Description

Technical Field

[0001] This disclosure relates to an ink cartridge. Background Technology

[0002] In some cases, ink cartridges included in liquid dispensing devices (e.g., inkjet printers) are filled with ink using filling bags (ink packs) containing ink.

[0003] Japanese Patent Application Publication No. 2018-2262 discloses a filling bag comprising a receiving bag (bag body) for containing ink, a pouring unit (discharge unit) capable of engaging with the filling port of an ink cartridge provided on a liquid dispensing device, and a cap member capable of being attached to and detached from the pouring unit. According to the filling bag described in Japanese Patent Application Publication No. 2018-2262, a threaded portion is formed in each of the interlocking pouring unit and the cap member, and when the cap member is opened and closed, ink flows downward along the threaded portion to return to the receiving bag. Therefore, this reduces the possibility of contamination of the vicinity of the pouring unit by ink flowing downward along the outer peripheral surface of the cap member when the cap member is opened and closed. Summary of the Invention

[0004] Traditional ink bags have the potential to overflow and leak ink during ink injection, depending on the operation during ink injection. The purpose of this disclosure is to provide an ink bag capable of suppressing ink leakage during ink injection.

[0005] This disclosure relates to an ink cartridge configured to inject ink into an ink cartridge included in a liquid dispensing device, comprising: a bag body configured to contain ink; and a dispensing portion extending from the interior to the exterior of the bag body to dispensing ink, wherein the bag body includes a first grip portion disposed on one of the side portions forming the outer periphery of the bag body, and a second grip portion disposed on a side portion different from the side portion having the first grip portion, wherein the side portion forming the outer periphery includes a first side portion, a second side portion adjacent to the first side portion, and a third side portion adjacent to the second side portion, the dispensing portion being disposed on the first side portion, the first grip portion being disposed on the second side portion, and the second grip portion being disposed on the third side portion.

[0027] The technologies described in this specification have the potential to contribute to the realization of sustainable societies, such as decarbonized / circular societies. In this disclosure, an ink cartridge and a liquid discharge device capable of suppressing ink leakage during ink injection are described as technologies with the potential to contribute to the realization of sustainable societies.

[0028] [First Embodiment]

[0029] <Liquid Discharge Device 100>

[0030] Figure 1 This is a schematic perspective view of the liquid discharge device 100 applicable to this embodiment.

[0031] In this embodiment, the liquid discharge device 100 is described assuming it is an inkjet printer. However, devices applicable to the technology of this disclosure are not limited to inkjet printers, as long as they are configured to discharge droplets.

[0032] In this embodiment, the ink cartridge 200 (see [reference]) contains the ink to be discharged from the discharge head 101. Figure 2 The liquid containers are used as liquid containers. For example, four liquid containers respectively contain cyan, magenta, yellow, and black ink. It should be noted that the liquids that can be contained in the liquid containers of this disclosure are not limited to these four colors of ink. For example, various liquids, including processing fluids, can be used for purposes such as improving the fixing properties of ink on the printing medium 105, reducing gloss unevenness, and improving scratch resistance.

[0033] In this embodiment, the printing medium 105 is assumed to be printing paper and will be described accordingly. However, the media suitable for the technology of this disclosure are not limited to printing paper, as long as they are configured to form an image by applying ink droplets. Examples of printing media 105 other than printing paper include media having various materials and forms, such as films, cloth, optical disc label surfaces, plastic sheets, OHP sheets, and envelopes.

[0034] In this disclosure, "printing" not only means forming meaningful information (e.g., appearing as characters and graphics that are visually perceptible to humans). Additionally, "printing" also means forming meaningless information. Furthermore, in this disclosure, "printing" broadly refers to forming images, designs, patterns, structures, and combinations thereof on the printing medium 105, or processing the medium.

[0035] Figure 1Arrows X, Y, and Z, indicating three directions orthogonal to each other, are shown. Note that, as needed, arrows are also used in other figures referenced in this disclosure. Figure 1 The corresponding arrows X, Y, and Z are shown.

[0036] The Z-direction indicates a direction parallel to the direction of gravity. The +Z-direction is the anti-gravity direction, and the -Z-direction is the direction of gravity. The Z-direction coincides with the vertical (height) direction of the liquid discharge device 100. In the following description, regarding the liquid discharge device 100 and the ink cartridge 200 (see... Figure 2 When "up" or "down" is mentioned, unless otherwise specified, it refers to the vertical direction relative to the direction of arrow Z. Specifically, "up" refers to the +Z direction, and "down" refers to the -Z direction. Additionally, "horizontal direction" refers to the direction orthogonal to the Z direction.

