PROBLEM TO BE SOLVED: To provide an extending container for a solid coating material, which prevents the cave-in or breakage of the slid coating agent and enables the coating material to keep enough strength even under a high temperature. SOLUTION: The extending container 1 has a bearing tray 10 and a rotating shaft 21 screwed onto the bearing tray. The rotation of the shaft 21 makes the bearing tray 10 move in a container body 2, which extendes the solid coating material 3 from the container body 2. The rotating shaft 21 has at least one sloped surface 25 formed by cutting a basic column shape 19, having helical threads on the outer periphery thereof, from its top to bottom. The sloped surface 25 has no threads 24, and the tip end 22 is formed to be wider than the bottom 23. COPYRIGHT: (C)2004,JPO&NCIPI
