JPH1159737A - Double-angular pad without useless use of paper - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a double-angular pad which can be made without useless use of paper. SOLUTION: Side walls 5 are extended through side-folding lines 4 at both sides of the bottom wall 1 and the rear wall 3 partitioned by the bottom and rear-folding lines 2, and the side-folding lines 4 and the bottom and rear-folding lines 2 are bent to form valleys respectively to mutually stick the superposing side walls 5 and the inner plate 6 is stuck on the inside of the bottom wall 1 and the rear wall 3 to form a double-structure as the whole. Since the unfolded shape of the whole body is laterally long rectangular, useless use of paper can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double corner pad.

[0002]

2. Description of the Related Art A conventional double-angled corner pad is a bottom wall of an L-shaped pad which is obtained by winding a single corrugated cardboard in multiple layers and stacking them in an L-shaped mold in a dry state, followed by drying. A double-sided pad was formed by punching two places in a V-shape and bonding the edges punched out in the V-shape.

[0003]

In the prior art, the necessity of punching into a V-shape causes cuts and waste of material. The present invention aims at solving the problems of the prior art.

[0004]

A back wall extends at a back edge of the bottom wall through a bottom back folding line, and a side wall extends at both sides of the bottom wall and the back wall through a side folding line. By valley folding the bottom back fold line, the overlapping side walls are bonded and bonded, and the inner plate is bonded and bonded to the inner surface of the bottom wall and the back wall, so that the whole has a double structure, Since the entire developed shape is rectangular, there is no waste in paper removal.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention is based on a perspective view shown in the process of manufacturing and assembling a double-faced corrugated cardboard as a raw material. A back wall 3 having the same shape as the bottom wall 1 is extended through the fold line 2, and the bottom wall 1 and the back wall 3 may be square, and a side fold line 4 which is a valley fold line is formed on both sides of both walls. The square side wall 5 is extended through the outer plate 7 and the object constituted by
The side fold line 4 is valley-folded, and the bottom back fold line 2 is valley-folded at a right angle. Is to bond an inner plate 6 bent into an L shape to the inside of the bottom wall 1 and the back wall 3. The inner plate 6 is not only a plate bent into an L shape but also two sheets separated at a bent portion. The developed shape of the outer plate 7 may be rectangular, and the vertical width of the inner plate is substantially the same as the vertical width of the bottom wall and the back wall. Since the inner plates can be arranged with the same vertical width, the entire paper removal shape is a horizontally long rectangle, and the full width of the original sheet can be used effectively.

In FIG. 2 which is a perspective view showing a completed state, the side walls are originally double-structured because they are overlapped and bonded together. By bonding and bonding the plate 6, all surfaces of the double-sided pad form a double structure.

[0007]

According to the present invention, the developed shape of the outer plate is a horizontally long rectangle, and if the paper is taken out with the inner plate arranged next to the outer plate, the vertical widths of the outer plate and the inner plate are substantially the same. Since the full width of the original sheet can be effectively used, there is no waste of paper removal, and if the side walls are bonded and bonded, the outer plate becomes a double-sided pad shape and the inner plate 6
By gluing the paper inside, all surfaces have a double structure.

Claims (1)

[Claims] 1. A bottom back folding line 2 which is a valley folding line at a back edge of the bottom wall 1.
The back wall 3 is extended through the bottom wall 1 and the side wall 5 extended through the side fold line 4 which is a valley fold line on both sides of the bottom wall 1 and the back wall 3 to fold the bottom back fold line 2 into valleys. The side walls 5 overlapping with each other are bonded and bonded to form a diagonal pad shape, and the inner plate 6 is bonded and bonded to the inner surfaces of the bottom wall 1 and the back wall 3 so that all surfaces have a double structure. Double-sided pad for paper removal without waste.
