The liquid storage part 32 is a flexible bag and is filled with liquid. The internal space 399 that stores the liquid in the liquid storage portion 32 is partitioned by a sheet member (film member) 301. As the liquid stored in the liquid storage unit 32 is consumed, the volume of the liquid storage unit 32 gradually decreases. The liquid storage part 32 communicates with the liquid supply part 42 of the connection body 40. When the liquid in the liquid storage unit 32 is consumed and the remaining amount becomes zero or almost disappears, the liquid storage body 35 is newly replaced.

  The connection body 40 (FIG. 6) can be attached to and detached from the mounting portion 20. The connection body 40 includes a liquid supply section 42, a pair of regulating sections 47 (only one is shown in the figure), a circuit board 443, a liquid injection section 461, a supply flow path 480, and an injection flow path 482.

Details of the pair of restricting portions 47 will be described later.

  The liquid injection part 461 is a cylindrical member that extends along the Y-axis direction. The liquid injection part 461 forms a part of the injection channel 482 that merges with the supply channel 480. The injection channel 482 is a channel through which an external liquid flows toward the liquid storage unit 32. By injecting the liquid from the liquid injection part 461, the liquid can be injected into the liquid storage part 32 through the injection flow path 482. In the liquid flow direction (injection flow direction) from the liquid injection part 461 to the liquid storage part 32, the downstream side of the injection flow path 482 merges with the supply flow path 480.

  The connection body 40 (FIG. 6) includes a supply member 49 whose one end 492 side is attached to the liquid storage portion 32, and a connection main body member 43 attached to the other end 493 side of the supply member 49.

  The storage box 31 (FIG. 5) stores the liquid storage portion 32. The outer shape of the storage box 31 is a substantially rectangular parallelepiped shape. In the present embodiment, the storage box 31 is formed of cardboard. The storage box 31 is made of a material mainly composed of cellulose, for example. In other embodiments, the storage box 31 may be formed of another member (for example, a synthetic resin such as polypropylene or polyethylene). The storage box 31 includes a storage box first surface (storage box first wall) 311, a storage box second surface (storage box second wall) 312, a storage box third surface (storage box third wall) 313, A storage box fourth surface (storage box fourth wall) 314, a storage box fifth surface (storage box fifth wall) 315, and a storage box sixth surface (storage box sixth wall) 316 are provided.

  In the mounted state of the liquid storage container 30, the storage box first surface 311 forms an upper surface, and the storage box second surface 312 forms a bottom surface. The storage box third surface 313 forms one side surface, and the storage box fourth surface 314 forms the other side surface. The container box fifth surface 315 forms a front surface facing the mounting portion 20, and the container box sixth surface 316 forms a rear surface. The container box first surface 311 and the container box second surface 312 face each other in the Z-axis direction. The storage box third surface 313 and the storage box fourth surface 314 face each other in the X-axis direction. The container box fifth surface 315 and the container box sixth surface 316 face each other in the Y-axis direction.

  The connecting body 40 (FIG. 4) is inserted through the storage box fifth surface 315 in the extracted state. Thereby, a part of the connection body 40 is exposed to the outside of the storage box 31. When the liquid storage container 30 is not used, such as when it is transported, the entire connection body 40 is stored inside the storage box 31. For example, the connection body 40 is accommodated in the accommodation box 31 by opening the opening / closing part 331.

  The storage box fifth wall 315 (FIG. 5) has an extraction opening 350 as an opening through which the liquid supply unit 42 can be extracted from the storage box 31 in a state where the liquid storage unit 32 is stored inside the storage box 31. Is formed. The extraction opening 350 penetrates the storage box fifth wall 315 in the Y-axis direction. The extraction opening 350 has an insertion opening 332 and an opening / closing opening 335 formed by opening the opening / closing part 331. The extraction opening 350 is not limited to the formation position of the present embodiment, and may be formed on another wall of the storage box 31. Further, the shape and size of the insertion opening 332 and the opening / closing part 331 are not limited to the present embodiment.

  The insertion opening 332 is a part through which the connection body 40 is inserted in the extracted state. The insertion opening 332 is formed by removing a part of the storage box fifth wall 315 along the cut line formed in the storage box fifth wall 315 that the liquid storage container 30 has at the time of product shipment. The insertion opening 332 has a first support surface 334A and a second support surface 334B that define the insertion opening 332. The first support surface 334A and the second support surface 334B are surfaces facing the antigravity direction (upward direction) in the mounted state. That is, the direction of the normal vector of the first support surface 334A and the second support surface 334B is the antigravity direction. In the removed state, the restricting portion 47 (FIG. 4) abuts on the first support surface 334A and the second support surface 334B. Thus, the first support surface 334A and the second support surface 334B support the restricting portion 47 from below in the extracted state. When the first support surface 334A and the second support surface 334B are used without being distinguished from each other, they are called “support surfaces 334”. The insertion opening 332 may be in an open state at the time of product shipment.

  The opening / closing part 331 is located on the upper side (anti-gravity direction side) of the insertion opening 332 in the mounted state. The opening / closing part 331 is a plate-like member configured to be opened and closed with the upper side 330 as a fulcrum. The opening / closing part 331 includes an upper side 330 in which a fold is formed, and other sides 337 that are located at both ends of the upper side 330 and are separated from the storage box fifth wall 315. The other side 337 is formed with a cut for easy separation. In FIG. 5, the other side 337 is indicated by a dotted line. When the liquid supply part 42 is taken out from the inside of the storage box 31, the opening / closing opening part 335 is caused to appear by opening the opening / closing part 331 outward of the storage box 31 with the upper side 330 as a fulcrum. Thereby, the liquid supply part 42 is taken out of the storage box 31 in a state where the opening area of the take-out opening part 350 is increased. After the liquid supply part 42 is taken out, the opening / closing part 331 is closed and constitutes a part of the storage box fifth wall 315. In the state where the liquid storage unit 32 is stored in the storage box 31, the extraction direction when the liquid supply unit 42 is extracted from the storage box 31 to the outside via the extraction opening 350 is substantially the + Y-axis direction. The storage direction when the liquid supply unit 42 is stored from the outside of the storage box 31 through the take-out opening 350 in the state where the liquid storage unit 32 is stored in the storage box 31 is approximately the −Y axis direction. Become. As described above, the storage box fifth wall 315 has the extraction opening 350 for taking out the liquid supply part 42 from the inside of the storage box 31 in a state where the liquid storage part 32 is stored in the storage box 31. ing. Therefore, the storage box fifth wall 315 is also referred to as an extraction opening forming wall 315.

  The storage box 31 (FIG. 5) further includes gripping openings 321 and 322 formed on the first surface 311 of the storage box for gripping. Each of the holding openings 321 and 322 has an oval shape that is long in the width direction (X-axis direction). The user can easily carry the liquid container 30 by inserting and grasping the hand into the grip openings 321 and 322. The holding openings 321 and 322 are not limited to the storage box first surface 311 and may be formed on other surfaces (for example, the storage box fifth surface 315 and the storage box sixth surface 316).

  FIG. 7 is a first perspective view of the connection main body member 43. FIG. 8 is a second perspective view of the connection main body member 43.

  The connection main body member 43 (FIG. 7) includes an intermediate member 48 and a connection member 41. The intermediate member 48 and the connection member 41 are each formed of a synthetic resin. In the present embodiment, the intermediate member 48 and the connection member 41 are each formed of a material mainly composed of polypropylene (PP).

  The external shape of the connection member 41 is a substantially rectangular parallelepiped shape. The connecting member 41 includes a first surface (first wall) 411, a second surface (second wall) 412, a third surface (third wall) 413, a fourth surface (fourth wall) 414, It has a fifth surface (fifth wall) 415 and a sixth surface (sixth wall) 416.

  In the mounted state, the first surface 411 forms an end surface (upper surface) on the + Z-axis direction side. In the mounted state, the second surface 412 forms an end surface (bottom surface) on the −Z axis direction side. In the mounted state, the third surface 413 forms an end surface (one side surface) on the −X axis direction side. In the mounted state, the fourth surface 414 forms an end surface (other side surface) on the + X axis direction side. In the mounted state, the fifth surface 415 forms an end surface (front surface) on the + Y axis direction side. In the mounted state, the sixth surface 416 forms an end surface (back surface) on the −Y axis direction side. The first surface 411 and the second surface 412 are portions facing the inner peripheral surface forming the accommodation space 21A of the mounting portion 20 in the Z-axis direction. The third surface 413 and the fourth surface 414 are portions facing the inner peripheral surface forming the accommodation space 21A of the mounting portion 20 in the X-axis direction.

  The connection member 41 includes a liquid supply part 42 that protrudes from the fifth surface 415. The base end part 42e of the liquid supply part 42 is connected to the connection member 41, and the liquid outlet 480B as the tip part opens toward the outside. The axial direction of the central axis 42CT is in a horizontal state, and in the extraction state, the direction from the base end portion 42e toward the liquid outlet 480B (+ Y-axis direction) is the extraction direction of the liquid supply unit 42. The state in which the axial direction of the central shaft 42CT is horizontal means that the axial direction is slightly inclined with respect to the horizontal direction due to a completely horizontal state and a slight inclination of the installation surface of the liquid container 30 and the like. Including state. Further, the axial direction of the central shaft 42CT is in a horizontal state, and in the extracted state, the direction from the liquid outlet 480B toward the base end portion 42e (the −Y-axis direction) is the storage direction of the liquid supply unit 42.

  Further, the connection member 41 has an injection channel 482 including a liquid injection part 461. A circuit board 443 is disposed on the anti-gravity direction side (upper side) of the liquid supply unit 42 and the liquid injection unit 461 in the connection member 41.

  Inside the liquid supply part 42 and the liquid injection part 461, a valve mechanism (not shown) for suppressing the leakage of the liquid to the outside is arranged. The valve mechanism disposed in the liquid supply unit 42 is opened when the liquid introduction needle 223 (FIG. 3) is inserted into the liquid supply unit 42, and the liquid is supplied to the liquid introduction needle 223 via the supply channel 480. Distributed.

  The intermediate member 48 is attached to the sixth surface 416 of the connection member 41 by welding or the like. The intermediate member 48 has an intermediate opening 485 (FIG. 8) that forms a part of the supply channel 480 inside. The intermediate opening 485 is formed by an intermediate main body 488 that forms the main body of the intermediate member 48. Further, the intermediate member 48 has two restricting portions 47. The two restricting portions 47 are connected to the intermediate main body portion 488. When the two restricting portions 47 are distinguished from each other, they are referred to as “first restricting portion 47A” and “second restricting portion 47B”. The first restricting portion 47A and the second restricting portion 47B are in a state in which the axial direction along the central axis 42CT is horizontal and intersects the axial direction and the gravitational direction when in the removed state (this embodiment) In the embodiment, the liquid supply unit 42 is disposed at a position sandwiching the liquid supply unit 42 in the X-axis direction as an orthogonal direction. The regulation member 47 is connected to the liquid supply unit 42 by attaching the intermediate member 48 and the connection member 41 to each other. That is, the restricting portion 47 and the liquid supply portion 42 constitute the connection main body member 43 and are interlocked with each other.

  FIG. 9 is a partially enlarged view of FIG. FIG. 10 is a diagram for explaining the restricting portion 47 in the removed state. In FIG. 10, the inner facing wall 472 in the no-load state (the state before the extraction state) is indicated by a dotted line. 47 A of 1st control parts and the 2nd control part 47B differ in an arrangement position, but others have the same structure. Therefore, hereinafter, the configuration will be described as the restricting portion 47 without distinguishing the first restricting portion 47A and the second restricting portion 47B.

  The restricting portion 47 (FIG. 9) includes an inner facing wall 472, an outer facing wall 471, a connection wall 473, and a receiving opening 478. Each wall 471,472,473 is a plate-shaped member.

  The internal facing wall 472 (FIG. 10) opposes the inner surface 315fb, which is the inner side of the storage box 31, in the extraction opening forming wall 315 in the extraction state. The internal facing wall 472 (FIG. 9) has a first base end 472t that is one end and a first tip 472p that is the other end. In the extracted state, the first base end portion 472t is located above the first tip end portion 472p. The first base end portion 472t is connected to the connection wall 473. The inner facing wall 472 extends in a direction intersecting with the axial direction along the central axis 42CT. In the present embodiment, in the extracted state, the internal facing wall 472 extends from the connection wall 473 toward the lower side (gravity direction side).

  The internal facing wall 472 includes a bent portion 474, a flat plate portion 475, and a tapered portion 476 in order from the first base end portion 472t toward the first tip end portion 472p. The bent portion 474 includes a first base end portion 472 t and connects the connection wall 473 and the flat plate portion 475. The bent portion 474 is curved so that a connection portion (first base end portion 472t) with the connection wall 473 is smooth without forming a corner. Thereby, even when the internal facing wall 472 is elastically deformed as described later with the first base end portion 472t as a fulcrum, it is possible to suppress stress from being concentrated on the first base end portion 472t.

  The flat plate portion 475 connects the bent portion 474 and the tapered portion 476. The flat plate portion 475 is inclined so as to approach the external facing wall 471 from the first base end portion 472t side toward the first tip end portion 472p side in a no-load state where no external force is applied. The tapered portion 476 includes a first tip portion 472p. The taper portion 476 is inclined so as to move away from the outer facing wall 471 as it goes from the first base end portion 472t side to the first tip end portion 472p side in a no-load state. That is, the distance between the tapered portion 476 and the outer facing wall 471 in the Y-axis direction becomes smaller as it goes from the first distal end portion 472p defining the receiving opening 478 toward the first proximal end portion 472t. As a result, when the restricting portion 47 is placed on the inner facing wall 472 to be in the take-out state, the take-out opening forming wall 315 can be easily inserted into the receiving opening 478.

  The outer facing wall 471 faces the inner facing wall 472 in the axial direction (Y-axis direction). The outer facing wall 471 (FIG. 10) faces the outer surface 315fa on the outer side of the storage box 31 in the extraction opening forming wall 315 in the extraction state. The external facing wall 471 (FIG. 9) has a second base end 471t that is one end and a second tip 471p that is the other end. In the extracted state, the second base end portion 471t is positioned above the second tip end portion 471p. The second base end portion 471t is connected to the connection wall 473.

  The outer facing wall 471 extends in a direction intersecting the axial direction along the central axis 42CT. In the present embodiment liquid, the external facing wall 471 extends from the connection wall 473 along the direction of gravity in the extracted state. That is, the external facing wall 471 is a wall substantially perpendicular to the axial direction. A plurality of ribs 479 are formed on the surface of the outer facing wall 471 opposite to the side facing the inner facing wall 472. The rib 479 extends along the X-axis direction. Adjacent ribs 479 are arranged at an interval in the Z-axis direction. Since the outer facing wall 471 includes the ribs 479, the outer facing wall 471 has higher rigidity than the inner facing wall 472. Note that the outer facing wall 471 may be configured to have higher rigidity than the inner facing wall 472 by other configurations. For example, the rigidity of the outer facing wall 471 may be increased by making the thickness of the outer facing wall 471 larger than the thickness of the inner facing wall 472. Further, for example, by providing ribs or increasing the thickness, a part of the outer facing wall 471 is formed so as to be more rigid than the inner facing wall 472, so that the entire outer facing wall 471 is formed. May be higher than the rigidity of the internal facing wall 472.

  The connection wall 473 connects the first base end portion 472t and the second base end portion 471t. The connection wall 473 is a horizontal wall in the extracted state. The connection wall 473 (FIG. 10) has an abutting portion 473fa that abuts on the support surface 334 of the extraction opening forming wall 315 in the extraction state. The contact portion 473fa is in a state where the axial direction is horizontal, and is located on the upper side (antigravity direction side) of the central axis 42CT of the liquid supply portion 42 in the extracted state. Compared with the case where the contact portion 473fa is located on the gravity direction side of the central axis 42CT, the liquid in the liquid storage portion 32 can be smoothly circulated to the liquid supply portion 42. In the extracted state, the portion of the connecting member 41 that is located on the antigravity direction side of the restricting portion 47 (specifically, the contact portion 473fa) faces the insertion opening 332, and the restricting portion 47 (specifically, A portion located on the gravity direction side of the contact portion 473fa) faces the extraction opening forming wall 315 (FIG. 4). Therefore, in the extracted state, the portion of the connecting member 41 that is located on the antigravity direction side of the restricting portion 47 (specifically, the contact portion 473fa) is in the direction including the Y-axis direction component with the contact portion 473fa as a fulcrum. There is a possibility of displacement. On the other hand, in the extracted state, the portion of the connecting member 41 that is located on the gravity direction side of the restricting portion 47 (specifically, the contact portion 473fa) can suppress displacement by the extraction opening forming wall 315. That is, the contact portion 473fa is positioned on the antigravity direction side of the central axis 42CT of the liquid supply unit 42, so that the liquid supply unit 42 can be further suppressed from moving in the extraction state.

  The receiving opening 478 (FIG. 9) is defined by the first tip 472p and the second tip 471p. The receiving opening 478 forms an opening through which the extraction opening forming wall 315 is inserted. The receiving opening 478 faces the connection wall 473. In the state where the axial direction is horizontal and in the extracted state, the receiving opening 478 opens in the direction of gravity. In other words, when the restricting portion 47 is placed on the fifth storage wall 315 and is in the removal state, the receiving opening 478 is moved in the direction of gravity, so that the receiving opening 478 is positioned on the side of the gravity direction. Accept 5 walls 315.

  The internal facing wall 472 (FIG. 10) is configured to be elastically deformable in a direction RD including the axial direction (Y-axis direction) with the first base end 472t as a fulcrum. In a no-load state where no external force is applied to the restricting portion 47, the distance Lp between the inner facing wall 472 and the outer facing wall 471 is smaller than the thickness L315 of the extraction opening forming wall 315. The distance Lp means the minimum distance between the inner facing wall 472 and the outer facing wall 471 in the Y-axis direction. When the liquid supply part 42 is changed from the state before the extraction to the extraction state, the extraction opening forming wall 315 is inserted into the receiving opening 478 and the extraction opening forming wall is interposed between the outer facing wall 471 and the inner facing wall 472. 315 is arranged. In the process of inserting the extraction opening forming wall 315 through the receiving opening 478, the internal opening wall 472 is elastically deformed by the extraction opening forming wall 315 in the direction away from the external facing wall 471 with the first base end 472t as a fulcrum. Thereby, the space | interval of the external opposing wall 471 and the internal opposing wall 472 becomes large. In addition, since the internal facing wall 472 is elastically deformed, the extraction opening forming wall 315 can be easily sandwiched between the internal facing wall 472 and the external facing wall 471 in the removed state. Since the extraction opening forming wall 315 is sandwiched between the inner facing wall 472 and the outer facing wall 471, the position of the liquid supply part 42 in the extracted state can be stably fixed. In addition, since the outer facing wall 471 has higher rigidity than the inner facing wall 472, the outer facing wall 471 can be prevented from being deformed in the extracted state. Thereby, the position of the liquid supply part 42 in the taken-out state can be more stably fixed.

  According to the first embodiment, since the movement of the liquid supply part 42 in the axial direction can be restricted by the restriction part 47 having the inner facing wall 472 and the outer facing wall 471, the position of the liquid supply part 42 in the taken-out state is easy. Can be fixed. Further, according to the first embodiment, since the restricting portion 47 has the receiving opening 478, when the liquid storage container 30 is taken out, the receiving opening forming wall 315 is inserted through the receiving opening 478. The extraction opening forming wall 315 can be easily disposed between the inner facing wall 472 and the outer facing wall 471. In particular, in the first embodiment, the receiving opening 478 opens in the direction of gravity. Accordingly, when the liquid storage container 30 is taken out, the take-out opening forming wall 315 can be easily disposed between the inner facing wall 472 and the outer facing wall 471 by moving the restricting portion 47 in the direction of gravity. .

  Further, according to the first embodiment, since the movement of the liquid supply part 42 can be restricted by the two restriction parts 47A and 47B, the possibility that the liquid supply part 42 moves along the axial direction in the removed state can be further reduced. Therefore, the position of the liquid supply part 42 in the extracted state can be more stably fixed.

B. Second embodiment:
FIG. 11 is a perspective view of the liquid container 30a of the second embodiment. FIG. 12 is a perspective view of the storage box 31a. The difference between the liquid storage container 30a of the second embodiment and the liquid storage container 30a of the first embodiment is the shape of the extraction opening 350a of the extraction opening forming wall 315a and the shape of the regulation portion 47a of the connection body 40a. . Since other configurations are the same as those in the first embodiment, the same configurations are denoted by the same reference numerals and the description thereof is omitted.

  Similarly to the liquid container 30a (FIG. 4) of the first embodiment, each of the two restricting portions 47a (only one is shown in FIG. 11) is taken out of the liquid container 30a (FIG. 11). It is located so as to face the inner surface and the outer surface of the opening forming wall 315a. Thereby, in the extraction state, the movement of the liquid supply part 42 in the axial direction (Y-axis direction) along the central axis 42CT of the liquid supply part 42 is restricted by the two restriction parts 47a.

  The extraction opening 350a (FIG. 12) of the storage box 31a has an insertion opening 332a. The insertion opening 332a is a part through which the connection body 40a is inserted in the extracted state. The insertion opening 332a has a larger dimension in the Z-axis direction of the side surface 351 than the insertion opening 332 of the first embodiment. The side surface 351 defines the insertion opening 332a. One of the two side surfaces 351 is also called a first side surface 351A, and the other is also called a second side surface 351B. The restricting portion 47a is disposed so as to sandwich a portion including the side surface 351 of the insertion opening 332a in the extraction opening forming wall 315a. Details of this will be described later.

  FIG. 13 is a first perspective view of a connection main body member 43a included in the connection body 40a. FIG. 14 is a second perspective view of the connection main body member 43a. FIG. 15 is a view for explaining the restricting portion 47a in the removed state.

  The intermediate member 48a (FIG. 14) constituting the connection main body member 43a has two restricting portions 47a. The two restricting portions 47 a are connected to the intermediate main body portion 488. When the two restricting portions 47a are used separately, they are referred to as “first restricting portion 47Aa” and “second restricting portion 47Ba”. The first restricting portion 47Aa and the second restricting portion 47Ba differ in the arrangement position and the opening direction of the receiving opening 478a, but have the same configuration. Therefore, in the following, regarding the same configuration, the configuration will be described as the restricting portion 47a without distinguishing the first restricting portion 47Aa and the second restricting portion 47Ba.

  The restricting portion 47a (FIG. 14) includes an inner facing wall 472a, an outer facing wall 471a, a connection wall 473a, and a receiving opening 478a. Each wall 471a, 472a, 473a is a plate-like member.

  The inner facing wall 472a (FIG. 15) faces the inner surface 315fb, which is the inner side of the storage box 31, in the extraction opening forming wall 315a in the extracted state. The internal facing wall 472a (FIG. 14) has a first base end 472t that is one end and a first tip 472p that is the other end. The first base end portion 472t is connected to the connection wall 473a. The inner facing wall 472a extends in a direction that intersects the axial direction along the central axis 42CT. In the present embodiment, the inner facing wall 472a extends from the connection wall 473a toward the outer side in the width direction of the connection body 40a. Specifically, the inner facing wall 472a of the first restricting portion 47Aa extends from the connection wall 473a toward the −X axis direction side, which is the outer side in the width direction. Further, the inner facing wall 472a of the second restricting portion 47Ba extends from the connection wall 473a toward the + X axis direction side that is the outer side in the width direction.

  The outer facing wall 471a faces the inner facing wall 472a in the axial direction (Y-axis direction). The outer facing wall 471a (FIG. 15) faces the outer surface 315fa, which is the outer side of the storage box 31a, of the extraction opening forming wall 315a in the extracted state. The external facing wall 471a (FIG. 14) has a second base end portion 471t that is one end portion and a second tip end portion 471p that is the other end portion. The second base end portion 471t is connected to the connection wall 473a. The outer facing wall 471a extends in a direction intersecting the axial direction along the central axis 42CT. In the present embodiment, the external facing wall 471a extends from the connection wall 473a toward the outside in the width direction of the connection body 40a. Specifically, the outer facing wall 471a of the first restricting portion 47Aa extends from the connection wall 473a toward the −X axis direction side, which is the outer side in the width direction. Further, the inner facing wall 472a of the second restricting portion 47Ba extends from the connection wall 473a toward the + X axis direction side that is the outer side in the width direction.

  The connection wall 473a (FIG. 14) connects the first base end portion 472t and the second base end portion 471t. The connection wall 473a is a vertical wall in the extracted state, and faces the side surface 351 (FIG. 12).

  The receiving opening 478a (FIG. 14) is defined by the first tip 472p and the second tip 471p. The receiving opening 478 forms an opening through which the extraction opening forming wall 315a is inserted. The receiving opening 478a faces the connection wall 473a. In the state where the axial direction is horizontal and in the extracted state, the receiving opening 478a is in the horizontal direction and is orthogonal to the axial direction (in this embodiment, the direction facing the outside in the width direction of the connecting body 40a). ). Further, in the state where the axial direction is horizontal and in the taken-out state, the receiving opening 478a opens in the direction of gravity. That is, when the restricting portion 47a is placed on the extraction opening forming wall 315a to be in the extraction state, the extraction opening forming wall 315a is inserted into the receiving opening 478 so that the extraction opening forming wall 315a is externally facing the wall 471a. And the inner facing wall 472a (FIG. 15).

  According to the said 2nd Embodiment, there exists the same effect in the point which has the structure similar to the said 1st Embodiment. For example, the liquid container 30a restricts the movement of the liquid supply part 42 in the axial direction by the restriction part 47a having the inner facing wall 472a and the outer facing wall 471a. Can be fixed. In addition, according to the second embodiment, in the state where the axial direction is horizontal and in the taken-out state, the receiving opening 478a opens in the horizontal direction and in a direction perpendicular to the axial direction. Thus, when the liquid container 30a is taken out, the take-out opening forming wall 315a is inserted into the receiving opening 478a so that the take-out opening forming wall 315a is interposed between the inner facing wall 472a and the outer facing wall 471a. Easy to place.

C. Other embodiments of the liquid storage part 32:
The liquid storage part 32 of the said 1st Embodiment and 2nd Embodiment should just be the structure which can accommodate a liquid. Hereinafter, another preferred embodiment of the liquid storage unit 32 will be described.

C-1. First alternative embodiment for the liquid container:
FIG. 16 is a schematic diagram for explaining the first other embodiment. The liquid storage portion 32a is a flexible gusset bag. The liquid storage portion 32a is formed by four sheet members (film members) 361, 362, 363, and 364 that form the outer surface. The four sheet members 361, 362, 363, 364 are each substantially rectangular in a state before being attached to each other as a gusset bag.

  The first sheet member 361 forms the upper surface of the liquid storage portion 32a. The first sheet member 361 is formed with a crease (gusset) 367 extending in the axial direction (Y-axis direction) of the liquid supply part 42 in the vicinity of the center in the width direction of the liquid storage part 32a. The second sheet member 362 faces the first sheet member 361 and forms the bottom surface of the liquid storage portion 32a. The second sheet member 362 is formed with a fold (gusset) 368 extending in the axial direction (Y-axis direction) of the liquid supply part 42 in the vicinity of the center in the width direction of the liquid storage part 32a. The third sheet member 363 mainly forms the right side surface (−X axis direction side) of the liquid storage portion 32a. The fourth sheet member 364 faces the third sheet member 363 and mainly forms the left side surface (+ X axis direction side) of the liquid storage portion 32a. The upper edge portion of the third sheet member 363 is attached to the edge portion of the first sheet member 361 on the −Y axis direction side by thermal welding or the like, and the upper edge portion of the fourth sheet member 364 is the first sheet member. It is affixed to the edge part which forms the periphery of 361 by heat welding. The lower end side portion of the third sheet member 363 is attached to the end side portion forming the periphery of the second sheet member 362 by heat welding or the like, and the lower end side portion of the fourth sheet member 363 is the other side of the second sheet member 362. It is affixed by the heat welding etc. to the edge part which forms the periphery. In addition, the end portion 363p on the + Y-axis direction side of the third sheet member 363 and the end portion 364p on the + Y-axis direction side of the fourth sheet member 364 are attached to each other by heat welding or the like. When pasting the end side part 363p and the end side part 354p, a part of the end side part 363p and one end side part 354p are connected so that the supply member 49 of the connection body 40 and the liquid storage part 32a communicate with each other. Are attached to the outer peripheral surface of the supply member 49 by heat welding or the like. Further, the −Y-axis direction end side portion of the third sheet member 363 and the −Y-axis direction side end portion of the fourth sheet member 364 are bonded to each other by heat welding or the like.
