Definitions
- the present invention relates to an ink cartridge, in particular for an inkjet printer, having an ink reservoir which limits a free ink volume in a first chamber and a capillary volume in a second chamber, wherein the two chambers are ventilated via one opening and fluidly connected to each other via a passage, and wherein the capillary volume limiting chamber is associated with an ink outlet.
- One chamber serves to hold liquid or so-called free ink, while the other chamber limits a capillary volume of sponge, fibrous or the like storage material.
- This chamber is also associated with the ink outlet to the printer or a printhead.
- both ink chambers are ventilated via separate openings, i. connectable with the external environment to provide pressure equalization in and between the two chambers, which ensures a functionally safe use of the ink cartridge.
- the free ink volume limiting chamber may preferably communicate with the outside environment via a bubble generator.
- the capillary volume defining material e.g. Sponge or fiber material
- the capillary volume defining material is compressed during assembly in the associated chamber of the ink cartridge, so that the material fills all corners and edges of the chamber. This is intended to prevent ingress of ambient air into the free ink volume limiting chamber.
- the sponge or fiber material is not placed very accurately, more or less large air channels, through which ambient air can pass to the fluid passage between the two chambers and thus into the free ink volume limiting chamber. It is also conceivable that ambient air finds a way through a partially emptied capillary volume to the free ink volume limiting chamber.
- the present invention is based on the object to provide an ink cartridge of the type mentioned, in which compared to the prior art, a much greater security against the ingress of ambient air through the capillary volume limiting chamber through the free ink volume limiting chamber into it.
- An essential basic idea of the present invention therefore lies in assigning capillary-increasing means, which define a kind of "air barrier", to the passage between the two chambers on the side facing the capillary volume, thus ensuring that the chamber delimiting the free-ink volume passes through the chamber
- Chamber associated B aeration opening in a predetermined manner that is ventilated in a functionally reliable manner when using the cartridge.
- this ensures that a free-volume ink associated with the bubble generator works properly until complete emptying of the free ink chamber, so that subsequently the Kapillarvolumen limiting chamber can be emptied without ambient air from the free ink chamber through the fluid connection between the two chambers in the capillary can penetrate.
- the capillary volume limiting chamber should take place until completely drained via the ventilation opening assigned to this chamber.
- the ventilation of the two chambers should be exclusively via the ventilation openings associated with these chambers, which are ventilated for the purpose of complete emptying of the cartridge or for the purpose of a predetermined successive emptying of the two chambers in a coordinated manner.
- This co-ordinated ventilation should be maintained from the first use to the complete emptying of the cartridge.
- a preferred embodiment of the construction according to the invention is characterized in that a rib extends around the capillary volume on the side of the fluid passage between the two chambers, which rib penetrates into the capillary volume or into the sponge or fiber material defining the capillary volume. This results in a local compression of the capillary volume defining material with the consequence of a corresponding increase in capillarity in this area. This increased capillarity forms the desired "air barrier".
- the capillary volume at the side facing the passage between the two chambers with a capillary-increasing insert which extends at least partially around the passage.
- the capillary increase is thus carried out in this embodiment not by measures on the ink cartridge or the housing thereof, but by local change of the Kapillarvolumen defining material.
- a particularly preferred embodiment which is also relatively easy to manufacture, is characterized in that the passage is formed in a partition wall between the two chambers, starting from the bottom or the bottom wall of the cartridge, and that in the capillary protruding rib is approximately U-shaped and limits the passageway archway-like.
- the legs adjacent to the bottom wall may then preferably be on the inside, i. the side facing the capillary volume may be continued over the corner, forming so-called bottom ribs.
- the passage is bounded by two or more spaced apart and each extending parallel to each other ribs, in this embodiment, the height of these ribs either equal or preferably in
- Figure 1 is an ink cartridge in a perspective view obliquely from above, on which the measures according to the invention are made.
- FIG. 2 shows the ink cartridge according to FIG. 1 in longitudinal section
- FIG. 1 in a view corresponding to FIG. 1, but with a broken away flat or longitudinal side wall showing the measures according to the invention.
