Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a packaging device for an electric kotatsu, and is intended to reduce the cost of packaging materials and simplify the packaging operation.

Structure of conventional example and its problems As shown in Fig. 6, conventional electric kotatsu packaging includes a storage box 22 in which two of the four kotatsu legs 21 are folded out of cardboard, or a Styrofoam molded product. The heating element 23 and frame 24 of the kotatsu
It was located between. In addition, the most important thing to be careful about when packaging the electric kotatsu is to prevent the heating element of the kotatsu from being damaged by a depression in the center of the box when the outer box 25 is flat and stored stacked in a warehouse or the like. In the conventional product, a square-shaped frame 26 made of cardboard or the like is provided around the heating element 23 for reinforcement. This type of packaging requires a large amount of materials, takes a lot of time for packaging, and is uneconomical.It also requires a large number of parts, which hinders the promotion of parts management and packaging automation.

Purpose of the invention The present invention solves the above-mentioned conventional drawbacks, and aims to reduce the cost of packaging materials and simplify the packaging of the legs of an electric kotatsu and the protection of the heat generating part.

Structure of the Invention In order to achieve the above object, the packaging device for an electric kotatsu of the present invention is made of cardboard or the like, and has four outer side parts separated from each other, and two edges of each outer side face facing each other in the width direction. A bottom surface portion and a top surface portion that are connected to each other, an inner side surface portion that is formed on the top surface portion so as to face the outer surface portion and adjacent ones thereof are bent and connected to each other, and a joint that is connected to the bottom surface portion. and a joint part connected to the inner side surface part located at one inner end of the inner side surface part, and the mutually adjacent bottom surface parts and the upper surface parts are formed in a substantially V shape with a cut groove between the outer surface parts in between. Each bottom surface part and each top surface part are separated into parallelograms, and each bottom surface part is joined to each inner surface part by a joint part connected to the bottom surface part to form a sleeve shape, respectively. The four legs of the electric kotatsu are configured to be insertable into each leg separately, and the inner side surfaces at both ends are connected to each other by a connecting portion connected to the inner side surface located at the one end, so that the heating element of the electric kotatsu is heated. It is constructed so that it can be surrounded.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below based on the drawings.

In Fig. 1, 1a to 1d are outer surface parts, 2a to 1d are outer surface parts, and 2a to 1d are
2d, 3a to 3d are folding lines on both widthwise edges of the outer surface parts 1a to 1d, 4a to 4d are bottom parts connected via the folding lines 2a to 2d, and 5a to 5d are folding lines 3
Upper surface portions 7a to 7d connected via a to 3d
is an inner side face part connected to the upper face parts 5a to 5d via folding lines 6a to 6d, and faces the outer side faces 1a to 1d. 9a to 9d are joint parts connected to the bottom parts 4a to 4d via folding lines 8a to 8d; 10a;
10c is a folded line connecting mutually adjacent inner sidewalls 7a to 7d, 11 is a joint extending from the inner sidewall 7d located at one end via the folding line 10d, and 12a to 12c are the outer sidewalls 1a. ~1d
A cut groove is formed to separate the bottom surface portions 4a to 4d and the top surface portions 5a to 5d.
The grooves between 1d and 1d are parallel to the folding lines 10a to 10c, and the grooves are parallel to the folding lines 10a to 10c, and the grooves are parallel to the folding lines 10a to 10c, and are located between the bottom parts 4a to 4d and the top parts 5a to 5.
The kerf between d is inclined at an angle of 45 degrees in a substantially V shape, sandwiching the kerf between outer surface parts 1a to 1d, and the kerf between outer surface parts 4a to 4
d and the upper surface parts 5a to 5d form a parallelogram,
The whole is formed by punching out a flat corrugated sheet or the like. Note that the inner surface portion 7a fixed between the joint parts 9a to 9d and to the joint parts 9a to 9d
A concave fitting portion 17 is formed between 7d and 7d.

FIG. 2 shows inner side parts 7a to 7d and upper surface parts 5a to 5.
d, bend the outer surface parts 1a to 1d, the bottom parts 4a to 4d, and the joint parts 9a to 9d, respectively, and then fold the joint part 9a
-9d are joined to the ends of the inner side parts 7a-7d to form four independent sleeve-shaped containers, and from this state the folding lines 10a-
10d (see FIG. 3), and then, as shown in FIG. 4, the joint 11 is joined to the end of the inner side surface 7a, thereby forming a windmill-type device.
FIG. 5 shows the packaged state, and 13 is the leg of the electric kotatsu, 14 is a heating element, 15 is a frame, 16 is a crosspiece, and 18 is a fixture such as styrofoam. As shown in FIG. 5, the packaging device assembled as shown in FIG. is inserted. At this time, the upper end of the packaging device is slightly higher than the heating element 14 to provide pressure strength. The fitting parts 17 fit into the crosspieces 16, respectively, and in order to securely fix the legs 13, the fixing tool 18 is installed in one end of each sleeve-shaped container between the adjacent legs 13, 13. Set it up.

Effects of the invention The packaging device of the present invention can be implemented as described above, and it is easy to fold, improve storage efficiency, and is easy to assemble. This can be done using packaging materials, and the amount of packaging materials can be reduced, thereby reducing packaging material costs.
As for the material, in addition to cardboard as mentioned above, synthetic resin can also be used.
