2. Description of the Related Art A safety laminated glass is one in which an interlayer film made of plasticized polyvinyl butyral resin, polyvinyl acetal resin, or the like is interposed between two glass plates, which has high strength and should be damaged. Also, because it has excellent performance such as debris not scattering around,
Widely used as window glass for airplanes and buildings.

The interlayer film of this safety laminated glass is generally manufactured continuously by extrusion molding, wound on a core and shipped to the user in the form of a roll.

At the time of shipping, the moisture content of the intermediate film is kept constant, the deformation of the film due to the pressure between the rolls, which are heavy bodies, is prevented, and the intermediate layer partially formed with the colored layer is formed. In the case of a film, it is necessary to satisfy various conditions such as preventing discoloration of the colored layer, enabling low temperature storage and transportation to prevent adhesion between the films, and preventing foreign matter from entering. For this reason, conventionally, the roll body a has been packed in a box shape by using a packaging material as shown in FIG. 3 (the figure shows an example of packaging four roll bodies a). That is, the rolls a are placed one by one in an aluminum laminate bag b, which is placed on a pallet c.
Sequentially placed on the top through the lower positioning plate e, then the roll body a
Is surrounded by a rectangular body plate f, an upper positioning plate h, an upper lid g, and a top plate i are sequentially placed on the roll body a, and these packing materials c to i are bound by a binding band (not shown). Was there. The symbol k in the drawing indicates an engagement hole that engages with the end of the winding core of the roll body a.

Further, when only one roll is packed, the roll is housed in a corrugated fiber drum (not shown).

[0006]

However, in the above conventional packaging method, although it is possible to deliver the product to the user without deteriorating the quality of the intermediate film at the time of production, the bottom cover d and the vertical positioning are provided. Since a large amount of materials such as the plates e and h, the body plate f, the upper lid g, and the top plate i are used, not only the packing cost increases, but also time and labor are required for both packing and unpacking. was there.

The bottom cover d, the upper and lower positioning plates e and h, the body plate f, and the top cover g which occupy most of the above-mentioned packaging materials.
Is generally made of corrugated board, and the corrugated board is usually damaged by one-time use, and cannot be reused as a packing material for the interlayer film which does not want to be dirty. In particular, this problem is serious nowadays when the effective use of resources is being called for, and there is an urgent need to solve it.

Further, corrugated cardboard materials such as the bottom lid d which cannot be reused as packing materials for the interlayer film can be used only as recycled paper materials after all. However, after unpacking, these materials are collected once. There was a problem that it was necessary to store it and it was often difficult to secure a place for it.

Further, in the case of the fiber drum used for packing one roll body, since it is bulky, there is a problem that a lot of space is required for a storage place when it is not used.

The present invention has been made to solve these problems, and both packing and unpacking can be performed quickly and easily, and most of the packing materials can be reused. An object of the present invention is to provide a method for packing a roll body and a roll body packaged product obtained thereby.

[0011]

According to the method of packing a roll body of the present invention, the lower end of the standing roll body is fitted into the roll body receiving recess of the base having the roll body receiving recess formed on the upper surface. To the upper end of the roll body, a synthetic resin top plate having engaging means for engaging the winding core end portion of the roll body on the lower surface is mounted through the engaging means, and finally these top plate and roll body ,
The base and the pallet are bound by a binding means.

In the roll body package according to the present invention, the lower end of the roll body in the upright state is fitted into the roll body receiving recess on the upper surface of the base, while the lower surface is engaged with the winding core end portion of the roll body. A synthetic resin top plate having matching engaging means is mounted on the upper end of the roll body through the engaging means, and the top board, roll body and base are integrally bound by the binding means. Is.

Further, the base may be composed of a pallet and a base body made of synthetic resin placed on the pallet.

[0014]

Since the packing material in the present invention has only four bases (base body / pallet), top plate and binding means, the material cost can be significantly reduced as compared with the conventional one, and the packing and unpacking can be performed in a short time. And it can be done easily. Further, among these four materials, up to three of the base (base body / pallet) and the top plate can be reused, so that effective use of resources can be achieved.
