Is formed. The attachment portion 53 is provided integrally with the connector portion 52, and has a cylindrical first cylindrical portion 53a provided on the outer periphery of the connector portion 52 so as to cover the connector portion 52, and a distal end of the first cylindrical portion 53a. And a second cylindrical portion 53b provided on the base end side so as to be folded outward. The outer diameter of the first cylindrical portion 53a is formed to be approximately the same as the inner diameter of the neck portion 24, and the inner diameter of the second cylindrical portion 53b is formed to be approximately the same as the outer diameter of the neck portion 24. Yes. Further, on the inner peripheral surface of the second cylindrical portion 53b, there is an attachment portion side fitting portion 53c that fits with the neck side fitting portion 24a formed at or near the distal end portion of the outer peripheral surface of the neck portion 24. Is formed. And the container connector 51 inserts the neck part 24 of the container 21 in the clearance gap between the 1st cylindrical part 53a and the 2nd cylindrical part 53b of the attaching part 53 of the container connector 51, and the 1st cylindrical part 53a and By fitting the attachment portion side fitting portion 53c of the second cylindrical portion 53b with the neck side fitting portion 24a of the neck portion 24 in a state where the neck portion 24 is sandwiched between the second cylindrical portion 53b, It is fixed to the container 21.

  Further, the bottom of the bottomed cylindrical connector portion 52 is a punched portion 54 that is punched by the opening member 61. Here, a thin portion 54 a is provided around the punched portion 54, and the punched portion 54 is easily punched by the opening member 61. Furthermore, a concave portion 54b is provided at the bottom of the connector portion 52 at a substantially central portion toward the container 21 side. The concave portion 54 b is a relief portion of the concave portion 65 in which the breakthrough portion 115 formed at the distal end portion of the joint member 110 is accommodated when the opening member 61 is pushed by the joint member 110. Thereby, the bottom part of the connector part 52 can contact | abut with the blade part 63 of the opening member 61, without interfering with the recessed part 65. FIG.

  Further, a stopper 55 constituted by a step is formed on the inner peripheral surface of the connector portion 52. The stopper 55 is engaged with the protrusion 66 of the opening member 61 so that the opening member 61 does not pull out into the container 21 when the opening member 61 punches the punching portion 54 of the container 21. It is configured.

  Furthermore, a locking portion 56 is formed on the inner peripheral surface of the connector portion 52 so as to project inward. For example, the locking portion 56 is provided in a convex ring shape so as to protrude in a ring shape on the inner side of the connector portion 52 on the proximal side of the stopper 55 on the inner peripheral surface of the connector portion 52. And the latching | locking part 56 latches with the sealing part 68 formed in the outer peripheral surface of the cylindrical part 62 of the unsealing member 61, and the unsealing member 61 does not pull out of the connector part 52 from the front end side. Like that.

  Further, a protective film 57 is attached to the distal end surface of the second cylindrical portion 53 b of the attachment portion 53 of the container connector 51. The protective film 57 is, for example, a tamper evidence film, and protects the connector portion 52 and the opening member 61 from dust, germs, and the like, and maintains a sanitary state. For example, when the liquid container body 20 is attached to the joint member 110, the protective film 57 is torn by the breakthrough portion 115 of the joint member 110. Here, the breakthrough portion 115 only needs to be able to apply a certain amount of concentrated pressure to the protective film 57. For example, the breakthrough portion 115 may be sharp or rounded. Thus, the protective film 57 is configured to be broken. Therefore, by confirming that the protective film 57 has not been peeled off or torn, the user can easily grasp that the container 21 has not been touched from the sealed state. . The protective film 57 is formed of a material having orientation so as not to interfere with the container connector 51 and the opening member 61 after being cut by the breakthrough portion 115. When the protective film 57 is cut, the protective film 57 is folded inward along the orientation direction. The container connector 51 and the opening member 61 may be retracted. Furthermore, the protective film 57 may be attached in a state where a tension is applied, and when it is torn, it may escape to the edge side of the second cylindrical portion 53b and retreat from the container connector 51 or the opening member 61. . Of course, an easily cut portion by half cut or the like may be provided at the break portion of the protective film 57.

<Opening member>
As shown in FIGS. 4 and 6, the opening member 61 is a separate member from the container connector 51, and a cylindrical portion 62 inserted into the container 21 when the punching portion 54 of the container connector 51 is punched. The blade portion 63 for punching the punching portion 54 of the container 21 and the communication portion 64 communicating with the joint member 110 are provided.

