Description

Technical Field

[0001] The present invention relates to a liquid-containing container. Background Art

[0002] Conventionally, there has been an ink cartridge that houses an ink bag and replaces the ink bag and reuses the housing and the lid that house the ink bag. In the technology of Patent Document 1, the lid is fixed to the housing by the engagement of a pair of corners provided on the lid with a pair of hole portions provided on the housing, and the snap fit of a pair of claws provided on the lid with a pair of recesses provided on the housing. Further, a label printed with cautionary words is pasted from the surface of the notch portion to the upper surface of the lid. When removing the lid, the lid can be removed from the housing by inserting a tool into the notch portion of the housing and prying it up.

[0003] With such a structure, unlike the case where the lid is ultrasonically welded to the housing, the internal ink bag can be replaced and the housing and lid of the ink cartridge can be reused to regenerate the ink cartridge. Further, since the label is pasted on the ridge line between the housing and the lid, it is possible to prevent the lid from coming off due to the vibration or dropping of the ink cartridge. Moreover, since the label is pasted so as to cover the notch portion, it is possible to prevent the user from intentionally opening the lid.

[0007] However, in the ink cartridge described in Patent Document 1, there are the following problems. That is, there are cases where the label pasted on the surface of the ink cartridge adheres tightly to the surface of the ink cartridge due to temperature changes and becomes difficult to peel off, increasing the workload of the operator when removing the lid from the housing. In addition, there are cases where when using a tool to peel off the label adhering tightly to the surface of the ink cartridge, the housing and lid of the ink cartridge are damaged, and the reuse of the housing and lid is hindered. There are also cases where the claws provided on the lid cannot maintain sufficient elasticity due to the heat history and are damaged when removing the lid from the housing. As a result, the reuse of the lid is hindered. Summary of the Invention

[0008] According to one aspect of the present invention, there is provided a liquid-containing container. The liquid-containing container includes: a bag portion that houses a liquid; and a pair of components that are reused when replacing the used bag portion and reconstituting the liquid-containing container. The pair of components are fixed to each other by one or more riveting pins. Brief Description of the Drawings

Detailed Embodiment

[0027] A. First Embodiment:

[0028] Figure 1 is a perspective view showing the liquid containing container 100a of the first embodiment. Figure 2FIG. 0 is an exploded perspective view of a liquid container 100a showing a first embodiment. The liquid container 100a contains liquid. The liquid container 100a is installed in a liquid consuming device and supplies the contained liquid to the liquid consuming device.

[0029] In Figure 1 , arrows indicating the X-axis direction, Y-axis direction, and Z-axis direction that are orthogonal to each other are shown. The Y-axis direction corresponds to the length direction of the liquid container 100a. The Y-axis direction corresponds to the insertion direction when the liquid container 100a is installed in the liquid consuming device. The X-axis direction corresponds to the width direction of the liquid container 100a. The Z-axis direction corresponds to the height direction of the liquid container 100a. The X-axis, Y-axis, and Z-axis shown in other figures correspond to the Figure 1 shown X-axis, Y-axis, and Z-axis.

[0030] The liquid container 100a includes a bag portion 110, a fixing member 120a, a first housing 130a, a second housing 140a, and a lid portion 150a. The first housing 130a, the second housing 140a, and the lid portion 150a constitute an outer shell 100Sa of the liquid container 100a (see Figure 1 ). The outer shell 100Sa surrounds the bag portion 110. More specifically, the outer shell 100Sa is a substantially rectangular parallelepiped housing that houses the bag portion 110. When the used bag portion 110 and the fixing member 120a are replaced and the liquid container 100a is reconstituted, the outer shell 100Sa is reused.

[0031] The bag portion 110 contains liquid (see Figure 2 ). The bag portion 110 is made of a flexible sheet. The liquid contained in the bag portion 110 is supplied to the outside, and as the amount of liquid in the bag portion 110 decreases, the bag portion 110 contracts. At this time, the bag portion 110 mainly contracts in the Z-axis direction.

[0032] The fixing member 120a is a member for fixing the bag portion 110 to the outer shell 100Sa (see Figure 2 ). The bag portion 110 is mounted on the fixing member 120a. The fixing member 120a has a liquid flow path that communicates with the inside of the bag portion 110. The liquid flow path supplies the liquid in the bag portion 110 to the outside of the liquid container 100a. In Figure 1 and Figure 2 , the liquid flow path is provided along the Y-axis direction. In Figure 1 and Figure 2 , the opening of the liquid flow path in the fixing member 120a is sealed with a rectangular film.

[0033] The first housing 130a includes a first wall 131a, a second wall 132a, a third wall 133a, and a fourth wall 134a (seeFigure 2 )。The first wall 131a, the second wall 132a, the third wall 133a, and the fourth wall 134a are each substantially rectangular flat plate portions. In addition, in this specification, a "wall" is a flat plate portion and may have steps, grooves, bent portions, inclined surfaces, holes, and slits, etc.

[0034] The first wall 131a is Figure 1 and Figure 2 a substantially rectangular flat plate portion arranged parallel to the XY plane. The second wall 132a is a flat plate portion extending from one long side of the first wall 131a in a direction perpendicular to the first wall 131a. The third wall 133a is a flat plate portion extending from the other long side of the first wall 131a in a direction perpendicular to the first wall 131a. The second wall 132a and the third wall 133a are opposed to each other. The fourth wall 134a is a flat plate portion extending from one short side of the first wall 131a in a direction perpendicular to the first wall 131a. One short side of the fourth wall 134a is connected to one short side of the second wall 132a. The other short side of the fourth wall 134a is connected to one short side of the third wall 133a.

[0035] In the first housing 130a, a part of the bag portion 110 is accommodated in a substantially rectangular parallelepiped space surrounded by the first wall 131a, the second wall 132a, the third wall 133a, and the fourth wall 134a (see Figure 2 ).

