Description

[Detailed description of the invention] The present invention relates to an assembly box consisting of a bottom plate and four side plates.
In particular, the present invention relates to an assembly box that is assembled by punching out a sheet of composite paper or the like.

Traditionally, a single sheet of thick paper such as composite paper is punched out,
A box is known in which a bottom plate and four side plates are integrally formed, and the box is assembled by folding these side plates.

However, in order to maintain these four side plates assembled together, a locking means is required that is cut out from a separate member, which requires a large amount of material and a large number of parts that make up the box. Furthermore, there was a problem in that it was troublesome to assemble.

The present invention was developed in view of these problems, and includes four side plates that are connected to each other through folding lines made of, for example, half-cut lines on the four sides of the bottom plate. In an assembly box made up of parts that are assembled together, a pair of side plates facing each other is provided with a width approximately twice the thickness of the side plates at the combination position at both ends thereof, extending in the height direction of the side plates, and extending in the upper end. At the same time, a slit-like cut with an open side plate is formed, and a combination piece extending laterally of the remaining pair of side plates is provided at the combination position of both ends of the remaining pair of side plates, and a folding line is formed at the tip of this combination piece. A locking piece is provided through the
Insert the combination piece into the slit-like cut, bend the locking piece along the bending line, insert the tip of the locking piece into the slit-like cut, and then The present invention relates to an assembly box characterized in that a stepped portion formed at a lower portion is engaged with a lower end of the slit-like cut.

Therefore, the box can be constructed from a single continuous sheet-like body, which reduces the amount of material used and facilitates assembly.

An embodiment of the present invention will be described below with reference to the drawings.

As shown in FIG. 1, this assembly box is made by laminating a plurality of sheets of paper, for example, a substantially square sheet (paperboard) cut from composite laminated paper with a thickness of 2 mm.

The front and back sides of this composite paper are made of decorative paper printed with a suitable pattern, such as wood grain, etc.
This gives the assembled box an appropriate aesthetic appearance.

The materials for the sheet-like body are not limited to those listed in -, but include composite laminated materials in which aluminum foil is placed on the surface or inside and laminated with other paperboard, and paperboard made of natural wood. Composite laminates made by gluing the obtained sheets together, composite laminates made by laminating paper on sheets of chemical products such as styrofoam and styrene foam, and composite laminates made by gluing natural sheets and Western paper together. A composite laminated material made by laminating a natural wood sheet and a chemical film with adhesive, etc. can be appropriately selected depending on the intended use.

Then, by using this sheet-like body, the bottom plate 1 and the four sides of this bottom plate 1 are provided with folding lines 2, respectively. 3. 4. Four side plates 6, 7° 8.9 are made, which are respectively connected via 5.

The four side plates 6, 7° 8.9 are separated from each other by embedding lines 10° 11, 12.13 formed by punching with a press near the corner portions of the sheet-like body.

Also, these four side plates 6. 7. 8. 9, a pair of side plates 6 and 8 facing each other have side plates 6 on both ends thereof.
, 8 are formed with pairs of slit-like cuts 14 extending in the height direction.

Note that these notches 14 were also formed at the same time as the punching by the press, and when assembled, the upper end of these notches 14 is open, and the side plate 6
, 7. 8. It has a width twice the thickness of the plate No. 9.

Correspondingly, at both ends of the remaining pair of side plates 7, 9, combination pieces 15, which are combined with the slit-shaped cut 14, extend laterally of these side plates 7, 9 and are integrally connected. ing.

Further, locking pieces 17 are integrally connected to the tips of these combination pieces 15 via folding lines 16, respectively.

A stepped portion 18 is cut out and formed in the lower part of the distal end side of the locking piece 17 in the assembled state.

To assemble the sea-shaped body constructed in this way to obtain a box, first fold the side plates 7 and 9 inward at right angles to the bottom plate 1 along the folding line 3°5, as shown in Figure 2. bend.

Next, as shown in FIG. 3, the remaining two side plates 6 and 8 are bent inwardly at right angles to the bottom plate 1 along folding lines 2 and 4.

At this time, the slit-shaped cut 14 relatively receives the combination pieces 15 at both ends of the side plate 7.9 which have already been bent.

Note that the arcuate portion 19 of the above-mentioned cut line 10.11.12.13 (see Fig. 1) corresponds to the rotation locus of the lower end of the sulin I-shaped cut 14 when the side plates 6, 8 are bent and rotated. Because they are aligned, the lower end of the notch 14 is in contact with this arcuate portion 19 while the slit-like notch 14
and the combination piece 15 are combined with each other.

Next, as shown in FIG. 4, the locking piece 1 is
7 is bent inward by 180° so that the locking piece 17 overlaps the combination piece 15.

As a result, the tip portion of the locking piece 17 clicks into the slit-shaped notch 14 of the side plates 6 and 8 while elastically deforming the vicinity thereof.

Moreover, a stepped portion 18 is formed at the tip of the locking piece 17, so that when the tip of the locking piece 17 engages with the notch 14,
The step 18 engages with the lower end of the notch 14 in the height direction, and the side plates 6, 8 on which the notch 14 is formed are held between this step 18 and the vertical portion 22 of the incision line 10, 11, 12° 13. Ru.

Therefore, the side plate 6. 7. 8. 9 will be held in combination with each other.

As a result, an assembly box 20 as shown in FIG. 5 is obtained.

In addition, this assembly box 20 has a folding line 2 on the bottom surface of the bottom plate 1.
3. 4. 5 to form a side plate 6. 7. 8. 9 are bent inward, so that the bottom plate 1 and side plates 6.9 are bent as shown in FIG. 7. 8. A step portion 21 perpendicular to the bending portion with 9 is formed.

Therefore, if the sheet-like body constituting this box has sufficient thickness, this step 21 and the edge of the upper opening of the lower box 20 will engage with each other, thereby allowing multiple boxes 20 to be stacked together. It can be held stably without causing the loads to collapse when stacked.

As mentioned above, the present invention comprises a bottom plate, side plates connected to the four sides of the bottom, a combination piece for combining both ends of these side plates, and four side plates. Since the locking pieces that hold each other in the assembled state are integrally constructed, the members constituting the assembly box can be a single sheet-like body, and the number of members can be reduced. .

Further, according to the present invention, the sheet-like material for assembling the box can be obtained by punching out a rectangular or square sheet-like material, and what is discarded during this punching is a slit-like material. It is possible to omit the notch and the stepped portion to form only the constituting portion, thereby greatly reducing material waste.

Further, according to the present invention, this box uses a punched sheet-like body, and the first step is to bend a pair of side plates on which the combination pieces are provided, and the other step is to form a slit-like cut. The second step of bending the pair of side plates and the third step of bending and engaging the locking pieces are omitted, which reduces the number of assembly steps and facilitates assembly.

Furthermore, according to the present invention, a large number of sheet-like objects obtained by punching out materials can be stacked in a flat state for transportation and storage, which reduces the space required for transportation and storage. can do.

In addition, according to the present invention, in the assembled state, a right-angled step is formed on the outer periphery of the bent portion of the bottom plate and side plate, and this step engages with the opening edge of the lower box. do,
When these boxes are stacked one on top of the other, they can be held stably without causing any damage.
