JPS5940307Y2 - Corner pads for packaging - Google Patents

Description

[Detailed Description of the Invention] This invention relates to a corner pad that supports the corners of foldable cardboard packages.

This type of pad is disclosed in Japanese Utility Model Application Publication No. 50-85573.

This invention has a side line part on the surface of the cushion part using a spreadable material made of a single piece of cardboard, but since the height of the side edge part of the face of the cushion part is only the height of one piece of cardboard, There is a drawback that the corners of the packaged item cannot be sufficiently protected.

The purpose of this invention is to solve the above-mentioned problems and to provide a simple and foldable corner pad that can reliably and sufficiently protect the corners of the packaged object.

The basic groove of this invention is to create a rectangular cardboard box that can be folded into three equal parts, hang the bottom plate, plywood, and support plate from one end of the cardboard box to the other end, and then A bendable insertion piece was provided on the supporting plate near the side, and the support plate was bent onto the plywood, and the insertion piece was bent in a direction perpendicular to the plywood, and the insertion piece was connected to the end of the insertion piece. The wide part is inserted into a groove provided in the plywood, and the corner of the packaged item is brought into contact with the inside of the insert piece.

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

Figure 1 shows the developed state of this invention, in which a rectangular cardboard /I/1 is divided into three equal parts, and a certain length is hung from one end 3 of the longitudinal direction to the other end 15. A rectangular bottom plate 4 is provided depending on the width.

On the other side of the bottom plate 4, a rectangular base plate 5 having the same width as the bottom plate 4 is provided.

On the other side of the base plate 5, a rectangular support plate 6 having a width larger than that of the plywood 50 is provided.

A cut 2 is provided at the boundary between the bottom plate 4 and the base plate 5 to a depth that does not reach the back surface of the cardboard 1.

The back side of the bottom plate 4 is in contact with the back side of the base plate 5, and although it is not shown in the drawings so that it can be bent, the paper on the front surface of the corrugated board 10 and the liner R are cut, but the paper on the back side of the corrugated pole is not cut. A cut 2 is formed.

A groove 7 is provided in the base plate 5, spaced apart from the cut q by a fixed width A, parallel to the cut 2, and having a fixed length C and a width comparable to the thickness of the corrugated board 1.

A fold 13 is formed at the boundary between the base plate 5 and the support plate 6.

Then, a fold 8 with a constant length E is formed on the support plate 6 parallel to the fold 13 provided at the boundary between the base plate 5 and the support plate 6 at a constant width A from the other end 15 of the corrugated pole 1. formed, supporting plate 6
Two cuts 9 are formed from both ends of the fold 80 formed in the plywood 5 toward the base plate 5.
The line connecting the side edges and the above cuts 9 and cardboard/1/1
The insertion piece 10 is provided inside surrounded by the fold 8 on the other side end 15 side, and the width from the edge of the insertion piece 100 on the plywood 5 side to the fold 8 on the other side end 1 side of the cardboard 1 B is set constant, and an insertion part 11 with a constant width F is provided on the side of the insertion piece 100 and the plywood 5.
are installed in succession.

Then, a line from both ends of the insertion part 110 plywood 5 side to the fold 13 provided at the boundary between the base plate 5 and the support piece 6, the fold 13 at the boundary between the base plate 5 and the support plate 6, and the insertion part 110 plywood The portion surrounded by the edge on the 5th side is removed to form a void 12.

Furthermore, parallel to the fold 13 at the boundary between the base plate 5 and the support plate 6, from this fold 13 toward the other end 15 of the corrugated pole 1, a width B equal to the width 10 of the aforementioned insert piece 100 is provided. Hole 1 of support plate 6
Folds 14 are formed on both sides of 20.

In this embodiment, the bottom plate 4 and the base plate 5 are further connected, and when in use, the bottom plate 4 is bent and abutted against the lower surface of the base plate 5 with the cut 2 as the boundary, so that the bottom part is made of two pieces and the strength is increased. However, in the case of a packaged item that does not require an increase in strength, the bottom plate 4 may be removed.

Furthermore, the width F of the insertion part 110 of the insertion piece 10 is made larger than the thickness F of the corrugated board 1, and grooves 16 similar to the grooves 7 of the base plate 5 are formed symmetrically on the back surface of the bottom plate 4. , insertion part 1
1 may be inserted deeply into both grooves 7 and 16.

Furthermore, a bottom plate 17 having the same shape as the bottom plate 4 may be adhered to the back surface of the bottom plate 4 (see FIG. 2).

The fold 8 of the support plate 6 provided on the other end 15 side of the corrugated cardboard 1 is straight in the illustrated case, but if the shape of the corner T of the packaged object P is curved, for example, it may be curved or uneven. For those with uneven surfaces, it may be provided in an uneven manner.

Also, the cuts 9 on both sides of the insertion piece 100 are at the other end 1 of the cardboard 1.
Instead of being provided at right angles to the fold 8 on the side 5, it may be inclined to correspond to the inclined side surface S of the object to be packaged P.

In the above corrugated board 1, the bottom plate 4 is bent on the lower surface of the plywood 5 along the cut 2 provided at the boundary between the bottom plate 4 and the base plate 5, and the insert piece 10 and the insert piece 10 are provided on the other support plate 6. The insertion part 11 connected to the board 1 is vertically erected through the fold 8 provided on the other end 15 of the cardboard 1, and the support plate 6 is inserted into the fold at the boundary between the base plate 5 and the support plate 6. 13 and the fold 14 on both sides of the space 12 of the support plate 6 provided on the other side of the fold 13, and fold it onto the plywood 5 in an upright cross-sectional shape.
The insertion portion 11 is inserted into a groove T provided in the base plate 5.

Since this invention has the above configuration, it has the following advantages.

Folds are provided on both sides of the void in the support plate, and these folds are spaced a certain width from the crease at the boundary between the plywood and the support plate, and are matched to the width of the insert piece. be.

Therefore, when the insertion part of the insertion piece is inserted into the groove of the plywood, the width of both constitutes a constant height between the plywood and the support plate, so this height corresponds to the thickness of the corner of the packaged item. If you do this, you can place the corner of the packaged item on the plywood.

In addition, the corners of the packaged item are formed from the inside of the insert piece and the notches on both sides of the support plate, and from the crease between the plywood and the support plate to the other side of the fold. It is supported by the inner edge of the support plate on the side of the cavity leading to the eye.