[0036] The first wall 131a has six holes CPH10a to CPH60a (see Figure 2 ). The holes CPH10a to CPH60a are arranged in the order of CPH10a to CPH60a along the long side of the first wall 131a that is not connected to the fourth wall 134a among the two long sides. In Figure 2 , the holes CPH10a to CPH60a are arranged in the X-axis direction.

[0037] The second housing 140a includes a first wall 141a, a second wall 142a, a third wall 143a, and a fourth wall 144a (see Figure 2 ). The first wall 141a has six holes CPH10aB to CPH60aB. In Figure 1 and Figure 2 , the fifth wall 155a and the holes CPH10aB to CPH30aB are not shown.

[0038] In a state where the liquid storage container 100a is formed, the second housing 140a has a shape that is substantially symmetric to the first housing 130a with respect to a plane parallel to the XY plane. In the second housing 140a, another part of the bag portion 110 is accommodated in a substantially rectangular parallelepiped space surrounded by the first wall 141a, the second wall 142a, the third wall 143a, and the fourth wall 144a (see Figure 2 ).

[0039] The lid portion 150a includes a first wall 151a, a second wall 152a, a third wall 153a, a fourth wall 154a, and a fifth wall 155a (see Figure 2 ). The first wall 151a, the second wall 152a, the third wall 153a, the fourth wall 154a, and the fifth wall 155a are each substantially rectangular flat plate-like portions.

[0040] In Figure 1 and Figure 2 , the first wall 151a is a substantially rectangular flat plate-like portion arranged parallel to the ZX plane. The second wall 152a is a flat plate-like portion extending from one short side of the first wall 151a in a direction perpendicular to the first wall 151a. The third wall 153a is a flat plate-like portion extending from the other short side of the first wall 151a in a direction perpendicular to the first wall 151a. The second wall 152a and the third wall 153a are opposed to each other.

[0041] The fourth wall 154a is a flat plate-like portion extending from one long side of the first wall 151a in a direction perpendicular to the first wall 151a. The fifth wall 155a is a flat plate-like portion extending from the other long side of the first wall 151a in a direction perpendicular to the first wall 151a. The fourth wall 154a and the fifth wall 155a are opposed to each other.

[0042] One short side of the fourth wall 154a is connected to one short side of the second wall 152a. The other short side of the fourth wall 154a is connected to one short side of the third wall 153a. One short side of the fifth wall 155a is connected to the other short side of the second wall 152a. The other short side of the fifth wall 155a is connected to the other short side of the third wall 153a.

[0043] In the lid portion 150a, in a substantially rectangular parallelepiped space surrounded by the first wall 151a, the second wall 152a, the third wall 153a, the fourth wall 154a, and the fifth wall 155a, another part of the bag portion 110 and the fixing member 120a are accommodated (see Figure 2 ).

[0044] The first wall 151a has a hole 156a. The hole 156a is disposed substantially at the center of the first wall 151a. The hole 156a penetrates the first wall 151a in a direction perpendicular to the first wall 151a. The fixing member 120a is fixed to the first wall 151a with a part of the fixing member 120a disposed within the hole 156a. As a result, the bag portion 110 is fixed to the housing 100Sa. The liquid flow path of the fixing member 120a passes through the hole 156a and communicates with the outside (see Figure 1 ). In Figure 1 , the end of the liquid flow path of the fixing member 120a is sealed with a rectangular film.

[0045] The fourth wall 154a has six protrusions CP10a to CP60a. The protrusions CP10a to CP60a are arranged in the order of protrusions CP10a to CP60a along the long side of the two long sides of the fourth wall 154a that is not connected to the first wall 151a. In Figure 2 , the protrusions CP10a to CP60a are arranged in the X-axis direction. The protrusions CP10a to CP60a protrude in a direction perpendicular to the fourth wall 154a. In Figure 2 , the protrusions CP10a to CP60a protrude in the positive Z-axis direction.

[0046] The protrusions CP10a to CP60a function as riveting pins. In this specification, a "riveting pin" refers to a component that is applied to a pair of components to be fixed to each other and can fix the pair of components by deforming the tip. The function of the protrusions CP10a to CP60a will be described later.

[0047] The fifth wall 155a has six protrusions CP10aB to CP60aB. In a state where the liquid storage container 100a is formed, the fifth wall 155a has a shape that is substantially symmetric to the fourth wall 154a with respect to a plane parallel to the XY plane. In Figure 1 and Figure 2 , the fifth wall 155a and the six protrusions CP10aB to CP60aB are not shown.

[0048] When forming the liquid storage container 100a, there are provided a fixing member 120a to which the bag portion 110 is mounted, a first housing 130a, a second housing 140a, and a lid portion 150a (see Figure 2 ). The fixing member 120a is mounted on the lid portion 150a. Then, the first housing 130a and the second housing 140a are assembled while sandwiching the lid portion 150a and the bag portion 110.

[0049] Figure 3 is a top view of the liquid storage container 100a. Figure 4 is Figure 3Cross-sectional view taken along line IV-IV. When the first housing 130a and the second housing 140a are assembled, the protrusions CP10a to CP60a of the lid portion 150a are respectively inserted into the holes CPH10a to CPH60a of the first housing 130a (see Figures 2 to 4 ). Then, when the lid portion 150a, the first housing 130a, and the second housing 140a are first used to form the liquid storage container 100a, the tips of the protrusions CP30a and CP60a, which are the protrusions at both ends among the protrusions CP10a to CP60a, are deformed (see Figure 1 , Figure 3 and Figure 4 ). That is, the tips of the protrusions CP30a and CP60a are respectively enlarged to a size that cannot pass through the holes CPH30a and CPH60a. As a result, the first housing 130a and the lid portion 150a are fixed to each other by the protrusions CP30a and CP60a serving as riveting pins.

