2. Description of the Related Art Many proposals have been made in the past for a prefabricated box. To give an example, (a) 59
-78220 "Assembly container", (b) Japanese Patent Laid-Open No. 7-2
No. 77328, "Assembled container made of foamed synthetic resin", (C)
There are Japanese Unexamined Patent Publication No. 7-232733, “Assembled Box”, (d) Japanese Unexamined Patent Publication No. 7-291279, “Wooden Box for Packaging”, and (e) Japanese Unexamined Patent Publication No. 11-59656, “Assembled Box”.

Among the above-mentioned publicly known examples, (a) is one in which four side walls are attached to a bottom plate via a hinge, raised, assembled and flattened by folding, and (b) also has four circumferences based on the bottom plate. Providing connected side plates, raising them to assemble,
It provides an assembled container that can be folded inward and flattened for easy assembly, folding, good workability, and a large volume reduction ratio. In addition, (C) is a flat pallet at the bottom of the assembly box, with grooves for allowing side plates to be erected on four sides, L-shaped side plates are erected and fixed by bars, and (D) is a side plate on the four sides of the bottom plate. Is installed so that the recesses and protrusions at the end of the side plate are joined together so that they cannot be seen from the outside. (E) is a foldable side wall plate connected around the bottom plate, The face plate is bent to fix the four side walls.

[0004]

However, in all of the above-mentioned known examples, the bottom plate is basically used to form the box body by vertically arranging the side plates from the four circumferences, and as shown in (a) and (b), the bottom plate is formed. It is possible to fold it from the
As shown in (c), you can install a side plate by providing a groove on the four circumferences,
As shown in (d), a fitting part that does not appear in the exterior is formed at the end of the four side plates, or as shown in (e), a top plate is provided and fixed at the upper end of the connected side wall. However, it takes a complicated structure and requires many steps for assembling. In addition, a hinge part that connects the bottom plate and the side plate is required,
There were some difficulties such as time-consuming fitting and fixing.

It is an object of the present invention to have a pair of L-shaped side walls and a bottom plate, and the pair of L-shaped side walls having the same shape are placed symmetrically.
It provides an assembly type box that can be easily assembled by fitting both ends with concave and convex, and inserting and inserting the bottom plate from the top of the side wall, and disassembling it to reduce the volume. It can be easily manufactured by in-mold foam molding using foamed synthetic resin, etc., has good transportation and storage efficiency, and can be reused. Is to provide a large prefabricated box.

[0006]

A first aspect of the present invention is directed to an L-shaped side wall formed by a thick foam synthetic resin, which has a partial or full-circumferential edge portion projecting downward inward at a right angle. The pair of L-shaped sidewalls are symmetrically placed and each end portion is approximately 45 degrees with respect to the inner surface of the sidewall. The bottom plate is fitted and inserted from the upper portion of the side wall onto the projecting edge portion, and the whole is fixed as a bottomed box body to provide an assembly type box.

In the second aspect of the invention, the fitting portions of the pair of L-shaped side wall end portions are relatively horizontally displaced and fitted together.

According to the third aspect of the invention, the fitting portion at the end of the L-shaped side wall is provided with a dividing line at the middle portion in the height direction for separating the male and female molds at the time of molding, and the cross section of the fitting portion is provided above and below the dividing line. The shapes were different.

(Operation) In the first invention, since it is composed of the pair of L-shaped side walls and the bottom plate, there are only three parts, and molding and assembly are easy.

The L-shaped side walls are made of a thick synthetic resin foam and are lightweight, and a pair of the L-shaped side walls are symmetrically placed and both ends thereof are fitted to the inner surface of the side walls at approximately 45 degrees. Thereby, the side wall is easily formed. The angle of about 45 degrees is such that the right-angled fitting portion does not pop off on both sides and separate when the bottom plate is fitted and inserted, and the angle is not limited to 45 degrees.

The bottom plate is sized so as to be inscribed in the formed side wall, and is fitted and inserted from the upper part of the side wall, and is placed on the projecting edge part of a part or the whole circumference which projects inward at a right angle below the side wall. With this, it is simply supported and fixed, and the whole is completed as a box with a bottom.

The bottom plate is not only placed on the projecting edge portion of the L-shaped side wall, but also when the engaging portion is provided and fitted, the side wall is prevented from fluctuating and further fixed.

In the second aspect of the invention, the pair of L-shaped side walls are placed symmetrically, and the fitting portions are shifted in the horizontal direction so that they can be fitted together. Therefore, it is possible to prevent vertical displacement of the side walls. became.

In the case where the fitting is carried out by shifting relatively in the horizontal direction, it is desirable that the fitting can be carried out by concavo-convex fitting in the direction of 45 degrees so that the fitting portion will not be easily separated and will not come off due to the force acting on the side wall. . It is not limited to only 45 degrees, but may be fitted with an inclination such that the fitting portion does not separate.

In the third aspect of the present invention, the fitting portion of the L-shaped side wall is provided with a dividing line in the middle portion in the height direction so as to have a male shape and a female shape having different shapes in the upper and lower directions. It facilitates formation and molding of the fitting part. The fitting portion is separated into a male type and a female type at the time of molding at the middle portion of the side wall and has different shapes. By using the fitting portions having different cross sections above and below the dividing line in this way, it is possible to prevent the side wall from being displaced in the vertical direction by the usual in-mold foam molding technique.

BEST MODE FOR CARRYING OUT THE INVENTION According to the present invention, three parts, that is, a pair of L-shaped side walls and a bottom plate, can be formed by molding with foamed synthetic resin, and a box body can be completed by simply assembling each part. It is a lightweight, easy-to-use assembly type box that is disassembled to reduce the volume during transportation, storage, or storage.

The pair of L-shaped side walls are placed symmetrically, and the ends are fitted and fixed from approximately 45 degrees by shifting them relatively horizontally, and the bottom plate is inserted from the upper part of the side walls to form an L-shaped side wall. The assembly-type box can be completed by being placed on the protruding edge portion of or fitted.

The fitting part is separated into a male type and a female type having different shapes with the dividing line as a boundary, and it is possible to prevent vertical deviation.
It can be easily molded by in-mold foam molding with foamed synthetic resin. Especially, since the side wall is an L-shaped side wall of the same shape, the structure of the mold is easy, and the molded L-shaped side wall is placed symmetrically, The parts may be fitted together.
