[0009] Hereinafter, an embodiment will be described with reference to the drawings. Note that the same components will be denoted by the same reference numerals. Furthermore, the relative arrangement and shapes of the components described in the embodiment are merely examples.

[0010] First Embodiment (Liquid discharge device) 1 is a perspective view of a liquid ejection device 1 in which a liquid storage container in this embodiment is used. The liquid ejection device 1 is a serial type inkjet recording device, and includes a housing 2 and a liquid tank 3 arranged inside the housing 2. The liquid tank 3 contains ink, which is a liquid to be ejected onto a recording medium (not shown).

[0011] 2 is a perspective view showing an internal configuration of the liquid ejection device 1 shown in FIG. The liquid ejection device 1 includes a transport roller 4 for transporting a recording medium (not shown), a liquid ejection head 5 for ejecting liquid, a carriage 6 on which the liquid ejection head 5 is mounted, and a carriage motor 7 for driving the carriage 6. The liquid ejection device 1 includes a liquid passage 8 disposed between the liquid tank 3 and the liquid ejection head 5. The type of recording medium is not particularly limited as long as an image is formed by the liquid ejected from the liquid ejection head 5. The type of recording medium may be, for example, paper, cloth, an optical disc label surface, a plastic sheet, or an OHP sheet.

[0012] The liquid is stored in the liquid tank 3, supplied to the liquid ejection head 5 via the liquid passage 8, and ejected from the liquid ejection head 5. In this embodiment, for example, four colors of ink (e.g., cyan, magenta, yellow, and black) are used as the liquid. The liquid tank 3 is provided with four liquid tanks 3a to 3d, each of which stores an ink of a respective color. Hereinafter, when identifying and referring to each individual liquid tank, the liquid tanks 3a to 3d etc. will be suffixed with an alphabet, and when referring to any liquid tank, it will be referred to as the liquid tank 3. Each of the four liquid tanks 3a to 3d is disposed at the front part of the liquid ejection device 1 inside the housing 2.

[0013] (Liquid tank) FIG. 3 is an exploded perspective view of the liquid tank 3 of the liquid ejection device 1 shown in FIG. 1. The liquid tank 3 of this embodiment has a liquid tank body 31 for storing liquid, an inlet 32 ​​communicating with a liquid storage chamber in the liquid tank body 31, and a tank lid 33 that can be attached to the liquid tank body 31 so as to cover the inlet 32. The liquid tank 3 has a communication flow path 34 that extends vertically from the inlet 32 ​​into the liquid tank body 31. The communication flow path 34 has a liquid inflow path 34a (see FIG. 4) for inflowing liquid from a liquid storage container 10 described later into the liquid tank 3, and an air outflow path 34b (see FIG. 4) for outflowing air from the liquid tank 3. The liquid inflow path 34a is arranged in parallel with the air outflow path 34b in the liquid tank 3, and extends longer in the vertical direction than the air outflow path 34b. The tip of the liquid inflow path 34a is arranged at a position close to the bottom of the liquid tank 3. After refilling the liquid tank 3 with liquid, in order to prevent evaporation of the liquid from the liquid storage chamber in the liquid tank body 31, the tank lid 33 is attached to the liquid tank body 31 to seal the liquid storage chamber in the liquid tank body 31.

[0014] (Liquid replenishment by gas-liquid exchange) FIG. 4 is an explanatory diagram showing the process of pouring liquid from the liquid storage container 10 into the liquid tank 3 according to this embodiment.

[0015] In this embodiment, the liquid tank 3 is replenished with liquid by removing the tank lid 33 from the liquid tank body 31, and then performing gas-liquid exchange through the liquid storage container 10 from the inlet 32 ​​exposed thereby. In detail, as shown in FIG. 4(a), the liquid tank 3 is empty, and the liquid storage container 10 is in a state in which liquid is stored. Then, the refilling of the liquid tank 3 with liquid is started by connecting the inlet of the liquid storage container 10 to the inlet 32 ​​of the liquid tank 3. Once started, as shown in FIG. 4(b), the liquid in the liquid storage container 10 flows into the liquid tank 3 via the liquid inflow path 34a, while the air in the liquid tank 3 flows out into the liquid storage container 10 via the air outflow path 34b, and the liquid continues to be replenished into the liquid tank 3. As shown in Figure 4(c), when the liquid refilled into the liquid tank 3 reaches the tip of the air outflow path 34b, the tip of the air outflow path 34b in the liquid tank 3 is blocked, and at the same time, the flow of liquid from the liquid storage container 10 into the liquid tank 3 stops.

