ABSTRACT:
A toner container includes a displaceable member located within the container and attached to one end of a flexible membrane utilized to seal the container closed. A bellows member also forms part of the container. Once the container is inserted into the copy machine in a sealed condition, operator initiated pressure upon an outer wall of the container causes the bellows member to collapse and further causes the displaceable member to move downward carrying with it the membrane member. As the membrane member is thus deflected, the seal of the membrane member to the toner container is broken allowing the contents of the container to escape into the copy machine. A safety mechanism is utilized with the container to prevent accidental operation of the displaceable member during shipment or handling.
