Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a deployable foldable container. In particular, the present invention relates to a portable foldable container that can be instantly and easily formed into a plate shape when not in use, and can be immediately used as a container when not in use.

[0002]

2. Description of the Related Art As a conventional prefabricated container or box which can be repeatedly developed and assembled, a returnable cardboard box (actually, a box 63) provided with magic tape (trade name) as a locking member on a side plate and a flapper. No. 175016), a container provided with male and female hooks to make it attachable to and detachable from the superposition section (actual open flat 1-176024), and an assembly box provided with a removable adhesive on a part of the auxiliary plate (Japanese Patent Laid-Open No. -98847), and a folding box (actual Kaihei No. 7-6113) in which hooks are attached to both ends of each upper edge of four side surfaces continuous in an annular shape.

[0003]

However, in the conventional boxes and containers that can be unfolded and assembled, the unfolding and assembling can be repeated, but since the unfolding and assembling cannot be immediately performed, the storage and use are frequently repeated. In some cases, the assembly and deployment work is troublesome. Therefore, if there is a foldable container that can be instantly expanded into a plate when not in use, and that can be used immediately when in use, it is convenient to carry, and can be used for storing small items at hotels such as travel destinations, watching sports or outdoors. I thought that it could be used in many ways as a plate for food in.

The present invention has been made in order to solve such a problem. By providing the side plate starting means with an elastic function, the side plate rising means immediately becomes a compact plate shape during storage or carrying, and there is no touch during use. The purpose of the present invention is to provide a foldable container that immediately becomes a container shape.

[0005]

SUMMARY OF THE INVENTION According to the present invention, a side plate of a container can be simply and quickly bent and spread to make it into a plate shape when it is stored, and when used, the side plate of the container can be immediately raised without touching from an elastic material. The side plate start-up means is provided. As described above, the side plate rising means made of the elastic material can be immediately made into a plate shape or a container.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION A foldable container according to the present invention comprises a material plate body, a side plate adjacent to each side of a bottom plate via a fold line, and a fold line connected to the side plate on each side. A connecting plate is provided between the plates, a fold line extending from each corner of the bottom plate to the center of the connecting plate is provided, a side plate starting means mounting portion is provided at an outer edge portion between the side plate and the connecting plate, and is made of an elastic body. The side plate raising means is attached to the side plate raising means mounting portion. The side plate raising means may be any device as long as it exerts a force sufficient to raise the side plate when no force is applied from the outside and forms a plate shape when a force is applied from the outside. A rubber band is preferable as shown in the embodiment of FIG. Instead of a rubber band, a rubber cord having convex portions at both ends so that it can be attached to the side plate rising means attaching portion may be used. The side plate raising means mounting portion may be of any type as long as the side plate raising means does not come off, but a cutout, a notch, a groove or the like is preferable as in the later embodiment. The outer edges of the material plate body should have rounded corners to prevent other objects from scratching.

The side plate rising means mounting portion may be a groove provided in the connecting plate at the cut end. The side plate rising means mounting portion may be a groove provided in the side plate at the tip of the notch, and the side plate rising means may be one rubber band.

A side plate is continuously provided on each side of the bottom plate via a folding line, and a material plate body in which the side plate is separated at each corner of the bottom side and an elastic connecting plate as a separate side plate starting means are provided on the side plate. You may install in series. Since the connecting plate at this time may act as a spring, the elastic plate may be a bellows or corrugated shape, but a rubber plate is preferably attached. In addition, the connecting plate is made into a thin cloth or film that can be bent freely, and the side plate is provided with cuts and cuts, which are mounting parts for the side plate starting means,
The function can also be obtained by attaching side plate raising means such as a rubber band or a rubber cord to the side plate raising means mounting portion.

A side plate is continuously provided on each side of the bottom plate via a fold line, and an elastic connecting plate is integrally formed as a side plate starting means between the side plates via a fold line connected to the side plate. Good. Since this elastic connecting plate acts as a plate spring, it may have a bellows or corrugated shape, but it is preferable to make it thinner than other plate portions so that it has a rounded outside as in the embodiment shown later. Good.

The foldable container thus constructed is
When carrying it in a bag or bag, it is pressed from the back and front to form a plate, and when used, the side plate stands up and becomes a container shape simply by taking it out.

0 stands up and the container shape is maintained.

With the above-described structure, the folding container thus formed into a container shape can be pressed against the back and front of the folding container by applying a force,
Since the material plate main body 1a is expanded, the attached rubber bands 50, 51, 52, 53 extend to form a plate shape as shown in FIG. Then, from this plate-like state, it is possible to return to the container shape simply by removing the force pressing the back and front of the folding container.
In the first embodiment, the notch is provided as the side plate rising means mounting portion, but a notch is simply provided,
It is also possible to provide a groove or the like at the tip of the notch so that the rubber band is even more difficult to come off.

It may be provided on 8, 9, 10 or the connecting plates 19, 20, 21, 22. In this embodiment, a rubber band is used as the elastic body, but a rod-shaped rubber or the like having convex locking portions at both ends may be used, and a plate spring, a coil spring, a rubber cord ring, or the like may be used. . A rubber band is preferable in terms of cost and easiness of handling, but using a rubber cord or the like has an advantage that various colors can be used. From each corner 23, 24, 25, 26 of the bottom plate 2 to the connecting plate 19,
Fold lines 27, 28 extending in the central portions of 20, 21, 22
Although 29 and 30 are provided, the same effect can be obtained if each connecting plate is provided with two or more folding lines to form a bellows shape and each connecting plate is bendable and expandable. In this way, each connecting plate may be bendable and extendable. Alternatively, the connecting plate may be a separate body, and a foldable soft paper, cloth, plastic film, or the like may be attached.