[0037] The Y-direction indicates the transport direction of the printing medium 105 in the liquid discharge device 100, which is a direction orthogonal to the width direction (X-direction) of the liquid discharge device 100 in a plane. The +Y-direction is the direction from the front surface side to the rear surface side of the liquid discharge device 100. The -Y-direction is the direction from the rear surface side to the front surface side of the liquid discharge device 100. The printing medium 105 is transported from the rear surface side to the front surface side of the liquid discharge device 100.

[0038] The X direction indicates a direction parallel to the left-right direction (width direction) of the liquid discharge device 100. The -X direction is the direction from right to left when facing the front surface of the liquid discharge device 100. The +X direction is the direction from left to right when facing the front surface of the liquid discharge device 100. In the following description, when "right" or "left" is mentioned with respect to the liquid discharge device 100 and the ink cartridge 200, unless otherwise stated, it refers to the left-right direction based on the direction of the arrow X. Specifically, "right" indicates the +X direction, and "left" indicates the -X direction.

[0039] like Figure 1 As shown, the liquid discharge device 100 includes a discharge head 101 for discharging ink, a flexible tube 102, and an ink cartridge 103 for storing ink. The ink cartridge 103 includes a storage section 103a for storing ink and an inlet 103b (for injecting ink into the cartridge through the inlet). The liquid discharge device 100 includes a carriage 104 on which the discharge head 101 can be mounted. Note that as a mode for mounting the discharge head 101 on the carriage 104, a configuration that allows for easy attachment and removal, or a configuration that allows for a fixed arrangement, can be used. The liquid discharge device 100 includes a transport roller 106 for transporting printing media 105 in the transport direction (-Y direction) and two guide rails 107 extending along the scanning direction.

[0040] The liquid discharge device 100 repeatedly performs the reciprocating movement of the discharge head 101 (main scan) and the conveying of the printing sheet as the printing medium 105 at predetermined intervals (secondary scan). Synchronously with these actions, various types of printing liquid are selectively discharged from the discharge head 101 and applied to the printing medium 105 to form characters, marks, images, etc.

[0041] In this embodiment, we will assume that cyan, magenta, yellow, and black inks are discharged from the discharge head 101. However, the type of printing liquid discharged from the discharge head 101 is not limited to these four colors of ink.

[0042] The discharge head 101 is mounted on a carriage 104 slidably supported by two guide rails 107 and reciprocates along the guide rails 107 in a straight line by a drive unit (e.g., a motor, not shown). The discharge head 101 includes an energy generating element that generates energy to discharge ink. Examples of energy generating elements include electrothermal conversion elements (heaters), piezoelectric elements, etc.

[0043] Multiple energy generating elements are arranged on the discharge head 101. The discharge energy generating elements allow the ink discharge unit to discharge ink supplied from the ink cartridge 103 via the tube 102. Examples of the ink discharge configuration include generating bubbles in the ink by heating a heater and using these bubbles to generate energy to discharge the ink from the discharge head 101.

[0044] Printing media 105, applied to droplets discharged from the discharge head 101, is conveyed via a transfer roller 106 toward the discharge surface (facing the -Z direction) of the discharge head 101 and in a direction intersecting the movement direction of the carriage 104. The discharge head 101 includes a plurality of nozzle arrays to discharge various types of ink.

[0045] Depending on the type of ink to be discharged from the discharge head 101, ink is pre-discharged from the corresponding ink cartridge 200 containing a predetermined amount of ink (see [reference]). Figure 2 Inject multiple independent ink cartridges 103.

[0046] In this embodiment, the four ink cartridges 103 independently store cyan, magenta, yellow and black ink respectively.

[0047] The ink cartridge 103 and the discharge head 101 are connected to each other via a plurality of tubes 102 corresponding to the types of ink stored in the respective ink cartridges 103. Various types of ink stored in the ink cartridges 103 can be independently supplied to the corresponding nozzle arrays of the discharge head 101 by driving a suction device (e.g., a suction pump not shown) included in the liquid discharge device 100. Of course, during this process, the ink can move in flow channels other than the tubes 102.

[0048] Figure 2 This is a schematic front view of the ink cartridge 200 applicable to this embodiment. Although the arrows X, Y, and Z in the figure are shown with the ink cartridge 200 standing upright on a horizontal plane, the orientation of the ink cartridge 200 not connected to the liquid discharge device 100 can be freely changed.

