PROBLEM TO BE SOLVED: To provide a medical container which reliably administers medicaments without adhesion, adsorption, or permeation of the medicaments to or in the medical container during the manufacture, storage, transportation, or use if the medicaments which are easily taken into a container made of a thermoplastic resin are housed.SOLUTION: The container which is made of the thermoplastic resin and has a plurality of chambers contains pharmacologically effective substances. A manufacturing method of the medical container and the manufactured medical container are characterized by coating the inside after retaining a shape expanded by introducing a gaseous body while a temperature of a glass-transition temperature or higher is applied to the inside of at least one chamber brought into contact with the substance and by cooling it.COPYRIGHT: (C)2009,JPO&INPIT【課題】熱可塑性樹脂製容器に取り込まれやすい薬剤を収納しても、製造、保存、輸送、使用中に薬剤を医療容器へ付着・吸着・浸透させることのなく、確実に薬剤を投与することができる医療用容器を提供する【解決手段】薬理学的に有効な物質を含有する熱可塑性樹脂製複室容器であって、前記物質と接触する少なくとも一室の内部をガラス転移点以上の温度を加えながら、気体を導入、冷却することによって膨張させた形を維持させた後、内部をコーティングすることを特徴とする医療用容器の製造方法および製造された医療用容器。【選択図】図1
