Detailed Implementation

[0019] The following description uses reference to an example of a liquid container. The liquid container is configured to be installed in a printing apparatus. The liquid container is configured to supply liquid to the printing apparatus by means of its installation in the printing apparatus. The printing apparatus is, for example, an inkjet printer that prints characters, photographs, and other images by ejecting ink, an example of a liquid, onto a medium such as paper or fabric.

[0020] Printing apparatus

[0021] First, the printing apparatus will be explained.

[0022] like Figure 1As shown, the printing apparatus 11 includes a printing unit 12. The printing unit 12 is configured to print an image on a medium 99. The printing unit 12 prints the image on the medium 99 by spraying liquid onto the medium 99.

[0023] The printing section 12 has a head 13. The head 13 is configured to eject liquid. The head 13 has a nozzle surface 15 with one or more nozzles 14 opening. The nozzle surface 15 faces the medium 99. The head 13 ejects liquid from the nozzles 14.

[0024] The printing unit 12 may also have a carriage 16. The carriage 16 carries the head 13. The carriage 16 is configured to scan the medium 99. As a result, the head 13 sprays liquid across the width of the medium 99. In this case, the head 13 is a linear head that scans the medium 99. The head 13 may also be a line head capable of spraying liquid across the full width of the medium 99.

[0025] The printing apparatus 11 includes a supply channel 17. The supply channel 17 is configured to supply liquid flow. The supply channel 17 is connected to the printing unit 12. The supply channel 17 is a flow path for supplying liquid to the printing unit 12.

[0026] The printing apparatus 11 includes a mounting section 18. The mounting section 18 is configured to mount a liquid container 21. The mounting section 18 is connected to a supply channel 17. By mounting the liquid container 21 to the mounting section 18, liquid is supplied from the liquid container 21 to the printing section 12 through the supply channel 17. The mounting section 18 has a supply needle 19. The supply needle 19 is inserted into the liquid container 21. Specifically, the liquid container 21 is mounted to the mounting section 18, and the supply needle 19 is inserted into the liquid container 21. Thus, liquid is discharged from the liquid container 21.

[0027] Liquid container

[0028] Next, the liquid container 21 will be described.

[0029] like Figure 2 As shown, the liquid container 21 has a container bag 22. The container bag 22 is configured to contain liquid. The container bag 22 is flexible. Therefore, the container bag 22 can expand or contract.

[0030] The container bag 22 is composed of one or more films. The container bag 22 can be formed, for example, by bonding multiple films separately. In one example, the container bag 22 is formed by bonding two films together. The container bag 22 can also be formed by bonding two films between their edges. Alternatively, the container bag 22 can be formed, for example, by heat-sealing two films between their edges. The container bag 22 can also be formed, for example, by welding two films together using ultrasound.

[0031] The storage bag 22 can be a pillow-shaped bag, a close-fitting bag, or a bag with accordion pleats. In one example, the storage bag 22 is a pillow-shaped bag. Therefore, in one example, the storage bag 22 does not have three-dimensional pleats. The storage bag 22 can also have three-dimensional pleats.

[0032] The container bag 22 has multiple sides. The container bag 22 has a surface 23 and a back surface 24. Surface 23 and back surface 24 are surfaces facing opposite directions. Surface 23 and back surface 24 are, for example, the surfaces with relatively larger areas in the container bag 22. In one example, when the liquid container 21 is mounted on the printing apparatus 11, surface 23 and back surface 24 are arranged vertically side-by-side. When the liquid container 21 is mounted on the printing apparatus 11, surface 23 faces upward. When the liquid container 21 is mounted on the printing apparatus 11, back surface 24 faces downward. The container bag 22 may also have a bottom surface, sides, etc., in addition to surface 23 and back surface 24.

