Abstract
A spear head access mechanism in a liquid development system wherein a machine mounted manifold, bearing a flow-through spear head connects the developer delivery system to a storage bottle. The bottle has a self sealing closure through which the spear head is forced and is encircled in an air tight manner when the bottle is pushed into operational position. A suction tube within the bottle is entered by the spear head. Upon removal of the bottle from the machine the self sealing closure forms a liquid tight seal preventing spillage of any remaining contents.
