DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an assembling method and an assembling structure of an assembling type box-making box or an assembling box-shaped tray for storing goods and the like.

[0002]

2. Description of the Related Art A precision instrument product such as a computer and its related equipment and an electronic instrument product are usually stably held in a box assembly box having a storage section corresponding to the shape of the product, and thereafter, are stably held. In many cases, the box-making box is put in a separate inner box or decorative box, and then shipped from the factory. The box-making box used at that time uses a box-processed sheet,
It is bent at the factory and assembled into a box.

FIG. 1 is an exploded front view of a box material sheet (for example, a corrugated cardboard sheet) for making a box box which has been conventionally used. In FIG. 1, reference numeral 51 denotes a portion serving as a bottom surface of the assembled box, 52 and 53 are bent to form left and right wall surfaces, 54 and 55 are bent to form front and rear wall surfaces, and 60 is a portion serving as a bottom surface. A storage section forming section that is folded inward to form a product storage section. In FIG. 1, solid lines other than the solid line indicating the outer edge indicate cut lines, and broken lines indicate fold lines that are bent there.

A lock claw 52 formed at the tip of a bent piece serving as a left and right wall surface is provided on a portion 51 serving as a bottom surface of the box assembly.
a, 52b, and 53a are inserted into and engaged with the lock holes 51.
a, 51b, and 51c, and lock holes 51d, 51e, and 51f for inserting and engaging lock claws 54a, 55a, and 55b formed at the tips of bent pieces that form front and rear wall surfaces.

[0005] In addition to the lock claws described above, flaps 54c, 54 which are folded inward during assembly and provided for shape fixing are provided on the front and rear wall portions 54, 55.
d, 55c and 55d are formed.

On the other hand, a fold line (broken line portion) and a notch (solid line portion) for forming a storage space corresponding to the shape of the product to be stored are formed in the center of the storage portion forming section 60. Around the portion forming portion 60, the inner wall constituting pieces 60a, 60b,
60c are formed.

As shown in the drawing, in the case of this assembled box, in order to maintain the shape of the wall portion 52 formed by bending, the lock claw 52a at the tip end of the folded piece constituting the wall surface passes through the lock hole 51a of the bottom portion 51, It protrudes from the back surface of the bottom surface portion 51 and is firmly engaged with the lock hole 51a.

[0009]

However, in the case of the assembling method using the conventional structure as described above, when a new sheet that has been box-formed is bent and formed,
It is not easy to insert each lock claw into each lock hole. Especially, when the thickness of the box material sheet is large, the rebound of the bent portion is strong. However, there is a case that the work efficiency of the assembling is deteriorated and the lock claw cannot be properly engaged with the lock hole because the shape of the lock claw is slightly changed by the wave of the corrugated cardboard sheet.

Further, in the case of the conventional assembling structure, when looking at the assembled box, the locking claws are completely projected from the lock holes and engaged with emphasis on the shape stability of the assembled box. When storing a box in an assembly box, etc., the locking claws hit another assembly box, damaging that assembly box, or putting the assembly box containing the product in another box with the instruction manual etc. And other problems.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems.
An object of the present invention is to provide an assembling method of an assembling box and an assembling structure that do not leave extra projections or the like on the outer peripheral surface of the assembled box.

[0012]

According to the method of the present invention, in a method for assembling an assembled box in which a sheet-like box material is bent to form the box material into a predetermined shape, a bent piece of the bent box material is formed. The bent piece is fixed by using a tongue piece having a hinge mechanism formed on the box material to support the tip of the bent piece. Further, there is provided a method for assembling an assembled box that includes a lock hole and a lock claw that can be engaged with each other when the box material is bent, and that uses the lock hole and the lock claw to form the box material into a predetermined shape. The tongue piece is formed in advance at an edge of the lock hole, and the lock claw is supported using the tongue piece. According to these, at the time of assembling the assembled box, the folded piece can be fixed only by pressing the tongue piece inward using the hinge mechanism,
It is possible to efficiently assemble the assembly box. In particular,
In the case of a method of assembling an assembled box in which the box material is formed into a predetermined shape using the lock hole and the lock claw, the lock claw can be attached to the tongue piece without completely inserting the lock claw into the lock hole. Since the bent piece is fixed by being supported, it is possible to easily assemble the assembled box.

