<P>PROBLEM TO BE SOLVED: To prevent leakage of a filling material, and to improve quality and usability by eliminating a case where the filling material does not readily appear. <P>SOLUTION: This container for extruding filling material is so constituted that, when a container front part 2 and a container rear part 3 are relatively rotated in one direction, a moving body 6 advances to extrude the filling material L in a filling area 1x in a container 100 and makes L appear from an opening part 1c at the tip of the extrusion container into a use state. Also, when the container front part 2 and the container rear part 3 are relatively rotated inversely to one direction after the use, the moving body 6 in an optional advancement position is retracted. After the use, a space B is formed inside by the opening part 1c at the tip of the container, so that even if the filling material L and air mixed with the filling material L is expanded by a temperature change and a change in the barometric pressure, the space B prevents the filling material L from being leaked from the opening part 1c. The moving body 6 is retracted a prescribed distance and stops. That is to say, this filling material extrusion container is constituted not to retract more than the prescribed distance, to prevent the excessive retraction of the moving body 6 and to prevent the filling material L from not readily appearing from the opening part 1c at the next use. <P>COPYRIGHT: (C)2007,JPO&INPIT |
