Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a packaging box device used for housing household electrical appliances such as cathode ray tube displays.

2. Description of the Related Art In recent years, there has been a demand for packaging box devices that can be easily unpacked and sealed repeatedly.

An example of the above-mentioned conventional packaging box device will be described below with reference to the drawings.

FIGS. 3 and 4 show a perspective view and a sectional view of a conventional packaging box device.

In FIG. 3, 2 is a pair of upper outer flaps having tongue pieces 3 at both ends, 4 is a pair of upper inner flaps having an insertion opening 6 that engages with the tongue pieces 3, and 6 is a pair of upper inner flaps that are connected to both ends of the contents 70. It is a cushioning material.

The operation of the packaging box device configured as described above will be explained below.

First, a pair of bottom cushioning materials 8 are placed inside the bottom surface of the packaging box 1 whose bottom surface is sealed, and the contents 7 are inserted and combined with the top cushioning material 6.

Next, a pair of upper inner side flaps 4 having an insertion port 6 are provided.
When it is bent inward from the base portion 9, it is restrained by the upper surface cushioning material 6 and kept at a substantially right angle.

The tongue pieces 3 of the pair of upper outer flaps 2 are inserted into the respective insertion openings 6, and the tongue pieces 3 are formed in the insertion openings 6 at substantially both ends of the pair of upper inner flaps 4 having the insertion openings 6 held at approximately right angles. and sealed.

Problems to be Solved by the Invention However, in the above configuration, the top cushioning material 6 is located near the center of the joint between each pair of top flaps 2 and 4.
A space corresponding to the thickness of is created. When gravity or impact is applied from the top surface to the vicinity of the space at the center of the joint opening, each pair of top surface flaps 2 and 4 fall toward the inner surface of the packaging box 1, making it impossible to secure space.

Therefore, there is a problem that the top flaps 2 and 4 come into contact with the contents 7 or the contents 7 are exposed, which impairs the appearance quality, and foreign matter gets mixed into the inside of the packaging box 1, which also deteriorates the performance quality. It had a point.

In view of the above-mentioned problems, the present invention provides a packaging box device that can prevent depression near the center of the seam of each top flap 2.4 even if there is a space created by the thickness of the top cushioning material 6. It is something to do.

Means for Solving the Problems In order to solve the above-mentioned problems, the packaging box device of the present invention provides a pair of upper cushioning members with a locking portion near the center of the upper surface of each member, and each locking portion has, for example, approximately The structure is such that corrugated paper that is folded into a chevron shape or flat corrugated paper is engaged.

According to the present invention, due to the configuration in which the corrugated paper is engaged with the above-mentioned locking portion, even if a force is applied from above to the top flap of the packaging box, the top flap will fall due to the locking portion and the corrugated board. can be prevented.

EXAMPLE Hereinafter, a packaging box device according to an example of the present invention will be described with reference to the drawings. FIG. 1 shows a perspective view of a packaging box device in one embodiment of the present invention.

In FIG. 1, reference numeral 11 indicates a packaging box, 12 a pair of upper outer flaps having a tongue piece 13 formed thereon, 14 a pair of upper inner flaps having an insertion opening 15, and 16 a pair of upper cushioning materials. Reference numeral 17 indicates a pair of protrusions provided for the purpose of locking on the upper surface cushioning material 16, 18 indicates a corrugated paperboard formed by bending it into a substantially chevron shape, and 19 indicates the contents.

Regarding the packaging box device configured as above, the following is the first part.
The operation will be explained using FIG.

First, FIG. 2 shows a sectional view, in which the contents 19 are placed in a packaging box 11 whose bottom is sealed using a pair of bottom cushioning materials 2°. Next, a pair of upper surface cushioning materials 16 are placed on both ends of the upper surface of the content article 19. A pair of top cushioning materials 16
A corrugated paperboard 18 bent into a substantially chevron shape is secured inside a pair of protrusions 17 near the center of the upper surface of the board. Since the space between the substantially chevron-shaped corrugated paperboard 18 and the contents 19 is secured by the thickness a of the pair of upper surface cushioning materials 16, the contents 19 will not be damaged.

Next, when the pair of upper inner side flaps 14 having the insertion opening 16 are bent inward from the base portion 21, they are restrained by the upper cushioning material 16 and kept at a substantially right angle. Insert the tongue pieces 13 of the pair of upper outer flaps 12 in which the tongue pieces 13 are formed into the insertion openings 16 at substantially both ends of the pair of upper inner flaps 14 having the insertion openings 15 held at approximately right angles into the respective insertion openings 16. and seal it.

When gravity or impact is applied to the top center portion of the top 1% of the sealed packaging box 11, the approximately chevron-shaped corrugated paperboard 18 engaged with the pair of top cushioning materials 16 can withstand the gravity and impact. , each top flap 12.14 is supported by a substantially chevron-shaped corrugated paper and does not fall inward. Accordingly, each top flap 12.14 and
A spatial distance from the content item 19 is ensured by the substantially chevron-shaped corrugated paperboard 18, and the content item 19 is not contacted.

As described above, according to this embodiment, the pair of upper surface cushioning materials 1
6 is provided with a pair of protrusions 17 for the purpose of locking, and the protrusions 17 are used to lock the corrugated paperboard 18 bent into a substantially mountain shape between the pair of upper surface cushioning materials 16. Even when gravity or impact is applied, damage to the contents 19 at the end surfaces of the top flaps 12.14 due to depression of each pair of top flaps 12.14 is prevented, and the contents 19 are prevented from being exposed and the packaging box is protected. It is possible to prevent foreign matter from entering the inside of the container.

Furthermore, the purpose of securing a space between the substantially chevron-shaped corrugated paperboard 18 and the contents 19 is to prevent the contents from being deformed when gravity or impact is applied to the relatively weak central portion of the contents.

In the embodiment, the protrusion 17 for the purpose of locking is used, but the protrusion 17 for the purpose of locking may be a pair of grooves.

Although the corrugated paper 18 is bent into a substantially chevron shape, the corrugated paperboard 18 bent into a substantially chevron shape may be a flat plate of corrugated paper.

Effects of the Invention As described above, according to the present invention, a locking portion is provided in a pair of cushioning materials bonded between the packaging box body and the contents, and the locking portion is bent to form a substantially chevron shape. By engaging the cardboard or flat cardboard with the contents while maintaining a certain space, it is possible to prevent the top flaps of each packaging box from falling down, preventing damage to the contents and preventing exposure. It is possible to easily and inexpensively prevent foreign matter from entering the packaging box and prevent the upper surface of the contents from deforming.