[0050] Similarly, the protrusions CP10aB to CP60aB of the lid portion 150a are respectively inserted into the holes CPH10aB to CPH60aB of the second housing 140a. Then, when the lid portion 150a, the first housing 130a, and the second housing 140a are first used to form the liquid storage container 100a, the tips of the protrusions CP30aB and CP60aB, which are the protrusions at both ends among the protrusions CP10aB to CP60aB, are deformed. That is, the tips of the protrusions CP30aB and CP60aB are respectively enlarged to a size that cannot pass through the holes CPH30aB and CPH60aB. As a result, the second housing 140a and the lid portion 150a are fixed to each other by the protrusions CP30aB and CP60aB serving as riveting pins.

[0051] That is, in the liquid storage container 100a, the lid portion 150a has six protrusions CP10a to CP60a, and these six protrusions CP10a to CP60a are configured to be able to fix the first housing 130a and the lid portion 150a to each other. The lid portion 150a also has six protrusions CP10aB to CP60aB, and these six protrusions CP10aB to CP60aB are configured to be able to fix the second housing 140a and the lid portion 150a to each other. Moreover, in the completed liquid storage container 100a, the first housing 130a and the lid portion 150a are fixed to each other by two of the six protrusions CP10a to CP60a, namely, the protrusions CP30a and CP60a. The second housing 140a and the lid portion 150a are fixed to each other by two of the six protrusions CP10aB to CP60aB, namely, the protrusions CP30aB and CP60aB.

[0052] After the liquid in the bag portion 110 is consumed, when the fixing member 120a of the liquid storage container 100a and the bag portion 110 are replaced and the liquid storage container 100a is constituted again, the following processing is performed. That is, the top ends of the protrusions CP30a, CP60a, CP30aB, and CP60a serving as riveting pins are damaged, and the first housing 130a, the second housing 140a, and the lid portion 150a are separated from each other. Then, the fixing member 120a and the bag portion 110 are taken out, and a new fixing member 120a and a new bag portion 110 are installed in the lid portion 150a. Then, the first housing 130a and the second housing 140a are assembled while clamping the lid portion 150a, the fixing member 120a, and the bag portion 110.

[0053] At this time, the top ends of the protrusions CP20a and CP50a among the protrusions CP10a to CP60a are deformed and are respectively enlarged to a size that cannot pass through the holes CPH20a and CPH50a (see Figure 1 , Figure 3 and Figure 4 ). As a result, in the second use, the first housing 130a and the lid portion 150a are fixed to each other by the protrusions CP20a and CP50a serving as riveting pins.

[0054] Similarly, the top ends of the protrusions CP20aB and CP50aB among the protrusions CP10aB to CP60aB are deformed and are respectively enlarged to a size that cannot pass through the holes CPH20aB and CPH50aB. As a result, in the second use, the second housing 140a and the lid portion 150a are fixed to each other by the protrusions CP20aB and CP50aB serving as riveting pins.

[0055] After the liquid in the replaced bag portion 110 is consumed, the fixing member 120a and the bag portion 110 of the liquid storage container 100a are replaced again, and when the liquid storage container 100a is constituted again, the same processing as above is also performed. However, the top ends of the protrusions CP10a and CP40a among the protrusions CP10a to CP60a are deformed and are respectively enlarged to a size that cannot pass through the holes CPH10a and CPH40a (see Figure 1 , Figure 3 and Figure 4 ). As a result, in the third use, the first housing 130a and the lid portion 150a are fixed to each other by the protrusions CP10a and CP40a serving as riveting pins.

[0056] Similarly, the tips of the protrusions CP10aB to CP60aB among the protrusions CP10aB to CP60aB are deformed and enlarged to sizes that cannot pass through the holes CPH10aB and CPH40aB, respectively. As a result, in the third use, the second housing 140a and the lid portion 150a are fixed to each other by the protrusions CP10aB and CP40aB acting as riveting pins.

[0057] With the structure of the first embodiment, when replacing the fixing member 120a and the bag portion 110 of the liquid storage container 100a and reconstituting the liquid storage container 100a later, even if the liquid storage container 100a undergoes temperature changes, the protrusions CP30a to CP60a and CP30aB to CP60aB acting as riveting pins can be broken, so that the first housing 130a, the second housing 140a, and the lid portion 150a can be easily separated and processed.

[0058] With the structure of the first embodiment, when reusing the first housing 130a, the second housing 140a, and the lid portion 150a, the first housing 130a and the lid portion 150a, and the second housing 140a and the lid portion 150a can be fixed by the protrusions CP10a to CP60a, CP10aB to CP60aB that have not been used so far. Therefore, when reusing the first housing 130a, the second housing 140a, and the lid portion 150a, the liquid storage container 100a can be reconstituted in such a way that the fixing strength between the first housing 130a, the second housing 140a, and the lid portion 150a is not reduced compared to the fixing strength when initially used.

[0059] In addition, in the first embodiment, the number of times of use of the first housing 130a, the second housing 140a, and the lid portion 150a in their respective reuses corresponds to the protrusions among the multiple protrusions CP10a to CP60a, CP10aB to CP60aB that are used in their respective reuses. Therefore, the number of times of use of the first housing 130a, the second housing 140a, and the lid portion 150a can be easily known from the structure of the liquid storage container 100a as a finished product.

[0060] The first housing 130a and the lid portion 150a in this embodiment are also referred to as "a pair of components". The second housing 140a and the lid portion 150a are also referred to as "a pair of components". The protrusions CP30a to CP60a and the protrusions CP30aB to CP60aB are also referred to as "riveting pins".