[0049] like Figure 2 As shown, the ink cartridge 200 includes a bag body 201 for containing ink and a discharge unit 202 extending from the inside of the bag body 201 to discharge ink. In the front view, the bag body 201 includes at least three side portions forming its outer periphery. Note that in the container portion 204 of this disclosure, the area including a side extending in a straight direction and having a width is referred to as a "side portion". One of the side portions is provided with a first grip portion 206, and a side portion different from the side portion provided with the first grip portion 206 is provided with a second grip portion 207.

[0050] Specifically, the ink cartridge 200 includes a flexible bag body 201, a discharge unit 202 (e.g., a nozzle) configured to discharge liquid from the inside of the bag body 201 to the outside, and a cap 203 sealing the discharge unit 202. A flow channel for discharging ink from the inside of the bag body 201 to the outside is formed inside the discharge unit 202. The proximal end of the flow channel is located inside the bag body 201, and the other end of the flow channel is located outside the bag body 201. The cap 203 is detachably attached to the other end of the flow channel. The bag body 201 includes a container portion 204 for containing ink and a non-container portion 205 for not containing ink.

[0051] In this embodiment, the bag body 201 is formed by fixing (e.g., heat-sealing) multiple matching side portions of multiple (e.g., two) films together. That is, the non-container portion 205 in this embodiment is a welded portion where multiple films are fused together. The non-container portion 205 is formed continuously along the outer periphery of the bag body 201.

[0052] In this embodiment, the non-container portion 205 includes a first side portion 205a, which is fixed while clamping the discharge unit 202 and intersects with the direction in which the discharge unit 202 extends (in... Figure 2 In the example, it extends in an orthogonal direction. In the first side portion 205a, the discharge unit 202 is fixed by welding while being clamped between the two membranes. The non-container portion 205 includes a second side portion 205b, which is adjacent to the first side portion 205a and extends in a direction intersecting the first side portion 205a. The second side portion 205b includes a first grip portion 206 configured to allow a user to hold it.

[0053] The first grip portion 206 is formed such that its width (the dimension in the direction from the outer periphery of the bag body 201 toward the container portion 204) is greater than the strip-shaped portion formed in the second side portion 205b. In this embodiment, the first grip portion 206 is formed in a semi-circular shape from the second side portion 205b toward the container portion 204. However, the shape of the first grip portion 206 is not limited to a semi-circle, as long as it is a shape that allows the user to grip it.

[0054] The non-container portion 205 includes a third side portion 205c, which is adjacent to and extends to intersect with the second side portion 205b. The third side portion 205c is the longest in the non-container portion 205 of this embodiment. The third side portion 205c includes a second grip portion 207 configured to allow a user to hold it. The second grip portion 207 is formed such that its width (the dimension in the direction from the outer periphery of the bag body 201 toward the container portion 204) is greater than the strip-shaped portion formed in the third side portion 205c.

[0055] The non-container portion 205 includes a fourth side portion 205d, which is adjacent to and extends to intersect with the third side portion 205c.

[0056] In this embodiment, the second grip portion 207 is formed in a quarter-circle shape from the corner formed by the third side portion 205c and the fourth side portion 205d toward the container portion 204. However, the shape of the second grip portion 207 is not limited to a quarter-circle shape, as long as it is a shape that allows the user to grip it.

[0057] The non-container portion 205 includes a fifth side portion 205e, which extends to connect the fourth side portion 205d and the first side portion 205a to each other.

[0058] Figure 3 This is a diagram illustrating the method of injecting ink from ink cartridge 200 into ink cartridge 103 in this embodiment.

[0059] like Figure 3 As shown, the ink cartridge 200 is configured to inject ink into the ink cartridge 103. The ink cartridge 103 includes a storage section 103a for storing ink and an injection port 103b provided on the upper side (+Z direction side) of the storage section 103a. Ink injected through the injection port 103b is stored in the storage section 103a.

[0060] With ink injected into the ink cartridge 103, the user holds the first grip 206 and the second grip 207 while orienting the ejection unit 202 in the direction of gravity. Note that although both the first grip 206 and the second grip 207 are held in this embodiment, either the first grip 206 or the second grip 207 can be held. Furthermore, by connecting the ink cartridge 200 to the ink cartridge 103 while orienting the ejection unit 202 in the direction of gravity, liquid can be injected from the ink cartridge 200 into the ink cartridge 103.

[0061] With ink injected into ink cartridge 103, the user closes the cap 203 of ink pack 200 (see...). Figure 2 Remove from discharge unit 202.

