  The filter chamber 71 is partitioned by the filter 72 into an upstream space 71u located on the upstream side of the filter 72 and a downstream space 71d located on the downstream side of the filter 72 (FIG. 15). The upstream space 71u is connected to the storage chamber 31 via the first communication port 76a and the second communication port 76b. The downstream space 71d is a space surrounded by the filter support wall 75, and is connected to the outlet channel 78 (FIGS. 15 and 16). The upstream space 71u is located below the filter 72 and the downstream space 71d.

  The first communication port 76a and the second communication port 76b communicating with the upstream space 71u are opened in the bottom surface 31b of the storage chamber 31 (FIGS. 13, 14, and 16). The first communication port 76a is provided at a position closer to the liquid inlet 35 than the filter chamber 71 in the insertion direction (FIG. 13). The first communication port 76a is provided in a position closer to the fifth wall portion 25 where the film member 63 (FIG. 12) is disposed than the sixth wall portion 26 in the X direction (FIG. 13). The second communication port 76 b is provided on the opposite side of the first communication port 76 a across the filter 72 in the insertion direction, and is provided at a position closer to the liquid outlet 33 than the filter chamber 71. The second communication port 76b is provided at a position closer to the sixth wall portion 26 than to the fifth wall portion 25 in the X direction. The first communication port 76a is provided at a position closer to the third corner c3 than the fourth corner c4 of the filter 72 (FIG. 14). The second communication port 76b is provided at a position closer to the first corner c1 than to the second corner c2 of the filter 72.

  As described above, the first communication port 76a is provided at a position closer to the fifth wall portion 25 than the sixth wall portion 26 in the X direction (FIG. 13). Therefore, the liquid that has passed between the reinforcing wall portion 64 and the film member 63 easily flows into the filter chamber 71 through the first communication port 76a. Moreover, the 1st communicating port 76a and the 2nd communicating port 76b are opened on the surface which is slightly raised through the level | step difference 31s (FIG. 13) also in the bottom face 31b. Thereby, it is suppressed that the foreign matter that has settled on the lower surface of the bottom surface 31b gets over the step 31s and flows into the first communication port 76a and the second communication port 76b.

  The rib 73 surrounding the filter chamber 71 is formed so as to surround the filter 72, the first communication port 76a, and the second communication port 76b along their outer peripheral contour lines (FIG. 14). On the outside of the filter chamber 71, reinforcing ribs 79 for increasing the strength around the filter chamber 71 are formed in a lattice shape. Thereby, deformation of the wall around the filter chamber 71 is suppressed, and peeling of the filter 72 and the film member 74 is suppressed.

A2-3-2. Liquid flow in the flow path:
With reference to FIGS. 15 and 16, the flow of the liquid in the flow path 70 will be described. The liquid in the storage chamber 31 flows into the upstream space 71u of the filter chamber 71 through the first communication port 76a and the second communication port 76b (arrow FL in FIG. 15). The liquid flows in the direction opposite to the direction of gravity through the inside of the filter 72 and flows into the downstream space 71d. At this time, the foreign matters and bubbles mixed in the liquid remain in the upstream space 71u. The liquid flowing into the downstream space 71d flows to the outlet channel 78 connected to the downstream space 71d, and flows to the liquid outlet 33 through the outlet channel 78 (arrow FL in FIG. 16).

  Please refer to FIG. In the liquid container 10A, the filter 72 is provided at a position closer to the liquid outlet 33 than the liquid inlet 35 in the insertion direction. Thereby, foreign matters mixed in the liquid injected through the liquid inlet 35 can be settled before reaching the filter 72. Therefore, the foreign matter is prevented from reaching the filter 72, and clogging of the filter 72 due to the foreign matter is suppressed. In addition, even if air bubbles are mixed into the liquid in the storage chamber 31 by injecting the liquid from the liquid inlet 35, the amount of air bubbles reaching the filter 72 can be reduced. Since the distance between the liquid outlet 33 and the filter 72 is short, an increase in pressure loss between the filter 72 and the liquid outlet 33 is suppressed. Therefore, it is possible to reduce the suction force for sucking the liquid generated in the suction pump 524 (FIGS. 26 to 28) of the liquid consuming apparatus 500 to the liquid outlet 33.

  In particular, in the first embodiment, the liquid inlet 35 is provided at a position closer to the second wall portion 22 than the first wall portion 21, and the filter 72 is closer to the first wall portion 21 than the second wall portion 22. The distance between the liquid inlet 35 and the filter 72 is increased. Therefore, it is more difficult for foreign matter in the liquid to reach the filter 72. Further, foreign matters in the liquid can be captured by the plurality of reinforcing wall portions 64 provided between the liquid inlet 35 and the filter 72, and foreign matters reaching the filter 72 can be reduced. Therefore, clogging of the filter 72 is suppressed, and the life of the filter 72 can be extended.

  FIG. 13 illustrates a central axis CX of the liquid inlet 35 and an axis PX that intersects the central axis CX and is parallel to the insertion direction. In the liquid container 10A, the first communication port 76a communicating with the filter chamber 71 is provided at a position shifted from the axis PX. In this configuration, the distance between the first communication port 76a and the center position of the liquid inlet 35 is longer than when the first communication port 76a is on the axis PX. Therefore, the foreign matter that has entered from the liquid inlet 35 reaches the first communication port 76a as much as the distance increases. Therefore, clogging of the filter 72 is further suppressed.

  In the liquid storage container 10A, the filter chamber 71 is provided below the storage chamber 31 (FIG. 15). Therefore, the liquid can be guided from the storage chamber 31 to the filter chamber 71 by gravity, and the inflow of the liquid into the filter chamber 71 is smoothed. Therefore, the flow of the liquid from the liquid storage container 10A to the liquid consumption apparatus 500 can be made smoother, and the liquid supply performance to the liquid consumption apparatus 500 by the liquid storage container 10A can be enhanced.

  In the liquid container 10A, the upstream space 71u of the filter chamber 71 is located below the filter 72 and the downstream space 71d, and the liquid in the filter chamber 71 is filtered in the direction opposite to the direction of gravity. Pass through. Therefore, the foreign matter removed from the liquid by the filter 72 can be settled below the filter 72 by gravity. Therefore, the occurrence of clogging of the filter 72 is further suppressed.

  In the liquid storage container 10A, the storage chamber 31 and the filter chamber 71 are positioned on the −Y direction side of the first communication port 76a provided at a position close to the liquid inlet 35 and the first communication port 76a. The second communication port 76b provided at a position far from 35 communicates with the second communication port 76b. As a result, when liquid is injected into the empty storage chamber 31, the air flows from the first communication port 76a into the upstream space 71u of the filter chamber 71, and the air in the upstream space 71u is supplied from the second communication port 76b. It can escape to the storage chamber 31 (arrow AF of FIG. 15). Therefore, it is possible to prevent air from staying in the upstream space 71u of the filter chamber 71, and due to such air retention, replenishment of the liquid into the filter chamber 71 is inhibited, and the liquid supply performance to the liquid consuming device 500 is suppressed. Is suppressed from decreasing.

  In the liquid storage container 10A, the first corner c1 of the filter 72 is located at a position protruding to the insertion direction side of the second corner c2, and the third corner c3 is the fourth corner. It is located at a position protruding to the opposite side of the insertion direction from c4 (FIG. 14). That is, the first corner c1 is located on the −Y direction side with respect to the second corner c2, and the third corner c3 is located on the + Y direction side with respect to the fourth corner c4. ing. Further, the outer peripheral shape of the liquid passage area PA in the filter 72 surrounded by the filter support wall 75 is also in a shape along the outer peripheral shape of the filter 72. As a result, the outer peripheral shape of the filter 72 is a rectangular shape having corners at the positions of the second corner portion c2 and the fourth corner portion c4, and the outer peripheral shape of the liquid passage region PA is a shape matching that. Rather, the area of the liquid passage area PA in the filter 72 is increased. Therefore, the foreign substance removal effect by the filter 72 is enhanced by that amount. Further, the outer shape of the filter 72 does not match when the front and back are reversed. Therefore, the upper surface and the lower surface of the filter 72 can be easily identified. Therefore, the assembly process of the filter 72 to the container main body 11 of the liquid container 10A is simplified.

  In the liquid container 10A, the filter chamber 71 is exposed to the outside by removing the container lid member 62 from the open housing member 60 (FIGS. 7 and 16). Therefore, replacement and maintenance of the filter 72 can be easily performed.

