The front top plate 111 folded horizontally into the box 100, the upper side of the back of the packaging box 100, the rear top plate 112, the left side 103 and the right side 104 of the horizontally folded inside the box 100 Side fastening pieces 121 which are folded inclined into the box 100, and the front handle piece 131 which is folded upward in each of the front top plate 111 and the rear top plate 112 and is in contact with each other, and has a handle cutout 140 formed therein. And a rear handle piece 133, and protrusions 135 formed on both inclined sides of the front handle piece 131 and the rear handle piece 133 are formed in the side fastening piece 121. Inserted into the packaging box 100 is assembled.

 Hereinafter, the packaging box configured as described above will be described in detail.

Looking at the development of the packaging box 100 shown in Figure 1, the portion corresponding to the front surface 102 of the packaging box is located in the center of the development view, the left side 103 and the right side (right and left respectively) 104 is connected to be folded, the back side 105 is connected to the side of the right side 104 is folded. And the attachment piece 106 is formed in the side part of the back surface 105 in contact with the inner surface of the front surface 102. As shown in FIG. Therefore, the adhesive is applied to the attachment piece 106 while the front face 102, the left face 103, the right face 104, and the back face 105 are folded in a square shape, and the attachment piece 106 is placed on the front face 102. When attached to the inner surface has a square shape.

On the other hand, the lower surface of the front surface 102, the left surface 103, the right surface 104 and the rear surface 105, the bottom fastening pieces 122 forming the bottom surface 101 are formed so that they can overlap each other, The bottom surface 101 is formed by apply | coating and attaching an adhesive to the site | part which the bottom fastening piece 122 overlaps. Here, the bottom surface 101 may be formed by attaching the bottom fastening pieces 122 with an adhesive, but in some cases, the bottom surface 101 may be formed by weaving the bottom fastening pieces 122. When the bottom surface 101 is formed by weaving, the contents filled therein are supported by the stiffness of the woven bottom fastening pieces 122. The formation of the bottom surface 101 is the same as that of the conventional packing box bottom surface and a detailed description thereof will be omitted, and the stiffness of the bottom surface 101 withstanding load as the area of the bottom fastening piece 122 is widened is also proportional. To increase. Using the above characteristics, the floor fastening piece 122 may be configured to sufficiently endure the appropriate load filled in the packing box 100, and in some cases, the bottom fastening piece 122 may be attached and fixed with adhesive to increase rigidity. Can be.

On the other hand, as shown in Figures 2 to 4, the front top plate 111 is connected to the upper end of the front surface 102 and the front top plate 111 is located horizontally folded inward of the packaging box (100). The rear upper plate 112 formed at the upper end of the back 105 is also positioned horizontally folded inwardly of the packaging box 100. The front handle piece 131 is connected to the front top plate 111 so as to be folded vertically upward, and the rear handle piece 133 is connected to the rear top plate 112 so as to be folded vertically upward.

Accordingly, when the front top plate 111 and the rear top plate 112 are horizontally positioned inwardly of the packing box 100, the front handle piece 131 and the rear handle piece 133 are located in contact with each other.

The front handle piece 131 and the rear handle piece 133 is formed with a handle cutout 140 in the horizontal direction. The handle cutout 140 has a trapezoidal shape, and the upper side 141 of the handle cutout 140 is shorter in length than the lower side 142. And both the hypotenuse side 143 and the lower side 142 of the trapezoidal incision, the upper side 141 of the trapezoid is cut in the state connected to the handle pieces (131, 133) inside the handle pieces (131, 133) It is configured to be folded.

 As the handle cutout 140 is formed in a trapezoidal shape as described above, the user folds the handle cutout 140 to form a handle ball 145 and inserts fingers into the handle ball 145 to grip the handle pieces 131 and 133. Then, when the packing box 100 is lifted, the load transmitted to the handle pieces 131 and 133 is distributed downward in the form of a trapezoid. As the load is widely distributed downward, the handle pieces 131 and 133 are not torn as compared with the case where the load is concentrated.

In addition, the front handle piece 131 and the rear handle piece 133 is a structure in contact with each other, conventionally, the upper end of the handle pieces are bent inwardly in contact with each other once to improve the rigidity, in the present invention, the rigidity through the other structure As it is not necessary to bend the upper ends of the handle pieces 131 and 133 separately, the assembly process is simplified by reducing the process.

In addition, the protrusions 135 corresponding to both sides of the front handle piece 131 and the rear handle piece 133 are formed on the front handle piece 131 and the rear handle piece 133, respectively. The two projections 135 formed on the four sides of the handle pieces 131 and 133 are in contact with each other when the front handle piece 131 and the rear handle piece 133 are in contact with each other.

On the other hand, in the side fastening piece 121, two slots 125 are formed in a line along the inclined surface at the center thereof, when the side fastening piece 121 is folded into the inner side of the packing box 100, the front handle piece 131 ) And protrusions 135 formed on the rear handle piece 133 are respectively inserted into the slots 125 in contact with each other.

As the protrusions 135 are formed along the inclined sides of the front / back handle pieces 131 and 133, respectively, the lengths of the inclined sides become longer to form two protrusions 135, thereby lowering the inclination angle. As the inclination angle of the inclined side is lowered, the side fastening pieces 121 are deeply entered into the inner side of the packing box 100 and are gripped and lifted through the handle balls 145 formed on the front / back handle pieces 131 and 133. The back handle piece (131, 133) is stably supported so as not to be torn.

In this way, the two front projections 131 and the two rear projections 135 formed on both side inclined sides of the rear handle piece 133 are inserted into the slot 125 in contact with each other, thereby the front handle piece 131 and the rear surface. The handle piece 133 remains in contact with each other without opening, and in this state, the user grips the handle cut portion 140 formed on the front handle piece 131 and the rear handle piece 133. Through the handle ball 145 formed by folding the handle cutout 140 formed in the) it is possible to conveniently grasp the packaging box 100.

On the other hand, the slot 125 is designed in a structure that can withstand the load transmitted to the protrusion 135 sufficiently. The slot 125 has a rectangular structure and is formed along the inclined surface at the center of the side fastening piece 121. Therefore, when the user lifts the packing box 100 in a state in which the protrusions 135 are inserted into the slot 125 of the rectangular structure, the load is concentrated on the surface in contact with the protrusion 135 and the slot 125.

And the load transmitted to the slot 125 is concentrated on the upper short side of the rectangular slot 125, the short side is a linear structure so that the load is distributed along the length of the short side. If the short side of the slot 125 is formed in a curved semicircle structure, the side fastener is torn from the slot by the load while the load is concentrated at a point inside the semicircle.

And as the protrusions 135 are inserted into the two slots 125, the force is dispersed than the case where the protrusions are inserted into one slot, thereby providing excellent durability.

In the packaging box 100 configured as described above, in order to further improve durability, the packaging box 100 is formed in a direction perpendicular to the grain direction of the corrugated cardboard (the longitudinal direction of the dashed-dotted line in FIG. 2). In general, corrugated paper is divided into an inner skin formed into a corrugated form and an outer skin attached to both sides of the endothelial. Is formed.

On the other hand, two or more 'packing box' shown in the domestic design application No. 2009-18873 in the packaging box configured as described above can be easily transported, stored, and managed in the packaging box of the present invention. In addition, the protrusion 135 may be drawn out from the slot 125 so that the packaging box accommodated therein may be easily taken out in the state where the front handle piece 131 and the rear handle piece 133 are opened.
