Printers often utilize removable cartridges, containers or supplies that provide printing material for printing. Some removable supplies include printing elements, such as a print head, to directly print upon the print medium. Other removal supplies include an outlet through which the printing material is supplied to a remote printing element. Many supplies further include a latch which retains the printing material supply in place during use in the printer.

The present disclosure describes a printing material supply that utilizes a latch to removably retain the printing material supply in place with respect to a printer. The latch is pivotally coupled to a body of the supply by living hinge. For purposes of this disclosure, a living hinge comprise a flexure bearing integrally formed as a single unitary body and from the same or similar materials as the two rigid pieces it connects.
Although such living hinges may facilitate a lower cost and less complex printing material supply, such living hinges may be subject to creep, wherein after prolonged flexing of the latch about the living hinge, the latch may not fully resiliently return to its original or intended shape or angle. Many existing ink supplies have latches that experience such creep when packaged and during shipping and/or storage. During shipping and/or storage, the latch may bear against the packaging or vice versa subjecting the latch to prolonged periods of flexing or bending of the latch about the living hinge. The resulting creep may interfere with subsequent use of the latch when retaining the printing material supply in a bay or dock of a printer.
The printing material supply of the present disclosure addresses the issue of creep by including a latch protector as part of the printing material supply. The latch protector serves as a packaging standoff, contacting those surfaces of the packaging that bear against the latch to limit the degree that the latch may flex about its living hinge when bearing against the package.
Body 24 comprises a structure that forms an enclosed volume for containing printing material of a printer. In one implementation, body 24 may be utilized to contain a liquid printing material, such as an ink for printing images or various materials for three-dimensional printing. In one implementation, body 24 may be utilized to contain a solid printing material, such as a powder or other dry forms of printing material.
Dispensing opening 28 constitutes at least one opening or port through which printing material contained within body 24 is dispensed. In one implementation, dispensing opening 28 comprises a port through which the printing material within body 24 is supplied to remote printing elements, wherein the printing element is not carried, supported or provided by supply 20. In another implementation, dispensing opening 28 comprises multiple nozzle openings through which the printing material is selectively ejected to carry out printing. For example, in one implementation, dispensing opening 28 may be provided as part of a print head secured to body 24. Although dispensing opening 28 is illustrated as being located on a bottom face of body 24, in other implementations, dispensing opening 28 may be provided along the sides or top of body 24, depending upon how the printing material is to be dispensed from body 24.
Latch 32 comprises an elongate bar or arm 40 having a catch 42 and being pivotable towards and away from sides of body 24 about a general axis 44 utilizing a living hinge 48. In the example illustrated, arm 40 is integrally formed as part of a single unitary body with at least portions of body 24, forming living hinge 48 that extends between body 24 and the extremities of arm 40. Catch 42 comprise a hook or other projection that interacts with a corresponding catch or hook in a printer or in a bay (also referred to as a dock) of a printer to position and retain supply 20 in place.
Living hinge 48 comprises a flexure bearing formed from a resiliently flexible material and sized or dimensioned so as to allow the outer extremities of arm 40, carrying catch 42, to resiliently flex and pivot between a latched state in which catch 42 interacts with the corresponding catch of the printer receiving bay and an unlatched state. In the example illustrated, living hinge 48 is formed from a polymer such as polypropylene. In other implementations, living hinge 48 may be formed from other polymers or other material including, but not limited to, acrylonitrile butadiene styrene (ABS), polysulfone, polyethylene terephthalate (PET), Nylon, and polyethylene.
In the example illustrated, arm 40 of latch 32 extends from body 24 such that catch 42 is above horizontal axis 44 and above living hinge 48, wherein arm 44 projects upwardly from hinge 48 in a direction away from dispensing opening 28 along the bottom of supply 20. As a result, a user may contact, press and manipulate the outer extremity of arm 40 to pivot the outer extremity of arm 40 towards body 24 and to disengage catch 42 from the corresponding catch of the printer supply bay, allowing supply 20 to be withdrawn from the printer supply bay. In other implementations, arm 40 of latch 32 may alternatively extend at a downward angle, towards the bottom of body 24 and towards dispensing opening 28 on the bottom of body 24, wherein other mechanism provided for facilitating pivoting of arm 40 or otherwise releasing catch 42 when supply 20 is to be removed from the printer supply bay. In yet other implementations, arm 40 of latch 32 may alternatively extend from body 24 sideways or at an angle oblique to the top of body 24, wherein other mechanisms are provided for facilitating the pivoting of arm 40 or otherwise releasing catch 42 when supply 20 is to be removed from the printer supply bay.
