Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a packaging method applied for transportation of goods requiring high internal pressure in packaging, for example, appreciation fish such as tennis balls, goldfish, and tropical fish.
[0002]
[Prior art]
Conventionally, in order to bring the inside of a packaging container into a high pressure state, a high internal pressure is obtained by filling a can, a PET container or the like with a content in a high pressure chamber and opening the container. In addition, if a high internal pressure can be obtained in the form of a bag, a check valve is attached to the bag in advance, the contents are filled, the bag mouth is closed, and air is sent through the check valve to increase the internal pressure. It has a mechanism like this. However, these conventional techniques have a problem of disposal of containers after use in the case of containers. On the other hand, in the case of a bag having a check valve, the check valve is expensive, and there is a problem that a special device is required for its installation, resulting in a very high total cost. ing.
[0003]
It is an object of the present invention to provide a packaging method that can eliminate the above-mentioned drawbacks.
[0004]
[Means for Solving the Problems]
In order to achieve the above object, in the invention according to claim 1, in the packaging method, a. The contents of water and goldfish or tennis balls are contained in an airtight bag formed of a plastic laminate film, and the bag mouth is sealed by heat sealing while leaving air in the bag.
b. Next, the bag containing the contents and having air remaining therein is bound from the outside using a clip, a band, or a string at a position avoiding the contents, Decrease the volume and increase the air pressure in the bag by this reduction,
c. It is characterized by this .
[0005]
[Action]
Containing the contents in the bag, the mouth of the bag while leaving a air bag to seal the heat-sealed to the mouth (volume of air at this time is adjusted by the final required internal pressure ). Then, by attaching tie part of bags (depending on the form of the contents may be at the edge of the bag in the middle of the bag) in such a clip or band or string, this decrease by reducing the volume product of the bag, the bag increasing the air pressure. Incidentally, if necessary a higher air pressure, clamping the bag 2 points.
[0006]
The bag used at this time is preferably in the form of a tube, but it may be in the form of a sealed gusset or a gusset.
The material of the film is not particularly limited, but a laminate film containing aluminum is preferable when long-term storage is required.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention described in claim 1 will be described in detail with reference to FIGS.
First, a plastic laminate film having a strength that can withstand internal pressure is used as the material of the bag 1. The form of the bag 1 is not particularly limited, such as a three-sided seal, a back-fitting, a palm-fitting, or a gusset bag. The bag 1 is sealed by putting water 3 and goldfish 2 as shown in (b) and heat-sealing the mouth 4 as shown in (c).
[0008]
Next, as shown in (d), tied mouth side of the bag 1 with clips 5, to reduce the volume product of the bag 1. In this way, the bag 1 is increased correspondingly air pressure capacity product is reduced, the bag 1 is a pressure suitable for the transport of goldfish 2.
Similarly, in FIG. 2, the tennis ball 6 is sealed in the bag 1, and then the center is clamped with the clip 5 to increase the internal pressure so as to obtain an internal pressure required for transportation and storage.
[0009]
In addition, although the shape of the bag 1 is free according to the packaging form of the contents, the position and shape to be tied with the clip 5 may be determined in advance. For example, a string, a band, or the like other than the clip 5 may be used. If possible, the internal pressure may be increased by sealing and then heat-sealing a part of the space.
A bag is easy to set the position where a rectangular thing binds. The inside of the bag 1 may be air, various gases, gas such as oxygen, or filled water or seawater.
[0010]
【The invention's effect】
The present invention can easily increase the air pressure in a bag simply by tying the bag from outside with a clip or the like after the contents are contained in an airtight bag formed of a plastic laminate film and the bag is sealed. As a result, the cost is greatly reduced as compared with conventional cans, PET containers, and check valves. It also leads to a significant volume reduction of waste after use. Furthermore, it is possible to easily adjust the pressure depending on the amount of air to be filled and the amount and degree of tightening. Also, without requiring special equipment, it is possible to increase the internal pressure of the bag easily.

Claims (1)

a. The contents of water and goldfish or tennis ball are contained in an airtight bag formed of a plastic laminate film, and the bag mouth is sealed by heat sealing while leaving air in the bag.
b. Next, the bag containing the contents and having air remaining therein is bound from the outside using a clip or a band or a string at a position avoiding the contents, Decrease the volume and increase the air pressure in the bag by this reduction,