[0062] The discharge unit 202 is internally equipped with a connection unit (e.g., a slit valve mechanism, a valve spring mechanism, etc.). The valve in the connection unit remains closed until the discharge unit 202 of the ink cartridge 200 engages with the inlet 103b of the ink cartridge 103. Therefore, even when the discharge unit 202 is tilted, ink will not leak from the discharge unit 202 until it engages with the inlet 103b.

[0063] When the discharge unit 202 is engaged with the injection port 103b, the valve located inside the discharge unit 202 opens, and ink is injected from the ink cartridge 200 into the ink box 103 by gravity. In the following description, the posture of the discharge unit 202 facing the direction of gravity (-Z direction) is ( Figure 3 The posture of the ink cartridge 200 shown is called the "injection posture".

[0064] For example, the user removes the cover 203 of the ink cartridge 200, and then rotates the ink cartridge 200 until the discharge unit 202 is facing upwards. Figure 3 The +Z direction of the ink cartridge is set to an injection posture facing the direction of gravity (-Z direction). In this disclosure, for example, when the ink cartridge 200 is rotated clockwise to set the injection posture, the direction at 3 o'clock in the rotation direction ( Figure 3 The +X direction in the diagram is referred to as "front". On the other hand, when the ink cartridge 200 is rotated clockwise to set the injection posture, the direction at 9 o'clock in the rotation direction ( Figure 3 The -X direction in the equation is called "rear".

[0065] In the injection posture, the first gripping part 206 is located in front of and above the discharge unit 202, and the second gripping part 207 is located behind the discharge unit 202 and above the first gripping part 206.

[0066] With this configuration, in the injection posture, the first grip portion 206 and the second grip portion 207 are positioned above the ink discharge unit 202 from which the ink flows out; therefore, the possibility of ink adhering to the user's fingers can be suppressed. Furthermore, in the injection posture, the first grip portion 206 and the second grip portion 207 are positioned in front of and behind the discharge unit 202 in the rotational direction (on the +X and -X directions respectively); therefore, the injection posture can be stably maintained.

[0067] Considering the scenario where a user holds the ink cartridge 200 for transport, the length of each of the first grip portion 206 and the second grip portion 207 along the corresponding side portion forming the outer periphery of the bag body 201 is preferably 10 cm or less.

[0068] In the injection posture, considering that the first gripping portion 206 and the second gripping portion 207 are gripped by the user's fingers, the area of ​​both the first gripping portion 206 and the second gripping portion 207 is preferably 1 cm². 2 above.

[0069] Considering the possibility that ink may adhere to the user's fingers during ink injection, the first grip portion 206 is preferably arranged at a position more than 3 cm away from the discharge unit 202.

[0070] As described above, in this embodiment, operability during ink injection is improved when the user holds the first grip 206 with one hand and the second grip 207 with the other hand.

[0071] Furthermore, since the first grip portion 206 and the second grip portion 207 are held by the user's hands, the container portion 204 is not held during ink injection. Therefore, the possibility of the container portion 204 being accidentally squeezed by the user during ink injection and thus applying pressure to the inside of the container portion 204 (which would cause ink to overflow from the discharge unit 202) can be suppressed.

[0072] Furthermore, in the injection posture of this embodiment, the first gripping part 206 and the second gripping part 207 are located above the dispensing unit 202. Therefore, even if ink overflows from the dispensing unit 202 during ink injection, contamination of the user's fingers can be suppressed.

[0073] Furthermore, in the injection posture of this embodiment, the first gripping part 206 and the second gripping part 207 are respectively arranged in front of and behind the dispensing unit 202, and are held and fixed by the user in such a position. Therefore, the injection posture becomes stable.

[0074] Therefore, the ink cartridge according to this embodiment can suppress ink leakage during ink injection.

[0075] [Second Embodiment]

[0076] In this embodiment, a simpler-shaped ink cartridge is provided. In the following description, the same reference numerals are used for structures similar to or corresponding to those of the first embodiment, and descriptions are omitted; the main differences are described.

[0077] Figure 4 This is a schematic front view of the ink cartridge 200 applicable to this embodiment.

[0078] like Figure 4 As shown, the ink cartridge 200 of this embodiment includes four side portions. Specifically, when viewed from the front, the shape of the cartridge 201 is approximately rectangular. The non-container portion 205 of this embodiment includes a first side portion 205a, a second side portion 205b, a third side portion 205c, and a fourth side portion 205d.

[0079] In this embodiment, the first grip portion 206 is disposed at the corner formed by the first side portion 205a and the second side portion 205b. The shape of the first grip portion 206 in this embodiment is a quarter circle. However, the shape of the first grip portion 206 is not limited to a quarter circle.

