METHOD OF INJECTING COMPOUND LATEX MATERIAL

摘要

PROBLEM TO BE SOLVED: To improve the yield of a puff for makeup by reducing void and variation of foaming of a column-shaped foam rubber base material. SOLUTION: When a blended latex material 1 is injected via a discharge pipe 3 to a bottomed cylindrical mold 2, the injection is started from a position where the lower end 31 of the discharge pipe 3 is closed to the mold bottom face 21. After that, in association with rise of the level of the blended latex material 1 filled in the mold, the blended latex material 1 is injected while lifting the lower end 31 of the discharge pipe 3 so that the lower end 31 is not come into contact with the level of the material.
