Definitions
- Ink cartridges used in inkjet printers typically comprise a vent that allows air to enter the cartridge as ink is drawn from the cartridge.
- the passage of such air into the cartridge avoids the creation of a vacuum within the cartridge and, therefore, facilitates the flow of ink from the cartridge.
- vent of an ink cartridge is normally sealed prior to use to avoid evaporation of the ink contained within the cartridge and leakage from the vent due to pressure changes during shipment.
- the vent is covered by a sealing member that the end user removes prior to installing the cartridge within a printer.
- sealing members are held in place with pressure sensitive adhesive.
- such adhesive exhibits high rates of failure, particularly when the adhesive is exposed to higher temperatures and/or altitudes. When the adhesive fails, air can then enter the cartridge and dry out the ink that the cartridge contains.
- EP 1 449 666 A1 discloses an ink reservoir having a body and a cover disposed on the body.
- a vent is disposed in the cover.
- the vent has a vent hole passing through the cover and an elongated vent path that communicatively couples the vent hole to an atmosphere surrounding an exterior of the ink reservoir.
- a membrane is disposed over the vent hole for acting to repel ink therefrom and for allowing air flow through the membrane and the vent.
- ink cartridge vents may be sealed using a sealing member that is attached to the cartridge with pressure sensitive adhesive.
- pressure sensitive adhesive can be accompanied by high rates of failure, particularly when the adhesive is exposed to higher temperatures and/or altitudes.
- lower rates of failure can be achieved when the sealing member is heat staked to the cartridge. Because the heat staking process can raise the temperature of air contained within the cartridge and therefore can cause that air to expand, heat staking may be performed in a multi-stage process in which the vent is not fully sealed until a final stage of heat staking. In such a case, air may escape from the cartridge during the heat staking process.
- heat stake elements used in the heat staking process maintain air gaps between the sealing member and the cartridge that provide pathways for the air to escape.
- the ink cartridge 10 that is configured to contain and supply ink to a printing device, such as a printer.
- the ink cartridge 10 comprises a polymeric body 12 that, for example, is formed through injection molding.
- the body 12 includes a front side 14, a rear side 16, a top side 18, a bottom side 20, and opposed lateral sides 22 and 24.
- Extending upward from the bottom end of the front side 14 is a finger tab 26 that may be used to insert the cartridge 10 into and/or remove the cartridge from a printing device.
- Extending downward from the bottom side 20 is an ink outlet 28 from which ink may be drawn from the cartridge 10.
- a sealing member 30 that is used to seal an air vent (not visible in FIGs. 1 and 2 ) provided on the top side of the cartridge 10 that enables air to enter and exit the cartridge.
- the sealing member 30 is printed upon with various indicia, such that the sealing member also functions as a label. Examples of indicia that may be printed upon the sealing member 30 include indications of the cartridge manufacturer, the cartridge model number, the cartridge manufacturing date, and the like.
- the sealing member 30 comprises a thin strip of polymeric material.
- the sealing member 30 is heat staked to the cartridge 10. More particularly, the sealing member 30 is heat staked to the surface of the top side 18 at discrete locations. In addition, the sealing member 30 is adhered to the cartridge 10 with adhesive. In some embodiments, thermal adhesive is provided along the entire length of the sealing member 30 and pressure sensitive adhesive is provided at discrete locations that do not coincide with an air vent described below. As is further illustrated in FIGs. 1 and 2 , the sealing member 30 further includes tear slits 34 that facilitate intentional tearing of the sealing member at a predetermined point along its length to expose the vent to the ambient air.
- the portion of the sealing member 30 that extends from its end 36 to the tear slits 34 therefore comprises a tear-away portion 38 of the sealing member that may be removed by the user prior to use of the cartridge 10.
- the tear-away portion 38 is torn away using an end portion 32 of the sealing member 30 that is not adhered to the cartridge 10 and, therefore, serves as a pull tab.
- FIG. 3 illustrates an example embodiment of an air vent 50 provided on the top side 18 of the cartridge 10.
- the vent 50 comprises a labyrinth vent that includes a vent opening 52 provided within a circular recess 54 that is in fluid communication with an elongated vent channel 56.
- the channel 56 comprises a serpentine channel section 58 that extends from the recess 54 to an linear channel section 60.
- the channel 56 terminates in a T-shaped end 62 that, as described below, is exposed when the tear-away portion 38 of the sealing member 30 is removed by the end user.
- multiple heat stake elements 64 are provided on a surface 66 that defines the upper edges of the circular recess 54 and the vent channel 56.
- the heat stake elements 64 comprise small cylindrical elements that are unitarily formed with the top side 18 of the cartridge 10. Although cylindrical elements have been illustrated and described, it is to be understood that the heat stake elements 64 may comprise other shapes, including cones, rounded domes, ribs, and the like. In some embodiments, the heat stake elements 64 are approximately 30 to 500 microns ( ⁇ m) tall. By way of example, the heat stake elements 64 are approximately 200 ⁇ m tall.
