Abstract

A sterilization apparatus comprises a housing provided with an opening through which an object may be inserted, and an ultraviolet radiation generator at least partially inside the housing for irradiating with bacteriocidal radiation an object inserted into the housing through the opening. A liquid spraying mechanism or gas injection mechanism is disposed at least partially inside the housing for applying to the inserted object a sterilizing agent. A coating or cover forming mechanism is also provided at least partially inside the housing for forming on the inserted object a protective covering. A control unit controls the activation of the radiation generator, the sterilizing mechanism and the coating mechanism.
