Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an insertion pad that can be inserted into both sides and top and bottom of an object to be packed.
[0002]
[Prior art]
The conventional insertion pad is a V-shaped penetrating through the side wall of a product made of foamed polystyrene or a laminated cardboard ball and folded in a U-shape with two fold lines parallel to the longitudinal direction. By punching the punched portion and bonding the edges of the V-shaped punched portion, the floor board was bent to form a fitting pad.
[0003]
[Problems to be solved by the invention]
Styrofoam is a man-made resin, so there is a problem of emitting toxic gas at the time of incineration, and a material that punches out the V-shaped punched part produces a V-shaped piece, so the material is effective. There was a problem that it could not be used. The present invention aims to solve the problems of the prior art.
[0004]
[Means for Solving the Problems]
In order to achieve the above purpose, corrugated paper is used as a material, side plates extending on both sides of the back plate are folded to the front to form a bone plate, and the U plate is bonded to the top and bottom of the side plate. The opening is prevented from returning to the original, and a back laminate is bonded to the back surface of the back plate to form a fitting pad.
[0005]
DETAILED DESCRIPTION OF THE INVENTION
The bone plate uses double-sided corrugated cardboard as the material, and the laminated body is formed by stacking single-sided cardboard in multiple layers. The positional relationship in the description is based on the assembly direction as the front direction.
[0006]
The embodiment of the invention will be described with reference to the drawings. In FIG. 1 of a perspective view showing a state in which the laminated body is separated, the structure of the bone plate body 4 is formed by folding lines on both sides of the back plate 1. The side plate 2 extending through the front plate is folded at a right angle in the front direction, and a folding reinforcing piece 3 is extended to the front edge of the side plate 2 through a fold line so as to open outward. The vertical dimension of the back plate 1 is shorter than that of the side plate 2. It is preferable to reduce the vertical dimension of the back plate 1 to reduce the material of the back laminate 6 to be attached to the back surface of the back plate 1, and with the side plate 2 folded in front, The U-shaped laminated body 5 is adhered and attached in a state of covering the top and bottom of the side plate 2.
[0007]
In FIG. 2 of the perspective view shown with the laminated body attached, the side plate 2 is attached to the top plate of the back plate 2 with the U-hour laminated body 5 covered with the side plate 2 folded forward. The side plate 2 is reinforced by folding the fold reinforcing piece 3 outward, and is strong against pressure from the top and bottom.
[0008]
In FIG. 3 of the perspective view showing the state in which the storage item is inserted, the insertion pads 7 are provided in pairs because of the necessity to be inserted on both sides of the storage item 8, but are not shown in the figure. Complete the packaging in a box.
[0009]
【The invention's effect】
Since the material is corrugated cardboard using recycled paper, there is no problem at the time of incineration, and since the U plate laminate and the back laminate are bonded using the bone plate as an aggregate, it does not have a V-shaped punched portion. Therefore, since the vertical dimension of the back plate is shortened without taking out a piece, it is possible to reduce the amount of the back laminate laminated on the back plate, and the side plate 2 can be reinforced by folding the folding reinforcing piece. it can.
