Abstract
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.
Claims20
A key pen for a print liquid supply interface structure, the key pen comprising:
- a base portion;
- and
- a longitudinal key pen portion, the longitudinal key pen portion protruding from the base portion up to at least one actuating surface area that extends at a distance of at least 20 mm from the base portion, along a longitudinal pen axis,
- wherein the base portion comprises a plurality of datums provided at regular positions around a circle having a mid-point on the longitudinal pen axis;
- and
- wherein the plurality of datums facilitate positioning of the key pen in a predetermined rotational position around the longitudinal pen axis with respect to the print liquid supply interface structure.
A key pen for a print liquid supply interface structure, the key pen comprising:
- a base portion comprising a disc and at least one snap finger;
- and
- a key pen portion extending from the disc of the base portion,
- wherein the key pen is configured to be retained within the print liquid interface structure via the at least one snap finger.
A print liquid supply interface structure to fluidically connect a fluid supply container to a receiving station, the print liquid supply interface structure comprising:
- a liquid channel and liquid interface to fluidically connect to a fluid needle of the receiving station, wherein the liquid channel is defined by at least one liquid channel wall, and wherein the liquid channel defines a needle insertion direction;
- a first recess comprising a first base wall on a first side of the liquid channel;
- and
- a second recess comprising a second base wall on a second side of the liquid channel, wherein the first base wall and the second base wall extend next to the liquid channel, approximately perpendicular to the needle insertion direction, at least 10 mm behind a liquid interface edge as measured along the needle insertion direction, and wherein each of the first base wall and the second base wall comprise a hole to receive a key pen.
