Patent number: 11858273Abstract: In one example in accordance with the present disclosure, a printing fluid container for a printing system is described. The printing fluid container includes a container body for holding printing fluid, a collar connected to the container body, and a cap removably engaging the collar. The collar has a plurality of collar teeth extending peripherally around the collar. The cap has a plurality of cap teeth extending peripherally around the cap. The cap teeth are configured for interfitment with the collar teeth such that rotation of the cap about the longitudinal axis in a first rotational direction effects cam-actuated removal of the cap from the collar.Type: GrantFiled: April 17, 2020Date of Patent: January 2, 2024Assignee: Hewlett-Packard Development Company, L.P.Inventors: Zachary T. McCourt, Patrick V. Boyd, David M. Hagen, James A. Dewey

Patent number: 6981763Abstract: A fluid containment structure includes a containment vessel having an interior vessel space for fluid containment, and a fluid outlet communicating with the interior vessel space. A flexible bag with opposed side surfaces is disposed within the containment vessel, vented to an external atmosphere outside the containment vessel. A sacrificial bond structure is formed between the side surfaces, and restrains the side surfaces together until a back-pressure within the vessel space exerts sufficient force to break the sacrificial bond structure, allowing air from the external atmosphere to enter the bag and enlarge an interior bag space.Type: GrantFiled: December 10, 2003Date of Patent: January 3, 2006Assignee: Hewlett-Packard Development Company, L.P.Inventors: Anthony D. Studer, Kevin D. Almen, David M. Hagen, David J. Benson, Cary R. Bybee