- the ink cartridge shown in Figures 1 to 3 is indicated by the reference numeral 10. It comprises two opposing flat or longitudinal side walls 11, two opposite end walls 12, a top wall 13 and a bottom wall 14. Furthermore, the aforementioned ink cartridge on an ink reservoir, which in a first chamber 17 a free ink volume 16 and in a second chamber 18 a Capillary volume 15 limited, wherein the two chambers 17 and 18 are each ventilated via an opening 23, 24 and fluidly connected to each other via a passage 22.
- the capillary volume 15 bounding chamber 18 is associated with an ink outlet 21.
- the capillary volume 15 is formed by a storage element of sponge or fiber material.
- the ink outlet 21 is also associated with a sponge or fiber material which has a higher capillarity than the capillary volume 15. This capillary element associated with the ink outlet 21, which is sometimes referred to as a "wick", is identified by the reference numeral 27 in FIG ,
- both chambers 17 and 18 are associated with ventilation openings 23, 24. These ventilation openings are arranged in each other in the illustrated embodiment.
- An inner ventilation opening 23 is connected via an air duct 25 formed in the cover wall 13 to an opening 28 opening into the free ink volume limiting chamber 17, which in turn communicates with a bubble generator 19 immersed in the free ink volume.
- the central opening 23 is annularly surrounded by an outer ventilation opening 24. This is via a likewise formed in the top wall 13 air duct 26 with a in which the Kapillarvolu- men bordering chamber 18 opening opening 29 connected.
- both chambers 17 and 18 are ventilated independently of one another, after a so-called "remove film” 30 has been removed from the two openings 23, 24 prior to the first use of the cartridge 10. This removal film 30 also serves to cover the ink. Ten outlet 21 and is also deducted from this before the first use of the cartridge 10.
- the opening 28 communicates with the so-called bubble generator 19, which is a dip tube immersed in the free ink volume.
- bubble generator 19 is a dip tube immersed in the free ink volume.
- At the lower or distal end of this dip tube at least one slot-shaped opening is formed, through which air can be sucked into the chamber 17 during the use of the ink cartridge due to the aspiration of ink, forming air bubbles.
- the function of the bubble generator 19 is very important for the complete emptying of the ink cartridge, especially for the successive emptying of the same. First, it is necessary to empty the free ink volume limiting chamber 17 to then suck residual ink from the capillary.
- capillary increasing means are assigned to the capillary volume 15 side facing, in the form of a passage 22 surrounding the arch-like rib 32nd (see Figures 2 and 3).
- This rib 32 protrudes into the capillary volume 15 and locally compresses this or the sponge or fiber material defining the capillary volume 15, thereby forming an increased capillarity, whereby a corresponding air barrier is formed.
- the rib 32 is therefore approximately U-shaped and directly adjacent to the peripheral edge of the passage 22.
- the legs 33, adjacent the bottom wall 14, of the passage-limiting rib 32 are on the inside, i. the capillary volume 15 facing side continued over corner to form so-called bottom ribs 34. Accordingly, the capillarity is increased substantially completely around the passage 22 in the aforementioned manner.
- the height of the bottom ribs 34 decreases in a preferred embodiment, starting from the passage 22 in the direction away from this steadily. Even a gradual decrease in height is conceivable.
- the cross section of the passage 22 bounding rib 32 is preferably approximately semicircular. However, it is also a triangular or trapezoidal cross-section conceivable. In principle, it is also conceivable to arrange a transverse rib projecting into the capillary volume at the lower end of the two legs 33 of the U-shaped rib 32 adjoining the inside of the bottom wall 14, so that the passage 22 is surrounded by the rib 32 in a substantially annular manner.
- capillary-increasing means on the material defining the capillary volume 15 or to provide this material with capillary-increasing means corresponding to the passage 22 assigned. This can be done by a capillary-increasing insert associated with the passageway 22 between the two chambers 17 and 18, which extends at least partially around the passage 22 and is defined by a material of higher density or smaller pore size.
