DRUG SOLUTION FILLING PLASTIC AMPOULE AND PROCESS FOR PRODUCING THE SAME

摘要

A drug solution filling plastic ampoule that exhibits barrierhood to gases, steam and light and is capable of preventing drug permeation, absorption and adsorption; and a process for producing the same. Drug solution filling plastic ampoule (10) comprises container main body (11), fusion bonded part (13) for sealing mouth part (12) thereof and gripper for wrench off (14) attached thereto. This ampoule (10) has two or more layers, at least one of which is formed from a parison being a functional layer having at least one property selected from the group consisting of gas permeation preventing capability, steam permeation preventing capability, light transmission preventing capability, drug permeation preventing capability and drug absorption/adsorption preventing capability. In particular, the parison extruded from a multilayer blow form die is formed into container main body (11) by means of a lower split mold. Drug solution (15) is charged thereinto, and mouth part (12) is inserted in an upper split mold to thereby form fusion bonded part (13) and gripper (14). Thus, the drug solution filling plastic ampoule can be obtained.