  The cylindrical portion 62 is formed so that the outer diameter is substantially the same as the inner diameter of the inner peripheral surface on the proximal end side with respect to the stopper 55 of the connector portion 52 of the container connector 51, and in the axial direction of the connector portion 52. The connector part 52 is slidably accommodated. Further, the proximal end portion of the cylindrical portion 62 is closed and formed flat.

  Further, as shown in FIG. 7, at least one blade portion 63 that is sharpened toward the container 21 side is formed on the base end surface of the cylindrical portion 62 so as to follow the edge portion. For example, a plurality of blade portions 63 are formed other than the edge portion W of a partial region of the proximal end surface of the cylindrical portion 62. Thereby, the punching portion 54 is punched by the blade portion 63 in the region corresponding to the region where the blade portion 63 is formed, but is not punched in the region corresponding to the region where the blade portion 63 is not formed, The region that has not been punched becomes a connecting portion that connects the connector portion 52 and the punching portion 54, and the connecting portion can prevent the punching portion 54 from floating in the container 21. Note that a plurality of blade portions 63 may be formed across all the edge portions of the base end surface of the cylindrical portion 62.

  When the unsealing member 61 is pushed by the joint member 110, the blade portion 63 moves to the container 21 side and punches the punching portion 54 at the bottom of the container connector 51. In addition, since the thin part 54a is formed in the container connector 51 and it is easy to punch out, the blade part 63 does not need to be provided.

  As shown in FIGS. 4 and 6, the proximal end surface of the cylindrical portion 62 is provided with a concave portion 65 that is substantially centered toward the container 21 side. The recess 65 is an escape portion in which the breakthrough portion 115 formed on the front end surface of the joint member 110 is stored when the opening member 61 is pushed by the joint member 110. Thereby, the base end surface of the cylindrical portion 62 can be brought into close contact with the distal end surface of the joint member 110 without being interfered with the breakthrough portion 115 of the joint member 110. Note that the joint member 110 and the opening member 61 may be positioned by housing the breakthrough portion 115 of the joint member 110 in the recess 65.

  Further, a protruding portion 66 projecting outward is formed continuously or intermittently at the distal end portion of the outer peripheral surface of the cylindrical portion 62. The protrusion 66 is locked by the stopper 55 when the opening member 61 is pushed by the joint member 110 and moves to the container 21 side in the connector portion 52, and regulates the pushing amount of the opening member 61, thereby opening the opening. The member 61 is prevented from being pulled out into the container 21. Note that the outer diameter of the protrusion 66 may be smaller than the inner diameter of the stopper 55 of the connector part 52 from the viewpoint of reducing the pressing force with which the joint member 110 presses the opening member 61. In order to prevent liquid leakage from the gap between the surface and the outer peripheral surface of the unsealing member 61, the inner diameter of the stopper 55 of the connector portion 52 is set to be approximately the same as or slightly larger than the inner diameter of the stopper 55 of the connector portion 52. You may provide so that it may press-contact.

  Further, sealing portions 67 and 68 projecting outward are provided on the proximal end side of the outer peripheral surface of the cylindrical portion 62. The sealing portion 67 includes, for example, a convex ring portion that protrudes in a ring shape on the outside, a separate sealing member such as a rubber packing and an O-ring, and the like. It is provided in the base end part of the part or in the vicinity of the base end part. Similar to the sealing portion 67, the sealing portion 68 is configured by, for example, a convex ring portion that protrudes in a ring shape on the outside, or a separate sealing member such as a rubber packing and an O-ring. In addition, the cylindrical portion 62 is provided at a midway portion on the proximal end side from the position where the locking portion 56 of the connector portion 52 abuts on the distal end side of the sealing portion 67 on the outer peripheral portion of the cylindrical portion 62. And the sealing parts 67 and 68 are press-contacted to the internal peripheral surface of the base end side rather than the latching | locking part 56 of the connector part 52. FIG. Thus, the sealing portions 67 and 68 prevent liquid leakage from occurring between the inner peripheral surface of the connector portion 52 and the outer peripheral surface of the opening member 61. Further, the unsealing member 61 is press-fitted and held on the inner peripheral surface of the connector portion 52 by the sealing portions 67 and 68, so that the unraveling inside the connector portion 52 and the blade portion 63 are prevented from being lost.

