BACKGROUND OF THE INVENTION




The present invention relates to ink-jet printing systems, and more particularly, ink-jet printing systems which make use of ink containers that are replaceable separate from a printhead.




Inkjet printers frequently make use of an ink-jet printhead mounted to a carriage which is moved back and fourth across a print media, such as paper. As the printhead is moved across the print media, a control system activates the printhead to eject or jet ink droplets onto the print media to form images and text.




Previously used printers have made use of an ink container that is separably replaceable from the printhead. When the ink cartridge is exhausted the ink cartridge is removed and replaced with a new ink container. The use of replaceable ink containers that are separate from the printhead allow users to replace the ink container without replacing the printhead. The printhead is then replaced at or near the end of printhead life and not when the ink container is exhausted.




One type of ink container spaced from the printhead is disclosed in U.S. Pat. No. 4,558,326 entitled “Purging System for Ink Jet Recording Apparatus” to Kimura et al. discloses the use of a replaceable ink cartridge having a hermetically sealed ink container bag disposed therein. Kimura makes use of the selective application of compressed air to the ink cartridge for pressurizing the ink container bag for forcing ink through a recording head thereby purging bubbles or solid matter from the ink flow path. Another type of ink cartridge is disclosed in U.S. Pat. No. 4,568,954 entitled “Ink Cartridge Manufacturing Method and Apparatus” to Rosback. The Rosback cartridge is a replaceable ink cartridge that is pressurizable.




There is an ever present need for ink containment systems that are capable of providing ink at high flow rates to a printhead thereby allowing high throughput printing. This ink supply system should be cost effective to allow relatively low cost per page printing. In addition, the ink supply should be capable of providing ink at high flow rates in a reliable manner to the printhead.




These ink supplies should be easily replaceable as well as form reliable fluid connection with the printing device while minimizing or eliminating ink spillage which can reduce the reliability of the printing device. The ink supply should be capable of forming additional interconnects such as electrical as well as pressurized gas interconnects between the printing device and the ink container.




SUMMARY OF THE INVENTION




A replaceable ink container for providing ink to a printing device. The ink container has leading and trailing edges with respect to an insertion direction for the ink container into the printing device. The ink container includes a fluid outlet disposed on the leading edge and configured for connection to corresponding printing device fluid inlet. The ink container also includes an engagement feature disposed toward the trailing edge and extending outwardly from an ink container outer surface. The engagement feature is configured for insertion into a recessed engagement feature associated with the printing device. With the ink container properly positioned within the printing device and biased in a direction opposite the insertion direction, the engagement feature associated with the ink container engages the recessed engagement feature associated with the printing device. The engagement of the engagement features on each of the ink container and printer maintain the fluid outlet in engagement with corresponding printing device fluid inlet.




In one preferred embodiment the engagement feature associated with the ink container extends downwardly relative to a gravitational frame of reference. In this preferred embodiment the recessed engagement feature associated with the printing device defines a hook that is configured for engaging the engagement feature associated with the ink container. In this embodiment the ink container includes a pressurized gas inlet electrical contacts for connection with corresponding gas outlet and electrical contacts, respectively, associated with the printing device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT





FIG. 1

depicts a schematic representation of a printing system, printing device or printer


10


which includes the ink container


12


of the present invention. Also included in the printing device


10


is a printhead


14


and a source of pressurized gas such as a pump


16


. The pump


16


is connected by a conduit


18


for providing a pressurized gas such as air to the ink container


12


. A marking fluid


19


such as ink is provided by the ink container


12


to the printhead


14


by a conduit


20


. This marking fluid is ejected from the printhead


14


to accomplish printing.




The ink container


12


which is the subject of the present invention includes a fluid reservoir


22


for containing ink


19


, an outer shell


24


, and a sealing portion or cap


26


. In the preferred embodiment the cap


26


includes an air inlet


28


configured for connection to conduit


18


for pressurizing the outer shell


24


with air. A fluid outlet


30


is also included in the cap


26


. The fluid outlet


30


is configured for connection to the conduit


20


for providing a fluid connection between the fluid reservoir


22


and fluid conduit


20


.




In the preferred embodiment the fluid reservoir


22


is formed from a flexible material such that pressurization of the outer shell produces a pressurized flow of ink from the fluid reservoir


22


through the conduit


20


to the printhead


14


. The use of a pressurized source of ink in the fluid reservoir


22


allows for a relatively high fluid flow rates from the fluid reservoir


22


to the printhead


14


. The use of high flow rates or high rates of ink delivery to the printhead make it possible for high throughput printing by the printing system


10


.




In the preferred embodiment, the ink container


12


also includes a plurality of electrical contacts, as will be discussed in more detail with respect to FIG.