[0033] The container bag 22 has a surface portion 25 and a back portion 26. The surface portion 25 and the back portion 26 are located opposite each other. The surface portion 25 is the part that constitutes the surface 23. The back portion 26 is the part that constitutes the back portion 24. The container bag 22 expands by widening the gap between the surface portion 25 and the back portion 26. The container bag 22 contracts by narrowing the gap between the surface portion 25 and the back portion 26.

[0034] The storage bag 22 may also have a bottom portion, a side portion, etc., in addition to the surface portion 25 and the back portion 26. The storage bag 22 may also have a three-dimensional pleated portion that forms a three-dimensional pleat. In this case, the three-dimensional pleated portion forms the bottom, side, etc., of the storage bag 22.

[0035] The surface portion 25 and the back portion 26 can each be constructed from a single film. Alternatively, the receiving bag 22 can be constructed by bonding the film constituting the surface portion 25 and the film constituting the back portion 26 together. The surface portion 25 and the back portion 26 can also be constructed from multiple films. The surface portion 25 and the back portion 26 can also be bonded together via films constituting the three-dimensional pleats. The surface portion 25 and the back portion 26 are not limited to being bonded together; they can also be continuous.

[0036] When viewed from above, the container 22 is rectangular. Viewing the container 22 from above means viewing it from a direction perpendicular to the surface 23 or the back surface 24. In one example, when viewed from above, both the surface portion 25 and the back surface portion 26 of the container 22 are rectangular.

[0037] The receiving bag 22 has a peripheral portion 27. The peripheral portion 27 is the portion that forms the edge of the receiving bag 22. The peripheral portion 27 includes the edge of the surface portion 25. The peripheral portion 27 includes the edge of the back portion 26. The peripheral portion 27 is the portion that is connected to each other in the surface portion 25 and the back portion 26. In one example, since the surface portion 25 and the back portion 26 are directly connected, the peripheral portion 27 is the portion that is bonded to each other between the edges of the surface portion 25 and the back portion 26. When the surface portion 25 and the back portion 26 are connected via a three-dimensional pleated portion, the peripheral portion 27 includes a three-dimensional pleated portion.

[0038] The peripheral portion 27 may also include a front end portion 28 and a base end portion 29. When the liquid container 21 is mounted on the printing apparatus 11, the front end portion 28 is the portion of the peripheral portion 27 closest to the mounting portion 18. The base end portion 29 is the portion of the peripheral portion 27 located opposite to the front end portion 28. When the liquid container 21 is mounted on the printing apparatus 11, the base end portion 29 is the portion of the peripheral portion 27 whose distance relative to the mounting portion 18 is greater than the distance between the mounting portion 18 and the front end portion 28.

[0039] The peripheral portion 27 may also include a first end portion 30 and a second end portion 31. The first end portion 30 and the second end portion 31 are portions of the peripheral portion 27 that are connected to the front end portion 28 and the base end portion 29. The first end portion 30 and the second end portion 31 are portions of the peripheral portion 27 that are located in opposite positions to each other.

[0040] The liquid container 21 includes a discharge section 32. The discharge section 32 is configured to discharge liquid from the container bag 22. The discharge section 32 is fitted into the container bag 22. The discharge section 32 is fitted into the peripheral portion 27. More specifically, the discharge section 32 is fitted into the front end portion 28. The discharge section 32 communicates with the interior of the container bag 22. Liquid is discharged from the container bag 22 through the discharge section 32.

[0041] The outlet section 32 is configured to be installed on the mounting section 18. The outlet section 32 is configured to be inserted into the supply needle 19. The liquid container 21 is installed on the printing device 11 by inserting the supply needle 19 into the outlet section 32.

[0042] The outlet 32 ​​is configured to discharge liquid from the receiving bag 22 via the peripheral portion 27. More specifically, the outlet 32 ​​is configured to discharge liquid from the receiving bag 22 via the front end portion 28. The outlet 32 ​​communicates with the inside and outside of the receiving bag 22 via the front end portion 28.