A2-4. The outlet housing recess and the plurality of recesses of the first wall:
A2-4-1. Exit storage recess:
FIG. 17 is a schematic cross-sectional view of the first wall portion 21 of the liquid container 10A taken along line 17-17 shown in FIG. In the first wall portion 21, the liquid outlet 33 is opened at the distal end of the pipe portion 33 p that protrudes in the −Y direction at a substantially central position of the outlet storage recess 34. The liquid outlet 33 is surrounded by the inner wall surface of the outlet storage recess 34. Accordingly, the liquid spilled from the liquid outlet 33 is received by the outlet storage recess 34, so that the liquid storage container 10A is prevented from being contaminated by the liquid spilled from the liquid outlet 33.

  In the outlet storage recess 34, the depth below the liquid outlet 33 is greater in the + Y direction than above the liquid outlet 33. As a result, the amount of liquid that has leaked downward from the liquid outlet 33 can be stored in the outlet storage recess 34. Therefore, the liquid leaked from the liquid outlet 33 is suppressed from being transmitted to a region below the outlet storage recess 34, and the contamination of the liquid storage container 10A by such liquid is further suppressed.

A2-4-2. Recessed portion of the first wall:
When the liquid container 10 </ b> A is attached to the liquid consumption device 500, the second recess 55 b formed in the first wall portion 21 has a rod 525 (in the container insertion port 521 of the liquid consumption device 500). Is inserted). The rod 525 is constituted by an axial member extending in the + Y direction, and has a shape corresponding to the opening shape and opening depth of the second recess 55b.

  The second recess 55b has a bottom portion 56 on the + Y direction side, and the tip of each rod 525 contacts the bottom portion 56 in the mounted state of the liquid container 10A. Accordingly, when the liquid container 10A is inserted into the liquid consuming apparatus 500, the liquid container 10A is suppressed from being pushed too far toward the −Y direction side from the specified mounting position.

  In the liquid container 10A, the liquid outlet 33 is provided above the second recess 55b that functions as a positioning portion of the liquid container 10A. Therefore, the occurrence of poor connection between the liquid inlet (not shown) of the liquid consuming device 500 connected to the liquid outlet 33 and the liquid outlet 33 due to the displacement of the liquid outlet 33 is suppressed.

  In the liquid container 10A, the second recessed portion 55b has a substantially circular shape in which both ends in the Z direction are cut out flat (FIG. 9). Accordingly, the posture of the liquid container 10A is suppressed from tilting in the Z direction with respect to the central axis of the rod 525 inserted into the second recess 55b.

  In the liquid container 10 </ b> A, a first recess 55 a is provided between the electrical connection portion 50 and the liquid outlet 33. Therefore, even if the liquid container 10 </ b> A is in a posture in which the third wall portion 23 is positioned below the fourth wall portion 24, the liquid spilled from the liquid outlet 33 is transmitted to the electrical connection portion 50. This is suppressed by the first recess 55a. Therefore, deterioration of the electrical connection unit 50 due to adhesion of liquid to the electrical connection unit 50 and a decrease in electrical connectivity of the electrical connection unit 50 to the liquid consuming device 500 are suppressed.

  In the liquid container 10A, a second recess 55b and a third recess 55c are provided below the liquid outlet 33. Therefore, even if the liquid storage container 10 </ b> A is in a posture in which the fourth wall portion 24 is positioned below the third wall portion 23, the liquid spilled from the liquid outlet 33 is transmitted to the fourth wall portion 24. Is suppressed by the two recesses 55b and 55c. Therefore, the expansion of the area contaminated by the liquid spilled from the liquid outlet 33 is suppressed.

  In the liquid container 10A, the center positions in the X direction of the respective recesses 55, the liquid outlets 33, and the electrical connection portions 50 are arranged in a line on an axis CY parallel to the Y direction (FIG. 9). ). Each of these center positions may be arranged at a position slightly shifted from the axis CY. The deviation in the X direction of the center position of each recess 55 with respect to the center position of the liquid outlet 33 and the electrical connection portion 50 may be allowed within a range in which the liquid spilled from the liquid outlet 33 can be collected smoothly. The center position of each recess 55 may be deviated in a range where at least a part of each recess 55 overlaps the liquid outlet 33 and the electrical connection portion 50 when the liquid container 10A is viewed in the Y direction.

A2-5. Configuration on the second end side of the liquid container:
With reference to FIGS. 18-23, the detail about the structure by the side of the 2nd end part 13 of 10 A of liquid storage containers is demonstrated. FIG. 18 is a schematic perspective view showing the configuration of the second end 13 side of the liquid container 10A in a state where the lid member 85 is opened. FIG. 19 is a schematic side view of the upper end portion of the second end portion 13 of the liquid container 10A in a state where the lid member 85 is opened when viewed in the + X direction. FIG. 20 is a schematic plan view when the second end portion 13 of the liquid container 10A in a state where the lid member 85 is opened is viewed in the −Z direction. FIG. 21 is a schematic cross-sectional view of the second end 13 of the liquid container 10A taken along line 21-21 shown in FIG. FIG. 21 illustrates a state in which the lid member 85 is closed. FIG. 22 is a schematic perspective view illustrating the state when the lid member 85 is moved in the closing direction. FIG. 23 is a schematic perspective view showing the state of the liquid injection operation for the liquid storage container 10 </ b> A attached to the liquid consuming apparatus 500.

  As described above, the liquid inlet 35 is provided on the second end 13 side of the liquid container 10 </ b> A, and further, the visual recognition part 38 having the scale 39 and the handle part 40 are provided below the liquid inlet 35. ing. Hereinafter, the scale 39 of the visual recognition unit 38, the handle 40, the configuration around the liquid inlet 35, and the operation of injecting the liquid into the liquid inlet 35 will be described in order.

A2-5-1. Scale of visual recognition part:
The visual recognition part 38 provided in the 2nd wall part 22 is provided with the scale 39 as mentioned above (FIG. 18). In the liquid storage container 10 </ b> A, at least a part of the scale 39 is provided on the outer wall surface 22 o outside the storage chamber 31 in the visual recognition unit 38 and the inner wall surface 22 i inside the storage chamber 31 in the visual recognition unit 38. Hereinafter, the scale 39 provided on the outer wall surface 22o is referred to as an “outer scale 39o”. The scale 39 provided on the inner wall surface 22i is referred to as an “inner scale 39i”.

  The outer scale 39o is configured as a convex portion of the outer wall surface 22o. The convex portion constituting the outer scale 39o has a linear shape extending in the X direction. The outer scale 39o is formed as a lower limit scale 39L indicating the lower limit of the amount of liquid stored in the storage chamber 31. As the outer scale 39o, a scale indicating another liquid amount may be added in addition to the lower limit scale 39L.

  The inner scale 39 i is configured as a plurality of ribs in the accommodation chamber 31. The ribs constituting the inner scale 39i are arranged at predetermined intervals in the vertical direction in the storage chamber 31. Moreover, the rib which comprises the inner scale 39i is provided in the corner | angular part of the 2nd wall part 22 and the 6th wall part 26, and connects the 2nd wall part 22 and the 6th wall part 26, It is comprised as a substantially triangular-shaped wall part extended along a X direction and a Y direction. The plurality of ribs constituting the inner scale 39 i also function as reinforcing ribs that increase the strength of the opening housing member 60.

  The inner scale 39 i includes a lower limit scale 39 </ b> L provided at the lowest position in the accommodation chamber 31. The inner scale 39i constituting the lower limit scale 39L is provided at a position facing the outer scale 39o constituting the lower limit scale 39L in the Y direction.

  According to the liquid container 10A, as the scale 39, an inner scale 39i on the inner wall surface 22i side and an outer scale 39o on the outer wall surface 22o side are provided. Therefore, even if the visibility of a part of the inner scale 39i decreases for some reason, the user can check the amount of liquid in the storage chamber 31 by the outer scale 39o. Similarly, for the outer scale 39o, the amount of liquid in the storage chamber 31 is confirmed by the inner scale 39i even if the visibility is reduced due to wear of the outer scale 39o or adhesion of liquid to the outer scale 39o. it can. In this way, even if a malfunction occurs in either the inner scale 39i or the outer scale 39o, it is possible to prevent the user from being able to check the liquid amount.

  According to the liquid container 10 </ b> A, the outer scale 39 o is configured by the convex portion of the outer wall surface 22 o of the second wall portion 22. Therefore, for example, even if the liquid spilled from the liquid inlet 35 adheres to the outer scale 39o and the visibility of the outer scale 39o decreases, the user can confirm the position of the outer scale 39o by touch.

  According to the liquid container 10A, the inner scale 39i is configured as a rib provided on the inner wall surface 22i. Therefore, when the periphery of the rib is immersed in the liquid stored in the storage chamber 31, the difference in brightness and color between the formation site of the inner scale 39i and the surrounding area increases, and therefore the inner scale 39i Visibility is improved.