[0016] In this way, liquid can be replenished into the liquid tank 3 by gas-liquid exchange. In this embodiment, the liquid tank is replenished with liquid by a mechanism of gas-liquid exchange, but this is not limited thereto, and other mechanisms may be used.

[0017] (Liquid storage container) FIG. 5(a) is a side view of the liquid storage container 10 according to this embodiment, and FIG. 5(b) is a top view of the liquid storage container 10. In this embodiment, the liquid storage container 10 shows a configuration having two liquid storage sections. The liquid storage container 10 has a plurality of liquid storage sections 11, 12, an outlet section 20, and a sealing section 21 that seals the outlet section 20. A partition wall 22 is formed in the liquid storage container 10 so as to divide the liquid storage container 10 into two and form the liquid storage sections 11, 12. This makes it possible to prevent the liquids in the liquid storage container 10 from being mixed together. The outlet section 20 is located at the top of the liquid storage container 10 and is formed in a circular shape. The outlet section 20 has outlets 15, 16 that outlet the liquid from the plurality of liquid storage sections 11, 12, respectively. The outlets 15, 16 are provided approximately in the center of the liquid storage container 10. In this embodiment, the spouts 15, 16 are provided approximately in the center of the liquid storage container 10, but are not limited thereto and may be provided at the end. A first surface 19 including a connection surface connecting to the spouts 15, 16 of the liquid storage portions 11, 12 is formed at the top of the liquid storage container 10, i.e., at the top of the two liquid storage portions 11, 12. On the first surface 19, if the arrangement pitch of the midpoints of the points where a center line CC passing through the center of adjacent spouts 15, 16 intersects with the partitions of each liquid storage portion 11, 12 is A and the arrangement pitch of adjacent spouts 15, 16 is B, it is preferable that A / B>1 is satisfied.

[0018] Therefore, the liquid storage container 10 according to this embodiment can be made compact by consolidating the outlets communicating with the multiple liquid storage portions 11, 12 into a single shape, and the sealing portion that seals the outlet can also be made compact, making it possible to reduce the number of materials used in the liquid storage container.

[0019] The liquid storage container 10 may be made of, for example, PE (polyethylene), PP (polypropylene), or other materials. The liquid storage container 10 may also be made of recycled plastic materials.

[0020] In this embodiment, the sealing portion 21 is formed in a lid shape, but is not limited to this and may be in a film shape. In the case of a film shape, it is possible to further reduce the number of materials used in the liquid storage container 10. In addition, by making the arrangement pitch B of the pouring outlets 15, 16 in this embodiment the same as the arrangement pitch of the injection ports 32 of the multiple liquid tanks 3, it is possible to simultaneously refill two liquid tanks with liquid.

[0021] <Variation 1> Modification 1 of the first embodiment of the present disclosure will be described. Descriptions of the basic configuration of the present disclosure and the same functions and configurations as those of the first embodiment will be omitted, and only differences will be described.

[0022] Generally, liquid ejection devices are often used for full-color recording, and liquid tanks for storing cyan, magenta, and yellow liquids may be arranged in a straight line. In this case, the liquid storage container 10 in Fig. 5 can store only two inks, and there is a risk that three inks cannot be replenished at the same time. Therefore, in order to replenish three inks at the same time, in Modification 1, a liquid storage container in which three liquid storage sections are formed will be described.

[0023] FIG. 6(a) is a side view of the liquid storage container 10a according to the present embodiment, and FIG. 6(b) is a top view of the liquid storage container 10a. In the first modification, the liquid storage container 10a has three liquid storage sections. The liquid storage container 10a has three liquid storage sections 11a, 12a, and 13a, and a sealing section 21a that seals the pouring section 20a. The liquid storage container 10a has partition walls 22a and 23a that divide the liquid storage container 10a into three and form the liquid storage sections 11a, 12a, and 13a. The pouring section 20a is located at the top of the liquid storage container 10a and is formed in a rectangular shape across the liquid storage sections 11a, 12a, and 13a. The pouring section 20a has pouring outlets 15a, 16a, and 17a that pour liquid from the three liquid storage sections 11a, 12a, and 13a, respectively. The outlets 15a, 16a, and 17a are provided in a straight line at approximately the center of the liquid storage container 10a. A first surface 19a is formed on the upper portion of the liquid storage container 10a, i.e., the three liquid storage portions 11a, 12a, and 13a, including a connection surface that connects the outlets 15a, 16a, and 17a of the liquid storage portions 11a, 12a, and 13a. If the arrangement pitch of the midpoints of the points where the center lines CC of the three adjacent outlets 15a, 16a, and 17a intersect with the partitions of the liquid storage portions 11a and 12a on the first surface 19a is A, and the arrangement pitch of the adjacent outlets 15a and 16a is B, it is preferable that A / B>1 is satisfied. On the other hand, the arrangement pitch of the midpoints of the points where the center lines CC of the three adjacent outlets 15a, 16a, and 17a intersect with the partitions of the liquid storage portions 12a and 13a on the first surface 19a is A. If the arrangement pitch of adjacent pouring outlets 16a, 17a is B, it is preferable that A / B>1 be satisfied.

