A gas can be injected into the inside. By changing the shape of the bag filled with gas into a plurality of connected shapes by miniaturizing the gas chamber into which the gas enters, various structures such as a single-layer structure, a multilayer structure, and an odd-shaped structure can be used for the structure of the buffer body composed of the bag. It becomes possible.

By injecting a gas such as air or nitrogen gas into a bag constituting a buffer provided on the inner surface of the packaging box, the bag expands to form a buffer. Therefore, packaging that does not use a cushioning material such as styrene foam, which has been conventionally used, becomes possible. When not in use, the gas only needs to be discharged from the bag. Therefore, when not in use, such a buffer does not intervene, resulting in the effect of resource saving, physical distribution and space saving. In addition, by reducing the size of the gas chamber into which the gas enters and making it a plurality of connections, the bag can be made into a single-layer structure, multi-layer structure, or odd-shaped structure of the buffer. Unconstrained,
