ABSTRACT:
A seal for sealing a toner filling aperture of a housing of a refilled toner cartridge is provided. The cartridge includes a ruptured closure positioned on the housing adjacent the aperture. The housing and the closure cooperate to define a non-planar surface adjacent the periphery of the aperture. The seal includes a body having a first surface thereof conforming to the periphery of the aperture. The body has an opening therein. The seal also includes a member secured to a second surface of the body. The second surface is opposed to the first surface. The seal also includes an adhesive secured to the first surface of the body. The adhesive conforms to the non-planar surface and seals the body to the closure and the housing so as to permit the cartridge to be sealed without removal of the closure.
