(Means for Solving the Problem) To achieve the above object, a container according to the present invention includes a first side wall panel, a second side wall panel, and a third side wall panel facing the second side wall panel. The fourth side wall panel facing the first side wall panel, the bottom panel, and the ceiling panel facing the bottom panel are made of a heat-insulating rigid material, and each of the peripheral side edges is made of the rigid material. A peripheral edge of the bottom panel and a lower edge of the first to fourth side wall panels, each edge member having an elastic packing on its abutment surface. The edge members on the upper edge of the fourth side wall panel and one side edge of the ceiling panel further have detachable hinged structure portions that engage with each other, and the edge members of the first to fourth side wall panels Vertical side edges and the first to third side wall panels The upper edge and the edge members at the peripheral side edges of the ceiling panel excluding the one side edge further have a structural portion that can be fastened via a fastening member that can be inserted and removed.

(Operation) According to the container of the present invention, the bottom panel (the panel located on the bottom surface in the standard use state of the container) has the hinged structure portions on the four peripheral side edges thereof, and the container stands upright. The hinged structure portion on the lower edge of the side wall panel that becomes a wall is rotatably engaged.

Thus, the side wall panel can be erected on the four circumference sides around the bottom panel to form a box-shaped body. At this time, the structure part which can be fastened to each vertical side edge of the side wall panel functions so as to integrally connect the adjacent vertical side edges via the fastening member.

One upper edge of the side wall panel formed in the box shape and one side edge of the ceiling panel are connected to each other by the hinge structure.

With this hinged function, after storing food etc. in the container, the ceiling panel is swiveled to cover over the box shape,
The structure part which can be fastened on the other side edge of the ceiling panel and the structure part which can be fastened on the upper side edge of each side wall panel (excluding the hinged structure part of the side wall panel) are fastened via a fastening member, Form a hexahedral box-shaped container. This means that the elastic packing on the abutting surface of each panel is pressed against each other to keep the inside of the container sealed, and the cushioning of the contact surface and "creeping
It works effectively to prevent the generation of sound.

(Embodiment) An embodiment of the container according to the present invention shown in the drawings will be described as follows.

FIG. 1 is a perspective view showing an embodiment of the present invention. The container body 1 is formed in a hexahedral box shape by joining the side edges of the six panels 2a to 2f. Panels 2a, 2c, 2e and 2f are side wall panels, panel 2b is bottom panel and panel 2d
Is a different name for convenience from the ceiling panel.

2 to 4 are cross-sectional views shown in FIG. 1, and as is clear from these drawings, each panel 2a to 2f has a heat insulating property as a common configuration. A plate member 3 made of a rigid material such as polypropylene foam, edge members 4A, 4B and 4C made of a rigid material such as an aluminum alloy integrally attached to the periphery of the plate member 3 and the edge members 4A, 4B and 4C. And an elastic packing 5 made of synthetic rubber, for example, made of synthetic rubber. In addition, the container body 1
As will be described later, the fastening member 6 is provided.

The edge members 4A, 4B, 4C have a common structure, and sandwich a side of the plate member 3 and fix it by riveting, and a holding part 32 that engages the packing 5.
Have and. The edge member 4A has a hinged structure portion 33A having a J-shaped cross section, which extends from the support portion 34 and detachably forms an engaging relationship with the edge member 4B. The edge member 4B has a hinge structure part 33B extending from the support part 34 and forming an engaging relationship while inscribed in the hinge structure part 33A. When the hinged structure portions 33A and 33B engaged with each other are not detachable from each other when the panels to which the respective edge members are attached form 90 ° (see FIG. 2) and when the panels form 180 ° The J-shaped openings face each other and can be separated. The edge member 4C erects a locking portion 33C having an L-shaped cross section from the support portion 34, and keeps the two panels at 90 ° to each other as shown in the figure.
When the edge members 4C of the book are arranged so as to face each other, the fastening members 6 having a substantially C-shaped or inverted C-shaped cross section are inserted into the walls while pressingly contacting the locking portions 33C, 33C facing each other as inner guide walls. It Such press-fitting is to manufacture the cross-sectional shape of the fastening member 6 in such a size that the distance between the engaging portions 33C, 33C facing each other, which function as the structure portion that can be fastened as described above, is slightly narrowed. And the opposing packings 5 help to make this press fit effective. As described above, with respect to the edge member, 4A is used as 4B and 4C is used as 4C so as to be opposed to each other.

FIG. 5 is an exploded development view showing an example of an arrangement relationship of the container body 1 with respect to each panel of these edge members at the time of assembling. However, the edge members are not limited to this arrangement, and the arrangement can be changed under the condition that their facing relationship is satisfied. Each edge member is normally provided over the entire length of each side edge of each panel, thereby ensuring a close joint between the opposite side edges over the entire length and realizing a sealed structure of the container body. Similarly, it is preferable to prepare a fastening member 6 described later according to the length of each panel side edge to be press fitted. However, one length may be divided into a plurality of pieces to prepare a short member. Also, when the container body 1 does not necessarily require close contact of the side edges, or when the container body is large and close contact of the entire length of the side edges is difficult, the above-mentioned hinged structure portion 33A, The length of 33B or the length of the fastening member 6 can be appropriately shortened.

With respect to the bottom panel 2b, they are fastened with each other centered around the butterfly straight structure portions.

Next, as shown in FIG. 7, the side edge panels 2a and 2c are arranged on the remaining side edges of the bottom panel 2b, and the hinged structure portions 33A and 33B are combined and engaged with each other as described above. Then, the side wall panels 2a and 2c are coupled to the bottom panel 2b with the hinge structure as the center so that they can be joined together.

Next, as shown in FIG. 8, the side wall panels 2a, 2b, 2c, 2
The vertical side edges of e and 2f are brought into contact with each other, and a pair of opposing locking portions 33
By using C as a guide wall and inserting a fastening member 6 for fastening them (see FIG. 4), a box-shaped body with an open ceiling is formed.

Further, as shown in FIG. 9, the hinged structure portion of the edge member 4B at the upper edge of the side wall panel 2c and the hinged structure portion of the edge member 4A at one side edge of the ceiling panel 2d are engaged with each other, When the panel 2d is swung around the hinge structure, the panel body 1 can be covered as a ceiling panel. As shown in FIGS. 2 and 3, the ceiling panel 2d and the side edges of the side wall panels 2a, 2e, 2f are fastened by fastening the respective locking portions 33C to each other by inserting the fastening members 6 into each other. All panels 2a to 2f
Can be integrally joined.

FIGS. 10 and 11 are enlarged views of the joined state of each panel. In the joined state of the panels 2a to 2f, the packings 5 on the abutting surfaces of the respective side edges are in pressure contact with each other, and the inside of the main body 1 is sealed. It is possible to open or disassemble the assembled container body 1 by pulling out the fastening member 6 without using a special tool.

As is clear from the above, by adopting the hinged structure of the present invention, the two types of panels can be easily pivotally joined to each other without requiring any other member, and The side edges that are not taken can be easily joined by adopting a fastening member, and the removal of this fastening member is a simple extraction operation that does not require a special tool, and therefore the container body It is extremely easy to open and disassemble the door.
