A packaging drinking water filling method for ensuring complete discharging the packaged drinking water, which controls the volume of water and the filling material in the shrink packaging bucket during the filling step to make the volume of the filling material bigger than the contraction volume of the shrink packaging bucket, such that the filling material can produce pressure on the shrink packaging bucket after water is discharged from the shrink packaging bucket, thus achieving the best contraction effect of the shrink packaging bucket and ensuring that water can be discharged from the shrink packaging bucket completely.

Description

Packaging drinking water filling method for ensuring complete packaging of drinking water

The present invention provides a packaged drinking water filling method for ensuring complete drainage of packaged drinking water, which is related to a method of filling a packaged drinking water.

According to various environmental or space constraints, it is not easy to obtain quality-assured drinking water in any place, so there is a demand for packaging drinking water.

The early packaged drinking water is sold by the packaging factory after the water is packaged, and the user only needs to insert the bottle mouth of the packaging drinking water bottle into the ejector rod of the water dispenser, and the package can be smoothly taken out through the control of the faucet. The water in the bucket is used.

However, a two-way valve is arranged between the early drinking fountain and the packaged drinking water tank. After the faucet is opened, the water in the packaging drinking water tank is discharged, and under the action of one atmosphere, the outside air enters the packaging by the two-way valve. In the drinking water tank, under this condition, it is possible to bring bacteria from the outside air into the packed drinking water tank at the same time, causing drinking water pollution.

Therefore, as shown in FIG. 1 , an improved shrink wrapper 10 is used. The shrink wrapper is used in conjunction with a water dispenser having a one-way valve. The body portion 11 of the shrink wrap 10 is provided with a continuous groove 111 in parallel. The cross section of the groove 111 is a circular shape, and the longitudinal section is configured as an isosceles triangle. When the shrink wrap 10 is used with the water dispenser of the check valve, when the faucet is opened to control the shrink wrap 10 When the water inside is discharged, the shrink wrapper 10 is contracted by the blocking of the check valve and the atmospheric pressure, as shown in FIG. 2, and the shrink wrap 10 is restricted by the arrangement of the grooves 111. The direction and type of contraction are thereby prevented from being contaminated by the intrusion of external substances when the shrink wrap 10 is discharged, thereby ensuring the quality of the drinking water. Moreover, after the shrink-wrapped water bucket is used, it can automatically shrink, which is convenient for waste recycling, and further, can also cause traces of the shrinking action of the packaged drinking water, thereby avoiding unscrupulous recycling of the shrink-wrapped bucket to avoid drinking water. Security concerns.

However, even if the shrink wrapper 10 has a shrinking effect, there are many shrink wrappers 10 on the market which aim to change the structural form of the groove 111 in order to improve the shrinking efficiency, but it is still impossible to ensure that the shrink wrapper 10 is most effectively shrunk. It is also impossible to ensure that the water in the shrink wrapper 10 can be completely discharged, so that there is still a shortage of resources that cannot be fully utilized for improvement. In view of this, the inventors have diligently studied and further conceived, and after many research and development experiments, finally invented a packaging drinking water filling method for ensuring complete discharge of drinking water.

The invention provides a packaging drinking water filling method for ensuring complete water discharge of packaged drinking water, the main purpose of which is to improve the lack of waste of resources of the general shrink packaging bucket which cannot ensure the shrinking effect and still residual water to be improved.

To achieve the foregoing objective, the present invention provides a packaged drinking water filling method for ensuring complete water discharge of packaged drinking water, which is suitable for a shrinkable packaging bucket and a water dispenser which only provides one-way water discharge, and includes:

Providing a shrink wrap bucket step, providing a shrink wrap bucket having a barrel body and a bottle mouth, and forming a shrink guiding unit on the barrel portion, the barrel portion of the shrink wrap bucket being pressurized Shrinking along the shrinkage guiding unit; and the shrink wrapper bucket has a pre-shrinkage volume before shrinking, and the shrink wrapper bucket has a contracted volume after shrinking;

Filling step, filling the shrink wrap bucket with water and a filling mass, the sum of the volume of the filling water and the filling mass at normal temperature and pressure is equal to the volume before shrinkage; and the volume of the filling material at normal temperature and pressure is greater than the filling volume Volume after contraction;

The packaging step encloses the water and the filling in the shrink wrap.

