Ink cartridge

A print liquid supply apparatus comprising a container to hold print liquid and an interface structure to fluidically connect the container to a receiving station wherein the interface structure projects outwards with respect to the container and comprises a liquid interface to fluidically connect to a corresponding fluidic interface of the receiving station and a liquid channel fluidically connecting the container and the liquid interface.

Print liquid supply

Key for a print liquid supply cap

A print liquid supply apparatus or interface structure to be connected to a print system comprises a liquid channel, liquid interface and integrated circuit contact pads.

An interface structure connectable to a separate liquid reservoir, to connect that liquid reservoir to a receiving station, comprising a liquid interface to fluidically connect to at least one liquid needle of the receiving station, a liquid channel, to fluidically connect the liquid interface to the reservoir, a support wall supporting an integrated circuit laterally next to the liquid channel, the integrated circuit having contact pad contact surfaces, and a front push area adjacent the liquid, the front push area terminating at a front edge that defines a profile height of the interface structure, between said front edge and an opposite distal edge.

A print liquid supply interface structure is provided, to fluidically connect a fluid supply container to a receiving station, comprising a liquid channel having at least one liquid channel wall, the liquid channel including a liquid interface, and at least one key pen next and parallel to the needle receiving portion of the liquid channel. In another example a key pen structure is provided. In yet another example an interface structure for receiving a separate key pen is provided.

In one embodiment a sub-assembly of components is provided to assemble a print liquid supply container, the set including a reservoir and a support structure to form a print liquid supply container, the container having a first, second and third dimensions, the support structure to at least partially surround and support the reservoir and to provide stiffness to the container, at least in a folded and mounted condition, the reservoir including a bag to hold the print liquid, being at least partially flexible to collapse for print liquid to be withdrawn from the reservoir, the bag being configured to inhibit fluid exchange, and a neck that is relatively narrow with respect to the bag in a filled state, with an opening to output print liquid from the bag.

Combined print liquid supply cap and key

In one embodiment a print liquid supply apparatus is provided to supply liquid to a liquid needle of a receiving station comprising a liquid container including an at least partially collapsible liquid reservoir an interface structure at a side of the container, including a liquid channel that includes a reservoir connecting portion that fluidically connects to the reservoir and a needle receiving portion to allow the liquid to flow from the reservoir to the needle; a liquid interface of the liquid channel adjacent the needle receiving portion and at a distance from the reservoir connecting portion, a front wall and/or edge adjacent the liquid interface including a push area which is disposed between the liquid interface and the container; and at least one key pen base and key pen protruding from the base in a direction parallel and opposite to the needle insertion direction; and a contact pad array next to the needle receiving liquid channel portion. In another example a sub-assembly of such apparatus is provided.

A print liquid supply interface structure is provided, to fluidically connect a fluid supply container to a receiving station, comprising a liquid channel having at least one liquid channel wall, the liquid channel including a liquid interface, and at least one key pen next and parallel to the needle receiving portion of the liquid channel, protruding from a base over more than 10 millimeters. In another example a key pen structure is provided. In yet another example an interface structure for receiving a separate key pen is provided.

A liquid supply, may include a bag and a box to maintain the bag therein, the box including a number of alignment structures formed along an edge of a first wall of the box to mate with a support element. A carton fold structure for a print liquid supply, the fold structure to support and hold a liquid bag including a liquid bag interface, the carton fold structure including multiple planes that, together, form a cuboid shape, each plane to form an outer wall of the carton fold structure, with edges between respective planes; a cut out in one of the edges, the cut out including: a channel extending inwards into a first plane to allow the liquid bag interface to pass through the first plane; and slots extending into the first plane between the channel and the edge associated with the first plane to align to a support element.
