Description

[Detailed Description of the Invention] [Industry] Second Field of Application] The present invention relates to a buffer cage in a box for storing and transporting articles, and in particular, to protect the articles from damage due to vibrations, external forces, etc. during transportation. This relates to a cushioning material for inside a box that prevents this.

[Conventional technology] Conventionally, when packing crystal products in boxes, a buffer material such as cardboard or foam is placed between the product and the box to prevent the product from shifting due to vibration during transportation or damage due to external forces. It is interposed and protected. When making the above-mentioned cushioning paper from foam such as styrofoam, a mold is used to mold it to match the product shape and box shape, but depending on the number of products produced, the depreciation cost of the mold increases and the packaging cost increases. 1. was expensive. Furthermore, when the cushioning material is made by cutting or pasting cardboard, it is often time-consuming to assemble the cushioning material.

For this reason, for example, a technique disclosed in Japanese Utility Model Publication No. 63-612 has been proposed. This involves folding a sheet of cardboard or cardboard to assemble an isosceles triangular cylinder, and forming a cutout window for inserting a part of the product corner on the cylinder surface corresponding to the base of the isosceles triangle. , two cylinder surfaces of equal sides are overlapped to form a buffer shrine, which is installed at the four corners of a rectangular parallelepiped box. As a result, the product is supported at four locations around its peripheral corners and is housed and protected in the box. The buffer magazine is easy to produce and assemble because it is only necessary to cut out a sheet of cardboard or cardboard to form predetermined folding lines and cutouts.

[Problem to be solved by the invention] However, the above-mentioned Utility Model Publication No. 6 3-6 1. The technology in Publication No. 2 increases the protection of the product by doubling the two layers that come into contact with a part of the corner of the product, but in the case of products that are vulnerable to impact, the thickness of the cushioning material There are many cases where the required buffering effect cannot be obtained due to insufficient amount.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a buffer for inside a box that improves the buffering capacity between the article and the box and can be easily and inexpensively produced.

1,000 Steps to Solve Problem 1" The in-box buffer according to the present invention has a structure in which the surface that contacts the articles stored in the box is molded on the outside, and the surface molded on the outside is formed on the inside. Then, the buffer main body, which is placed in the four corners of the box 1 and comes into contact with at least 8 places of the items stored in the box, is moved through the shape retaining means and is placed in the 4 corners of the box.
The shape of the wooden body is maintained at the four corners of the box.

[Function] In the present invention, the shape of the buffer body is changed by passing through a thousand stages of shape retention, and the shape of the buffer body is maintained at the d corner of the packaging box, and the surface that comes into contact with the article stored in the packaging box is used to maintain the shape of the buffer body. Because the item is brought into contact with 8 points of the item stored in the box, if shock is applied due to vibration or external force during transportation, the impact is alleviated by the bullet t'L of the buffer body, and the item is protected.

[Example] Examples of the present invention will be described below.
