Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a cardboard cushioning material for cushioning and holding a panel-shaped product in an outer box.
[0002]
[Prior art]
For example, when transporting a liquid crystal panel used for a display of a personal computer or the like, a base-like bottom pad made of cardboard and a cross-shaped partition are inserted into the outer box, and the liquid crystal panel is stored in the partition frame. Then, packing is performed so as to prevent the movement of the liquid crystal panel in the outer box.
[0003]
[Problems to be solved by the invention]
However, the packaging as described above has a problem that the liquid crystal panel is not fixed and held, so that the protection from vibration and impact is not sufficient. There is also a problem that it takes time to set the bottom pad and the partition.
[0004]
Accordingly, an object of the present invention is to provide a corrugated cardboard cushioning material that can securely hold and cushion a product and is easy to assemble.
[0005]
[Means for Solving the Problems]
In order to solve the above-described problems, in the cushioning material according to the present invention, the inner surface plate that is sequentially connected to both sides of the bottom plate is erected, the upper surface plate, the outer surface plate, the lower surface plate, and the inner heavy plate are wound, and the inner heavy plate is Overlaid on the face plate, the bottom plate was levitated and supported by a cylindrical pillar member, the cut from the inner surface plate to the upper surface plate was recessed, and the product storage groove was formed by fitting into the long hole of the inner heavy plate .
[0006]
This cushioning material is easily assembled by simply folding a single corrugated cardboard sheet, and the product inserted into the product storage groove can be fixed in a suspended state, so that it has excellent cushioning properties.
[0007]
Further, when a bracing plate extending from the inner heavy plate is wound and its tip is brought into contact with the ridges of the outer surface plate and the lower surface plate, the column member is reinforced and hardly deformed.
[0008]
Further, when the base end portion of the cut band is engaged with the edge of the elongated hole, shape retention is improved, and assembly and setting to the outer box are further facilitated.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the accompanying drawings.
[0010]
In the cardboard sheet blank shown in FIG. 1, an inner surface plate 2, an upper surface plate 3, an outer surface plate 4, a lower surface plate 5, an inner weight plate 6 and a bracing plate 7 are sequentially arranged on both side edges of the bottom plate 1. 7, the insertion piece 8 is provided in the front edge, and the insertion hole 9 is provided in the ridge part of the outer surface board 4 and the lower surface board 5, respectively.
[0011]
The inner surface plate 2 and the upper surface plate 3 are each provided with a band 10, and the inner heavy plate 6 and the bracing plate 7 are each provided with five pairs of long holes 11, and the width of the long holes 11 is equal to the inner heavy plate 6 and the bracing plate. 7 is wide and narrows toward the base end, and an engagement protrusion 12 is provided at the base of the cut band 10 so that the amount of protrusion toward the bottom plate 1 increases.
[0012]
To assemble such a blank, as shown in FIG. 2, the inner plate 2 is raised from the bottom plate 1, the upper plate 3, the outer plate 4, the lower plate 5, the inner heavy plate 6 and the bracing plate 7 from the inner plate 2. Is formed to form the column member 13, and the cut band 10 is recessed to form the product storage groove 14.
[0013]
And the insertion piece 8 is inserted in the insertion hole 9, and the front-end | tip of the bracing board 7 is contact | abutted to the ridge part of the outer surface board 4 and the lower surface board 5, and as shown in FIG.3 and FIG.4, as shown in FIG. When the inner heavy plate 6 is overlapped with the inner surface plate 2 while being fitted into the long hole 11, a cushioning material is formed in which the bottom plate 1 is supported by the pillar member 13 in a floating manner.
[0014]
In this way, the cushioning material can be easily assembled by simply bending a single cardboard sheet, and at this time, the cut band 10 can be easily fitted into the elongated hole 11 due to the tapered shape of the elongated hole 11. .
[0015]
Further, in the assembled state, the column member 13 is reinforced by the bracing plate 7 and is not easily deformed, and the engagement protrusion 12 is engaged with the end edge of the elongated hole 11 so as to be retained, so that it can be easily moved to the outer box. Can be set to
[0016]
When the cushioning material is set in the outer box and the product P such as a liquid crystal panel is inserted into the product storage groove 14, the product P is fixed in a suspended state and is reliably protected from vibration and impact.
[0017]
In this cushioning material, the strength in each direction can be adjusted as appropriate by changing the material of the corrugated cardboard sheet or by appropriately changing the size of the column member 13 or the notch of the end edge of the product storage groove 14.
[0018]
【The invention's effect】
As described above, the cushioning material made of corrugated cardboard according to the present invention can be easily assembled by simply folding a single corrugated cardboard sheet, and the product inserted into the product storage groove can be fixed in a suspended state, so that it has excellent cushioning properties. It will be a thing.

Claims (1)

An inner surface plate 2, an upper surface plate 3, an outer surface plate 4, a lower surface plate 5, an inner weight plate 6 and a bracing plate 7 are sequentially arranged on both sides of the bottom plate 1, and the inner surface plate 2 is erected from the bottom plate 1. The upper surface plate 3 is moved outward from the upper end, the outer surface plate 4 is moved downward from the outer end of the upper surface plate 3, the lower surface plate 5 is moved inward from the lower end of the outer surface plate 4, and the inner heavy plate 6 is moved upward from the inner end of the lower surface plate 5. The bracing plate 7 is bent diagonally outward and downward from the upper end of the inner heavy plate 6 that overlaps the inner plate 2 so that the tip of the bracing plate 7 is brought into contact with the ridges of the outer plate 4 and the lower plate 5 and is wound up. The cylindrical column member 13 is formed by bending in such a manner that the bottom plate 1 is levitated and supported by the column member 13, and an elongated strip-shaped cut band 10 is formed between the cuts cut from the inner surface plate 2 to the upper surface plate 3. the strip 10 by depressing due to bending, by fitting the elongated hole 11 extending from the inner heavy plate 6 toward muscle交板7 to form a product receiving groove 14 Cardboard cushioning material.
