Description

Technical Field

[0001] The present disclosure relates to a liquid storage container and a liquid ejecting apparatus, and particularly to a liquid storage container including a plurality of liquid storage portions. Background Art

[0002] There is a liquid tank that can be refilled with liquid, which is used in a liquid ejecting device such as an inkjet printing device. For example, the use of a liquid storage container including an outlet for dispensing liquid makes it possible to refill the liquid tank with liquid from the liquid storage container through the outlet. Japanese Patent Laid-Open No. 6-226991 (referred to as Document 1) discloses a flexible ink tank having a sealing structure, the flexible ink tank including a plurality of ink storage portions, wherein an ink tank body is formed by laminating a flexible film having a low gas permeability into a plurality of layers.

[0003] However, in Document 1, the difference between the distance between the approximate centers of adjacent liquid storage parts and the distance between their outlets on the surface including the connection surface connected to the outlet of the liquid storage part is small. Therefore, in the case where the number of liquid storage parts is increased, there is a concern that the increase will lead to an increase in the size or number of components around the outlet and an increase in the number of discarded components.

[0004] An object of the present disclosure is to provide a liquid storage container which can suppress an increase in the size of components around an outlet of the liquid storage container, and a liquid ejecting apparatus using the liquid storage container. Summary of the invention

[0005] A liquid storage container according to one aspect of the present disclosure includes: a plurality of liquid storage parts, which store liquid; and a plurality of outlets, through which the liquid is respectively dispensed from the plurality of liquid storage parts, wherein, on a first surface of the plurality of liquid storage parts including a connecting surface connected to the outlets of the liquid storage parts, A / B > 1 is satisfied, wherein the arrangement spacing between the midpoints of the points where a center line passing through the centers of adjacent outlets intersects with an area of ​​the liquid storage part is A, and the arrangement spacing between the adjacent outlets is B.

[0017] The following describes the embodiments with reference to the accompanying drawings. Note that the same configuration is described using the same reference numerals. In addition, the relative arrangement, shape, etc. of the components described in the embodiments are merely examples.

[0018] <First Embodiment>

[0019] (Liquid Injection Equipment)

[0020] Figure 1 1 is a perspective view of a liquid ejection device 1 using a liquid storage container in this embodiment. The liquid ejection device 1 is a tandem inkjet printing device and includes a housing 2 and a liquid tank 3 arranged inside the housing 2. The liquid tank 3 stores ink, which is a liquid to be ejected onto a printing medium (not shown).

[0021] Figure 2 It is shown Figure 11 is a perspective view of the internal configuration of the liquid ejection device 1 shown. The liquid ejection device 1 includes a conveying roller 4 for conveying a printing medium (not shown), a liquid ejection head 5 ejecting a 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 arranged between the liquid tank 3 and the liquid ejection head 5. There is no particular limitation on the type of the printing medium as long as an image is formed on the printing medium by the liquid ejected from the liquid ejection head 5. The type of the printing medium may be, for example, paper, cloth, a disc label surface, a plastic sheet, an OHP sheet, or the like.

[0022] 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. As the liquid of the present embodiment, for example, four colors of ink (for example, cyan, magenta, yellow, and black) are used. In addition, four liquid tanks 3a to 3d storing inks of corresponding colors, respectively, are provided to the liquid tank 3. Hereinafter, in the case of identifying and referring to each liquid tank, letters are provided at the end, such as liquid tanks 3a to 3d, and in the case of referring to any liquid tank, it is referred to as the liquid tank 3. Each of the four liquid tanks 3a to 3d is arranged in the front surface portion of the liquid ejection device 1 inside the housing 2.

