Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a packaging container used for packaging electrical products and other various products.

[Conventional technology]

When packaging electrical products such as television receivers, a cushioning molded material made of styrofoam or the like is placed around the electrical product and placed in a packaging container to secure the product inside the container. In this case, packaging containers shown in FIGS. 8 to 10 have conventionally been generally used. This packaging container has left and right locking pieces 53, 54 of a top wall flap 52 connected to a front wall 51,
and a ceiling wall flap 56 connected to the back wall 55
The left and right locking pieces 57 and 58 are connected to a pair of left and right slits 6 formed in the top wall flap 60 of the left side wall 59.
1, 62, and the top wall flap 64 of the right side wall 63
The top wall portion of the packaging container can be sealed by inserting and locking into a pair of left and right slits 65 and 66 formed in the slits 65 and 66, respectively.

However, in the conventional structure described above, the left and right locking pieces 53, 54 and 57, 58 of the ceiling wall flaps 52, 56, which are arranged to face each other, are placed on both sides of each other, as shown in FIG. Since the structure is such that the top wall flaps 60, 64 are simply inserted into the slits 61, 62, 65, 66 located at In this case, large molded cushioning bodies B and C must be used to secure product A stored inside the packaging container.
Therefore, a large amount of material for the cushioning molded body was required.

In addition, as disclosed in Japanese Utility Model Application No. 52-107925, in cases where the product is packed inside the container only by the repulsive force of the top wall flap of the packaging container, the cushioning molded body is not used, so the cushioning Although it is possible to significantly reduce the cost by reducing the material cost of the formed body, it is not possible to reliably hold the product inside the container, so if the packaging container is subject to disturbance such as during product transportation. However, there was a problem in that looseness occurred between the packaging container and the product, and the packaging container could no longer perform its original function of protecting the product.

[Purpose of invention]

The present invention has been developed in consideration of the problems of the conventional methods described above, and the packaging container itself takes over a part of the cushioning molded body that protects the product inside the packaging container. Therefore, the object of the present invention is to provide a packaging container which can reduce the amount of cushioning molded material used and which can reliably hold the product inside the container.

[Structure of the idea]

The packaging container according to the present invention is provided with a cushioning molded body that is placed between the top wall flap and the product packed inside the container to hold the product inside the container when the top wall flap is closed. , one of the top wall flaps of the packaging container is folded inward and tilted slightly diagonally downward; It is characterized in that it is pressed against one end surface of the buffer molded body to hold the product inside the container.

Further, the left top wall flap 24 connected to the upper end of the left wall side 2 via a crease line 23 has a vertically elongated slit 25 at its center, and a crease line 26 is provided in the horizontal direction close to above the elongated slit 25. It is being This left top wall flap 24 has the function of taking over a part of the cushioning molded body B' for protecting and fixing the product A, as will be described later. Further, at the upper end of the rear wall 3, a rear ceiling wall flap 27, which is bilaterally symmetrical to the front ceiling wall flap 18, is connected to the upper end of the rear wall 3 via a crease 28.
That is, this rear ceiling wall flap 27 has a locking piece 29 on the right side of the upper end that can be engaged with the vertically long slit 25.
are connected to each other via a crease line 30, and a notch 31 is formed on the upper left side of the upper end of the flap 27 to extend vertically from the upper end. Furthermore, a right side ceiling wall flap 3 is attached to the upper end of the right side wall 4 via a crease line 32.
3 are connected. This right side ceiling wall flap 33
has a folding line 34 extending parallel to the folding line 32, and a locking protrusion 35 is formed at the center of the upper end of the flap 33, which can be engaged with the alignment slit forming part of the notches 22 and 31. has been done.

In the above structure, the procedure for assembling the packaging container and packaging product A is as follows.

First, the crease lines 5 to 7 and 9 are each bent inward to form a rectangular cylinder shape in plan, and the glue allowance piece 8 is
is glued to the inner edge of the right side wall 4. Next, the four bottom wall flaps 10 to 13 are folded inward along the crease lines 14 to 17 and fixed by any suitable means. In this state, the product A is placed inside the packaging container as shown in Fig. 2. At this time, as shown in Fig. 7, the cushioning molded bodies B' and C are applied to the top, bottom, left and right parts of the product A, and the packaging container is placed inside the packaging container. These cushioning molded bodies are stored inside