[0080] The second grip portion 207 is disposed on the third side portion 205c. In this embodiment, the second grip portion 207 is disposed approximately at the center of the third side portion 205c. The shape of the second grip portion 207 in this embodiment is semi-circular. However, the shape of the second grip portion 207 is not limited to semi-circular.

[0081] With this configuration, in the injection posture, the first gripping part 206 and the second gripping part 207 are also located above the dispensing unit 202; therefore, the possibility of ink adhering to the user's fingers can be suppressed.

[0082] Furthermore, although the second grip 207 is located on the virtual line 401 of the vertically extending discharge unit 202 in the injection posture of this embodiment, the injection posture can still be stably maintained even with this arrangement. In this embodiment, as described above, the operability during ink injection is improved when the user holds the first grip 206 with one hand and the second grip 207 with the other hand to maintain the injection posture.

[0083] Therefore, according to the technology of this embodiment, ink cartridges with simpler shapes can be provided.

[0084] [Third Embodiment]

[0085] In this embodiment, a self-standing ink cartridge is provided. In the following description, the same reference numerals are used for structures similar to or corresponding to those in the first and second embodiments, and descriptions are omitted; the main differences are described.

[0086] Figure 5 This is a schematic perspective view of the ink cartridge 200 applicable to this embodiment, viewed from the front and top.

[0087] like Figure 5 As shown, the ink cartridge 200 of this embodiment includes a support plate portion 500 located at the bottom of the container portion 204 in the upright state. This replaces the fourth side portion 205d (see...). Figure 2 In this embodiment, the non-container portion 205 includes a front weld portion 501a between the support portion 500 and the film on the front surface side, and a rear weld portion 501b between the support portion 500 and the film on the rear surface side. In this embodiment, the first grip portion 206 and the second grip portion 207 are semi-circular in shape. However, the shapes of the first grip portion 206 and the second grip portion 207 are not limited to semi-circular.

[0088] This design allows the ink cartridge 200 to stand upright, which is very convenient. Furthermore, the support plate allows the internal volume of the container section 204 to be larger than the internal volume of the first and second embodiments.

[0089] With this configuration, in the injection posture, the first gripping part 206 and the second gripping part 207 are also located above the discharge unit 202. In addition, the second gripping part 207 is located behind the discharge unit 202, and the first gripping part 206 is located in front of the discharge unit 202.

[0090] Therefore, according to the technology of this embodiment, a self-standing ink cartridge can be provided. Furthermore, the capacity can be increased.

[0091] [Fourth Embodiment]

[0092] In this embodiment, an ink cartridge that allows for easy identification of the injection posture is provided. In the following description, the same reference numerals are used for structures similar to or corresponding to those in the first to third embodiments, and descriptions are omitted therein; the differences are mainly described.

[0093] Figure 6 This is a schematic front view of the ink cartridge 200 applicable to this embodiment.

[0094] like Figure 6 As shown, when viewing the ink cartridge 200 of this embodiment from the front, the container portion 204 includes an arrow 600 indicating the rotation direction for setting the ink cartridge 200 to the injection posture.

[0095] Although the direction of arrow 600 is clockwise in this embodiment, the rotation direction of ink cartridge 200 can be counterclockwise, as long as the ink cartridge 200 can be set to the injection posture during ink injection. That is, the direction of arrow 600 can be set as needed according to the positional relationship between the first gripping part 206, the second gripping part 207 and the dispensing unit 202.

[0096] Furthermore, although the arrow is displayed approximately at the center of the container portion 204 in this embodiment, the display position of the arrow is not limited to the approximate center of the container portion 204, as long as the ink cartridge 200 can be set to the injection posture during ink injection. The arrow 600 can be printed directly on the front surface of the container portion 204, the raised portion indicating the arrow 600 can be formed on the surface of the container portion 204, or a label printed with the arrow 600 can be affixed to the front surface of the container portion 204. Of course, multiple arrows 600 can be displayed.

[0097] Additionally, the guidance applied to the ink cartridge 200 can be any guidance other than arrows, as long as it guides the user to position the ink cartridge 200 in the injection posture. For example, text instructing the user to rotate the ink cartridge 200 so that the ejection unit 202 faces the weight direction can be displayed.

[0098] <Ink Injection Method>

[0099] Figures 7A to 7C This is a diagram illustrating the ink injection process applicable to this embodiment.

[0100] Figure 7A This shows the removal of the cap 203 from the unused ink cartridge 200 (see [link]). Figure 6 A diagram of states (e.g., ...). Figure 7A As shown, first, the user removes the cover 203 from the discharge unit 202. After removing the cover 203 from the discharge unit 202, the user holds the first grip 206 and the second grip 207.