[0024] Therefore, the liquid storage container 10 according to this embodiment can be made compact by consolidating the outlets communicating with the multiple liquid storage portions 11, 12 into a single shape, and the sealing portion that seals the outlet can also be made compact, making it possible to reduce the number of materials used in the liquid storage container.

[0025] <Variation 2> Modification 2 of the first embodiment of the present disclosure will be described. Descriptions of the basic configuration of the present disclosure and functions and configurations similar to those of the first embodiment will be omitted, and differences will be described.

[0026] In the liquid storage container of Modification 1, the liquid storage portions 11a, 12a, and 13a are arranged in a straight line. However, liquid tanks are not always arranged in a straight line, and may be arranged in a circular shape. Therefore, in Modification 2, a liquid storage container in which three liquid storage portions are formed in a circular shape to match the arrangement of the liquid tanks will be described.

[0027] FIG. 7(a) is a side view of the liquid storage container 10b according to the present embodiment, and FIG. 7(b) is a top view of the liquid storage container 10b. In the second modification, the liquid storage container 10b has three liquid storage sections in a circular shape. The liquid storage container 10b has three liquid storage sections 11b, 12b, and 13b, and a sealing section 21b that seals the pouring section 20b. The liquid storage container 10b is formed with partition walls 22b, 23b, and 24b so as to divide the liquid storage container 10b into three sectors and form the liquid storage sections 11b, 12b, and 13b. The pouring section 20b is located at the top of the liquid storage container 10b, and is formed in a circular shape across the liquid storage sections 11b, 12b, and 13b. The spouting section 20b has spouts 15b, 16b, and 17b for spouting liquid from the three liquid storage sections 11b, 12b, and 13b, respectively. The spouts 15b, 16b, and 17b are provided in a circular shape at approximately the center of the liquid storage container 10b. A first surface 19b is formed on the upper part of the liquid storage container 10b, i.e., on the upper part of the three liquid storage sections 11b, 12b, and 13b, and includes a connection surface that connects to the spouts 15b, 16b, and 17b of the liquid storage sections 11b, 12b, and 13b. On the first surface 19b, the arrangement pitch of the midpoints of the points where the center lines of any two of the three adjacent spouts 15b, 16b, and 17b intersect with the partitions of the liquid storage section of the two spouts is defined as A. If the arrangement pitch of the two adjacent spouts is defined as B, it is preferable that A / B>1 is satisfied. In detail, the arrangement pitch of the midpoints of the points where the center lines CC of two adjacent spouts 15b, 16b intersect with the partitions of the liquid storage portions 11b, 12b is defined as A. Then, the arrangement pitch of the adjacent spouts 15b, 16b is defined as B, and it is preferable that A / B>1 is satisfied. Similarly, the arrangement pitch of the midpoints of the points where the center lines (not shown) of two adjacent spouts 16b, 17b intersect with the partitions of the liquid storage portions 12b, 13b is defined as A, and the arrangement pitch of the adjacent spouts 16b, 17b is defined as B, and it is preferable that A / B>1 is satisfied. Similarly, the arrangement pitch of the midpoints of the points where the center lines (not shown) of two adjacent spouts 15b, 17b intersect with the partitions of the liquid storage portions 11b, 13b is defined as A, and the arrangement pitch of the adjacent spouts 15b, 17b is defined as B, and it is preferable that A / B>1 is satisfied.

[0028] Therefore, in the liquid storage container 10b according to this embodiment, the outlets communicating with the multiple liquid storage portions 11b, 12b, and 13b can be integrated into one shape to reduce the size, and the sealing portion that seals the outlet can also be reduced in size, making it possible to reduce the number of materials used in the liquid storage container.

[0029] <Modification 3> Modification 3 of the first embodiment of the present disclosure will be described. Descriptions of the basic configuration of the present disclosure and functions and configurations similar to those of the first embodiment will be omitted, and differences will be described.

