ABSTRACT:
A sanitizing device for a telephone. A housing is mounted alongside the telephone and includes two pair of openings, each pair spaced to receive the mouthpiece and earpiece of the telephone. Located within each opening of the first pair is a nested stack of sanitized cup-like filters and the inner surface of the periphery of each filter bears a strip of pressure sensitized adhesive. By inserting the mouthpiece and earpiece within the respective openings, a filter will adhere to both the mouthpiece and earpiece. To remove the filters after use of the telephone, the mouthpiece and earpiece are inserted within the openings of the second pair and spiral rubber-like flaps which are disposed across each opening act to remove the filters as the receiver is withdrawn. In a second form of the invention, the sanitizing device takes the form of a rigid adapter including a perforated mouth section and a perforated ear section which is snap fitted over the receiver of the telephone. After use, the adapter is stored in a box containing a sanitizing agent.