[0101] Figure 7B This diagram illustrates the state in which the user holds the first grip portion 206 and the second grip portion 207. (See diagram below.) Figure 7B As shown, the user holds the first grip 206 and the second grip 207 and lifts the ink cartridge 200. Additionally, the user rotates the ink cartridge 200 while holding the first grip 206 and the second grip 207.

[0102] Figure 7C This diagram shows the ink cartridge 200 in the injection posture. (Example) Figure 7CAs shown, the user rotates the ink cartridge 200 in the direction of rotation indicated by arrow 600 and sets it to the injection position. Therefore, while maintaining the injection position, the user engages the injection port 103b with the discharge unit 202. Once the discharge unit 202 is engaged with the injection port 103b, the valve of the valve mechanism is opened, and ink is injected.

[0103] With this configuration, the rotation direction in which the ink cartridge 200 is set to the injection posture can be more easily identified compared to a configuration that does not display the rotation direction.

[0104] Therefore, the ink cartridge according to this embodiment allows for easy identification of the injection posture. Specifically, the two grips and the ejection unit are positioned... Figure 6 In the positional relationship shown, when the ink cartridge 200 is rotated to the injection position, the first grip 206 and the second grip 207 can be held behind the discharge unit 202 in the rotational direction, as shown in FIG7. Therefore, even if ink drips from the discharge unit 202 for some reason, the possibility of ink contaminating the user's fingers can be suppressed. However, in this embodiment, the positions of the two grips and the discharge unit are not limited to the example described above.

[0105] [Fourth variant embodiment]

[0106] Figure 8 This is a diagram illustrating a variant of the ink cartridge 200 applicable to the fourth embodiment. (See diagram for example.) Figure 8 As shown, in this variant, the first grip portion 206 is provided on the fifth side portion 205e. Other configurations are similar. Figure 6 and Figures 7A to 7C The example shown.

[0107] Figures 9A to 9C This is a diagram illustrating the ink injection process in this variant example.

[0108] Figure 9A This diagram shows the state of the unused ink cartridge 200 with its cap 203 removed. (See diagram.) Figure 9A As shown, first, the user will cover 203 (see...) Figure 8 Remove from discharge unit 202.

[0109] Figure 9B This diagram shows the state in which the user rotates the ink cartridge 200 while holding the first grip part 206 and the second grip part 207.

[0110] Figure 9C This diagram shows the ink cartridge 200 in the injection posture.

[0111] In this variant example, such as Figure 9BAs shown, once the user holds the first grip 206 and rotates the ink cartridge 200 in the rotation direction indicated by arrow 600, the fingers holding the first grip 206 are positioned directly below the ejection unit 202. Therefore, with Figure 6 Compared to other designs, this one is more likely to contaminate the user's fingers. However, even with this design, the application of Arrow 600 allows the user to attach the ink cartridge to the ink cartridge and fill the cartridge with ink in the correct rotation direction.

[0112] In other words, in this variant, it is also possible to suppress ink leakage during ink injection while appropriately filling the ink cartridge with ink.

[0113] [Fifth Embodiment]

[0114] In this embodiment, an ink cartridge that is easier to hold is provided. In the following description, the same reference numerals are used for structures similar to or corresponding to those in the first to fourth embodiments, and descriptions are omitted therein; the main differences are described.

[0115] Figure 10 This is a schematic front view of the ink cartridge 200 applicable to this embodiment.

[0116] like Figure 10 As shown, in this embodiment, in addition to the first side portion 205a, the side portion also has a third grip portion 1001, which is different from the first grip portion 206 and the second grip portion 207. For example, the third side portion 205c has the second grip portion 207 and the third grip portion 1001. The third grip portion 1001 is configured to be gripped by a user. The third grip portion 1001 is formed such that its width (the dimension in the direction from the outer periphery of the bag body 201 toward the container portion 204) is larger than the strip-shaped portion formed in the third side portion 205c.

[0117] The third grip portion 1001 is formed in a semi-circular shape from the third side portion 205c toward the container portion 204. However, the shape of the third grip portion 1001 is not limited to a semi-circle; it can be any shape that allows the user to grip it. Considering the possibility of the user gripping it with their fingers, the third grip portion 1001 preferably has a diameter of 1 cm. 2 The above area.

[0118] The second grip portion 207 is provided on the corner formed by the third side portion 205c and the fourth side portion 205d. The third grip portion 1001 is provided between the corner formed by the second side portion 205b and the third side portion 205c and the second grip portion 207.

