Description

The present invention relates to, for example, a packaging cushioning material that is stored in an outer box together with a bottle body and cushions an impact applied to the bottle body.

Conventionally, when shipping a glass bottle consisting of a so-called one-box bottle filled with sake etc., the glass bottle may be broken by an external impact if it is left as it is, so it is cushioned by a packaging cushioning material so that it will not be broken by an impact during distribution. I try to do it.

For example, Patent Document 1 proposes a packaging cushioning material having a structure in which a plurality of corrugated cardboard sheets are bonded together with an adhesive to form a fitting hole into which the bottom of the bottle can be fitted.
Further, in Patent Document 2, a plurality of flat plates are serially provided so as to be bendable by 180 °, and an insertion hole whose diameter changes sequentially according to the taper of the bottle body is arranged and bored in each flat plate. Cushioning materials have been proposed.
Furthermore, in Patent Document 3, side plates are continuously provided around overlapping substrates to form a box shape, and two substrates are used as a cushioning material for a bottle in which a bent piece extending from an edge of the side plates is bent inward. Is connected via a connecting piece formed by cutting from one side of one of the substrates, and the side plate and the bent piece are sequentially extended from the opposite end edge of each set of the substrates, and the boundary between the one substrate and the connecting piece. The crease line of No. 1 is assumed to extend diagonally from the corner of this substrate, and the crease line at the boundary between the other substrate and the connecting piece is bent in the direction opposite to the other crease line, and the substrates are 90 ° to each other. A packaging cushioning material having a twisted and stacked structure has been proposed.

A plurality of outer plate portions that abut on the peripheral side wall of the outer box in a state of being continuously provided via a curved line and stored in the outer box, and a plurality of inner plate portions located between two adjacent outer plate portions. The inner plate portion is provided so as to be bendable by a second folding curve formed on the bottom plate portion so as to extend in a direction intersecting the first folding curve, and each of the two adjacent outer plate portions. The above-mentioned problem is solved by making the structure separably provided through a cut line.

According to the packaging cushioning material of the invention according to claim 1, a cushioning function against an impact from the peripheral surface side or the bottom surface side of the bottle body can be obtained by the action of the inner plate portion, so that the packaging buffer material has a simple structure. The bottle body can be reliably protected from external impact.
Further, when assembling the packaging cushioning material, it is only necessary to lightly bend the inner plate portion and the outer plate portion, so that the packaging cushioning material can be assembled extremely easily with little deformation during assembly, and the corrugated cardboard sheets are stacked and bonded together. It is possible to reduce the work cost and the material cost as compared with the packaging cushioning material of the structure.

According to the second aspect of the present invention, a double buffer structure is formed in which the outer plate portion and the inner plate portion cooperate with each other to reduce the impact from the peripheral surface side, so that the bottle body is reliably protected. It becomes possible to do.

FIG. 5 is a cross-sectional view schematically showing a state in which the packaging cushioning material shown in FIG. 1 is housed in an outer box together with a bottle body.

The packaging cushioning material of the present invention is stored in an outer box together with the bottle body to cushion the impact applied to the bottle body, and is used as a cushioning material for the bottom of the bottle body.
Examples of the bottle body include a glass bottle filled with sake and the like, a wine bottle and a glass bottle of other Western liquor, but the type of bottle body is not particularly limited, and ceramics and seto products are not particularly limited. It may be various bottle bodies such as a vase made of. Further, the cross-sectional shape of the bottom portion of the bottle body is not particularly limited, and may be any of a circular shape, a rectangular shape, and other shapes. Furthermore, the size of the bottle body is not particularly limited, and it is possible to support various sizes of bottle bodies by appropriately changing the size of the blank material.
As the outer box, for example, a box formed by bending various paper materials such as corrugated cardboard and cardboard so as to form a rectangular parallelepiped can be used.

The packaging buffer member 100 according to the present invention is formed of a single blank material, and as shown in FIG. 1, each of a substantially rectangular bottom plate portion 110 on which a bottle body is placed and four sides of the bottom plate portion 110 are placed. It has four outer plate portions 120 connected to each other via the first folding curve L1 and four inner plate portions 130 located between two adjacent outer plate portions 120. A circular opening 111 is formed in the central portion of the bottom plate portion 110.

The packaging cushioning material 100 of the present embodiment is made of, for example, corrugated cardboard, but a sheet member other than corrugated cardboard, such as paper or resin, may be used as long as it has cushioning properties.
In addition, each of the first folding curves L1 is a sheet-shaped blank material with creases in advance and a notch that does not reach the thickness, in consideration of workability, strength, and cushioning property. It may be anything such as a perforated one.

The inner plate portion 130 is separably connected to the two adjacent outer plate portions 120 via the cut line C1 and is bent at the second folding curve L2 formed in the plane region of the bottom plate portion 110. It is provided as possible. The second folding curve L2 is provided at a position where the inner plate portion 130 comes into contact with the bottle body when the inner plate portion 130 is bent.
The cut line C1 is formed so as to extend inward beyond the first fold curve L1, and extends in a direction in which the second fold curve L2 intersects the first fold curve L1 at the end position of the cut line C1. It is provided as follows.

The packaging cushioning material 100 is manufactured, for example, by punching a piece of corrugated cardboard with a punching machine, and as shown in FIG. 2, the four inner plate portions 130 are bent along the second folding curve L2 and the four outer plate portions are bent. It is assembled by bending 120 along the first folding curve L1.
As described above, the packaging cushioning material 100 according to the present embodiment has little deformation at the time of assembly and can be assembled extremely easily, and moreover, the packaging cushioning material 100 does not need to be significantly deformed, and therefore has various plate thicknesses. , It is possible to correspond to the strength of the plate and the shape of the outer box. In addition, the material area required for punching one blank material is smaller than that of a packaging cushioning material having a structure in which corrugated cardboard sheets are stacked and bonded together, less base paper is wasted, and work costs and material costs are reduced. Can be reduced.

Then, as shown in FIG. 3, the packaging cushioning 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 packaging cushioning material 100 is placed in the outer box 150 together with the bottle body B. It is stored. In the state of being stored in the outer box 150, as shown in FIG. 4, the outer plate portion 120 is in contact with the peripheral side wall 151 of the outer box 150, and the inner surface of the inner plate portion 130 is in contact with the outer peripheral surface of the bottle body B. At the same time, both end portions on the outer surface come into contact with the inner surfaces of 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 body B are in contact with each other, but as shown in FIG. 4, between the inner surface of the outer plate portion 120 and the outer peripheral surface of the bottle body B.