Latch protector 36 comprises at least one packaging standoff, such as a bar, arm, post or other projection or protuberance that extends beyond face 25 of body 20 in the same direction that the outer extremities arm 40 are spaced from face 25 of body 20. Latch protector 36 has a rigidity or stiffness greater than that of arm 40 at living hinge 48. Latch protector 36 projects a sufficient distance from face 25 of body 24 so as to limit the extent that arm 40 of latch 32 may pivot or flex towards body 24 when bearing against the sides or other internal surfaces of packaging. Latch protector 36 limits the extent that arm 40 of latch 32 may pivot towards body 24 to a degree such that prolonged exposure to such limited flexing does not result in creep of latch 32.
The degree to which arm 40 of latch 32 may pivot towards body 24 for prolonged periods of time without experiencing creep may vary depending upon the materials, shape and size of those portions of arm 40 forming living hinge 48. In one implementation in which living hinge 48 is formed from polypropylene and has a cross-sectional area of 7.2 mm2, latch protector 36 limits flexing and pivoting of latch 32 about living hinge 48 to an angle of no less than 16 degrees with respect to face 25 of body 24. In one implementation, living hinge 48 allows latch 32 to flex and pivot towards face 25 of body 24 no greater than 11 degrees, until latch protector 36 inhibits any further flexing and pivoting towards face 25 of body 24. In one implementation, living hinge 48 allows latch 32 to flex and pivot towards face 25 of body 24 by no greater than 5 mm towards face 25 of body 24 (as measured in a direction perpendicular to face 25) until latch protector 36 inhibits any further flexing or pivoting towards face 25 of body 24. In other implementations, latch protector 36 may limit such flexing and pivoting of arm 40 about living hinge 48 to other extents depending upon the properties of living hinge 48.
Latch protector 36 is located and sized so as to not interfere with the pivoting of latch 32 when inserted into printer bay 60 and so as to not interfere with the interaction between catch 42 and catch 62. In the example illustrated in
In the example illustrated, projections 154 are located above the upper outer extremity of arm 40. Because projections 154 are spaced on opposite sides of arm 40, a user is still provided access to arm 42 manually pinch or squeeze arm 40 to disengage catch 42 from catch 62 to withdraw supply 20 from supply bay 60 (shown in
Because projection 254 extends through opening 243 in arm 40, projection 254 is more centrally located with respect to arm 40, along a centerline of arm 40. As a result, projection 254 may more reliably engage those surfaces of a package that might otherwise bear against arm 40. Because projection 254 extends through opening 243 in arm 40, projection 254 is less likely to interfere with manual grasping and pinching of arm 40 by user to disengage catch is 42 and 62 for the withdrawal of supply 20 from base 60 (shown in
Although latch protector 236 is illustrated as comprising a single projection 254, in other implementations, latch protector 236 may comprise multiple projections projecting through a single opening or multiple openings extending through arm 40. In some implementations, arm 40 may include notches in the side of arm 40 through each of which a projection 254 extends. In some implementations, latch protector 236 of supply 220 may comprise additional projections or package standoffs such as projections 54 and/or 154 described above. Such additional projections may provide face 25 of body 24 with a large array of multiple projections that extends on all sides of latch 32, more reliably contacting a package surface and more reliably preventing the package surface from unduly flexing arm 40 for prolonged periods of time.
