Description

[Detailed Description of the Invention] Most of the conventional cushioning materials for packaging have been made of foamed polystyrene resin, but the market price of this material has soared, and the problem of waste pollution has also arisen.

This project improves the existing problems as described above, and allows this type of shock absorber to be integrally molded from a single piece of cardboard, for example, without reducing the shock absorbing effect.In addition, it is possible to create a packaging device that allows the material to be reused. This is what we are trying to provide.

An embodiment of the present invention will be described below.

That is, in the figure, 1 is a packaged object A such as a ventilation fan, for example.
The insertion opening 5 of the cylindrical main body frame 7 is located in the center, and the oil receiver on the upper part forms a mounting part for the flange part 11 consisting of a ring. The leg plate portions 3 which form the leg portions 12 at their ends are reinforcing plate portions each extending from the center of the end edge of these leg plate portions 2 and provided across the inside of the leg portions to serve to reinforce the leg portions 12. is the third
As shown in the developed view of the figure, it is made of a single cardboard buffer plate, and when inserted into the outer box 8 becomes the first buffer body B shown in the figure.

Reference numeral 4 denotes a locking hole provided in the base plate portion 1 so as to surround the insertion opening 5, and reference numeral 13 denotes a locking protrusion provided on both sides of the final end edge of each of the leg plate portions 2. As shown in FIG. In the formed state of the buffer body B, it engages with the locking hole 4 as shown in the figure, and serves to maintain the shape of each leg portion 12.

6 in the third diagram indicates the fold line at which the leg portion 12 is formed, 9°1
0 is the opening flap of the outer box 8, and C in the first diagram is a cardboard buffer plate that pairs with the first buffer B when the packaged object A is stored in the outer box 8. When housed in the outer box 8, the second shock absorber serves to press the flange 11 onto the base plate 1 as shown in the figure.

Since the present invention is constructed as described above, it is extremely easy to manufacture and assemble the buffer for holding the packaged object A.
Furthermore, compared to conventional foamed polystyrene resin products, it is less expensive and is made of recyclable, non-polluting materials, so it has the advantage of not causing any problems in this regard.

Furthermore, by engaging the locking protrusion with the locking hole, a rectangular cylindrical leg is formed in which the engagement position is located at the inner corner, and the reinforcing plate moves inside the leg in a diagonal direction from the inner corner. Since the reinforcing plate part applies force in the direction of inserting the locking protrusion into the locking hole, the locking protrusion does not easily come off from the locking hole, and the leg part is maintained. It has the unique effect of being shaped.

[Brief explanation of the drawing]

FIG. 1 is a plan view of an outer box in an open state showing an embodiment of this invention, FIG. 2 is an enlarged perspective view showing a first buffer, and FIG. 3 is a developed view of the structure shown in FIG. In addition, the same reference numerals in the figures indicate the same parts, 1 is the base plate part, 2 is the leg plate part, 3 is the reinforcing plate part, 5 is the insertion slot, 8 is the outer box, 11 is the collar part, 12 is the leg part, and A is the part. The object to be packaged, B is the first buffer, C
indicates the second buffer.

Claims (1)

[Scope of utility model registration request] In a packaging device that accommodates a packaged object having a flange in a sandwiched state in an outer box between first and second shock absorbers, the first shock absorber is inserted into a single cardboard board and the packaged object is inserted. A plywood part with an insertion opening and a locking hole formed thereon, and a mounting part for the flange part, a leg plate part connected to both ends of this plywood part, and the above part formed by cutting out a corner part. A reinforcing plate portion extending from the center of the edge of the leg plate portion and a locking protrusion projecting from both sides of the edge of the leg plate portion and engaging with the locking hole are provided, the leg plate portion and the reinforcing plate portion are bent, and the locking plate portion is bent. By engaging the projecting piece with the locking hole, a rectangular cylindrical leg part is formed in which the engagement position is located at the inner corner part, and the reinforcing plate part is located inside the leg part in a diagonal direction from the inner corner part. A packaging device characterized by being formed so as to cross an inner corner.
