<p><P>PROBLEM TO BE SOLVED: To fill a sealing material without forming a cavity. <P>SOLUTION: A casing (11) used for a refrigerating container has a through-hole (H) through which a pipe for a refrigerant circuit is inserted. Both openings of the through-hole (H) are covered with meshed sheets (31, 32). In this state, the tip of a filling nozzle (33) is inserted into the center of the through-hole (H), and the sealing material is filled therein. Thus, the filled sealing material is held by the meshed sheets (31, 32), while air in the through-hole (H) is purged through the meshed sheets (31, 32) by the filling of the sealing material. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
