Description

Packaging case for ink cartridge

The present invention relates to a packaging case of an ink cartridge, and more particularly, to a packaging case of an ink cartridge having a means for preventing the ink plate from drying out of the nozzle plate of the printhead when receiving the ink cartridge.

In general, an inkjet cartridge for an inkjet printer refers to an apparatus for printing ink and printing an image of a predetermined color on paper by ejecting ink droplets through a print head. In such inkjet cartridges, it is necessary to keep the ink reservoir at a negative pressure to prevent wetting from occurring in the print head when an excessive amount of ink is counted by the head during printing or not being printed.

1 is a side view schematically showing the structure of a conventional ink cartridge.

Referring to FIG. 1, a nozzle plate having a plurality of nozzles 3 through which ink is discharged is formed in a lower part of a main body 1 of an ink cartridge. These nozzles 3 and nozzle plate 2 are also referred to as printheads 2.

At the lower part of the ink cartridge 1, a flexible print circuit (FPC) 4 to which the wires connected to each nozzle 3 are printed is attached around the print head 2. The FPC 4 is installed to extend to the side of the ink cartridge body 1, and a plurality of contacts 5 are formed in the FPC 4 disposed on the side, and these contacts are not shown in the ink cartridge carriage It is energized by being in contact with the contact corresponding to.

On the other hand, the nozzle protection film 6 which masks the surface of the print head 2 in order to prevent the ink in the ink cartridge 1 from leaking through the print head 2 to the outside for carrying the ink cartridge 1 is provided. It is installed. An adhesive 7 is applied to the inside of the nozzle protection film 6.

When using the ink cartridge 1 to which the nozzle protection film 6 is attached for the first time, the nozzle protection film 6 is removed from the ink cartridge 1 by pulling a portion where the adhesive 7 is not applied, and then mounted on the carriage. Can be used.

However, in the case of using the nozzle protection film 6 of the related art, the adhesive 7 may cause the problem of preventing the ink from being discharged by blocking the nozzles 3 of the print head 2. In addition, since the nozzle protection film 6 is a single-use, when the user removes the ink cartridge 1 from the inkjet printer during use and moves to another place, the print head 2 may be opened and ink leakage may occur. Dust, etc., may enter the printhead 2 and cause nozzle clogging.
