Description

DETAILED DESCRIPTION OF THE INVENTION INDUSTRIAL APPLICATION The present invention relates to a packaging structure using a packaging box made of a cardboard board.

2. Description of the Related Art Conventionally, a packaging box with a handle as shown in FIGS. 5 to 8 has been known for convenient storage and carrying of electric appliances and the like.

In the following, a description will be given with reference to the drawings.
2a, 2b, 3a, 3b, and bottom plate forming flaps 4a, 4b, 5a, 5b connected to the lower end of each side plate 2a, 2b, 3a, 3b;
Upper lid forming flaps 6a, 6 connected to the upper ends of a, 2b, 3a, 3b
This is a packaging box made of a corrugated cardboard consisting of b, 7a, and 7b. In this packaging box 1, the bottom plate is formed by first folding the flap 4b at right angles to the side plate 2b, then folding the flaps 5a and 5b so as to overlap both ends of the flap 4b, and finally folding the flap 4a so as to overlap the flaps 5a and 5b. Center insert 4 of this flap 4a
a 'is inserted into the central recess 4b' of the flap 4b '. In addition, the top lid is first
Is folded at right angles to the side plates 3a, 3b, then the flapper 6a is folded so as to overlap with the flaps 7a, 7b, and then the flap 6b is folded so as to overlap with the flap 6a. The flap 6a and a side plate 2a connected to the flap 6a are inserted into a slit portion 8 formed at a continuous portion thereof. Finally, an insertion piece 6a 'cut out and formed at the center of the flap 6a is inserted into the flap 6b. It is formed by being inserted into a slit portion 9 formed at a portion connected to the piece 6b '. In addition, 10 is a handle member attached to this upper lid,
It is formed of resin, and the engagement portions 10 at both ends of the handle member 10 are formed.
a, 10a are engaged with the small holes 6a ", 6a" of the flap 6a so that the central gripping portion 10b projects above the hole 6b "of the flap 6b. Reference numeral 11 denotes the above-mentioned packaging box. An object to be stored, such as an air product, stored in the interior of the device 1 and both sides are protected by a cushion 12 made of a foam material.

Problems to be Solved by the Invention When the objects to be stored 11 are stored in such a conventional packaging box 1 and laid down sideways as shown in FIG.
In particular, the lower the packing box, the greater the load applied from above,
The engaging portions of the flaps 4a, 4b forming the bottom plate are expanded outward, so that the flaps 4a, 4b are easily disengaged, and there is a problem that the bottom is lost.

The present invention solves such a problem, and when packaging boxes containing objects to be stored inside are laid horizontally and stacked in a plurality of stages, the flap for forming the bottom plate is directed outward even when a large load is applied from above. An object of the present invention is to provide a packaging box that does not expand and open and does not have a bottom.

Means for Solving the Problems In order to solve this problem, the present invention is made of a corrugated cardboard plate, and is provided continuously with two sets of opposed side plates and a lower end of one set of the opposed side plates among the two sets of opposed side plates. A bottom box formed with a bottom plate forming flap and an upper lid forming flap connected to the upper ends of the two sets of opposed side plates, and a bottom plate connected to the lower end of the set of opposed side plates Of the forming flaps, one flap has substantially the same size as the bottom of the packaging box, the other flap overlaps the lower surface of one flap, and a plate that closes the bottom of the packaging box and both ends of this plate. The other set includes a pair of insertion pieces connected so as to be in contact with the inner surface of the lower end of the opposing side plate. At the lower end of the surface in contact with the inner surface of the opposing side plate, the shape of the insert A concave portion corresponding to the size is formed, and the concave portion of the buffer and the insertion piece are fitted in the packaging box.

According to this configuration, when the objects to be stored are stored in the packaging box, laid sideways, and stacked in a plurality of stages, even if a large load is applied to the packaging box from above, the insert piece of the other flap is inserted into the recess of the buffer. Since they are fitted, it is possible to prevent the insertion pieces from coming out when both flaps open outward.

An embodiment of the present invention will be described below with reference to the drawings (FIGS. 1 to 4). In the drawings, the same reference numerals as those in the conventional example denote the same members, and a detailed description thereof will be omitted.

The difference between the embodiment of the present invention and the conventional example is the structure of the flap for forming the bottom plate and the structure of the buffer.

That is, in the embodiment of the present invention, two sets of opposed side plates 2a, 2b, 3a, 3b
At the lower end of the pair, the bottom plate forming flaps 13a, 13b are continuously connected only to the lower end of one set of opposed side plates 2a, 2b on the long side, and the lower end of the other set of opposed side plates 3a, 3b on the short side. No flaps are connected. The flap 13a connected to the lower end of the side plate 2a has substantially the same size as the bottom of the packaging box 1,
The flap 13b connected to the lower end of the side plate 2b is in contact with a plate portion 13b 'of the same size as the flap 13a and the lower end inner surfaces of the other pair of opposing side plates 3a, 3b at both ends of the plate portion 13b'. It has insertion pieces 13b ", 13b" which are provided in series. Reference numeral 14 denotes a finger-holding recess formed on the end face of the flap 13a at the center in the horizontal length direction. Further, a buffer 12 made of a foam material for protecting both ends of the storage object 11 is provided on the other side plate of the other set.
The insertion pieces 13b ", 13b" are provided at the lower ends of the surfaces in contact with the inner surfaces of 3a, 3b.
A concave portion 15 is formed which conforms to the shape and size of. Other configurations are the same as those of the conventional example.

In the above configuration, when assembling the packaging box 1 and storing the storage object 11 therein, first, the flap 13a is folded at right angles to the side plate 2a, and then the flap 13b is placed so as to overlap the lower surface of the flap 13a. The portion 13b 'is folded and the insertion pieces 13b ", 13b" at both ends of the flap 13b are inserted so as to overlap the lower end inner surfaces of the other pair of opposing side plates 3a, 3b. The object to be stored 11 whose both ends are protected by the buffer 12 is stored in the packaging box 1 having the bottom plate formed in this manner. At this time, since the recesses 15 are formed in the buffer body 12 as described above, the recesses 15 are fitted with the insertion pieces 13b ″. As in the example, the upper lid forming flaps 6a, 6b, 7a and 7b are closed to form the upper lid, and the handle member 10 is attached to the upper lid.

The items to be stored in the packaging box 1 assembled as described above
When the package 11 is stored and laid on its side and stacked in a plurality of stages, even if a large load is
Since the insertion piece 13b "of b is fitted into the concave portion 15 of the cushioning body 12, it is possible to prevent the insertion pieces 13b" from coming out as the flaps 13a and 13b open outward. it can.

Effect of the Invention As described above, according to the present invention, when packaging boxes each containing objects to be stored are laid sideways and stacked in a plurality of stages, even when a large load is applied to the packaging boxes from above, the flap for forming the bottom plate is not affected. It does not bulge outward and open itself.
