Abstract

PROBLEM TO BE SOLVED: To form a folding-over part freely on a location of product to be protected and attain a shock absorbing action corresponding to a degree of necessity under setting of an appropriate shock absorbing distance by a method wherein a blank material of a cardboard sheet with some slits therein punched out to a predetermined shape is overlapped from each other at the slits to form a casing. SOLUTION: An upper folding flap 42 is folded over an upper flap 40 at a slit section 28 and the upper flap 40 is bent at a right angle against an upper surface plate 14 at a slit section 26. The upper folding flaps 45, 44, 43 are folded in sequence and overlapped on the upper flap 41 and then they are folded at a right angle against the upper surface plate 14 at a slit section 27. In addition, a lower part flap 40' and lower folding flaps 42', 43', 44' and 45' are also similarly folded. A projected portion of a product is protected under three times of shock absorbing distances by a cardboard in which the cardboard is folded by three sheets of these upper flap 41, upper folding flaps 43, 44, 45, a lower flap 41' and lower folding flaps 43', 44' and 45'.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cushioning material made of corrugated cardboard for storing electric parts such as a timer and a relay switch, and for preventing a product from being damaged by external impact or vibration during storage or transportation. It is about.

[0002]

2. Description of the Related Art Conventionally, when packing electrical parts such as timers and relay switches, in order to prevent them from being damaged by external shocks or vibrations during storage or transportation, it is necessary to use a styrofoam. It was packed using cushioning material. However, in recent years, with the increasing protection of the global environment and the protection of resources, it is difficult to easily recycle and use styrofoam cushioning materials, and there is no choice but to incinerate and dispose of them. Therefore, their use tends to be suppressed.

[0003] On the other hand, corrugated cardboard made of polyethylene or a natural material has been reviewed as a cushioning material. In particular, paper cardboard has been reviewed, especially paper cardboard with a reinforced core structure,
For example, A-stage, B-stage, AB-stage and the like have been used as cushioning materials.

As a cushioning material made of cardboard made of paper,
For example, Japanese Unexamined Utility Model Application Publication No. Hei 4-124463 and Japanese Unexamined Patent Application Publication No. Hei 7-291360 include those described in Japanese Unexamined Utility Model Publication No. Hei 4-124463. With a configuration provided with one notch, the corner of a product to be packed is mainly protected. Further, Japanese Unexamined Patent Publication No. 7-291360 discloses that various types of products are reduced in the number of types of packing cases by using shock absorbers having a simple structure, and the entire product is protected. Although there are products that can be used with products, there are too rough packing for products such as precision electrical components such as instrument panels and knobs that are exposed and integrated circuits are built in. It is clearer than looking at fire that it cannot prevent damage from external shocks or vibrations during or during transportation.

[0005]

SUMMARY OF THE INVENTION Accordingly, the present invention provides a method for protecting a portion of a product such as a precision electrical component such as an instrument panel or a knob which is exposed and has an integrated circuit built therein, where the product should be protected. An object of the present invention is to provide a cushioning material that can easily set a buffering distance of a part to be protected of the product so that the cushioning function can be effectively exerted.

[0006]

The inventor of the present invention has conducted various studies to solve the above problems, and as a result, claim 1 has been obtained.
The cushioning material according to the invention described in the above is a cushioning material made of cardboard for storing a product having a substantially rectangular parallelepiped shape. Is provided, and the corrugated cardboard provided with the cutout portion is cut into a predetermined shape to form a blank, and the blank is folded at the cutout portion, or is folded and folded to form a housing. A folded portion is formed by folding at the cut portion. With such a configuration, it is possible to easily form a housing by simply folding or folding a blank made of one sheet at the cut portion, thereby protecting the entire product. In addition, a folded portion can be freely provided at a portion of the product to be protected, and the number of folded portions can be freely set, so that a buffering action according to the necessity of the portion of the product to be protected can be obtained. Can be easily set.

According to a second aspect of the present invention, in the cushioning material according to the first aspect, the housing includes two opposing surfaces of the housing and one surface connected to the two opposing surfaces of the housing. It is characterized in that the cross section that is not present is substantially U-shaped. With such a configuration, the product can be protected with less cushioning material, and the cost of the cushioning material can be reduced.

[0008] The invention described in claim 3 is based on claim 1,
3. The cushioning material according to claim 2, wherein a cutout having a predetermined shape is formed at a predetermined position of the cardboard forming the surface of the housing. With such a configuration, the projecting portion having a predetermined shape included in the product can be stored in a cutout portion having a predetermined shape formed at a predetermined portion of the cardboard. While it can be protected against, the product can be secured against movement during storage or transport.

According to a fourth aspect of the present invention, in the cushioning material according to the first aspect, the cardboard is made of paper. Such a configuration leads to protection of the global environment and protection of resources.
