PROBLEM TO BE SOLVED: To provide a sterilizing apparatus that can uniformly irradiate a container to be sterilized with ultraviolet rays emitted from a light source without the loss of the ultraviolet rays.SOLUTION: The apparatus for sterilizing a container of the present invention includes: one or plural light sources 4 that emits ultraviolet rays when electric power is supplied to the light sources 4 a light source support 6 that supports the light sources 4 and can relatively move back and forth, thereby advancing and retreating, in a preform 30 and a cooling mechanism 5 that cools the interior of the light source support 6. The light sources 4 are preferably light sources in which a housing 41 with a bottom, an LED light-emitting element 43 that is disposed in a housing void 42 of the housing 41, a sealing material 45 with which the housing void 42 is covered from a front face side, and electrodes 47, 47 that are disposed on a back face of the housing 41 and become feeding points from an outside are packaged.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2017,JPO&INPIT【課題】光源から出射される紫外線をロスなく、かつ殺菌対象である容器に均等に照射できる殺菌装置を提供する。【解決手段】本発明の容器の殺菌装置は、電力の供給を受けて紫外線を発光する単数又は複数の光源4と、光源4を支持し、プリフォーム30の内部を相対的に往復移動して進退が可能な光源支持体6と、光源支持体6の内部を冷却する冷却機構5と、を備えることを特徴とする。 光源4としては、有底のハウジング41と、ハウジング41の収容空隙42に設けられるLED発光素子43と、収容空隙42をおもて面側から覆う封止材45と、ハウジング41の背面に設けられ外部からの給電点となる電極47,47と、を備えるパッケージ化されたものが好ましい。【選択図】図2
