Description

  The present invention relates to a method for filling packaged drinking water.

  Due to various environmental or space limitations, quality drinking water cannot be easily obtained everywhere and therefore there is a demand for packaged drinking water.

In the early days of packaged water, the package manufacturer sells the water after packaging it, and the user inserts the bottle mouth of the packaged potable water tank into the protruding bar of the water server so that the faucet can be inserted. When twisted, the water in the package potable water tank is discharged smoothly and can be drunk.
However, a two-way valve is installed between the initial water server and the packaged potable water tank, and when the faucet is opened, the water in the packaged potable water tank is discharged, and the outside air is discharged by the action of atmospheric pressure. I entered the package potable water tank from the way valve. In this situation, bacteria in the outside air may also enter the packaged potable water tank at the same time, and the potable water may be contaminated.

FIG. 1 is a conceptual diagram showing a conventional shrinkable tank 10. The shrinkable packaging tank is used in combination with a water server having a check valve, and a continuous recess 111 is installed in parallel in the bottle portion 11 of the shrinkable packaging tank 10. Are arranged in a circle and the longitudinal section is arranged in the form of an isosceles triangle.
When the shrinkable packaging tank 10 is used in combination with the check valve water server, the water in the shrinkable packaging tank 10 is controlled and discharged when the faucet is opened. Shrinkage occurs in the shrinkable packaging tank 10 due to interference and atmospheric pressure (see FIG. 2).
The direction and form of shrinkage of the shrinkable packaging tank 10 is limited by the installation of these recesses 111, and when water is discharged from the shrinkable packaging tank 10, external substances enter and become contaminated. Is prevented and the quality of drinking water is ensured. In addition, after use of the shrinkable packaging tank, it is automatically shrunk again and collected as waste. Furthermore, traces are generated by the shrinking operation of the packaged drinking water, so that it is avoided that the shrinkable packaging tank is collected and reused by a suspicious contractor, and the safety of the drinking water is taken into consideration. The

  The conventional technology described above, that is, the shrinkable packaging tank 10 has a shrinking effect, and in the market, many shrinkable packaging tanks 10 have a modified structure of the recess 111 in order to increase shrinkage efficiency. However, the most effective shrinkage of the shrinkable packaging tank 10 is not ensured, and the water in the shrinkable packaging tank 10 is not completely discharged, so that resources are not fully utilized. The improvement of the fault is awaited.

  Therefore, the present inventor considered that the above-mentioned drawbacks can be improved, and as a result of intensive studies, the present inventor has arrived at a proposal of the present invention that effectively improves the above-described problems by rational design.

  This invention is made | formed in view of such a conventional problem, The place made into the objective is providing the filling method which ensures the package drinking water from which a package drinking water is discharged completely.

In order to solve the above-described problems and achieve the above object, a filling method for securing packaged drinking water from which packaged drinking water according to the present invention is completely discharged is for shrinkable packaging having a tank part and a bottle mouth part. A tank is provided, and a shrinkable guide unit is formed in the tank portion, and the tank portion of the shrinkable packaging tank is shrunk along the shrinkable guide unit under pressure due to water discharge, And providing a shrinkable packaging tank having a volume before shrinkage before shrinkage of the shrinkable packaging tank and having a volume after shrinkage after shrinkage of the shrinkable packaging tank;

  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to the embodiments described below.

(First embodiment)
The filling method for securing the packaged drinking water from which the packaged drinking water of the present invention is completely discharged is applied to a shrinkable packaging tank and a water server to be discharged only in one direction, and includes the following steps.
In the step (I) of providing a shrinkable packaging tank, a shrinkable packaging tank 20 having a tank portion 21 and a bottle mouth portion 22 is provided, and a shrinkable guide unit 211 is formed in the tank portion 21. Then, the tank portion 21 of the shrinkable packaging tank 20 is shrunk along the shrinkable guide unit 211 under pressure, and the shrinkable packaging tank 20 has a volume V1 before shrinkage before shrinking. The shrinkable packaging tank 20 has a volume V2 after shrinkage, and a filling instruction line 212 is further provided on the outer surface of the tank portion 21 of the shrinkable packaging tank 20.
In the filling step (II), the shrinkable packaging tank 20 includes the filling water having the water volume V3 and the filling having the material volume V4, and the sum of the water volume V and the material volume V4 under normal temperature and normal pressure. Is equal to the volume V1 before shrinkage, that is, V1 = V3 + V4, and the volume V4 of the material under normal temperature and normal pressure is larger than the volume V2 after shrinkage, that is, V4> V2, and the filling is air or liquid nitrogen (Nitrogen at room temperature) and the filling material is liquid nitrogen, the filling process (II) is filled with liquid nitrogen, and once the liquid nitrogen is output into the shrinkable packaging tank 20 at room temperature and normal pressure In this embodiment, water is filled at the position of the filling instruction line when transformed into nitrogen in a gaseous state.
In the packaging step (III), water and the filling are closed in the shrinkable packaging tank 20.

  The above is the filling method for ensuring the packaged drinking water from which the packaged drinking water according to the present invention is completely discharged, and the shrinkable packaging tank 20 is filled by the above-described method and then can be shrunk at the time of use. The tank 20 is used by being inserted into the water server with the bottle mouth portion 22 facing downward. In use, the bottom of the shrinkable packaging tank 20 is oriented upward and is located below the water level in the shrinkable packaging tank 20 so that the filling in the shrinkable packaging tank 20 Located above.

After the water is discharged from the shrinkable packaging tank 20 through the water server, the water server only discharges water in one direction. Therefore, external air cannot enter the shrinkable packaging tank 20 from the water server. Thereby, after draining the shrinkable packaging tank 20, the shrinkable packaging tank 20 is shrunk along the shrinkable guide unit 211 by the action of atmospheric pressure, and the shrinkable packaging tank 20 is extremely shrunk. Only the volume after shrinkage remains in the shrinkable packaging tank 20.
In the draining process of the shrinkable packaging tank 20, the filling material filled in the shrinkable packaging tank 20 is positioned above and is not discharged together with water. For this reason, when the shrinkable packaging tank 20 is shrunk until only the volume after shrinkage remains, the volume of the filler positioned in the shrinkable packaging tank 20 becomes larger than the shrinkage volume, If water still remains in the possible packaging tank 20, pressure on the remaining water is generated by the filling, and the water in the shrinkable packaging tank 20 is discharged from the shrinkable packaging tank 20 and shrinks. Since the water in the possible packaging tank 20 is completely drained and used and the energy is fully utilized, the waste of resources is reduced.
In this state, the most preferable shrinkage effect is generated in the shrinkable guide unit 211 by the pressure generated with respect to the packaging tank 20 in which the filling can shrink.

  From the above configuration, the method for filling package drinking water according to the present invention is applied to various shrinkable packaging tanks 20, and the shrinkage efficiency of the shrinkable packaging tank and the difference in the form of the shrinkable guide unit 211 are different. Regardless, the water in the shrinkable packaging tank 20 is completely discharged and used only by filling with the packaged drinking water filling method according to the present invention, and the water in the shrinkable packaging tank 20 is used. Is no longer left, and the energy usage rate is reliably increased.

  As mentioned above, although embodiment of this invention was explained in full detail with reference to drawings, the concrete structure is not restricted to this embodiment, The design change etc. of the range which does not deviate from the summary of this invention are included.
