Abstract

Druckerpatrone für einen Tintenstrahldrucker.Printer cartridge for an inkjet printer.

Gegenstand der Erfindung ist eine Druckerpatrone (1) für einen Tintenstrahldrucker mit einem Behälter zur Aufnahme einer bestimmten Tintenmenge, wobei der Behälter (2) einen Druckkopf (4) zum Auswerfen von Tinte (3) aus dem Behälter (2) und eine Drucksteuereinrichtung (5) zur Steuerung des Unterdruckes im Behälter (2) aufweist und die Drucksteuereinrichtung (5) aus mindestens einem in den Innenraum des Behälters (2) hineinragenden, flexiblen Füllkörper (6) zur Veränderung des Volumens des Behälters besteht.The invention relates to a printer cartridge (1) for an inkjet printer with a container for receiving a certain amount of ink, wherein the Container (2) A printhead (4) for ejecting ink (3) from the container (2) and a pressure control device (5) for controlling the negative pressure in the container (2) and the pressure control device (5) of at least one in the Interior of the container (2) protruding, flexible packing (6) for modification consists of the volume of the container.

Erfindungsgemäß entspricht dabei das maximale Ausdehnungsvolumen des Füllkörpers (6) etwa dem maximalen Füllvolumen der Tinte (3).According to the invention corresponds to the maximum expansion volume of the packing (6) about the maximum filling volume of the ink (3).

Dadurch wird der Druckausgleich innerhalb des Behälters (2) ausschließlich aus einem oder mehreren Füllkörpern (6) bewirkt, so dass das Ansaugen von Außenluft in den Behälter (2) vollkommen entbehrlich ist. Damit wird die Tinte (3) während der gesamten Nutzungsdauer der Druckerpatrone (1) nicht mit zusätzlichem Sauerstoff in Berührung gebracht, wodurch die Lagerfähigkeit der Druckerpatrone (1) beträchtlich vergrößert wird.

Figure 00000001
Thereby, the pressure equalization within the container (2) is effected exclusively from one or more packing elements (6), so that the suction of outside air into the container (2) is completely dispensable. Thus, the ink (3) is not brought in contact with additional oxygen during the entire service life of the print cartridge (1), whereby the storage life of the print cartridge (1) is considerably increased.
