However, in the above-mentioned conventional construction, in order to increase the size of the washing machine and to improve the ease of use, the size of the laundry entrance 3 has been increased, and the buffer 4 integrally formed of polystyrene foam has been developed. And the amount of styrofoam used increases, so that disposal after use is difficult, and bulky storage space is required.

Although styrofoam can be regenerated, there are also quality problems such as the incorporation of dust and the like adhered by the action of static electricity, and the incorporation of materials whose strength has deteriorated due to aging, and further recycling. Recovery, recycling equipment, recycling technology, etc., and it is not easy to recycle.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned conventional problems, and an object of the present invention is to provide a cushioning device for packaging made of cardboard which is effective with a small amount of material and is easy to reuse.

[0007]

In order to achieve this object, in a packaging shock absorber according to the present invention, a support member for buffering and fixing a washing tub is made of corrugated cardboard. The flap provided on the upper part of the supporting member fitted from above is bent to the left and right, and the fitting groove provided on this flap is combined with the notch of the other supporting member to form an X-shape. Further, the supporting member is disposed in an X-shape on the cover of the upper opening of the washing machine, and the portion that fits into the laundry entrance and the upper opening of the washing tub has a small waveform.

[0008]

According to this structure, the washing tub arranged swingably in the outer box receives an impact force due to vibrations caused by handling the cargo during distribution, but the flap provided on the upper portion of the support member has another function. Is fitted into the notch of the support member, so that it can be prevented from rotating around the crossed part, the shape of the buffer can be maintained as it is, and the washing tub is It is intended to prevent dents from being generated by colliding inward.

The outer periphery of two supporting members which are arranged in an X-shape on the cover of the upper opening of the washing machine and which intersects the impact force on the lower side (twill) which is most frequently generated in handling the washing machine. It is supported by the surface, and can distribute the received impact force. In addition, since the portion that fits into the input port and the upper opening of the washing tub has a small corrugated shape, the contact portion has a buffering effect and can prevent scratches.

Further, since the flap provided at the upper portion of the support member is disposed below the center of the lid of the washing machine, even if a load is received from above the lid, the flap is supported from below and the lid is cracked or deformed. Can be prevented. By using the rigid cardboard as the buffer as described above, the material used can be reduced, and it can be easily reused after use.

This will be described with reference to FIG.

FIG. 1 shows support members 5, 6 made of cardboard.
Shows a buffer body for buffer-fixing the washing tub by combining. The support member 5 has a groove 7 and a folded line 8 which are interdigitated and fitted substantially at the center, and forms flaps 9 and 10 on the left and right. The flaps 9 and 10 are provided with fitting grooves 11 and 12, respectively, and further have a cut 13 and a folding line 14.

The support member 6 has a folding line 15 at the center,
The fitting groove 16 and the notch 1 have substantially the same shape on the left and right.
7 are formed. The groove 7 and the fitting groove 16 are
The support members 5 and 6 are fitted in a state of being folded back at the folding lines 8 and 15. The notch 17 is fitted to the deepest part of the fitting grooves 11 and 12 of the flaps 9 and 10 of the support member 5.

The outer peripheral shape of the support members 5 and 6 in a cross-fitted state is formed in a shape substantially similar to the shape of the laundry doorway 3, and the lower outer periphery thereof has an upper opening, an upper end, and a lower end of the washing tub. The inner peripheral surface is fitted. In addition, this outer peripheral shape is formed so that a contact portion with the fitting surface has a small waveform 18.

With reference to FIGS. 2 and 4, a description will be given of how the buffer having the above structure is used as a buffer.
