Description

TECHNICAL FIELD The present invention relates to a packaging device provided with a cushioning material.

2. Description of the Related Art Generally, a packaging box is provided with a cushioning material such as foamed plastic to protect stored items from impact. However, if the cushioning material moves inside the packaging box, the intended cushioning effect cannot be obtained. Therefore, as shown in FIG. 6, when the cushioning material 1 is two pieces, the cushioning material 1 is bonded to the corrugated board 2. Further, when there is only one cushioning material, the cushioning material 3 is enlarged to fit the packaging box as shown in FIG.

Problems to be Solved by the Invention In the case of the one shown in FIG. 6, the corrugated board 2 is required and the bonding work is required, and the one shown in FIG. 7 requires the cushioning material 3 larger than necessary. However, all of them had a problem of cost increase.

The present invention has been made in consideration of the conventional problems described above, and provides a packaging device capable of simply and securely fixing a cushioning material without requiring a special member for fixing the cushioning material and without enlarging the shape of the cushioning material. The purpose is to do.

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention cuts and raises a side edge portion of a flap forming a bottom plate of a packaging box near a corner portion of an inner bottom of the packaging box, and an upper portion thereof. A cut and raised piece having locking projections protruding outward on both sides is erected, and a concave portion corresponding to the cut and raised piece is provided on the outer surface of the cushioning body made of foamed plastic so as to face the inner surface of the packaging box. Forming and forming small recesses for locking on both side walls of the recess, locking the projecting piece on the first wall and the second wall formed by the small recesses for locking, The cushion body is fixed to the packaging box by fitting one piece into the recess.

With the above configuration, the packaging device of the present invention can engage the protruding pieces of the cut-and-raised pieces that are erected from the flap with the first wall and the second wall, and prevent the cushioning body from rising upward. It is possible to prevent the cut-and-raised piece from coming off from the recess by the second wall while preventing it by the first wall, and the buffer body can be placed in the packaging box without using a special fixing member. It becomes possible to fix it.

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

In the figure, 4 is a packaging box made of corrugated cardboard, and its bottom plate is composed of four flaps 5, 6, 7, 8.
Of the above-mentioned flaps, a pair of cut-and-raised pieces 9 are formed on both sides of the corresponding flaps 5, 7, respectively. The cut-and-raised piece 9 has locking projections 10 on both sides of the upper portion. When the flaps 5, 6, 7, 8 are combined to form a bottom plate, the cut-and-raised pieces 9 are erected on the inner bottom portion of the packaging box 4 along the side plate at a position close to the corner portion. On the other hand, the cushioning body 11 made of foamed plastic is formed in a cubic shape as shown in FIG. 3, and has a recess 12 on the lower part of the outer surface facing the inner surface of the packaging box 4. A small recess 13 for locking is formed on the corresponding inner surface of the recess 12. Due to the molding relationship, the small recess 13 for locking is formed by boring the buffer body 11 and forming a recessed groove 14 inside thereof. The recess 12 is shaped so that the portion of the cut-and-raised piece 9 excluding the protruding piece 10 fits. The two cushions 11 are disposed on both sides of the inner bottom of the packaging box 4, and the main portion of the cut and raised piece 9 is recessed 12
And the protruding piece 10 for locking the cut-and-raised piece 9 is fitted into the small recess for locking.
By being fitted into 13, the projecting piece 10 engages with the first wall 13a formed in the buffer body 11 by the small recess 13 for locking and thereby the buffer body 1
It prevents the 1 from floating upward, and also prevents the second wall 13b.
By this, the projecting piece 10 can be prevented from coming off from the concave portion 12 of the buffer body 11, and the buffer body 11 can be fixed in the packaging box 4. The buffer 11 is fixed in the packaging box 4.

According to this configuration, the cushioning body 11 may be smaller than the packaging box 4, and the bonding work is not required to fix the cushioning body 11.
No special fixing board is required. Therefore, the packaging cost can be reduced.

EFFECTS OF THE INVENTION As described above, the packaging device of the present invention cuts and raises the side edge portion of the flap that forms the bottom plate of the packaging box near the corner of the inner bottom of the packaging box, and projects outward on both sides of the upper portion. The cut-and-raised piece having the locking projection is raised, and a recess corresponding to the cut-and-raised piece is formed on the outer surface of the cushioning body made of foamed plastic so as to face the inner surface of the packaging box. Locking small recesses are formed on both side walls of the, and the protruding piece is locked to the first wall and the second wall formed by the locking small recess, and the cut and raised piece is fitted into the recess. By fixing the cushioning body to the packaging box by the above, the protruding piece of the cut-and-raised piece can be engaged with the first wall to prevent the cushioning body from being lifted upward, and at the same time, the cutting wall is cut by the second wall. It is possible to prevent the lifting piece from coming out from the concave portion of the shock absorber and to securely fix the shock absorber in the packaging box. Wear.

Further, the second wall formed in the cushioning body can restrict the elastic reaction force of the cut and raised piece formed by bending the flap of the packaging box and hold it in the recessed portion, and the outside of the packaging box. Since the inner surfaces of the cushions face each other, the cut-and-raised pieces do not separate from the cushioning body due to vibration or shock during transportation, and the cushioning body can be fixed in the packaging box and the stored article can be easily taken out.

Moreover, since the second wall can be protected from the outside by the packaging box, the second wall is not damaged by vibration or shock during transportation, and the stored article can be safely protected with a simple structure. It is possible.
