Description

[[Technical Field]]

[0001] The present invention relates to a container suitable for storing liquid and a method for manufacturing the container. [[Background Art]]

[0002] For example, in an inkjet image recording apparatus, an ink containing cartridge for replenishing ink is replaceable. Some cartridges include a bag that stores ink and a case that houses the bag.

[0003] Patent Document 1 discloses a configuration in which a liquid storage bag provided with a spout is housed in a case having a spout support portion. The case is composed of a first case and a second case, and the internal space of the case is opened or closed by sliding the two cases relative to each other.

[0004] [[Patent Document 1]] Japanese Unexamined Patent Publication No. 2017-065152 [[Summary of the Invention]] [[Problem to be Solved by the Invention]]

[0005] In a relatively small cartridge as disclosed in Patent Document 1, it is easy to place a liquid storage bag filled with ink in the case. However, as the liquid storage capacity increases, the bag also becomes larger, and when filled with liquid, it also becomes heavier. In addition, the bag expands greatly due to liquid filling. If the bag is bent inside the case, the liquid filled in the bag is blocked at the bent portion, which may hinder the filling of liquid into the bag.

[0006] The present invention has been made in view of the foregoing circumstances, and an object of the present invention is to provide a means that facilitates assembly by housing a pouch in a case. [Means for solving the problem]

[0007] (1) The container according to the present invention comprises a box-shaped case having an opening; a cover rotatably connected to the case and movable between a first position that closes a portion of the opening of the case and a second position that opens the opening of the case; a pouch having a flexible bag and a spout; a locking position that holds the cover in the first position relative to the case and a locking part that moves to an unlocking position that allows the cover to rotate from the first position. The case has a bottom wall and side walls that rise from the bottom wall. The opening exposes the internal space through at least a portion of the side wall. The side wall that defines the opening has a locking part that locks the spout. The rotating tip of the cover defines the opening. The locking part is located on the side wall that defines the opening or on the rotating tip.

[0008] The operation of moving the cover from the first position to the second position, housing the pouch in the internal space of the case and locking the spout to the locking part, and then moving the cover from the second position to the first position and moving the locking part from the unlocked position to the locked position can be performed from the side wall that partitions the opening.

[0009] (2) The opening also opens the internal space of the case upward, and the cover in the first position may close the top of the opening.

[0010] When the cover is in the second position, the pouch can be easily placed into the internal space of the case through the opening.

[0011] (3) The bag is capable of containing liquid, and the spout has an outlet for the liquid contained in the bag to flow out to the outside, and a flange located around the outlet, and the locking part may lock the flange.

[0012] (4) The container may have screws and screw holes connecting the case and the cover in the first position.

[0013] (5) The method for manufacturing a container according to the present invention involves placing a flexible bag and a pouch having a spout in the internal space of a box-shaped case having a bottom wall and side walls rising from the bottom wall, locking the spout on the periphery of an opening that exposes the internal space of the case through at least a part of the side wall, and filling the bag with liquid through the spout while the opening of the case is covered.

[0014] Since the liquid can be filled into a pouch housed in a case with its opening sealed by a cover, it offers better operability compared to the method of loading a liquid-filled pouch into the case. [Effects of the Invention]

[0015] According to the present invention, it is easy to house the pouch in the case and assemble it. [Brief explanation of the drawing]

[0017] Preferred embodiments of the present invention are described below. It should be noted that the present embodiment is merely one embodiment of the present invention, and it goes without saying that the embodiment can be modified within a scope that does not change the gist of the present invention. Also, in the following description, progression from the starting point to the ending point of an arrow is expressed as "direction", and movement back and forth along the line connecting the starting point and ending point of the arrow is expressed as "orientation". In addition, in the following description, the up-down direction 7 is defined with reference to the state where the image recording apparatus 100 is installed and ready for use (the state shown in FIG. 1), the front-back direction 8 is defined with the side on which the discharge port 33 is provided as the front side, and the left-right direction 9 is defined when the image recording apparatus 100 is viewed from the front side.

[0018] [External Configuration of Image Recording Apparatus 100] The image recording apparatus 100 shown in FIG. 1 records an image on a sheet S forming a roll 37 (see FIG. 2) by an inkjet recording method.

