An object of the present invention is to provide a cushioning material for packaging that can be produced economically.

The present invention is a packaging cushioning material which is housed in an outer box together with a bottle and which cushions the impact applied to the bottle, comprising a bottom plate on which the bottle is placed, and a first fold around the periphery of the bottom plate. A plurality of outer plate portions connected via a curve and abutting against the peripheral side wall of the outer case when stored in the outer case, and a plurality of inner plate portions positioned between two adjacent outer plate portions. and the inner plate portion is provided to be bendable along a second folding line formed in the bottom plate portion so as to extend in a direction intersecting the first folding line, and each of the two adjacent outer plate portions The above problem is solved by providing a configuration that is separable via the cut line.

According to the packaging cushioning material of the invention according to claim 1, it is possible to obtain a cushioning function against impacts from the peripheral surface side or the bottom side of the bottle by the action of the inner plate portion, so that although the structure is simple, It is possible to reliably protect the bottle body from impacts from the outside.
In addition, when assembling the cushioning material, it is only necessary to lightly bend the inner plate portion and the outer plate portion, so that the deformation at the time of assembling is small and it is possible to assemble it very easily. It is possible to reduce the work cost and material cost compared to the structured packaging cushioning material.

According to the second aspect of the present invention, the outer plate portion and the inner plate portion work together to form a double cushioning structure that mitigates the impact from the peripheral surface, thereby reliably protecting the bottle. It becomes possible to

It is a perspective view which shows roughly the packaging process of the bottle body using the packaging cushioning material shown in FIG. 1. It is a cross-sectional view which shows roughly the state which the packaging cushioning material shown in FIG. 1 was accommodated in the outer box with the bottle.

The packaging cushioning material of the present invention is housed in the outer box together with the bottle to cushion the impact applied to the bottle, and is used to cushion the bottom of the bottle.
Examples of the bottle body include a glass bottle filled with sake (1.8 liter bottle), a wine bottle, and a glass bottle of other foreign liquors. It may be various bottle bodies such as a vase made of. Also, the cross-sectional shape of the bottom of the bottle is not particularly limited, and may be circular, rectangular, or any other shape. Furthermore, the size of the bottle body is not particularly limited, and by appropriately changing the size of the blank material, bottles of various sizes can be handled.
For example, the outer box can be formed by folding various paper materials such as corrugated cardboard and cardboard into a rectangular parallelepiped shape.

The cushioning packaging member 100 according to the present invention is formed from one blank material, and as shown in FIG. It has four outer plate portions 120 connected to each other via a first folding line L1 and four inner plate portions 130 positioned between two adjacent outer plate portions 120 . A circular opening 111 is formed in the central portion of the bottom plate portion 110 .

The cushioning packaging material 100 of the present embodiment is made of cardboard, for example, but sheet members other than cardboard, such as paper and resin, may be used as long as cushioning properties can be obtained.
In addition, each of the first folding lines L1 is formed by pre-folding the sheet-like blank material, by making a notch that does not reach the thickness, or It may be of any type, such as a perforated type.

The inner plate portion 130 is connected to two adjacent outer plate portions 120 via a cut line C1 so as to be separable, and is bent at a second folding line L2 formed in the planar region of the bottom plate portion 110. provided as possible. The second folding line L2 is provided at a position where the inner plate portion 130 contacts the bottle body when the inner plate portion 130 is folded.
The score line C1 is formed to extend inward beyond the first folding line L1, and at the end position of the score line C1, the second folding line L2 extends in a direction intersecting the first folding line L1. is provided as follows.

The packaging cushioning material 100 is manufactured by punching out, for example, one sheet of corrugated cardboard with a punching machine. As shown in FIG. It is assembled by folding 120 along the first folding line L1.
In this way, the cushioning packaging material 100 according to the present embodiment can be assembled very easily with little deformation during assembly, and there is no need to greatly deform the cushioning packaging material 100, so various plate thicknesses can be used. , the strength of the plate, and the shape of the outer box. In addition, compared to packaging cushioning materials with a structure in which corrugated cardboard sheets are stacked and bonded together, the material area required for punching out one blank material can be reduced, and the amount of wasted base paper is small, resulting in work and material costs. can be reduced.

Then, as shown in FIG. 3, the buffer packaging material 100 is positioned at the opening of the outer box 150 and pushed into the outer box 150 by the bottle body B, so that the buffer packaging material 100 is placed inside the outer box 150 together with the bottle body B. be housed. In the state housed in the outer case 150, as shown in FIG. While in contact with each other, both side end portions of the outer surface abut against the inner surfaces of the two adjacent outer plate portions 120 facing the outer surface. At this time, it is desirable that the inner surface of the outer plate portion 120 and the outer peripheral surface of the bottle B are in contact with each other, but as shown in FIG. A gap S may be formed in .

As described above, the cushioning material 100 of this embodiment has a so-called double cushioning structure in which the outer plate portion 120 and the inner plate portion 130 work together to absorb the impact from the side wall 151 of the outer box 150. Can be configured. That is, the impact applied to the peripheral side wall 151 of the outer box 150 is buffered by the outer plate portion 120 of the packaging cushioning material 100 and is also buffered by the inner plate portion 130 abutting on the inner surface of the outer plate portion 120, so that the bottle body B can be reliably protected. In addition, since the outer plate portion 120 is not in contact with the bottle body B, it is possible to avoid direct transmission of the impact from the side of the peripheral wall 151 to the bottle body B via the outer plate portion 120. It is possible to achieve sufficient cushioning and protection against loads and impacts from the peripheral side wall 151 side.

As described above, one embodiment of the cushioning material for packaging according to the present invention has been described in detail. , various modifications are possible.
