Cushion material for packaging product therein and suspension air-packing method using same

Abstract

A cushion material for packaging a product is capable of absorbing shocks and impacts and being used for various types of product in a multipurpose manner. A large volume of the cushion materials can be produced through an automatic production process at a low cost. A suspension air-packing method using the cushion material packs the product in a mid-hanging manner. The cushion material includes at least two flexible films facing one another and the edges of the two films are heat-sealed, a bag portion for holding the product therein, and a cushion portion established on the outer periphery of the bag portion which will be inflated by the air when the compressed air.

Description

FIELD OF THE INVENTION [0001] The present invention relates to a cushion material for packing a product by using air as a buffer against shocks or other impacts and a suspension air-packing method that uses the cushion material for the product to be protected. BACKGROUND OF THE INVENTION [0002] Traditionally, cushion materials based on form plastic such as foaming polystyrene have been used as a shock absorber during the physical distribution of consumer products such as electronic devices, personal computers, precision instruments, ceramic ware and the like. Recently, however, there has been an increase in the usage of paper-based cushion material since the foam plastic increases the environmental load. [0003] For example, Japanese Laid-Open Publication No. 7-315366 discloses such a paper-based cushion material. In this patent publication, a main body of the cushion material and a reinforced wall that will be established therein are formed in a developed shape (flat plate manner) f...

AI Technical Summary

Benefits of technology

[0011] It is, therefore, an object of the present invention to provide a cushion material for packing a product therein which is capable of being used repeatedly while absorbing large shocks and impacts.

[0012] It is another object of the present invention to provide a cushion material for packing various products of different shapes and sizes where the cushion material is easy to manufacture and use.

[0017] Further, in the above noted cushion material of the present invention, the opening for injecting the air therethrough prevents the injected air from reverse flowing by having a check valve comprising a labyrinth construction or a narrow pathway. Further, in the above noted cushion material of the present invention, the opening for injecting the air therethrough prevents the injected air from reverse flowing by having a check valve.

[0021] According to the cushion material and the suspension air packing method using the cushion material of the present invention, the product to be protected such as a precision instrument, a recording medium, a laptop compute, etc. is packed in the mid-air in a stable manner. The cushion material and suspension air packing method of the present invention can effectively absorb the shocks and vibrations applied to the product during the product distribution process by flexibly hanging the bag portion in the mid-air and inflating the cushion material by the compressed air. A large number of the cushion materials of the present invention can be piled on one another without being inflated by the air and easily stored in a relatively small storage space and easily transported at low cost.

Problems solved by technology

Recently, however, there has been an increase in the usage of paper-based cushion material since the foam plastic increases the environmental load.

However, in the cushion material disclosed by the patent publication, since the holders and the support members are respectively formed by one piece of the corrugated board, the durability of the protruding piece for supporting the product to be packaged and the durability of the two sides of the holders for supporting the support members are low.

Thus, once these portions are suffered from an impact, deformation or damage will occur on the cushion material, which significantly lowers the resistance to another impact.

Further, there is another problem where other products cannot be accommodated since there is a limit to the size and shape of the product that can be packaged.

However, there are disadvantages in that the manufacturing process is complicated, a relatively large space is required for storing the cushion materials, and disposal of the cushion material is not easy.