According to the present invention, there is provided an assembled box in which a sheet-like box material is bent and formed into a predetermined shape, wherein a bent piece of the bent box material has a tip portion formed on the box material. It is supported and fixed using a tongue piece having a hinge mechanism. Further, a lock box and a lock claw that can be engaged with each other when the box material is bent are provided, and in the case of the assembled box formed to have a predetermined shape using the lock hole and the lock claw, an edge of the lock hole is provided. The tongue piece is formed in a portion. A box using such a tongue piece does not require a rigid lock mechanism including a lock hole and a lock claw for fixing the bent portion. Therefore, even in the case of an assembled box formed into a predetermined shape using the lock claw and the lock claw, even if the lock claw is not completely inserted into the lock hole, the lock claw is supported by the tongue piece. Since the bent pieces are fixed, it is possible to easily assemble the assembled box.

The tongue is formed by a pair of cuts extending from the lock hole and a support between the ends of these cuts. According to this, the tongue piece can be easily formed at the time of punching the box material sheet together with the processing of the other parts. The lock claw has a tip located at the same position as the outer peripheral surface of the lock hole portion or inside the outer peripheral surface of the lock hole portion when assembled. If the lock claw is supported by the tongue piece, it is not necessary to penetrate the lock claw through the lock hole and firmly fix the bent piece. Thus, the lock claw is engaged at a position inside the outer peripheral surface of the lock hole. In addition, it is possible to improve the handling of the assembled box.

The tongue supports the bent piece at least at the time of assembling the box material. This is because once assembled as a box, the fixing force (engagement between the lock claw and the lock hole, the folding of the flap, the insertion pressure of the product, etc.) by other parts acts, so the assembled box Is considered to be almost never dismantled. Further, the hinge mechanism of the tongue is constituted by a support between the cut ends forming the tongue. According to this, the hinge mechanism can be formed very simply.

Further, the claw piece has a width at the tip end side wider than the width at the support portion side, for example, a trapezoidal shape or a semicircular shape. With this configuration, the tongue piece can be easily pressed, and the bent piece can be supported in a large area.

Further, in the apparatus provided with a bent piece which is bent so as to form a space therein, a spacer piece is provided at a tip of the bent piece, and the spacer piece is directed toward a peripheral wall surface so that the tip is substantially flush with the wall surface. It is characterized by being folded so as to touch. With this configuration, even when a product or the like is stored in the assembled box, the bent piece that comes into contact with the product is not crushed and deformed by the pressing force from the product, and the product is safely held by the constant maintained space. be able to.

[0018]

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

Embodiment 1 FIG. 4 is a box material (corrugated cardboard sheet) for making the box-making box according to the embodiment of the present invention.
FIG. In FIG. 4, 1 is a bottom portion,
Parts where 2, 3 are bent to form left and right wall surfaces, 4, 5
Is bent to form front and rear wall surfaces, and 6 is a bottom surface portion 1.
Is a storage section forming section that is folded inside the product to form a product storage section. In FIG. 4, solid lines other than the solid line indicating the outer edge indicate cut lines, and broken lines indicate fold lines bent there.

Lock holes 1a, 1b that can be engaged with lock claws 2a, 2b, 3a formed at the tips of the bent portions of the left and right wall surfaces when the bent pieces are bent. , 1c, and lock holes 1d, which can be engaged with lock claws 4a, 5a, 5b formed at the tips of the bent portions of the front and rear wall portions.
1e and 1f are formed. The length of each lock claw is preferably equal to or less than the thickness of the box material sheet so as not to protrude outward from the lock hole when engaging with each corresponding lock hole.