[0023] (Liquid tank)

[0024] Figure 3 yes Figure 1 1 is an exploded perspective view of a liquid tank 3 of a liquid ejecting apparatus 1 shown in FIG. The liquid tank 3 of the present embodiment includes a tank body 31 for storing liquid, an inlet 32 ​​communicating with a liquid storage chamber in the liquid tank body 31, and a tank cover 33 that can be mounted on the liquid tank body 31 so as to cover the inlet 32. The liquid tank 3 includes a communication passage 34 extending from the inlet 32 ​​to the interior of the liquid tank body 31 in a vertical direction. The communication passage 34 includes a liquid inlet path 34a (see FIG. 1 ) for allowing liquid to flow from a liquid storage container 10 described later into the liquid tank 3. Figure 4A ) and an air outlet path 34b for allowing the air in the liquid tank 3 to flow out (see Figure 4A ). The liquid inlet path 34a is arranged in parallel with the air outlet path 34b in the liquid tank 3, and extends longer than the air outlet path 34b in the vertical direction. The end of the liquid inlet path 34a is arranged at a position close to the bottom portion of the liquid tank 3. After the liquid tank 3 is refilled with liquid, in order to suppress evaporation of the liquid from the liquid storage chamber in the liquid tank body 31, the tank cover 33 is attached to the liquid tank body 31 to seal the liquid storage chamber in the liquid tank body 31.

[0025] (Refilling the fluid by gas-liquid exchange)

[0026] FIG. 4A to FIG. 4C It is an explanatory diagram of a state in which liquid is dispensed from the liquid storage container 10 into the liquid tank 3 according to the present embodiment.

[0027] In the present embodiment, the liquid tank 3 is refilled with liquid by gas-liquid exchange through the liquid storage container 10 from the inlet 32 ​​exposed by removing the tank cover 33 from the liquid tank body 31. Specifically, as Figure 4A As shown, the liquid tank 3 is in an empty state, and the liquid storage container 10 is in a state where liquid is stored therein. Then, by connecting the inlet and outlet ports of the liquid storage container 10 to the inlet 32 ​​of the liquid tank 3, the liquid tank 3 is started to be refilled with liquid. Once the refilling is started, as shown in FIG. Figure 4B As shown, the liquid in the liquid storage container 10 flows into the liquid tank 3 via the liquid inlet path 34a, while the air in the liquid tank 3 flows out into the liquid storage container 10 via the air outlet path 34b, and the liquid tank 3 continues to be refilled with liquid. Figure 4C As shown, once the liquid refilled in the liquid tank 3 reaches the end of the air outlet path 34b, the end of the air outlet path 34b in the liquid tank 3 is closed, and at the same time, the flow of liquid from the liquid storage container 10 to the liquid tank 3 is stopped.

[0028] Therefore, the liquid tank 3 can be refilled with liquid by gas-liquid exchange. In the present embodiment, the liquid tank is refilled with liquid by using a gas-liquid exchange system; however, it is not limited thereto, and other systems may be used.

[0029] (Liquid Storage Container)

[0030] Figure 5A is a side view of the liquid storage container 10 according to the present embodiment, and Figure 5B1 is a top view of a liquid storage container 10. In the present embodiment, the liquid storage container 10 shows a configuration including two liquid storage parts. The liquid storage container 10 includes a plurality of liquid storage parts 11 and 12, an outlet part 20, and a sealing part 21 that seals the outlet part 20. A partition wall 22 is formed in the liquid storage container 10, which is used to form the liquid storage parts 11 and 12 by dividing the liquid storage container 10 into two parts. Therefore, the liquid in the liquid storage container 10 can be prevented from mixing. The outlet part 20 is positioned in the top part of the liquid storage container 10 and is formed in a circular shape. The outlet part 20 includes outlets 15 and 16, through which liquids are dispensed from the plurality of liquid storage parts 11 and 12, respectively. The outlets 15 and 16 are arranged at the approximate center of the liquid storage container 10. The outlets 15 and 16 of the present embodiment are arranged at the approximate center of the liquid storage container 10; however, it is not limited thereto, and the outlets 15 and 16 may be arranged in the end parts. The first surface 19 including the connection surface connected to the outlets 15 and 16 of the liquid storage parts 11 and 12 is formed on the top portion of the liquid storage container 10, that is, on the top portions of the two liquid storage parts 11 and 12. On the first surface 19, it is preferred that A / B>1 is satisfied, where A is the arrangement spacing between the midpoints of the points where the center line CC passing through the centers of the adjacent outlets 15 and 16 intersects the areas of the liquid storage parts 11 and 12, and B is the arrangement spacing between the adjacent outlets 15 and 16.

