1. An ink-cartridge for printers comprising a body formed in a predetermined size and 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.
2. The ink-cartridge for printers as set forth in claim 1, wherein the pressure regulating part is communicates with the filling chamber via a plurality of communicating ports.
3. The ink-cartridge for printers as set forth in claim 2, wherein the plurality of the communicating ports are formed in each of the inner space of the filling chamber which is divided by the partition.
4. The ink-cartridge for printers as set forth in claim 1, wherein the pressure regulating part forms a specific space by the blocking film.
5. The ink-cartridge for printers as set forth in claim 1, wherein the blocking film which is attached to the pressure regulating part is in flexible response to difference in pressure between an inside and an outside of the cartridge.
6. The ink-cartridge for printers as set forth in claim 1, wherein at least one the partition is installed.
7. The ink-cartridge for printers as set forth in claim 6, wherein communicating ports of the pressure regulating part are formed in each of the inner space of the filling chamber which is divided by the partition.
8. The ink-cartridge for printers as set forth in claim 1, wherein an ink transferring channel connecting the discharging chamber with the discharging port is formed at an outside of the body.
9. The ink-cartridge for printers as set forth in claim 8, wherein an upper end portion of the ink transferring channel is formed at higher than an upper portion of the uppermost filling chamber.
10. The ink-cartridge for printers as set forth in claim 1, wherein a packing member (41->(not shown)) is embedded in an inside of the discharging port.
11. The ink-cartridge for printers as set forth in claim 1, wherein the air transferring channel connecting the filling chamber with the air chamber is formed in an inside of the body.
12. The ink-cartridge for printers as set forth in claim 1, wherein the air suction valve which is selectively open/close the air chamber is a check valve which is elastically installed so as to be opened in one direction.
13. The ink-cartridge for printers as set forth in claim 1, wherein the air inducing channel inducing air into an inside of the air chamber is formed in an outside surface of the body.
14. The ink-cartridge for printers as set forth in claim 13, wherein an upper end portion of the air inducing channel is formed at higher than an upper portion of the uppermost filling chamber.
15. The ink-cartridge for printers as set forth in claim 13, wherein an end portion of the air inducing channel is formed so as to pass through an upper surface of the body. |
