Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hinge structure and an assembling container which can be freely assembled and deployed.

[0002]

2. Description of the Related Art As an accommodation box for frozen foods and the like, there is an assembly box integrally formed of styrene foam. In the assembly box, the plate members are connected by hinges so that assembly and deployment can be performed freely. The assembly box can be unfolded into a flat state, which is convenient for transportation.

[0003]

However, the above-mentioned conventional assembly box is easily bent at a thin hinge portion.
It bends during handling such as molding, releasing from the mold, refilling, and transport. For this reason, it is necessary to convert the bent portion to a planar state, and the handling becomes complicated. Further, when the bent portion is corrected, the hinge portion may be damaged such as a crack.

The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a hinge structure and an assembled container which do not bend during handling and are easy to handle.

[0005]

According to a first aspect of the present invention, there is provided a hinge structure in which plate members are connected by a hinge portion thinner than the plate member, wherein a side surface of the plate member and a hinge portion thinner than the plate member are connected. A groove is formed between the grooves.
The hinge structure is characterized in that an elastic connecting member for connecting the side surfaces of the plate member to each other is provided so that the groove portions are orthogonal to each other.

In the present invention, an elastic connecting member is provided in the groove between the plate members. The elastic connecting member connects the side surfaces of the plate member and reinforces the thin hinge portion. Therefore, it is possible to prevent the hinge portion from being bent at the time of molding, releasing from the mold, refilling, transporting, and the like. Therefore, it is easy to handle and workability is improved.

The elastic connecting member is formed so that the grooves between the plate members are orthogonal to each other. Therefore, when a force is applied to the plate member so that the hinge portion is bent toward the groove, the elastic connecting member is pressed by the side surface of the plate member and is compressed by the elastic force, so that the hinge portion is bent. When the bending force of the hinge portion is released, the force of the side surface of the plate member pressing the elastic connecting member is reduced, and the side surface of the plate member is pushed back by the elastic force of the elastic connecting member to return to the original flat state. As described above, according to the hinge structure of the present invention, the bending recovery can be freely performed.

Further, since the elastic connecting member is formed to be orthogonal to the groove, the elastic connecting member receives a pressing force in a direction perpendicular to the side surface of the plate member. For this reason, an excessive force is not easily applied to the elastic connecting member at the time of bending, and damage is small.

[0009] As in the second aspect of the present invention, it is preferable that the hinge structure is a foam molded body integrally molded including the elastic connecting member. This facilitates manufacture. Also, the elasticity of the elastic connecting member can be secured, and the hinge portion can be bent.

Preferably, the groove is a V-shaped cross section. Accordingly, the hinge can be flexibly deployed.

According to a fourth aspect of the present invention, the groove is a W-shaped groove having a projection provided at the center and a first parallel groove and a second parallel groove provided on both sides of the projection. A first elastic connecting member and a second elastic connecting member connect the side surfaces of the plate member to the first parallel groove and the second parallel groove so that the first parallel groove and the second parallel groove are orthogonal to each other. Preferably, a member is provided. Thereby, the bending force applied to the hinge portion can be dispersed, and the breakage of the hinge portion during bending can be suppressed.

It is preferable that the first elastic connecting member and the second elastic connecting member are alternately arranged with the protrusion interposed therebetween. If the first elastic connecting member and the second elastic connecting member are arranged on the same axis with the protrusion interposed therebetween, the repulsive force applied to the side surface of the plate member during bending increases. Therefore, a large pressing force is required to compress the first and second elastic connecting members. When the first elastic connecting member and the second elastic connecting member are alternately arranged with the protrusion interposed therebetween as in the present invention, the repulsive force received on the side surface of the plate member is reduced, and the first and second elastic connecting members are applied with a slight force. The connecting member can be compressed. The fact that the first elastic connecting member and the second elastic connecting member are arranged alternately means that both of them need not be arranged so as to overlap on the same axis. It may be arranged at a remote position.

Although one elastic connecting member may be provided in the groove, two or more elastic connecting members are preferably provided. Thereby, the effect of reinforcing the hinge portion is further improved. It is preferable that the elastic connection member has a wider joint portion with the side surface of the plate member than other portions. Thereby, the joining strength of the joining portion between the elastic connecting member and the plate member increases. When the groove is a W-shaped groove, the elastic connecting member preferably has a wider joint portion with the central protrusion than the other portions. Thereby, the joining strength of the joining portion between the elastic connecting member and the plate member increases.

According to the present invention, it is preferable that the upper end of the elastic connecting member is located at a position lower than the upper end of the plate member. If the upper end of the elastic connecting member is located at a position higher than or higher than the upper end of the plate member, the upper end of the elastic connecting member protrudes from between the plate members during bending, which may impair the appearance. Therefore, by setting the upper end of the elastic connecting member to a position lower than the upper end of the plate member, the elastic connecting member does not protrude at the time of bending.
It does not impair the appearance. The height difference between the upper end of the elastic connecting member and the upper end of the plate member is preferably such that the upper end of the elastic connecting member does not protrude from between the plate members during bending. Thereby, the appearance at the time of bending can be further improved.

The thickness of the hinge is preferably 0.1 to 1 mm. If it is less than 0.1 mm, the hinge may be easily damaged, and if it exceeds 1 mm, it may be difficult to bend.

According to a seventh aspect of the present invention, there is provided an assembly container having the hinge structure according to any one of the first to sixth aspects. When assembling the assembly container, a force is applied to the plate member so that the hinge portion is bent toward the groove opening. Release the bending force when deploying the assembled container. At this time, the elastic connecting member compresses and recovers in response to the application and release of the bending force. Therefore, according to this assembly container, assembly and deployment can be performed freely. In addition, since the elastic connecting member is formed so as to be orthogonal to the groove, it receives a pressing force in a direction perpendicular to the side surface of the plate member. Few. In the above-mentioned assembled container, the plate member is a member constituting the assembled container such as a bottom plate, a side plate, and a lid plate.