  According to the liquid container 10A, the lower limit scale 39L is provided on both the outer wall surface 22o and the inner wall surface 22i. As a result, a decrease in the visibility of the scale 39 indicating the lower limit position is suppressed, so that the liquid container 10A is insufficient in liquid and the liquid supply to the liquid consumption device 500 is prevented from falling. The

A2-5-2. Handle:
As described above, in the liquid container 10A, the handle 40 is provided in the first portion 15 (FIGS. 4 and 21). In the liquid container 10 </ b> A, the operability of the user at the time of attaching / detaching the liquid container 10 </ b> A to the liquid consuming apparatus 500 is enhanced by the handle 40. The handle 40 is provided on the bottom wall 24s of the fourth wall 24 opposite to the upper wall 23s of the third wall 23 where the liquid inlet 35 is open. Accordingly, the liquid spilled from the liquid inlet 35 is suppressed from reaching the handle 40 and the liquid is suppressed from adhering to the handle 40. Therefore, it is possible to suppress liquid from adhering to the user's body via the handle 40.

  As described above, in the liquid container 10A, the convex portion of the outer wall surface 22o that constitutes the outer scale 39o that is the lower limit scale 39L of the visual recognition unit 38 is provided above the handle portion 40. By the convex portion constituting the outer scale 39o, the liquid spilled from the liquid inlet 35 and transmitted to the outer wall surface 22o of the second wall portion 22 can be received. Therefore, it is further suppressed that such liquid reaches the handle portion 40 (FIG. 4).

  In the liquid container 10A, since the handle 40 is provided on the bottom wall surface 24s of the fourth wall 24, the formation area of the handle 40 and the formation area of the visual recognition part 38 provided on the second wall 22 are provided. And the interference is suppressed. Therefore, even when the handle portion 40 is provided, the formation region of the visual recognition portion 38 can be increased. Moreover, it is suppressed that the visual recognition of the visual recognition part 38 by a user will be inhibited by the handle part 40. FIG.

  In the liquid consuming apparatus 500, a plurality of liquid storage containers 10A are mounted in parallel with being arranged in the X direction (FIG. 1). That is, in the liquid consuming apparatus 500, the plurality of liquid storage containers 10A are arranged in a direction that intersects the insertion direction and the direction from the upper wall surface 23s to the bottom wall surface 24s (FIG. 6) (FIG. 6) ( FIG. 1). As described above, if the handle 40 is provided on the bottom wall surface 24s, even if the arrangement interval in the X direction of the liquid container 10A in the liquid consuming device 500 is reduced, the user can access the handle 40. The decrease in is suppressed. Therefore, the arrangement area of the liquid container 10A in the liquid consuming apparatus 500 can be configured more compactly.

  In the liquid container 10A, since the visual recognition unit 38 is provided as described above, in the operation of injecting liquid into the storage chamber 31 through the liquid inlet 35, the liquid is injected from the liquid inlet 35 due to excessive liquid injection amount. Is prevented from overflowing. Therefore, the handle 40 is soiled by the overflowing liquid, and the liquid is suppressed from adhering to the user's body through the handle 40. Further, in the liquid container 10A, the liquid is supplied to the handle portion 40 by various configurations around the liquid inlet 35 that can suppress the leakage of the liquid from the liquid inlet 35 and the diffusion of the liquid leaked from the liquid inlet 35. It is suppressed that it adheres. Thus, in the liquid container 10A, the handle 40 is provided, and the visual recognition unit 38 is configured to be easily seen by the user, so that convenience for the user is enhanced.

A2-5-3. Configuration around the liquid inlet:
(1) Liquid receiving part:
In the liquid container 10A, a liquid receiving portion 80 that receives liquid spilled from the liquid inlet 35 is provided on the upper wall surface 23s of the third wall portion 23 that is the upper surface wall portion (FIGS. 18 and 20). The liquid receiving unit 80 is configured as a recess provided around the liquid inlet 35. The liquid receiving portion 80 is provided at the lower end of the inlet peripheral wall portion 36 (FIG. 18). The liquid receiving portion 80 includes a region between the liquid inlet 35 and the second wall portion 22, a region between the liquid inlet 35 and the fifth wall portion 25, and a space between the liquid inlet 35 and the sixth wall portion 26. In the region (FIG. 20).

  According to the liquid container 10 </ b> A, the liquid spilled from the liquid inlet 35 is received by the liquid receiving unit 80. Therefore, the outer wall surface of the liquid container 10A is prevented from being soiled by the liquid spilled from the liquid inlet 35. Therefore, the liquid spilled from the liquid inlet 35 is prevented from adhering to the user's body. Moreover, it is suppressed that the liquid spilled from the liquid inlet 35 is transmitted to the visual recognition part 38 of the 2nd wall part 22, and the visibility of the scale 39 falls.

  A liquid receiving part partition wall 81 for partitioning the space in the concave part into a plurality of parts is provided in the concave part constituting the liquid receiving part 80 (FIG. 20). The liquid receiving part partition wall 81 is configured by a wall part extending upward in the liquid receiving part 80. In the liquid storage container 10 </ b> A, the internal space of the liquid receiving unit 80 is divided into a plurality of portions by the liquid receiving unit partition wall 81, thereby suppressing the flow of liquid in the liquid receiving unit 80. Spilling is suppressed. Therefore, the outer wall surface of the liquid container 10A is prevented from being soiled by the liquid spilled from the liquid inlet 35. It is further suppressed that the liquid spilled from the liquid inlet 35 adheres to the user's body. A reduction in the visibility of the scale 39 due to the liquid spilled from the liquid inlet 35 is further suppressed.

(2) Convex wall:
In the liquid container 10A, the upper wall surface 23s of the third wall portion 23 is a convex wall portion protruding upward between the liquid inlet 35 and the second wall portion 22, that is, on the + Y direction side of the liquid inlet 35. 82 is formed (FIGS. 18 and 19). The convex wall portion 82 functions as a prevention wall that prevents droplets from splashing in the + Y direction from the liquid inlet 35 in the operation of injecting liquid into the liquid inlet 35 by the user. Therefore, it is possible to prevent the liquid container 10A from being soiled by the liquid and the liquid from being attached to the user's body during the liquid injection operation. Moreover, it is suppressed that the liquid adheres to the outer wall surface 22o of the 2nd wall part 22, and the visibility of the scale 39 falls. In addition, the upper end part of the convex wall part 82 is provided with a notch-shaped concave part 82r that is recessed in the −Z direction (FIG. 18). The function of the recess 82r will be described later.

(3) Lid member:
The liquid container 10A is provided with a lid member 85 that rotates with respect to the upper wall surface 23s of the third wall portion 23 that is the upper surface wall portion to open and close the liquid inlet 35 (FIGS. 18 to 23). . The lid member 85 is coupled to the third wall portion 23 via a coupling portion 86 (FIG. 18). The connecting portion 86 is configured by a hinge mechanism, and the lid member 85 rotates around the rotation axis RX of the connecting portion 86. The connecting portion 86 is provided on the −Y direction side of the liquid inlet 35, and the rotation axis RX is disposed along the X direction. The lid member 85 rotates on the upper wall surface 23s along the Y direction.

  The lid member 85 has a sealing surface 87s facing the liquid inlet 35 and an outer surface 87o on the opposite side (FIG. 19). The sealing surface 87s covers the liquid inlet 35 and closes the liquid inlet 35 as the lid member 85 rotates in the + Y direction (FIG. 21). The sealing surface 87s takes a state in which the liquid inlet 35 is opened away from the liquid inlet 35 as the lid member 85 rotates in the −Y direction (FIGS. 18 and 19).

  According to the liquid container 10A, since the liquid inlet 35 can be closed by the lid member 85 at times other than the liquid injection operation, the liquid from the liquid inlet 35 can be prevented from spilling. Therefore, the contamination of the liquid container 10A due to the liquid spilled from the liquid inlet 35 is suppressed. Moreover, it is suppressed that the liquid which spilled from the liquid inlet 35 adheres to the visual recognition part 38 of the 2nd wall part 22, and the visibility of the scale 39 falls. According to the liquid storage container 10 </ b> A, by closing the liquid inlet 35 with the lid member 85, it is possible to suppress entry of foreign matter from the liquid inlet 35 into the storage chamber 31. Note that when closing the lid member 85, the user can position the lid member 85 with reference to the position of the outer peripheral end portion 66e of the container lid member 62 arranged along the attachment position of the lid member 85. (FIG. 22). Therefore, the operability of the lid member 85 by the user is improved.

