JPH07206046A - Packing bag - Google Patents

Abstract

PURPOSE:To provide a packing bag that can be used for packing and transporting articles to be carried that are easily breakable. CONSTITUTION:A sealed up bag body 1, equipped with a check valve 2, is folded double, and internal faces 3, 4 on the right and the left are joined together and two split bag bodies 11, 12 with a space 13 for housing an article to be carried provided in between are formed integrally. Thereby, a case for surrounding the bag becomes unnecessary.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging bag suitable for carrying easily fragile articles such as parcels such as glass.

[0002]

2. Description of the Related Art Conventionally, there is an idea of packing a bag using an air bag, but all the conventional ones require a box for receiving the air bag.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to provide a packaging bag which can be used very easily and does not require the use of a box surrounding the bag.

[0004]

The means of the present invention are as follows. A check valve communicating inside is attached to a sealed bag made of an impermeable material or a multi-layered impermeable material with a protective film on the entire inner surface, and the sealed bag is folded in half from the middle,
The left and right side edges are adhered to each other to form two divided bags which form a storage space for a package surrounded by multiple layers, and the divided bags themselves are joined along an intermediate fold of the closed bag. A packing bag that has a crimping wire portion that forms the bottom between both split bag bodies.

[0005]

When the goods to be transported G are stored in the accommodating space 13 and air is pressure-fed from the check valve 2 to the divided bag bodies 11 and 12, the divided bag bodies 1 are separated.
1 and 12 expand and cover the periphery of the article in the accommodation space 13 with an air film. Carry as it is.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIGS. 3 and 4, reference numeral 1 is a closed bag body, and a check valve 2 communicating with the inside is inserted at one end edge thereof, and a protective film 15 of a mirror sheet, paper or resin sheet is applied to the entire inner surface. This hermetically sealed bag body 1 is folded in two from an intermediate fold 10 and the left and right edges thereof are subjected to thermocompression bonding 3 and 4 as shown in FIG. 1 to be divided into two divided bag bodies 11 and 12 shown in FIG. At the time, along the intermediate fold line 10, crimping lines 5 and 6 are applied to the bottom portions of the respective divided bag bodies 11 and 12, and these are joined to each other to form the divided bag bodies 1.
An accommodation space 13 for transporting goods, whose bottom is the crimping wires 5 and 6, is formed between the terminals 1 and 12. Incidentally, in order to maintain the strength of the inside of the closed bag in place of the protective film 15, there may be used a multi-layered impermeable material, and a protective film such as kraft paper may be provided on the outside of the closed bag.

[0007]

[Effects] According to the present invention, a transported article is stored in the storage space,
If air is pressure-fed from the check valve and the divided bag body is expanded, the transported material can be reliably protected by air and wrapped. Further, since the inner surface is protected, it is possible to prevent the bag from being damaged or the air leaking due to the protrusion of the package.
