  • Patent number: 10485889
    Abstract: A sterilization case can be reduced, and it is possible to reliably sterilize not only the surface of a mobile communication device but hidden portions thereof as well. A sterilization case includes a case main body and a cover body. The case main body includes a voltage supplying part and a loading part having an electrode sheet. The voltage supplying part includes a boosting circuit, a direct-current conversion circuit, a switch circuit, and a sterilization meter. The boosting circuit supplies the voltage necessary to generate ozone to the electrode sheet. The direct-current conversion circuit performs conversion to a power source voltage of a smartphone as the mobile communication device and outputs to a male connector. The male connector can be connected to a female connector of the smartphone. The cover body is attached to the case main body so as to be able to open and close.

  • Patent number: 10376606
    Abstract: A sterilizing sheet is excellent in terms of saving space when a sterilizing operation is being performed, and sterilizing objects of various sizes. This sterilizing sheet is provided with a flexible sheet body, a sheet accommodating body and a handle. The sheet body is formed from a dielectric and a pair of electrodes accommodated inside the dielectric. The sheet accommodating body is a cylindrical body in which the sheet body is accommodated to be capable of being pulled out and rewound, and is provided with a case, a rotating body and a rewinding mechanism. The rewinding mechanism is a mechanism for automatically rewinding the sheet body, when pulled out from the sheet accommodating body, back into the sheet accommodating body. The handle is attached to a distal end portion of the sheet body, and includes, inside the handle, a battery, a switch mechanism, a booster circuit and a monitoring circuit.