3


. The electrical contacts provide electrical connection between the ink container


12


and printer control electronics


32


. The printer control electronics


32


controls various printing system


10


functions such as, but not limited to, printhead


14


activation to dispense ink and activation of pump


16


to pressurize the ink container


12


. In one preferred embodiment the ink container


12


includes an information storage device


34


and an ink level sensing device or ink volume sensing decice


36


. The information storage device


34


provides information to the printer control electronics for controlling printer


10


parameters such as ink container


12


volume as well as ink characteristics, to name a few. The ink level sensing device


36


provides information relating to current ink volume in the ink container


12


to the printer control electronics


32


.





FIG. 2

depicts one embodiment of the printing system


10


shown in perspective. The printing system


10


includes a printing chassis or printer chassis


38


containing one or more ink containers


12


of the present invention. The embodiment shown in

FIG. 2

is shown having four similar ink containers


12


. In this embodiment, each ink container contains a different ink color. Therefore, four color printing is accomplished by providing cyan, yellow, magenta and black ink from the four ink containers


12


to one or more printheads


14


. Also included in the printer chassis


38


is a control panel


40


for controlling operation of the printer


10


and a media slot


42


from which print media such as paper is ejected.




As ink


19


in each ink container


12


is exhausted the ink container


12


is replaced with a new ink container


12


containing a new supply of ink. In addition, the ink container


12


may be removed from the printer chassis


38


for reasons other than an out of ink condition such as changing inks for an application requiring different ink properties or for use on different media. It is important that the ink container


12


be not only accessible within the printing system


10


but also easily replaceable. It is also important that the replacement ink container


12


form reliable mechanical engagement with the printer chassis


38


as well as properly form necessary interconnects such as fluid interconnect, air interconnect and electrical interconnect so that the printing system


10


performs reliably. The present invention is directed to a method and apparatus for reliably engaging the ink container


12


into the printer chassis


38


to insure proper interconnections are formed. The present invention provides an engaging system that is positive and provides tactile feedback to the user indicating the ink container


12


is properly inserted and secured within the print chassis


38


.




It is important that ink spillage and spattering be minimized to provide reliable interconnection between the ink container


12


and printer


10


. Ink spillage is objectionable not only for the operator of the printer who must handle the spattered ink container


12


but also from a printer reliability standpoint. Inks used in ink-jet printing frequently contain chemicals such as surfactants which if exposed to printer components can effect the reliability of these printer components. Therefore, ink spillage inside the printer can reduce the reliability of printer components thereby reducing the reliability of the printer.





FIGS. 3 and 4

depict the ink container


12


of the present invention. The ink container


12


includes a housing or outer shell


24


which contains the fluid reservoir


22


shown in

FIG. 1

for containing ink


19


. The outer shell


24


has a leading edge


50


and trailing edge


52


relative to a direction of insertion for the ink container


12


into the printer chassis


38


. The leading edge


50


includes the air inlet


28


and the fluid outlet


30


which are configured for connection to the air pump


16


and the printhead


14


, respectively, once the ink container


12


is properly inserted into the printer chassis


38


. The air inlet


28


and fluid outlet


30


will be discussed in more detail with respect to

FIG. 8. A

plurality of electrical contacts


54


are disposed on the leading edge


50


for providing electrical connection between the ink container


12


and printer control electronics


32


. In one preferred embodiment the plurality of electrical contacts


54


include a first plurality of electrical interconnects that are electrically interconnected to the information storage device


34


and a second plurality of electrical interconnects which are electrically interconnected to the ink volume sensing device


36


shown in FIG.


1


. In the preferred embodiment the information storage device


34


is a semiconductor memory and the ink volume sensing device


36


is an inductive sensing device.




The ink container


12


includes one or more keying and guiding features


58


and


60


disposed toward the leading edge


50


of the ink container


12


. The keying and guiding features


58


and


60


work in conjunction with corresponding keying and guiding features on the printer chassis


38


to assist in aligning and guiding the ink container


12


during insertion of the ink container


12


into the printer chassis


38


. The keying and aligning features


58


and


60


in addition to providing a guiding function also provide a keying function to insure only ink containers


12


having proper ink parameters such as proper color and ink type are inserted into a given slot of the printer chassis


38


. Keying and guiding features are discussed in more detail in co-pending patent application Ser. No. 08/566,521 filed Dec. 4, 1995 entitled “Keying System for Ink Supply Containers” assigned to the assignee of the present invention and incorporated herein by reference.




