Abstract

(57) [Summary] [Purpose] To provide a packaging bag that can easily transport fragile cargo for safe transportation. [Structure] The sealed bag body (1) provided with a check valve (2) is folded in two, and the left and right sides of each are joined (3) and (4) to provide a storage space (13) for a transported article in the middle. Forming two divided bags (11) and (12).

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a packaging bag suitable for carrying parcels, particularly glass and other easily destructible items.

[0002]

[Prior art]

 Although there has been an idea of packing a bag using an air bag, all conventional ones require a box to receive the air bag.

[0003]

[Problems to be solved by the device]

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

[0004]

[Means for Solving the Problems]

 The means of the present invention are as follows.

A check valve communicating with the inside is attached to a tightly closed bag body made of an impermeable material or a multi-layered impermeable material having a protective film on the entire inner surface, and the sealed bag body is folded in half from the middle, The left and right side edges are adhered to each other so as to form two divided bags each having a space for accommodating a package surrounded by a protective film or multiple layers, and each divided bag along the middle fold of the sealed bag. A packaging bag provided with a crimping wire portion that joins together.

[0006]

[Action]

 When the goods to be transported G are stored in the storage space 13 and air is pressure-fed from the check valve 2 to the divided bag bodies 11 and 12, the divided bag bodies 11 and 12 are inflated, and the circumference of the articles in the storage space 13 is covered with an air film. U Carry as it is.

[0007]

Embodiment 1 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, and a protective film 5 of a mirror sheet, paper or resin sheet is applied to the entire inner surface. This hermetically sealed bag 1 is folded in two from the intermediate fold 10 and left and right edges thereof are heated and pressed as shown in FIG. 1 to be divided into two divided bags 11 and 12 shown in FIG. At that time, crimping lines 5 and 6 are provided along the intermediate fold 10 on the bottom portions of the respective divided bag bodies 11 and 12, and these are joined to each other to form the crimping lines 5 and 6 between the divided bag bodies 11 and 12. A storage space 13 for forming a bottom is formed. Instead of the protective film 5, multiple layers of impermeable material may be used to maintain the strength inside the closed bag.

[0008]

【effect】

 According to the present invention, when the goods to be transported are stored in the storage space, air is pumped from the check valve, and the divided bag body is inflated, the transportation can be reliably protected by the air and wrapped. Wear. Also, since the inner surface is protected, it is possible to prevent the bag from being damaged or causing air leakage due to the protrusion of the package.