[0061] B. Second Embodiment:

[0062] Figure 5This is a perspective view of the liquid container 100b showing the second embodiment. Figure 6 This is an exploded perspective view of the liquid container 100b showing the second embodiment. Most parts of the structure of the liquid container 100b in the second embodiment are common to the structure of the liquid container 100a in the first embodiment. Hereinafter, the points of the structure of the liquid container 100b that are different from the structure of the liquid container 100a will be described. The points of the structure of the liquid container 100b that are not described below are the same as the structure of the liquid container 100a. For the structures in the liquid container 100b that correspond to the structures in the liquid container 100a, the reference numerals are indicated in the respective figures by replacing the "a" at the end of the reference numerals of the corresponding structures in the liquid container 100a with "b".

[0063] In the liquid container 100b, the first wall 131b of the first housing 130b has two holes CPH10b and CPH40b instead of six holes CPH10a to CPH60a. The holes CPH10b and CPH40b are arranged along the long side of the two long sides of the first wall 131b that is not connected to the fourth wall 134b. In Figure 6 the holes CPH10b and CPH40b are arranged in the X-axis direction. The holes CPH10b and CPH40b penetrate the first wall 131b in a direction perpendicular to the first wall 131b. The holes CPH10b and CPH40b have counterbores around the openings on the side of the surface of the outer shell 100Sb in the first wall 131b. The counterbores receive the flanges of the riveting pins CPl0b and CP40b.

[0064] The second wall 132b of the first housing 130b has a hole 136b (see Figure 5 and Figure 6 ). The hole 136b is provided at a position close to the long side of the two long sides of the second wall 132b that is connected to the first wall 131b, and is provided near the short side of the two short sides of the second wall 132b that is not connected to the fourth wall 134b. The hole 136b penetrates the second wall 132b in a direction perpendicular to the second wall 132b. The shape of the opening of the hole 136b is a substantially rectangular shape with the length direction parallel to the two long sides of the second wall 132b. In Figure 6 the hole 136b is arranged in the Y-axis direction.

[0065] The third wall 133b of the first housing 130b has a hole 137b (see Figure 6)。The hole 137b is provided at a position near the long side of the third wall 133b that is connected to the first wall 131b among the two long sides, and is provided near the short side of the third wall 133b that is not connected to the fourth wall 134b. The hole 137b penetrates the third wall 133b in a direction perpendicular to the third wall 133b. The shape of the opening of the hole 137b is a substantially rectangular shape with the longitudinal direction parallel to the two long sides of the third wall 133b. In Figure 6 the hole 137b is arranged along the Y-axis direction.

[0066] In the state where the liquid containing container 100b is formed, the second housing 140b has a shape that is substantially symmetric with respect to a plane parallel to the XY plane and the first housing 130b (refer to Figure 5 and Figure 6 ).

[0067] The first wall 141b of the second housing 140b has holes CPH10bB and CPH40bB. In the state where the liquid containing container 100b is formed, the hole CPH10bB has a shape that is symmetric with respect to a plane parallel to the XY plane and the hole CPH10b of the first housing 130b. In the state where the liquid containing container 100b is formed, the hole CPH40bB has a shape that is symmetric with respect to a plane parallel to the XY plane and the hole CPH40b of the first housing 130b.

In the state where the liquid containing container 100b is formed, the hole 149b has a shape that is symmetric with respect to a plane parallel to the XY plane and the hole 137b of the first housing 130b. In Figure 5 and Figure 6 the third wall 143b of the second housing 140b and the hole 149b are not shown.

[0069] In the liquid containing container 100b, the fourth wall 154b of the lid portion 150b has two holes CPH70b and CPH80b instead of six protrusions CP10a to CP60a (refer to Figure 6 ). The holes CPH70b and CPH80b are arranged along the long side of the fourth wall 154b that is not connected to the first wall 151b. In Figure 6Among them, the holes CPH70b and CPH80b are arranged along the X-axis direction. The holes CPH70b and CPH80b penetrate the fourth wall 154b in a direction perpendicular to the fourth wall 154b.

[0070] The fifth wall 155b has a shape that is substantially symmetric with respect to a plane parallel to the XY plane and the fourth wall 154b. The fifth wall 155b of the cover portion 150b has two holes CPH70bB and CPH80bB instead of six protrusions CP10aB to CP60aB. The hole CPH70bB has a shape that is symmetric with respect to a plane parallel to the XY plane and the hole CPH70b of the fourth wall 154b. The hole CPH80bB has a shape that is symmetric with respect to a plane parallel to the XY plane and the hole CPH80b of the fourth wall 154b. In Figure 5 and Figure 6 Among them, the fifth wall 155b and the two holes CPH70bB and CPH80bB are not shown.

[0071] The second wall 152b of the cover portion 150b has holes 160b and 158b (see Figure 6 ). The holes 160b and 158b are arranged in the order of the holes 160b and 158b along the short side of the two short sides of the second wall 152b that is not connected to the first wall 151b. In Figure 6 Among them, the holes 160b and 158b are arranged along the Z-axis direction. The holes 160b and 158b penetrate the second wall 152b in a direction perpendicular to the second wall 152b. The shape of the openings of the holes 160b and 158b is a substantially rectangular shape whose length direction is parallel to the two long sides of the second wall 152b. In Figure 6 Among them, the holes 160b and 158b are respectively arranged along the Y-axis direction.

[0072] The third wall 153b has a shape that is substantially symmetric with respect to a plane parallel to the YZ plane and the second wall 152b.

In Figure 5 and Figure 6 Among them, the third wall 153b and the holes 157b and 159b are not shown.

[0073] When observing the first housing 130b, the second housing 140b, and the cover portion 150b that are assembled to each other along the Z-axis direction, the hole CPH10b of the first housing 130b, the hole CPH70b of the cover portion 150b, the hole CPH70bB of the cover portion 150b, and the hole CPH10bB of the second housing 140b coincide with each other (see Figure 6 ).