  A sealing member 88 is disposed on the sealing surface 87s (FIGS. 18 and 21). When the sealing surface 87s closes the liquid inlet 35, the seal member 88 contacts the upper end surface 36s of the inlet peripheral wall 36 to seal the liquid inlet 35 (FIG. 21). The seal member 88 is made of a resin member such as an elastomer or rubber, for example. In the liquid container 10 </ b> A, the sealing member 88 enhances the closing property of the liquid inlet 35 by the lid member 85, so that leakage of the liquid from the liquid inlet 35 is further suppressed. Therefore, the contamination of the liquid container 10A due to the liquid spilled from the liquid inlet 35 and the decrease in the visibility of the scale 39 are further suppressed.

  In the liquid container 10A, the third wall portion 23 is provided with a stopper portion 89 that restricts the rotation of the lid member 85 in the −Y direction (FIGS. 18, 19, and 21). The stopper portion 89 supports the lid member 85 in an inclined state with respect to the upper wall surface 23s of the third wall portion 23 so that the state in which the liquid inlet 35 is opened is maintained (FIG. 19). The stopper portion 89 is provided as a convex structure of the upper wall surface 23 s provided on the −Y direction side of the connecting portion 86.

  The stopper portion 89 has an inclined surface 89s having an inclination angle with respect to the upper wall surface 23s (FIGS. 19 and 21). The inclined surface 89s of the stopper portion 89 rotates the lid member 85 in a direction to open the liquid inlet 35, and when the angle θ with respect to the upper wall surface 23s of the lid member 85 reaches a predetermined angle, the lid member 85 It contacts the lower end of the outer surface 87o (FIG. 19). The lid member 85 receives a reaction force against its own weight from the inclined surface 89s of the stopper portion 89, and is supported in a state inclined with respect to the upper wall surface 23s.

  According to the liquid container 10 </ b> A, the lid member 85 is prevented from obstructing the injection operation when the user injects the liquid into the liquid inlet 35. Therefore, the user can be prevented from accidentally spilling the liquid during the liquid injection operation, and the liquid container 10A can be prevented from being soiled by the spilled liquid and the visibility of the scale 39 being lowered. Further, when the user tries to rotate the lid member 85 to close the liquid inlet 35, the lid member 85 is in an inclined state, so that the user can easily place a finger on the outer surface 87o of the lid member 85, It is easy to lift the lid member 85. Therefore, the operability of the lid member 85 is improved.

  In the first embodiment, the angle θ on the + Y direction side between the lid member 85 and the upper wall surface 23s when the lid member 85 is supported by the stopper portion 89 is 100 ° or more. This further suppresses the lid member 85 from interfering with the operation of injecting the liquid into the liquid inlet 35 by the user. Further, when the liquid is injected, the liquid droplets 35 scattered from the liquid inlet 35 in the −Y direction can be received by the lid member 85. Therefore, the contamination of the liquid container 10A due to the liquid droplets scattered from the liquid inlet 35 is suppressed.

  On the outer surface 87o of the lid member 85, an outer surface convex portion 90 protruding from the outer surface 87o is provided at the end on the tip side opposite to the base end side connected by the connecting portion 86 (see FIG. 18, FIG. 19). The user can put his / her finger on the outer convex portion 90 when opening / closing the lid member 85. Therefore, the operation of the lid member 85 by the user is smoothed, and the operability of the lid member 85 is improved.

  The outer surface convex portion 90 includes a sealing surface side concave portion 91 which is a concave portion provided in the sealing surface 87s (FIGS. 18 and 21). When the lid member 85 closes the liquid inlet 35, the sealing surface side concave portion 91 receives and stores the convex wall portion 82 therein (FIG. 21). The convex wall portion 82 can be used as a positioning reference when the lid member 85 is closed, for example. When the user closes the liquid inlet 35 by the lid member 85, the user can open and close the lid member 85 by rotating the outer surface convex portion 90 toward the convex wall portion 82 using the convex wall portion 82 as a mark. To be smoothed.

  A locking portion 93 extending in the shape of a tongue piece is provided at the tip of the lid member 85 in a direction intersecting the sealing surface 87s (FIGS. 18 and 21). When the lid member 85 closes the liquid inlet 35, the locking portion 93 is formed with a claw portion 93 c related to the locked portion 94 that is a recess opening in the + Y direction at the upper end of the second wall portion 22. Has been. When the locking portion 93 of the lid member 85 is locked to the locked portion 94, the sealing performance of the liquid inlet 35 by the lid member 85 is enhanced. Further, when the lid member 85 is in a state of closing the liquid inlet 35, the locking portion 93 protrudes from the second wall portion 22 in the + Y direction (FIG. 6). Accordingly, when the lid member 85 is opened, the user can easily place a finger on the lower surface of the locking portion 93. The locking portion 93 extends obliquely downward from the upper end of the second wall portion 22. Accordingly, when the user puts his finger on the lower surface of the locking portion 93 and tries to rotate the lid member 85 in the + Z direction, the claw portion 93c is separated from the locked portion 94 in the locking portion 93. Force in the direction to work. Therefore, it is easy to remove the locking portion 93 from the locked portion 94.

  When the lid member 85 is in a state of closing the liquid inlet 35, the locking portion 93 of the lid member 85 is disposed on the second wall portion 22 (FIG. 8). An end portion on the −X direction side of the second wall portion 22 is configured by a peripheral wall portion 68 of the container lid member 62. The upper end portion 68e of the peripheral wall portion 68 has a locking portion so that a gap with a predetermined interval is formed between the upper end portion 68e and the distal end of the locking portion 93 when it is disposed on the second wall portion 22. It is located below the arrangement position of the tip of 93. Accordingly, a recess is formed on the outer wall surface 22 o of the second wall portion 22 along the outer peripheral shape of the tip of the locking portion 93. The user recognizes that when the lid member 85 is closed, the distal end of the locking portion 93 should be moved to the position of the upper end portion 68 e of the peripheral wall portion 68. As described above, the upper end portion 68 e of the peripheral wall portion 68 of the container lid member 62 functions as a positioning portion for the locking portion 93 for reliably closing the liquid inlet 35 by the lid member 85.

  A protrusion 95 protruding from the sealing surface 87 s is provided at the end of the sealing surface 87 s of the lid member 85 on the second wall 22 side (FIG. 18). The protrusions 95 are provided at an end on the + X direction side and an end on the −X direction side. The protruding portion 95 is provided between the connecting portion 86 and the seal member 88. The protrusion 95 is provided with a groove 96. The groove portion 96 extends along the protruding direction in which the protruding portion 95 protrudes, and has a bottom portion 96t on the rotation axis RX side of the lid member 85 (FIGS. 18 and 20).

  The groove 96 of the protrusion 95 is in a state in which the liquid receiving portion 80 is positioned ahead of the protrusion 95 in the protruding direction while the lid member 85 is rotated toward the liquid inlet 35 (FIG. 22). . The liquid adhering to the sealing surface 87s of the lid member 85 is transmitted to the groove portion 96 by gravity while the lid member 85 is in a state where the liquid inlet 35 is opened (FIG. 18). When the liquid inlet 35 is to be closed by the lid member 85, the liquid accumulated in the groove 96 is guided to the groove 96, flows to the liquid receiver 80, and is stored in the liquid receiver 80 (FIG. 22). .

  Thus, the protrusion 95 functions as a ridge that guides the liquid adhering to the sealing surface 87 s to the liquid receiver 80. Accordingly, the liquid adhering to the sealing surface 87s of the lid member 85 is prevented from being transmitted to other parts other than the liquid receiving portion 80, and the liquid container 10A is prevented from being contaminated by the liquid. In addition, it is possible to prevent the liquid attached to the sealing surface 87 s of the lid member 85 from being transmitted to the second wall portion 22 and attached to the visual recognition portion 38, and the visibility of the scale 39 being lowered.

A2-5-4. Injecting liquid into the liquid inlet:
The liquid injection operation for the liquid inlet 35 will be described with reference to FIGS. In the liquid injection operation, the liquid injection tool 600 is used (FIG. 23). The liquid injection tool has a configuration in which a cylindrical spout 602 for allowing the liquid inside the bag-like member 601 to flow out is attached to the end of the bag-like member 601 that contains the liquid therein. The spout 602 extends from the bag-like member 601. The bag-like member 601 has an overhang portion 603. The overhang portion 603 is a portion projecting in a direction intersecting the direction in which the spout 602 extends from the portion where the spout 602 is attached.

  The user performs the liquid injection operation with the opening end of the spout 602 facing the liquid inlet 35 and the bag-shaped member 601 tilted. The user can confirm the amount of liquid stored in the storage chamber 31 with reference to the scale 39 of the visual recognition unit 38 during the liquid injection operation.