As indicated by block 302, printing material supply 20 is positioned within packaging 310 to position latch 32 into contact with the interior sides or side surfaces 314 of packaging 310 to flex and pivot latch 32 about living hinge 48 towards face 25 of body 24. As indicated by block 306, the flexing and pivoting of latch 32 about living hinge 48 towards face 25 of body 24 of supply 20 is limited by engaging the interior sides 314 of packaging 310 with a latch protector such as latch protector 36 or with another latch protector such as latch protector 136 or 236 described above.
As shown by
Dispensing opening 428 constitutes at least one opening or port through which printing material contained within body 424 is dispensed. In the example illustrated, dispensing opening 428 comprises a port through which the printing material within body 424 is supplied to remote printing elements, printing element is not carried, supported are provided by supply 420. In another implementation, dispensing opening 428 comprises multiple nozzle openings through which the printing material is selectively ejected to carry out printing. For example, in one implementation, dispensing opening 428 may be provided as part of a print head secured to body 424. Although dispensing opening 428 is illustrated as being located on a bottom face of body 424, in other implementations, dispensing opening 428 may be provided along the sides or top of body 424, depending upon how the printing material is to be dispensed from body 424.
Latch 432 comprises an elongate bar or arm 440 having first and second catches 442 located on opposite sides of an opening, shown as an elongate slot 443, extending through arm 440. Arm 440 is pivotable towards and away from face 425 of body 424 about a general axis 444 utilizing a living hinge 448. In the example illustrated, arm 440 is integrally formed as part of a single unitary body with at least portions of body 424, forming living hinge 448 that extends between body 424 and the extremities 445 of arm 440. Catches 442 extend on opposite sides of opening 443, each of catches 442 comprising a hook or other projection that interacts with a corresponding catch or hook in a printer or in a bay of a printer to position and retain supply 420 in place.
Living hinge 448 comprises a flexure bearing formed from a resiliently flexible material and sized or dimensioned so as to allow the outer extremities of arm 440, carrying catches 442, to resiliently flex and pivot between a latched state in which catch 442 interacts with the corresponding catch of the printer receiving bay and unlatched state. In the example illustrated, living hinge 448 is formed from a polymer such as polypropylene. In other implementations, living hinge 448 may be formed from other polymers or other material including, but not limited to, acrylonitrile butadiene styrene (ABS), polysulfone, polyethylene terephthalate (PET), Nylon, and polyethylene.
In the example illustrated, arm 440 of latch 432 extends from body 424 such that catches 442 are above horizontal axis 444 and above living hinge 448, wherein arm 444 projects upwardly from hinge 448 in a direction away from dispensing opening 428 along the bottom of supply 420. As a result, a user may contact, press and manipulate the outer extremity of arm 440 to pivot the outer extremity of arm 440 towards body 424 and to disengage catch 442 from the corresponding catch of the printer supply bay, allowing supply 420 to be withdrawn from the printer supply bay. Although arm 440 is illustrated as having a completely surrounded and enclosed slot or aperture through which latch projector 436 extends, in other implementations, arm 440 may be split into two side-by-side arm portions separated with an elongate channel, wherein latch protector 436 is located within the elongate channel between the two separate and independent arm portions.
In other implementations, arm 440 of latch 432 may alternatively extend at a downward angle, towards the bottom of body 424 and towards dispensing opening 428 on the bottom of body 424, wherein other mechanism provided for facilitating pivoting of arm 440 or otherwise releasing catch 442 when supply 420 is to be removed from the printer supply bay. In yet other implementations, arm 440 of latch 432 may alternatively extend from body 424 sideways or at an angle oblique to the top of body 424, wherein other mechanisms are provided for facilitating the pivoting of arm 440 or otherwise releasing catch 442 when supply 420 is to be removed from the printer supply bay.
Latch protector 436 comprises at least one packaging standoff, such as a bar, arm, post or other projection or protuberance that extends beyond face 425 of body 424 in the same direction that the outer extremities arm 440 are spaced from face 425 of body 424. Latch protector 436 has a rigidity or stiffness greater than that of arm 440 at living hinge 448. Latch protector 436 projects a sufficient distance from face 425 of body 424 so as to limit the extent that arm 440 of latch 432 may pivot or flex towards body 424 when bearing against the sides or other internal surfaces of packaging. Latch protector 436 limits the extent that arm 440 of latch 432 may pivot towards body 424 to a degree such that prolonged exposure to such limited flexing does not result in creep of latch 432.
