Abstract
A germicidal mailbox receives mail in an internal, rotatable cage, and tumbles such mail while irradiating it with ultraviolet light at a wavelength of 254 nanometers to kill or render inert microbes on the mail that could carry diseases to which humans are susceptible. After the mail has been tumbled and irradiated, it is safe for handling by humans without the danger of infection and disease from microbes that may purposefully, through terrorism, or accidentally have become attached to the mail.
Claims12
A germicidal mailbox comprising:
- an outer housing, said outer housing being opaque to ultraviolet light and having one or more access doors;
- said outer housing enclosing an interior cage, said cage being at least large enough to receive articles of mail of standard sizes, said cage being rotatable along a longitudinal axis;
- an electric motor electrically connected to a first circuit and being in series with a first switch, and having a physical interconnection to said cage for rotating said cage when said motor and said first circuit are activated by closing said first switch;
- an ultraviolet lamp located within said housing and outside of said cage, said lamp being electrically connected to a second circuit being in series with a second switch, said lamp being physically situated to irradiate the interior of said cage when said second circuit is actuated by closing said second switch;
- said first switch becoming closed upon the occurrence of a first predetermined event, and said second switch becoming closed upon the occurrence of a second predetermined event;
- said lamp, when activated for a predetermined length of time, radiating ultraviolet light at a wavelength sufficient to render microbes located on articles of mail situated within said cage incapable of transmitting disease to humans;
- a power source connected to said first and second circuits such that, when said first and second switches are closed, said cage will rotate and articles of mail contained within said cage will tumble, and said lamp will radiate ultraviolet light sufficient to render microbes within said cage harmless.

A germicidal mailbox comprising:
- an outer container having one or more access doors, said outer container substantially enclosing an ultraviolet lamp such that ultraviolet radiation produced by said lamp is confined within said outer container when said one or more access doors are closed;
- a rotatable mesh container that is large enough to receive and tumble articles of standard size mail when rotated;
- an electric motor having a shaft mechanically interconnected to said mesh container;
- an electrical circuit having a power source, said ultraviolet lamp and said electric motor being connected to said circuit and being actuated by at least a first switch and one or more second switches;
- said one or more second switches being proximate to and corresponding to said one or more access door and configured to allow said electric motor and said ultraviolet lamp to operate only when said one or more access doors are closed;
- such that articles of mail contained within said mesh container will be tumbled and irradiated with ultraviolet radiation when said access door is closed and said first switch is closed.