[0030] In the liquid storage container of Modification 1, the liquid storage portions 11a, 12a, and 13a are arranged in a straight line. However, liquid tanks are not always arranged in a straight line, and may be arranged in a rectangular shape. Therefore, in Modification 3, a liquid storage container in which three liquid storage portions are formed in a rectangular shape to match the arrangement of the liquid tanks will be described.

[0031] FIG. 8(a) is a side view of the liquid storage container 10c according to the present embodiment, and FIG. 8(b) is a top view of the liquid storage container 10c. In the third modification, the liquid storage container 10c has three liquid storage sections in a rectangular shape. The liquid storage container 10c has three liquid storage sections 11c, 12c, and 13c, and a sealing section 21c that seals the pouring section 20c. The liquid storage container 10c has partition walls 22c, 23c, and 24c formed to divide the liquid storage container 10c into three rectangular parts and form the liquid storage sections 11c, 12c, and 13c. The liquid storage section 11c is formed by the partition wall 22c and the partition wall 24c so as to divide the liquid storage container 10c into two equal parts. In addition, the liquid storage section 12c and the liquid storage section 13c are formed so that one side of the liquid storage section 11c is divided into two equal parts by the partition wall 23c. The outlet 20c is located at the top of the liquid storage container 10c and is formed in a circular shape across the liquid storage portions 11c, 12c, and 13c. The outlet 20c has outlets 15c, 16c, and 17c for pouring liquid from the three liquid storage portions 11c, 12c, and 13c, respectively. The outlets 15c, 16c, and 17c are provided at approximately the center of the liquid storage container 10c. A first surface 19c including a connection surface that connects to the outlets 15c, 16c, and 17c of the liquid storage portions 11c, 12c, and 13c is formed at the top of the liquid storage container 10c, i.e., at the top of the three liquid storage portions 11c, 12c, and 13c. On the first surface 19c, if the arrangement pitch of the midpoints of the points where the center lines CC of three adjacent pouring outlets 15c, 16c intersect with the compartments of the liquid storage sections 11c, 12c is A, and the arrangement pitch of adjacent pouring outlets 15c, 16c is B, it is preferable that A / B>1 is satisfied.

[0032] In this way, by storing the liquid that is consumed in large quantities in a liquid storage section with a large volume, it becomes possible to replenish the liquids, including the liquid that is consumed in large quantities, all at once.

[0033] <Variation 4> Modification 4 of the first embodiment of the present disclosure will be described. Descriptions of the basic configuration of the present disclosure and functions and configurations similar to those of the first embodiment will be omitted, and differences will be described.

[0034] In a liquid ejection device, generally, liquid tanks for storing, for example, cyan, magenta, yellow, and black liquids are arranged close to each other for full color recording. In Modification 4, a liquid storage container in which four liquid storage portions are formed in order to replenish the liquid tank with four inks will be described.

[0035] FIG. 9(a) is a side view of the liquid storage container 10d according to the present embodiment, and FIG. 9(b) is a top view of the liquid storage container 10d. In the fourth modification, the liquid storage container 10d is configured to have four liquid storage sections in a rectangular shape. The liquid storage container 10d has four liquid storage sections 11d, 12d, 13d, and 14d, and a sealing section 21d that seals the pouring section 20d. The liquid storage container 10d is formed with partition walls 22d, 23d, 24d, and 25d so as to divide the liquid storage container 10d into four rectangular sections and form the liquid storage sections 11d, 12d, 13d, and 14d. The liquid storage section 11d is formed by the partition wall 22d and the partition wall 25d. The liquid storage section 12d is formed by the partition wall 22d and the partition wall 23d. Furthermore, liquid storage section 13d is formed by partitions 23d and 24d. Furthermore, liquid storage section 14d is formed by partitions 24d and 25d. Spout section 20d is located at the top of liquid storage container 10d and is formed in a circular shape across liquid storage sections 11d, 12d, 13d, and 14d. Spout section 20d has spouts 15d, 16d, 17d, and 18d for spouting liquid from four liquid storage sections 11d, 12d, 13d, and 14d, respectively. Spouts 15d, 16d, 17d, and 18d are provided approximately in the center of liquid storage container 10d. A first surface 19d is formed on the upper portion of liquid storage container 10d, i.e., on the upper portions of four liquid storage portions 11d, 12d, 13d, 14d, and includes connection surfaces that connect to spouts 15d, 16d, 17d, 18d of liquid storage portions 11d, 12d, 13d, 14d. On first surface 19d, if the arrangement pitch of the midpoints of the points where center lines CC of two adjacent spouts 15d, 16d intersect with the partitions of liquid storage portions 11d, 12d is A, and the arrangement pitch of adjacent spouts 15d, 16d is B, then it is preferable that A / B>1 be satisfied.