[0074] When observing the mutually assembled first housing 130b, second housing 140b, and lid portion 150b in the Z-axis direction, the hole CPH40b of the first housing 130b, the hole CPH80b of the lid portion 150b, the hole CPH80bB of the lid portion 150b, and the hole CPH40bB of the second housing 140b coincide with each other (refer to Figure 6 ).

[0075] When observing the mutually assembled first housing 130b, second housing 140b, and lid portion 150b in the negative X-axis direction, the hole 136b of the first housing 130b and the hole 160b of the lid portion 150b coincide with each other (refer to Figure 6 ). The hole 148b of the second housing 140b and the hole 158b of the lid portion 150b coincide with each other.

[0076] Similarly, when observing the mutually assembled first housing 130b, second housing 140b, and lid portion 150b in the positive X-axis direction, the hole 137b of the first housing 130b and the hole 157b of the lid portion 150b coincide with each other. The hole 149B of the second housing 140b and the hole 159b of the lid portion 150b coincide with each other.

[0077] The liquid storage container 100b includes riveting pins CP10b and CP40b. The riveting pins CP10b and CP40b are rod-shaped members each having a flange at one end. Different from the protrusions CP10a to CP60a, CP10aB to CP60aB of the first embodiment, the riveting pins CP10b and CP40b are members separate from the first housing 130b and the second housing 140b.

[0078] Figure 7 is a top view of the liquid storage container 100b. Figure 8 is a side view of the liquid storage container 100b. Figure 9 is Figure 7 a cross-sectional view taken along line IX-IX in

[0079] When the first housing 130b, second housing 140b, and lid portion 150b are assembled, the riveting pin CP10b passes through the mutually coinciding hole CPH10b of the first housing 130b, the hole CPH70b of the lid portion 150b, the hole CPH70bB of the lid portion 150b, and the hole CPH10bB of the second housing 140b (refer to Figure 6 and Figure 7 ). The riveting pin CP40b passes through the mutually coinciding hole CPH40b of the first housing 130b, the hole CPH80b of the lid portion 150b, the hole CPH80bB of the lid portion 150b, and the hole CPH40bB of the second housing 140b (refer to Figure 9 ,Figure 6 and Figure 7 ). At this time, the riveting pins CP10b and CP40b do not interfere with the bag portion 110 and the fixing member 120b accommodated in the outer shell 100Sb.

[0080] Then, the tip of the riveting pin CP10b protruding from the hole CPH10bB of the second housing 140b is deformed. The tip of the riveting pin CP10b is enlarged to a size that cannot pass through the hole CPH10bB of the second housing 140b, and a flange is formed. Similarly, the tip of the riveting pin CP40b protruding from the hole CPH40bB of the second housing 140b is deformed. The tip of the riveting pin CP40b is enlarged to a size that cannot pass through the hole CPH40bB of the second housing 140b, and a flange is formed (see Figure 9 ). As a result, the first housing 130b, the second housing 140b, and the lid portion 150b are fixed to each other by the riveting pins CP10b and CP40b.

[0081] That is, in the liquid container 100b as a finished product, the first housing 130b, the second housing 140b, and the lid portion 150b are fixed to each other by two riveting pins CP10b and CP40b (see Figure 9 , Figure 5 and Figure 7 ).

[0082] In the liquid container 100b as a finished product, the riveting pin CP40b can be visually confirmed from the outside through the hole 136b of the first housing 130b and the hole 160b of the lid portion 150b (see Figure 8 and Figure 6 ). In addition, the riveting pin CP40b can be visually confirmed from the outside through the hole 148b of the second housing 140b and the hole 158b of the lid portion 150b (see Figure 8 and Figure 6 ).

[0083] Similarly, the riveting pin CP10b can be visually confirmed from the outside through the hole 137b of the first housing 130b and the hole 157b of the lid portion 150b. In addition, the riveting pin CP10b can be visually confirmed from the outside through the hole 149b of the second housing 140b and the hole 159b of the lid portion 150b.

[0084] After the liquid in the bag portion 110 is consumed, when the fixing member 120b and the bag portion 110 of the liquid container 100b are replaced and the liquid container 100b is reconstituted, the following processing is performed.

[0085] The cutting tool is inserted into the outer housing 100Sb through the hole 137b of the first housing 130b and the hole 157b of the cover part 150b, or through the hole 149b of the second housing 140b and the hole 159b of the cover part 150b, and the riveting pin CP10b is cut off. Similarly, the cutting tool is inserted into the outer housing 100Sb through the hole 136b of the first housing 130b and the hole 160b of the cover part 150b, or through the hole 148b of the second housing 140b and the hole 158b of the cover part 150b, and the riveting pin CP40b is cut off (refer to Figure 8 and Figure 6 ). Then, the riveting pins CP10b and CP40b are removed from the outer housing 100Sb, and the first housing 130b, the second housing 140b, and the cover part 150b are separated from each other.

[0086] In the structure of the second embodiment, the riveting pins CP10b and CP40b can be broken from outside the outer housing 100Sb through the holes provided in the outer housing 100Sb. Therefore, the riveting pins CP10b and CP40b can be easily removed.

[0087] The fixing member 120b and the bag part 110 are taken out, and a new fixing member 120b and a new bag part 110 are installed on the cover part 150b. The first housing 130b and the second housing 140b are assembled while sandwiching the cover part 150b, the fixing member 120b, and the bag part 110.

