[Problems to be solved by the invention]
However, in this conventional example, since the unfolded component is a folded box that is simply folded from each fold line at a right angle and assembled, there is no component for preventing the floating of the rectangular base plate placed on the upper surface of the bottom plate, As the soft food such as decoration cake is temporarily fixed and the base plate stored in the folding box cannot be prevented from floating, the soft food in the soft food may be moved together with the base plate due to the swing of the folding box while the soft food is being taken home. Since it floats at random and collides with the inner surface of the upper plate of the folding box, the upper part of the soft food is greatly deformed, the appearance looks extremely bad, and there is an essential and big problem that it becomes unusable .
[0004]
An object of the present invention is to easily and surely and inexpensively prevent the floating of a rectangular base plate disposed on the upper surface of the bottom plate of a folding box in order to eliminate the problems of the conventional example.
[0005]
[Means for Solving the Problems]
The object of the present invention described above is to form insertion pieces through the fold lines on the outer sides of the square side plates connected to the opposite two sides of the square bottom plate through the fold lines, respectively. A rectangular upper plate and a rectangular rear plate are connected in series through a fold line, and four reinforcing pieces are connected in series on the opposing sides of the front plate and the rear plate, two fold lines respectively. In the folding box in which each of the elements is folded at right angles in the same direction from the fold line, and the edge of the rear plate is bonded to the bottom plate, the oblique sides are formed on both sides of each insertion piece, Folding pieces are connected to each of the four reinforcing pieces via folding lines, and the folding parts of the folding pieces are inserted into the reinforcing pieces against the rigidity of the side plates and the restoring elasticity of the folding line portions of the reinforcing pieces.
