ABSTRACT:
The sealing device is of the type that can be passed across an envelope to moisten the flap and then passed back to press the moistened flap against the envelope. The moistening pad is held between a lower base member and a cover so that only a small area of the pad is exposed to the elements. The lower base member is constructed so as to readily admit a starting portion of the flap into the area between the cover and the pad and means are provided on the pad to press the flap against the pad as the device is moved across the envelope. Water or moistening liquid is supplied to the pad from a chamber which serves as a holding means for the pad and the chamber is so constructed that water does not flow to the pad except when the device is in motion.