- the example cartridge 10 shown in FIG. 3 comprises seven heat stake elements 64, including a first pair of elements positioned on opposite sides of the circular recess 54, a second pair of elements positioned on opposite sides of the linear channel section 60, a lone element positioned within the last curve of the serpentine channel section 58 prior to the linear channel section, and a pair of elements 68 that are positioned on opposite sides of an intermediate portion of the serpentine channel section. It is noted that greater or fewer heat stake elements 64 can be used/or can be positioned in alternative position as required for the particular cartridge application. As described below, the heat stake elements 68 may be the last elements to be bonded to the sealing member 30, in which case the elements 68 enable venting of air out from the cartridge 10 during previous stages of the heat staking process.
- FIG. 4 illustrates the sealing member 30 in place over the air vent 50 prior to heat staking.
- the sealing member 30 is adhered to the top side 18 and the rear side 16 of the cartridge 10 and covers both the circular recess 54 and the vent channel 60, including the T-shaped end 62.
- the sealing member 30 is not adhered to the cartridge along its entire length.
- the portion of the sealing member 30 that overlies the air vent 50 is not adhered to the cartridge 10 because that portion of the member only comprises thermal adhesive that has not yet been heated.
- FIGs. 5A-5C depict various stages of a multi-stage heat staking process in which multiple heat staking dies are brought into contact with the cartridge 10 and its sealing member 30. More particularly, illustrated in FIGs. 5A-5C are outlines of the footprints of three different dies to identify the heat stake elements 64, 68 upon which they act. Referring first to FIG. 5A , a first die 70 is used to apply heat to the three heat stake elements 64 closest to the T-shaped end 62 and the two heat stake elements circular recess 54. Notably, the die 70 does not overlap the heat stake elements 68 and, therefore, no heat is applied to those elements.
- the thermal adhesive When heat is applied to the heat stake elements 64, the thermal adhesive is activated and the sealing member 30 adheres to the top side 18 of the cartridge 10. In addition, the heat stake elements 64 melt and therefore bond to the sealing member 30. More particularly, the elements 64 bond to a substrate of the sealing member 30. Such bonding is depicted in FIG. 6 , in which a heat stake element 64 is shown passing through a thermal adhesive layer 80 and a peeling layer 82 of the sealing member 30 to the substrate 84 of the sealing member.
- a second die 72 is used to apply heat to the same heat stake elements 64 that were heated in the stage depicted in FIG. 5A .
- the die 72 does not overlap the heat stake elements 68 and, therefore, no heat is applied to those elements.
- heat was not applied to the heat stake elements 68 in either of the stages depicted in FIGs. 5A and 5B those elements were not bonded to the sealing member 30 and the thermal adhesive adjacent to those elements was not activated.
- the heat stake elements 68 extend up from the surface 66 of the top side 18, they support the sealing member 30 above that surface, thereby forming air gaps through which air within the cartridge 10 that expands during the first two stages of heat staking can escape.
- FIG. 7 Such a configuration is depicted in FIG. 7 .
- the heat stake element 64 forms air gaps 86 through which air can escape, as indicated by arrows 88.
- a third heat staking die 74 can then be applied to the cartridge 10 that overlaps the three heat stake elements 64 closest to the T-shaped end 62, as well as the heat stake elements 68.
- the sealing member 30 is hermetically sealed to the cartridge 10 and therefore prevents the ingress or egress of air into or out of the cartridge via the vent 50.
- the manufacturing of the cartridge 10 is completed and the cartridge can be provided to an end user for use in a printing device.
- the user will remove the tear-away portion 38 of the sealing member 30 first illustrated in FIG. 2 .
- the user can pull the end portion (pull tab) 32 of the sealing member 30 and peel the member off of the rear side 16 and part of the top side 18 of the cartridge 10 against the bonding force of the pressure sensitive and thermal adhesive.
- the portion of the sealing member 30 that has been removed from the cartridge 10 extends to the tear slits 18, further pulling results in the tear-away portion 46 separating from the remainder of the sealing member, thereby exposing the T-shaped end 62 of the vent channel 56, as illustrated in FIG. 8 . Through such exposure, air can travel through the channel 56 and to the vent opening 54.

Description
- Ink cartridges used in inkjet printers typically comprise a vent that allows air to enter the cartridge as ink is drawn from the cartridge. The passage of such air into the cartridge avoids the creation of a vacuum within the cartridge and, therefore, facilitates the flow of ink from the cartridge.
