Problems solved by technology

Therefore, the production or manufacturing costs are high, since such cartridges can only be produced under the condition that different parts are manufactured
Moreover, such cartridges cannot be produced without injection molds and without sliding parts, which increases production or manufacturing costs

Embodiment Construction

[0072] The ink cartridge according to the invention for a printer with a print head (not shown) is arranged below the print head at least during printing operations. This arrangement relative to the print head creates a negative pressure at the nozzles of the print head, which is necessary for a sharp printed image.

[0073] Such as figure 1 and 2 The ink cartridge for a printer not shown comprises a cover 1 and, for containing ink, a substantially square ink tank 2 with a bottom 2.1 surrounded by side walls 2.2. The cover 1 is fluid-tightly connected to the side wall 2.2 by means of a snap connection or snap connection. For sealing, a circumferential sealing ring 17 is inserted between the cover part 1 and the side wall 2.2.

[0074] Optionally, the cover 1 can also be welded or glued to the side wall 2.2 in a liquid-tight manner.

[0075] On the side surfaces of the cover 1 there are injection-molded cross pins 4, 5 as means for detachably fixing the ink cartridge in a n...

Abstract

The invention relates to an ink tank for a printer having a print head, wherein the ink tank contains an extraction opening (23) for connection to the print head and, for receiving ink, has a trough (2) with a base (2.1) and side walls (2.2) and a lid (1) which is placed onto the side walls (2.2) and has a ventilation opening (6). In order to develop an ink tank of simple design for a printer, with which a constant vacuum can be realized in the ink tank, it is proposed that at least one intermediate wall (24) which is connected to the base (2.1) is arranged in the trough (2) transversely withrespect to the movement direction of the ink tank during the printing process, wherein the intermediate wall (24) has an aperture (18).

Description

technical field [0001] The present invention relates to an ink cartridge for an inkjet printer, wherein, for connection with a print head, the ink cartridge includes a suction hole, and for containing ink, the ink cartridge has an ink tank with a bottom and side walls and an ink tank mounted on A cover with ventilation holes on the side wall, wherein at least one partition wall connected to the bottom is provided in the ink tank, which is arranged in the ink tank transversely to the direction of movement of the ink tank during printing , and the partition has a gap. Background technique [0002] The most common inkjet printers in practice are serial printers with a printer housing in which slides are arranged parallel to the printing line direction. Mounted on the carriage is a replaceable or detachable ink container and a print head, often rigidly connected thereto. When the serial printer is in operation, the print head and the ink container move across on the slide betw...
