<p><P>PROBLEM TO BE SOLVED: To provide a paper container having an increased strength by making a barrel constituting surface in such a shape that triangles are adjacent while alternately inverted to prevent a barrel from swelling and contents from coming out even if an external pressure is accidentally applied, and further which is formed in a shape easy to hold when in use, can express three-dimensional design compared with a conventionally standardized and flat rectangular parallelopiped barrel form to be excellent in solid design in displaying an article, and is excellent in productivity. <P>SOLUTION: The paper container consists of: square bottom constituting plates; four upward isosceles triangular barrel constituting plates standing from respective sides of the bottom constituting plate; four downward isosceles triangular barrel constituting plates, each consisting of two hypotenuses provided between the adjacent upward isosceles triangular barrel constituting plates and an upper side connecting between vertexes of the adjacent upward isosceles triangular constituting plates and having the same size as that of one side of the bottom constituting plate; and square top constituting plates having various upper sides of the respective downward isosceles triangular barrel constituting plates as ridges. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