[0043] The outlet section 32 may also have an outer component 33. The outer component 33 is a component that forms an outer casing in the outlet section 32. The outer component 33 is fitted to the front end section 28. The insertion hole 34 opens into the outer component 33. The outlet section 32 is mounted to the mounting section 18 by inserting the supply pin 19 into the insertion hole 34.

[0044] The outlet section 32 may also have a handle component 35. The handle component 35 is fitted to the outer component 33. The handle component 35 is fitted, for example, to rotate relative to the outer component 33. The handle component 35 allows the user to easily move the liquid container 21. The handle component 35 allows the user to easily install the liquid container 21 onto the mounting section 18.

[0045] The outlet section 32 may also include a circuit board 36. The circuit board 36 is mounted on the outer component 33. The circuit board 36 stores information such as the type and remaining amount of liquid contained in the liquid container 21. The circuit board 36 is electrically connected to the mounting section 18 when the supply pin 19 is inserted into the insertion hole 34. Thus, the printing device 11 is electrically connected to the liquid container 21. The printing device 11 may also write the amount of liquid consumed into the circuit board 36.

[0046] like Figure 3 As shown, the output section 32 has a connecting member 37. The connecting member 37 is a member that connects to the printing device 11. The connecting member 37 is a member that connects to the mounting section 18. The connecting member 37 is a member for inserting the supply needle 19.

[0047] Connecting member 37 is fitted to receiving bag 22. Connecting member 37 is fitted to peripheral portion 27. Connecting member 37 is fitted to front end portion 28. Connecting member 37 is located in a position sandwiched between surface portion 25 and back portion 26. Specifically, connecting member 37 is located in a position sandwiched between the edge of surface portion 25 and the edge of back portion 26. Connecting member 37 is, for example, bonded to surface portion 25 and back portion 26. In one example, connecting member 37 is heat-fused relative to surface portion 25 and back portion 26.

[0048] The connecting member 37 is covered by the outer component 33. Specifically, the connecting member 37 is covered by the outer component 3 so as to protrude from the insertion hole 34. The supply needle 19 is inserted into the connecting member 37 through the insertion hole 34. The connecting member 37 has an insertion tube 38. The insertion tube 38 is a tube into which the supply needle 19 is inserted. As the supply needle 19 is inserted into the insertion hole 34, the supply needle 19 is inserted into the insertion tube 38. Through the insertion of the supply needle 19 into the insertion tube 38, liquid is discharged from the receiving bag 22.

[0049] The outlet section 32 has an outlet member 39. The outlet member 39 is a member that allows liquid to be discharged from the receiving bag 22 to the connecting member 37. The outlet member 39 is connected to the connecting member 37. The outlet member 39 extends from the connecting member 37 into the receiving bag 22. The outlet member 39 extends between the surface portion 25 and the back portion 26. That is, the outlet member 39 is located in a position where it is sandwiched between the surface portion 25 and the back portion 26.

[0050] Alternatively, when viewed from above, the outlet component 39 extends from the connecting component 37 to the center of the container 22. In this case, liquid can be easily outleted from the container 22. However, if the liquid container 21 does not have the outlet component 39, liquid in the container 22 near the connecting component 37 will be preferentially outleted. As a result, liquid in the container 22 located far from the connecting component 37 may be difficult to outlet.

[0051] The exiting component 39 extends from the connecting component 37 along the first imaginary axis L1. The exiting component 39 is a long strip of component extending along the first imaginary axis L1. The first imaginary axis L1 is, for example, an imaginary axis passing through the insertion tube 38. In one example, the first imaginary axis L1 is parallel to the first end portion 30 and the second end portion 31.

[0052] The outlet component 39 has one or more connecting tubes 40. In one example, the outlet component 39 has two connecting tubes 40. The connecting tubes 40 are connected to the connecting component 37. The connecting tubes 40 extend from the connecting component 37. The connecting tubes 40 extend from the connecting component 37 along a first imaginary axis L1. The connecting tubes 40 communicate with the insertion tube 38. The connecting tubes 40 form a flow path for liquid flow. The connecting tubes 40 are, for example, flexible hoses. The connecting tubes 40 can also be rigid tubes.