  In addition, a plurality of openings 69 are formed in the side surface portion of the cylindrical portion 62, and a communication portion 64 that connects the inside of the container 21 and the joint member 110 is formed inside. A plurality of openings 69 are formed at equal intervals over the entire circumference of the side surface of the cylindrical portion 62. Here, two openings 69 are formed at equal intervals over the entire circumference of the side surface of the cylindrical portion 62. One or three or more openings 69 may be formed, or may be formed at non-uniform intervals. Further, the opening 69 is formed so as to be disposed between the sealing portions 67 and 68 in the axial direction of the cylindrical portion 62. When the opening member 61 punches the punched portion 54 at the bottom of the container connector 51 and enters the inside of the container 21, the opening 69 takes in the liquid inside the container 21, conducts water to the communicating portion 64, A liquid is supplied to the member 110.

  In assembling the opening mechanism 40 as described above, as shown in FIG. 4, the entire opening member 61 is a connector part with the blade part 63 of the opening member 61 as the insertion end from the distal end side of the connector part 52 of the container connector 51. It is inserted until it enters in 52. Thereafter, the protective film 57 is adhered to the distal end surface of the second cylindrical portion 53 b of the attachment portion 53 of the container connector 51. The container connector 51 into which the opening member 61 is inserted is fixed to the container 21 by fitting the attachment portion 53 to the neck portion 24 of the container 21.

  Furthermore, the bottom surface portion 90 a of the container holding member 90 protrudes toward the other end side in the height direction Z, and when the liquid container body 20 is stored in the container holding member 90, the liquid container body 20 A cylindrical positioning portion 91 in which the opening mechanism 40 is accommodated is provided. The positioning portion 91 is open at one end and the other end in the height direction Z, and has a through-hole 92 formed therein. Further, the positioning portion 91 is provided such that the tip end portion comes into contact with the bottom surface portion 80 a (projecting portion 81) of the joint holding member 80 when the container holding member 90 is attached to the joint holding member 80. Further, the positioning portion 91 is provided so that the size of the inner peripheral surface is substantially the same as the size of the outer peripheral surface of the opening mechanism 40 of the liquid container body 20. The positioning unit 91 positions the liquid container body 20 when the liquid container body 20 is stored in the container holding member 90. Specifically, the positioning unit 91 positions the opening mechanism 40 of the liquid container body 20 so that the axis of the opening mechanism 40 of the liquid container body 20 substantially matches the axis of the through-hole 92 of the positioning unit 91. Further, since the opening mechanism 40 of the liquid container body 20 is accommodated in the positioning portion 91, when the liquid container body 20 is accommodated in the container holding member 90, the one end face 22a of the storage box 22 and the container holding member are accommodated. The bottom surface portion 90a of the 90 can be reliably brought into contact.

  Furthermore, the side wall portion 90b of the container holding member 90 is formed to be, for example, substantially the same size or slightly larger in plan view than the liquid container body 20 (storage box 22). And is guided when the liquid container body 20 slides to the other end side in the height direction Z. That is, the side wall part 90 b functions as a positioning part for positioning the liquid container body 20 and also functions as a guide part when sliding the liquid container body 20.

  Further, the container holding member 90 has at least one rib (not shown) formed on the inner peripheral surface of the side wall 90b. The rib is provided with a return portion that bites into the storage box 22 of the liquid container body 20 held in the container holding member 90. Further, the return portion is provided so that the locking force biting into the storage box 22 is slightly smaller than the fitting force between the container holding member 90 and the joint holding member 80. Accordingly, the liquid container body 20 held in the container holding member 90 has a force that is greater than the locking force between the storage box 22 and the return portion and less than the fitting force between the container holding member 90 and the joint holding member 80. Thus, the container holding member 90 can be detached from the container holding member 90 without being separated from the joint holding member 80 by being lifted to one end side in the height direction Z. Furthermore, the container holding member 90 can be detached from the joint holding member 80 when it is lifted to one end in the height direction Z by a force greater than the fitting force between the container holding member 90 and the joint holding member 80.

  Furthermore, a grip portion 94 that is gripped by the user is provided at one end portion in the height direction Z of the side wall portion 90b. For example, the grip portion 94 includes a bent portion in which one end portion in the height direction Z of the side wall portion 90b is bent outward. Therefore, when the container holding member 90 is separated from the joint holding member 80 and wipes and cleans the liquid accumulated in the joint holding member 80, the user can easily hold the holding portion 94 in the height direction. It can be pulled up to one end of Z. Note that the grip portion 94 is not limited to be formed of a bent portion, and may be any conventionally known configuration as long as the user can grip the container holding member 90. For example, In addition, a user's finger or the like formed on the bottom surface portion 90a or the side wall portion 90b may be configured as a through-hole that can be inserted.

