Abstract

PURPOSE:To keep a load of packed objects from collapsing during transportation and suitably cope with the packing in transportation of many different kinds of objects with an effect to reduce the cost by fitting together a mortise and tenon by interposing a connecting plate in an arrangement of a cushioning material for packing. CONSTITUTION:An assembly of a cushioning material for packing is formed by passing tenons 16-18 on each of two pieces of the cushioning material for packing 12, 12 through joint holes 23-25 and 26-28 formed at two ends in a connecting plate 22. Next, an object for packing is mounted with each of its four bottom corners upon a middle board 15 of one of the cushioning materials 12 and with the troughs of two assemblies of the cushioning material set mutually opposite and the assemblies of the cushioning material are pressed against the object for packing to form their combination. Such combinations are laid one above another in a pile. In piling them up the tenons 16-18 projecting from a combination laid under are fitted into corresponding mortises 19-21 formed in the lower part of the cushioning material 12 of the combination laid above. Finally the combinations laid in a pile are roped up and down at the front and rear ends.

[0004]

According to the conventional cushioning wrapping material constructed as described above, there is a risk that the packaged article may be displaced due to a slight impact during cargo handling or transportation, causing collapse of the article. There is. Further, it is necessary to manufacture the cushioning wrapping material for the products to be packaged with different thicknesses according to the size of each product, which is costly. Further, since the cushioning wrapping material is made of foamed styrene, static electricity is liable to be generated on the surface and dust is likely to adhere to the cushioning wrapping material. In addition, it has weak strength, is easily broken, and has a problem in disposal after use, which is insufficient to protect the end of a heavy packaged object such as a lighting fixture.

The present invention has been made in order to solve the above-mentioned problems, and does not cause a load collapse when transporting a packaged object, and can sufficiently cope with the transportation of many types of packaged objects. The purpose of the present invention is to obtain a cushioning packaging material assembly that can reduce the amount of dust, prevent dust from adhering, and reuse it even after use.

Further, even when the width dimension of the packaged body is different, the width dimension difference of the flat plate body can be dealt with by changing the dimension of the connection plate in the longitudinal direction in accordance with the width dimension of the packaged body.

Further, since the cushioning wrapping material is made of polypropylene, it has a superior cushioning property as compared with the cushioning material made of foamed styrene or the like. Therefore, the packaged article is not damaged by shock or vibration during transportation, and is also protected from static electricity. Dust adhesion is prevented. Furthermore, after the combination is used, the connection plate and the cushioning packaging material of the cushioning packaging material assembly can be individually separated, so that they can be collected compactly and reused.
