Abstract
A consumable supply item for an imaging device holds an initial or refillable volume of ink. Users orient a housing to deplete the ink in a direction of gravity toward a bottom of the interior. The imaging device has a rotating latch. The latch mates with a top of the supply item to keep in place the supply item. Fluid exit and air venting ports reside on a side of the housing that gets inserted first into a container slot of the imaging device. A space separates the ports so a biasing member can push against the housing to assist in ejecting the supply item upon users activating the latch. The ports are separated a maximum distance to facilitate the ejection, while the exit port remains near a bottom to minimize stranding ink. Further embodiments note arrangements, distances and consumer features, to name a few.
