Fluid interconnect for ink-jet pen

摘要

A fluid interconnect connects an ink pen to a carriage on an ink-jet printer. The ink pen has an inlet assembly having a septum. The carriage has an outlet assembly that includes a collar and a needle with a lateral hole. The inlet assembly is insertable into the outlet assembly to move the collar from a closed position, in which the collar covers the lateral hole, into an open position, in which the lateral hole is exposed within the inlet assembly, to allow ink to flow through the outlet assembly into the inlet assembly. The septum occludes fluid flow from the inlet assembly when the inlet and outlet assemblies are uncoupled. The septum has a blister that seals the inlet assembly against the outlet assembly when the inlet and outlet assemblies are coupled. The inlet assembly also has a ridge for attracting, by capillary attraction, any fluid that may escape from the interconnect.
