Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a packaging device for storing equipment such as washing machines.

(b) Prior Art A conventional example is shown in Japanese Utility Model Publication No. 59-22052, which will be explained based on FIGS. 3 and 4.

1 is a two-tub washing machine; 2 is a cardboard box for storing the main body of the washing machine; 3, 3 is a pair of upper cushioning bodies made of styrene foam for clamping and fixing both ends of the upper part of the main body of the washing machine 1; , press both ends of the lid 4 on the top of the washing machine 1. At the top of the lid 4,
An upper reinforcing body 6 is provided by bending a cardboard into an inverted U-shaped cross section and extending the ends thereof upward to form folded parts 5, 5, and further, both ends of the upper reinforcing body 6 are Recesses 7, 7 provided in the upper buffer bodies 3, 3
is fitted.

Thus, the outer flaps 8, 8 of the cardboard box 2
The insertion parts 9, 9 are formed by extending the tips of the upper reinforcing body 6 and bending them 90 degrees, and the insertion parts 9, 9 are inserted into the gaps 10, 9 formed by the folded parts 5, 5 of the upper reinforcing body 6. 10 to seal the top surface, and then tighten and fix with a band.

However, when this type of equipment is stored in a warehouse, it is likely that products will be stacked on top of each other, or that workers will work on the products. , the strength of the distal end portions of the insertion portions 9, 9 is relatively weaker than that of the bent base portions of the insertion portions 9, 9.
There is a risk of cracking and breaking from the center of the tip.

(c) Problems to be solved by the invention This invention prevents damage to cardboard boxes in packaging equipment.

(d) Means for solving the problem The packaging device of the present invention consists of a cardboard box for storing the device body, an upper buffer body disposed at both ends of the upper part of the device body, and a cardboard box installed between the upper buffer bodies. By bending the tip of the inner flap of the cardboard box, an insertion part is formed into the gap connected to the upper reinforcement part, and an appropriate cut is made at the bent base of the insertion part. It has a notch.

(e) Effect: That is, by providing the notch, the insertion portion becomes more flexible, and the pressure from the top side is accordingly dispersed.

(F) Embodiment An embodiment of the present invention will be described based on FIGS. 1 and 2. However, the same reference numerals are given to the same parts as in the conventional example, and the explanation is omitted.

11 is a cardboard box that stores the washing machine 1;
12, 12 is the outer flap of the cardboard box; 13;
13 is the inner flap. the inner flap 13;
13 has insertion portions 9, 9 formed by bending the distal end portions by 90 degrees. Furthermore, 14,1
Reference numeral 4 denotes a rectangular notch formed by cutting out the bent base of the insertion portions 9, 9.

Now, 3 and 3 are a pair of upper buffer bodies, 6 is an upper reinforcement body installed between the upper buffer bodies 3 and 3,
In the case of this embodiment, the upper reinforcement body 6 is not provided with the folded parts 5, 5, and therefore the insertion parts 9, 9 are inserted into the recesses 7 provided in the upper buffer bodies 3, 3. 7 and the side walls 6a, 6a of the upper reinforcing body 6 and are inserted and held in the gaps 15, 15.

Then, the washing machine 1 is stored in the cardboard box 11, the upper cushioning bodies 3, 3 and the upper reinforcing body 6 are placed, and the insertion parts 9 of the inner flaps 13,
9 is inserted into the gaps 15, 15, the top surface is covered with the outer flaps 12, 12, and then tightened with a band or the like to complete the sealing.

At this time, the length of the insertion parts 9, 9 is set so that there is a gap of about 1 cm with respect to the lid body 4,
A load is applied from above, and after the insertion parts 9, 9 are bent to some extent, their tips are brought into contact. That is, if they are brought into contact from the beginning, the degree of freedom in which the insertion parts 9, 9 can bend will be reduced, and the insertion parts 9 will be directly subjected to pressure accordingly.

Therefore, when pressure such as a load is applied from the top side, this pressure is not directly transmitted to the insertion portions 9, 9 due to the presence of the notches 14, and moreover, the insertion portions 9, 9 themselves are not bent to some extent. Therefore, the pressure is buffered, and the insertion portions 9, 9 (particularly the tips) are less likely to be damaged. In the experiment, the dimensions A×C of the notches 14, 14 were determined as A=
By setting 1/2W to 2/3Wcm and C=1 to 2cm, the bending structure of the insertion portions 9 and 9 is optimized, and an improvement in strength of 20 to 40 kg compared to the conventional method has been observed. Ta.

In addition, when this embodiment is adopted for packaging a nearly square device such as a fully automatic washing machine, both the inner flap and outer flap meet at the center, so the inner flap must be extended to form a separate insertion section. There is no need to install it, just bend the tip of the current inner flap.

Furthermore, if a ruled line is provided at the bending location, work efficiency will be further improved.

(g) Effects of the invention Since the packaging device of the invention has a notch at the bending base of the insertion part, the insertion part has a greater degree of freedom to bend even when pressure is applied from above, and this pressure can be buffered. can do. Therefore, it is possible to prevent damage to the insertion portion and, by extension, the cardboard box.