  Furthermore, the container holding member 90 has the other end side wall portion 90c that protrudes toward the other end side in the height direction Z on the entire circumference of the bottom surface portion 90a. The other end side wall portion 90c is provided such that the shape and size of the inner peripheral surface thereof are substantially the same shape and size as the flange portion 83 of the joint holding member 80 when viewed in plan. Then, when the container holding member 90 is attached to the joint holding member 80, the outer peripheral surface of the second wall 83b of the flange portion 83 of the joint holding member 80 is brought into contact with the inner peripheral surface of the other end side wall 90c. The container holding member 90 is positioned on the joint holding member 80 and is guided when the container holding member 90 slides to the other end side in the height direction Z.

<Joint material>
As shown in FIG. 4, the joint member 110 includes a tubular portion 111 in which a water passage 111 a is formed and a side surface portion is formed with an intake opening 111 b communicating with the water passage 111 a. 111 is slidable in the axial direction of 111, and covers and exposes the intake opening 111b, and urges the shutter 112 to cover the intake opening 111b when the liquid container body 20 is not attached. And an urging portion 113 that performs the above operation.

  The tubular portion 111 is formed in a tubular shape, and a water passage 111a is formed inside. Further, as shown in FIG. 3, the cylindrical portion 111 is provided upright on the bottom surface portion 80 a of the joint holding member 80 of the mounting mechanism 30.

  Further, as shown in FIGS. 4 and 9, a flange portion 114 projecting outward is formed on the distal end side of the side surface portion of the cylindrical portion 111. The flange portion 114 is formed so that the outer diameter is substantially the same as the inner diameter of the cylindrical portion 62 of the opening member 61. The flange portion 114 is in pressure contact with the inner peripheral surface of the tubular portion 62 of the opening member 61 when the joint member 110 is inserted into the tubular portion 62 of the opening member 61. Further, a plurality of intake openings 111 b are formed on the distal end side of the side surface portion of the cylindrical portion 111 on the proximal end side with respect to the flange portion 114. For example, two intake openings 111 b are formed at equal intervals on the side surface of the cylindrical portion 111. Note that one or three or more intake openings 111b may be formed on the side surface of the cylindrical portion 111, or may be formed at unequal intervals.

  Further, a breakthrough portion 115 having a sharp tip is formed on the tip surface of the cylindrical portion 111. Therefore, when the liquid container body 20 is attached to the joint member 110, the protective film 57 can be cut off by the breakthrough portion 115, so that the step of peeling the protective film 57 from the container connector 51 can be omitted.

  As shown in FIGS. 4 and 9, the shutter portion 112 is formed in a cylindrical shape, and is provided on the outer periphery of the cylindrical portion 111 so as to be slidable in the axial direction of the cylindrical portion 111. Furthermore, the shutter portion 112 is formed so that the outer diameter is substantially the same as the inner diameter of the cylindrical portion 62 of the opening member 61. As a result, the shutter portion 112 is press-fitted into the cylindrical portion 62 of the opening member 61 without any gap, and leakage of water from between the shutter portion 112 and the opening member 61 can be prevented.

  In addition, a protrusion 116 protruding outward is continuously or intermittently formed at the proximal end portion of the outer peripheral surface of the shutter portion 112. When the shutter portion 112 is inserted into the cylindrical portion 62 of the opening member 61, the protrusion 116 is locked to the base end surface of the cylindrical portion 62 of the opening member 61. Then, when the liquid container body 20 is moved to the proximal end side of the joint member 110, the shutter portion 112 is moved to the proximal end side against the urging force of the urging portion 113, as shown in FIG. As shown, the intake opening 111b of the cylindrical portion 111 is exposed. On the other hand, when the liquid container body 20 is moved to the distal end side of the joint member 110 such as removing the liquid container body 20 from the joint member 110, the shutter section 112 moves to the distal end side by the urging force of the urging portion 113. Then, as shown in FIG. 9B, the intake opening 111b of the cylindrical portion 111 is covered.

