Abstract: Example implementations relate to print substance container vibration. A vibrator for a print system may comprise a motor, and a vibration shaft coupled to the motor to cause vibration to provide redistribution of print substance of a print substance container. The vibration may be caused in response to the rotation of an eccentrically loaded weight about a central axis of the vibrator.

Abstract: An example of a device (100) may include a valve body (108). The device (100) may include a printing substance transfer aperture (122) through the valve body (108). The device (100) may include a hood (138), fixed to the valve body (108), encompassing the printing substance transfer aperture (122) within a cavity between an external face (137) of the valve body (108) and the hood (138). The device (100) may include a printing substance dispensing nozzle (110) movable between a first position with an orifice (126) of the printing substance dispensing nozzle (110) facing an internal face of the valve body (108) and a second position with the orifice (126) of the printing substance dispensing nozzle (110) facing the printing substance transfer aperture (122). The device (100) may include a dispensing-side gasket material (132) slide-able through the printing substance transfer aperture (122) when moving the printing substance dispensing nozzle (110) between the first position and the second position.

Abstract: In an example, a print component includes a guide structure. The example guide structure includes a recess to receive a print material container and a guideway with a guide wall to support rotation of the print material container. Upon rotation of the print material container, an electrical contact of the print material container moves towards an electrical contact coupled to the guide structure of the print component. In another example, a container includes a housing, a material transfer interface, and a mechanical interface. In that example, the mechanical interface includes a guide structure that defines a protrusion and a guideway to allow the container to rotate within a recess defined by a receptacle shell. Upon rotation of the container, an electrical contact coupled to the guide structure moves towards an electrical contact on the receptacle shell.

Abstract: An example of a device (100) may include a valve body (108). The device may include a printing substance transfer window (122) through the valve body (108). The device (100) may include a printing substance dispensing nozzle (110) rotatable within the valve body (108) between a first orientation with an orifice of the printing substance dispensing nozzle (110) facing an internal face of the valve body (108) and a second orientation with the orifice (126) of the printing substance dispensing nozzle (110) facing the printing substance transfer window (122). The device (100) may include a dispensing-side gasket material (132) slideable against the internal face of the valve body (108) when rotating the printing substance dispensing nozzle (110) between the first orientation and the second orientation.

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: A device may include a dispensable substance container to hold a dispensable substance; a dispensing nozzle attached to the dispensable substance container to dispense the dispensable substance out of an opening in the dispensing nozzle; and a frangible obstruction encompassing the dispensing nozzle and obstructing the opening of the dispensing nozzle wherein the frangible obstruction is to slide along the dispensing nozzle to uncover the opening when broken free from the dispensing nozzle by a wall of a receiving container during an engagement between the dispensable substance container and the receiving container.
