PURPOSE:To make the transport and the housing easier by sealing a single-liquid type water hardening foamy resin undiluted solution in a bag body formed of a water-soluble material, housing the bag body in a container body formed of a water-permeable material, and expanding it when it is used. CONSTITUTION:A bag body 1 is formed of a material soluble by the water, and a foamy resin undiluted solution 2 is sealed therein. And a container body 3 is formed of a material of a high flexibility and a water permeable property, and the bag body 1 including the solution 2 is housed in the container body 3. Then, by dropping the container body 3 in the water, the water infiltrates into the container body, the reaction of the solution 2 is started, the volume of the container body 3 is expanded 10 to 15 times the volume when the solution is housed, and it is floated on the water. As a result, the transport, the housing, and the like before it is used can be made easier. |
