Embodiment Construction

[0014] exist figure 1 and 2 The ink cartridge shown schematically in is marked with the reference numeral 10 . The cartridge comprises four side walls, more precisely two opposing flat side walls 11 and two opposing end side walls 12 , and a cover wall 13 and a bottom wall 14 . The cover wall 13 is formed by a separate cover which is glued or welded to the upper edges of the side walls of the ink cartridge after the ink storage element forming the capillary volume 15 has been assembled inside the ink cartridge. The ink storage element constituting the capillary volume 15 may consist of a foam material or a fibrous material with open pores. This is a measure known per se, which need not be described in detail here. The chamber 18 delimiting the aforementioned capillary volume is in fluid communication with another chamber 17 , which delimits the so-called free ink volume 16 , via a passage 19 near the bottom. That is, liquid ink exists in the cavity 17 . The two chambers 1...

Abstract

The invention relates to an ink cartridge (10) with an ink reservoir which delimits a free ink volume (16) in a first compartment (17) and a capillary volume (15) in a second compartment (18), an ink outlet (21) being associated with the capillary volume and both compartments (17, 18) being connectible to the exterior via ventilation holes (23, 24) for use of the cartridge. Said ventilation holes are closed prior to use by means of a removable or peelable film (25). The ventilation holes (23, 24) are arranged relative each other in such a manner that it is always the compartment (18) delimiting the capillary volume (15) that is ventilated first when the remove film (25) is peeled off.

Description

technical field [0001] The invention relates to an ink cartridge, in particular for an inkjet printer, comprising an ink reservoir delimiting a free ink volume in a first chamber and a capillary volume in a second chamber, wherein said The capillary volume is provided with an ink outlet, and for the use of the ink cartridge, the two chambers can communicate with the external environment through vent openings, each of which is removed or pulled or so-called removable before use. Remove film closure. Background technique [0002] Such dual chamber ink cartridges are known. One of the chambers is filled with liquid ink, while the other chamber is filled with an ink storage element such as a sponge or the like. There is a fluid connection between the two chambers, so that the storage element always supplies enough ink to the ink outlet associated with it, that is, supplies ink until the ink is substantially used up. In use, these two chambers must be connected to the external...
