Moreover, since the base body 1 can be designed to be thick except for the thin portion 3 at the upper edge, it is easy to secure the strength of the base body 1 .

A specific embodiment of the present invention will be described with reference to the drawings.

The container of this embodiment is composed of a base 1 which is foldable and has a rectangular frame shape in plan view when opened, and a container 2 integrally formed of a thin synthetic resin. The base body 1 and the container body 2 are assembled by accommodating the lower part of the container body 2 so as to be dropped and covering the upper edge of the base body 1 with the outer peripheral edge of the container body 2 from above (see FIG. 1). ~ see Figure 3).

The pedestal body 1 of this embodiment is composed of plate members 5 that are stacked. More specifically, the pedestal body 1 is a horizontally elongated strip of paper that is made by folding a hard cardboard with a thickness of about 1 mm in two so that the folded edge side is at the bottom and the folded edge side on the opposite side is at the top. It is composed of material 5 (plate material 5). The base body 1 may be made of synthetic resin.

Further, the paper material 5 is held in a folded state by fixing means such as adhesion, and both ends in the length direction of the paper material 5 are connected by connecting means to form a frame shape (annular shape). At the same time, the annular paper material 5 is bent at a plurality of points to form a rectangular frame shape in a plan view.

In addition, as means for connecting both ends of the paper material 5, for example, an adhesive margin is provided at both ends or one of the ends of the paper material 5, and both ends are glued via the adhesive margin. or a configuration in which both ends of the paper material 5 are adhered with an adhesive tape such as paper tape or vinyl tape (in this case, for example, as described later, both ends of the paper material 5 are attached to the outer surface of the paper material 5 when viewed from above). If a configuration cut at an angle of 45 degrees is adopted, the work of taping the 45-degree end faces of both ends to face each other can be easily performed.) can be adopted, and other connection means can be adopted. can also

In addition, an outer sheet 7 having functions such as waterproofness, durability, and decorativeness is pasted on at least the outer surface of the paper material 5 (cardboard) that constitutes the base body 1. Three predetermined portions are cut in a groove shape in the vertical direction leaving the exterior sheet 7, and the cut portion of the cardboard where only the exterior sheet 7 is left and the connecting portion of both ends of the paper material 5 are formed with folding edges that can be bent. 6. The pedestal 1 is configured to be foldable into a band plate shape as shown in FIG. 2, these four folded edges 6 form the corners of the rectangular pedestal body 1, as shown in FIG.

Two folding edges 6A existing on one diagonal line of the rectangular frame-shaped pedestal body 1 are formed by cutting the paper material 5 at the folding edges 6A into relatively wide vertical grooves. The two sides of the paper material 5 adjacent to the edge 6A are configured to be foldable in a direction of 90 degrees or more in plan view and a direction of 90 degrees or less in a plan view via the folding edge 6A.

Further, one of the two folded edges 6 existing on the other diagonal line of the rectangular frame-shaped pedestal body 1 (folded edge 6B which is a connection portion of both ends of the paper material 5) is not shown in detail, but this Both ends of the paper material 5 at the folding edge 6B are formed on the end surfaces having an angle of 45 degrees with respect to the outer surface of the paper material 5 in plan view. The two sides of the paper material 5 adjacent to the folding edge 6B form an angle of 90 degrees in a plan view when the 45-degree end surfaces adjacent to the two sides are brought into contact with each other. It is possible to bend the two sides of the paper material 5 adjacent to the folding edge 6B through the edge 6B in a direction that expands them to 90 degrees or more in a plan view, but bending them to 90 degrees or less in a plan view will result in a 45 degree angle between the ends. are configured to become difficult by colliding with each other.

A folding edge 6C located diagonally to the folding edge 6B is formed by cutting the paper material 5 at the folding edge 6C into a vertical groove narrower than the folding edge 6A. is cut into a shape having an angle of 90 degrees with respect to the outer surface of the paper material 5 in plan view. One edge of the paper material 5 adjacent to 6C is in contact with the other edge, or both edges are in contact with each other. It is possible to bend the two sides of the paper material 5 adjacent to the folding edge 6C in a direction that expands them at an angle of 90 degrees or more in a plan view. It is constructed such that one edge of the material 5 touches the other edge, or both edges touch each other, making it difficult.

