PROBLEM TO BE SOLVED: To provide a device which can sterilize a molded bottle more reliably and efficiently without consuming large thermal energy and a large amount of a medicinal solution.SOLUTION: A plurality of ultraviolet ray emission units are inserted in the inside of a bottle equipped with a mouth part having a circular or approximately circular opening at a tip end, a shoulder part which continues from a rear end of the mouth part and gradually expands, a body part continuing from a rear end of the shoulder part, and a bottom part closing a rear end of the body part. Subsequently, ultraviolet ray irradiation is performed while rotating the bottle after placing the ultraviolet ray emission units in prescribed positions where each unit comes in the proximity of and faces an inner wall surface of a sterilized article that is an irradiation object by moving the ultraviolet ray emission units.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2018,JPO&INPIT【課題】 成形済のボトルを、多大な熱エネルギーや多量の薬液を消費することなく、より確実且つ効率的に殺菌することのできる装置を提供することを目的とする。【解決手段】 先端に円形又は略円形の開口を有する口部と、該口部の後端から連続して次第に拡開する肩部と、該肩部の後端から連続する胴部と、該胴部の後端を閉塞する底部とを備えるボトルの内部に複数の紫外線出射ユニットを挿入した後に、これら紫外線出射ユニットを移動させて、夫々のユニットが照射対象とする被殺菌物品の内壁面に近接して対向するような所定の位置に配置してから、ボトルを回転させながら紫外線線照射を行う。【選択図】図3