[0088] A new riveting pin CP10b passes through the hole CPH10b of the first housing 130b, the hole CPH70b of the cover part 150b, the hole CPH70bB of the cover part 150b, and the hole CPH10bB of the second housing 140b that overlap each other (refer to Figure 6 and Figure 7 ). A new riveting pin CP40b passes through the hole CPH40b of the first housing 130b, the hole CPH80b of the cover part 150b, the hole CPH80bB of the cover part 150b, and the hole CPH40bB of the second housing 140b that overlap each other (refer to Figure 9 , Figure 6 and Figure 7 ). The tip of the riveting pin CP10b is enlarged to a size that cannot pass through the hole CPH10bB of the second housing 140b, and a flange is formed. Similarly, the tip of the riveting pin CP40b is enlarged to a size that cannot pass through the hole CPH40bB of the second housing 140b, and a flange is formed (refer to Figure 9 ). As a result, the first housing 130b, the second housing 140b, and the cover part 150b are fixed to each other by the riveting pins CP10b and CP40b.

[0089] With the structure of the second embodiment, when the first housing 130b, the second housing 140b, and the lid portion 150b are reused, the first housing 130b, the second housing 140b, and the lid portion 150b can be fixed by the new riveting pins CP10b and CP40b. Therefore, when the first housing 130b, the second housing 140b, and the lid portion 150b are reused, the liquid storage container 100b can be configured in such a way that the fixing strength is not reduced compared to the initial use.

[0090] According to the second embodiment, the first housing 130b, the second housing 140b, and the lid portion 150b can be reused regardless of the number of times the riveting pins CP10b and CP40b are damaged for the reconstitution of the liquid storage container 100b.

[0091] In the second embodiment, since the riveting pins CP10b and CP40b are replaced during the reconstitution of the liquid storage container 100b, they can also be deformed and damaged during the disassembly of the first housing 130b, the second housing 140b, and the lid portion 150b. On the other hand, since the first housing 130b, the second housing 140b, and the lid portion 150b are reused during the reconstitution of the liquid storage container 100b, it is preferable that they are not deformed during disassembly. In this way, in the second embodiment, the role distribution among the riveting pins CP10b and CP40b, the first housing 130b, the second housing 140b, and the lid portion 150b is clear. Therefore, the design of the engaging portions among the riveting pins CP10b and CP40b, the first housing 130b, the second housing 140b, and the lid portion 150b is relatively easy.

[0092] The first housing 130b and the lid portion 150b in this embodiment are also referred to as "a pair of components". The second housing 140b and the lid portion 150b are also referred to as "a pair of components".

[0093] C. Third Embodiment:

[0094] Figure 10 It is a perspective view showing the liquid storage container 100c of the third embodiment. Figure 11FIG. is an exploded perspective view of the liquid container 100c showing the third embodiment. Most of the structure of the liquid container 100c in the third embodiment is common to the structure of the liquid container 100b in the second embodiment. Hereinafter, the differences between the structure of the liquid container 100c and the structure of the liquid container 100b will be described. The points not described below in the structure of the liquid container 100c are the same as the structure of the liquid container 100b. For the structures in the liquid container 100c corresponding to the structures in the liquid container 100b, the reference numerals are indicated in the respective figures by replacing the "b" at the end of the reference numeral of the corresponding structure of the liquid container 100b with "c".

[0095] The first housing 130c of the liquid container 100c includes a fifth wall 135c in addition to the first wall 131c, the second wall 132c, the third wall 133c, and the fourth wall 134c. The fifth wall 135c is a substantially rectangular flat plate portion parallel to the ZX plane. The fifth wall 135c is a flat plate portion extending in a direction perpendicular to the first wall 131c from one short side of the first wall 131c. The fifth wall 135c faces the fourth wall 134c. One short side of the fifth wall 135c is connected to one short side of the second wall 132c. The other short side of the fifth wall 135c is connected to one short side of the third wall 133c. The fifth wall 135c is formed thicker than the second wall 132c, the third wall 133c, and the fourth wall 134c.

[0096] The first wall 131c of the first housing 130c has two holes CPH10c, CPH40c. The holes CPH10c, CPH40c are through holes penetrating the first wall 131c in a direction parallel to the two short sides of the fifth wall 135c. In Figure 11 , the holes CPH10c, CPH40c penetrate the first wall 131c in the Z-axis direction. In Figure 11 , the holes CPH10c, CPH40c are arranged along the X-axis direction. One end of the holes CPH10c, CPH40c opens on the same surface of the first wall 131c as the surface constituting the outer shell 100Sc. The holes CPH10c, CPH40c have counterbores around the opening (see Figure 11 ). The counterbores receive the flanges of the riveting pins CP10c, CP40c.

[0097] The fifth wall 135c also has a hole 138c. The hole 138c is a through hole that penetrates the fifth wall 135c in a direction perpendicular to the fifth wall 135c. The hole 138c is provided at a position close to the long side of the two long sides of the fifth wall 135c that is connected to the first wall 131c. The shape of the opening of the hole 138c is a substantially rectangular shape with its longitudinal direction parallel to the two long sides of the fifth wall 135c. In Figure 10 and Figure 11 , the hole 138c is arranged in the X-axis direction. In the X-axis direction, the hole 138c is provided within a range that includes the positions where the holes CPH10c and CPH40c are provided. As a result, within the fifth wall 135c, the holes CPH10c and CPH40c intersect with the hole 138c.

[0098] The fifth wall 135c also has a recess 139c. The recess 139c is arranged approximately at the center of the long side of the two long sides of the fifth wall 135c that is not connected to the first wall 131c. The recess 139c is a groove portion that penetrates the fifth wall 135c in a direction perpendicular to the fifth wall 135c. The recess 139c has a semi-circular concave shape.

[0099] In addition to having the first wall 141c, the second wall 142c, the third wall 143c, and the fourth wall 144c, the second housing 140c also has a fifth wall 145c (see Figure 11 ). The fifth wall 145c has holes CPH10cB, CPH40cB, a hole 148c, and a recess 149c. In a state where the liquid storage container 100c is formed, the second housing 140c has a shape that is substantially symmetric with respect to a plane parallel to the XY plane and the first housing 130c.

