Abstract: A print material container comprising a body to hold print material, a housing, and a detecting member. The housing being coupled to the body and including a movable mass to move in the housing when a shaking force is applied to the print material container. The detecting member to detect the shaking force and to signal a feedback of the shaking force relative to a shaking force threshold.

Abstract: An example of a container is disclosed. The example disclosed herein comprises an impermeable container wall, a container releasing valve, and a gas vessel. The impermeable container wall defines the boundaries of an inner volume of the container. The container releasing valve is installed in the container wall to release gas from the inner volume of the container to the outside of the container. The gas vessel is installed in the inner volume of the container. The gas vessel comprises a gas vessel wall, a pressurized vessel gas, and a gas vessel releasing system. The gas vessel wall defines the boundaries of an inner volume of the gas vessel, wherein the gas vessel wall is impermeable and allows for a pressure difference between the inner volume of the gas vessel and an outer volume of the gas vessel. A pressurized vessel gas is enclosed within the inner volume of the gas vessel. And a gas releasing system is to release a certain quantity of the vessel gas to the inner volume of the gas container.

Abstract: Example implementations relate to an apparatus to transfer a quantity of print material to a printing device through a transfer mechanism. In some examples, the apparatus includes a container including the quantity of print material, a transfer mechanism associated with the container, and a sensor associated with the transfer mechanism. In some examples, the sensor is to communicate to the printing device information about the transfer of the quantity of print material through the dispenser mechanism.