  As shown in FIGS. 4 and 9, a sealing portion 117 is provided at the distal end portion of the outer peripheral surface of the shutter portion 112 so as to protrude outward. The sealing portion 117 is composed of, for example, a convex ring portion that protrudes in a ring shape on the outside, a separate sealing member such as a rubber packing and an O-ring, and the like. It is provided in the front-end | tip part of an outer peripheral surface. The sealing portion 117 is pressed against the inner peripheral surface of the cylindrical portion 62 of the opening member 61 when the shutter portion 112 is inserted into the cylindrical portion 62 of the opening member 61. As a result, the sealing portion 117 prevents liquid leakage from the gap between the inner peripheral surface of the cylindrical portion 62 of the opening member 61 and the outer peripheral surface of the shutter portion 112.

  As shown in FIG. 3, the urging portion 113 is composed of, for example, a compression spring or a permanent magnet, and includes a bottom surface portion 80 a of the joint holding member 80 on the outer periphery of the cylindrical portion 111 and a base end surface of the shutter portion 112. Between the two. When the liquid container body 20 is not attached to the joint member 110 or is removed from the joint member 110, the urging portion 113 is in contact with the proximal end surface of the flange portion 114 of the tubular portion 111 when the shutter portion 112 is removed. Thus, the shutter portion 112 is biased toward the distal end portion (flange portion 114) so that the shutter portion 112 covers the intake opening 111b of the cylindrical portion 111.

<Mounting method>
Next, an attachment method for attaching the liquid container body 20 to the attachment mechanism 30 in the liquid supply apparatus 1 having the above configuration will be described.

As an insertion end, the opening mechanism 40 of the liquid container body 20 is inserted into the container holding member 90 of the mounting mechanism 30 while being inserted into the positioning portion 91 of the container holding member 90. 10, the unsealing mechanism 40 of the liquid container body 20 is housed in the positioning portion 91 of the container holding member 90, and the liquid container body 20 is housed as shown in FIG. The liquid container body 20 is inserted into the container holding member 90 of the mounting mechanism 30 until the one end surface 22a of the box 22 and the bottom surface portion 90a of the container holding member 90 abut.

  At this time, as shown in FIG. 10, the liquid supply apparatus 1 is configured such that the liquid container body 20 is first inserted into the container holding member 90, and the opening mechanism 40 of the liquid container body 20 is positioned by the positioning portion of the container holding member 90. When housed in 91, as shown in FIG. 11, the protective film 57 of the liquid container body 20 is torn by the breakthrough portion 115 of the joint member 110. Therefore, the liquid supply apparatus 1 can omit the step of peeling the protective film 57 from the container 21 of the liquid container body 20. The liquid supply apparatus 1 may peel off the protective film 57 before inserting the liquid container body 20 into the container holding member 90.

  Next, when the liquid container body 20 is further moved to the other end side in the height direction Z, the liquid supply device 1 causes the shutter portion 112 of the joint member 110 to protrude from the shutter portion 112 as shown in FIG. It is inserted into the opening member 61 until the portion 116 and the proximal end surface of the cylindrical portion 62 of the opening member 61 are locked. At this time, the joint member 110 can prevent the shutter portion 112 from being press-fitted into the opening member 61 without a gap, and leakage of water from between the joint member 110 and the opening member 61 can be prevented.

  Next, in the liquid supply apparatus 1, when the liquid container body 20 is further moved to the other end side in the height direction Z, the shutter portion 112 resists the urging force of the urging portion 113 as shown in FIG. Then, the intake opening 111b of the cylindrical portion 111 is exposed in the opening member 61.

  Next, as shown in FIG. 14, in the liquid supply apparatus 1, the liquid container body 20 is further moved to the other end side in the height direction Z, and the one end face 22 a of the storage box 22 of the liquid container body 20 and the container holding When the bottom surface portion 90a of the member 90 is brought into contact, as shown in FIG. 15, the container connector 51 is moved to the other end side in the height direction Z and the opening member 61 of the joint member 110 is moved. The blade part 63 punches the punching part 54 at the bottom of the container connector 51. In the liquid supply apparatus 1, the intake opening 111 b of the cylindrical portion 111 of the joint member 110 is exposed from the connector portion 52. Thereby, the inside of the container 21 of the liquid container body 20, the opening 69 of the opening member 61, the intake opening 111b of the tubular portion 111 of the joint member 110, and the water passage 111a communicate with each other. Thereby, the liquid in the container 21 is supplied to the liquid supply apparatus 1 via the container connector 51 and the joint member 110.

  As described above, the liquid supply apparatus 1 can attach the liquid container body 20 to the mounting mechanism 30.

<Removal method>
Next, a method of removing the liquid container body 20 from the mounting mechanism 30 in the liquid supply apparatus 1 having the above configuration will be described.

  First, as shown in FIG. 16, when the liquid container body 20 is lifted to one end side in the height direction Z from the state in which the liquid container body 20 is mounted on the mounting mechanism 30 by the user, As shown in FIG. 17, the connector portion 52 of the opening mechanism 40 is moved to one end side in the height direction Z, and the opening member 61 of the opening mechanism 40 is accommodated in the connector portion 52.

  Next, when the liquid container body 20 is further moved to one end side in the height direction Z, the liquid supply device 1 is moved in the height direction by the urging force of the urging portion 113 as shown in FIG. It moves to the one end side of Z, and the opening part 111b of the cylindrical part 111 is covered in the opening member 61 by the shutter part 112.

  Next, when the liquid container body 20 is further moved to one end side in the height direction Z, the liquid supply device 1 takes out the shutter portion 112 from the opening member 61 as shown in FIG. The protruding state 116 and the proximal end surface of the cylindrical portion 62 of the opening member 61 are released, and the opening mechanism 40 is detached from the joint member 110.

  Next, as shown in FIG. 20, when the liquid container body 20 is further lifted to one end side in the height direction Z, the liquid container body 20 is taken out from the container holding member 90, and the liquid container body 20 The body 20 is detached from the mounting mechanism 30.

  As described above, the liquid supply apparatus 1 can remove the liquid container body 20 from the mounting mechanism 30.

<Effect>
As described above, in the liquid supply apparatus 1 to which the present invention is applied, since the unsealing member 61 housed in the connector portion 52 of the container connector 51 functions as an insertion guide portion of the joint member 110, the joint member 110 leaks water. Can be prevented. That is, the liquid supply apparatus 1 can easily and correctly mount the liquid container body 20 having the heavy container 21 filled with the liquid to the mounting mechanism 30.

  Moreover, since the container holding member 90 is detachably provided on the joint holding member 80 in the liquid supply apparatus 1, the container holding member 90 can be detached from the joint holding member 80 as shown in FIG. Even if the container holding member 90 is provided with the cylindrical positioning portion 91 that accommodates the opening mechanism 40 of the liquid container body 20, the container holding member 90 adheres to the joint member 110 and the joint holding member 80 in the positioning portion 91 of the container holding member 90. Liquids, dust, germs, etc. can be easily wiped off and can be easily cleaned. Therefore, the liquid supply apparatus 1 can maintain a sanitary state more easily than in the past.

  Furthermore, the liquid supply apparatus 1 is provided with a lower portion 82 that is one step lower than the protrusion 81 around the protrusion 81 to which the joint member 110 is attached, on the bottom surface portion 80a of the joint holding member 80. When 20 is removed from the joint member 110, spilled liquid accumulates in the low portion 82, so that leakage of water between the joint member 110 and the protrusion 81 can be prevented. Furthermore, since the liquid supply apparatus 1 collects the spilled liquid in the lower portion 82, the liquid supply apparatus 1 can wipe off the liquid more easily than the conventional liquid supply apparatus and can be cleaned more easily than the conventional liquid supply apparatus. . Therefore, the liquid supply apparatus 1 can maintain a sanitary state more easily than in the past.

  Further, the liquid supply apparatus 1 is configured such that the outer peripheral surface of the flange portion 83 of the side wall portion 80b of the joint holding member 80 and the inner peripheral surface of the other end side wall portion 90c of the container holding member 90 come into contact with each other. The axis of the joint member 110 and the axis of the through-hole 92 of the positioning portion 91 of the container holding member 90 are positioned so as to substantially coincide with each other. Furthermore, the liquid supply apparatus 1 is configured such that the liquid container body 20 is in a state where the container 21 is stored in the storage box 22, and the one end surface 22 a on the opening mechanism 40 side of the storage box 22 is used as an insertion end. When the unsealing mechanism 40 is inserted into the container holding member 90 of the mounting mechanism 30 while being inserted into the positioning portion 91 of the container holding member 90, the opening mechanism of the liquid container body 20 is inserted by the positioning portion 91 of the container holding member 90. The positioning is performed so that the 40 axis and the axis of the through-hole 92 of the positioning portion 91 of the container holding member 90 substantially coincide with each other. That is, in the liquid supply apparatus 1, when the opening mechanism 40 of the liquid container body 20 is accommodated in the positioning portion 91 of the container holding member 90, the axis of the opening mechanism 40 of the liquid container body 20 and the joint member of the joint holding member 80. Positioning is performed so that the axis of 110 substantially matches. Therefore, the liquid supply apparatus 1 uses the liquid container body 20 with the one end face 22a on the side of the opening mechanism 40 of the storage box 22 as the insertion end while the container 21 is still stored in the storage box 22. The opening mechanism 40 is inserted into the positioning portion 91 of the container holding member 90 while being inserted into the container holding member 90 of the mounting mechanism 30, so that the axis of the opening mechanism 40 of the liquid container body 20 The joint holding member 80 can be arranged so that the axis of the joint member 110 substantially coincides, and the liquid container body 20 can be easily and correctly mounted on the mounting mechanism 30.

