PROBLEM TO BE SOLVED: To provide a liquid material filling and packing structure that prevents a self-standing outer packing container having a dispensing function from bending along a ripping guide flaw and a film-type one-way nozzle located insid the outer packing container from being deformed, and excels in liquid drip-controllability and the self-standing characteristic of the outer packing container. SOLUTION: The liquid material filing and packing structure includes a liquid material filling inner packing body of a non-self-standing type convexly arranged with a film-type one-way nozzle and filled with a to-be-packed product in a flexible package bag formed by giving a concavo-convex structure in at least one of a surface laminate film or a back laminate film of a package bag body. The liquid material filing and packing structure further includes a self-standing outer packing container as a cylindrical shaped container for accommodating the inner packing body in which a protruded small bag having the ripping guide flaw for exposing the nozzle is convexly arranged at a position corresponding to the film-type one-way nozzle and a bottom that enables the self-standing is provided. The ripping guide flaw formed between the upper and lower ends of the small bag is formed into a concave wave shape in the center. COPYRIGHT: (C)2011,JPO&INPIT |