The present invention controls the volume of the filling material to be larger than the shrinkage volume of the shrink packaging drum by controlling the volume of water and the filling material filled in the shrink wrap bucket during the filling step, thereby making the filling quality in the shrink wrap bucket After the water is discharged, pressure is generated on the shrink-wrapped bucket, so that the shrink-wrapped bucket can be extremely contracted, and at the same time, the water in the shrink-packed bucket can be completely discharged, avoiding energy waste and improving energy utilization.

Embodiments of the present invention provide a packaged drinking water filling method for ensuring complete water discharge of packaged drinking water, which is suitable for a shrinkable packaging water bucket and a water dispenser that only provides one-way water discharge, and includes:

A shrink wrapper step (I) is provided, and a shrink wrapper 20 is provided. The shrink wrapper 20 has a barrel portion 21 and a bottle opening 22, and a shrink guiding unit 211 is formed on the barrel portion 21, and the shrinkage is formed. The barrel portion 21 of the packaging water tub 20 is contracted along the contraction guiding unit 211 by pressure; and the shrink-wrapped water tub 20 has a pre-contraction volume V1 before being contracted, and the shrink-wrapped water tub has a contracted volume V2 after contraction; and the contraction The outer surface of the barrel portion 21 of the packaging water tub 20 can be further provided with a filling prompt line 212;

Filling step (II), the shrink wrap 20 is filled with water and a filling material, wherein the water has a water volume V3, the filling has a filling volume V4, the water volume V at normal temperature and pressure and the filling volume The sum of V4 is equal to the pre-contraction volume V1, that is, V1=V3+V4; and the filling volume V4 at normal temperature and normal pressure is greater than the post-contraction volume V2, that is, V4>V2; the filling may be air or liquid nitrogen ( When the filling material is liquid nitrogen, when the filling step (II) is filled with liquid nitrogen, once the liquid nitrogen is output to the shrinking packaging water tank 20 at normal temperature and normal pressure, it will be transformed into a gaseous state. Nitrogen; and in this embodiment, the filling is filled with water to the filling line;

In the packaging step (III), the water and the filling material are enclosed in the shrink wrapper 20.

The above is the packaging drinking water filling method for ensuring complete water discharge of the packaged drinking water. When the shrink packaging water tank 20 is filled by the above method, the shrink packaging water tank 20 is inserted in the downward direction of the bottle opening 22 when used. When the water dispenser is in use, the bottom of the shrink wrap bucket 20 faces upward, and the water in the shrink wrap 20 is located below, and the filling quality in the shrink wrap 20 is located above;

After the water is discharged from the shrink-wrapped water tub 20 via the water dispenser, since the water dispenser only provides one-way water discharge, the outside air cannot enter the shrink-wrapped water tub 20 from the water dispenser, so after the shrink-wrapped water tub 20 discharges water, Under the action of one atmosphere, the shrink wrap 20 is contracted along the shrink guiding unit 211. When the shrink wrap 20 is contracted to the uncontractable state, only the contracted volume remains in the shrink wrap 20, and During the process of discharging the shrink-wrapped water tub 20, the filling material filled in the shrink-wrapped water tub 20 is located above without being discharged with water, and therefore, when the shrink-wrapped water tub 20 is contracted until only the contracted volume remains, The volume of the filling material located in the shrink wrapper 20 is greater than the contracted volume, so that when there is still residual water in the shrink wrap 20, the filling will stress the residual water, forcing the shrink wrap The water in the 20 is discharged from the shrink wrap 20 to ensure that the water in the shrink wrap 20 can be completely discharged, ensuring that the energy can be fully utilized. The situation of reducing waste of resources occurs; and in this state, the pressure generated by the filling material on the shrink wrapper 20 can also cause the shrinkage guiding unit 211 to produce an optimum shrinking effect.

In summary, the filling method of the packaged drinking water of the present invention is applicable to various shrink wrap buckets 20, regardless of the shrinkage efficiency of the shrink wrap bucket and the form of the shrinkage guiding unit 211, as long as the filling method of the packaged drinking water of the present invention is used. Filling ensures that the water in the shrink wrap 20 is completely drained, avoiding shrinking the residual water in the wrapper 20 and indeed increasing energy usage.
