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.
Claims12
A liquid development delivery system in a printing machine, including a removable container of liquid developer material, a development fountain, delivery fluid conduit for transporting developer between said container and said fountain, and suction means for withdrawing developer from said supply container and delivering it in said system, said system being characterized by
- a developer access manifold, secured in said printing machine, comprising flow-through piercing means
- connection means in said container comprising sealing means through which said piercing means is penetrated and is encircled thereby in a substantially air-tight manner when said container is operatively coupled to said printing machine and wherein said sealing means forms a substantially fluid-tight closure upon removal of said piercing means when said container is uncoupled from said printing machine, and
- means, located within said container, through which liquid developer is withdrawn, said withdrawal means being in communication with said connection means and positioned such that said piercing means enters said withdrawal means when said container is coupled to said printing machine.
