  • Patent number: 11230108
    Abstract: There is disclosed a fluid container 200 useable with print apparatus. The fluid container comprises a primary module 210 comprising: a primary reservoir 220 to contain print fluid and a regulated chamber 230 to receive the print fluid from the primary reservoir 220. The regulated chamber 203 comprises a regulator unit 232 to actuate a gas control valve 234 to control a flow of relief gas into the fluid container 200 as print fluid is discharged from the fluid container 200. The fluid container comprises a secondary module 250 comprising a secondary reservoir 252 to contain print fluid. The primary reservoir 220 is to receive the print fluid from the secondary reservoir 252 via a re-supply conduit 260 between the secondary reservoir 252 and the primary reservoir 220. The secondary reservoir 252 is to receive the relief gas via the gas control valve 234, and the primary reservoir 220 is to receive the relief gas via the secondary reservoir 252.

  • Patent number: 10836174
    Abstract: A printing material supply may include a body to contain a printing material, a latch pivotably coupled to the body by a living hinge and a latch protector. The latch protector may include a structure coupled to and projecting from the body so as to contact a packaging surface of a package to inhibit creep of the latch about the living hinge when the printing material supply is contained within the packaging.