[0119] In this embodiment, during ink injection from the ink cartridge 200 into the ink container 103, the user holds the second grip 207 and any one of the first grip 206 and the third grip 1001. Therefore, in the injection posture, the first grip 206, the second grip 207, and the third grip 1001 are positioned above the dispensing unit 202. Thus, even when the user is injecting ink while holding both the second grip 207 and the third grip 1001, the possibility of the user's fingers being contaminated with ink can be reduced.

[0120] Furthermore, in the injection posture of this embodiment, the first gripping part 206 and the third gripping part 1001 are located in front of the discharge unit 202, and the second gripping part 207 is located behind the discharge unit 202. Therefore, operability can be improved and the injection posture can be stabilized.

[0121] As described above, compared to the ink cartridges of the first to fourth embodiments, the ink cartridge according to this embodiment can provide more gripping portions during ink injection. Therefore, during ink injection, it is convenient to select any one of the second gripping portion 207, the first gripping portion 206, and the third gripping portion 1001 for gripping.

[0122] Therefore, according to the technology of this embodiment, an ink cartridge that is easier to hold can be provided.

[0123] [Sixth Embodiment]

[0124] In this embodiment, an ink cartridge with a grip portion provided on the outer side of the side portion is provided. In the following description, the same reference numerals are used for structures similar to or corresponding to those in the first to sixth embodiments, and descriptions are omitted therein; the differences are mainly described.

[0125] Figure 11 This is a schematic front view of the ink cartridge 200 applicable to this embodiment.

[0126] like Figure 11 As shown, in this embodiment, the first grip portion 206 is configured to protrude from the second side portion 205b in a direction away from the container portion 204. In this embodiment, the first grip portion 206 is located approximately at the center of the second side portion 205b. The second grip portion 207 is configured to protrude from the third side portion 205c in a direction away from the container portion 204. In this embodiment, the second grip portion 207 is located at the corner formed by the third side portion 205c and the fourth side portion 205d.

[0127] In this embodiment, the first grip portion 206 and the second grip portion 207 are shaped as semi-circular protrusions extending from the inside to the outside of the bag body 201. However, the shapes of the first grip portion 206 and the second grip portion 207 are not limited to semi-circular protrusions.

[0128] With this configuration, the first grip portion 206 and the second grip portion 207 do not extend from the second side portion 205b and the third side portion 205c toward the container portion 204, respectively. Therefore, in this embodiment, the capacity of the container portion 204 can be greater than that in the above embodiments.

[0129] Therefore, according to the technology of this embodiment, an ink cartridge with a grip portion provided on the outer side of the side portion can be provided. Furthermore, the ink capacity that can be contained is greater than that in the first, second, fourth, and fifth embodiments.

[0130] [Seventh Embodiment]

[0131] In this embodiment, an ink cartridge capable of holding more ink is provided compared to the embodiments described above. In the following description, the same reference numerals are used for structures similar to or corresponding to those in the first to sixth embodiments, and descriptions are omitted; the main differences are described.

[0132] Figure 12 This is a schematic perspective view of the ink cartridge 200 applicable to this embodiment, viewed from the front and top.

[0133] like Figure 12 As shown, the ink cartridge 200 of this embodiment includes a support plate portion 500. Therefore, compared with a structure that does not include the support plate portion 500, the posture other than the injection posture can be more stable, and the capacity can also be larger.

[0134] In this embodiment, the first grip portion 206 is configured to protrude from the second side portion 205b in a direction away from the container portion 204. In this embodiment, the first grip portion 206 is located approximately at the center of the second side portion 205b.

[0135] The second gripping part 207 is configured to protrude from the front welded part 501a in a direction away from the container part 204. The second gripping part 207 is located near the corner formed by the front welded part 501a and the third side part 205c.

[0136] In this embodiment, the first gripping portion 206 and the second gripping portion 207 are semi-circular protrusions. However, the shapes of the first gripping portion 206 and the second gripping portion 207 are not limited to semi-circular protrusions.

[0137] With this configuration, similar to the third embodiment, the support portion 500 can accommodate a larger capacity of ink than the configuration without the support portion 500. Furthermore, similar to the seventh embodiment, since the first grip portion 206 and the second grip portion 207 do not extend from the second side portion 205b and the third side portion 205c toward the container portion 204 respectively, the capacity of the container portion 204 is not reduced.

[0138] Therefore, the ink cartridge according to this embodiment can hold more ink.

[0139] [Eighth Embodiment]

[0140] In this embodiment, an ink cartridge that can further improve grip is provided. In the following description, the same reference numerals are used for structures similar to or corresponding to those in the first to seventh embodiments, and descriptions are omitted therein; the main differences are described.

