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.

Abstract: A housing has two openings to receive the electrically conductive prongs of a plug to mount the housing and a third opening to receive the grounding prong. Electrically conductive strips are disposed within the housing and have the conductive prongs of the plugs, which pass through the two openings in the housing, pass through openings in the electrically conductive strips to be in contact with the strips to provide a source of power to the strips, which are electrically connected to an alarm circuit. The alarm circuit produces an audible signal whenever there is no current through the plug due to a power failure or the plug being removed from its power source and a battery, which is supported within the housing, is connected to this alarm circuit.