[0019] As shown in FIG. 1, the image recording apparatus 100 includes a housing 30. The housing 30 includes an upper housing 31 and a lower housing 32. The upper housing 31 and the lower housing 32 have a generally rectangular parallelepiped shape as a whole, and are sized to be placed on a desk. That is, the image recording apparatus 100 is suitable for being placed on a desk for use. Of course, the image recording apparatus 100 may also be placed on a floor or a rack for use. Note that a frame for supporting each member may be appropriately provided inside the housing 30.

[0020] As shown in FIG. 2, the upper housing 31 is rotatably supported by the lower housing 32. The upper housing 31 is rotatable around a rotating shaft 15 provided at the rear lower end and extending in the left-right direction 9, between a closed position shown in FIG. 2 and an open position. Note that the configuration for rotating the upper housing 31 is not limited to the one using the rotating shaft 15, and may be rotated by, for example, a hinge.

[0021] As shown in Figure 2, when the upper housing 31 is in the closed position, the internal space 31A of the upper housing 31 and the internal space 32A of the lower housing 32 are shielded from the outside. When the upper housing 31 is in the open position, the internal space 31A of the upper housing 31 and the internal space 32A of the lower housing 32 are exposed to the outside.

[0022] As shown in Figure 1, a long, slit-shaped discharge port 33 is formed on the front surface 32F of the lower housing 32, extending in the left-right direction 9. The image-recorded sheet S (see Figure 2) is discharged from the discharge port 33.

[0023] An operation panel 44 is provided on the front 31F of the upper housing 31. The user makes inputs on the operation panel 44 to operate the image recording device 100 and confirm various settings.

[0024] As shown in Figure 1, the right cover 35A is located on the right side 32R of the lower housing 32. Opening and closing the right cover 35A exposes or conceals the holder 35, etc. (see Figure 2) located in the seat storage space 32C.

[0025] As shown in Figure 1, a front cover 39 is located on the front surface 32F of the lower housing 32. The front cover 39 can be opened so that its upper end tilts forward around a pivot axis (not shown) that extends along the left-right direction 9 near its lower end. Opening and closing the front cover 39 exposes or conceals the mounting case 110, etc. (see Figure 2) located in the internal space 32A of the lower housing 32.

[0026] [Internal configuration of the image recording device 100] As shown in Figure 2, the internal spaces 31A and 32A contain the holder 35, tensioner 45, transport roller pair 36, transport roller pair 40, head unit 38, platen 51, ink tank 34, and mounting case 110, among others. Although not shown, the internal space 32A may contain the fuser unit, image sensor, cutter, maintenance mechanism, etc.

[0027] A partition wall 41 is provided in the internal space 32A. The partition wall 41 separates the rear lower part of the internal space 32A, thereby partitioning the seat storage space 32C. The seat storage space 32C is surrounded by the partition wall 41 and the lower housing 32, and is isolated from the head unit 38 and other components.

[0028] The sheet storage space 32C accommodates a roll body 37. The roll body 37 has a core tube and a long sheet S. The sheet S is wound around the core tube in a roll shape in the circumferential direction of the core tube's axis. The sheet S can have a width ranging from the minimum width to the maximum width at which the image recording device 100 can record images. In other words, the sheet storage space 32C can accommodate multiple types of roll bodies 37 with different widths. Alternatively, the roll body 37 may not have a core tube, and the sheet S may be wound in a roll shape so that it can be attached to the holder 35. Furthermore, the sheet storage space 32C may also accommodate fanfold paper.

[0029] As shown in Figure 2, the sheet storage space 32C opens upward at the rear. More specifically, a gap 42 is formed between the partition wall 41 and the rear surface 32B, i.e., above the rear end of the roll body 37. The sheet S is pulled upward from the rear end of the roll body 37 by the rotation of the conveyor roller pair 36, 40 and guided through the gap 42 to the tensioner 45.

[0030] The tensioner 45 is located above the partition wall 41 at the rear of the internal space 32A. The tensioner 45 has an outer peripheral surface 45A facing outwards from the lower housing 32. The outer peripheral surface 45A is larger than the maximum width of the sheet in the left-right direction 9 and has a shape that is symmetrical with respect to the paper feeding center (the center of the sheet S in the left-right direction 9). The upper end of the outer peripheral surface 45A is at approximately the same vertical position as the nip D of the conveying roller pair 36 in the vertical direction 7.

[0031] The sheet S, pulled out from the roll body 37, is placed on and in contact with the outer circumferential surface 45A. The sheet S curves forward along the outer circumferential surface 45A and extends in the conveying direction 8A, and is guided by the conveying roller pair 36. The conveying direction 8A is forward along the front-rear direction 8. The tensioner 45 applies tension to the sheet S by a well-known method.

