Description

[Detailed explanation of the idea] (b) Industrial application fields The present invention relates to a packaging device.

(b) Prior Art A conventional example is shown in Japanese Utility Model Publication No. 55-27587, which will be explained based on FIGS. 6 and 7.

1 is a washing machine, in which an outer tub 3 is attached to a hanging rod 4 in a machine frame 2.
It is elastically suspended and supported. 5 is a case of a motor 6 fixed to the outer bottom surface of the outer tank 3; 7 is an inner tank installed in the machine frame 2; 8 is a cover for a clothes input port 9 formed at the upper end of the machine frame 2; This is the top lid.

Reference numeral 10 denotes an internal cushioning body made of styrofoam provided to prevent the outer tank 2 from shaking greatly during transportation, and is fitted into the upper end of the outer tanks 7 and 3 inside the clothes input port 9, and It has a stepped portion 10a that restricts upward movement of the outer tank 3, and is held down by the upper lid 8 from above. Reference numerals 11 and 12 designate upper cushioning bodies made of styrene foam that are disposed above the front and rear portions of the washing machine 1 and are formed to match the respective shapes. 13 is a bottom buffer, and a receiving box 14 with an open top made of cardboard.
and a cushioning material 15 made of foamed polystyrene arranged diagonally within the receiving box 14. The cushioning material 15 is formed with recesses 17 for supporting the legs 16 of the washing machine 1.

Then, the washing machine 1 is placed on the bottom cushioning body 13 (the legs 16 are fitted into the recesses 17), and the internal cushioning body 10 and the top cushioning body 11, After placing 12, cover 1 made of cardboard
At step 8, the product is wrapped and the packaging is completed.

However, in such a packaging device, since the bottom cushioning body 13 is composed of two parts, the receiving box 14 made of cardboard and the cushioning material 15 made of Styrofoam, the number of parts is large, the cost is high, and the assembly is difficult. The sex was also bad. Furthermore, the saucer 14 was sometimes dented or torn during transportation.

Therefore, in order to solve this problem,
Japanese Utility Model Publication No. 58-47011 discloses a structure in which the bottom cushioning body 13 is integrally molded from polystyrene foam.

However, in such a case, when the products are piled up during storage, the load is mainly applied to the part supported by the legs 16 of the bottom cushioning body 13, so this part deforms and the legs is sinking. On the other hand, since the outer tank 3 is only suspended within the machine frame 2, not much load is applied to the bottom cushioning body 13, and the outer tank 3 is reduced by the amount that the legs (the machine frame 2) sink. relatively raised, the internal buffer 1
In some cases, the upper cover 8 was pushed up through the 0, causing the upper buffer bodies 11 and 12 to be damaged and the cover 18 to be torn.

(c) Problems to be solved by the invention This invention improves the strength of the part of the bottom shock absorber that supports the legs of the equipment in equipment packaging equipment, without using any separate parts, and improves product storage. This reduces the deformation of the bottom cushioning body when

(d) Means for Solving the Problems The packaging device according to the present invention includes a bottom cushioning body that supports the bottom of the device during packaging, which is integrally molded from Styrofoam, and a leg portion of the device in the bottom cushioning body. The supporting area is molded with a smaller foaming rate than other areas.

(e) Effect: By reducing the foaming rate, the strength of the parts that support the legs is increased.

(F) Embodiments Examples of the present invention will be described based on the drawings.
However, the same reference numerals are used for the same parts as in the conventional example, and the explanation is omitted.

FIG. 2 shows a washing machine 19 with a water storage tank, in which a water storage tank 20 is installed in parallel with the washing machine 1. Reference numeral 21 denotes a control section of the washing machine with a water storage tank 1, which houses a control board 22 on which various electrical components are mounted.

This type of control board 22 is coated with a voltage-resistant insulating material or a moisture-resistant material after various electrical components are arranged. Among various electrical parts, resistors and capacitors are parts that can be coated with no change in performance even if they are covered with coating agents, but connectors for external connections, IC sockets, switches, etc. cannot be coated. This is a part that cannot be coated because it would be a problem if the agent adhered to the contacts or pin jack.

Therefore, in this embodiment, during the coating work, a bottomed box as shown in FIGS. A switch cover 23 having a shape is provided. The material thickness of the switch cover 23 is 0.05 to 0.1 mm at the bottom surface 23a;
The side surface 23b is 0.3 to 0.5 mm. Then, the switch cover 23 is placed on the control board 23, and as shown in FIG.
Then, break through the bottom surface 23a of the switch cover 23 and attach it to the mounting hole 25 of the board 22. and,
Coating treatment is performed using coating agent 26. By doing this, the depth switch 24 is protected from the coating agent 26 by the switching 23, and since the legs 24a of the depth switch 24 break through the bottom surface 23a of the switch cover 23, the legs 24a are attached to the switch cover 23 from the beginning. The sealing effect is higher than that of forming an insertion hole.

Now, 27 shown in FIG. 1 is the washing machine 1 with a water tank.
a bulging step 28 that serves as a bottom buffer when packing the washing machine 1 side and the water storage tank 20 side, and a recess 29 into which each leg 16 is inserted. . . . and the stepped portion 30 that supports the case 5 of the motor 6 are connected to a receiving box 31 made of styrofoam.
It is formed integrally with the

When molding the bottom buffer body 27, the foaming rate of the bulging step portions 28 and the recesses 29 is lower than that of other parts. Specifically, the foaming ratio in the shaded area in FIG. 1 is set to 33 to 40 times, and the foaming ratio in other parts is set to about 55 times. The lower the foaming rate, the higher the strength (hardening).

Incidentally, if the strength is simply to be increased, the foaming rate at all locations may be lowered, but this does not provide an appropriate cushioning effect. Therefore, it is necessary to increase the strength of the shaded portion where pressure is mainly applied when a load is applied from above as in this embodiment.

In addition to washing machines, items to be packed may include large appliances such as refrigerators and other items that are likely to be subjected to loads from above during product storage.

(g) Effects of the invention The packaging device of the invention increases the strength of this part by setting the foaming rate of the part of the bottom cushioning body that supports the legs of the equipment to be lower than that of other parts. Therefore, the deformation of the bottom shock absorber due to the load from above during product storage is reduced, and damage to the product including the packaging material due to deformation can be prevented.

Moreover, since the strength is increased without using a separate member, the cost is also low.