- The vent of an ink cartridge is normally sealed prior to use to avoid evaporation of the ink contained within the cartridge and leakage from the vent due to pressure changes during shipment. In some cases, the vent is covered by a sealing member that the end user removes prior to installing the cartridge within a printer. Often, such sealing members are held in place with pressure sensitive adhesive. Unfortunately, such adhesive exhibits high rates of failure, particularly when the adhesive is exposed to higher temperatures and/or altitudes. When the adhesive fails, air can then enter the cartridge and dry out the ink that the cartridge contains.

The vent has a vent hole passing through the cover and an elongated vent path that communicatively couples the vent hole to an atmosphere surrounding an exterior of the ink reservoir. A membrane is disposed over the vent hole for acting to repel ink therefrom and for allowing air flow through the membrane and the vent. - The disclosed ink cartridges can be better understood with reference to the following drawings.

Unfortunately, use of pressure sensitive adhesive can be accompanied by high rates of failure, particularly when the adhesive is exposed to higher temperatures and/or altitudes. As described in the following, however, lower rates of failure can be achieved when the sealing member is heat staked to the cartridge. Because the heat staking process can raise the temperature of air contained within the cartridge and therefore can cause that air to expand, heat staking may be performed in a multi-stage process in which the vent is not fully sealed until a final stage of heat staking. In such a case, air may escape from the cartridge during the heat staking process. In some embodiments, heat stake elements used in the heat staking process maintain air gaps between the sealing member and the cartridge that provide pathways for the air to escape.
- Turning now to the figures, in which like numerals identify corresponding parts, illustrated in
FIGs. 1 and 2 is an embodiment of anink cartridge 10 that is configured to contain and supply ink to a printing device, such as a printer. As indicated in those figures, theink cartridge 10 comprises apolymeric body 12 that, for example, is formed through injection molding. Thebody 12 includes afront side 14, arear side 16, atop side 18, abottom side 20, and opposedlateral sides front side 14 is afinger tab 26 that may be used to insert thecartridge 10 into and/or remove the cartridge from a printing device. Extending downward from thebottom side 20 is anink outlet 28 from which ink may be drawn from thecartridge 10. - With further reference to
FIGs. 1 and 2 , shown applied to the surfaces of thetop side 18 and a portion of therear side 16 is asealing member 30 that is used to seal an air vent (not visible inFIGs. 1 and 2 ) provided on the top side of thecartridge 10 that enables air to enter and exit the cartridge. In some embodiments, the sealingmember 30 is printed upon with various indicia, such that the sealing member also functions as a label. Examples of indicia that may be printed upon the sealingmember 30 include indications of the cartridge manufacturer, the cartridge model number, the cartridge manufacturing date, and the like. By way of example, the sealingmember 30 comprises a thin strip of polymeric material. - As described below, the sealing
member 30 is heat staked to thecartridge 10. More particularly, the sealingmember 30 is heat staked to the surface of thetop side 18 at discrete locations. In addition, the sealingmember 30 is adhered to thecartridge 10 with adhesive. In some embodiments, thermal adhesive is provided along the entire length of the sealingmember 30 and pressure sensitive adhesive is provided at discrete locations that do not coincide with an air vent described below. As is further illustrated inFIGs. 1 and 2 , the sealingmember 30 further includestear slits 34 that facilitate intentional tearing of the sealing member at a predetermined point along its length to expose the vent to the ambient air. The portion of the sealingmember 30 that extends from itsend 36 to thetear slits 34 therefore comprises a tear-awayportion 38 of the sealing member that may be removed by the user prior to use of thecartridge 10. By way of example, the tear-away portion 38 is torn away using anend portion 32 of the sealingmember 30 that is not adhered to thecartridge 10 and, therefore, serves as a pull tab. -
FIG. 3 illustrates an example embodiment of anair vent 50 provided on thetop side 18 of thecartridge 10. As shown inFIG. 3 , thevent 50 comprises a labyrinth vent that includes a vent opening 52 provided within acircular recess 54 that is in fluid communication with anelongated vent channel 56. Thechannel 56 comprises a serpentine channel section 58 that extends from therecess 54 to anlinear channel section 60. Thechannel 56 terminates in a T-shaped end 62 that, as described below, is exposed when the tear-away portion 38 of the sealingmember 30 is removed by the end user. - As is further shown in
FIG. 3 , multipleheat stake elements 64 are provided on asurface 66 that defines the upper edges of thecircular recess 54 and thevent channel 56. In the illustrated embodiment, theheat stake elements 64 comprise small cylindrical elements that are unitarily formed with thetop side 18 of thecartridge 10. Although cylindrical elements have been illustrated and described, it is to be understood that theheat stake elements 64 may comprise other shapes, including cones, rounded domes, ribs, and the like. In some embodiments, theheat stake elements 64 are approximately 30 to 500 microns (µm) tall. By way of example, theheat stake elements 64 are approximately 200 µm tall. - The
