PROBLEM TO BE SOLVED: To provide a thermoplastic elastomer composition for a cover for mouth part stopper body of a liquid medicine container which prevents the cover for mouth part stopper body of the liquid medicine container from being pseudo-soldered to the stopper body in the process of heating sterilization, and to provide the cover for mouth part stopper body of the liquid medicine container.
SOLUTION: In the thermoplastic elastomer composition, as materials for the cover 4 for a mouth part stopper body 3 of the liquid medicine container, 1 to 100 parts by mass of polypropylene, 50 to 200 pts.mass of high-density polyethylene, 0.5 to 20 pts.mass of silicone resin are added to mixture 100 parts by mass of one or more kinds of 20 to 80 pts.mass of styrene thermoplastic elastomer selected from among groups comprising a styrene-ethylene-butylene-styrene block copolymer, a styrene-ethylene-propylene-styrene block copolymer, and a styrene-ethylene-ethylene-propylene-styrene block copolymer, and 80 to 20 pts.mass of softening agent.