[0031] Therefore, in the liquid storage container 10 according to the present embodiment, the outlets communicating with the plurality of liquid storage parts 11 and 12 can be synthesized into one shape and reduced in size, and thus the sealing part sealing the outlet can be reduced in size. Therefore, the number of components used for the liquid storage container can be reduced.

[0032] As a material forming the liquid storage container 10 , for example, PE (polyethylene), PP (polypropylene) or the like may be used, or other materials may be used. In addition, a recycled plastic material may be used as a material forming the liquid storage container 10 .

[0033] Note that, although the sealing portion 21 is formed in a cap shape in the present embodiment, it is not limited thereto, and the sealing portion 21 may be formed in a film shape. In the case of a film shape, the number of components for the liquid storage container 10 can be further reduced. In addition, by making the arrangement pitch B between the outlets 15 and 16 of the present embodiment and the arrangement pitch between the plurality of inlets 32 of the liquid tank 3 equal to each other, the two liquid tanks can be refilled with liquid at the same time.

[0034] <Variant 1>

[0035] Modification 1 of the first embodiment of the present disclosure is described. Descriptions of the basic configuration of the present disclosure and functions and configurations similar to those of the first embodiment are omitted, and different points are described.

[0036] The liquid ejection device generally performs full-color printing, and, for example, liquid tanks storing cyan, magenta, and yellow liquids may be arranged linearly. In this case, Figure 5A and Figure 5B The liquid storage container 10 in can store only two inks, and there is a possibility that refilling with three inks simultaneously cannot be performed. Therefore, in modification 1, a liquid storage container in which three liquid storage portions are formed so as to be refilled with three inks simultaneously is described.

[0037] Fig. 6A is a side view of a liquid storage container 10a according to the present embodiment, and Figure 6B 1 is a top view of a liquid storage container 10a. In variant 1, the liquid storage container 10a shows a configuration including three liquid storage parts. The liquid storage container 10a includes three liquid storage parts 11a, 12a and 13a and a sealing part 21a of a sealing outlet part 20a. Partition walls 22a and 23a are formed in the liquid storage container 10a, and these partition walls are used to form liquid storage parts 11a, 12a and 13a by dividing the liquid storage container 10a into three parts. The outlet part 20a is positioned in the top part of the liquid storage container 10a and is formed into a rectangular shape above the liquid storage parts 11a, 12a and 13a. The outlet part 20a includes outlets 15a, 16a and 17a, and liquids are dispensed from the three liquid storage parts 11a, 12a and 13a respectively through these outlets. The outlets 15a, 16a and 17a are linearly arranged at the approximate center of the liquid storage container 10a. The first surface 19a including the connection surface connected to the outlets 15a, 16a and 17a of the liquid storage parts 11a, 12a and 13a is formed on the top portion of the liquid storage container 10a, that is, on the top portions of the three liquid storage parts 11a, 12a and 13a. On the first surface 19a, it is preferred that A / B>1 is satisfied, where A is the arrangement spacing between the midpoints of the points where the center lines CC of the three adjacent outlets 15a, 16a and 17a intersect with the areas of the liquid storage parts 11a and 12a, and B is the arrangement spacing between the adjacent outlets 15a and 16a. At the same time, on the first surface 19a, it is preferred that A / B>1 is satisfied, where A is the arrangement spacing between the midpoints of the points where the center lines CC of the three adjacent outlets 15a, 16a and 17a intersect with the areas of the liquid storage parts 12a and 13a, and B is the arrangement spacing between the adjacent outlets 16a and 17a.

[0038] Therefore, in the liquid storage container 10 according to the present embodiment, the outlets communicating with the plurality of liquid storage parts 11a, 12a and 13a can be synthesized into one shape and reduced in size, and thus the sealing part sealing the outlet can be reduced in size. Therefore, the number of components used for the liquid storage container can be reduced.

[0039] <Variant 2>

[0040] Modification 2 of the first embodiment of the present disclosure is described. Descriptions of the basic configuration of the present disclosure and functions and configurations similar to those of the first embodiment are omitted, and different points are described.

