<P>PROBLEM TO BE SOLVED: To allow foaming molding processing of polylactic acid resin foaming particles, which can produce a foamed molded product when they are heated with water at 60-100°C and have crystallinity of ≤30% and an open cell ratio of ≤30%, in an optional place at optional time. Ž<P>SOLUTION: The polylactic acid resin foaming particles 10 with crystallinity of ≤30% and an open cell ratio of ≤30% are enclosed in the airtight container 20. The airtight container 20 enclosing the polylactic acid resin foaming particles 10 is combined with a molding mold 30 to constitute a combination body 40 for application to physical distribution and storage. The combination body 40 can be effectively used as a learning material, a toy and a supplement of a magazine. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
