Problems solved by technology

[0007] However, in this conventional ink cartridge, since the sponge 210 soaked with ink is embedded in the body 200, the problem is that due to the increased The process of embedding the sponge 210 in the middle increases the manufacturing cost, and also makes the space size for filling the ink smaller
[0008] The sponge 210 can be removed from the body 200 to solve the above-mentioned problem, but another problem is that when the ink cartridge is installed in the head, micro-bubbles are generated in the ink due to the free moveme...

The present invention relates to an ink-cartridge for printers comprising a body formed having a filling hole on an upper surface thereof; a plurality of filling chambers inside of the body divided by a partition having a connecting hole; a discharging chamber connected to the filling chamber; an air chamber connected to the filling chamber via an air transferring channel so as to supply air to the filling chamber; an air suction valve installed in the air chamber; an air inducing channel inducing external air to the air suction valve; a blocking film attached to one surface of the body; and a cover installed in the other surface of the body; and a pressure regulating part formed in a surface of an outer wall of the body and communicating with the filling chamber.

Description

technical field [0001] The present invention relates to an ink cartridge for a printer, and more particularly, to an ink cartridge for a printer in which a space filled with ink is enlarged so that air bubbles and reverse flow of the ink due to free movement of the ink can be prevented. Background technique [0002] Generally, a printer is used as a device for outputting a document created with a computer or a picture drawn on paper, and the printer includes a dot matrix printer, an inkjet printer, and a laser printer; as figure 1 As shown, the inkjet printer 100 is provided with: a cartridge feeder 110 movably installed in the printer 100, and the cartridge feeder 110 has a space for removably installing an ink cartridge 120; a needle for sucking ink filled in the ink cartridge 120 111; and a head 112 that ejects the ink delivered by the needle. [0003] Although the shape and structure of the ink cartridges differ depending on the type of printer, if figure 1 As shown, t...
