【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing a corrugated board cushion according to a first embodiment of the present invention, and FIG. 2 is a view (a) of the corrugated board cushion viewed from the direction A in FIG. 1 (left side). FIG. 3 is a plan view of the corrugated board made from the corrugated cardboard shown in FIG. 1 (right side view). FIG. 4 and FIG. 4 are explanatory views for assembling the corrugated board cushioning body.

As shown in FIGS. 1 and 2, the corrugated cardboard cushioning body 10 of the present embodiment is formed by folding a single corrugated ball plate into a predetermined rectangular shape and stacking a plurality of layers. (Corresponding to the part) and fixed in one piece, and has a rectangular parallelepiped shape as a whole.

As described above, the corrugated cardboard cushioning body 10 is molded into a predetermined external shape as shown in FIG. 1. In this molding, corrugated cardboard punched into a shape as shown in FIG. The plate 11 is used. The corrugated board 11 is, for example, a double-sided corrugated board or a double-sided corrugated board in which a liner paper (not shown) and a corrugated core paper are bonded to each other.

As shown in FIG. 3, the corrugated board 11 has a valley fold line T1 formed along the central axis of symmetry, and the left and right portions divided by the valley fold line T1 are divided into two parts. The mountain crease lines T2 and T2 are formed so as to be divided into just half. As a result, the corrugated board 11 is formed with four flat plate portions P1 to P2 having the same rectangular shape by the valley fold lines T1 and the mountain fold lines T2 and T2, as shown in the figure. In this case, it is preferable in terms of strength and rigidity to set the eye direction of the corrugated ball used for the corrugated board 11 in a direction orthogonal to the valley fold line T1 and the mountain fold lines T2, T2. However, the present invention is not limited to this.

The valley fold line T1 is composed of intermittent linear punching lines 14a to 14c and connecting portions 14d and 14e formed therebetween. Further, between the end portion of the punched line, that is, between the punched line and the connecting portion, a linear small cut 22 having a predetermined length is formed in a direction orthogonal to the punched line. When bent along the valley fold line T1, the flat plate portions P2 and P3 are overlapped while bending the connection portions 14d and 14e. Here, an appropriate tensile stress is generated on the mountain fold side of the connecting portions 14d and 14e, and the elasticity of this portion causes the flat plate portions P2 and P3 to adhere to each other.

The mountain fold lines T2, T2 are composed of linear half-cut lines 16a to 16c and 18a to 18c which are intermittently applied. That is, in FIG. 3, the liner paper (not shown) on the back side in the drawing is left alone for cutting. When bent along the mountain fold lines T2 and T2, the flat plate portions P1 and P2 and P3 and P4 are overlapped while bending the liner paper.

Band portions 12, 12 are formed between the respective half-cutting lines 16a to 16c which are intermittently applied. The band portions 12 and 12 are formed by punching so as to straddle the mountain fold line T2 and extend in a direction orthogonal to the mountain fold line T2. Further, a locking bulge 12a is formed at the tip of the band portion 12. By forming the band portion 12 so as to straddle the mountain fold line T2, it is possible to prevent only the portion of the band portion 12 from protruding outward from the outer shape of the rectangular parallelepiped after the corrugated board cushion 10 is molded. In addition, the moment of the force that sandwiches the flat plate portions P1 to P4 due to the elasticity of the band portion 12 acts in a direction to bring the flat plate portions into close contact with each other, which is preferable. However, the present invention is not limited to this, and the band portion 12 may be formed by extending just from the mountain fold line T2.

On the other hand, fitting holes 24, 24 for fitting the band portions 12, 12 are respectively provided between the half cut lines 18 a to 18 c which are intermittently provided. It is formed at a position corresponding to when assembled. The fitting insertion holes 24, 24 are formed by punching so as to extend across the mountain fold line T2 in a direction orthogonal to the mountain fold line T2. Further, the corrugated board 11 is assembled with the engaging hole portions 24a, 24a, which are in communication with the fitting insertion holes 24, 24 and serve as engaging portions into which the engaging bulging portions 12a, 12a are fitted. It is formed at a position corresponding to the occasion.

The punching lines 14a to 14c, the half-cutting lines 16a to 16c, 18a to 18c, the band portions 12 and 12, the fitting holes 24 and 24, and the like are simultaneously processed by a press. As a result, it is formed.

As shown in FIG. 4, the corrugated board 11 is bent along the valley fold line T1 and the mountain fold lines T2 and T2, and the plurality of laminated flat plates are formed by bending the corrugated board 11 The band portion 12 is turned in such that the portions P1 to P4 are sandwiched from the side, and the locking bulging portion 12a at the tip end portion of the band portion 12 is fitted into the locking hole portion 24a. It is possible to obtain the corrugated cardboard-made shock absorber 10 that is integrally molded by locking it.

Here, the width dimensions of the band portions 12 and 12 and the width dimensions of the fitting insertion holes 24 and 24 are substantially the same, and the locking bulging portion 12a and the engaging portion are the same. Since the stop holes 24a are formed in substantially the same shape, they can be fitted tightly together and fixed integrally without an adhesive.

Next, the operation of this embodiment will be described. For example, when packing an article to be packed such as an electric product, first, the corrugated board 11 punched into the outer shape shown in FIG. 3 is bent to form the corrugated board cushion 10.

When this corrugated board cushion 10 is formed, it is valley-folded along the valley fold line T1 between the flat plate portions P2 and P3, and the space between the flat plate portions P1 and P2, and between P3 and P4. By mountain-folding along the mountain-folding lines T2 and T2 shown in FIG. As a result, when each of the rectangular flat plate portions P1 to P4 is pressed from the direction D in the drawing, the flat plate portions are in contact with the adjacent flat plate portions in a plane, and a plurality of the flat plate portions P1 to P4 are stacked to form a rectangular parallelepiped shape. .

Next, as shown in FIG. 4, the band portion 12 bundles and sandwiches the plurality of stacked flat plate portions P1 to P4, and the flat plate portions are arranged from below in the drawing. The band portion 12 is fitted into the fitting holes 24, 24 while being brought into contact with the side end portions of the portions P1 to P4, and is turned up in the figure.

Next, the locking bulging portion 12a at the tip of the band portion 12 is fitted into the locking hole portion 24a and locked. Thus, the step ball cushioning body 10 integrally formed as shown in FIG. 1 is completed.

As described above, since the adhesive is not used at the time of assembling, there is no adhesive applying step and no sticking step, and the adhesive does not need to be dried, so that the corrugated board cushioning body 10 is efficiently assembled in a short time. Therefore, the workability is significantly improved. Moreover, when the cardboard cushioning body 10 is transported before use, it can be a flat flat corrugated board 11 and can be transported without being bulky.

When the electric shock absorber 10 is used to pack an electric product, for example, the corrugated shock absorber 10 is appropriately prepared according to the type of the object to be packed and the transportation specification. Then, the package is completed by bringing it into contact with the end of the packaged object and storing it in an exterior case (not shown).

The corrugated cardboard cushioning body 10 housed in the outer case can be molded in accordance with the size of the outer case or the object to be packed, and thus can be tightly housed in the outer case without rattling. The shock-absorbing property is also improved, and the items to be packed are thus sufficiently protected.

Further, when the cardboard cushioning body 10 is used up after packaging, the entire corrugated cushioning body 10 can be recycled as waste paper, and can be incinerated as it is, or buried in soil or the like for disposal. However, it will be corroded and can be easily disposed of without any environmental health problems.
