Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a spacer for holding a plate-shaped product such as a mirror so that it does not wobble in a packaging box.

(Prior Art) Generally, products that are easily damaged, such as mirrors, are stored in packaging boxes as shown in FIG. 6 or 7, and then shipped and sold. That is, as shown in FIG. 6, a recess 1 is formed in a lower box 100 made of polystyrene foam.
01 is formed, a mirror 102 etc. is housed in this recess 101, and a lid 103 made of cardboard or the like is placed over it.A packaging box 104 shown in FIG. A rectangular frame 106 made of foamed polystyrene is pasted, a mirror 107 is housed in the rectangular frame 106 as shown in FIG. Sealing tape 10 as shown in
At 9, both ends of the cardboard 105 are fastened.

(Problems to be solved by the invention) However, if a mirror or the like is simply stored in the rectangular recess 101 or the rectangular frame 106 as described above, the mirror will come off from the recess 101 and the rectangular frame 106 during transportation. Easily damaged when the packaging box is dropped. In addition, since the inside of the box often rattles, this rattling often causes cracks or breaks, and there is also the disadvantage that the packaging box itself is not strong enough to accommodate large mirrors.

The present inventor has devised this invention in view of the conventional problems as mentioned above, and the purpose is to be able to hold even a relatively large mirror without wobbling inside the box, and to To provide a flat material for forming a spacer that does not take up much space when stored in a factory and is easy to assemble.

(Means for Solving the Problems) In order to achieve the above object, the present invention includes a pair of first cuts along two opposite sides of the plate-shaped material, approximately half of the plate-shaped material such as cardboard. An H-shaped cut line consisting of a cut line and a second cut line formed between the first cut line is provided, and an end side of the half portion other than the two opposing sides and the second cut line are provided. A small H consisting of a pair of third cut lines along the two opposing sides and a fourth cut line formed between the third cut lines, approximately halfway between the two sides.
The gist thereof is that a shaped cut line is provided, and a bending line is provided between the first cut line and the third cut line.

(Embodiment) A preferred embodiment of the present invention will be described below in detail with reference to the accompanying drawings.

FIG. 1 is a developed view of the flat material according to the present invention, and for convenience of explanation, the upper part of the paper is the upper part of the flat material, and the lower part of the paper is the lower part of the flat material.

The flat material 1 is made of corrugated cardboard or thick paper, and has a quadrilateral shape, and the lower half 2 has a section along the left and right sides 3 and 4, and from the middle part of the material 1 toward the lower side 5 of the material 1. A pair of first cutting lines 6,
A second score line 7 parallel to the lower side 5 is formed between these first score lines 6, 6, and an H-shaped score line 8 is formed by these score lines 6, 6, 7. is formed. A score line 9 parallel to the score line 7 is formed above the second score line 7, and a punched portion 10 is formed between the score lines 7 and 9.

In addition, the lower half 2 of the material 1 has the above-mentioned left and right sides 3 and 4.
A small H consisting of a pair of short third cut lines 11, 11 along the line and a fourth cut line 12 connecting these third cut lines 11, 11 and parallel to the second cut line 7.
A cut line 13 is formed. This H-shaped cut line 1
3, the fourth score line 12 and the second score line 7
The distance l ₁ to the lower side 5 is equal to the distance l ₂ to the lower side 5.

Second bending lines 14, 14 are formed between the upper end portions of the first cutting lines 6, 6 and the left and right sides 3, 4, and are slightly below the second bending lines 14, 14. Other second bending lines 15, 15 are formed at.
In addition, the lower end portions of the third incision lines 11, 11 and the first
The first bending line 1 is between the lower end of the cutting lines 6 and 6.
6, 16, and the third incision line 11,
A first bending line 17 parallel to the first bending lines 16, 16 is formed between the upper end of the first cutting line 11 and slightly above the lower end of the first cutting lines 6, 6.

A spacer is created by folding the flat material 1 having the above-described structure as described below.

First, the first cutting lines 6, 6, the second cutting line 7, the third cutting line
A folded portion 18 surrounded by the cut lines 11, 11, the fourth cut line 12, and the first fold lines 17, 17
Fold back toward the front from the state shown in FIG. 1 to form the shape shown in FIG. 2. Then, the third cutting line 11,1
The lip portions 19, 19 formed by the first and fourth cut lines 12 appear in parallel.

Next, from the state shown in FIG.
Fold it back in the direction of the arrow in the figure around the bending lines 14 and 15. Then, the portion 18 comes into contact with the upper half of the material 1, and a spacer 20 as shown in FIG. 3 is completed.

Then, prepare two spacers 20, and
The upper and lower ends of the mirror are inserted between the lip portions 19 and 19 of each spacer, and the mirror is stored in the packaging box in this state.

FIG. 4 shows another embodiment, in which spacer 2 is formed by bending material 1.
Styrofoam 21 is interposed in the space S of 0. By doing so, the strength of the spacer 20 can be further improved.

Incidentally, as shown in FIG. 5, the cut line 9 may not be provided and the punched portion 10 may not be formed, and a spacer may be formed by using a material 1 having such a shape and folding it in the same manner as described above. can be made.

(Effect of the invention) As is clear from the above explanation, according to the invention, an H-shaped cut line is formed in approximately half of a plate-like member such as cardboard or cardboard, and the H-shaped cut line is formed in the half part. Form an H-shaped cut line smaller than the cut line,
Since a bending line is provided between this small H-shaped cut line and the above H-shaped cut line, the end of the mirror, etc. can be held by the simple operation of bending a single plate-shaped material. It is possible to make a spacer with a lip part, so that plate-shaped products such as mirrors do not rattle inside the packaging box, and there are many advantages such as being able to effectively prevent damage during transportation.
