Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a nesting and stacking container having rotatable supports at opposite upper ends of a rectangular shape.

[0002]

2. Description of the Related Art Conventionally, the following types of containers are generally used for the containers used for transportation and storage of articles. That is, it is mainly made of plastic and can be nesting and stacking and has a simple shape container with a handle integrally provided on the main body, a folding container having a folding structure, and an upper container when stacking on the upper end of the opposite side wall. There is a so-called handle container with a support, which is provided with a rotatable support for bearing the load.

[0003] For example, in Japanese Utility Model Laid-Open No. 1-126933, the bottom surface of the basket is received at a position opposite to the upper edge of the basket by reversing and turning inward and outward of the basket and when it is projected into the basket. A basket with various receiving pieces is described.

Further, in Japanese Utility Model Laid-Open No. 4-60839, a support member bent in an L-shaped cross section is rotatably supported at the upper ends of the left and right outer surfaces, and the support member is engaged with an edge formed at the upper end of the side surface. There is described a storage case that can be stopped and that has an upper surface that appropriately protrudes toward the inside of the case.

Further, in Japanese Patent Laid-Open No. 5-77833,
On the open end face of the container body having an open end at the top,
A stacking container is described in which an inwardly rotatable adjusting member of a container body is provided, and after the inward rotation of the adjusting member, the opening end surface is formed to be smaller than the outer bottom surface of the container body.

[0006]

However, in each of the stacking containers described in Japanese Utility Model Laid-Open No. 1-126933, Japanese Utility Model Laid-Open No. 4-60839, and Japanese Unexamined Patent Publication No. 5-77833, each of them is different. In order to make the receiving piece, the supporting member, and the adjusting member rotatably provided at the end thereof rotatable, a shaft is provided at an end portion, and a bearing hole is provided at the main body side so as to be axially attached.

During stacking, the receiving piece, the supporting member, and the adjusting member are rotated inward to receive a load from the upper side, and the bearing and the side wall of the main body bear the load. .

Therefore, the bearing portion bears the total load from above, and at the same time, a rotational moment acts on these receiving piece, supporting member, and adjusting member to press the upper side wall of the container body from the side surface. When the containers are stacked in multiple stages, especially if they are made of plastic, even if there are reinforcements such as ribs, the side walls of the container body will deform outward and the adjustment member will be displaced to the left or right. There is a concern that it will not be balanced and will cause a load collapse.

Further, during repeated use, the bearing is loosened or the side wall is deformed due to the creep phenomenon of the plastic material, so that the original state cannot be restored even under no load.
Problems such as lack of stability in stacking will occur.

The present invention has been made in view of the above problems, and an object of the present invention is to solve these problems so that the bearing portion is not burdened during stacking. Another object of the present invention is to provide a container having a supporting portion having a structure capable of preventing deformation and the like without pressing the upper side wall of the container body from the side surface.
