2. Description of the Related Art Conventionally, a bladder formed by feeding a gas or a liquid into an airtight container such as a soft rubber or plastic to expand its volume is easily formed by an impact from a projection from the outside. It is damaged, quickly reducing its overall volume and losing its original function.

[0003]

According to the present invention, a plurality of the above-mentioned sac-like bodies are connected to form a connected independent sac-like body, and even in the case of impact damage due to the above-mentioned projections, the volume of the entire sac-like body is increased by the diffusion of the fluid. An object of the present invention is to provide a non-reducing articulated bag with a check valve and a product using the same, for example, a tube pad for packing. That is, as the packing material, a packing chip material or a molded article using a lightweight plastic foam material such as styrofoam is generally widespread, but the conventional packing material as described above is
For heavy objects that require careful handling, the use of a dedicated molding material simplifies the packaging process and is more efficient, but as long as the quantity does not consolidate, the manufacturing cost of the packaging material itself will increase. There is a problem that it is expensive, and because it occupies a large amount of space when used as a packing material and when storing it, storage costs such as transportation costs and warehouse fees increase, which puts pressure on corporate profits. At the same time, it is becoming a major social problem, such as disposing of waste or incineration, in which case large costs must be paid from the viewpoint of environmental protection. The present invention has been made in order to solve the above-mentioned problems, and is suitable for resource saving by withstanding a high impact load during use and performing padding focusing on an optimal position for an article shape. It is also intended to provide low-cost packaging materials that can be stored in a minimum occupied volume.

[0005]

The connecting independent sac with a check valve, which is formed by connecting a plurality of sacs whose volume has been expanded by feeding gas into the bag body having the above-mentioned structure, is not limited to a shock caused by an external projection. Even if it breaks and gas evolves, the loss of volume is limited to the damaged local sac and only loses a portion of the original volume, not the entire articulated sac. Therefore, in the tube pad according to the application example of the connection independent sac-like body with the check valve, the sealed gas pressure is stably held by the check valve. It can be filled in between, or the article can be freely fixed to the packing container, especially after the tube pad is wound around the article, and the gas is supplied through the check valve to the tube. By adjusting the gas pressure while expanding the volume of the pad, the degree of fixing of the article to the packing container can be arbitrarily adjusted, and the minimum volume can be minimized by degassing and folding the gas when not in use. Can be reduced to
