Abstract: A container for holding a volume of fluid includes a housing defining an interior for retaining the volume of fluid, a vent system disposed at an upper portion of the interior adjacent to a fluid chamber to vent air to atmosphere. The vent system includes an air chamber in fluid communication with the fluid chamber through an air inlet and disposed within the interior. The air chamber includes a bottom surface angling from the air inlet towards a distal end of the air chamber.

Abstract: A consumable supply item for an imaging device holds an initial or refillable volume of fluid. An interior holds the fluid and users orient a housing to deplete the fluid in a direction of gravity. An air conduit tube fluidly connects to an air port to vent the interior to atmosphere. A float buoyantly supports the tube on a surface of the volume of fluid. It suspends a terminal opening of the tube above the fluid so that as the volume of fluid depletes in the interior over time, or an orientation of the housing is altered during handling, the terminal opening is maintained above the surface of the volume of fluid. Fluid leakage is minimized during transport and manipulation.