That is, the folded edges 6B and 6C are adjacent to the folded edges 6B and 6C from the unfolded state of the base body 1 in which the angle between the two sides of the paper material 5 adjacent to the folded edges 6B and 6C is 90 degrees. The folding range is limited to about 90 degrees until the base body 1 is folded so that the angle formed by the two sides of the paper material 5 becomes 180 degrees. Therefore, when the pedestal body 1 in the unfolded state is folded, it can be folded only in the direction in which the angle formed by the two sides of the paper material 5 adjacent to the folding edges 6B and 6C is increased to 90 degrees or more. When the pedestal body 1 in the folded state is unfolded, when the angle formed by the two sides of the paper material 5 adjacent to the folded edges 6B and 6C becomes about 90 degrees in a plan view, it is folded in the direction of reducing the angle further. (so that the pedestal body 1 does not go beyond the state in which it has been unfolded into a square frame shape and is in a folded state again).

The folding edges 6B and 6C may have the same configuration as the folding edge 6A, the folding edge 6B may have the same configuration as the folding edge 6C, and the folding edge 6C may be folded. A configuration similar to that of the edge 6B may be adopted.

Further, the base body 1 is provided with a plate-like thin portion 3 on the upper edge.

Specifically, the position of the upper folded edge of the folded paper material 5 is shifted vertically (the folded edge of the outer part of the paper material 5 is shifted from the folded edge (upper end) of the inner part of the paper material 5). The entire periphery of the upper edge is formed as the thin portion 3 for one sheet of paper material 5, and the portion below the thin portion 3 is substantially paper. The strength is ensured because it has a thickness of two pieces of material 5.

In addition, the base body 1 is provided with the thin portion 3 on the entire periphery except for the corners of the upper edge. More specifically, corners (four corners) of the pedestal 1 are configured as thin portions 8 obtained by cutting the thin portions 3, and the illustrated thin portions 8 are formed by the thin portions 3 adjacent thereto. The end edge (cut edge) is cut so as to form an inclined edge that separates from the corner portion (the folded edge 6) of the base body 1 toward the upper side. The depth and width of the cutout portion 8 are set according to the size and shape of the engagement recessed portion 4 of the container body 2, which will be described later.

The container body 2 of this embodiment is made of a thin synthetic resin material such as polypropylene (PP), polystyrene (PS), polyethylene terephthalate (PET), etc. As shown in FIGS. It is a mold and is formed into a box body having a square shape in a plan view that is substantially the same as the outside shape of the base body 1 when it is unfolded. The shape of the container body 2 is not limited to this embodiment, and various shapes such as hexagonal, octagonal, drum-shaped, gourd-shaped, circular and deformed shapes thereof can be adopted in plan view. It is also possible to easily prepare the pedestal body 1 having a shape corresponding to the container body 2 having these various shapes.

In addition, the container body 2 has a flange-like protuberance on the entire periphery of the container body 2, and is integrally molded in a shape in which the entire circumference of the flange is recessed upward in the form of a groove. is configured as an engaging recess 4 into which the thin portion 3 of the base body 1 can be inserted and locked.

The engagement recess 4 is formed in the same rectangular frame shape as the base body 1 (thin portion 3) in a plan view, and the lower part of the container body 2 is dropped into the base body 1. The container body 2 is assembled to the base body 1 by inserting and locking the thin portion 3 existing on the substantially entire circumference of the upper edge of the base body 1 into substantially the entire circumference of the engaging recess 4 while housing the container body 2 in the present embodiment. An example container is constructed to complete. At this time, the container body 2 may be fixed to the base body 1 in an assembled state by, for example, applying an adhesive to the thin portion 3 .

Further, when the container body 2 is assembled to the base body 1, as described above, the corner portions of the base body 1 are the non-thickened portions 8 where the thin portions 3 do not exist. It is inserted and locked into two corners (four corners) of the body excluding the engaging recesses 4, thereby facilitating the work of assembling the container body 2 to the base body 1. As shown in FIG. That is, the container body 2 with the engaging recesses 4 integrally formed of synthetic resin is designed so that the engaging recesses 4 at the corners do not have a right-angled shape in a plan view but an R shape in consideration of the ease of removal at the time of demolding. However, when the thin portion 3 having a right angle in plan view is inserted and locked into the R-shaped engaging recess 4 at the corner, the thin portion 3 contacts and interferes with the engaging recess 4 at the corner. However, in this embodiment in which the corners of the pedestal 1 are the non-thickened portions 8, such an obstacle does not occur. do not have.

Further, the container bodies 2 are formed in a shape that allows a plurality of them to be stacked and nested. That is, the container of this embodiment is shipped in a state in which the pedestal 1 and the container 2 are separated. It can be transported or stored without it.

It should be noted that the present invention is not limited to this embodiment, and the specific configuration of each component can be appropriately designed.