[0053] like Figure 3 as well as Figure 4 As shown, the outlet component 39 has a spacer 41. The spacer 41 is connected to the connecting pipe 40. In one example, the spacer 41 is connected to two connecting pipes 40 respectively. One or more outlet ports 42 open into the spacer 41. In one example, two outlet ports 42 open into the spacer 41. The outlet ports 42 are openings for liquid to flow into the spacer 41. Liquid flows from the spacer 41 into the connecting pipe 40 through the outlet ports 42.

[0054] With the liquid container 21 installed in the mounting part 18, the two outlets 42 are arranged side by side vertically. Therefore, the liquid in the upper part and the liquid in the lower part of the container 22 are discharged through the two outlets 42 respectively. Through the two outlets 42, the liquid that has undergone component sedimentation can be discharged evenly.

[0055] Alternatively, when viewed from above, the spacer 41 is located at the center of the container 22. The spacer 41 is a component that ensures space within the container 22. In one example, the spacer 41 at the center of the container 22 prevents the surface portion 25 and the back portion 26 from sealing together. If the remaining liquid level decreases, the liquid container 21 becomes difficult to drain due to the shrinkage of the container 22. In contrast, by ensuring space within the container 22 through the spacer 41, liquid can be drained smoothly even if the remaining liquid level decreases.

[0056] like Figure 3 As shown, the export component 39 may also have a connecting component 43. The connecting component 43 is connected to the connecting component 37. The connecting component 43 extends from the connecting component 37. The connecting component 43 extends along the first imaginary axis L1. The connecting component 43 is connected to the spacer 41. The connecting component 43 is the component connecting the connecting component 37 and the spacer 41. The connecting component 43 is rigid. The connecting component 43 holds the spacer 41 so that the spacer 41 is located at the center of the receiving bag 22. If the export component 39 does not have a connecting component 43, the connecting tube 40 can be constructed of a rigid tube. In this case, the connecting tube 40 holds the spacer 41 so that the spacer 41 is located at the center of the receiving bag 22.

[0057] like Figure 5 As shown, the liquid container 21 sometimes adopts a different posture than when it is in use, such as during transportation or storage. For example, sometimes the first end portion 30 and the second end portion 31 are positioned side by side vertically. In such cases, the liquid moves within the container bag 22. For example, within the container bag 22, the liquid moves from the top to the bottom. If the liquid moves within the container bag 22, the container bag 22 may sometimes partially expand or contract. For example, sometimes the upper part of the container bag 22 contracts, while the lower part expands. If the container bag 22 contracts, it may put a load on the outlet member 39. If the upper part of the container bag 22 contracts, it may exert a downward force on the outlet member 39 because the container bag 22 adheres to the outlet member 39. For example, sometimes the upper part of the container bag 22 contracts, putting a downward force on the spacer 41. In this case, it may put a load on the connecting member 43 and the connecting member 37.

[0058] First Embodiment

[0059] Next, a first embodiment of the liquid container 21 that reduces the possibility of loading the outlet component 39 will be described.

[0060] like Figure 6 as well as Figure 7As shown, the container bag 22 has one or more sealing portions 50. The container bag 22 may also have multiple sealing portions 50. In one example, the container bag 22 has four sealing portions 50.

[0061] The sealing portion 50 is the portion where the surface portion 25 and the back portion 26 are bonded together. The sealing portion 50 can be a portion that is thermally fused together with the surface portion 25 and the back portion 26, or a portion that is ultrasonically fused together. The sealing portion 50 is distinct from the peripheral portion 27. Therefore, the sealing portion 50 can also be described as the portion where there is no possibility of liquid leakage from the receiving bag 22 after peeling. The sealing portion 50 is located within the receiving bag 22, surrounded by the peripheral portion 27. In one example, the sealing portion 50 is a portion that is dot-bonded within the receiving bag 22.