[0141] Figure 13 This is a schematic front view of the ink cartridge 200 applicable to this embodiment.

[0142] like Figure 13 As shown, the first grip portion 206 in this embodiment includes an anti-slip portion 1300, on which an anti-slip processing is performed to make the frictional force greater than the frictional force on the front surface of the container portion 204. It should be noted that an anti-slip processing can be performed on the second grip portion 207, or on both the first grip portion 206 and the second grip portion 207.

[0143] Examples of the anti-slip portion 1300 include components such as paper, film, and rubber fixed to the first grip portion 206. The components fixed to the first grip portion 206 are not limited to paper, film, rubber, etc., as long as they have a frictional force greater than that on the front surface of the container portion 204. These components are attached to the first grip portion 206 by welding, adhesive, etc. That is, each of the first grip portion 206 and the second grip portion 207 can be formed such that the thickness (in...) Figure 13 The length extending in the depth direction is greater than the thickness of the strip-shaped portion formed in each of the second side portion 205b and the third side portion 205c.

[0144] This structure can further improve the gripping force compared to a structure that directly grips the flat and smooth membrane forming the non-container portion 205 and the container portion 204.

[0145] As the anti-slip part 1300, the front surface of the first gripping part 206 can be machined (e.g., rough surface machining) to form a rough surface with a frictional force greater than that on the front surface of the container part 204.

[0146] This design allows for greater friction when gripping the first grip portion 206 compared to a design excluding the anti-slip portion. Therefore, the ink cartridge of this embodiment further enhances grip strength.

[0147] <Method for forming anti-slip part 1300>

[0148] Figure 14A and Figure 14B This is a diagram illustrating a method for forming the anti-slip portion 1300 applicable to this embodiment. In the following description, it is assumed that rubber is welded onto the first grip portion 206 to serve as the anti-slip portion 1300.

[0149] Figure 14A This diagram illustrates the steps involved in performing a smoothing process on the first gripping part 206.

[0150] Figure 14A The ink cartridge before the formation of the anti-slip portion 1300 is shown. A smoothing process is performed on the predetermined portion 1400 on which the anti-slip processing is to be performed. In some cases, the predetermined portion 1400 has unevenness or is contaminated. Under such conditions, it is difficult to obtain excellent weld performance when performing welding. Therefore, in this embodiment, a smoothing process is performed on the predetermined portion 1400, thereby enabling a more secure weld to the rubber used as the anti-slip portion 1300. Thus, compared to welding the rubber to the predetermined portion 1400 without performing a smoothing process, the rubber can be welded to the predetermined portion 1400 more securely.

[0151] Figure 14B This is a diagram showing the steps of forming the anti-slip portion 1300 on the first grip portion 206.

[0152] like Figure 14B As shown, the rubber used as the anti-slip part 1300 is welded to the predetermined part 1400 that has been applied (see...). Figure 14A On the part of ), the rubber can be fused to a smoother front surface using this method.

[0153] Therefore, according to the method for forming the anti-slip portion in this embodiment, the anti-slip portion can be formed more firmly in the first grip portion.

[0154] [Eighth variant embodiment]

[0155] Figure 15 This is a schematic front view of the ink cartridge 200 applicable to this variant.

[0156] like Figure 15 As shown, the first gripping part 206 in this variant includes Figure 15One or more through holes penetrate the first grip portion 206 in the depth direction. With this configuration, once the user grips the first grip portion 206, the user's fingers (e.g., the first finger) and fingers (e.g., the second finger) directly contact each other through the through holes. Therefore, this configuration also improves grip strength. Note that the through holes can be formed in the second grip portion 207, or in both the first grip portion 206 and the second grip portion 207.

[0157] [Other Embodiments]

[0158] Although two or three gripping parts are formed in the above embodiments, four or more gripping parts may also be formed.

[0159] The liquid ejection devices to which the technology of this disclosure is applicable are not limited to serial scanning inkjet printers. For example, the technology of this disclosure can also be applied to so-called full-line inkjet printers, which have a length in a width direction orthogonal to the transport direction and apply ink droplets to the printing medium without scanning.

[0160] According to the ink cartridge disclosed herein, ink leakage can be suppressed during ink injection.

[0161] While this disclosure has been described with reference to exemplary embodiments, it should be understood that this disclosure is not limited to the disclosed exemplary embodiments. The scope of the appended claims should be accorded the broadest interpretation so as to cover all such variations and equivalent structures and functions.