At the edge of each lock hole, a pair of notches 1 narrowing from the lock hole toward the inside of the bottom portion 1 are formed.
Crease line 11 connecting 1m to 16m and the cut end
The tongue pieces 11 to 16 composed of n to 16n are formed. Here, the fold line portion connecting the ends of the cuts is a support portion of each tongue piece 11 to 16 and functions as a hinge mechanism. When the box material sheet is thin, the tongue pieces 11 to 16 can be easily pressed at the time of assembling the assembled box. Therefore, it is not always necessary to provide the fold lines 11n to 16n in the box material sheet in advance. Absent.

The shape of these tongue pieces is not particularly limited, but if the width on the lock hole side is wider than the width on the support portion side, for example, a trapezoidal shape or a semicircular shape, the support portion between the cuts is formed. Is narrowed, so that the tongue piece can be easily pressed, and the angle of the cut start portion of the edge of the lock hole becomes obtuse, so that there is an advantage that an accident such as catching something at that portion can be prevented. In addition, a valley fold line is formed in the center of the tongue pieces 11 to 16, and when the tongue pieces 11 to 16 are pressed, the tongue pieces 11 to 16 are formed in a V-shape using the valley fold line. When the lock claws are supported, the support strength can be increased. In addition, slits that perform the same function may be provided as the cuts 11m to 16m that form the tongue pieces.

In addition to the locking claws already described, the flaps 4c, 4d, and 5 which are folded inward at the time of assembly to serve for fixing the shape of the assembled box are provided on the front and rear wall surfaces.
c, 5d are formed.

On the other hand, a cut (solid line) and a fold line (dashed line) for forming a storage space corresponding to the shape of the product to be stored are formed in the center of the storage portion forming section 6. The bottom portion 1 has a width corresponding to the space width formed inside the bent piece by bending the bent piece at the tip (innermost side) of the bent piece constituting the portion forming portion 6.
Spacer pieces 6a, 6 folded outwardly along
b, 6c. Further, on the periphery of the storage portion forming portion 6, inner wall constituting pieces 6d, 6e, 6f to be located inside the surrounding wall surface are formed.

The above-mentioned box material sheet is folded along each fold line to assemble the assembled box. When the folded pieces of the portions 2 to 5 serving as the front, rear, left and right wall surfaces are folded in the middle, Each locking claw is engaged with a corresponding locking hole in the portion 1 serving as a bottom surface, and a tongue provided in each locking hole is pressed inward, and the corresponding bent piece is supported and fixed by the tongue. I do. In this case, the engagement between the lock claw and the lock hole is insufficient due to the action of the support force of the hinge mechanism of the tongue piece and the repulsion force of the bent piece (for example, the lock claw is completely contained in the lock hole). (In a state where there is no), it is possible to greatly suppress the opened bent piece. Further, since the length of the lock claw is shorter than that of the related art, the lock claw can be smoothly engaged with the lock hole. Therefore, by using this structure or method, it is not necessary to repeat the insertion operation many times until the lock claw is completely inserted into the lock hole, and the assembling operation of the assembly box can be made much more efficient.

Further, the spacer piece 6 of the storage section forming section 6
By folding back the a, 6b, and 6c along the bottom surface portion 1 until the a, 6b, and 6c are almost in contact with the surrounding wall surface, the internal space width of the storage section forming section 6 formed by bending the storage section forming section 6 folded piece is constant. Will be retained. Thereby, deformation of the shape of the storage portion forming portion 6 due to pressing force or the like from the stored product is prevented.

FIG. 5 is a perspective view of the box-making box assembled by the above method. This box is composed of a bottom portion 1, left and right wall portions 2, 3, front and rear wall portions 4, 5, and a storage portion forming portion 6, and a product storage portion for storing and fixing products in the center thereof. 7 is provided. In the drawings, reference numerals 8 to 10 denote accessory storage sections for storing accessories (battery, cable, storage medium, and the like) of the product.

