The present invention relates to an ink tank (10), in particular for a printing head of an inkjet printer, having an ink chamber (11) for the uptake of ink (12) the chamber having a removal opening (14) for the ink (12), having an element (20) for slowing down the outflow of ink provided in the region of the removal opening (14) and forming an ink outlet (23) at least in regions, having a tank element (30), which is provided inside the ink chamber (11), the inside space (38) thereof being connected to the ink chamber (11) by means of at least one transfer opening (36) and in which a porous material is provided, and having a ventilation device for the tank element (30). In order to create an ink tank in which the ink chamber can be filled with the maximum amount of ink, whereby an undesired overflow of the ink can simultaneously be prevented, it is provided according to the invention that at least the ink outlet (23) formed by the element (20) for slowing down the outflow of ink is provided at a distance from the removal opening (14) within the ink chamber (11), that the tank element (30) is disposed at least around the ink outlet (23) formed by the element (20) for slowing down the outflow of ink, that the porous material (40) is applied at least at the ink outlet (23) formed by the element (20) for slowing down the outflow of ink, and that the transfer point (37) of ink from the ink chamber (11) into the tank element (30) is provided under the ink outlet (23) formed by the element (20) for slowing down the outflow of ink.
An ink tank, in particular for a printing head of an inkjet printer, having an ink chamber for the uptake of ink, the chamber having a removal opening for the ink, having an element for slowing down the outflow of ink provided in the region of the removal opening in the ink chamber and forming an ink outlet at least in regions, having a tank element, which is provided inside the ink chamber, the inside space thereof being connected to the ink chamber via at least one transfer opening and in which a porous material is provided, and having a ventilation device for the tank element, is hereby characterized in that at least the ink outlet, which is formed by the element for slowing down the outflow of ink and which is distanced from the removal opening, is provided inside the ink chamber, that the tank element is disposed at least around the ink outlet formed by the element for slowing down the outflow of ink, that the porous material is applied at least to the ink outlet formed by the element for slowing down the outflow of ink, and that the transfer point of ink from the ink chamber into the tank element, the transfer point being formed by the transfer opening, is provided under the ink outlet formed by the element for slowing down the outflow of the ink.