  Further, in the liquid supply apparatus 1, when the liquid container body 20 is inserted into the container holding member 90 and the opening mechanism 40 of the liquid container body 20 is stored in the positioning portion 91 of the container holding member 90, the liquid container body 20. Is positioned so that the axis of the unsealing mechanism 40 and the axis of the through-hole 92 of the positioning portion 91 of the container holding member 90 substantially coincide with each other, for example, the storage box 22 of the liquid container body 20 is crushed during transportation or storage. Can be positioned so that the axis of the opening mechanism 40 of the liquid container body 20 and the axis of the through-hole 92 of the positioning portion 91 of the container holding member 90 substantially coincide with each other. The mounting mechanism 30 can be easily and correctly mounted.

  Further, in the liquid supply apparatus 1, the intake opening 111 b of the cylindrical portion 111 of the joint member 110 is covered with the shutter portion 112 when the liquid container body 20 is not attached. Further, when the liquid container body 20 is attached, the joint member 110 operates to expose the intake opening 111b of the tubular portion 111 in the opening member 61 after the shutter portion 112 is inserted into the opening member 61. Done. Furthermore, when the liquid container body 20 is removed, the joint member 110 operates to cover the intake opening 111b of the tubular portion 111 in the opening member 61 in a state where the shutter 112 is inserted into the opening member 61. Done. Accordingly, the joint member 110 has the intake opening 111b of the cylindrical portion 111 cut off from the outside when the liquid container body 20 is not attached, attached, or removed, and the cylindrical portion 111 is disconnected. It is possible to prevent dust, germs, and the like from adhering to the intake opening 111b. Therefore, the liquid supply apparatus 1 can prevent dust, germs, and the like from entering the liquid supply apparatus 1 from the intake opening 111b of the cylindrical portion 111, and can maintain a sanitary state.

  Furthermore, as described above, the liquid supply device 1 has the cylindrical portion because the shutter portion 112 covers the intake opening 111b of the cylindrical portion 111 of the joint member 110 when the liquid container body 20 is not attached. Although it is possible to prevent dust, germs and the like from adhering to the intake opening 111b of 111 (the base end surface of the flange portion 114 and the front end surface of the shutter portion 112), the front end surface of the flange portion 114 and the shutter portion 112 There is a risk that dust, germs, etc. may adhere to the outer peripheral surface.

  However, as shown in FIG. 15, when the liquid in the container 21 of the liquid container body 20 is supplied to the liquid supply apparatus 1, the flange portion 114 of the joint member 110 is connected to the cylindrical portion of the unsealing member 61. Since it is press-contacted to the inner peripheral surface of 62, the space part of the base end side rather than the flange part 114 in the cylindrical part 62 of the opening member 61 is sealed. That is, the liquid supply apparatus 1 prevents the front end surface of the flange portion 114 of the joint member 110 from coming into contact with the liquid in the container 21. Therefore, in the liquid supply apparatus 1, even if dust or germs or the like adhere to the front end surface side of the flange portion 114 of the joint member 110, the dust or germs or the like attached to the front end surface of the flange portion 114 remains in the cylindrical portion 111. Intrusion into the interior of the liquid supply apparatus 1 from the intake opening 111b can be prevented, and a sanitary condition can be maintained.

  Furthermore, since the sealing part 117 of the shutter part 112 is press-contacted with the internal peripheral surface of the cylindrical part 62 of the opening member 61, the liquid supply apparatus 1 makes the outer peripheral surface of the shutter part 112 be a container by the sealing part 117. This prevents contact with 21 liquids. Accordingly, in the liquid supply apparatus 1, even if dust or germs adhere to the outer peripheral surface of the shutter portion 112, the dust or germs attached to the outer peripheral surface of the shutter portion 112 may be taken in the intake opening of the cylindrical portion 111. It is possible to prevent intrusion into the liquid supply apparatus 1 from 111b and maintain a sanitary condition.