Latch features


62


are provided toward the trailing edge


52


of the ink container


12


. The latch features


62


which are the subject of the present invention work in conjunction with corresponding latching features on the printer portion to secure the ink container


12


within the printer chassis


38


such that proper interconnects such as pressurized air, fluidic and electrical are accomplished in a reliable manner. Each latch feature


62


is a molded tang which extends downwardly relative to a gravitational frame of reference. The ink container


12


shown in

FIG. 4

is positioned for insertion into a printer chassis


38


along the Z-axis of coordinate system


64


. In this orientation gravitational forces act on the ink container


12


along the Y-axis.




At the trailing edge


52


of the ink container


12


is a flanged outer portion


66


which provides several functions. Firstly, the flanged portion


66


is larger than the insertion slot within the printer chassis


38


thereby preventing the ink container


12


from backward insertion. In addition, the flanged portion


66


provides a gripping portion for insertion of the ink container


12


into the printer chassis


38


.





FIG. 5

depicts an ink container


12


of the present invention shown secured within an ink container receiving station


72


within the printer chassis


38


. Because ink container


12


is similar except for keying and guiding features


58


and


60


and corresponding ink properties contained within the respective fluid reservoir, the same reference numbering will be used for each ink container


12


. An ink container indicia


70


may be positioned proximate each slot in the ink container receiving station


72


. The ink container indicia


70


may be a color swatch or text indicating ink color to assist the user in color matching for inserting the ink container


12


in the proper slot within the ink container receiving station


72


. As discussed previously the keying and guiding features


58


and


60


shown in

FIGS. 3 and 4

prevent ink containers from being installed in the wrong slot. Installation of an ink container in the wrong slot can result in improper color mixing or the mixing of inks of different ink types each of which can result in poor print quality.




Each receiving slot within the ink container receiving station includes a corresponding keying and guiding slot


74


and recessed latching portions or latching features


76


. The guiding slot


74


cooperates with the keying and guiding features


58


and


60


to guide the ink container


12


into the ink container receiving station


72


. The keying and guiding slot


74


associated with the corresponding keying and guiding feature


60


is shown in FIG.


5


and the keying and guiding slot associated with the corresponding keying and guiding feature


58


on the ink container


12


is not shown. The latching features


76


are configured for engaging the corresponding latch features

12


as will be discussed in more detail with respect to

FIGS. 6

,


8


and


9


.





FIG. 6

shows a cross-section of a single ink container receiving slot within the ink container receiving station


72


. The ink container receiving slot includes interconnect portions for interconnecting with the ink container


12


. In the preferred embodiment these interconnect portions include a fluid inlet


80


, and air outlet


82


and an electrical interconnect


84


. Each of the interconnects


80


,


82


,


84


are positioned on a floating interconnect portion


86


which is biased along the Z-axis toward the installed ink container


12


.




The fluid inlet


80


and the air outlet


82


associated with the ink container receiving station


72


are configured for connection with the corresponding fluid outlet


30


and air inlet


28


, respectively on the ink container


12


. The electrical interconnect


84


is configured for engaging the plurality of electrical contacts


54


on the ink container


12


.




It is the interaction between the keying and guiding features


58


and


60


associated with the ink container


12


and the corresponding keying and guiding feature


74


associated with the ink container receiving station


72


which guide the ink container


12


during the insertion such that proper interconnections are accomplished between the ink container


12


and the printer chassis


38


. In addition, sidewalls associated with each slot in the ink container receiving station


72


engage corresponding sidewalls of the outer shell


24


of ink container


12


to assist in guiding and aligning the ink container


12


during insertion into the ink container receiving station


72


.





FIG. 7

illustrates further detail of the fluid outlet


30


and air inlet


28


associated with the ink container


12


and the corresponding fluid inlet

opposite the lateral hole


94


is connected to the fluid conduit


20


for providing ink to the printhead


14


shown in

FIG. 1. A

sliding collar


96


surrounds the needle


92


and is biased upwardly by spring


98


. The sliding collar


96


has a compliant sealing portion with an exposed upper surface and an inner surface in direct contact with the needle


92


.




The air outlet


82


on the ink container receiving station


72


is similar to the fluid inlet


80


. The air outlet


82


on the ink container receiving station


72


includes a housing


100


and outwardly extending needle


102


having a closed, blunt upper end, a blind bore (not shown) and a lateral hole

102


and is biased upwardly by spring


108


. The sliding collar


106


has a compliant sealing portion with an exposed upper surface and an inner surface in direct contact with the needle


102


. Alternatively, the sliding collar


106


and spring


108


can be eliminated because a fluid seal is not required at the air interface.




In this preferred embodiment, the fluid outlet


30


associated with the ink container


12


includes a hollow cylindrical boss


110


that extends outward from an ink container chassis


112


. The end of the boss


110


toward the chassis


112


opens into a conduit


114


which is fluidly connected to the ink reservoir


22


thereby providing fluid to the fluid outlet


30


. A spring


116


and sealing ball


118


are positioned within the boss


110


and held in place by a compliant septum


120


and a crimp cover


122


. The spring


116


biases the sealing ball


118


against the septum


120


to form a fluid seal.




