Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to packaging boxes for storing relatively heavy items to be packaged.

Conventional Structure and Problems Conventionally, this type of packaging box has been provided with hand holes in two opposing side plates, and the packaging boxes have been connected by placing hands in the hand holes. However, when it is attempted to store heavy items in this packaging box and arrange them in a row, there is a problem in that the packaging box is damaged because the hand holes do not have sufficient strength.

OBJECTS OF THE INVENTION In view of the above-mentioned conventional problems, the present invention provides a packaging box that will not be damaged even when relatively heavy items are stored in the packaging boxes and the packaging boxes are arranged one after another.

Structure of the Invention In order to achieve the above-mentioned object, the packaging box of the present invention has four parts formed by bending the side plates and the bottom plate at the lower end of the substantially center of two opposing side plates, and the object to be packaged comes into contact with the four parts. The structure is such that it is supported by the bottom cushioning material.

With this configuration, the bottom surface of the packaged object is in contact with the top surface of the four parts, so that the four parts will not be damaged even if you put your hand on the recess when connecting them.

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

In Figures 1 to 7, 1 is a side plate, 2 is a pair of outer flaps provided in series with the side plate 1, and 3 is a pair of outer flaps provided in series with the side plate 1.
A pair of inner flaps 1, these inner and outer flaps 2, 3 forming a bottom plate. 4 is the outer flap 2. The ruled line 5 between the inner flap 3 and the side plate 1 is two notches made perpendicular to the ruled line 4 in the side plate 1, outer flap, and tab 2 beyond the lower ruled line 4. A ruled line 6 connecting the upper and lower ends of the notch 5 is provided, and a ruled line 7 is provided slightly below the ruled line 4 and parallel to the ruled line 4, and by bending these ruled lines 4, 6, and 7, a handbag part is formed. A recess 8 is formed. Further, reference numeral 9 denotes a notch made for a predetermined length from the edge of the inner flap 3 on the side of the outer flap 2 in parallel with the ruled line 4, and from the end of the notch 9 on the side opposite to the outer flap side to the side opposite to the side plate 1. A ruled line 1o is provided, and the side surface 11 of the recessed portion 8 is formed by bending the ruled line a4.1O.

12 is a notch in the top cushioning material 13, 14 is a notch in the bottom cushioning material 16, and the packaged object 16 is supported by the notch 12.14.

Next, the dimensional relationship of each part will be explained. Bottom cushioning material 15
The height p is the distance i between the lower ruled line 4 between the side plate 1 and the outer flap 2 and the ruled line 6 at the lower end of the notch 5, and the inner flap and the knob 3.
It is equal to the difference between the plate thickness t and the plate thickness t. As a result, the height of the four parts 8 is lower than the height of the packaged object 16 placed on the bottom cushioning material 15.
The height will be the same as that of the bottom plate.

Also, the length h of the notch 9 of the inner flap 3 is equal to the length h of the notch 6
The length on the side plate 1 shall be H or more, and the ruled line 1o of the notch 9
The length of the ruled line 7 shall be equal to or more than half the length L of the ruled line 7. Thereby, the portion surrounded by the notch 9 and the ruled line 10 can be folded in to form the side surface portion 11, and the openings formed on both sides of the recessed portion 8 can be closed.

Further, when forming the recess 8 as shown in FIG. 7, the side plate 1 and the lower outer flap 2 can be easily folded in by folding in the ruled lines 7.

From the above, since the concave portion 8, which is the handbag portion, is in contact with the packaged object 16, even if you put your hand on the concave portion 8 and lift it up, the force will only be applied to the top surface of the four parts 8, and the handbag portion will not be damaged. . Furthermore, both sides of the recess 8 are closed by side parts 11,
A handbag can be provided without creating an opening, so
This prevents dust from entering inside. Further, since the ruled lines 7 are provided, the side plate 1 and the outer flap 2 can be easily folded in, and a recessed portion can be easily created.

Note that the ruled line 7 may be provided on the outer frame, the knob 2, or on the side plate 1, and the recess 8 may be provided on the inner frame. It goes without saying that the side wall 11 may be provided on the side plate 1 corresponding to the knob 3 and on the knob 2.

Effects of the Invention As is clear from the description of the above embodiments, according to the packaging box of the present invention, the object to be packaged is located directly above the carrying portion, so that lifting force is applied directly to the object to be packaged. Even if the packaged item is relatively heavy, the packaging box will not be damaged.
