<p>PURPOSE:To bring expandable floating bodies to a condition, in which their volumes are approximately equal to that of only the material thereof, through discharge of the air between the floating bodies and to reduce the size thereof, by a method wherein the floating bodies are stored in a bag which has air tightness and can be broken through expansion, and the air in the bag is exhausted. CONSTITUTION:A storing bag 4 has an exhaust valve 14, and packings 7 and 8, stores an expandable floating bodies 1 and sealed with a tape 13. By exhausting the air in the bag with the aid of the exhaust valve 14, the bag may be sized to be approximately equal to that of only the material forming the floating bodies, and the floating body may be miniaturized for storage. The bag 4 may be breakable through expansion of the floating bodies 1.</p> |
