However, one air injection device (5) and one check valve (6) are provided.

The packaging box equipped with the air bag of the present invention configured as described above is mainly used for packaging a package that may be damaged, and for example, a package (8) such as a video will be packaged. As shown in FIGS. 2 and 3, when the left and right paperboards (1) are combined with each other, the package (8) is put therein and air is injected through the left and right air injecting devices (5). The injected air is blown into the left and right air bag portions (2 ') (2' ') (2' '') (2 '' '') through the check valve (6) and the air bag is inflated. . At this time, since the folding line (1 ') is the window hole (4), there is no resistance to bending, and therefore the bent shape is maintained as it is, and the air blown into the air expands. The bag can cover the shape of the package (8). A part of it is adhered to the paperboard (1) by the adhesive section (7). The air bag bonded to the paperboard (1) expands as if it were a balloon, and the position of the air bag does not fluctuate even if an external shock is applied during the transportation of the package.

When the air injected into the air bag is removed after use, the air bag becomes a flat plate shape and adheres to the paperboard (1) at the adhesive portion (7). Therefore, when the paperboard (1) is folded. The air bag is also folded into a flat plate shape, and its volume can be made extremely small.

When the air blown into the air bladder is to be removed, a pipe is inserted into the hole of the air injecting device (5), and the tip of the pipe penetrates the check valve (6). The air in the bag can be easily discharged.

Further, when the air injecting device (6) is provided, when it is attempted to inject air into two air bags formed on the paperboard (1) at the same time, heat is applied to the central portion of the check valve (6). By forming the crimping wire (3) and forming the two check valves (6), it is possible to quickly inject air.

As shown in FIG. 5, a large number of air bags (2 ′) (2 ″) (2 ′ ″) are formed, and a large number of check valves (6a) (6b) (6c) are formed. If an air bag (2), which is installed at the entrance of each air bag part and that injects air from one air injection device (6) in a chain, is attached to the inner surface of the paperboard (1) of the packaging box, Each of the air bags (2 '), (2' '), (2' '') in the state of being injected is independent as an air bag, and one air bag is ruptured by an external impact. Also, the air will not escape from the remaining air bladder, and the state as it is will be maintained.

However, the air in the air bladder (2 ') only escapes, and the remaining check valves (6b) and (6c) remain the same, so the air is not released from the air bladder (2' ') (2' ''). It does not fall out and can be maintained as it is. Even if the check valves (6b) and (6c) are damaged, the air will not escape from the bladder (2).

Further, as shown in FIGS. 8 to 11, a paperboard (1) having a folding line (1 ′) and an air bag (2) adhered to the inner surface thereof is placed inside an existing packaging box. By inserting and making a double box, the package (8) can be safely packaged. As shown in FIG. 9, six bonding surfaces (2a) (2b) (2c) (2d) (2e) having a large number of thermocompression bonding wires (3a) (3b) (3c) in one air bag (2). ) When the air bag is filled with the package (8) and then air is injected into the air bag (2) composed of (2f), the package (8) is retained as if it were in a polystyrene foam product. As shown in Fig. 11, five bonding surfaces (2a) (2b) are formed by using many thermocompression bonding wires (3) on one air bag (2) as shown in Fig. 11. After forming (2c), (2d) and (2e) and inserting into one side or left and right sides of the packaging box, when injecting air into the air bag (2), it acts on the side of the package (8). The effect of buffering the shock works. It should be noted that the above-described air injection from the air injecting device (5) to the air bag (2) can be automated, and thus automatic packaging is also possible by making the position where the air bag is adhered constant. Is.

[Effect of device]

 As described above, according to the present invention, a plurality of air bags that are bounded by thermocompression bonding lines are formed on each surface of a paperboard having folding lines, and an air injecting device having a plurality of check valves is provided on the air bags. Since the air bag is adhered, when it is stored before or after use, if the air bag is evacuated, the air bag will have the same shape as the paperboard and the volume will be extremely small. It is convenient for transportation and storage, and when packing an object, simply put the package in a packaging box and then inject air into the air bag, and the air bag will expand and the package will be surrounded. Since it is wrapped, the cushioning force is generated against impact and the package can be protected. At this time, since the air bag is adhered to the paperboard of the packaging box by the adhesive portion, there is no risk of the air bag being detached or moved by an impact from outside during transportation. There is also an advantage that automatic packaging is possible by keeping the position where the air bag is bonded constant.
