  • Collapsible container and sensor
    Patent number: 10800176
    Abstract: An example printhead assembly includes a housing, nozzles and a collapsible container within the housing to supply ink to the nozzles. The collapsible container includes a top wall, a bottom wall, first and second side walls that form an interior and a spring assembly within the interior. The first flexible wall includes a first amount of excess material. The second flexible wall includes a second amount of excess material less than the first amount of excess material such that motion of the first flexible wall of the collapsible container is constrained against movement to a lesser extent as compared to the second flexible wall. The first flexible wall faces the sensor. A sensor assembly is coupled to the housing and includes a sensor to provide a sensor signal indicating the amount of ink within the collapsible container.
