Description

[Detailed explanation of the idea] This idea concerns cases.

2. Description of the Related Art Conventionally, a case made of cardboard or other thick paper is provided with handle windows on both end walls for carrying the case.

In this case, since the end wall was formed from a piece of cardboard, there was a problem in that the upper edge of the hand window dug into the palm surface, causing the palm surface to feel damaged.

Therefore, a laminated piece with a hand window was provided,
Since the laminate piece was attached to the inner surface of the end wall so that the holder window of the end wall and the holder window of the bonded piece matched, it took a lot of work to paste and also increased the unit price. There were other drawbacks.

The purpose of this invention is to eliminate the above-mentioned drawbacks by making the upper edge of the handle window double when the product is sealed after being stuffed.

This invention includes a pair of end walls with hand windows and a pair of side walls that stand up from the four edges of a bottom wall made of thick paper such as corrugated cardboard, and that the opposite edges of the end walls and side walls are Connection is made by fixing protruding pieces that extend from the end wall or side wall, and the top wall is connected from the top edge of one side wall, and the top edge of the remaining side wall and the tip edge of the top wall are fixed. Furthermore, protruding walls extending from both ends of the top wall are overlapped and fixed to the end walls, and
To provide a case in which the upper edge of a hand window is doubled by the lower edge of a projecting wall.

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

In the figure, 1 is a bottom wall formed of thick paper such as cardboard, and the four edges of this bottom wall 1 are
A pair of end walls 2, 2 and a pair of side walls 3, 3 are provided, each standing upright and facing each other.

In addition, hand windows 4 are provided on both end walls 2, 2.

Furthermore, the side wall 3 on one side is provided with an end wall 2 on the remaining side.
A top wall 5 is provided which is secured to the upper edge of the.

To fix the end wall 2 and the top wall 5, in the case shown in the figure, a fixing piece 6 is provided on the upper edge of the side wall 3 and bonded to the inner surface of the tip edge of the top wall 5 with an adhesive. A fixing piece 6 may be provided on the holder.

Furthermore, projecting walls 7, 7 are provided at both end edges of the top wall 5, the lower edges of which are aligned with the upper edge of the hand window 4, and which are fixed to the end walls 2, 2 via an adhesive.

In the illustrated embodiment, the area of the top wall 5 is smaller than the area of the bottom wall 1, so that the side walls 3, 3 and the protruding walls 7, 7 are provided with fold lines 8 to prevent the side walls 3, 3 from being folded.
3 and the upper sides of the protruding walls 7, 7 are inclined.

In addition, since the end walls 2, 2 are fixed to the protruding walls 7, 7 by overlapping them, in the case shown in the figure, they are made lower than the side wall 3 to reduce the adhesion area, but the side walls 3 and the end wall 2 are made to have the same height. You can.

In the figure, reference numeral 9 denotes a notch provided at the upper part of the opposing edge of the side wall 3 and end wall 2, and this notch 9 allows a part of the products packed in the case to be exposed. 10
are protrusions that extend from the lower part of both side edges of both side walls 3, 3,
This projecting piece 10 is fixed to the inner surface of the end wall 2 via an adhesive.

As described above, according to the case according to this invention, when the upper edge of the side wall and the tip edge of the top wall are overlapped and the end wall and the protruding wall are overlapped and sealed by fixing, Since the upper edge of a certain hand window and the lower edge of the protruding wall are made to coincide with each other, the thickness of the upper edge of the hand window can be increased due to the double wall.

Therefore, when carrying the case, the upper edge of the hand window can be bitten into the palm face, and damage to the palm face due to biting can be alleviated, and the occurrence of cracks on the hand window can be prevented. can.
