する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a corrugated cardboard box having openings at the top and bottom and having a velcro tape on the closing surface to be stacked. Since the velcro tape is used on the closing surface, it can be folded and assembled. In addition, the bottom has a three-layer structure so that even if a heavy object is accommodated, the bottom does not slip out and can withstand sufficiently, and the top has a structure of at least two layers.

Description of the Related Art Conventional top-and-bottom opening corrugated cardboard boxes are easy to deploy, but have a difficulty in the transition process both during deployment and assembly, and the corrugated cardboard boxes themselves are not complete. Therefore, when the contents are stored, the closing surface is adhered to fix the bottom portion, or the bottom surface is prevented from coming off even if a load is applied by reinforcing the closing surface with gum tape, staples, or the like.
Further, the upper surface opening portion also employs a similar joining means.

ラップを組むなどの手段によっていた。Since the corrugated cardboard box is mainly disposable, it has a short life cycle, and it is hard to say that it was made in consideration of its strength. In addition, adhesives, gum tape, and other auxiliary tools are always required at the time of assembly, so the corrugated cardboard itself is damaged at the time of unfolding, causing problems such as hindering reuse. In addition, the method of covering the reusable cardboard box is to assemble a four-sided flap into a swastika type.

耐えられない等の問題点があった。In order to apply the velcro tape to the conventional top-and-bottom opening type corrugated box structure, the velcro tape itself is relatively weak against the upper and lower peeling forces, and there is a problem that it cannot withstand the heavy load of contents. there were.

の横c方向への張り出しを防止している。In order to solve the above problems, the present invention is to devise the setting position of the magic tape by expanding the area of the closing surface per step related to the load bearing structure to the full size of the rectangular opening. Then, the load is directly replaced by the pulling resistance of the paper on the second step surface on the first step surface and the load drag force of the paper on the second step surface and the third step surface by the leverage principle. Also, in the case of stackable type, by extending the vertical width of the upper first step surface to a length of c / 2 or more and installing a magic tape in the overlapping center part, it can be moved in the horizontal c direction during stacking. To prevent overhang.

の固定手段と同等の強度を確保することができた。Since the closed surfaces are laminated, the heights of the adjacent lines of the side surfaces 3 and 4 are adjusted to prevent unreasonable friction between the surfaces. Further, since the velcro tape is weak in pulling force in the vertical direction and has extremely strong resistance to lateral displacement, it is necessary to arrange the velcro tape in consideration of its characteristics. By the arrangement described later, even with the velcro tape, it was possible to secure the same strength as the conventional adhesion and fixing means such as gum tape.

できる。When a 5 mm corrugated cardboard sheet is folded,
The inner extension loses, while the outer does not.
In other words, the line on the development plan becomes the surface dimension of the cardboard box. Therefore, when designing the inner volume space, an accurate design can be achieved by taking an extra 5 mm for the thickness of the sheet on the outside of the edge of the surface.

The sheet thickness of surface 4, surface 12 and surface 11 is t = 5 mm, and the thickness per sheet of the closed area layer portion of surface 5, surface 6, surface 8 and surface 7 is continuous pressing by use. Considering the loss due to the weight of the contents and the content, t '= 4.5 mm.

お、中央線24は説明のための仮定上の線である。Longitudinal design: In the design of the upper side surface height and the closed surface, the structure of the developed view is based on the surfaces 1 and 2. (See FIG. 2. Only in FIG. 2, the solid line is the cutting line and the dotted line is the center line of the fold line.) The extension line of the adjacent line 14 of the surface 1 coincides with the adjacent line 15 of the surface 2. Adjacent line 14-
Based on the extension of the adjacent line 15, the adjacent line 18 is the thickness (t ′) of the closed surface 5, and the adjacent line 19 is approximately the closed surface 5,
It is raised by a thickness of 6 from the center line 24. The center line 24 is a hypothetical line for explanation.

