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.

Abstract: One example provides an article. The article includes a container body. The article includes a lid covering the container body, the lid including a lid aperture to permit passage of a printing fluid into the container body. The article includes a lid manifold mounted to the lid. The lid manifold includes a lid manifold input port to be fluidly connected to and disconnected from a container manifold port of a separate printing system. The lid manifold includes a lid manifold output opening that is in the form of a needle having a length of less than or equal to about 6 mm and is fluidly connected to the lid aperture. The lid manifold includes a channel fluidly connecting the lid manifold input port and the lid manifold output opening.
