Abstract
This invention relates to a replaceable ink container or bottle (1) for an ink jet printing apparatus in which the mouth of the bottled is closed by a puncturable diaphragm (19). A puncturing member (35) carried by the ink reservoir (21) of the ink jet printing apparatus pierces through the diaphragm upon the container being installed in the ink jet printing apparatus. Upon the puncturing member (35) puncturing through the diaphragm (19), the diaphragm sealingly engages the sides of the puncturing tube so as to substantially prevent the ink from leaking therepast, and the puncturing tube opens communication between the ink within the container and the ink reservoir thereby permitting ink to flow from the bottle into the ink reservoir via the puncturing member. An air path (37) is provided which is in communication with the atmosphere and with the reservoir so that ink from within the container and atmospheric air may be exchanged via the puncturing member so that ink is free to flow from the container into the reservoir, and so that the pressure within the container is maintained substantially at atmospheric pressure. A method of supplying ink to such an ink jet printing apparatus …
