Claims (1)

[Claims for Utility Model Registration] (1) A pair of rectangular inclined panels with outer rib panels connected to their upper sides, and a pair of isosceles triangular inclined panels having hypotenuses of equal length to the side sides of the inclined panels. A paper container comprising: a horizontal body panel; an upper part of the main body is formed by combining the outer rib panels of the pair of inclined panels; and a closing part is provided at the bottom of the main body; A right triangular front folding panel with an inner rib panel connected to the short side narrowing the right angle is connected to the long side narrowing the right angle on each side of the pair of horizontal body panels. On each hypotenuse side, a rear folding panel in the shape of a right triangle is connected on the long side narrowing the right angle, and an inner rib panel is connected on the short side narrowing the right angle in a symmetrical shape with the front folding panel. In addition, the front folding panel and the rear folding panel are connected to each other on their respective oblique sides, and the pair of tilted panels are tilted to each other by folding the boundary lines of both folding panels inward. Each of the inner rib panels is sandwiched between the outer rib panels of each of the pair of inclined panels to form an overlapping portion, and the overlapping portion is bonded to form a laminated rib on the upper part of the inclined panel, thereby sealing the upper part. A paper container characterized by: (2) When the rear folding panel connected to each oblique side of one of the pair of horizontal body panels and the front folding panel connected to this rear folding panel are folded, both of them are folded. One quadruple vertex portion formed by overlapping the vertices formed at the tips of each inner rib panel connected to the folding panel, and the rear folding panel connected to each oblique side of the other horizontal body panel. The other 4 similarly formed by folding the front folding panel connected to the rear folding panel.
2. The paper container according to claim 1, wherein the double apex portions are separated from each other in the laminated rib panel so that each of the inner rib panels does not have eight layers. (3) When the rear folding panel connected to each oblique side of one of the pair of horizontal body panels and the front folding panel connected to this rear folding panel are folded, both of them are folded. One quadruple vertex portion formed by overlapping the vertices formed at the tips of each inner rib panel connected to the folding panel, and the rear folding panel connected to each oblique side of the other horizontal body panel. The other 4 similarly formed by folding the front folding panel connected to the rear folding panel.
2. The paper container according to claim 1, wherein the double vertex portions are gathered at one point in the laminated rib panel. (4) When the rear folding panel connected to each oblique side of one of the pair of horizontal body panels and the front folding panel connected to this rear folding panel are folded, both of them are folded. A notch is provided at one quadruple vertex portion formed by overlapping the vertices formed at the tips of each inner rib panel connected to the folding panel, and a notch is provided at each of the oblique sides of the other horizontal body panel. The other quadruple vertex portion, which is similarly formed by folding the installed rear folding panel and the front folding panel connected to the rear folding panel, is in line contact with the cutout portion within the laminated rib. The paper container according to claim 1, characterized in that:
