Description

  The present invention relates to a liquid container and a liquid ejection system.

  As an embodiment of the liquid container, so-called ink packs are known (for example, Patent Documents 1 to 3 below). The ink pack accommodates ink to be supplied to an ink jet printer (hereinafter, also simply referred to as “printer”) which is an embodiment of the liquid ejecting apparatus in a flexible container. Some printers equipped with ink packs include cases such as trays on which ink packs are arranged. In such a printer, an ink supply path and an electrical communication path between the ink pack and the printer are established by arranging the ink pack in the case and mounting the ink pack together with the case on the printer.

  It is desirable that the ink pack is attached to the printer in an appropriate posture determined in advance. If the mounting posture is not appropriate, there is a possibility that the ink supply path and electrical communication path of the printer cannot be established. In addition, the connection state of the ink supply path and the electrical communication path becomes unstable, and there is a concern that the connection state deteriorates with time. In addition, when connecting to the printer, excessive stress may be generated due to contact with the components on the printer side, resulting in damage or deterioration. Although research has been conducted on improving the mounting posture of the ink pack to the printer, there is still room for improvement. Such a problem is not limited to an ink pack and a printing system including an ink pack and a printer, but is a problem common to a liquid container and a liquid ejecting system including a liquid container and a liquid ejecting apparatus.

  In the fourth surface portion 124 of the connecting member 120a, a linear slit 128 is formed over the entire region in the X direction (FIG. 8). The slit 128 is formed around the center of the connecting member 120a in the Z direction. The accommodating portion 110a is fixed to the connecting member 120a with the outer peripheral end portion 113 on the + Y direction side being inserted into the slit 128 and sandwiched in the thickness direction.

  The connecting member 120a is fitted with a liquid outlet 131, a container-side electrical connecting portion 140, a first receiving portion 150a, a second receiving portion 150b, as components for connecting to the first connection receiving portion 50a. And a combined structure receiving portion 155 (FIGS. 7 and 9A). In the connecting member 120a, those components are grouped on the first surface portion 121 side. Below, after explaining those components in order, the other composition provided in connecting member 120a is explained.

[Liquid outlet]
The liquid outlet 131 is an opening that opens in the + Y direction (FIG. 9A). In the liquid outlet 131, the liquid introduction part 51 (FIG. 5) of the first connection receiving part 50a is inserted in the + Y direction. The liquid outlet 131 is provided at a substantially central position in the X direction on the first surface portion 121. The liquid outlet 131 is formed at substantially the same height as the housing 110a is fixed.

  The liquid outlet 131 is a flow path (not shown) provided inside the connection member 120a, or a flow path member (connected to the fourth surface portion 124 side of the connection member 120a and stored in the storage section 110a). Via the liquid storage area inside the storage section 110a. A detailed description of the configuration of such a liquid channel is omitted. In addition, in order to prevent leakage of liquid, the connection member 120a is kept closed before the liquid introduction part 51 is inserted into the liquid outlet 131, and when the liquid introduction part 51 is inserted. A valve structure or a seal structure is provided (not shown).

  In the present embodiment, the entire peripheral edge 132 of the liquid outlet 131 in the first surface 121 is recessed in the −Y direction, and the liquid outlet 131 is opened at a position recessed in the −Y direction. As a result, the liquid outlet 131 is surrounded by a wall portion formed by the peripheral portion 132, and the protection of the liquid outlet 131 is enhanced. It is suppressed that 131 is touched accidentally. In addition, when the first liquid container 100a is accidentally dropped, deterioration such as damage or deformation due to collision of the liquid outlet 131 is suppressed.

  In the present embodiment, the peripheral edge 132 of the liquid outlet 131 is surrounded by a peripheral rib 133 protruding in the + Y direction. The peripheral rib 133 is pushed in contact with the base end member 57 provided around the liquid introducing portion 51 when the liquid introducing portion 51 of the first connection receiving portion 50a is connected to the liquid outlet 131. Receives elastic force in the -Y direction. When the first liquid container 100a is mounted on the liquid ejecting apparatus 10, the first case 61a in which the first liquid container 100a is disposed is engaged with the first connection receiving portion 50a. (Described later). Therefore, even if the peripheral rib 133 is urged in the −Y direction by the base end member 57, the first liquid container 100a and the first case 61a are prevented from moving in the −Y direction from the arrangement region LA. .

[Container side electrical connection part]
The container-side electrical connection unit 140 includes a substrate unit 141 for connection to the device-side electrical connection unit 52 (FIGS. 9A and 9B). The container-side electrical connection portion 140 is in electrical contact with the device-side electrical connection portion 52 (FIG. 5) of the first connection receiving portion 50a. A plurality of terminal portions 142 are arranged on the surface 141 s of the substrate portion 141. The plurality of terminal portions 142 are arranged at positions corresponding to the terminal portions 52 t of the device-side electrical connection portion 52. A surface of the substrate portion 141 opposite to the surface 141s may be provided with a storage device that stores information about the liquid, a circuit for detecting the connection of the device-side electrical connection portion 52, and the like (illustrated and illustrated). Detailed explanation is omitted).

  In the present embodiment, each terminal portion 142 has a substantially flat contact surface with which the terminal portion 52t of the device-side electrical connection portion 52 contacts. In FIG. 9B, the position of the contact portion CP where the terminal portion 52 t of the device-side electrical connection portion 52 contacts in each terminal portion 142 is illustrated by a broken line. Contact portions CP of each terminal portion 142 are arranged in an arrangement direction parallel to the X direction on each of the upper stage and the lower stage on the surface 141 s of the substrate part 141. In addition, the arrangement pattern of the terminal part 142 and the contact part CP is not limited to that illustrated in FIG. 9B.

  In the present embodiment, the container-side electrical connection portion 140 is provided at a position close to the end portion on the −X direction side of the connection member 120a. In the connection member 120a, a substrate placement portion 144 for placing the substrate portion 141 of the container-side electrical connection portion 140 is formed as a recess recessed in the −Y direction and the + Z direction. The substrate placement portion 144 is formed with an inclined surface 144s that faces in an obliquely upward direction between the + Y direction and the -Z direction, and the container-side electrical connection portion 140 is inclined on the inclined surface 144s. It is inclined and arranged at an arrangement angle substantially parallel to the surface 144s. That is, the normal vector of the contact surface of the surface 141s of the substrate part 141 and the terminal part 52t has a vector component in the + Y direction and a vector component in the -Z direction.

  Thus, the board | substrate part 141 is arrange | positioned so that the surface 141s may face the -Z direction side. Therefore, when the device-side electrical connection portion 52 is electrically connected, the container-side electrical connection portion 140 receives a force in the + Z direction at least downward from the device-side electrical connection portion 52, and the device-side electrical connection portion 52. Will be in electrical contact. Due to the downward force, the contact state between the container-side electrical connection part 140 and the apparatus-side electrical connection part 52 becomes good, and the electrical connectivity of the container-side electrical connection part 140 is improved.

  Moreover, in this embodiment, the board | substrate part 141 is inclinedly arranged as mentioned above, and the surface 141s is suitable also to the + Y direction side. Therefore, when the first liquid container 100a is moved in the + Y direction together with the first case 61a, and the container-side electrical connection part 140 is connected to the apparatus-side electrical connection part 52, the first case 61a is moved in the + Y direction. The electrical connection state between the container-side electrical connection portion 140 and the apparatus-side electrical connection portion 52 can be formed by using the force at the time. Therefore, the electrical connectivity between the container-side electrical connection portion 140 and the device-side electrical connection portion 52 is improved.

  Further, when connecting to the device-side electrical connection portion 52, the terminal portion 52 t of the device-side electrical connection portion 52 moves while rubbing the contact surface of the terminal portion 142 of the container-side electrical connection portion 140. As a result, foreign matter or the like attached to the contact surface of the terminal portion 142 of the container-side electrical connection portion 140 is removed by the terminal portion 52t of the device-side electrical connection portion 52. Is further enhanced.

  In addition, when the first liquid container 100a is taken out from the case housing part 60 together with the first case 61a, the −Y-direction force received from the device-side electrical connection part 52 causes the − of the first liquid container 100a to be − Movement in the Y direction is assisted. Accordingly, the removal of the first liquid container 100a is simplified.

  The substrate unit 141 is installed at a position deep inside the substrate placement unit 144. The board part 141 is sandwiched by two wall parts 145 projecting in the −Z direction and the + Y direction from the surface 141s of the board part 141 on both sides in the X direction. These wall portions 145 function as protection portions for the substrate portion 141. Therefore, for example, it is possible to prevent the user from touching the substrate unit 141 by mistake or from damaging the substrate unit 141 when the first liquid container 100a is accidentally dropped.

[First receiving part and second receiving part]
When the first liquid container 100a is attached to the liquid ejecting apparatus 10, the first receiving portion 150a receives the first positioning portion 53a (FIG. 5) of the first connection receiving portion 50a, and the second receiving portion 150b is The second positioning portion 53b (FIG. 5) is received.

[Second liquid container]
The second liquid container 100b has substantially the same configuration as the first liquid container 100a except for the points described below (FIGS. 14 and 15). In the second liquid container 100b, the width in the X direction is larger than that of the first liquid container 100a so that the amount of liquid that can be stored is larger than that of the first liquid container 100a.

  Similar to the first liquid container 100a, the second liquid container 100b includes a container 110b and a connection member 120b (FIGS. 14 and 15). The container 110b of the second liquid container 100b has substantially the same configuration as the container 110a of the first liquid container 100a, except that the width in the X direction is large.

  The connecting member 120b of the second liquid container 100b has substantially the same configuration as the connecting member 120a of the first liquid container 100a except that a pair of side end support portions 162 are added.

Each side end support portion 162 holds a corner portion on the + Y direction side of the accommodating portion 110b.

  Refer to FIG. The arrangement of the components for connecting to the second connection receiving portion 50b of the connection member 120b of the second liquid container 100b is substantially the same as that of the connection member 120a of the first liquid container 100a. Since the connection member 120b of the second liquid container 100b is small in the change point with respect to the connection member 120a of the first liquid container 100a, the parts can be made common and the manufacturing cost can be reduced. In addition, the second connection receiving portion 50b corresponding to the connection member 120b of the second liquid container 100b can be configured substantially the same as the first connection receiving portion 50a corresponding to the connection member 120a of the first liquid container 100a. The manufacturing cost of the connecting member 120 can be reduced.

  In the following description, when it is not necessary to particularly distinguish between the accommodating part 110a of the first liquid container 100a and the accommodating part 110b of the second liquid container 100b, the accommodating parts 110a and 110b are referred to as “accommodating part 110”. Collectively. Further, when there is no need to particularly distinguish the connection member 120a of the first liquid container 100a and the connection member 120b of the second liquid container 100b, the connection members 120a and 120b are collectively referred to as “connection member 120”.

[Second case]
The second case 61b has substantially the same configuration as the first case 61a except that the second case 61b is modified to fit the width of the second liquid container 100b in the X direction (FIGS. 14, 15 and 15). 16 to 18). At the end of the second case 61b on the + Y direction side, additional wall portions 232 are provided at both ends in the X direction. When the second liquid container 100b is disposed, the additional wall portion 232 faces either one of the pair of side end support portions 162 of the connection member 120b in the Y direction (FIG. 13).

[Mounting mechanism of liquid container]
With reference to FIG. 19, the mounting mechanism of the liquid container 100 with respect to the connection receiving part 50 is demonstrated. The upper part of FIG. 19 illustrates the first liquid container 100a disposed in the first case 61a when viewed in the −Y direction. Further, in the lower part of FIG. 19, a part of the first connection receiving part 50a when viewed in the −Z direction is illustrated so as to correspond to the upper first liquid container 100a. In addition, the following description is common to mounting | wearing of the 1st liquid container 100a with respect to the 1st connection receiving part 50a, and mounting | wearing of the 2nd liquid container 100b with respect to the 2nd connection receiving part 50b.

  In the case storage unit 60 (FIG. 3), when the liquid container 100 is disposed in the case 61 and is moved in the + Y direction toward the arrangement region LA, first, a pair of receiving units 150a of the liquid container 100 is provided. 150b, the pair of positioning portions 53a and 53b of the connection receiving portion 50 are inserted, and the liquid outlet port 131 of the liquid container 100 is positioned.

  Then, the liquid introducing part 51 of the connection receiving unit 50 is inserted into the liquid outlet port 131 of the liquid container 100, and the liquid outlet port 131 of the liquid container 100 and the liquid inlet part 51 of the connection receiving unit 50 are connected. The In addition, before the connection between the liquid outlet 131 and the liquid inlet 51 is completely completed, the peripheral rib 133 provided around the liquid outlet 131 is the base end member 57 around the liquid inlet 51. To touch. When the liquid container 100 and the case 61 are pushed in in the + Y direction until the connection between the liquid outlet 131 and the liquid introduction part 51 is completed, the base end member 57 is displaced in the + Y direction. The liquid container 100 is urged in the −Y direction by an urging member provided inside the base end member 57.

  In parallel with the connection between the liquid outlet 131 and the liquid introduction part 51, the apparatus-side electrical connection part 52 of the connection receiving part 50 is inserted into the substrate placement part 144 of the liquid container 100, and the container-side electrical connection is made. It electrically contacts the substrate part 141 of the part 140. When the connection between the liquid outlet 131 and the liquid introduction part 51 is completed, the electrical connection between the container-side electrical connection part 140 and the apparatus-side electrical connection part 52 is established.

  The device-side fixing structure 54 of the connection receiving portion 50 has a convex portion 210 that constitutes an inlet of the groove portion 215 of the case 61 before the pair of positioning portions 53a and 53b are inserted into the pair of receiving portions 150a and 150b. Are inserted into the internal space 211. When the connection between the liquid outlet 131 and the liquid introduction part 51 is completed, the protrusion part 54p of the apparatus side fixing structure 54 has a case side fixing structure 220 (FIGS. 12 and 18) of the case 61 by an engagement mechanism described later. Engage with the engaged part. Thus, the state in which the position of the case 61 is fixed to the predetermined arrangement area LA (FIG. 3) in the case 61 is the “case storage state in which the case 61 is attached to the case storage portion 60”.

  In the liquid container 100 of the present embodiment, the container-side electrical connection part 140 is located between the liquid outlet 131 and the first receiving part 150a in the X direction. Therefore, the positioning accuracy in the X direction of the container-side electrical connection portion 140 with respect to the device-side electrical connection portion 52 is improved together with the liquid outlet 131 by the pair of positioning portions 53a and 53b and the pair of receiving portions 150a and 150b. .

  Further, in the liquid container 100 of the present embodiment, the concave portion 160 that houses the internal space 211 that is the inlet portion of the case-side fixing structure 220 is between the liquid outlet 131 and the first receiving portion 150a in the X direction. Is located. Therefore, the pair of positioning portions 53a and 53b and the pair of receiving portions 150a and 150b guide the movement of the device-side fixing structure 54 in the Y direction after the device-side fixing structure 54 is inserted into the groove portion 215. The positioning accuracy of the device side fixing structure 54 with respect to the case side fixing structure 220 is improved.

  In addition, in the liquid container 100 of the present embodiment, a pair of the container-side electrical connection portion 140 and the concave portion 160 are provided between the liquid outlet 131 and the first receiving portion 150a as described above. The distance in the X direction between the receiving parts 150a and 150b is large. Therefore, the positioning accuracy described above by the pair of positioning portions 53a and 53b and the pair of receiving portions 150a and 150b is further improved.

As described above, in the liquid container 100 of the present embodiment, the opening shapes of the first opening 151a of the first receiving portion 150a and the second opening 151b of the second receiving portion 150b are different. Opening width _{W 2} is in the X direction of the second opening 151b, it is greater than the opening width _{W 1} in the X direction of the first opening 151a. With this configuration, it is possible to provide a margin in the angle with respect to the Y direction in the horizontal direction of the second positioning portion 53b when the second positioning portion 53b is inserted into the second receiving portion 150b. Therefore, the connection operation of the liquid container 100 with respect to the connection receiving part 50 is facilitated. Further, by providing such a margin, the stress generated when the second positioning portion 53b is inserted into the second receiving portion 150b when the liquid container 100 is connected to the connection receiving portion 50 is reduced. . In the present embodiment, the opening widths in the Z direction of the first opening 151a and the second opening 151b are substantially equal, but the opening widths in the Z direction of the first opening 151a and the second opening 151b are different. Also good.

[Engagement mechanism of device side fixing structure to case side fixing structure]
An engagement mechanism of the device-side fixing structure 54 with respect to the case-side fixing structure 220 of the case 61 will be described with reference to FIGS. 20A and 20B. 20A and 20B each show a case-side fixing structure 220 when viewed in the −Z direction. 20A and 20B, the positions P1 to P6 of the protrusion 54p at different timings are indicated by broken lines in order to show the movement trajectory of the protrusion 54p of the device-side fixing structure 54 in the groove 215.

  First, the configuration of the case side fixing structure 220 will be described with reference to FIG. 20A. The case-side fixing structure 220 has a central convex portion 221 that protrudes in the + Z direction at the center in the region deeper on the −Y direction side than the internal space 211 of the convex portion 210. When viewed in the Z direction, the outer peripheral wall surface of the central convex portion 221 forms a substantially triangular outer peripheral contour line. The inside of the center convex part 221 is thinned.

  The outer peripheral wall surface of the central convex portion 221 includes a first wall surface 222, a second wall surface 223, and a third wall surface 224. The first wall surface 222 extends in an oblique direction between the X direction and the Y direction. At least a part of the first wall surface 222 overlaps the internal space 211 in the Y direction. The second wall surface 223 extends in the X direction and intersects the first wall surface 222. The third wall surface 224 extends in the Y direction and intersects the first wall surface 222 and the second wall surface 223. The third wall surface 224 overlaps the internal space 211 of the convex portion 210 in the Y direction.

  The central convex portion 221 has a first protruding wall portion 225 and a second protruding wall portion 226. The first protruding wall portion 225 is a second portion on the −Y direction side along the direction in which the first wall surface 222 extends from the second wall surface 223 at the −X direction side end of the second wall surface 223. It slightly extends from the wall surface 223. The second protruding wall portion 226 is a wall portion that functions as an engaged portion. Below, the 2nd protrusion wall part 226 may be called the to-be-engaged part 226. FIG. The second protruding wall portion 226 slightly extends from the second wall surface 223 to the −Y direction side along the direction in which the third wall surface 224 extends at the end of the second wall surface 223 on the + X direction side. ing.

  The case side fixing structure 220 further has a third protruding wall portion 227. The third protruding wall portion 227 is formed as a part of the rib 216. The third protruding wall portion 227 protrudes in the + Y direction from the rib 216 toward the second wall surface 223 at a position facing the second wall surface 223 of the central convex portion 221 in the Y direction.

  For convenience of explanation, the groove 215 is divided into a first groove 215a, a second groove 215b, a third groove 215c, and a fourth groove 215d. The first groove portion 215a is a portion that is formed by the internal space 211 and extends in the Y direction. The second groove portion 215b is a portion that faces the first wall surface 222 and extends in an oblique direction between the X direction and the Y direction. The third groove portion 215c includes a portion facing the second wall surface 223, and is a portion formed to meander in a substantially zigzag manner in the X direction by the three protruding wall portions 225 to 227. The fourth groove portion 215d is a portion that faces the third wall surface 224 and extends in the + Y direction toward the first groove portion 215a.

  The first bottom surface 228a that is the bottom surface of the first groove portion 215a constitutes an inclined surface that gradually rises in the + Z direction toward the -Y direction. The second bottom surface 228b, which is the bottom surface of the portion connected to the first groove portion 215a of the second groove portion 215b, constitutes a substantially horizontal horizontal plane. The third bottom surface 228c located around the center of the second groove portion 215b constitutes an inclined surface that falls in the −Z direction from the second bottom surface 228b. The fourth bottom surface 228d including the bottom surface of the end portion of the second groove portion 215b on the −Y direction side and the bottom surface of the third groove portion 215c constitutes a substantially horizontal horizontal plane. The fifth bottom surface 228e, which is the bottom surface of the fourth groove portion 215d, forms an inclined surface that rises in the + Z direction from the fourth bottom surface 228d toward the + Y direction side. A sixth bottom surface 228f, which is a bottom surface between the first bottom surface 228a and the fifth bottom surface 228e, constitutes a substantially horizontal horizontal plane.

  Referring to FIG. 20A, the engagement between the second protruding wall portion 226 (the engaged portion 226) of the case side fixing structure 220 and the protrusion 54p (the engaging portion) of the device side fixing structure 54 is completed. The mechanism up to is explained. When the distal end portion 54t of the device-side fixing structure 54 is inserted in the −Y direction with respect to the first groove portion 215a, the end surface on the + X direction side of the distal end portion 54t becomes the side wall surface 229 on the + X direction side of the first groove portion 215a. In contact with each other, the protrusion 54p of the device-side fixing structure 54 is located at a position away from the side wall surface 229 (P1). At this time, since the end surface of the tip end portion 54t is pushed in the −X direction by the side wall surface 229, the device-side fixing structure 54 rotates more in the −X direction than when no external force is applied in the horizontal direction. It is in the state. In the process of moving in the + Y direction from the position P1, the protrusion 54p of the device-side fixing structure 54 contacts the first bottom surface 228a that is an inclined surface and is pushed in the + Z direction by the first bottom surface 228a.

  When the liquid container 100 is further pushed in the + Y direction, the protrusion 54p of the device side fixing structure 54 is pushed in the + Z direction by the first bottom surface 228a, and the tip end portion 54t of the device side fixing structure 54 is + Z of the rib 216. It is located on the + Z direction side from the end face on the direction side and is separated from the rib 216. Then, the protrusion 54p of the device-side fixing structure 54 contacts the first wall surface 222 and rides on the horizontal second bottom surface 228b (position P2).

  The protrusion 54p of the device-side fixing structure 54 moves to the −Y direction side along the first wall surface 222 while being pushed to the −X direction side by the first wall surface 222, moves down the third bottom surface 228c, and is horizontal. It reaches the third bottom surface 228c and reaches a position where it comes into contact with the first protruding wall portion 225 (position P3). Thereafter, when the protruding portion 54p of the device-side fixing structure 54 is further moved to the −Y direction side and the contact state with the first protruding wall portion 225 is released, the device-side fixing structure 54 is moved toward the + X direction side. Due to the applied urging force, it instantaneously moves to the + X direction side and collides with the third protruding wall portion 227 (position P4). This collision causes a click sound.

  When the user releases the force applied to the liquid container 100 and the case 61 in the + Y direction by the click sound, the liquid container is energized by the biasing force in the + Y direction by the base end member 57 (FIG. 19). 100 and the case 61 move slightly in the + Y direction. As a result, the protrusion 54p of the device-side fixing structure 54 moves in the + Y direction along the third protrusion wall 227, and the contact state of the protrusion 54p with the third protrusion wall 227 is released. Then, the protrusion 54p instantaneously moves to the + X direction side by the biasing force applied to the device side fixing structure 54 toward the + X direction side, and collides with the second wall surface 223 and the second protruding wall portion 226. (Position P5).

  Thus, at the position P5, the protrusion 54p of the device side fixing structure 54 is locked to the second protruding wall portion 226 of the case side fixing structure 220, and the second protruding wall portion 226 of the case side fixing structure 220 and the device side The protrusion 54p of the fixing structure 54 is engaged. Below, the 2nd protrusion wall part 226 may be called the "locking part 226" other than the to-be-engaged part 226. Due to the engagement between the second protruding wall portion 226 of the case side fixing structure 220 and the protrusion 54p of the device side fixing structure 54, the movement of the case 61 in the -Y direction is restricted, and the case 61 is stored in the case. The case attached to the portion 60 is in the stored state. In this state, the protrusion 54p of the device-side fixing structure 54 is in contact with the fourth bottom surface 228d. As described above, the device-side fixing structure 54 is biased in the −Z direction by an elastic member (not shown) disposed inside the connection receiving portion 50, and receives an external force in the + Z direction. It rotates elastically in the + Z direction. This urging force in the + Z direction is transmitted to the fourth bottom surface 228d (FIG. 20A) through the protrusion 54p. That is, in the case storage state in which the case 61 is attached to the case storage portion 60, the protrusion 54p is in a state in which a force is applied to the case 61 in the -Z direction.

  Here, in the case storage state in which the engaged portion 226 of the case side fixing structure 220 and the engaging portion 54p of the device side fixing structure 54 are engaged, the container side electrical connection portion 140 is The container-side electrical connection portion 140 is electrically connected to the side electrical connection portion 52 and is in a state of receiving at least a force in the + Z direction from the device-side electrical connection portion 52. If it is the liquid container 100 of this embodiment, as above-mentioned, the recessed part 160 and the container side electrical connection part 140 have the positional relationship in which at least one part overlaps when it sees to a Z direction. The convex portion 210 of the case 61 is accommodated in the concave portion 160. The internal space 211 of the convex part 210 constitutes at least a part of the case-side fixing structure 220. At least part of the force in the + Z direction received by the container-side electrical connection portion 140 from the device-side electrical connection portion 52 is canceled by the force received by the case 61 in the −Z direction from the protrusion 54p. Therefore, the component in the Z direction of the force received by the liquid container 100 on the + Y direction side is reduced, and the arrangement posture of the liquid container 100 in the Z direction is suppressed from deviating from the assumed proper posture. . Therefore, the deterioration of the arrangement posture of the liquid container 100 with respect to the connection receiving unit 50 is suppressed, and the connection state is improved. Further, it is possible to suppress unnecessary stress from being generated at the connection portion between the connection receiving unit 50 and the liquid container 100 as the arrangement posture of the liquid container 100 is lowered. Damage and deterioration of the various components described above for connecting the body 100 are suppressed.

  With reference to FIG. 20B, a mechanism for releasing the engagement state between the case-side fixing structure 220 and the apparatus-side fixing structure 54 will be described. In the liquid ejecting apparatus 10 of the present embodiment, as described below, the case 61 is further pushed in the + Y direction when the case side fixing structure 220 and the apparatus side fixing structure 54 are in the above-described engaged state. When engaged, the engagement state is released. When the user pushes the case 61 in the + Y direction, the protrusion 54p of the device-side fixing structure 54 moves in the + Y direction from the position P5, and deviates from the state of being engaged with the second protruding wall portion 226 in the + X direction. Therefore, due to the urging force applied to the device-side fixing structure 54 toward the + X direction side by the urging member, the protrusion 54p instantaneously moves to the + X direction side, and the side wall surface 229 of the rib 216 on the + X direction side. (Position P6).

  As a result, the protrusion 54p is positioned in the fourth groove 215d, so that the movement in the + Y direction is allowed. That is, the engagement state between the case-side fixing structure 220 and the apparatus-side fixing structure 54 is released. The user can know that the engagement state between the case-side fixing structure 220 and the apparatus-side fixing structure 54 has been released by the click sound generated by the collision of the protruding portion 54p with the rib 216 described above. When the protrusion 54p is allowed to move in the + Y direction, the liquid container 100 and the case 61 are automatically moved in the -Y direction by the force applied in the + Y direction by the base end member 57 (FIG. 13). . After the base end member 57 is separated from the connection receiving portion 50, the liquid container 100 can be taken out by the user pulling out the case 61. As can be seen from the above description, the groove portion 215 constitutes a loop-shaped guide path that guides the protruding portion 54p. The entrance portion and the exit portion of the guide path are common. The guide path is configured by a locking portion 226 that locks the protruding portion 54p provided in the middle, an inlet side guide path, and an outlet side guide path. The entrance side guide path is a path portion from the entrance portion described above to the locking portion 226. The exit side guide path is a path portion from the locking portion 226 to the exit portion described above.