[0100] In a state where the liquid storage container 100c is formed, the CPH10cB and CPH40cB of the second housing 140c have a shape that is symmetric with respect to a plane parallel to the XY plane and the holes CPH10c and CPH40c of the first housing 130c. In a state where the liquid storage container 100c is formed, the hole 148c of the second housing 140c has a shape that is symmetric with respect to a plane parallel to the XY plane and the hole 138c of the first housing 130c.

[0101] When the mutually assembled first housing 130c and second housing 140c are viewed in the Z-axis direction, the hole CPH10c of the first housing 130c coincides with the hole CPH10cB of the second housing 140c (see Figure 11 ). When the mutually assembled first housing 130c and second housing 140c are viewed in the Z-axis direction, the hole CPH40c of the first housing 130c coincides with the hole CPH40cB of the second housing 140c.

[0102] In a state where the liquid storage container 100c is formed, the concave portion 149c of the second housing 140c has a shape symmetric to the concave portion 139c of the first housing 130c with respect to a plane parallel to the XY plane.

[0103] In a state where the liquid storage container 100c is formed, the concave portion 139c of the fifth wall 135c of the first housing 130c and the concave portion 149c of the fifth wall 145c of the second housing 140c form a hole penetrating the outer housing 100Sc. The fixing member 120c is fixed to the first housing 130c and the second housing 140c in a state where a part of the fixing member 120c is disposed in this hole. As a result, the bag portion 110 is fixed to the outer housing 100Sc. The liquid flow path of the fixing member 120c passes through the inside of this hole and communicates with the outside (see Figure 10 ). In Figure 10 , the end of the liquid flow path of the fixing member 120c is sealed with a rectangular film.

[0104] The fixing member 120c has two riveting pins CP10c and CP40c (see Figure 11 ). The riveting pins CP10c and CP40c are rod-shaped members that extend in a direction perpendicular to the direction of the liquid flow path communicating with the inside of the bag portion 110 in the fixing member 120c. In Figure 11 , the riveting pins CP10c and CP40c extend in both the positive Z-axis direction and the negative Z-axis direction. The riveting pins CP10c and CP40c are disposed on both sides of the liquid flow path.

[0105] Figure 12 is a front view of the liquid storage container 100c. Figure 13 is a top view of the liquid storage container 100c. Figure 14 is Figure 13 a sectional view taken along line XIV-XIV in

[0106] When the first housing 130c and the second housing 140c are assembled, the riveting pin CP10c of the fixing member 120c passes through the hole CPH10c of the first housing 130c and the hole CPH10cB of the second housing 140c that overlap each other. The riveting pin CP40c of the fixing member 120c passes through the hole CPH40c of the first housing 130c and the hole CPH40cB of the second housing 140c that overlap each other (see Figure 14 and Figure 11 ).

[0107] Figure 15 is a perspective view showing the fixing member 120c and the bag portion 110 before being loaded into the liquid storage container 100c. Figure 16It is a perspective view of the fixing member 120c and the bag portion 110 in which the riveting pins CP10c and CP40c are deformed after being loaded into the liquid storage container 100c.

[0108] After the riveting pin CP10c passes through the hole CPH10c of the first housing 130c, the tip of the riveting pin CP10c protruding from the hole CPH10c is deformed. The tip of the riveting pin CP10c is enlarged to a size that cannot pass through the hole CPH10cB of the second housing 140c, and a flange is formed (see Figure 14 and Figure 16 ).

[0109] Similarly, the tip of the riveting pin CP10c protruding from the hole CPH10cB of the second housing 140c is deformed. The tip of the riveting pin CP40c protruding from the hole CPH40c of the first housing 130c is deformed. The tip of the riveting pin CP40c protruding from the hole CPH40cB of the second housing 140c is deformed. As a result, the first housing 130c and the second housing 140c are fixed to each other by the riveting pins CP10c and CP40c (see Figure 10 , Figure 13 and Figure 14 ).

[0110] That is, in the liquid storage container 100c as a finished product, the first housing 130c and the second housing 140c are fixed to each other by the riveting pins CP10c and CP40c of the fixing member 120c (see Figure 14 and Figure 10 ).

[0111] In the liquid storage container 100c as a finished product, the riveting pins CP10c and CP40c can be visually confirmed from the outside through the hole 138c of the first housing 130c and the hole 148c of the second housing 140c (see Figure 12 ).

[0112] After the liquid in the bag portion 110 is consumed, when the fixing member 120c and the bag portion 110 of the liquid storage container 100c are replaced and the liquid storage container 100c is reconstituted, the following processing is performed.

[0113] The cutting tool is inserted into the outer shell 100Sc through the hole 138c of the first housing 130c or through the hole 148c of the second housing 140c, and the riveting pins CP10c and CP40c are cut (see Figure 12 ). Then, the riveting pins CP10c and CP40c are removed from the outer shell 100Sc, and the first housing 130c and the second housing 140c are separated from each other.

[0114] In the structure of the third embodiment, the riveting pins CP10c and CP40c can be broken from outside the housing 100Sc through the holes provided in the housing 100Sc. Therefore, the riveting pins CP10c and CP40c can be easily removed.

[0115] The fixing member 120c and the bag portion 110 are taken out, and a new fixing member 120c and a bag portion 110 are installed on the first housing 130c or the second housing 140c. The first housing 130c and the second housing 140c are assembled while sandwiching the fixing member 120c and the bag portion 110.

[0116] The riveting pin CP10c of the new fixing member 120c passes through the hole CPH10c of the first housing 130c and the hole CPH10cB of the second housing 140c that coincide with each other. The riveting pin CP40c of the new fixing member 120c passes through the hole CPH40c of the first housing 130c and the hole CPH40cB of the second housing 140c that coincide with each other. The subsequent processing is the same as when the liquid storage container 100c was initially constructed.

