Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a corner pad that protects against a corner.
[0002]
[Prior art]
As shown in the multi-corrugated cardboard cushioning material of Japanese Utility Model Application No. 04-094527, the conventional square pad is bonded to the edge of the punched portion 5 punched into a V shape and fixed in a folded state. It was a structure.
[0003]
[Problems to be solved by the invention]
In the conventional technique, since the bending state is fixed with glue, it takes time and labor for bonding. It is an object of the present invention to provide a square pad that can fix a bent state without bonding.
[0004]
[Means for Solving the Problems]
The pad was bent and bent by shrinking the inner side of the corrugated sheet wave width (width perpendicular to the wave amplitude) with the same wave line (wave ridge line and valley line). Fix by inserting the pad into the frame.

DETAILED DESCRIPTION OF THE INVENTION
The product of the present invention is manufactured using cardboard or corrugated paper as the material, and the positional relationship such as the front back (front / rear), top / bottom (top / bottom) and left / right is displayed with reference to the front (pad insertion direction) in the assembled state. The folding direction described in the mountain or valley fold is displayed with reference to the outside.
[0006]
In FIG. 1 of the front perspective view before fitting, the pad 1 may be a foamed artificial resin. However, a pad having a thickness increased by laminating (bonding) corrugated paper is desirable. It may be a corrugated board (corrugated cardboard with both sides of the corrugated sheet), but it is preferably a single stage (corrugated cardboard with a corrugated sheet attached to one side of the corrugated sheet). It is desirable to form the pad 1 by interposing the flat plate 4 on the plate, the thickness of the pad 1 being the laminating direction, the width being the wave line direction of the wave plate 3, the length being the direction perpendicular to the wave line, and the same wave The pad 1 bends inward by shrinking the wave width of the streaks inside, and the bend angle is not limited, but it is desirable that it be a right angle. If the inner cut surface to bend is flat, the bent inner angle is rounded, If you want to make it square, insert a right-angled V-shaped groove into the inner corner. The number of points to be bent is an angle (L-shape) if it is one place, and a channel (U-shape or U-shape) if it is two places. The channel-type central wall is curved even if it is flat. The bent state of the pad 1 is fixed by fitting the bent pad 1 into the frame 2, and the frame 2 uses both cardboard and thin steps, and the shape of the frame 2 is like a partition frame. If the pad 1 is an angle type, the back plate 6 extended to the back edge of the bottom plate 5 is folded at a right angle, and both side edges of the bottom plate 5 and the back plate 6 are formed in a right triangle shape. When the pad 1 is a channel type, the top plate extended to the top edge of the back plate 6 is folded at a right angle in the front direction, and both side edges of the bottom plate 5, the back plate 6 and the top plate are formed. Are connected to each other by a rectangular side plate, and the left and right widths of the bottom plate 5, the back plate 6 and the top plate are the same as the thickness of the pad 1, so that the side plate 7 The bottom plate 5, the back plate 6, and the top plate serve to block the pad 1 from returning from the bent state to the original straight state. 2. Put the item stored in 2 on the corner of the package and store it in the outer box to complete the packaging.

Assembling process of the frame In FIG. 2 of the rear perspective view, if the structure is described taking an angle type pad storage frame (angle frame) as an example, the side plate 7 may be a single layer. The inner plate 8 and the outer plate 9 may be bonded to each other with glue, but it is desirable to have a structure in which they are inserted and fixed. Then, the insertion piece 10 is extended over the back edge of the outer side plate 9 via a mountain fold line, and the boundary mountain fold between the inner side plate 8 and the back plate 6 that overlaps the insertion piece 10 when the outer side plate 9 is folded up and closed. By inserting the insertion groove 11 on the wire and inserting the insertion piece 10 into the insertion groove 11, the overlapping state of the side plates 7 is fixed. Even if the shape of the insertion piece 10 is semicircular, both corners are rounded. It may be a rectangular shape, and is provided with protrusions to prevent it from coming out at both corners of the base fold line 13 It may be.
[0008]
In FIG. 3 of the development plan view of the frame, only in FIG. 3, the positional relationship between the top and the bottom will be described in accordance with the illustration, and if the development view of the angle frame is explained, a mountain fold line is formed above the bottom plate 5. The inner plate 8 is extended through the mountain fold line on both sides of the back plate 6 that extends through the bottom back fold line 12, and the top of the outer plate 9 that extends through the mountain fold line at both sides of the bottom plate 5. It is desirable to extend the insertion piece 10 from a partial portion of the edge via a base folding line 13 that is a mountain fold line, and the insertion piece 10 is preferably formed by partially cutting the lower region of the inner plate 8. On the mountain fold line on both sides of the plate 6, a portion overlapping the base fold line 13 of the insertion piece 10 is cut at the time of assembly to open the insertion groove 11, and the insertion groove 11 is elongated vertically even if it is a rectangular elongated hole vertically. A U-shaped notch may be used, and the four inner and outer side plates 9 are connected to each end of the bottom folding line 12. Since the corner portion of the corner is directed, the entire unfolded state has a shape close to a square rotated by 45 degrees, so that the efficiency of paper removal is good, and the insertion piece 10 is inserted into the insertion groove 11 and assembled. This eliminates the need for bonding with glue.

【The invention's effect】
As the wave width of the corrugated sheet is reduced, the pad bends in the direction of the corrugated sheet. Fixed the bending state of the pad with the friction that pressed down the thickness direction of the pad, and the bottom plate, back plate and top plate play the role of blocking the bending state, so the bending state is glued like conventional technology There is no need to fix with.
