Abstract: An ink bottle is mounted in a DOD printer with the ink bottle acting as an ink supply reservoir that supplies ink to a DOD print head. A unique cap is provided that is configured to be affixed to an end of the ink bottle via threads or the like. The cap can be provided with one or more mechanical keying features used to limit mounting of the cap and the bottle assembly to a correct receiver in the DOD printer. The cap can also be provided with a valve controlled ink passage that allows ink to flow out of the bottle through the cap and a valve controlled vent passage that allows air to enter the bottle through the cap.

Abstract: A system including an ink bottle closure including a first closure member configured to be fixed to an ink bottle, the first closure member including a seal, arranged to be located over an outlet opening in a neck of the bottle and a second closure member attached to the first closure member and movable relative to the first closure member between a closed position, in which the second closure member covers the seal, and an open position in which the seal is exposed to be pierced or ruptured for dispensing ink from the bottle through the outlet opening, wherein the second closure member is movable in translation, relative to the first closure member between the closed position and the open position in a direction substantially perpendicular to a central or longitudinal axis of the bottle and a dispensing device for opening an ink bottle closure, including an adapter having a receiving area for receiving the ink bottle closure of an ink re-fill bottle with the bottle in an inverted orientation, a mechanism for

Abstract: There is provided a tank including: a liquid storage chamber; an outer wall having an inner surface and an outer surface; a cylindrical wall; an inlet port; an outlet port; and a cap for the inlet port. The cap has a seal portion configured to contact an inner circumferential surface of the cylindrical wall or of the outer wall defining the inlet port, or contact an end surface of the cylindrical wall exposed to the outside of the tank, in a state that the cap is installed in the inlet port; and a plurality of stoppers each of which has an abutting surface configured to contact the tank toward the first direction under a condition that the cap is being moved toward the first direction from the state of being installed in the inlet port.

Abstract: A device for filling a writing utensil with a writing liquid has a container having an interior for receiving the writing liquid and a container opening for refilling the interior with the writing liquid. A receiving member is inserted into the container opening so as to provide a tight seal between the receiving member and the container opening. An air inlet connection connects the interior to the atmosphere. A capillary conveying connection, including a first and a second end, is provided for conveying the liquid from the interior to a writing utensil, wherein said first end opens into the receiving member for contacting a writing tip of a writing utensil to be inserted into the receiving member. A seal, connected to the receiving member, seals the writing utensil inserted into the receiving member toward the atmosphere.
