<P>PROBLEM TO BE SOLVED: To provide a self-standing carton which is simple to manufacture, easy to assemble without complexity, and can support itself stably. <P>SOLUTION: The carton (20) is equipped with an unsealing port (4) on one of surfaces (1) of a rectangular hexahedron and has a pasting margin (3) formed on the opposite surface (2) via a crease (s). One surface with the unsealing port and two adjacent surfaces are divided into two parts of a lid (5) and a body (6) via a breaking line (t) formed from a start-to-tear point (r). In addition, the lid (5) and the body (6) are folded to bend in an acute angle via the crease (s) connecting with the breaking line (t) on the surface with the pasting margin (3) formed. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