In the preferred embodiment, the air inlet


28


associated with the ink container


12


is similar to the fluid outlet


30


except that the additional seal formed by the spring


116


and sealing ball


118


are eliminated. The air inlet


28


associated with the ink container


12


includes a hollow cylindrical boss


124


that extends outward from an ink container chassis


112


. The end of the boss


124

112


opens into a conduit


126


which is in communication with a region between the outer shell


24


and an outer portion of the fluid reservoir


22


for pressurizing the fluid reservoir


22


. A compliant septum


128


and a crimp cover


130


form a seal.




The insertion of the ink container


12


into the ink container receiving station


72


will now be discussed with respect to

FIGS. 8A

,


8


B,


8


C, and


8


D. As shown in

FIG. 8A

the ink container


12


is inserted along an insertion direction corresponding to the Z-axis in coordinate system


64


. During insertion the guiding and keying features


58


and


60


associated with the ink container


12


in conjunction with guiding and keying features


74


associated with the ink container receiving station


72


guide and align the proper ink container


12


into the ink container receiving station.




As shown in

FIG. 8B

the keying and guiding features


58


and


60


associated with the ink container


12


together with the keying and guiding features


74


associated with the ink container receiving station


72


align and guide the ink container


12


so that the fluid outlet


30


and air inlet


28


engage the corresponding fluid inlet


80


and air outlet


82


, respectively, associated with the ink container receiving station


72


.




As the ink container


12


is inserted into the ink container receiving station


72


the crimp caps


122


and


130


are guided into the internal bores of housings


90


and


100


, respectively, by the keying and guiding features


58


,


60


and


74


. As the ink container


12


is further inserted, the alignment of the ink container


12


within the ink container receiving station


72


is then defined by the leading edge or crimp caps


122


and


130


and the internal bores of the housings


90


and


100


, respectively. As the ink container


12


is pushed inward or sideways, along the z axis of coordinate system


64


, into the receiving station


72


the crimp caps


122


and


130


engage the sealing members


96


and


106


, respectively, compressing springs


98


and


108


.




During insertion of the ink container


12


into the ink container receiving station


72


, the outwardly extending needles


92


and


102


pierce the septums


120


and


128


, respectively of the fluid outlet


30


and air inlet


28


, receptively, of ink container


12


. As needle


92


pierces the septum


120


of fluid outlet


30


and displaces the sealing ball


118


a fluid flow path is established from the ink reservoir


22


into the lateral hole


94


of the needle


92


through the blind bore and into the fluid conduit


20


to the printhead


14


. Similarly, as needle


102


pierces the septum


128


of air inlet


28


an air flow path is established between the air pump


16


to a region between the ink container outer shell


24


and ink reservoir


22


.




Once the ink container


12


is inserted into the ink container receiving station


72


such that the latch features


62


on the ink container


12


moves past the latching features


76


associated with the ink container receiving station


72


as shown in

FIG. 8C

, the ink container


12


drops downward along the y axis. As the ink container


12


drops down the springs


98


and


108


bias the ink container


12


in a direction opposite the insertion direction into a latched position such that the latch features (i.e. engagement features)


62


on the ink container


12


engage the latching features (i.e. recessed engagement features)


76


associated with the receiving station


72


as shown in FIG.


8


D. In addition, the floating interconnect portion


86


is spring biased along the Z-axis opposite the insertion direction. Therefore, this spring force together with springs


98


and


108


tends to bias the ink container


12


such that the engagement features


62


and


76


engage.




The latch feature


62


is shown partially broken away to more clearly show the engagement of engagement features


62


and


76


. Once in the latched position the ink container


12


is firmly secured in the ink container receiving station


72


. In this latched position fluid communication between the fluid outlet


30


and fluid inlet


80


is established and communication between the air outlet


82


and air inlet


28


is established. In addition, in the latched position electrical connection is established between the plurality of electrical contacts


54


associated with the ink container


12


and the electrical interconnact


84


associated with the ink container receiving station


72


.





FIGS. 9A

,


9


B,


9


C and


9


D illustrates the removal of ink container


12


from the printer chassis


38


.

FIG. 9A

shows the ink container in a latched position within the ink container receiving station


72


. The application of a force at an upper portion


136


of the trailing edge


52


of the ink container


12


identified by a circular depression is used to release the ink container


12


. This force, when applied in a direction along the direction of insertion, urges the ink container


12


inwardly, compressing springs


98


and


108


, and moving the engagement feature


62


inwardly and away from the engagement feature