[0062] The sealing portion 50 reduces the likelihood of loading the outlet component 39. Specifically, the sealing portion 50 reduces the volume of the receiving bag 22. That is, the sealing portion 50 makes it difficult for the receiving bag 22 to expand. Therefore, the receiving bag 22 becomes less likely to expand or contract locally. Consequently, liquid becomes less likely to move within the receiving bag 22. As a result, the likelihood of loading the outlet component 39 is reduced.

[0063] The sealing portion 50 may also be located at a different position than the exiting portion 39 in the direction in which the first imaginary shaft L1 extends. For example, the sealing portion 50 may also be located at a different position than the spacer 41 in the direction in which the first imaginary shaft L1 extends. The sealing portion 50 may also be located between the spacer 41 and the front end portion 28 in the direction in which the first imaginary shaft L1 extends. The sealing portion 50 may also be located between the spacer 41 and the base end portion 29 in the direction in which the first imaginary shaft L1 extends.

[0064] The sealing portion 50 may also be located at a different position from the exiting portion 39 in the direction in which the second imaginary axis L2 extends. The second imaginary axis L2 is an imaginary axis orthogonal to the first imaginary axis L1. The second imaginary axis L2 is, for example, an imaginary axis passing through the spacer 41. In one example, the second imaginary axis L2 is parallel to the front end portion 28 and the base end portion 29. The sealing portion 50 may also be located between the exiting portion 39 and the first end portion 30 in the direction in which the second imaginary axis L2 extends. The sealing portion 50 may also be located between the exiting portion 39 and the second end portion 31 in the direction in which the second imaginary axis L2 extends. The sealing portion 50 may also be located on the second imaginary axis L2.

[0065] When viewed from above, the multiple sealing portions 50 can be positioned symmetrically relative to the outlet member 39. The multiple sealing portions 50 can also be positioned linearly symmetrical about the first imaginary axis L1. That is, the multiple sealing portions 50 can also be positioned side-by-side along the second imaginary axis L2. The multiple sealing portions 50 can also be positioned linearly symmetrical about the second imaginary axis L2. That is, the multiple sealing portions 50 can also be positioned side-by-side along the first imaginary axis L1. The multiple sealing portions 50 can also be positioned point-symmetrical about the spacer 41. Therefore, the container 22 becomes less prone to localized expansion or contraction.

[0066] The receiving bag 22 may also have more than one first sealing portion 51 and more than one second sealing portion 52. In one example, the receiving bag 22 has two first sealing portions 51 and two second sealing portions 52. When viewed from above, the first sealing portions 51 and the second sealing portions 52 are sealing portions 50 located opposite to each other, sandwiching the outlet member 39. In detail, the first sealing portions 51 and the second sealing portions 52 are sealing portions 50 located opposite to each other with reference to a first imaginary axis L1.

[0067] When viewed from above, the first sealing portion 51 is the sealing portion 50 located between the first end portion 30 and the outlet member 39. When viewed from above, the second sealing portion 52 is the sealing portion 50 located between the second end portion 31 and the outlet member 39.

[0068] Alternatively, the first sealing portion 51 may be located in the receiving bag 22 between the outlet member 39 and the first end portion 30. In this case, the first sealing portion 51 can effectively prevent the receiving bag 22 from partially expanding. Alternatively, the second sealing portion 52 may be located in the receiving bag 22 between the outlet member 39 and the second end portion 31. In this case, the second sealing portion 52 can effectively prevent the receiving bag 22 from partially expanding.

[0069] Two first sealing portions 51 are located side-by-side along the first imaginary axis L1. The two first sealing portions 51 are positioned to sandwich the spacer 41 in the direction extending along the first imaginary axis L1. One of the two first sealing portions 51 is located between the spacer 41 and the front end portion 28. The remaining first sealing portion 51 is located between the spacer 41 and the base end portion 29.