The degree to which arm 440 of latch 432 may pivot towards body 424 for prolonged periods of time without experiencing creep may vary depending upon the materials, shape and size of those portions of arm 440 forming living hinge 448. In one implementation in which living hinge 448 is formed from polypropylene and has a cross-sectional area of 7.2 mm2, latch protector 436 limits flexing and pivoting of latch 432 about living hinge 448 to an angle of no less than 16 degrees with respect to face 425 of body 424. In other implementations, latch protector 46 may limit such flexing and pivoting of arm 440 about living hinge 448 to other extents depending upon the properties of living hinge 448.
Latch protector 436 is located and sized so as to not interfere with the pivoting of latch 432 when inserted into a printer bay and so as to not interfere with the interaction between catch 442 and the catch of the printer bay corresponding to catch 442. In the example illustrated, latch protector 436 comprises a triangular projection integrally formed as part of a single unitary body with face 425 of body 424 and aligned with slot 443 so as to be passable through slot 443 when arm 440 is flexed and pivoted towards face 425 of body 424. The triangular shape of latch projector 436 provides latch projector 436 which additional strength and rigidity, inhibiting latch protector 436 from breaking when experiencing loads when supply 420 is packaged. Latch protector 436 projects upwardly away from face 425 of body 424 so as to contact the interior sides of packaging, but is located so as to not interfere with the flexing of arm 440 during insertion of supply 420 into a package and so as to not interfere with the interaction between catch 442 and the internal catch of the package.
Latch 532 comprises an elongate bar or arm 540 having a catch 542 and being pivotable towards and away from sides of body 424 about a general axis 544 utilizing a living hinge 548. In the example illustrated, arm 540 is integrally formed as part of a single unitary body with at least portions of body 424, forming living hinge 548 that extends between latch protector 536 and the extremities 545 of arm 540. Catch 542 comprise a hook or other projection that interacts with a corresponding catch or hook in a printer or in a bay of a printer to position and retain supply 520 in place.
Living hinge 548 comprises a flexure bearing formed from a resiliently flexible material and sized or dimensioned so as to allow the outer extremities of arm 540, carrying catch 542, to resiliently flex and pivot between a latched state in which catch 542 interacts with the corresponding catch of the printer receiving bay and unlatched state. In the example illustrated, living hinge 548 is formed from a polymer such as propylene. In other implementations, living hinge 48 may be formed from other polymers or other material including, but not limited to, acrylonitrile butadiene styrene (ABS), polysulfone, polyethylene terephthalate (PET), Nylon, and polyethylene.
In the example illustrated, arm 540 of latch 532 hangs from the projection of latch protector 536 such that catch 542 is below the horizontal axis 544 and above living hinge 548, wherein arm 540 hangs downwardly from hinge 548 in a direction away from dispensing opening 28 and towards face 425 such that latch protector 536 projects further away from face 425 than the underlying arm 540 and catch 545.
Latch protector 536 comprises at least one packaging standoff, such as a bar, arm, post or other projection or protuberance that extends beyond 425 of body 424 further away from face 425 than arm 540. In the example illustrated, latch protector 536 horizontally extends from face 45, parallel to the bottom 427 and the top 429 of body 424. In other implementations, the projection or arm of latch protector 536 may extend at other angles from face 425, wherein latch protector 536 extends further outwardly beyond face 425 as compared to the underlying arm 540 of latch 532.
Latch protector 536 has a rigidity or stiffness greater than that of arm 540 at living hinge 548. Latch protector 536 projects a sufficient distance from face 425 of body 424 so as to limit the extent that arm 540 of latch 532 may pivot or flex towards body 424 when bearing against the sides or other internal surfaces of packaging. In the example illustrated, latch protector 536 inhibits packaging from contacting or bearing against latch 532. At the same time, latch protector 536 is located and sized so as to not interfere with the pivoting of latch 532 when inserted into printer bay 560 and so as to not interfere with the interaction between catch 542 and catch 562.
