ABSTRACT:
A toner hopper seal-insert and slide-seal to provide for the shipping and transporting of a re-filled toner cartridge used in printers and copying machines. The seal-insert is comprised of three slotted rectangular strips or pieces of material. A middle piece is sandwiched between two outer pieces. The slot in the middle piece is wider and open at one end, providing a channel for the slide-seal. The seal-insert is attached to the toner hopper of the toner cartridge, and the slide-seal is slid into or out of position in the seal-insert to seal or unseal the opening of the toner hopper, creating a reusable leakproof seal system. When the constriction in the end of the toner hopper is narrower than the width of the area being sealed, the slide-seal may be made narrow enough and the dimensions of the seal-insert slots may be made such that the slide-seal can be slid through the contriction and still seal the toner hopper opening to prevent the passage of toner.