[0070] Two second sealing portions 52 are located side-by-side along the first imaginary axis L1. The two second sealing portions 52 are positioned with the spacer 41 sandwiched between them in the direction of extension of the first imaginary axis L1. One of the two second sealing portions 52 is located between the spacer 41 and the front end portion 28. The remaining second sealing portion 52 is located between the spacer 41 and the base end portion 29.

[0071] The first sealing portion 51 and the second sealing portion 52 are located side-by-side along the second imaginary axis L2. The first sealing portion 51 and the second sealing portion 52 are positioned to clamp the exiting member 39 in the direction extending along the second imaginary axis L2. Specifically, the first sealing portion 51 and the second sealing portion 52, located between the spacer 41 and the front end portion 28 in the direction extending along the first imaginary axis L1, are positioned to clamp the exiting member 39 in the direction extending along the second imaginary axis L2. The first sealing portion 51 and the second sealing portion 52, located between the spacer 41 and the base end portion 29 in the direction extending along the first imaginary axis L1, are positioned to clamp the exiting member 39 in the direction extending along the second imaginary axis L2.

[0072] The function and effects of the first embodiment

[0073] Next, the function and effects of the first embodiment will be explained.

[0074] (1-1) The receiving bag 22 has a sealing portion 50 to which the surface portion 25 and the back portion 26 are bonded together, and this sealing portion 50 is different from the peripheral portion 27. According to the above configuration, the volume that the receiving bag 22 can contain can be reduced by the sealing portion 50. Therefore, it becomes difficult for liquid to move within the receiving bag 22. Consequently, the receiving bag 22 becomes less prone to localized shrinkage. Therefore, the possibility of placing a load on the outlet member 39 is reduced.

[0075] Second Embodiment

[0076] Next, a second embodiment of the liquid container 21 will be described. In the second embodiment, the sealing portion 50 differs from that in the first embodiment. The second embodiment can also be combined with the first embodiment.

[0077] like Figure 8 as well as Figure 9As shown, the receiving bag 22 has one or more sealing portions 50. In one example, the receiving bag 22 has two sealing portions 50. The sealing portions 50 may also be located on the second imaginary axis L2. The sealing portions 50 may also be located on the second imaginary axis L2 in a position parallel to the spacer 41. The sealing portions 50 may also be located on the second imaginary axis L2 in a position adjacent to the spacer 41. The sealing portions 50 may also be located in a position to suppress displacement of the outlet member 39. The sealing portions 50 can support the spacer 41 by being adjacent to the spacer 41 on the second imaginary axis L2. For example, the sealing portions 50 can support the spacer 41 from below. As a result, the possibility of loading the outlet member 39 when the upper part of the receiving bag 22 contracts is reduced.

[0078] The receiving bag 22 may also have a first sealing portion 51 and a second sealing portion 52. In one example, the receiving bag 22 has a first sealing portion 51 and a second sealing portion 52. The first sealing portion 51 and the second sealing portion 52 may also be located on the second imaginary axis L2. The first sealing portion 51 and the second sealing portion 52 may also be located on the second imaginary axis L2 in a position parallel to the spacer 41. The first sealing portion 51 and the second sealing portion 52 may also be located on the second imaginary axis L2 in a position that clamps the spacer 41. In one example, the first sealing portion 51, the spacer 41, and the second sealing portion 52 are arranged side by side on the second imaginary axis L2. By positioning the first sealing portion 51 and the second sealing portion 52 on the second imaginary axis L2 to clamp the spacer 41, displacement of the delivery member 39 is suppressed. Thus, the first sealing portion 51 and the second sealing portion 52 can support the spacer 41. As a result, the possibility of loading the output component 39 is reduced.

[0079] The function and effects of the second embodiment

[0080] Next, the function and effects of the second embodiment will be explained.

