A system comprising: an imaging device comprising a container slot, a rotating latch, a biasing member; and a consumable supply item to hold an initial or refillable volume of ink for use in the imaging device, wherein the rotating latch is configured to keep in place the supply item during use and wherein the rotating latch is configured to be activated by a user to eject the supply item from the container slot after use by way of the biasing member acting on the supply item, said consumable supply item comprising: a housing defining an interior to retain the volume of ink, the interior oriented during use to deplete the volume of fluid in a direction of gravity toward a bottom surface of the interior, the housing having a top exterior surface that is configured to engage the latch to securely seat the housing in the imaging device to flow the volume of fluid to the imaging device without leaking; and a fluid exit port and an air venting port on a side of the housing that is inserted first into the container slot, wherein a space separates the fluid exit port from the air venting port so that said biasing member can push directly on the side of the housing at the space to eject the supply item from the container slot upon a user activating the latch, the air venting port residing above the fluid exit port as oriented during use and above the volume of ink, wherein a center of the fluid exit port resides no more than 20mm above the bottom surface to minimize stranding the volume of ink in the interior. an imaging device comprising a container slot, a rotating latch, a biasing member; and a consumable supply item to hold an initial or refillable volume of ink for use in the imaging device, wherein the rotating latch is configured to keep in place the supply item during use and wherein the rotating latch is configured to be activated by a user to eject the supply item from the container slot after use by way of the biasing member acting on the supply item, said consumable supply item comprising: a housing defining an interior to retain the volume of ink, the interior oriented during use to deplete the volume of fluid in a direction of gravity toward a bottom surface of the interior, the housing having a top exterior surface that is configured to engage the latch to securely seat the housing in the imaging device to flow the volume of fluid to the imaging device without leaking; and a fluid exit port and an air venting port on a side of the housing that is inserted first into the container slot, wherein a space separates the fluid exit port from the air venting port so that said biasing member can push directly on the side of the housing at the space to eject the supply item from the container slot upon a user activating the latch, the air venting port residing above the fluid exit port as oriented during use and above the volume of ink, wherein a center of the fluid exit port resides no more than 20mm above the bottom surface to minimize stranding the volume of ink in the interior. a housing defining an interior to retain the volume of ink, the interior oriented during use to deplete the volume of fluid in a direction of gravity toward a bottom surface of the interior, the housing having a top exterior surface that is configured to engage the latch to securely seat the housing in the imaging device to flow the volume of fluid to the imaging device without leaking; and a fluid exit port and an air venting port on a side of the housing that is inserted first into the container slot, wherein a space separates the fluid exit port from the air venting port so that said biasing member can push directly on the side of the housing at the space to eject the supply item from the container slot upon a user activating the latch, the air venting port residing above the fluid exit port as oriented during use and above the volume of ink, wherein a center of the fluid exit port resides no more than 20mm above the bottom surface to minimize stranding the volume of ink in the interior.
