Description

[Detailed Description of the Invention] This invention relates to a packaging box with a handle made of cardboard, cardboard, etc., and particularly to improvements in reinforcing the handle.

A packaging box with a handle has a handle hole in the side wall of the box, and in order to reinforce this hole, conventionally a separate piece of reinforcing material has been glued to the handle hole.

In this case, the process of gluing the separate pieces is done manually, so
It is difficult to work with, and since it is difficult to match the dimensions of the holes, there are also problems in terms of quality, and the manufacturing cost is high.

This invention solves the above-mentioned drawbacks of the conventional ones, increases the compressive strength of the packaging box, mechanically joins seams to improve quality, and provides a packaging box with handles that can be manufactured at low cost. It is an object.

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

Figure 1 is a developed view of the embodiment, and in the figure 1, 2, 3
．． Reference numeral 4 denotes the side wall portion of the box, which is made up of four pieces connected across the fold 5. Of these, side wall portions 1 and 3 are the width side wall portion of the box, and side wall portions 2 and 4 are the length side wall portions. It is adapted to constitute a side wall portion.

Reference numeral 6 denotes a seam continuous to the side wall 4 at the end, 7 a handle hole provided in the side wall 1 at the other end which overlaps with this joint, and 8 the seam 6 corresponding to this handle hole. 9 is an inner flap provided above and below the side walls 1 and 3, and 10 is an outer flap provided above and below the side walls 2 and 4.

In this embodiment, the notch 8 is a hole that completely matches the handle hole 7.

FIG. 2 is a part of a developed view showing another embodiment. In the figure, 4.5 and 6.10 indicate the same parts as in FIG. It is set up in a shape.

FIG. 3 is a plan view showing the assembled state of the box, and the box has folds 5.
The part is bent and the seam 6 is overlapped on the inside of the side wall part 1, and with the handle hole 7 and the notch part 8 aligned, they are joined with adhesive, adhesive tape, stitching wire, etc., and the side wall part 1 is assembled.
-4 are formed.

The bottom surface of the box is formed by bending a lower inner flap 9 at right angles to the side walls 1 to 4 and then joining a lower outer flap 10 thereon.

The ceiling wall of the box is also formed in a similar manner.

In the packaging box constructed in this manner, the handle hole 7 is reinforced by the seam 6, so that a strong handle can be constructed.

Since the seam 6 is used to reinforce the handle hole 7, it is longer than the seam of conventional products, and when it overlaps and joins the side wall 1, the compressive strength of the entire box increases.

Since the overlapping and joining of the side wall portion 1 and the seam 6 can be performed by mechanical operations, the quality is stable, the manufacturing time is short, and the manufacturing cost can be reduced.

In addition, although the above-mentioned example explained the example which provided one handle, the number is not limited.

Further, although the entire joint is constructed to be long in order to provide the notch, it is also possible to make only the notch portion long.

The shape of the notch does not need to completely match the handle hole, and may be of any other shape as long as it can reinforce the portion of the handle hole where the hand is placed.

As described above, according to this invention, the compressive strength of the packaging box is increased, and the quality is improved by mechanically joining the seams.
It has the advantage that it can be manufactured at low cost.

[Brief explanation of drawings]

FIG. 1 is a developed view showing one embodiment of this invention, FIG. 2 is a partially developed view showing another embodiment, and FIG. 3 is a plan view showing the assembled state of the box shown in FIG. 1. In the figure, 1, 2, 3.4 are side wall parts, 5 is a fold, 6 is a seam, 7 is a handle hole, and 8 is a notch. Note that the same reference numerals in each figure indicate the same or corresponding parts.
