<p>PURPOSE: To provide a container of the type which has four paired horizontal side walls connected with bottom panels to be folded one another by folding lines and is provided with high watertightness and resistance to leakage. CONSTITUTION: A bottom section is designed into the constitution in which the pointed ends of triangular refold panels are formed inside a package, and at the time of handling, the mechanical damage to an internal watertight plastic layer can be generated by the pointed ends. For the purpose of avoiding the damage, incision lines are formed on both sides of the pointed ends, and tongues 13 are formed between the incision lines, and the plane state of the tongues 13 is maintained when the bottom panels 6 are folded and the blank for bottom sealing the container package is provided to avoid the formation of pointed ends and guarantee the watertightness.</p> |