[0041] In the liquid storage container of modification 1, the liquid storage parts 11a, 12a and 13a are arranged linearly. Incidentally, there is also a case where the liquid tank is not arranged linearly but arranged in a circular form. Therefore, in modification 2, a liquid storage container is described in which three liquid storage parts are formed in a circular form to correspond to the arrangement of the liquid tank.

[0042] Fig. 7A is a side view of a liquid storage container 10b according to the present embodiment, and Figure 7BIt is a top view of the liquid storage container 10b. In variation 2, the liquid storage container 10b shows a configuration including three liquid storage parts in a circular form. The liquid storage container 10b includes three liquid storage parts 11b, 12b and 13b and a sealing part 21b of the sealing outlet part 20a. Partition walls 22b, 23b and 24b are formed in the liquid storage container 10b, and these partition walls are used to form liquid storage parts 11b, 12b and 13b by dividing the liquid storage container 10b into three parts in a fan-shaped form. The outlet part 20b is positioned in the top part of the liquid storage container 10b and is formed into a circular shape above the liquid storage parts 11b, 12b and 13b. The outlet part 20b includes outlets 15b, 16b and 17b, and liquids are respectively distributed from the three liquid storage parts 11b, 12b and 13b through these outlets. The outlets 15b, 16b and 17b are arranged in the approximate center of the liquid storage container 10b in a circular form. A first surface 19b including connection surfaces connected to the outlets 15b, 16b and 17b of the liquid storage parts 11b, 12b and 13b is formed on the top portion of the liquid storage container 10b, that is, on the top portions of the three liquid storage parts 11b, 12b and 13b. On the first surface 19b, it is preferred that A / B>1 is satisfied, wherein A is the arrangement spacing between the midpoints of the points where the center lines CC of any two of the three adjacent outlets 15b, 16b and 17b intersect with the areas of the liquid storage parts of the two outlets, and B is the arrangement spacing between two adjacent outlets. Specifically, it is preferred that A / B>1 is satisfied, wherein A is the arrangement spacing between the midpoints of the points where the center lines CC of the two adjacent outlets 15b and 16b intersect with the areas of the liquid storage parts 11b and 12b, and B is the arrangement spacing between the adjacent outlets 15b and 16b. Likewise, it is preferred that A / B>1 is satisfied, where A is the arrangement spacing between the midpoints of the points where the center lines (not shown) of two adjacent outlets 16b and 17b intersect the areas of the liquid storage parts 12b and 13b, and B is the arrangement spacing between adjacent outlets 16b and 17b. In addition, it is also preferred that A / B>1 is satisfied, where A is the arrangement spacing between the midpoints of the points where the center lines (not shown) of two adjacent outlets 15b and 17b intersect the areas of the liquid storage parts 11b and 13b, and B is the arrangement spacing between adjacent outlets 15b and 17b.

[0043] Therefore, in the liquid storage container 10b according to the present embodiment, the outlets communicating with the plurality of liquid storage parts 11b, 12b and 13b can be synthesized into one shape and reduced in size, and thus the sealing part sealing the outlet can be reduced in size. Therefore, the number of components used for the liquid storage container can be reduced.

[0044] <Variant 3>

[0045] Modification 3 of the first embodiment of the present disclosure is described. Descriptions of the basic configuration of the present disclosure and functions and configurations similar to those of the first embodiment are omitted, and different points are described.

[0046] In the liquid storage container of modification 1, the liquid storage parts 11a, 12a and 13a are arranged linearly. By the way, there is also a case where the liquid tank is not arranged linearly but arranged in a rectangular form. Therefore, in modification 3, a liquid storage container is described in which three liquid storage parts are formed in a rectangular form to correspond to the arrangement of the liquid tank.

[0047] Fig. 8A is a side view of a liquid storage container 10c according to the present embodiment, and Figure 8B It is a top view of the liquid storage container 10c. In variant 3, the liquid storage container 10c shows a configuration including three liquid storage parts in a rectangular form. The liquid storage container 10c includes three liquid storage parts 11c, 12c and 13c and a sealing part 21c of the sealing outlet part 20c. Partition walls 22c, 23c and 24c are formed in the liquid storage container 10c, and these partition walls are used to form liquid storage parts 11c, 12c and 13c by dividing the liquid storage container 10c into three parts in a rectangular form. The liquid storage part 11c is formed to divide the liquid storage container 10c into two parts by the partition wall 22c and the partition wall 24c. In addition, the liquid storage part 12c and the liquid storage part 13c are formed so that a part of the divided liquid storage container 10c is divided into two parts by the partition wall 23c. The outlet part 20c is positioned in the top part of the liquid storage container 10b and is formed into a circular shape above the liquid storage parts 11c, 12c and 13c. The outlet portion 20c includes outlets 15c, 16c and 17c, through which liquid is dispensed from the three liquid storage portions 11c, 12c and 13c, respectively. The outlets 15c, 16c and 17c are arranged at the approximate center of the liquid storage container 10c. A first surface 19c including connection surfaces connected to the outlets 15c, 16c and 17c of the liquid storage portions 11c, 12c and 13c is formed on the top portion of the liquid storage container 10c, that is, on the top portions of the three liquid storage portions 11c, 12c and 13c. On the first surface 19c, preferably, A / B>1 is satisfied, where A is the arrangement spacing between the midpoints of the points where the center lines CC of two adjacent outlets 15c and 16c intersect with the regions of the liquid storage portions 11c and 12c, and B is the arrangement spacing between adjacent outlets 15c and 16c.

[0048] Therefore, in the case where a large amount of consumed liquid is stored in the liquid storage portion having a large capacity, refilling of the liquid including the large amount of consumed liquid can be performed at once.

[0049] <Variant 4>

[0050] Modification 4 of the first embodiment of the present disclosure is described. Descriptions of the basic configuration of the present disclosure and functions and configurations similar to those of the first embodiment are omitted, and different points are described.

[0051] In a liquid ejecting apparatus that performs general full-color printing, for example, liquid tanks storing cyan, magenta, yellow, and black liquids may be arranged close to each other. In variation 4, a liquid storage container is described in which four liquid storage portions are formed to refill the liquid tanks with four inks.

[0052] Fig. 9A is a side view of a liquid storage container 10d according to the present embodiment, and Fig. 9B4 is a top view of a liquid storage container 10d. In variation 4, the liquid storage container 10d shows a configuration including four liquid storage parts in a rectangular form. The liquid storage container 10d includes four liquid storage parts 11d, 12d, 13d and 14d and a sealing part 21d that seals the outlet part 20d. Partition walls 22d, 23d, 24d and 25d are formed in the liquid storage container 10d, and these partition walls are used to form liquid storage parts 11d, 12d, 13d and 14d by dividing the liquid storage container 10d into four parts in a rectangular form. The liquid storage part 11d is formed by a partition wall 22d and a partition wall 25d. In addition, the liquid storage part 12d is formed by a partition wall 22d and a partition wall 23d. In addition, the liquid storage part 13d is formed by a partition wall 23d and a partition wall 24d. In addition, the liquid storage part 14d is formed by a partition wall 24d and a partition wall 25d. The outlet portion 20d is positioned in the top portion of the liquid storage container 10d and is formed in a circular shape above the liquid storage portions 11d, 12d, 13d and 14d. The outlet portion 20d includes outlets 15d, 16d, 17d and 18d, through which liquid is dispensed from the four liquid storage portions 11d, 12d, 13d and 14d, respectively. The outlets 15d, 16d, 17d and 18d are arranged at the approximate center of the liquid storage container 10d. A first surface 19d including connection surfaces connected to the outlets 15d, 16d, 17d and 18d of the liquid storage portions 11d, 12d, 13d and 14d is formed on the top portion of the liquid storage container 10d, that is, on the top portions of the four liquid storage portions 11d, 12d, 13d and 14d. On the first surface 19d, preferably, A / B > 1 is satisfied, where A is the arrangement spacing between the midpoints of the points where the center lines CC of two adjacent outlets 15d and 16d intersect the areas of the liquid storage portions 11d and 12d, and B is the arrangement spacing between adjacent outlets 15d and 16d.

