Abstract: In one example in accordance with the present disclosure, a refill container is described. The refill container includes a reservoir to house a volume of print compound and a chamber to house a pressurized fluid. A wall separates the reservoir from the chamber. A pressure release device of the refill container creates a fluid path between the chamber and the reservoir such that the pressurized fluid flows into the reservoir to mix with the volume of print compound. A trigger of the refill container activates the pressure release device.

Abstract: In some examples, a print material particles container can include a print material reservoir, a structure adapted to decrease a volume of the print material reservoir to provide an output of print material particles, and a pressure manipulation device adapted to be manipulated while the volume adapting structure is moved from a first position to a third position to aerate the print material particles.
