  • Patent number: 10219532
    Abstract: A sterilization tray is composed of a tray body and a pressing member capable of moving in a direction perpendicular to the tray body. The bottom of the tray body is formed from a perforated plate through which high pressure steam or hot water passes at the time of moist heat sterilization, and a frame of the pressing member is formed from a porous member through which steam or hot water passes. When plural sterilization trays are stacked in a state in which a resin container (multi-chamber container) 1 is placed on the sterilization tray, the peripheral edge of an empty chamber part of the resin container is pressed by the pressing member of the sterilization tray stacked above, and deformation of the resin container during the moist heat sterilization can be prevented.