良い。(図3)In order to secure the inner volume dimension b, the adjacent line 14 and the adjacent line 15 are set higher than the upper limit of b by t as viewed from the center line 24. That is, from the center line 24 to the adjacent lines 14 and 1
The height up to 5 is b / 2 + t. Since there is no difference in altitude between the first and second surfaces 9 and 10, there is no need to adjust the height. In the case of the ordinary type, the vertical width of the surface 9 and the surface 10 may be about 10 cm because they serve only as a temporary support and side reinforcement of the second step surface 5. (Fig. 3)

Only the vertical length and shape of the upper closure surfaces 14,15.
In the stacking type, when the upper closing faces 10 and 9 are closed, the vertical length is c /
Set to 2 + t + f / 2. At the time of unfolding, in order to make it easier to insert a hand, the upper left corner of the closed surface 10 and the upper right corner of the closed surface 9 are cut into vertically long triangles. The closed surface 9 is also cut into a triangle with the upper left corner slightly smaller. (FIG. 4)

The vertical width of the surface 5 is also extended by 2t corresponding to the increase in the direction of the side surface a.

や内容物重量により、t´やdの値は変わる。Also, due to the height adjustment of the surface 6 itself, the adjacent line 19 is raised above the height of 18 by an additional 2.5 mm.
(Theoretically, the height difference with the adjacent line 15 is 2t ', which is 9mm, but if the 2mm extension is added to the length of the surface 6 from the empirical value, it will be finished more closely.) That is, the adjacent line 19 is adjacent. It is 7 mm higher than line 15 (d). Also, the vertical length increase of the surface 6 is (the increase of the side surface a direction 2t + the thickness of the surfaces 5 and 2t

長さは、それぞれc/2+tになる。Design of the lower part; here, the development view is rotated 180 degrees so that the length is extended to the lower surface of the original view.
From the point of view of 4, it will be "higher". The extension line of the lower end line 16 of the side surface 1 and the lower end line 17 of the side surface 2 coincide with each other in the same manner as the adjacent line 14-15. In order to secure the inner volume dimension b, the adjacent lines 16 and 17 are also t when viewed from the center line 24.
Is higher than the lower limit of b. Here, the closing surfaces 11 and 1
Since the two are combined to form the first step surface, the upper end line 22 and the upper end line 23 form a mating side. The vertical lengths of the closed surfaces 11 and 12 are c / 2 + t, respectively.

向の増過分2t=10mmだけ縦に長くなる。The adjacent line 20 to the side surface 4 of the second step surface 7 is also 4.5 mm (t ') higher than the adjacent line 16 due to the height adjustment of the surfaces 11 and 12 by the thickness of the surface 7 itself. Further, the surface 7 is lengthened by 2t = 10 mm in the a direction.

For the same reason as explained in No. 9, it is 7 mm higher than the adjacent line 16 (d). In addition, the surface 8 is (2t + 2t ′), like the surface 6.
-D = 12mm lengthens vertically.

Therefore, if the length of the opposite side on the development view is the same, it is correct. It is not rectangular. FIG. 5 shows the adhesive surface 13 as the surface 4
After fixing to, the bottom opening is looked up from below.
(In the example shown, the width of the adhesive joint 13 is set to 50 mm.
To make it easier to understand, the thickness of the side sheet of the cardboard box is drawn extremely thick.) By increasing the lateral width of surface 1 only by t, the lateral dimensions of the cardboard box surface in the a direction facing each other can be matched. I chose

部を除去する。In this case, when the bottom first step surface is tilted inward, a gap of t is formed at the contact portion of the adjacent line 20 of the face 12 on the gap with the face 11 whose lateral width is increased by 2t. For t, the depth width is set to a + 2t as in the case of the surface 11 by projecting from the lateral width of the surface 1 by t. The same applies to the upper 10 surfaces. Since the upper limit and the lower limit of the adhesive bonding portion 13 are extended to the same height as the upper and lower adjacent lines of the surface 1, overlapping portions are formed on the surface 10 and the surface 12 when the closed surface is closed. The solution is to divide the side that originally overlaps with the surfaces 10 and 12 of the adhesive joint 13 as shown in FIG. 6 into two layers at the center of the sheet core over a range of a depth of 15 mm or more (20 mm in the example) from the cut end. By adhering the separation layer (hatched portion), the sheet thickness is made about 2 mm only in that portion. Further, in order to avoid overlapping with the adhesive joint portion 13 on the surface 12, the shaded portion is removed as shown in FIG. 8 (on the surface 10, FIG. 7).