[0032] A pair of conveyor rollers 36 is located in front of the tensioner 45. The pair of conveyor rollers 36 has a conveyor roller 36A and a pinch roller 36B. The conveyor roller 36A and the pinch roller 36B are in contact with the upper end of the outer circumferential surface 45A at approximately the same vertical position.

[0033] A pair of conveyor rollers 40 is located in front of the conveyor roller pair 36. The conveyor roller pair 40 has a conveyor roller 40A and a pinch roller 40B. The conveyor roller 40A and the pinch roller 40B are in contact with the upper end of the outer circumferential surface 45A at approximately the same vertical position.

[0034] The conveyor rollers 36A and 40A are driven by a motor (not shown) and rotate. The conveyor roller pair 36 rotates while nipping the sheet S extending from the tensioner 45 in the conveying direction 8A, thereby feeding it along the conveying surface 43A in the conveying direction 8A. The conveyor roller pair 40 rotates while nipping the sheet S fed out by the conveyor roller pair 36, thereby feeding it along the conveying direction 8A. In addition, the rotation of the conveyor roller pairs 36 and 40 causes the sheet S to be pulled out from the sheet storage space 32C through the gap 42 towards the tensioner 45.

[0035] As shown in Figure 2, a transport path 43 is formed in the internal space 32A, extending from the upper end of the outer peripheral surface 45A to the discharge port 33. The transport path 43 extends almost linearly along the transport direction 8A and is a space through which the sheet S can pass. In detail, the transport path 43 extends in the transport direction 8A and the left-right direction 9 and follows a transport surface 43A that is longer in the transport direction 8A. In Figure 2, the transport surface 43A is shown by a dashed line indicating the transport path 43. The transport path 43 is partitioned by guide members (not shown) located at a distance in the vertical direction 7, as well as a head unit 38, a platen 51, and the like.

[0036] The head unit 38 is located above the transport path 43, downstream of the transport roller pair 36 in the transport direction 8A. The head unit 38 has a head module 49 having a plurality of nozzles 38A. Ink is ejected downward from the plurality of nozzles 38A toward the sheet S supported by the transport belt 101. This records an image on the sheet S.

[0037] The platen 51 is located below the conveyor path 43, downstream of the conveyor roller pair 36 in the conveying direction 8A. The platen 51 is located below the head unit 38 and faces the head unit 38. The platen 51 has a conveyor belt 101 and a support section 104. The conveyor belt 101 supports the sheet S, which is conveyed in the conveying direction 8A by the conveyor roller pair 36 and located directly below the head unit 38. The conveyor belt 101 conveys the supported sheet S in the conveying direction 8A.

[0038] The mounting case 110 is located near the front and lower ends of the lower housing 32 and is a box shape that opens forward. The ink tank 34 is inserted into the mounting case 110 facing backward. An ink needle 112 extending forward is located on the rearward end surface 111 of the mounting case 110. The front end of the ink needle 112 is open, and the rear end is connected to an ink tube 113. The ink tube 113 connects the internal space of the ink needle 112 to the head unit 38 so that ink can flow through it. When the ink tank 34 is mounted in the mounting case 110, the ink needle 112 is inserted into the outlet 90 (see Figure 3) of the ink tank 34. As a result, the ink stored in the ink tank 34 is supplied to the head unit 38 through the ink needle 112 and the ink tube 113.

[0039] [Ink Tank 34] The ink tank 34 (an example of a container) stores ink. Ink is a liquid containing pigments and other materials. The ink has a viscosity suitable for uniformly dispersing the pigments. The pigments are what give the ink its color. When the ink in the ink tank 34 is consumed, it is removed from the mounting case 110 and replaced with a new ink tank 34 that contains ink.

[0040] As shown in Figures 3 to 5, the ink tank 34 has a case 60, a cover 61, and a pouch 80. In the following description, the vertical direction 7, the front-to-back direction 8, and the left-to-right direction 9 of the ink tank 34 are described in accordance with the directions of the housing 30 when the ink tank 34 is mounted in the mounting case 110.

