Detailed Description of the Invention

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a collapsible container used for transporting various articles or materials such as foods and medicines.

2. Description of the Related Art Aluminum containers are used for transporting various articles such as foods and medicines because they are lightweight and hygienic. Conventionally, most aluminum containers are provided with front and rear panels, left and right panels, a bottom panel and a lid panel made of an aluminum plate, and these are integrally welded to form a box shape. However,
In the above-mentioned container, after the goods are stored inside the container and transported to the destination, it is forced to return the container as it is even when the container is empty, which leads to a decrease in transportation efficiency and a transportation cost. In addition, there is a problem that a large space is required as a storage place for the container, and the storage cost accompanying this is high. In recent years,
A foldable aluminum container is also known, but since the panel forming the container is an aluminum plate to which a frame member is attached, it is weak in strength, and there is a disadvantage that the contents are limited. An object of the present invention is to provide a container that is foldable and has excellent strength. In addition, in this specification, "aluminum" shall include both pure aluminum and an aluminum alloy.

Is not limited to this extruded profile (31), and may be other extruded profiles, and the number thereof may be plural.

Since the container according to the first aspect of the present invention is a foldable type, it can be folded and returned when the container is empty after it is housed and transported to the destination. Therefore, the transportation efficiency is good, the transportation cost is reduced, and it is not necessary to secure a wide space for storing the container, so that the storage cost can be reduced. In addition, front and rear panels, left and right panels and bottom panel,
Since it is composed of a plurality of aluminum horizontal hollow extruded shapes in which the adjacent edges are fitted in concavo-convex shape, it is lightweight and excellent in strength, so that there is no restriction on the contents and various Not only can it be used for physical distribution, but the size of the container can be easily changed simply by recombining the hollow extruded profiles forming each panel. In the container according to claim 2, since the front and rear panels are divided into two,
Facilitates assembly and folding of the container. In the container according to the third aspect, one set or a plurality of sets of front and rear shelf panels are attached to the inside, so that a relatively small contained item can be stably accommodated in a plurality of stages in the container. Further, the hooking portion to which the hook portion of the shelf panel is hooked can be formed only by providing an opening portion extending in the lengthwise direction on the inner side walls of the hollow extruded shape members in the left and right panels. The container according to claim 4, wherein, of the extruded profiles forming the upper and lower panels and the left and right panels of the front and rear panels or the front and rear panels divided into two parts, a handle is attached to the outer wall of any one of the hollow extruded profiles for each panel. Since the panel is provided, it is possible to easily lift each panel at the time of assembling and folding the container, thereby improving workability. Further, the handle can be formed only by providing an opening portion extending in the lengthwise direction on the outer wall of the hollow extruded shape member in each panel.
