Abstract: In one example in accordance with the present disclosure, a clamp plate assembly for a print liquid supply is described. The clamp plate assembly includes a clamp plate which includes 1) two wedge-shaped forked ends to facilitate clamping a spout to a container in which a print liquid reservoir is disposed and 2) a slot defined by the forked ends to receive and retain the spout. The clamp plate assembly also includes a back plate approximately orthogonal to the clamp plate.

Abstract: 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.

Abstract: 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.
