Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cushioning material for packaging in which an article is wrapped and can be accommodated in an outer box such as a decorative box with a lowering hand.

[0002]

2. Description of the Related Art When articles are stored in a cardboard box or the like, in order to prevent the articles from being damaged, a block-shaped cushioning material made of foam is packed in required portions including corners of the box. It is general that it is.

[0003]

However, since such a cushioning material is a foamed molded article, it becomes large and unduly bulky to hold the stored articles, and a certain number of cushioning materials are separated. , It was extremely inconvenient to handle.

[0004] The present invention has been made in view of the above points, and its object is to provide a sheet material which has a cushioning property as a whole and can be assembled in a box shape so as to cover an article, and When the lid is closed, the bulging portion provided in the lid portion functions as a cushioning material, and the concave portion on the back side of the bulging portion can be used as a storage portion for small articles. To provide a cushioning material.

[0005]

In order to achieve the above object, the cushioning material for packaging according to the present invention is characterized in that a side plate is provided on each side of a rectangular bottom plate via a hinge portion. A sheet material that can be assembled into a box in which a lid plate is connected to the upper side of each of the two side plates via a hinge portion, and at least the lid plate of the sheet material protrudes toward the inner surface side of the lid plate. By forming a portion, a concave portion is provided on the outer surface side.

The lid plate is connected to the side plate via two parallel hinges so that the lid can be smoothly closed when the sheet material is assembled in a box shape. Is preferred.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the accompanying drawings. The sheet material 1 has side plates 4, 5, 6, 7 via hinge portions 3 on each side of a rectangular bottom plate 2, and is parallel to an upper side of one of the side plates 4, 5, 6, 7 among the side plates 4, 5, 6, 7. The cover plate 9 is connected to each other via the two hinge portions 8a and 8b. When the sheet material 1 is assembled in a box shape, the assembly is closed by the cover plate 9. Can be.

[0008] At least the lid plate 9 is provided with a bulging portion 11 for suppressing articles packed on the inner side which is the inner side when the sheet material 1 is assembled in a box shape, so that the rear side thereof is formed. A concave portion 12 is provided on a certain outer surface side. In the case shown in the figure, such bulges and recesses are provided on the side plates 4, 5, 6, 7
The bulging portion is denoted by reference numeral 13 and the recessed portion is denoted by reference numeral 14, and the shape of the bulging portions 11, 13 is determined by the form of the article to be accommodated and the allowable G value. One side of the cover plate 9 which is in contact with the upper side 5a of the side plate 5 at the time of assembling the sheet material 1 is formed as a finger hook 9a.

According to the above configuration, the present cushioning material can be packaged in a state of covering an article such as a video camera, and the packaging form is a box shape. Therefore, as shown in FIGS. Can be fitted and stored in an outer box 21 such as an assembled makeup box with a lowering hand. Then, when the cover plate 9 is closed as shown in FIG. 3, the recess 12 of the cover plate 9 can store accessories and the like of the article covered by the sheet material 1. In this case, the packaged article is favorably held by the bulging portions 11 and 13.

Further, since two hinge portions 8a and 8b are provided between the side plate 7 and the cover plate 9, these hinge portions 8a and 8b are attached to the cover plate 9 when the cover plate 9 is closed. The formed bulging portion 11 functions as an escape for avoiding a problem of contact with the article, and the cover plate 9 can be closed smoothly.

As the sheet material 1, a foamed or non-foamed resin sheet of polystyrene, polypropylene, polyethylene, or the like, or a multilayer sheet obtained by combining these sheets is used. Is preferably a foamed resin sheet. The bulging portion 11 (and the bulging portion 13) formed on the sheet material 1 is formed by vacuum forming, press forming, or the like. In the drawing, 22 is an inner lid piece of the outer box 21, 23 is an outer lid piece, 24 is an insertion piece for locking the outer lid piece 23, and 25 and 26 are lowering hands provided on the inner and outer lid pieces 22 and 23. Is a piece.

[0012]

The present invention is as described above, and the sheet material can be assembled in a box shape and can be wrapped around an article, and the package is fit into an outer box and stored. Therefore, the packaging state of the article is determined, and the article can be well protected by the presence of the bulging portion and, when the sheet material is a foamed resin sheet, its own cushioning property. Further, the concave portion of the lid plate can function as a storage portion for small articles, and the effect in use is further promoted. And, by having two hinge portions of the lid plate, the closing operation of the lid plate can be smoothly performed, and the handling is extremely convenient,
Its practical value is enormous.