  In FIG. 18, the position of the liquid injection tool 600 when the liquid injection operation is performed is illustrated by a one-dot chain line. As described above, the concave portion 82r is provided at the upper end portion of the convex wall portion 82 provided on the upper wall surface 23s of the third wall portion 23 of the container body 11. A concave portion 98 that is recessed in the −Y direction and the −Z direction is provided at the corner portion between the second wall portion 22 and the third wall portion 23 of the container body 11. The two concave portions 82r and 98 are provided so as to be aligned with the liquid inlet 35 in the Y direction. More specifically, the two concave portions 82r and 98 are provided so as to intersect with the central axis CX of the liquid inlet 35 and to be positioned on the axis PX parallel to the Y direction (FIG. 20).

  During the liquid injection operation, the two concave portions 82 r and 98 receive a part of the liquid injection tool 600. The two concave portions 82r and 98 support the liquid injection tool 600 by receiving a gusset portion that is an end portion of the overhang portion 603 of the liquid injection tool 600. Hereinafter, the recesses 82r and 98 are also referred to as “support recesses 82r and 98”, respectively. In order to distinguish the two, the recess 82r is also referred to as “first support recess 82r”, and the recess 98 is also referred to as “second support recess 98”.

  According to the liquid container 10A, when the liquid injection tool 600 is supported by the first support recess 82r during the liquid injection operation, the posture of the liquid injection tool 600 becomes unstable and the liquid spills. Is suppressed. In particular, if the liquid injection tool 600 is supported at the two points of the first support recess 82r and the second support recess 98, the stability of the posture of the liquid injection tool 600 during the liquid injection operation is further enhanced. Further, according to the liquid container 10A, the liquid transmitted from the liquid injection tool 600 to the convex wall portion 82 can be received by the first support concave portion 82r at the upper end. Therefore, it is further suppressed that the liquid adheres to the outer wall surface of the liquid container 10A. Further, the reduction in the visibility of the scale 39 due to the liquid spilled from the liquid inlet 35 is further suppressed.

A2-5-5. Details of the inner wall:
In the storage chamber 31, an inner wall portion 65 hangs down in the vicinity of the liquid inlet 35 (FIG. 21). In the first embodiment, the inner wall portion 65 is provided such that its wall surface continuously extends from the inner peripheral surface of the liquid inlet 35 on the −Y direction side. According to the liquid storage container 10 </ b> A, the liquid poured from the liquid inlet 35 can be smoothly guided to the bottom surface 31 b of the storage chamber 31 through the inner wall portion 65 during the liquid injection operation. . Therefore, the liquid poured from the liquid inlet 35 suppresses the liquid in the storage chamber 31 from foaming, and the bubbles are prevented from being mixed into the liquid. For this reason, a decrease in the supply of liquid to the liquid consuming apparatus 500 due to bubbles in the liquid is suppressed.

  In addition, the bubbling of the liquid in the storage chamber 31 makes the position of the liquid surface visually recognized from the visual recognition unit 38 unclear and makes it difficult for the user to check the amount of liquid via the visual recognition unit 38. It is suppressed. Therefore, it is possible to prevent liquid from spilling from the liquid inlet 35 due to an excessive amount of liquid injected. In addition, since the introduction of the liquid into the storage chamber 31 is facilitated by the inner wall portion 65, it is possible to suppress the occurrence of liquid droplets scattered outside the storage chamber 31 through the liquid inlet 35 during the liquid injection. . Therefore, contamination of the liquid container 10A and the user's body due to such droplets is suppressed.

  It is desirable that the inner wall 65 is provided at a position where at least a part of the inner wall 65 can be seen when the liquid inlet 35 is viewed from the outside of the container body 11 (FIG. 20). Thus, the user can visually recognize the position of the inner wall portion 65 during the liquid injection operation, and can prompt the user to pour the liquid toward the inner wall portion 65. In this case, the direction in which the liquid inlet 35 is viewed from the outside of the container body 11 does not have to be in the −Z direction as shown in FIG. 20, and is directed from the user position during the liquid injection operation toward the liquid inlet 35. Direction is good.

  The upper end of the inner wall portion 65 is connected to the third wall portion 23, and the end portion on the + X direction side is connected to the sixth wall portion 26 (FIG. 10). Thereby, the strength of the opening housing member 60 is increased. Further, the end surface on the + X direction side of the inner wall portion 65 is welded to the film member 63 (FIG. 12). Accordingly, in the liquid container 10A, the welding area of the film member 63 is increased by the arrival area of the inner wall portion 65, and the bonding strength of the film member 63 to the opening housing member 60 is increased. Thus, in the liquid storage container 10A, the inner wall portion 65 functions as a reinforcing rib in the storage chamber 31 that enhances the strength and durability of the liquid storage container 10A.

  In the liquid container 10A, the lower end 65e of the inner wall portion 65 is located above the bottom surface 31b (FIG. 11). Therefore, when the liquid in the storage chamber 31 is consumed in the liquid consuming device 500, the inner wall 65 suppresses the liquid from remaining in the region A2 on the + Y direction side from the inner wall 65. In the first embodiment, the lower end 65 e of the inner wall portion 65 is provided at a position closer to the bottom surface 31 b than the top surface 31 u of the storage chamber 31. The lower end 65e of the inner wall portion 65 is located above the lower limit scale 39L. More specifically, the lower end 65e of the inner wall portion 65 is (1/4) · H or less from the height of the lower limit scale 39L, where H is the distance in the Z direction between the upper surface 31u and the lower limit scale 39L. Located at height. Thus, the state in which the inner wall portion 65 is in contact with the liquid is maintained until the position of the liquid level approaches the position of the lower limit scale 39L. Therefore, it is possible to obtain the effect of suppressing the bubbling of liquid and the generation of liquid droplets in the storage chamber 31 in the liquid injection operation as described above in a wide range until the liquid in the storage chamber 31 approaches the lower limit amount. it can.

  The inner wall portion 65 has an end convex portion 101 projecting along the insertion direction at the lower end 65e (FIG. 21). The end convex portion 101 is formed as a portion that locally increases in thickness at the lower end 65 e of the inner wall portion 65 and protrudes from the wall surface of the inner wall portion 65. In the first embodiment, the end protrusion 101 protrudes in the + Y direction toward the liquid inlet 35 side. Therefore, during the liquid injection operation when the position of the liquid level in the storage chamber 31 is located below the end convex portion 101, the end convex portion 101 causes the liquid flowing downward through the inner wall portion 65. You can cut down the momentum. Therefore, even when the position of the liquid level in the storage chamber 31 is located below the lower end 65e of the inner wall portion 65, the bubbling of the liquid in the storage chamber 31 during the liquid injection operation can be suppressed. it can. In addition, the generation of liquid droplets due to the liquid colliding with the liquid level in the storage chamber 31 is suppressed. Therefore, it is suppressed that such droplets are scattered outside through the liquid inlet 35 and the outer wall surface of the liquid container 10A and the user's body are contaminated. In the first embodiment, the upper surface of the end convex portion 101 facing the + Z direction constitutes a plane along the Y direction. Therefore, the momentum of the liquid flowing along the inner wall portion 65 can be more effectively reduced, and the foaming of the liquid in the storage chamber 31 and the scattering of the droplet from the liquid inlet 35 as described above are further suppressed. Is done.

  In the liquid storage container 10 </ b> A, since the inner wall portion 65 has the end convex portion 101, the connection portion between the inner wall portion 65 and the inner wall surface 26 s of the storage chamber 31 is enlarged. Therefore, the inner wall portion 65 is more firmly fixed to the inner wall surface 26s of the storage chamber 31. Moreover, the welding area with the film member 63 in the lower end 65e of the inner wall part 65 is increasing by the edge part convex part 101 (FIG. 12). Therefore, peeling of the film member 63 from the inner wall 65 is suppressed from the lower end 65e of the inner wall 65. As described above, in the liquid container 10A, the end convex portion 101 of the inner wall portion 65 enhances the fixability of the inner wall portion 65 to the wall portions 25 and 26, and the function of the inner wall portion 65 as a reinforcing rib is more enhanced. It is even higher.

  The upper end of the inner wall portion 65 is provided with a communication portion 102 that allows two adjacent regions in the storage chamber 31 partitioned by the inner wall portion 65 in the insertion direction to communicate with each other (FIG. 11). The communication portion 102 is formed as a flow path between the concave portion that is locally recessed in the + X direction at the end on the −X direction side of the inner wall portion 65 and the film member 63 (FIGS. 11 and 12). ). As a result, during the operation of injecting the liquid from the liquid inlet 35, the air present in the region on the insertion direction side from the inner wall portion 65 in the storage chamber 31 is released to the liquid inlet 35 through the communication portion 102. Can do. Therefore, the operation of injecting the liquid into the liquid container 10A is further facilitated.

