Abstract: In some examples, a print materials container can include a dispense mechanism to dispense print materials directly to an in-situ reservoir of a printing device, a lock feature to engage a fill port during connection of the dispense mechanism to the fill port, and a valve integrated with the dispense mechanism for connecting the dispense mechanism to the fill port of the reservoir and comprising an output opening offset from a center axis of a tip of the dispense mechanism. The valve can open responsive to rotation of the valve opening with respect to the lock feature such that opposite openings align.
