INDUSTRIAL APPLICABILITY The present invention is capable of improving storage efficiency by folding a storage container used for transporting and moving various kinds of articles when the articles are not stored to fold the articles. The present invention relates to a folding container, and more particularly to a folding container in which a bent portion of a folding side plate is devised in shape.

[0002]

2. Description of the Related Art Conventionally, a folding container as shown in FIG. 5 has been used as a container for transporting all kinds of articles such as foods, pharmaceuticals, cosmetics and industrial parts. The folding container 11 is entirely made of a synthetic resin material, and a bending side plate 5 is rotatably interposed inward of the frame 3 on one of the opposite sides of the bottom plate 2 and the frame 3, and the other side of the frame 3 Side plates 4 which are rotatable inside the frame 3 are suspended from opposite sides of the frame 3.

By folding the folding side plate 5 inward with the side plate 4 flipped up, the folding container 11 is folded to a thickness including the frame 3 and the bottom plate 1. .

[0004]

However, in the conventional folding container 11 described above, the convex portion and the concave portion of the folding side plate 5 facing each other in the inside of the container are intricately engaged with each other and engaged with each other. Therefore, the end surfaces of the upper folding side plate portion 5 ₁ and the lower folding side plate portion 5 ₂ that face each other inside the container, which face each other at the bending portion of the folding side plate 5, are formed of a pattern of repeating stepwise right-and-left concavities and convexities that interlock with each other. Therefore, the boundary 6 between the upper bent side plate portion 5 ₁ and the lower bent side plate portion 5 ₂ has a pattern of repeating stepwise right-and-left irregularities.

Since the boundary 6 between the upper bent side plate portion 5 ₁ and the lower bent side plate portion 5 ₂ has a stepwise right and left concave and convex shape, when storing and taking out various articles in the folding container 11. However, there is a possibility that it may be caught on the convex corner of the boundary 6 to damage the article or the hand.

In addition, when the folding container 11 is used for storing food, it is necessary to wash the container at all times to keep it clean. However, if the boundary 6 is a stepwise right-angled concave-convex shape, a concave right-angled shape is used. Since it is difficult for the cleaning tool and the cleaning liquid to reach the internal corners, there is a possibility that stains that are unfavorable to food hygiene may remain.

Therefore, according to the present invention, there is no need to damage or damage the hand when storing or taking out the goods.
Moreover, it is an object of the present invention to provide a folding container that is convenient for cleaning without remaining dirt.

[0008]

In order to achieve the above-mentioned object, the folding container according to the present invention comprises a bottom plate, a frame body facing each other above the bottom plate, and one side of the frame body facing each other. A folding container comprising a folding side plate that is rotatably connected between the side and a side of a bottom plate facing each other and is bendable inward of the frame body, with a bending portion of the folding side plate as a boundary. It is characterized in that the one end of the bending side plate and the other end of the bending side plate facing each other inwardly of the inside of the container are formed in a corrugated shape to be combined with each other.

[0009]

[Function] A conventional right-angled concavo-convex shape is formed by combining the opposite end faces of the inner side of the container of one bending side plate part and the other bending side plate part facing each other at the bending part of the bending side plate with each other so as to mate with each other. Unlike borders, there is no risk of catching on the convex corners and damaging the stored items or injuring your hands, and because there is no concave right-angled inner angle where dirt easily remains, dirt does not remain Easy to wash.

It is sectional drawing which shows the standing state. still,
The same parts as those in the drawings used for the description of the conventional art are designated by the same reference numerals, and the description thereof will be omitted.

In the drawing, 1 is a folding container made of a synthetic resin material of the present invention, 2 is a bottom plate, 3 is a frame, 4 is a side plate, 5 is a bent part as a boundary, and the upper part is an upper bent side plate part 5 ₁ and a lower part. the portion with lower bent plate portion 5 _2, bent side plates engaged pivotably in such engagement portions of hinges formed at both ends, respectively (not shown), 6 is folded container 1 inside meander It is the boundary between the upper bent side plate portion 5 ₁ and the lower bent side plate portion 5 _{2 in the} part.

The end faces 5 ₁ a and 5 ₂ a of the upper bent side plate part 5 ₁ and the lower bent side plate part 5 ₂ facing each other in the bent part inside the container are formed in a corrugated shape so as to be combined with each other. The boundary 6 between the upper bent side plate portion 5 ₁ and the lower bent side plate portion 5 ₂ has a simple wavy shape.

At the outer portions of the corrugated boundary 6 between the upper bent side plate portion 5 ₁ and the lower bent side plate portion 5 ₂ , the convex portions 5 are formed, respectively.
One set or a plurality of sets (a and three sets in the case of the present embodiment) of the bag-shaped recess 5b are formed. Convex portion 5a and bag-shaped concave portion 5
When a plurality of sets of b are formed, as shown in FIG. 2, convex portions 5a and bag-shaped concave portions 5b are alternately formed on the upper bent side plate portion 5 ₁ and the lower bent side plate portion 5 ₂ and combined. A stronger engagement state can be obtained.

A projecting piece 5c is formed at a tip portion of a wall surface on the inner side of the container in the bag-shaped concave portion 5b in a direction substantially perpendicular to the bag-shaped concave portion 5b, and a base end portion of the convex portion 5a is formed. Forming a recess 5d for engaging the projecting piece 5c,
When the bent side plate 5 is erected, the protruding piece 5c and the recess 5d engage with each other.

When the bent side plate 5 that is bent is erected,
As shown in FIG. 3, the convex portion 5a of the upper bent side plate portion 5 ₁ slides while pressing the inner wall of the bag-shaped concave portion 5b of the lower bent side plate portion 5 ₂ outwardly while pressing it, and the convex portion 5a is formed into a bag. When passing the position where the inner wall of the concave portion 5b is most pushed out, the inner wall of the bag-shaped concave portion 5b exerts a spring property of pushing and urging in the direction of engaging the convex portion 5a, whereby, as shown in FIG. The convex portion 5a fits into the bag-shaped concave portion 5b.

As described above, when the convex portion 5a is fitted in the bag-shaped concave portion 5b, the convex portion 5a is interposed between the wall surfaces of the bag-shaped concave portion 5b facing each other. Even if lateral pressure is applied to 5, the convex portion 5a does not separate from the bag-shaped concave portion 5b.

[0017]

As described above in detail, according to the folding container of the present invention, one folding side plate portion and the other folding side plate portion, which face each other at the folding portion of the folding side plate, are formed so that the opposite end faces of the container are opposed to each other. Unlike the conventional boundary consisting of right-angled irregularities, the combination of corrugated shapes eliminates the possibility of catching on the convex corners and damaging the stored items or hand, and also makes it easier for stains to remain. By eliminating the right-angled inner angle of, the cleaning is facilitated without any stain remaining. Further, it has an excellent appearance even when compared with a conventional folding container having a boundary composed of right-angled irregularities.
