Abstract: Examples described herein relate to a system for a print cartridge. For instance, the system may comprise a coupling member to connect to a printing device, a roller mechanism coupled to the coupling member, where a position of the coupling member relative to the roller mechanism remains the same as the coupling member and roller mechanism transition between a first position and a second position, and an urging member positioned away from the coupling member, where the urging member is to transition the roller mechanism from the second position to the first position.

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: A seal removal structure can include a shell and a piercing member. The shell can have a first end section and a second end section. The first end section can be configured to receive a supply conduit of a supply fluid container and the second end section can be dimensioned to receive a receiving conduit of a container device. Additionally, the piercing member can be provided within the first end section to penetrate a seal of the supply conduit when the supply conduit is received by the first end section. Moreover, the piercing member can incise at least a portion of the seal from the supply conduit when the supply conduit or the piercing member rotates, while the supply conduit is received by the first end section.

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.