FIG. 6 is a partial cross-sectional view showing an engagement state between each lock hole and each lock claw, which is seen on the back side of the bottom surface of the box of FIG. 5, and here, the case of the lock hole 1a and the lock claw 2a is representative. I will explain. The other combinations are the same as those in FIG. As shown in the figure, in the case of this assembled box, the lock claw 2a at the tip of the bent piece constituting the wall part 2 is located inside the lock hole 1a on the bottom part 1 and is supported by the tongue piece 11, and the lock hole 1a does not protrude from the outer peripheral surface. Further, each lock claw also normally engages with both ends of each lock hole to contribute to fixing the bent piece. Once the box-making box is assembled, the folded pieces are combined with the lock holes and the lock claws, the flaps are folded, and the pressing force of the product placed in the product storage unit is combined. So it hardly opens in its natural state. From this perspective,
It can be said that the engagement state between the lock hole 1a and the lock claw 2a as shown in FIG. 6 only needs to be maintained at least during the assembling operation of the assembly box.

Embodiment 2 Here, an example will be described in which a bent piece bent to form an assembled box is supported and fixed without using the lock engagement shown in the previous example.
When assembling a box assembly using a box material sheet material that has a small repulsion force that repels the bending force, the bent piece once bent will not easily return to its original position. For example, three sides of a square (including a trapezoid) are cut, and the other side is bent only by a tongue piece having a support portion, that is, a hinge portion, without using a firm engagement like a nail. It is possible to support the folded piece (there may be a lock claw at the tip of the folded piece) in the folded state (to prevent it from returning).

FIG. 7 is an exploded view of such a box material sheet, and FIG. 8 is a partial cross-sectional view corresponding to FIG. 6 of the bottom of the assembled box assembled from the box material sheet. As shown in FIG. 7, in the case of this box material sheet, tongue pieces 11 to 1
6 is formed, but there is no lock hole. The bent piece 2 also has no lock claw. Then, as shown in FIG. 8, the inner bent piece 2 bent to constitute the wall surface portion 2 of the assembled box has a structure supported by the tongue piece 11 inside the bottom surface portion 1. As described above, once the box assembly box is assembled, the folded piece may be folded into the flap or the pressing force of the product stored in the product storage unit. Because it is fixed, it hardly opens in a natural state.

FIG. 9 is an explanatory diagram showing an example of packing using the assembled box (middle box 23) according to the embodiment of the present invention. The product main body 21 placed in the plastic bag 22 is stored in the product storage portion in the center of the middle box 23, and the pen set 24, the dry battery 25, and the storage medium 26, which are accessory parts, are stored in predetermined positions. Further, with the warranty card 27 placed above the middle box 23 and the instruction manual set 28 placed below the middle box 23,
They are inserted into the packaging box 29, the lid is closed, and the packing is completed. At the time of such packing, since the lock claw does not protrude from the back surface of the bottom portion of the inner box 23, the instruction manual set 2
The inner box 23 and the instruction manual set 28 can be efficiently stored in the individual box 29 without damaging the box 8 and the individual box 29.

In the above embodiment, the box-making box is taken as an example and the material is corrugated cardboard. However, the present invention can be applied to an assembly tray or the like according to the box-making box. As a material, a plastic or metal material that can be bent can be used. Further, in the above-described embodiment, an example is shown in which the tongue piece is provided on the bottom surface of the assembled box as an inner box having an open upper surface. However, the present invention is not limited to this, and various kinds of assembled boxes are used for assembling. It can be applied to support and fixation of bent pieces to be formed.

[0033]

As described above, according to the present invention,
When assembling the assembled box, the tongue piece is used to support the bent piece (or its lock claw) which has been bent, so that the bent piece can be easily and stably held, and the assembling workability of the assembled box is improved. Can contribute to the efficiency of In addition, since the lock claws of the assembled box can be prevented from protruding from the outer peripheral surface of the box, the handling and storage of the assembled box can be improved, and the disassembling operation of the assembled box can be easily performed.