example cartridge 10 shown inFIG. 3 comprises sevenheat stake elements 64, including a first pair of elements positioned on opposite sides of thecircular recess 54, a second pair of elements positioned on opposite sides of thelinear channel section 60, a lone element positioned within the last curve of the serpentine channel section 58 prior to the linear channel section, and a pair ofelements 68 that are positioned on opposite sides of an intermediate portion of the serpentine channel section. It is noted that greater or fewerheat stake elements 64 can be used/or can be positioned in alternative position as required for the particular cartridge application. As described below, theheat stake elements 68 may be the last elements to be bonded to the sealingmember 30, in which case theelements 68 enable venting of air out from thecartridge 10 during previous stages of the heat staking process. -
FIG. 4 illustrates the sealingmember 30 in place over theair vent 50 prior to heat staking. At that point, the sealingmember 30 is adhered to thetop side 18 and therear side 16 of thecartridge 10 and covers both thecircular recess 54 and thevent channel 60, including the T-shaped end 62. Notably, the sealingmember 30 is not adhered to the cartridge along its entire length. Instead, at least in some embodiments, the portion of the sealingmember 30 that overlies theair vent 50 is not adhered to thecartridge 10 because that portion of the member only comprises thermal adhesive that has not yet been heated. However, other portions of the sealingmember 30, including part of the tear-awayportion 38 and the remainder of the sealing member that overlies the top side 18 (i.e., between theair vent 50 and the front side 14) is adhered to thecartridge 10 due to the presence of the pressure sensitive adhesive that is provided on the underside of the member. Therefore, the pressure sensitive adhesive holds the sealingmember 30 in place until heat staking is performed. - Once the sealing
member 30 has been attached to thecartridge 10, it can be further secured to the cartridge using a heat staking process.FIGs. 5A-5C depict various stages of a multi-stage heat staking process in which multiple heat staking dies are brought into contact with thecartridge 10 and its sealingmember 30. More particularly, illustrated inFIGs. 5A-5C are outlines of the footprints of three different dies to identify theheat stake elements FIG. 5A , afirst die 70 is used to apply heat to the threeheat stake elements 64 closest to the T-shapedend 62 and the two heat stake elementscircular recess 54. Notably, thedie 70 does not overlap theheat stake elements 68 and, therefore, no heat is applied to those elements. When heat is applied to theheat stake elements 64, the thermal adhesive is activated and the sealingmember 30 adheres to thetop side 18 of thecartridge 10. In addition, theheat stake elements 64 melt and therefore bond to the sealingmember 30. More particularly, theelements 64 bond to a substrate of the sealingmember 30. Such bonding is depicted inFIG. 6 , in which aheat stake element 64 is shown passing through athermal adhesive layer 80 and apeeling layer 82 of the sealingmember 30 to thesubstrate 84 of the sealing member. - With reference next to
FIG. 5B , asecond die 72 is used to apply heat to the sameheat stake elements 64 that were heated in the stage depicted inFIG. 5A . Again, thedie 72 does not overlap theheat stake elements 68 and, therefore, no heat is applied to those elements. Because heat was not applied to theheat stake elements 68 in either of the stages depicted inFIGs. 5A and 5B , those elements were not bonded to the sealingmember 30 and the thermal adhesive adjacent to those elements was not activated. Because theheat stake elements 68 extend up from thesurface 66 of thetop side 18, they support the sealingmember 30 above that surface, thereby forming air gaps through which air within thecartridge 10 that expands during the first two stages of heat staking can escape. Such a configuration is depicted inFIG. 7 . As shown in that figure, theheat stake element 64forms air gaps 86 through which air can escape, as indicated byarrows 88. - With reference next to
FIG. 5C , a third heat staking die 74 can then be applied to thecartridge 10 that overlaps the threeheat stake elements 64 closest to the T-shapedend 62, as well as theheat stake elements 68. After that final stage of heat staking, the sealingmember 30 is hermetically sealed to thecartridge 10 and therefore prevents the ingress or egress of air into or out of the cartridge via thevent 50. - At this point, the manufacturing of the
cartridge 10 is completed and the cartridge can be provided to an end user for use in a printing device. To enable such usage, the user will remove the tear-awayportion 38 of the sealingmember 30 first illustrated inFIG. 2 . In particular, the user can pull the end portion (pull tab) 32 of the sealingmember 30 and peel the member off of therear side 16 and part of thetop side 18 of thecartridge 10 against the bonding force of the pressure sensitive and thermal adhesive. Once the portion of the sealingmember 30 that has been removed from thecartridge 10 extends to the tear slits 18, further pulling results in the tear-away portion 46 separating from the remainder of the sealing member, thereby exposing the T-shapedend 62 of thevent channel 56, as illustrated inFIG. 8 . Through such exposure, air can travel through thechannel 56 and to thevent opening 54.