[0041] The case 60 is box-shaped with upward and rearward openings 62. The case 60 has a bottom wall 63, a front wall 64, a rear wall 65 (an example of a side wall), a left wall 66, and a right wall 67. The bottom wall 63 is a rectangle that is long in the front-to-back direction 8 when viewed from the vertical direction 7. The front wall 64 extends upward from the front end of the bottom wall 63. A recess 64A that recedes backward is formed at the lower end of the front wall 64. The recess 64A serves as a handle when the user pulls out the case 60. The rear wall 65 extends upward from the rear end of the bottom wall 63. The upper end of the rear wall 65 is located below the upper end of the front wall 64.

[0042] The left wall 66 extends upward from the left end of the lower wall 63 and connects the front wall 64 and the rear wall 65. A portion of the upper end of the left wall 66 slopes downward toward the rear. The right wall 67 extends upward from the right end of the lower wall 63 and connects the front wall 64 and the rear wall 65. A portion of the upper end of the right wall 67 slopes downward toward the rear.

[0043] As shown in Figure 5, the opening 62 is demarcated by the upper end of the front wall 64, the upper end of the rear wall 65, the upper end of the left wall 66, and the upper end of the right wall 67. The opening 62 exposes the internal space of the case 60 to the outside. A notch 68 (an example of a locking portion) is formed in a part of the upper end of the rear wall 65, extending downward through the opening 62 so that the flange 91 of the spout 82 can engage with it.

[0044] A cover 61 is rotatably connected to the upper end of the front wall 64 of the case 60 via a pivot shaft 69. The pivot shaft 69 protrudes outward along the left-right direction 9 at both the upper and left-right ends of the front wall 64. The cover 61 is rotatable about the left-right direction 9 as its axis. The cover 61 is rotatable between a first position (shown in Figure 3) that closes a portion (upper part) of the opening 62 of the case 60 and a second position (shown in Figure 5) that opens the opening 62.

[0045] The cover 61 has an upper wall 70, a front wall 71, a rear wall 72 (an example of a pivoting tip), a left wall 73, and a right wall 74. The upper wall 70, front wall 71, rear wall 72, left wall 73, and right wall 74 are described based on the state in which the cover 61 is in a first position. The upper wall 70 is a rectangle that is long in the front-to-back direction when viewed from the vertical direction 7 and has the same planar shape as the lower wall 63 of the case 60. The front wall 71 extends downward from the front end of the upper wall 70. The lower end of the front wall 71 is connected to the front wall 64 of the case 60 via a pivot shaft 69. The rear wall 72 extends downward from the rear end of the upper wall 70. The lower end of the rear wall 72 is located below the lower end of the front wall 64. A notch 75 extending upward is formed in a part of the lower end of the rear wall 72. The notch 75 forms a continuous space with the notch 68 of the case 60 when the cover 61 is in the first position. In other words, the notch 75 of the rear wall 72 partitions a portion of the opening 62 when the cover 61 is in the first position.

[0046] The left wall 73 extends downward from the left end of the upper wall 70 and connects the front wall 71 and the rear wall 72. A portion of the lower end of the left wall 73 slopes downward toward the rear. The right wall 74 extends downward from the right end of the upper wall 70 and connects the front wall 71 and the rear wall 72. A portion of the lower end of the right wall 74 slopes downward toward the rear.

[0047] A lock lever 76 is located on the rear wall 65 of the case 60. The lock lever 76 is rotatably connected to the rear wall 65 with its axis in the left-right direction 9, and is rotatable between a locked position extending along the outer surface of the rear wall 65 and an unlocked position standing upright relative to the outer surface of the rear wall 65. A through hole 76A is formed at the rotating tip of the lock lever 76.

[0048] A claw portion 77 is located near the lower end of the rear wall 72 of the cover 61, protruding toward the rear. When the cover 61 is in the first position, the claw portion 77 enters and engages with the through hole 76A of the lock lever 76 in the locked position. This holds the cover 61 in the first position. When the lock lever 76 is in the unlocked position, the claw portion 77 is disengaged from the through hole 76A of the lock lever 76. This allows the cover 61 in the first position to rotate toward the second position.

[0049] Screw fastening portions 78 and 79 are located near the upper end of the rear wall 65 of the case 60 and near the lower end of the rear wall 72 of the cover 61, respectively. When the cover 61 is in the first position, the screw fastening portions 78 and 79 face each other in the vertical direction 7. Holes (an example of screw holes) extending in the vertical direction 7 are formed in the screw fastening portions 78 and 79, and the cover 61 in the first position is fixed to the case 60 by inserting and screwing screws 59 through the screw fastening portions 78 and 79.