<First modification>
In the liquid supply apparatus 1, the outer peripheral surface of the second wall portion 83 b of the flange portion 83 of the joint holding member 80 is brought into contact with the inner peripheral surface of the other end side wall portion 90 c of the container holding member 90, so The joint holding member 80 is not limited to being fitted therein, and the outer peripheral surface of the side wall 90b of the container holding member 90 is the inner periphery of the side wall 80b of the joint holding member 80 as shown in FIG.

  Specifically, as shown in FIG. 21, the container holding member 90 has a bottom surface portion 90 a on which the positioning portion 91 is formed and a height on the entire circumference of the bottom surface portion 90 a without providing the other end side wall portion 90 c. And a side wall 90b projecting toward one end in the direction Z. Further, the bottom surface portion 90 a is formed with a through-hole 95 that serves as a gripping portion that is gripped by the user when the container holding member 90 is fitted into the joint holding member 80 or taken out from the joint holding member 80. . As shown in FIG. 22, for example, a plurality of through-holes 95 serving as gripping portions are formed on the bottom surface portion 90 a at equal intervals around the axis of the through-hole 92 of the positioning portion 91. Here, the four through-holes 95 are formed in the bottom face part 90a at equal intervals around the axis of the through-hole 92 of the positioning part 91. In addition, the number and arrangement positions of the through-holes 95 are not limited to this, and can be appropriately changed as long as the user can hold them.

Furthermore, as shown in FIG. 21, the joint holding member 80 has a stopper 84 formed of a step on the side wall 80b. The stopper 84 is engaged with the bottom surface portion 90 a of the container holding member 90 to restrict the movement of the container holding member 90 on the other end side in the height direction Z. Specifically, the side wall portion 80b includes a first wall portion 80b ₁ which is provided toward the one end side in the height direction Z on the bottom portion 80a, the outside one end of the first wall portion 80b ₁ of the height direction Z The second wall portion 80b ₂ is provided so as to protrude, and the third wall portion 80b ₃ is provided at the tip of the second wall portion 80b ₂ toward one end side in the height direction. The second wall portion 80 b ₂ serves as a stopper 84 that is locked to the bottom surface portion 90 a of the container holding member 90. The third wall portion 80b ₃ is formed to have, for example, substantially the same size as the container holding member 90 in plan view, and positions the container holding member 90 on the joint holding member 80, and the container holding member 90 has a height. Guide when sliding to the other end of the direction. Specifically, the third wall portion 80b ₃ moves the container holding member 90 so that the axis of the through hole 92 of the positioning portion 91 of the container holding member 90 substantially coincides with the axis of the joint member 110 of the joint holding member 80. The joint holding member 80 is positioned. That is, the third wall portion 80b ₃ functions as a positioning portion for positioning the container holding member 90 and also functions as a guide portion when sliding the container holding member 90.

  Even in the liquid supply apparatus 1 in which the container holding member 90 is fitted in such a joint holding member 80, the same as the liquid supply apparatus 1 in which the joint holding member 80 is fitted in the container holding member 90 described above. In addition, since the container holding member 90 is detachably provided on the joint holding member 80, the container holding member 90 is removed from the joint holding member 80, so that the opening mechanism 40 of the liquid container body 20 is accommodated in the container holding member 90. Even if the cylindrical positioning portion 91 is provided, the liquid, dust, germs and the like attached to the positioning member 91 of the container holding member 90, the joint member 110 and the joint holding member 80 can be easily wiped off. Easy to clean. Therefore, the liquid supply apparatus 1 can maintain a sanitary state more easily than in the past.

  Further, the liquid supply apparatus 1 can hold the joint even when the container holding member 90 is fitted in the joint holding member 80, as in the case where the joint holding member 80 is fitted in the container holding member 90 described above. The member 80 is positioned such that the axis of the joint member 110 and the axis of the through-hole 92 of the positioning portion 91 of the container holding member 90 substantially coincide. Furthermore, the liquid supply apparatus 1 is configured such that the liquid container body 20 is in a state where the container 21 is stored in the storage box 22, and the one end surface 22 a on the opening mechanism 40 side of the storage box 22 is used as an insertion end.
