Fluid container having latching interface for micro-fluid applications

Abstract A consumable supply item for an imaging device holds an initial or refillable volume of fluid. Users orient a housing to deplete the fluid in a direction of gravity toward a bottom surface of the interior en route to an exit port. The 5 imaging device has a rotating latch to keep in place the supply item during use. Users activate the latch to eject the supply item. The latch mates with a notch on the supply item. A first face of the notch angles to allow the latch to swing into and away from contact with the notch while a second face substantially parallels a side of the latch when the latch is engaged with the first face. The faces have 10 differing angles and differing lengths. Further embodiments note angular degrees, biasing members, container slots, and consumer features of the supply item, to name a few.
