1. Ink cartridge (10) for an inkjet printer, comprising a housing (11) which bounds at least one ink chamber (12) and on a bottom side, or base (14), of which there is formed an ink off-take aperture (16) or a connection port including said aperture, an ink supply channel (17) extending over a predetermined height of the connection port, the ink supply channel is formed in the base (14) of the ink cartridge (10) upstream of the ink off-take aperture or the connection port including said aperture for establishing a fluid connection between the ink chamber (12) and a supply connection provided at the inkjet printer via the ink off-take aperture (16) or the connection port (15) including said aperture.
2. Ink cartridge according to claim 1, wherein the ink supply channel (17) extends over at least half to three-quarters of a length of the base.
3. Ink cartridge according to claim 1, wherein the ink supply channel (17) is constructed so that, in use of the ink cartridge, the ink located in the ink supply channel (17) flows to the connection port (15) or ink off-take aperture (16), due to gravity.
4. Ink cartridge according to claim 3, wherein a bottom (19) of the ink supply channel (17) is downwardly inclined in a direction of the connection port (15) or ink off-take aperture (16).
5. Ink cartridge according to claim 1, wherein a cross-section of the ink supply channel (17) has a ratio of width (B) to depth (T) of less than 1, and the ratio decreases in a direction of the connection port (15) or ink off-take aperture (16).
6. Ink cartridge according to claim 1, wherein a cross-section of the ink supply channel (17) reduces from top to bottom.
7. Ink cartridge according to claim 6, wherein the cross-section of the ink supply channel (17) is approximately V-shaped.
8. Ink cartridge according to claim 6, wherein a width (B) at the top of the ink supply channel (17), over which width the channel is in communication with the ink chamber (12), is constant over a length of the channel and is approximately 1.0 to 3.0 mm.
8. Ink cartridge according to claim 6, wherein a width (B) of the ink supply channel (17) at the bottom (19) thereof is between approximately 0.1 mm and 2.00 mm, and the width decreases as a depth (T) of the ink supply channel (17) increases. |