[0053] In the case of the liquid storage container according to the present disclosure, multiple liquids can be dispensed at one time through multiple liquid storage parts and outlets connected to the multiple liquid storage parts. Therefore, the convenience of the user to refill the ink can be improved. In this case, due to the above-mentioned gas-liquid exchange, even in the case of one-time dispensing, once the liquid storage part is full, refilling can be automatically stopped. Therefore, the required amount of liquid can be dispensed without worrying about liquid overflow.

[0054] As described above, the liquid storage container according to the present disclosure includes a plurality of liquid storage parts for storing liquid and a plurality of liquid outlets, and the liquid is dispensed from the plurality of liquid storage parts through the plurality of liquid outlets, respectively. On the first surface of the plurality of liquid storage parts including the connection surface connected to the liquid outlet of the liquid storage part, the arrangement spacing between the midpoints of the points where the center line through the center of the adjacent liquid outlets intersects with the area of ​​the liquid storage part is A, and the arrangement spacing between the adjacent liquid outlets is B. The relationship between the arrangement spacing A and the arrangement spacing B satisfies A / B>1. Therefore, a liquid storage container can be provided, which can reduce the number of components used for the liquid storage container by sharing and reducing the size of the constituent components of the liquid storage container.

[0055] <Second Embodiment>

[0056] A second embodiment according to the present disclosure is described. Note that descriptions of portions overlapping with the first embodiment are omitted.

[0057] A first surface 19 including a connection surface connected to the liquid outlet of the liquid storage portion is formed on the liquid storage container 10 according to the second embodiment. In the liquid storage container 10, on the first surface 19, the arrangement spacing between 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 area of ​​the liquid storage portion is A, and the arrangement spacing between the adjacent liquid outlets is B. In this case, A / B>1, and there is also A / B<2. It is preferred that the ratio between the arrangement spacing A and the arrangement spacing B is A / B<2, because this is a range to prevent the liquid storage portion from being too large in size. In addition, since this is a range to prevent the outlets from being too close to each other, this is preferred because the ink mixing between the adjacent outlets can be suppressed. It should be noted that since the liquid storage container 10 is molded similarly to the liquid storage container in Example 1, liquid overflow when dispensing liquid can be suppressed like Example 1.

[0058] It is preferred that there is a partition wall between the outlets because mixing of liquids between the outlets can be suppressed. In addition, it is more preferred that the height of the partition wall is higher than the height of each outlet.

[0059] like FIG. 10A to FIG. 10EAs shown, the member 29 that defines how the outlets are arranged can be arranged in each of the combined outlet portions 20, 20a, 20b, 20c and 20d. By attaching the liquid storage container 10 in the direction along which the member 29 that defines how the outlets are arranged is assembled to the member (not shown) that defines how the liquid tank 3 is arranged, it is possible to suppress the refilling of the liquid tank with the wrong liquid when the liquid is refilled. It should be noted that although the shape of the member 29 that defines how the outlets are arranged is shown as a rectangle as an example in the second embodiment, other shapes can also be applied. According to this embodiment, in a liquid storage container including a plurality of liquid storage portions, since the minimum number of members 29 that define how the outlets are arranged is one, the number of members used for the liquid storage container can be reduced.

[0060] As described above, according to the present disclosure, liquid overflow during liquid refilling can be suppressed in a liquid storage container that allows a printer to be refilled with multiple liquids at one time. In addition, refilling a liquid tank with an incorrect liquid during liquid refilling can be suppressed. In addition, a liquid storage container can be provided that can reduce the number of components used for a liquid storage container by sharing and reducing the size of the constituent components of the liquid storage container. In other words, the number of discarded components can be reduced. Since the components of the liquid storage container contain plastic, the reduction in discarded components, in other words, the amount of discarded plastic can be reduced. Therefore, the technology described in this specification has the potential to contribute to the realization of a sustainable society (such as a decarbonized society / circular society).

[0061] While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.The scope of the following claims is to be accorded the broadest interpretation so as to encompass all such modifications and equivalent structures and functions.
