Abstract: A xerographic copying machine is adapted to receive toner supplied from an inverted toner supply bottle having a frangible seal member covering its outlet. The toner bottle is inserted by an operator through an access receptacle within the copier which normally covers a toner developing apparatus and toner supply container. During insertion, mutually engaging components of the toner bottle and a cooperating connecting apparatus are aligned to enable operative association of the components when the toner bottle is manually turned. In addition, during insertion the frangible seal member normally sealing the toner bottle dispensing opening is punctured by a piercing member associated with an actuating device including a cutting device rotatably mounted on the connecting apparatus. When the bottle is turned, the piercing member is caused to rotate within the neck opening of the bottle, thereby helping the toner to be dumped through the toner loading apparatus and into the toner supply container.