[0081] (2-1) When viewed from above, the sealing portion 50 is located adjacent to the spacer 41 on the second imaginary axis L2. According to this configuration, the sealing portion 50 can support the outlet member 39. Therefore, the outlet member 39 becomes difficult to displace. As a result, the possibility of loading the outlet member 39 is reduced.

[0082] (2-2) When viewed from above, the first sealing portion 51 and the second sealing portion 52 are positioned on the second imaginary axis L2, clamping the spacer 41. According to this configuration, the first sealing portion 51 and the second sealing portion 52 facilitate support of the outlet member 39. Consequently, the outlet member 39 becomes more difficult to displace.

[0083] Third Embodiment

[0084] Next, a third embodiment of the liquid container 21 will be described. In this third embodiment, the sealing portion 50 differs from both the first and second embodiments. The third embodiment can be combined with the first embodiment, the second embodiment, or both of the first and second embodiments.

[0085] like Figure 10 as well as Figure 11 As shown, the receiving bag 22 has one or more sealing portions 50. In one example, the receiving bag 22 has two sealing portions 50. The sealing portions 50 may also be configured to extend along the first imaginary axis L1. The sealing portions 50 may also be portions bonded together as a strip along the first imaginary axis L1. In this case, compared to the case where the sealing portions 50 are bonded in a point-like manner, the volume of the receiving bag 22 becomes smaller. As a result, the receiving bag 22 becomes difficult to expand or contract locally. Therefore, liquid becomes difficult to move within the receiving bag 22. Consequently, the possibility of loading the outlet component 39 is reduced.

[0086] The sealing portion 50 can also be configured to extend from the front end portion 28 to the base end portion 29. In this case, the sealing portion 50 divides the interior of the container bag 22 into a space for containing liquid and a space for not containing liquid. Therefore, the volume of the container bag 22 becomes smaller. Consequently, it becomes more difficult for liquid to move within the container bag 22.

[0087] The receiving bag 22 may also have a first sealing portion 51 and a second sealing portion 52. In one example, the receiving bag 22 has a first sealing portion 51 and a second sealing portion 52. The first sealing portion 51 and the second sealing portion 52 are positioned to clamp the exit member 39 in the direction extending along the second imaginary axis L2. In one example, the receiving bag 22 has a first sealing portion 51 and a second sealing portion 52. The first sealing portion 51 and the second sealing portion 52 may also be positioned to clamp the spacer 41 in the direction extending along the second imaginary axis L2. When viewed from above, the first sealing portion 51 and the second sealing portion 52 may also pass along the second imaginary axis L2. In one example, the first sealing portion 51, the spacer 41, and the second sealing portion 52 are arranged side by side along the second imaginary axis L2. The first sealing portion 51 and the second sealing portion 52 may also be located adjacent to the spacer 41.

[0088] The first sealing portion 51 and the second sealing portion 52 may also extend along the first imaginary axis L1. The first sealing portion 51 and the second sealing portion 52 may also extend parallel to each other. The first sealing portion 51 may also extend parallel to the first end portion 30. The second sealing portion 52 may also extend parallel to the second end portion 31. The first sealing portion 51 and the second sealing portion 52 may also extend from the front end portion 28 to the base end portion 29.

[0089] The function and effects of the third embodiment

[0090] Next, the function and effects of the third embodiment will be explained.

[0091] (3-1) The sealing portion 50 extends along the first imaginary axis L1. According to the above configuration, since the sealing portion 50 is elongated, liquid becomes difficult to move within the receiving bag 22. This reduces the likelihood of loading the outlet component 39.

[0092] (3-2) The sealing portion 50 extends from the front end portion 28 to the base end portion 29. According to the above configuration, since the volume of the receiving bag 22 is reduced, it becomes more difficult for liquid to move within the receiving bag 22. Therefore, the possibility of placing a load on the outlet component 39 is reduced.

[0093] (3-3) The first sealing portion 51 and the second sealing portion 52 extend along the first imaginary axis L1. According to the above configuration, since the first sealing portion 51 and the second sealing portion 52 are elongated, liquid becomes difficult to move within the receiving bag 22. Therefore, the possibility of loading the outlet component 39 is reduced.