Therefore, the liquid is prevented from leaking from the container atmosphere port 112.

  In the air introduction part 110 of the liquid container 10A, the air passage 113 has an inclined wall surface 118 (FIG. 25). Therefore, even if liquid enters the atmospheric passage 113 through the storage chamber atmospheric port 111, the liquid is guided to the storage chamber atmospheric port 111 along the inclined wall surface 118 by gravity and returned to the storage chamber 31. Therefore, the liquid in the storage chamber 31 is prevented from leaking through the air introduction unit 110.

  In the atmosphere introduction part 110 of the liquid storage container 10A, the storage chamber atmosphere port 111 is provided at a central portion in the Y direction of the storage chamber 31 (FIG. 25). In the central portion of the storage chamber 31 in the Y direction, the displacement of the liquid surface when the liquid level of the storage chamber 31 swings so that both ends of the storage chamber 31 in the Y direction are alternately displaced up and down is relatively small. Therefore, even if the liquid level of the storage chamber 31 fluctuates greatly, the liquid in the storage chamber 31 is prevented from entering the air introduction part 110 through the storage room air inlet 111, and the liquid storage container through the air introduction part 110 is suppressed. Liquid leakage to the outside of 10A is suppressed. In the liquid storage container 10 </ b> A of the first embodiment, the Y direction coincides with the longitudinal direction of the storage chamber 31. In such a storage chamber 31, the liquid is liable to oscillate in which the liquid surface positions are alternately displaced at both ends in the longitudinal direction. Further, the displacement of the liquid level is further suppressed at the central portion in the longitudinal direction when such oscillation occurs as compared with other portions. Therefore, in the liquid storage container 10A in which the storage chamber 31 has a shape whose longitudinal direction is the Y direction, the liquid can be further prevented from entering the storage chamber atmosphere port 111 due to the oscillation of the liquid. The The above-described rocking of the liquid level in the storage chamber 31 is performed when, for example, an operation of stirring the liquid in the storage chamber 31 by shaking the liquid storage container 10A is performed, or when the liquid storage container 500 is in contact with the liquid consuming device 500. This occurs when the liquid container 10A is transported during the attachment / detachment operation of 10A.

  In the atmosphere introduction section 110 of the liquid container 10A, the atmosphere passage 113 is partitioned into a first atmosphere passage section 121 and a second atmosphere passage section 122 by a passage partition wall 116 (FIGS. 24A and 24B, FIG. 25). Therefore, even if the liquid enters the atmosphere introduction part 110 through the storage room atmosphere port 111, the liquid is suppressed from moving from the first atmosphere passage part 121 to the second atmosphere passage part 122. Therefore, the leakage of the liquid to the outside of the liquid storage container 10A through the air introduction unit 110 is suppressed.

  In the atmosphere introduction part 110 of the liquid container 10A, the accommodation room atmosphere port 111 is provided at an end of the first atmosphere passage 121 opposite to the passage partition wall 116 (FIGS. 24B and 25). Thus, since the storage chamber atmosphere port 111 is provided at a position away from the passage partition wall 116, the liquid that has entered the first atmosphere passage portion 121 from the storage chamber atmosphere port 111 reaches the passage partition wall 116. It is suppressed.

  Further, in the liquid storage container 10A, the passage partition wall 116 is provided at a position closer to the container atmosphere port 112 and the through passage 115 than the storage chamber atmosphere port 111, and the storage chamber atmosphere port 111, the passage partition wall 116, and the like. Is even longer (FIGS. 24B and 25). Therefore, it is further suppressed that the liquid that has entered the first atmospheric passage portion 121 reaches the passage partition wall 116.

  In the liquid storage container 10 </ b> A, passage ribs 123 are provided in each of the first atmospheric passage portion 121 and the second atmospheric passage portion 122. Thereby, it is suppressed that the circulation path of air | atmosphere will be interrupted | blocked in each atmospheric passage part 121,122 by the deformation | transformation of the wall part which comprises the atmospheric passage 113. Further, in the first atmospheric passage portion 121, the liquid that has entered the first atmospheric passage portion 121 is suppressed by the passage rib 123 from reaching the passage partition wall 116. In the second atmospheric passage portion 122, as described above, the end portion of the passage rib 123 on the −X direction side is located on the −X direction side of the end portion on the −X direction side of the through channel. As a result, the liquid that has reached the second atmospheric passage portion 122 is prevented from entering the through flow path 115.

  In the liquid container 10A, an air communication portion 117 that communicates the first air passage portion 121 and the second air passage portion 122 is provided at the upper end of the passage partition wall 116 (FIGS. 24B and 25). This further suppresses the liquid that has entered the first atmospheric passage portion 121 from reaching the second atmospheric passage portion 122 over the passage partition wall 116.

  In the atmosphere introduction part 110 of the liquid container 10A, the container atmosphere port 112 is connected at the end of the second atmosphere passage part 122 opposite to the passage partition wall 116 (FIGS. 24B and 25). As described above, since the container atmosphere port 112 is connected to the second atmosphere passage portion 122 at a position away from the passage partition wall 116, the liquid that has entered the second atmosphere passage portion 122 beyond the passage partition wall 116 has entered. Reaching the container atmosphere port 112 is further suppressed. Further, in the liquid container 10A, since the connection position of the container atmosphere port 112 with respect to the second atmosphere passage portion 122 is a position close to the upper end of the second atmosphere passage portion 122, the liquid in the second atmosphere passage portion 122 is stored in the container. It is even more difficult to reach the atmosphere port 112.

  As described with reference to FIGS. 11 and 12, in the liquid storage container 10 </ b> A, the recesses 61 a, 61 b, 61 c of the opening housing member 60 are closed by the film member 63, thereby introducing the storage chamber 31 and the atmosphere. A portion 110 and an outlet channel 78 are formed. Thus, according to the liquid storage container 10A, the storage chamber 31, the outlet channel 78, and the air introduction part 110 are simply configured in the container main body 11 with a simple configuration.

A2-7. Attaching the liquid container to the liquid supply unit:
26, 27, and 28 will be described with reference to FIG. 26, FIG. 27, and FIG. FIG. 26 is a schematic perspective view showing a liquid supply unit 520 to which a plurality of liquid storage containers 10A are attached. FIG. 27 is a schematic plan view of the liquid supply unit 520 on which a plurality of liquid containers are mounted as viewed in the −Z direction. FIG. 28 is a schematic cross-sectional view of the liquid container 10A and the liquid supply unit 520 in the section 28-28 shown in FIG. In FIG. 28, the hatching of the cross section is omitted for convenience.

  The liquid supply unit 520 has a liquid supply pipe 523 extending in the + Y direction (FIG. 28). When the liquid storage container 10A is attached, the + Y direction end of the liquid supply pipe 523 is inserted into and connected to the liquid outlet 33 of the liquid storage container 10A. The liquid supply pipe 523 is connected to a flexible tube 513 (FIGS. 26 to 28). The liquid supply unit 520 causes the liquid in the storage chamber 31 of the liquid storage container 10 </ b> A to flow out from the liquid outlet 33 to the liquid supply pipe 523 by the suction force generated by the suction pump 524, and the liquid is supplied to the head 511 through the tube 513. (Fig. 1).

  The liquid supply unit 520 includes the rod 525 described with reference to FIG. 17 below the liquid supply pipe 523 (FIG. 28). The rod 525 extends in the + Y direction in parallel with the liquid supply pipe 523. As described above, the rod 525 is inserted into the second recess 55b of the liquid storage container 10A when the liquid storage container 10A is attached to the liquid supply unit 520.

  The liquid supply unit 520 further includes a device-side terminal unit 526 above the liquid supply pipe 523 (FIG. 28). The device-side terminal portion 526 has a connection terminal 527 that is in electrical contact with the electrical connection portion 50 of the liquid container 10A. As described above, when the liquid container 10A is attached to the liquid supply unit 520, the connection terminal 527 of the device-side terminal unit 526 contacts the electrode plate 53 (FIG. 9) of the electrical connection unit 50 from above.

  The liquid supply unit 520 has an identification member 528 on the bottom surface thereof. The identification member 528 is configured as a rectangular structure projecting upward from the bottom surface. When the liquid storage container 10A is attached to the liquid supply unit 520, the identification member 528 is stored in the recess 58 provided at the corner of the lower end of the first wall 21 of the liquid storage container 10A.

