FLUID CONTAINER HAVING MIXING CHAMBERS FOR MICRO-FLUID APPLICATIONS

摘要

A consumable supply item for an imaging device holds an initial or refillable volume of pigmented ink. Its housing defines an interior and exterior. The interior retains the ink and an exit port supplies it to an imaging device. Users orient the housing to deplete the ink in a direction of gravity toward a bottom surface of the interior en route to the exit port. The ink passes through a mixing chamber having inlet ports arranged to restrict to multiple different heights the entrance of the volume of ink from the interior. As ink draws from various heights into the chamber, sediments in the pigment mix together. The design overcomes settling. It also avoids mechanical stirring and other complex mixing techniques. Further embodiments include chamber shapes, configuration of inlet ports, and construction of the supply item, to name a few.
