Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to a manufacturing method for manufacturing a portable drink bag made of synthetic resin, which is used for distributing drinking water to victims in a disaster area such as an earthquake, tsunami or fire. In particular, the present invention relates to a manufacturing method suitable for a portable bag filling device.

[0002]

2. Description of the Related Art Generally, in the disaster area, when water supply becomes unavailable, a water truck is dispatched to distribute drinking water. A water truck is a tank truck equipped with a large-capacity water tank, and victims receive drinking water in containers such as buckets and kettles and bring it back to the evacuation site for use.

When water is supplied in such a form, there is a problem that the distribution work is troublesome and a considerable amount of water is spilled by vibration before the person who receives the water returns to his home. Furthermore, it is often difficult to store the product in a sanitary state for a long time even after taking it back to the evacuation site.
Therefore, water and portable water tanks filled in PET bottles are used for disaster areas.

However, replenishing the bottle with the large amount of water required in the disaster-stricken area or pre-packing it in the bottle causes various problems in transportation in a disaster area where traffic is impaired. Also, in terms of storage, an extremely wide warehouse was required in each place, and there were also hygiene concerns such as the decay of drinking water. Also, there were difficulties in storage and transportation.

[0005]

In order to solve such a problem of the present situation, it is necessary to transport drinking water to a disaster area with a water truck, and to bag and distribute it at the site for both efficiency and hygiene. However, it is natural that it is necessary to be able to bag quickly when trying to pack in a disaster site, and there is not always a required sanitary water source,
In addition, even when sterilized in water and packed in bags,
In order to minimize water spoilage, it is urgently required that nothing other than water, such as air, enter the bag.

[0006]

In order to solve the above-mentioned problems, the present invention accommodates a material roll and a bagging means for drinking water inside a portable box, and is stripped from the material roll. After the material is sewn into a tubular shape, the step of closing the end portion to form a preliminary container, the step of pouring water into the preliminary container, and the opposite wall surface of the preliminary container that has been poured from the water level of the drinking water. It is fused and sealed below.

[0007]

The band-shaped material unwound from the material roll is sewn into a tubular shape inside the box, and the bottom is closed to form a preliminary container having an open upper surface. When drinking water is poured into the spare container, the spare container is closed at a position lower than the water level of the drinking water injected therein, and the drinking water is sealed inside. Therefore,
At the time of sealing, the air above the surface of the drinking water is excluded without being enclosed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the illustrated embodiments. In the figure, 10 is a portable beverage bag manufacturing apparatus.
The manufacturing apparatus 10 includes a box 12 having wheels 11 and a water inlet 13
And a faucet 14 are provided, and a sterilizing agent adding means 16, a stirring means 17, and a bagging means 18 are connected to a drinking water pipe line 15 which connects the water inlet 13 and the faucet 14.
Reference numeral 19 is an outlet for drinking water packed in a bag.

Reference numerals 21 and 22 denote addition means 16 and stirring means 17.
Is an on-off valve for interposing or excluding the inside of the pipe 15 and both valves are opened and closed in opposition to each other. That is, the on-off valve 2
2 is closed and the opening / closing valve 21 is opened, the addition means 16 and the stirring means 17 are substantially excluded from the conduit 15. On the contrary, if the opening / closing valve 22 is opened and the opening / closing valve 21 is closed, the addition means 16 and stirring are stirred. Means 17 are inserted into the conduit 15.

The bagging means 18 has a material roll 32 in which a band-shaped material 31 made of a synthetic resin film is wound around a roll. As shown in FIG. 3, the band-shaped material is made of a so-called laminate material in which polyethylene PE having a relatively low melting point and nylon NY having a relatively high melting point and high mechanical strength are laminated in two layers.

The strip-shaped material 31 unwound from the material roll 32 is nipped and rolled by the left and right rolls 33, 33,
The polyethylene PE having a low melting point is placed inside and the edges on both sides are fused and sewn by the roller electrodes 34 of the high frequency sewing machine to form a tubular shape. Further, the lower end thereof is melt-sewn by the edges of the plate electrodes 35 of the high-frequency sewing machine to form a bottom, and the band-shaped material 31 becomes the preliminary container A.

Reference numeral 36 is a water injection nozzle. Water injection nozzle 36
The base end of is connected to the drinking water pipe 15, and supplies drinking water into the preliminary container A. 37 is a cutter for cutting, which cuts the packed water into individual bag units to make a portable drinking water bag.

Next, the process of producing drinking water according to this embodiment will be described. First, when the manufacturing apparatus 10 is transported by a truck or the like to the vicinity of the disaster area, the wheels 11 are moved to the place of use. When public water can be used as a water source at the place of use, the water inlet 13 is connected to the water, and when water cannot be used, water is supplied from a swimming pool such as a school or a relatively clean river by a water supply facility (Fig. Connected (not shown).

When the manufacturing means 10 is connected to the water supply,
The on-off valves 21 and 22 provided in the pipeline 15 are operated to disconnect the adding means 16 and the stirring means 17 from the pipeline 15. When the manufacturing apparatus 10 is connected to a water source which is not for drinking, the adding means 16 and the stirring means 17 or the filtering means (not shown) are operated. Therefore, the water that has entered from the water inlet 13 is purified and sterilized by the addition means 16 and the stirring means 17, or foreign substances are removed by the filtration means, and then flows through the pipe line 15 as drinking water, and the water injection nozzle 36 and Faucet 14
Supplied to

On the other hand, the strip-shaped material 31 unwound from the material roll 32 is sent in the longitudinal direction, and in the process, the bottoms fused by the left and right rolls 33, 33 and the high frequency sewing machine in the direction orthogonal to the longitudinal direction. A cylindrical preliminary container A having a shape is formed. At that time, the preliminary container A is arranged in the vertical direction, and drinking water is supplied from above by the water injection nozzle 36. The amount of drinking water required to reach a higher water level L than the lid portion of the auxiliary container A is injected.

Next, the plate electrodes 35, 3 of the high frequency sewing machine
5 is advanced, the spare container A is sandwiched at a portion lower than the water level L, and a high-frequency current is passed. Since a material having a low melting point is arranged on the inner surface of the preliminary container A, it can be easily fused even in water. Thus, the portion below the plate-like electrode 35 is sealed to form the bag B, and there is no water other than the water melted in the bag. Since the bags B are successively connected like a sausage and come out, they are cut by the cutter 37, become independent, and are discharged from the take-out port 19.

Of course, the beverage produced by the method and apparatus of the present invention is not limited to drinking water and can be used for other purposes.