  The inner wall surfaces of the recesses 58 of the plurality of liquid storage containers 10A attached to the liquid consumption device 500 have different shapes depending on the type of liquid stored (for example, the color of ink in the first embodiment). doing. The identification member 528 of the liquid supply unit 520 has a shape that fits into the shape of the inner wall surface of the recess 58 of the liquid container 10A to be mounted. Thereby, it is suppressed that 10 A of liquid storage containers will be inserted in the wrong mounting part.

A2-8. Rail function:
Refer to FIG. A guide groove 522 extending along the Y direction is provided at the upper end of the container insertion port 521 included in the liquid supply unit 520 of the liquid consumption apparatus 500. The guide groove 522 has a shape that protrudes on the upper wall surface 23s of the liquid storage container 10A and fits the first rail portion 41 extending along the insertion direction. A guide groove 522 is provided at the lower end of the container insertion port 521. The guide groove 522 has a shape that protrudes from the bottom wall surface 24s of the liquid storage container 10A and fits in the second rail portion 42 that extends along the insertion direction. (FIG. 28).

  When the liquid storage container 10 </ b> A is attached to the liquid consumption device 500, the insertion of the liquid storage container 10 </ b> A into the container insertion port 521 is guided by inserting the first rail portion 41 into the guide groove 522. Accordingly, the user can easily attach and detach the liquid container 10A with respect to the liquid supply unit 520 of the liquid consumption apparatus 500. In particular, in the liquid storage container 10A, since the insertion of the liquid storage container 10A is guided by the two rail portions 41 and 42 provided on the upper and lower sides, the liquid storage when the liquid storage container 10A is inserted into the liquid consumption device 500 is stored. The posture of the container 10A is further stabilized.

  The two rail portions 41 and 42 extend in the + Y direction from the guide groove 522 in the mounted state. Thus, the insertion of the liquid container 10A is guided until the mounting on the liquid consuming device 500 is completed. In addition, since the length of the two rail portions 41 and 42 in the Y direction is long, the liquid storage container 10A is in a stable posture with respect to various liquid consumption devices of a type in which the length of the guide groove in the Y direction is long. An insert operation is possible.

  The manufacturing process of the liquid container 10A will be described with reference to FIGS. The rail portions 41 and 42 function as reference portions for positioning when the liquid container 10A is assembled.

  In the first step, an opening housing member 60 is prepared (FIG. 10). In this step, the rail portions 41 and 42 may be used as a handling portion for handling the opening housing member 60. In the first step, the electrical connection portion 50 is attached in the recess 51 of the opening housing member 60. Further, the filter 72 is disposed in the filter chamber 71 of the opening housing member 60, and the filter chamber 71 is sealed by the film member 74. In the first step, the film member 63 is welded to the opening housing member 60, and the openings of the recesses 61a, 61b, 61c of the opening housing member 60 are closed at once (FIG. 12).

  In the second step, the container lid member 62 (FIG. 10) is attached to the open housing member 60 to which the film member 63 is welded. In a state where the container lid member 62 is appropriately attached to the opening housing member 60, the end surface 67t on the + X direction side of the peripheral wall portion 67 of the container lid member 62 abuts on the rail portions 41 and 42 (FIG. 5). FIG. 7). The end surface 67t on the + X direction side of the peripheral wall portion 67 is in contact with the rail portions 41 and 42 in a contact area CA extending linearly along the insertion direction. In the second step, the film member 63 is covered with the main body wall portion 66 of the container lid member 62, and the filter chamber 71 is sealed with the filter chamber wall portion 67 f that is a part of the peripheral wall portion 67. The film member 74 is covered (FIG. 7).

  As described above, in the second step, the peripheral wall portion 67 of the container lid member 62 abuts on the rail portions 41 and 42 when the container lid member 62 is attached to the opening housing member 60, and the container lid member 62 It functions as a positioning portion for positioning 62. The rail portions 41 and 42 function as a reference portion for positioning the container lid member 62.

  According to the liquid container 10 </ b> A, the container lid member 62 is positioned with respect to the rail portions 41 and 42 that are easily visible and conspicuous in the open housing member 60. Therefore, it is possible to prevent a gap from being generated between the container lid member 62 and the open housing member 60 when the liquid storage container 10A is manufactured. Therefore, foreign matter is prevented from entering the liquid container 10A through such a gap. Therefore, for example, the occurrence of a failure of the liquid container 10A due to the entry of such foreign matter, such as the film members 63 and 74 being torn, is suppressed.

  According to the liquid container 10 </ b> A, the peripheral wall portion 67 contacts the rail portions 41 and 42 in the contact area CA that extends linearly along the insertion direction. As described above, since the contact area between the positioning portion and the reference portion is large, the positioning accuracy of the container lid member 62 with respect to the rail portions 41 and 42 is increased. Therefore, the occurrence of a gap between the opening housing member 60 and the container lid member 62 is further suppressed.

  According to the liquid container 10A, the rail portions 41 and 42 are provided at the central portion in the X direction of the upper wall surface 23s or the bottom wall surface 24s. Therefore, in the manufacturing process, the peripheral wall portion 67 of the container lid member 62 is in contact with the outer wall surface of the opening housing member 60 in order to bring the peripheral wall portion 67 of the container lid member 62 into contact with the rail portions 41 and 42. It will be pushed in so as to ride deeply in the X direction. Therefore, generation | occurrence | production of the clearance gap between the opening housing member 60 and the container cover member 62 is further suppressed. In the liquid container 10A, the filter chamber wall portion 67f of the peripheral wall portion 67 is also in contact with the end portion on the −Y direction side of the second rail portion 42 as one of positioning portions for positioning the container lid member 62. It works (FIG. 7). As a result, the generation of a gap between the opening housing member 60 and the container lid member 62 is further suppressed.

  In the manufacturing process of the liquid container 10A, rail parts 41 and 42 that function as guide parts when the liquid container 10A is attached to and detached from the liquid consuming device 500 are used as a reference for positioning the container lid member 62. Therefore, it is more efficient than the case where a new positioning portion for the container lid member 62 is provided in the opening housing member 60.

  In the second step described above, the position where the concave portion constituting the liquid receiving portion 80, the liquid inlet 35, and the lid member 85 are attached is used as a mark for the arrangement position of the outer peripheral end 62e of the container lid member 62. A lid member 62 can be attached. That is, the outer peripheral end portion 66e of the container lid member 62 can be used as one of positioning portions when the container lid member 62 is attached to the opening housing member 60. As a result, the occurrence of a gap between the opening housing member 60 and the container lid member 62 is suppressed. Even if there is a gap between the outer peripheral end 62e of the container lid member 62 and the opening housing member 60, the foreign matter is received by the concave portion constituting the liquid receiving portion 80, so that the foreign matter enters the gap. Is suppressed. Further, since the liquid spilled from the liquid inlet 35 is received by the liquid receiving portion 80, the deterioration of the container lid member 62 due to contamination is suppressed. Therefore, when removing the container lid member 62 from the opening housing member 60, it is possible to prevent the liquid from adhering to the body of the person who performs the work.

  In the second step, the container lid member 62 can be attached to the opening housing member 60 using the handle portion 40 as a mark of the arrangement position of the end portion 67e of the container lid member 62. That is, the end portion 67e of the container lid member 62 can also be used as one of positioning portions when the container lid member 62 is attached to the opening housing member 60. Thus, in the liquid container 10A, the container lid member 62 has a plurality of portions that can function as positioning portions. Accordingly, the occurrence of a gap between the opening housing member 60 and the container lid member 62 is further suppressed.

A3. Summary of the first embodiment:
As described above, according to the liquid container 10A of the first embodiment, the container lid member 62 is positioned with respect to the rail portions 41 and 42 of the opening housing member 60. It is possible to prevent a gap from being generated between 62 and the opening housing member 60. Therefore, foreign matter can be prevented from entering the liquid storage container 10A from such a gap, and the occurrence of failure of the liquid storage container due to the entry of the foreign matter can be suppressed. Further, at the time of manufacturing, the rail portions 41 and 42 that function as guide portions when the liquid container 10A is attached to and detached from the liquid consuming device 500 are used as a reference for positioning the container lid member 62, which is efficient. . Furthermore, according to the liquid container 10A of the first embodiment, the adhesion of the liquid to the outer surface of the container body 11 is suppressed, and deterioration due to the contamination of the liquid container 10A is suppressed. In addition, according to the liquid container 10A of the first embodiment, various functions and effects described in the first embodiment can be obtained.

FIG. 29 illustrates an axis HX parallel to the horizontal direction when the liquid container 10A is in the mounted state. The configuration of the liquid storage container 10B of the second embodiment is the same as that of the liquid storage container 10A of the first embodiment except that the storage chamber 31 has a bottom surface 31bB that is inclined and the reinforcing wall portion 64 is omitted. The configuration is almost the same. The liquid container 10B of the second embodiment is attached to the liquid consumption device 500 described in the first embodiment.