[0094] (3-4) The first sealing portion 51 and the second sealing portion 52 extend from the front end portion 28 to the base end portion 29. According to the above configuration, since the volume of the receiving bag 22 is reduced, liquid is less likely to move within the receiving bag 22. Therefore, the possibility of loading the outlet component 39 is reduced.

[0095] The idea of ​​technology

[0096] The following describes the technical concepts and effects learned based on the above embodiments and modifications.

[0097] (A) A liquid container supplies liquid to a printing apparatus by being installed on the printing apparatus. The liquid container includes: a receiving bag for containing liquid; and a discharge portion fitted to the receiving bag. The discharge portion has: a connecting member for connecting to the printing apparatus; and a discharge component extending from the connecting member into the receiving bag. The receiving bag has: a surface portion and a back portion located at a position where the discharge component is sandwiched; a peripheral portion including the edge of the surface portion and the edge of the back portion; and a sealing portion, which is the portion where the surface portion and the back portion are bonded together, and is a portion distinct from the peripheral portion. According to the above configuration, due to the sealing portion, the volume that the receiving bag can contain is reduced. Therefore, the liquid becomes difficult to move within the receiving bag. Consequently, the receiving bag becomes difficult to shrink locally. Therefore, the possibility of loading the discharge component is reduced.

[0098] (B) In the above-described liquid container, the outlet component may also include: a connecting tube extending from the connecting component along a first imaginary axis; and a spacer connected to the connecting tube, wherein, when viewed from above, the sealing portion is located adjacent to the spacer on a second imaginary axis orthogonal to the first imaginary axis and passing through the spacer. According to this configuration, the sealing portion can support the outlet component. Therefore, the outlet component becomes difficult to displace. As a result, the possibility of loading the outlet component is reduced.

[0099] (C) In the above-described liquid container, the sealing portion may be a first sealing portion, and the container bag may have a second sealing portion where the surface portion and the back portion are bonded together. This second sealing portion is distinct from the peripheral portion. When viewed from above, the first and second sealing portions are positioned on the second imaginary axis, clamping the spacer. With this configuration, supporting the outlet component via the first and second sealing portions becomes easier. Consequently, the outlet component becomes more difficult to displace.

[0100] (D) In ​​the above-described liquid container, the outlet component may also have: a connecting tube extending from the connecting component along a first imaginary axis; and a spacer connected to the connecting tube, with the sealing portion extending along the first imaginary axis. According to this configuration, since the sealing portion is elongated, liquid becomes difficult to move within the container. This reduces the likelihood of overloading the outlet component.

[0101] (E) In the above-described liquid container, the peripheral portion may also have: a front end portion fitted with the outlet portion; and a base end portion opposite to the front end portion, from which the sealing portion extends. According to this configuration, since the volume of the container bag is reduced, it becomes more difficult for the liquid to move within the container bag. Therefore, the possibility of loading the outlet component is reduced.

[0102] (F) In the above-described liquid container, the sealing portion may be a first sealing portion, and the container bag may have a second sealing portion where the surface portion and the back portion are bonded together. This second sealing portion is distinct from the peripheral portion. When viewed from above, the first and second sealing portions are positioned to clamp the outlet component in a direction extending along a second imaginary axis orthogonal to the first imaginary axis, with the second sealing portion extending along the first imaginary axis. According to this configuration, since the second sealing portion is elongated, liquid becomes less likely to move within the container bag. This reduces the possibility of overloading the outlet component.

[0103] (G) In the above-described liquid container, the peripheral portion may also have: a front end portion fitted with the outlet portion; and a base end portion opposite to the front end portion, from which the second sealing portion extends. According to this configuration, since the volume of the container bag is reduced, it becomes more difficult for the liquid to move within the container bag. Therefore, the possibility of loading the outlet component is reduced.
