JPH11189219A - Impact absorbing and packaging method, and packaging bag - Google Patents

Abstract

PROBLEM TO BE SOLVED: To reduce the volume of an impact absorbing and packaging material. SOLUTION: A glass 5 is placed in an inner bag 2 of a bag of the double structure comprising the inner bag 2 and an outer bag 3, both the inner bag 2 and the outer bag 3 are sealed as the gas left behind, and both the inner bag 2 and the outer bag 3 are tightened to reduce the volume in both bags, and to increase the internal pressure in both bags. The glass 5 is protected from the impact thereby.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging method having a shock absorbing function and a shock absorbing packaging bag.

[0002]

2. Description of the Related Art For the protection of products, many cushioning materials or molding trays according to the shape of products have been used for the transportation of pottery, glassware and precision equipment. The disposal of materials and forming trays has become a major problem. In addition, when a molded tray is used, it is necessary to make a tray according to the shape of each product, and the cost is large.

[0003] For the transportation of easily breakable goods, cushioning materials such as air cushions, urethane cushions, paper, etc., or molding trays shaped according to the product shape, or
Styrofoam and cardboard product holders have been used. However, they occupy a large volume as waste after the products are taken out, and they have to be made in accordance with the shape of each product, which is expensive.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a shock absorbing packaging method and a bag for shock absorbing packaging which can greatly reduce the volume of the shock absorbing packaging means after use.

[0005]

In order to achieve the above object, according to the first aspect of the present invention, the contents are put on the inner bag side of a double-layered bag composed of an inner bag and an outer bag. By sealing both the inner bag and the outer bag with the gas remaining, then tightening both the inner bag and the outer bag, reducing the volume in both bags and increasing the internal pressure in both bags, It is characterized by protecting objects from impact.

According to a second aspect of the present invention, in the first aspect, the bag is fastened using a clip, a band, or a string. In the invention described in claim 3, claim 1 or 2
The invention described above is characterized in that the inner bag is filled with a gas or a liquid, and the outer bag is filled with a gas or a liquid.

According to the invention described in claim 4, the contents are put into the inner bag of the double bag having a sufficient air residual space formed between the inner bag and the outer bag, and the inner bag and the outer bag are sealed. It is characterized in that a part of the bag is tightened from outside using a tightening tool.

[0008]

[Action] Put the contents in the inner bag of the double-layered bag,
Fill the air between the inner bag and the outer bag and close the mouth of the bag. Thereafter, a part of the bag is tightened with a clip, a band, a string or the like, thereby reducing the volume of the bag and increasing the pressure of the air layer between the inner bag and the outer bag. As a result, the inner bag is held in a hollow state by the high-pressure air, and does not directly receive the impact even when it receives an impact such as a fall.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail with reference to FIG. FIG. 1A shows a double bag 1 composed of an inner bag 2 and an outer bag 3, which is made of a plastic laminated film. A glass 5 is put in the inner bag 2 side of the double bag 1 as shown in (b), and the double bag 1 is placed as shown in (c).
Is heat-sealed 4 so that the inner bag 2 and the outer bag 3
Seal. Next, as shown in (d), the double bag 1 is glued from the outside using the clip 6 to form the inner bag 2 and the outer bag 3.
Increase the internal pressure of the. The form and material of the bag may be any as long as the internal pressure does not escape.

[0010]

As described above, according to the present invention, unlike a conventional cushioning material or a molding tray, a certain bag size can be applied to many objects regardless of the shape of a product, and a case for an exterior. Since it is not necessary, the volume of resources to be disposed after the product is taken out can be significantly reduced. In addition, the state of the contents can always be confirmed by using a transparent bag.