  In the liquid storage container 10B of the second embodiment, the bottom surface 31bB of the storage chamber 31 is inclined downward toward the filter chamber 71 so that the filter chamber 71 side is positioned below the liquid inlet 35 side in the insertion direction. . The bottom surface 31bB of the storage chamber 31 is inclined so as to gradually become lower in the -Y direction. Thereby, the fluidity | liquidity of the liquid to the filter chamber 71 can be improved more, and the supply performance of the liquid with respect to the liquid consumption apparatus 500 of the liquid storage container 10B is improved. Further, even when the liquid in the storage chamber 31 is reduced, the remaining liquid can be guided to the filter chamber 71 by the inclination of the bottom surface 31bB with respect to the horizontal. Therefore, it is suppressed that the liquid remains in the storage chamber 31. Therefore, even though the user confirms that the liquid remains through the visual recognition unit 38, the supply of the liquid from the liquid container 10B to the liquid consuming device 500 may suddenly stop. It is suppressed. The bottom surface 31bB can promote the flow of the liquid to the filter chamber 71, but has a slight inclination to the extent that the foreign matter settled on the bottom surface 31bB is suppressed from being guided to the filter chamber 71. It is desirable to have a corner. In addition, also in the storage chamber 31 of 2nd Embodiment, the reinforcement wall part 64 (FIG. 11) demonstrated in 1st Embodiment may be provided.

  As described above, according to the liquid container 10B of the second embodiment, the liquid supply performance to the liquid consuming device 500 is improved by having the bottom surface 31bB of the storage chamber 31 inclined toward the filter chamber 71. It has been. In addition, according to the liquid container 10B of the second embodiment, various effects similar to those of the liquid container 10A of the first embodiment can be achieved.

C. Third embodiment:

FIG. 30 is a schematic cross-sectional view schematically showing the configuration of the cut surface along the Y direction of the filter chamber 71 provided in the liquid container 10C of the third embodiment. The configuration of the liquid container 10C of the third embodiment is the same as the liquid container of the first embodiment except that the filter 72C is disposed in the filter chamber 71 instead of the filter 72 described in the first embodiment. The configuration is almost the same as that of 10A. The liquid container 10C of the third embodiment is attached to the liquid consumption device 500 described in the first embodiment.

  The filter 72C of the third embodiment has a multilayer structure in which two or more members having different pore coarseness through which the liquid passes are stacked. More specifically, the filter 72C has a two-layer structure in which the coarse first filter layer f1 is disposed in the lower layer and the fine second filter layer f2 is disposed in the upper layer.

  According to the liquid container 10C of the third embodiment, foreign substances having various sizes can be efficiently removed by the filter 72C, and occurrence of clogging of the filter 72C can be suppressed. The filter 72C is not limited to a two-layer structure. The filter 72C may be configured such that a plurality of layers are further laminated according to the width of the size of the foreign material assumed to be removed.

  As described above, according to the liquid container 10C of the third embodiment, the performance of removing foreign substances in the liquid is enhanced by the filter 72C having a multilayer structure. In addition, according to the liquid container 10C of the third embodiment, various effects similar to those of the liquid container 10A of the first embodiment can be achieved.

D. Fourth embodiment:
With reference to FIG. 31A and FIG. 31B, the structure of liquid container 10D of 4th Embodiment is demonstrated. FIG. 31A is a schematic perspective view illustrating a configuration of an inner wall portion 65D provided in the storage chamber 31 of the liquid storage container 10D of the fourth embodiment. FIG. 31B is a schematic side view of the inner wall portion 65D provided in the storage chamber 31 of the liquid storage container 10D of the fourth embodiment when viewed in the + X direction. The configuration of the liquid container 10D of the fourth embodiment is the same as that of the first embodiment except that the inner wall 65D having a different arrangement angle is provided instead of the inner wall 65 described in the first embodiment. The configuration is almost the same as that of 10A. The liquid container 10D of the fourth embodiment is attached to the liquid consumption device 500 described in the first embodiment.

  The inner wall portion 65D of the fourth embodiment has substantially the same configuration as the inner wall portion 65 of the first embodiment except that the arrangement angle is different. The inner wall portion 65D is suspended from the upper surface 31u in an inclined state so that the lower end 65e is positioned closer to the second wall portion 22 than the upper end.

  According to the liquid container 10D of the fourth embodiment, even if foreign matter is contained in the liquid to be injected in the liquid injection operation from the liquid inlet 35, the foreign matter is transferred to the second wall by the inner wall portion 65D. It can be guided towards the part 22. Therefore, the foreign matter is prevented from reaching the filter 72, and the occurrence of clogging of the filter 72 is suppressed. In addition, according to the liquid container 10D of the fourth embodiment, various functions and effects similar to those of the liquid container 10A of the first embodiment can be achieved.

E. Fifth embodiment:
With reference to FIG. 32A and FIG. 32B, the structure of the liquid container 10E of 5th Embodiment is demonstrated. FIG. 32A is a schematic perspective view illustrating a configuration of inner wall portions 65a and 65b provided in the storage chamber 31 of the liquid storage container 10E of the fifth embodiment. FIG. 32B is a schematic side view of the inner wall portions 65a and 65b provided in the storage chamber 31 of the liquid storage container 10E of the fifth embodiment when viewed in the + X direction. The configuration of the liquid container 10E according to the fifth embodiment is the same as the liquid container according to the first embodiment except that a pair of inner wall portions 65a and 65b are provided instead of the inner wall portion 65 described in the first embodiment. The configuration is almost the same as that of 10A. The liquid container 10E of the fifth embodiment is attached to the liquid consumption device 500 described in the first embodiment.

  Each of the pair of inner wall portions 65a and 65b of the fifth embodiment has substantially the same configuration as the inner wall portion 65 of the first embodiment except for the points described below. The first inner wall portion 65 a is located on the −Y direction side of the liquid inlet 35, and the second inner wall portion 65 b is located on the + Y direction side of the liquid inlet 35. The first inner wall portion 65a is inclined downward in the direction toward the second inner wall portion 65b. The lower end of the first inner wall portion 65a overlaps with the opening region of the liquid inlet 35 in the Z direction, and is at a position spaced apart from the second inner wall portion 65b in the -Y direction. The lower end of the first inner wall portion 65a is located above the lower end of the second inner wall portion 65b.

  The second inner wall portion 65 b is inclined downward toward the direction away from the second wall portion 22. The lower end of the second inner wall portion 65b is in a position overlapping the opening area of the liquid inlet 35 in the Z direction. The end convex portion 101 provided at the lower end 65e of the second inner wall portion 65b protrudes in the −Y direction. The end convex portion 101 of the second inner wall portion 65b is formed by locally increasing the thickness of the second inner wall portion 65b in the -Y direction.

  In the liquid storage container 10E, the liquid poured from the liquid inlet 35 by the user is guided toward the second inner wall 65b along the surface of the first inner wall 65a on the liquid inlet 35 side, and then the second inner wall 65b. Along the surface on the liquid inlet 35 side, the liquid is transferred to the bottom surface 31b of the storage chamber 31. Thus, the liquid poured from the liquid inlet 35 is injected into the storage chamber 31 while the inflow direction is changed by the two inner wall portions 65a and 65b. Therefore, since the momentum is attenuated in two stages by the two inner wall portions 65a and 65b, foaming of the liquid in the storage chamber 31 is further suppressed.

  In addition, the foreign matter contained in the liquid to be poured can be captured at the upper ends of the end protrusions 101 provided on the two inner wall portions 65a and 65b. Therefore, the foreign matter in the liquid reaches the filter 72 and clogging of the filter 72 is suppressed.

  In the liquid storage container 10 </ b> E, the undulation of the liquid surface due to the liquid poured from the liquid inlet 35 is caused by the second inner wall portion 65 b positioned on the second wall portion 22 side from the liquid inlet 35. Transmission to the liquid level facing the visual recognition unit 38 is suppressed. Accordingly, it is possible to suppress the inaccurate confirmation of the amount of liquid in the storage chamber 31 via the visual recognition unit 38 during the operation of injecting the liquid from the liquid inlet 35.

  In the liquid container 10E, the strength of the open housing member 60 is increased by the two inner wall portions 65a and 65b. Further, the bonding strength of the container lid member 62 to the open housing member 60 is increased. In addition, according to the liquid container 10E of the fifth embodiment, various effects similar to those of the liquid container 10A of the first embodiment can be achieved.

F. Sixth embodiment:
With reference to FIG. 33, the structure of the liquid container 10F of the sixth embodiment will be described.