[0117] According to the third embodiment, when the liquid storage container 100c is reused, the liquid storage container 100c can be easily re-constructed by replacing the bag portion 110 and the fixing member 120c having the riveting pins CP10c and CP40c.

[0118] The first housing 130c and the second housing 140c in the present embodiment are also referred to as "a pair of members".

[0119] D. Other embodiments:

[0120] D1. First other embodiment:

[0121] (1) In the above first embodiment, the lid portion 150a has protrusions CP10a to CP60a, CP10aB to CP60aB as riveting pins (refer to Figures 2 to 4 ). However, the first housing 130a may have the riveting pins, or the second housing 140a may have the riveting pins. Moreover, the riveting pins may be provided by both the lid portion 150 and the first housing 130a that are fixed to each other. The riveting pins may also be provided by both the lid portion 150 and the second housing 140a that are fixed to each other.

[0130] D5. Other Embodiment 5:

[0131] In the above second embodiment, it is possible to visually confirm the riveting pin CP40b from the outside through the hole 136b of the first housing 130b and the hole 160b of the lid portion 150b (see Figure 8 and Figure 6 ). Further, it is possible to visually confirm the riveting pin CP40b from the outside through the hole 148b of the second housing 140b and the hole 158b of the lid portion 150b (see Figure 8 and Figure 6 ). In the above third embodiment, it is possible to visually confirm the riveting pin CP40b from the outside through the hole 136b of the first housing 130b and the hole 160b of the lid portion 150b (see Figure 8 and Figure 6 ). Further, it is possible to visually confirm the riveting pin CP40b from the outside through the hole 148b of the second housing 140b and the hole 158b of the lid portion 150b (see Figure 8 and Figure 6 ).

[0132] However, the outer shell may also have a hole such that the riveting pin cannot be visually confirmed from the outside, but the riveting pin inside the outer shell can be destroyed by inserting a special tool through the hole. Further, as in the first embodiment, it is also possible to adopt a configuration in which the outer shell does not have a hole capable of destroying the riveting pin inside the outer shell.

[0133] E. Other modes:

[0134] The present invention is not limited to the above embodiments, and can be implemented in various ways without departing from the gist thereof. For example, the present invention can also be implemented in the following manner. In order to solve part or all of the problems of the present invention, or to achieve part or all of the effects of the present invention, the technical features in the above embodiments corresponding to the technical features in each of the following modes can be appropriately replaced or combined. Further, if the technical feature is not described as an essential technical feature in this specification, it can be appropriately deleted.

[0135] (1) According to one mode of the present invention, there is provided a liquid storage container. The liquid storage container includes: a bag portion that stores a liquid; and a pair of members that are reused when replacing the used bag portion and reconstituting the liquid storage container. The pair of members are fixed to each other by one or more riveting pins.

[0136] If the above structure is adopted, even if the temperature of the liquid storage container changes, the plurality of members can be easily separated by destroying the riveting pins and then processed.

[0137] (2) In the liquid storage container of the above-described manner, it is also possible to adopt the following manner: at least one of the pair of members includes a plurality of riveting pins configured to be able to fix the pair of members to each other, and the pair of members are fixed to each other by a part of the plurality of riveting pins.

[0138] If the above-described manner is adopted, when the pair of members are reused, the pair of members can be fixed by the riveting pins that have not been used so far. Therefore, when the pair of members are reused, the liquid storage container can be reconfigured in such a way that the strength of the fixation of the pair of members is not reduced compared to when they are initially used.

[0139] In addition, by making the number of times of use of each member during reuse correspond to the riveting pins used during reuse among the plurality of riveting pins, it is possible to easily know the number of times of use of the pair of members from the structure of the liquid storage container.

[0140] (3) In the liquid storage container of the above-described manner, it is also possible to adopt the following manner: the pair of members and the riveting pins are separate members.

[0141] If the above-described manner is adopted, when the pair of members are reused, the pair of members can be fixed by new riveting pins. Therefore, when the pair of members are reused, the liquid storage container can be configured in such a way that the strength of the fixation of the pair of members is not reduced compared to when they are initially used.

[0142] In addition, the pair of members can be reused regardless of the number of times the riveting pins have been broken so far for the reconfiguration of the liquid storage container.

[0143] Moreover, in the above-described manner, the functions of the riveting pins and the pair of members are clearly defined. Since the riveting pins are replaced during the reconfiguration of the liquid storage container, they can be deformed and broken during the disassembly of the pair of members, and since the pair of members are not replaced during the reconfiguration of the liquid storage container, they are preferably not deformed during disassembly. Therefore, the design of the engaging portion between the riveting pins and the pair of members is relatively easy.

[0144] (4) In the liquid storage container of the above-described manner, it is also possible to adopt the following manner: the pair of members are members that constitute at least a part of the outer shell, the outer shell surrounds the bag portion, the liquid storage container includes a fixing member for fixing the bag portion to the outer shell, and the fixing member includes the riveting pins.

[0145] If the above-described manner is adopted, when the liquid storage container is reused, the liquid storage container can be easily reconfigured by replacing the bag portion and the fixing member including the riveting pins.

[0146] (5) In the liquid storage container of the above-described manner, it is also possible to adopt the following manner: having a housing that surrounds the bag portion, and the housing having a hole through which the riveting pin that fixes the pair of components to each other can be visually confirmed from the outside.

[0147] If the above-described manner is adopted, the riveting pin can be broken from outside the housing via the hole. Therefore, the riveting pin can be easily removed.

[0148] The present invention can also be implemented by various manners of the liquid storage container. For example, it can be implemented by a manufacturing method of the liquid storage container, a computer program that implements its control method, a non-transitory storage medium that stores the computer program, and the like.