[Packaging of liquid container]
21A and 21B are schematic views for explaining a method of packing the liquid container 100. FIG. The liquid container 100 is desirably packaged as follows at a stage before being attached to the case 61 of the liquid ejecting apparatus 10 such as when shipped from a factory. In the first step, the entire liquid container 100 is housed in a packaging material 300 in which a flexible film member is formed in a bag shape and hermetically sealed (FIG. 21A).

It is desirable that the packaging material 300 is made of a material having good gas barrier properties. The packing material 300 preferably has a gas permeability of less than 1.0 [cc / (m ² · day · atm)], and is 0.5 [cc / (m ² · day · atm)] or less. It is more desirable. Further, the gas permeability of the packaging material 300 is more preferably 0.1 [cc / (m ² · day · atm)] or less. The gas permeability may be a value measured by the isobaric method. The isobaric method is a method in which an inert gas is sealed at the same pressure in two indoor spaces separated by a diaphragm formed of a sample, and then a test gas is injected into one of the indoor spaces. Is a method of measuring the speed of passing through the sample and moving to the other indoor space. The packaging material 300 is comprised by aluminum foil, a silica vapor deposition film, and an aluminum vapor deposition film, for example. In consideration of gas barrier properties, an aluminum foil, a silica deposited film, and an aluminum deposited film are preferable in this order.

  The packing material 300 is previously provided with an air suction port 301 that communicates with the internal space. In the second step, a suction pump 310 is connected to the air suction port 301 to decompress the internal space of the packaging material 300. In this step, it is desirable that the pressure is reduced to such an extent that the packing material 300 is in close contact with the entire liquid container 100 (FIG. 21B).

  If the internal space of the packaging material 300 is depressurized, the air present in the storage unit 110 of the liquid container 100 can be guided to the outside of the storage unit 110, and the liquid stored in the storage unit 110 can be guided. Durability can be increased. Moreover, since the accommodating part 110 will be in the state tightly wrapped by the packing material 300, a deformation | transformation of the accommodating part 110 which has flexibility is suppressed. Therefore, a decrease in the stability of the liquid in the storage unit 110 is suppressed, for example, the liquid in the storage unit 110 swings due to the deformation of the storage unit 110. In addition, the handling property of the liquid container 100 is improved by suppressing the deformation of the container 110.

  Instead of performing the pressure reducing process by the suction pump 310 in the second process, the liquid container 100 may be wrapped with the packaging material 300 so that the liquid container 100 is tightly tightened in the first process. . Even with such a method, the deformation of the container 110 can be easily suppressed by the packing material 300, and the protection of the liquid and the handling of the liquid container 100 are improved.

[Summary of First Embodiment]
As described above, according to the liquid container 100 of the present embodiment, at least one of the forces in the Z direction that the container-side electrical connecting portion 140 receives from the device-side electrical connecting portion 52 in a state where the container is attached to the liquid ejecting apparatus 10. The portion is reduced by the force that the case 61 receives from the protrusion 54p of the device-side fixing structure 54, that is, the engaging portion 54p. Therefore, it is suppressed that the arrangement posture of the liquid container 100 is shifted from the proper posture in the Z direction. Further, since the width in the Z direction of the liquid container 100 is smaller than the width in the X direction and the width in the Y direction of the liquid container 100, the arrangement posture of the liquid container 100 on the case 61 is stabilized. Accordingly, the connection state of the liquid container 100 to the liquid ejecting apparatus 10 is improved.
