Embodiment Construction
[0027] Referring now to the drawings, there is shown an ink supply system for an inkjet printer in which an ink bottle or container 1 supplies ink to an inkjet head of an inkjet printing device, such as that disclosed in U.S. Patent Application No. 08 / 728,774 public. For the purpose of brevity, only the ink bottle 1 and the structures in the inkjet printing device that need to be related to the bottle 1 and receive ink from the bottle 1 are described here.
[0028] As shown in FIG. 2, the ink bottle 1 is in an upside-down position when installed in the inkjet printing apparatus. The bottle 1 has a body 3 with a closed bottom 5 , a neck 7 and a mouth 9 . The neck 7 of the bottle 1 has a suitable external thread 11 ( Figure 5 ), and has an internal thread 16 (see Figure 5 ) of an appropriate cap 15 is threaded onto the thread 11 on the neck 7 of the bottle 1. As shown in FIG. 2 , bottle 1 contains ink 17 . The bottle 1 is preferably a semi-rigid bottle blow molded from a su...

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 also is disclosed.
Description
technical field [0001] The present invention relates to ink bottles (or other containers) for containing ink for use in inkjet printing systems. Inkjet printing equipment using the ink bottle of the present invention is generally referred to as an industrial type inkjet printing system (different from an office inkjet printer), and it is generally used for Markings are printed on product packaging or secondary packaging as it passes through the system's inkjet printheads. One such inkjet printing system is shown in US Patent Application No. 08 / 728,774, filed October 11, 1996, assigned to the Marsh Company of Belleville, Illinois. It should be appreciated that such industrial inkjet printing systems generally use significantly more ink at a given time than office inkjet printers because of the larger area printed by such industrial printers and the fact that industrial printing systems Work continuously. Thus, there is a need to provide such industrial inkjet printers with a...
