This invention relates to a corner protection member that prevents dangers such as storage.

[Prior Art] Conventionally, this type of corner protection member is made by filling a paper box A made of cardboard or the like with alternating pieces of recycled paper hardened into a plate shape and wood wool, as shown in FIG. It is known that the top cover 7 is made of a material and further has an X-shaped cut line 17 in the longitudinal direction thereof.

[Problems to be solved by the invention] In such conventional products, for example, when protecting the bonnet of a car, the cut line 1 provided on the top cover 7
7 and the curvature of the curved surface of the edge of the bonnet do not match, the edge inserted into the corner cut line 17 tends to wobble and shift position, causing the paper box to lose its shape and supporting the acute corner. It became unstable and was unsatisfactory as a protective member.

[Means for Solving the Problems] Therefore, the purpose of the present invention is to provide a protection member for acute corners of a plate-like member that solves the above problems. At the top of the front and rear side walls, upper lid pieces each having a locking piece extending from the tip thereof are connected, and at the upper part of each of the left and right side walls, overlapping lid pieces are installed, and at the bottom of each of the side walls, a top lid piece is installed. A paper box is formed with a bottom piece provided through the fold line, a cut groove having the required width and depth in the vertical direction is provided in the center of the overlapping lid piece, and the cut grooves are provided at both rear ends of the cut groove. A continuous score line is provided on each overlapping lid piece and the left and right side walls on the extension line of the cut groove, and continuous score lines are provided across the shoulders of the paper box, and each side wall is bent inward. Bend the top cover piece and the overlapping cover piece inward, and then insert the left and right ends of each of the locking pieces into the cut grooves so that they stand upright inside the paper box. A gap is formed in the center of the top cover by the groove, and a buffer member is loaded inside the paper box at a height slightly lower than the height of the paper box.

[Function] A plate-like member with curved edges is inserted into a gap of a required width provided on the top surface of the paper box, and the side edge of the plate-like member is aligned with the dividing line provided on the overlapping lid piece at one end edge of the paper box. The lower edge of the plate-like member faces into the paper box through the gap provided on the upper surface, and the part at a certain distance from the acute corner of the lower edge is overlapped with the other end of the paper box. Place it on the overlapping lid piece between the two cut lines provided on the lid piece. At this point, the height of the cushioning material loaded into the paper box is slightly lower than the height of the paper box, so the polymerized lid piece is locally dented, and the plate-shaped member does not shift its position, and the paper box loses its shape. It is possible to protect the sharp corners of the plate member without causing damage.

Overlapping pieces 7a and 7c are extended on the lower surface of 7d, respectively.

Then, the vertical fold line 1 and the horizontal fold line 4 are respectively bent inward, and the left and right bottom pieces 5a and 5c support the lower surface of the rear bottom piece 5b, and the lower surfaces of the left and right bottom pieces 5a and 5c are supported by the front bottom piece 5d. The tongue piece 8 provided at the tip of the front bottom piece 5d is inserted into the top of the bottom piece 5b from the inner end of the notch recess 9 provided in the rear bottom piece 5b to assemble the bottom wall. Further, the glue 3 is attached in advance to one side of the left side wall 2a to assemble the box with a bottom.

On the other hand, a cut groove 10 having a required width and depth in the vertical direction is provided in the center of the overlapping cover pieces 7a, 7c, and furthermore, on the extension line of the cut groove 10, the overlapping cover pieces 7a, 7c and the left and right side walls 2a , 2c are provided with two incision lines 11, 11 each spanning the horizontal fold line 6. Further, each of the overlapping lid pieces 7a, 7c is provided with a dividing line 12 at both rear ends of the cut groove 10, which communicates with the cut groove 10. In addition, a horizontal fold line 13 is provided at the tip of the upper cover pieces 7b, 7d at a position matching the distance L from one side end of the overlapping cover pieces 7a, 7c to the notch groove 10, and the horizontal fold line 13 is provided in the left-right direction via the fold line 13. A wide locking piece 14 is extended, and cuts 15, 15 are provided along the fold line 13 at both left and right ends of the locking piece 14.

16 has a height h' of each side wall 2a to 2d of the paper box A.
It is a cushioning material made by polymerizing multiple strip-shaped paperboard pieces, which are slightly lower than the height h of .

The paper box A loaded with the cushioning material 16 is manufactured by bending the overlapping lid pieces 7a and 7c inwardly at the fold line 6, and then folding the upper lid pieces 7b and 7d on the fold lines 6 and 1, respectively.
Cut grooves 10, 10 are bent inward at 3 and the left and right ends of the locking pieces 14, 14 are provided in the overlapping lid pieces 7a, 7c.
The notches 15, 15 are inserted into the overlapping lid piece 7 by further pushing it through each dividing line 12.
The upper lid pieces 7b and 7d are fixed by being engaged with the lower surfaces of the upper lids a and 7c. In this state, each locking piece 14, 14 stands upright in the paper box A, and each locking piece 14, 14 stands upright inside the paper box A.
A gap S of equal width is formed between the gap S and the cut grooves 10, 10 so as to traverse the upper cover.
