JP4489533B2 - Packing shock absorber - Google Patents

Description

  The present invention relates to a shock absorber for packaging, and more particularly to a shock absorber using a shock absorber for packaging that is assembled by folding cardboard.

  When various kinds of articles are packed and used for distribution, the article may be damaged due to an impact by an external force in the distribution stage. Therefore, conventionally, when various kinds of articles are used for distribution, these articles are stored in a packaging box. Then, a foamed polystyrene resin buffer is disposed in the gap between the packaging box and the article, and the shock from the outside is absorbed by the buffer, thereby protecting the article from the impact.

  A conventional buffer using such a foamed polystyrene resin does not have a natural disintegration property when discarded after use, and therefore remains as it is for a long period of time, causing waste pollution. If incinerated, the foamed polystyrene buffer will generate high heat and damage the furnace, or it will emit black smoke and cause air pollution. Due to such environmental problems, the use of a foamed polystyrene resin buffer tends to be limited.

  Therefore, it has been proposed to assemble a shock absorber using corrugated cardboard having a natural disintegrating property. Corrugated cardboard is made from cellulose, so even if it is discarded, it will eventually be decomposed by bacteria to become water and carbon dioxide, which will not cause environmental damage. In addition, it can be decomposed and regenerated with water and can be recycled, leading to effective use of resources.

  Accordingly, the inventors of the present application disclosed a corrugated cardboard having a cutting line partially connected by a connecting portion according to Japanese Patent Laid-Open Nos. 2001-6376, 2001-72134, 2001-72138, and the like. In the meantime, a shock absorber using a shock absorbing cushion that is alternately bent and joined in opposite directions is proposed.

If an article is to be completely surrounded by such a shock absorber, a large shock absorber is required, and the amount of corrugated cardboard constituting such a shock absorber is greatly increased. In addition, the portion that does not require the cushioning effect is protected by a buffer body in which the corrugated cardboard is folded and laminated, and there is a problem that the use of corrugated cardboard becomes unreasonable. Further, such a buffer has a drawback that the cost is increased as compared with a conventional foamed polystyrene resin buffer.
