film 9 is adhered to the edge of an opening 8 in a funnel-shaped bracket 7 that is integrally formed to protrude toward the inside.

The spout main body 1 is covered with a cap 10.

In the bag-in box b having the spout a having such a configuration, the inner bag 6 is filled with syrup, and the bag-in box b is sealed with a sealing film 9 adhered to the opening 8 of the spout body 1. Although it is used as a distribution container, when the syrup is filled and sealed from a production factory, etc., and transported, and then placed in a vending machine as is, a fitting c with a check valve as described below is attached to the spout b. do.

Figures 2 and 3 show the case where the joint c with a check valve is used in different states, that is, the one in Figure 2 shows the case when the bag-in box a is used in the upright position, and the one in Figure 3 shows the case where the bag-in box a is used in an upright position. When using the product in an inverted position, that is, when the joint c with the check valve is located below the bag-in box a (Figures 5 and 7)
It shows the status of.

The joint c with a check valve has a valve body 11 and a valve seat body 12.

Tighten the holed cap 26 to the spout body 1 so that the joint c does not come off.

In order to suction and dispense the syrup from the inner bag 6, the hose d may be provided along the inner surface of the inner bag 6 as a liquid guiding path.

In the case of FIG. 3, it is sufficient to simply remove the cap 10 from the spout main body 1 and attach the joint c with a check valve without using the hose d, and the sealing membrane 9 is opened by the piercing blade 24. Then, by inverting the bag-in box a, the valve port 2 of the valve seat body 12 is opened.
Syrup is poured directly from 3.

When used as shown in FIG. 2, when the bag-in box a is in an upright position, and when suction by the pump, which will be described later, begins, the umbrella-type check valve 1
8 moves away from the valve seat 19 against the spring 17,
Hose d becomes a liquid guide path and bag-in box a
The syrup inside will be sucked up, as shown in Figure 4 A.
According to the order of B and C, the syrup decreases and the inner bag reaches 6.
When used as shown in FIG. 3, when the bag-in box a is in an inverted state, the umbrella check valve 18 is pushed against the spring 17 by the suction of the pump and 19, the syrup in the bag-in box a gradually descends in the order of A, B, and C in FIG. 5 as it is sucked out, and the inner bag 6 shrinks. In this case, hose d is not used.

Next, when the bag-in box a as described above is set in the syrup supply device of a vending machine, the overall operation will be explained based on Figs. 6 and 7. In Fig. 6, the syrup is Place the filled bag-in box a in an upright position (second
This figure shows the syrup outflow route of the syrup supply device in a vending machine when used in the case shown in the figure. Bag-in box a is connected to pipe 13 via a joint c with a check valve, and is further Connected to pipe 13' via valve e, pipe 1
3' is connected via a detection device f to a reserve tank g for the purpose of removing air.

The reserve tank g is connected to a pump p via a pipe 13'', and the pump p is connected to a cooling coil h via a pipe ₁₃₁ .

Therefore, when the pump p is operated, the syrup in the bag-in box a, which has been switched by the switching valve e, is cooled by the cooling coil h, and then flows into the pouring pipe 1.
3 It is poured out from ₂ to the cup i.

The case shown in FIG. 7 is a case where the bag-in box a is used in an inverted state (the case shown in FIG. 3), and other aspects are the same as the case shown in FIG. 6.

In the vending machine as described above, when the purchaser presses the push button, the syrup detection device f operates and the switching valve e operates, which also activates the corresponding pump p, so that the syrup is dispensed into the cup i. It will be done.

In the embodiment, the spout main body 1 has a sealing film 9, but the bag-in box a may have a spout main body that uses the plastic inner bag 6 directly as a sealing film.

In the present invention, a bag-in box a filled and sealed with syrup from a production factory or the like is used as it is, and a fitting c with a check valve that fits into the spout b is connected to the bag-in box a. Exit a cap 1
By simply unscrewing and fitting 0, preparations for dispensing the syrup from bag-in box a are completed, and when the syrup in bag-in box a is emptied by pouring, remove it and use the next one. replace it with a new one. At the time of this replacement, check valve fitting c
Since the umbrella-type check valve 18 is closed by the spring 17, outside air does not enter the pipe 13 through the joint c, and therefore the inside of the pipe 13 is not contaminated by bacteria or the like. When installing a new bag-in box a, it is sufficient to stain and clean the piercing blade 24.

It goes without saying that the vending machine of the present invention can also be used for other beverages such as juice.

(Effects of the Invention) The present invention enables bag-in boxes used as distribution containers to be used as syrup containers for cup vending machines, and to be installed in vending machines together with the bag-in boxes filled with liquid at a production factory, etc., with a check valve. It is set up with a fitting to allow syrup to be drawn directly from the bag-in box and dispensed, so when it is set in a vending machine, it does not have to be a conventional bag filled with liquid and sealed. There is no need for the trouble of taking out and setting the vending machine or container from the packaging box, and the bag-in box ensures safe transportation and it does not take much time to set or remove the vending machine.

In addition, there is no need to transfer the syrup from various containers to the onboard syrup tank as in the past, and the syrup does not come into contact with the operator's hands or the outside air.
Especially when replacing bag-in boxes, the check valve uses a spring to close the valve opening, so outside air will not enter the suction pipe through the joint.
Therefore, it will not be contaminated by bacteria or the like. Moreover, for new bag-in boxes, it is extremely hygienic because only the piercing blade portion needs to be cleaned.

Furthermore, the plastic inner bag of the bag-in box shrinks each time the syrup is pumped out, which simplifies the device compared to conventional systems in which carbon dioxide gas is pumped in each time the inside of the can or bottle is depressurized. There is no running cost required for dyeing and purifying the syrup tank, and since the inner bag and outer box of Bag-in-Box can be disposable, the cost of the container is low, and there is no need to fill it with carbon dioxide, so the flavor and flavor change. will not occur.

In short, in the present invention, the bag-in box filled with syrup and sealed can be used as is, and the sealing film can be created by simply attaching a joint with a check valve for pouring to the spout. It is easy to use and extremely hygienic as it is broken and the syrup is sucked and poured out against a check valve.
When replacing the bag-in box, even if the pressure inside the pipe is reduced, the check valve prevents outside air from being sucked into the pipe, thereby preventing contamination.
