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.