[0036] The liquid storage container according to the present disclosure can inject multiple liquids at once using multiple liquid storage sections and outlets that communicate with the multiple liquid storage sections, thereby improving the convenience for users when refilling ink. In this case, even if the liquid is injected at once, the refilling can be automatically stopped when the container is full due to the above-mentioned gas-liquid exchange, so that the required amount of liquid can be injected without worrying about liquid overflow.

[0037] As described above, the liquid storage container according to the present disclosure has a plurality of liquid storage sections that store liquid, and a plurality of liquid outlets that respectively pour liquid from the plurality of liquid storage sections. In a first surface of the plurality of liquid storage sections, including a connection surface that connects to the liquid outlet of the liquid storage section, an arrangement pitch of midpoints of points where center lines passing through centers of adjacent liquid outlets intersect with partitions of each of the liquid storage sections is A, and an arrangement pitch of adjacent liquid outlets is B. The relationship between the arrangement pitch A and the arrangement pitch B satisfies A / B>1. Thus, it is possible to provide a liquid storage container that enables the reduction of the number of components used in the liquid storage container by sharing and miniaturizing the components of the liquid storage container.

[0038] <Second embodiment> A second embodiment according to the present disclosure will be described below. Note that descriptions of parts that overlap with the first embodiment will be omitted.

[0039] In the liquid storage container 10 according to the second embodiment, a first surface 19 is formed as a surface including a connection surface with the liquid outlet of the liquid storage portion. In the liquid storage container 10, the arrangement pitch of the midpoints of the points where the center line CC passing through the center of the adjacent liquid outlets 15 and 16 intersects with the partitions of each liquid storage portion is A, and the arrangement pitch of the adjacent liquid outlets is B. In this case, A / B>1 and further A / B<2. It is preferable that the ratio of the arrangement pitch A to the arrangement pitch B is A / B<2 because it is within a range in which the liquid storage portion does not become too large. In addition, it is preferable because it is within a range in which the outlets are not too close to each other, so that it is possible to prevent the ink from mixing between the adjacent outlets. Note that the liquid storage container 10 is molded in the same manner as in the first embodiment, and therefore it is possible to prevent the liquid from overflowing when the liquid is poured out in the same manner as in the first embodiment.

[0040] It is preferable to provide partitions between the respective outlets, since this can prevent the liquids from mixing between the respective outlets. It is more preferable that the partitions are higher than the height of the respective outlets.

[0041] As shown in FIG. 10, a member 29 for defining the arrangement of the spouts may be disposed in the collective spouting portions 20, 20a, 20b, 20c, and 20d. By attaching the liquid storage container 10 in an orientation in which the member 29 for defining the arrangement of the spouts fits into a member (not shown) for defining the arrangement on the liquid tank 3 side, it is possible to prevent a different liquid from being refilled into the liquid tank when refilling the liquid. In the second embodiment, the shape of the member 29 for defining the arrangement of the spouts is shown as a rectangle as an example, but it may be of another shape. According to this embodiment, in a liquid storage container having a plurality of liquid storage containers, at least one member 29 for defining the arrangement of the spouts is required, so that it is possible to reduce the number of components of the liquid storage container.

[0042] As described above, according to the present disclosure, in a liquid container capable of refilling a printer with a plurality of liquids at once, it is possible to prevent liquid overflow during liquid refill. Also, it is possible to prevent a liquid tank from being refilled with a different liquid during liquid refill. Also, it is possible to provide a liquid container that allows the number of components used in the liquid container to be reduced by sharing and miniaturizing the components of the liquid container. In other words, it is possible to reduce the amount of discarded components. Since the components of the liquid container contain plastic, reducing the number of discarded components means, in other words, reducing the amount of discarded plastic. Therefore, the technology described in this specification can contribute to the realization of a sustainable society such as a carbon-free / recycling-based society.

[0043] <Other embodiments> The present disclosure includes configurations typified by the following liquid ejection head examples.

[0044] <Configuration 1> A liquid storage container comprising a plurality of liquid storage sections for storing liquid, and a plurality of outlets for pouring liquid from each of the plurality of liquid storage sections, wherein, on a first surface of the plurality of liquid storage sections including a connection surface connecting to the outlets of the liquid storage sections, an arrangement pitch of midpoints of points where center lines passing through the centers of adjacent outlets intersect with partitions of each of the liquid storage sections is A, and an arrangement pitch of adjacent liquid outlets is B, where A / B>1 is satisfied.
