Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a heavy-duty packaging box that is assembled by punching out a substrate of a sealing material such as paperboard, synthetic paper, or cardboard, and is particularly suitable for storing heavy objects.

<Example> An example of the present invention will be described below with reference to the accompanying drawings.

Figure 1 is an exploded view of the original packaging box, which consists of a piece of cardboard,
It is made of sheet material such as synthetic paper or cardboard. FIGS. 2 to 4 are explanatory views of the present invention during assembly, and FIG. 5 is a perspective view of the completed assembly. A, B, C, and D are the outer wall panels of the box, which are separated by an end line 1, vertical fold lines 2, 3, 4, and 5, and horizontal fold lines 1', 2', and are connected horizontally. The adhesive piece e is finally attached to the outside of A. Lids E and G, which touch these outer wall panels at horizontal fold line 1', are inner lids, H is E,
G is the inner lid, f is the insertion piece, and F is the outer lid.
I, J, K, L are the parts that form the bottom plate, and cut holes g, h,
Holes i, j, k and l are provided in sequence, and these holes are pierced laterally through the center by a line 3'. M, (N, O), which touches the bottom plates I, J, K, L by the horizontal fold line 4'
P and Q are the inner wall panels, and the assembled outer wall panels A, B,
It is overlapped inside C and D and contributes to increasing the strength. The sliding plate R is in contact with the inner wall plate O, and has an S-shaped cut a ₁ ,
It has a ₂ , a ₃ , a ₄ and vertical folds b ₁ , b ₂ , b ₃ , b ₄ and slides in the horizontal direction to form a partition frame. Moreover, the sliding plate S is in contact with the inner wall plate Q, and the S-shaped cuts c ₁ , c ₂ , c ₃ ,
c ₄ and vertical folds d ₁ , d ₂ , d ₃ , and d ₄ to form a partition frame by sliding in the horizontal direction. T is the horizontal central partition of the packaging box that contacts the sliding plate R at the fold 7', and the adhesive pieces n and o at both ends are bent and adhered to the center of the inner wall plates M and P. U is adhesively fixed to the back side of the central partition plate T with an adhesive sail in contact with the fold line 8'.

The weight-resistant packaging box of the present invention can be assembled from a single board having the above configuration as follows. First, when the bottom plates I, J, K, and L are folded outward from each other along the horizontal fold line 3' in the center, the part below the fold line overlaps the part above the fold line, as shown in Figure 2, and a part of the lid is slightly exposed. .

Next, the bottom plates are folded inward in the order of vertical fold lines 4, 3, and 2, and inserted sequentially between the corresponding edges with the edges of the cutout holes of the bottom plates overlapped, so that the bottom plates are all combined to form a double bottom plate. Along with this, the inner wall plate overlaps and is reinforced with the outer wall plate, forming a periphery of a substantially rectangular hexahedral box. FIG. 3 shows the initial stage of this assembly.

Next, fold the inner wall plate O, sliding plate R, and center partition plate T into the nearly completed box along the horizontal fold lines 5' and 7' as shown in Figure 4, and place the center partition plate T in the center. stand vertically to form a partition. In the same way, the adhesive plate U of the sliding plate S is bent along the horizontal fold lines 6' and 8', and the central partition plate T is attached back to back, and the adhesive pieces n and o at both ends of the central partition plate T are bent at right angles. Interior wall boards M, P
The adhesive strips e and m are then bonded together to the exterior wall board A, thus completing the assembly as shown in FIG. 5.

<Effects of the invention> In this invention, double bottom plates corresponding to the notched holes in the double folded bottom plate are combined to form an extremely thick bottom plate, and the inner wall plate is also reinforced by being overlapped with the outer wall plate. , suitable as a heavy-duty packaging box.

In addition, according to this invention, the central partition plate is pushed down together with the adhesive plate through the sliding plate, and the sliding plate is divided into two parts inside the inner wall plate, thereby making the overall structure of the box even stronger. There is.

Claims (1)

[Scope of claims for utility model registration] 1. Vertical fold lines 2, 3, 4, 5 and horizontal fold lines 1',
A series of exterior wall panels A, B, C, divided by 2'
D, the adhesive piece e, the lids E, F, G, H and the insertion piece f that are in contact with the outer wall board along the horizontal fold line 1'.
are provided in parallel on the upper side of the outer wall board, and the horizontal fold line 3' at the center and the notch holes g, h, i,
Bottom plates I, J, K, and L with j, k, and l, and inner wall plates M, N,
O, P, Q and adhesive piece m, in contact with inner wall board O, S-shaped cuts a ₁ , a ₂ , a ₃ , a ₄ and vertical folds
A horizontal sliding plate R having b ₁ , b ₂ , b ₃ , b ₄ contacts the inner wall plate Q at a horizontal fold line 6', and has an S-shaped cut c ₁ ,
c ₂ , c ₃ , c ₄ and a horizontal sliding plate S having vertical folds d ₁ , d ₂ , d ₃ , d ₄ and touching the sliding plate R at a horizontal fold line 7′. In one development board consisting of a central partition plate T and an adhesive plate U attached to the central partition plate T that contacts the sliding plate S at a fold line 8', a transverse fold line 3'
Then, while keeping the inner and outer wall panels stacked, bend the vertical fold lines 4, 3, and 2 inward in order, and insert the edges of the notched holes in sequence between the edges of the corresponding notched holes to assemble the bottom plate. The bottom plate and the overlapped inner and outer wall plates roughly form a box plate, and the horizontal sliding plates R and S are pushed into the box together with the central partition plate, and each sliding plate is made vertically. Bend the folds at right angles and move the S-shaped cut laterally to form multiple product insertion frames,
Furthermore, the center partition plate T and adhesive plate U are pushed down, and the back side of each plate is attached to complete the assembly of the heavy-duty packaging box. 2 Practical use characterized by inserting corresponding folded pieces between the folded edges of the notch holes sequentially provided along the center fold line of the bottom plate to form a double bottom plate, and at the same time making the inner and outer side wall plates overlap. The weight-resistant packaging box according to claim 1 of the patent registration claim.
