IPC: B65D88/10
Filed: 1987-12-25
Abstract: PURPOSE:To maintain sterilizing capability for a long time at a high level by a method wherein a sterilizing device with a sterile filter and a device for heating the filter are provided in an air path. CONSTITUTION:A tube 2 constituting an inlet/exhaust port X has inside it an ultraviolet ray lamp 5 for example and a membrane filter 3 which composes a sterilizing device A.