[0050] As shown in Figure 5, the internal space of the case 60 houses a pouch 80 for storing ink. As shown in Figure 6, the pouch 80 has a flexible bag 81 and a spout 82 (an example of a stopper).

[0051] As shown in Figures 6 and 9, the bag 81 expands into a cube shape by welding a sheet of synthetic resin. The bag 81 can be folded into the thin, flat sheet shape shown in Figure 9 by valley folding the parts that become the front wall 83 and rear wall 84 in the cubic shape inward in the front-to-back direction 8, and mountain folding the parts that become the left wall 87 and right wall 88 in the cubic shape outward in the left-to-right direction 9. The top wall 85 (see Figure 6) in the cubic shape is located on the top surface in the folded state. Although not shown in Figure 9, the bottom wall 86 (see Figure 6) in the cubic shape is located on the bottom surface in the folded state. As shown in Figure 9, the welded parts 89 extending in directions inclined with respect to the front-to-back direction 8 and left-to-right direction 9, respectively, are provided symmetrically with respect to the left-to-right direction 9 in the left wall 87 and right wall 88, so that liquid does not enter the bag 81 beyond the welded parts 89 in the left-to-right direction 9. As a result, the bag 81 expands into a cubic shape, forming the left wall 87 and the right wall 88.

[0052] As shown in Figure 6, the spout 82 is located near the lower end of the rear wall 84 of the bag 81. The spout 82 is made of synthetic resin. The spout 82 has a rearward-facing outlet 90. The outlet 90 is an outward-facing opening of a flow path that connects the internal space of the bag 81 to the outside. The flow path extends forward from the outlet 90 into the spout 82, and the spout 82 is connected to an opening formed in the rear wall 84 of the bag 81, thereby connecting the flow path to the internal space of the bag 81. Although not shown in detail, the outlet 90 may be openable and closable by a valve or the like.

[0053] In the spout 82, the area around the outlet 90 is a flange 91 that protrudes outward. The flange 91 has a shape that corresponds to the notch 68 in the rear wall 65 of the case 60. As shown in Figures 7 and 8, a pair of projections 92 and 93 are located at the left and right ends of the flange 91, respectively, which sandwich the periphery of the notch 68 in the front-rear direction 8. When the flange 91 is inserted downward from above the notch 68, the periphery of the notch 68 of the rear wall 65 enters between the pair of projections 92 and 93. This locks the flange 91 into the rear wall 65. Note that Figures 7 and 8 show the state just before the pair of projections 92 and 93 are inserted into the notch 68 of the rear wall 65 and the periphery of the notch 68 of the rear wall 65 enters between the pair of projections 92 and 93, and the bag 81 is omitted.

[0054] [Manufacturing method for ink tank 34] The manufacturing method of the ink tank 34 is described below. With the cover 61 in the second position relative to the case 60, the pouch 80, which does not contain ink in its bag 81, is housed in the internal space of the case 60. At this time, the bag 81 of the pouch 80 is folded flat, as shown in Figure 9. The left-right dimension 9 of the flat-folded bag 81 is larger than the left-right dimension 9 of the internal space of the case 60. Therefore, the left and right ends of the bag 81, i.e., the left wall 87 and the right wall 88, are curved upward, in other words, the bag 81 is curved into a U-shape and housed in the internal space of the case 60. Also, the spout 82 of the pouch 80 is positioned in the notch 75 by the flange 91 being locked to the rear wall 65, as shown in Figures 7 and 8. As the bag 81 is curved, when it expands into a cubic shape, it roughly fits the internal space of the case 60, and when folded, the pouch 80, which has a bag 81 larger than the internal space of the case 60, is housed in the internal space of the case 60.

[0055] Next, as shown in Figure 4, the cover 61 is rotated from the second position to the first position relative to the case 60, and the lock lever 76 is set to the locked position. Also, screws 59 are screwed into the holes of the screw fastening parts 78 and 79. This holds the cover 61 in the first position. After that, for example, the nozzle of an ink filling machine is inserted into the outlet 90 of the spout 82, and ink is filled into the internal space of the bag 81 through the nozzle. As the ink is filled, the folded bag 81 expands its folded gusset portion; in other words, the front wall 83 and rear wall 84, which are folded inward, stand up, and the left wall 87 and right wall 88, which are folded outward, stand up, resulting in the cubic shape shown in Figures 5 and 6.

[0056] [Effects of this embodiment] According to the embodiment described above, the operation of moving the cover 61 from the first position to the second position, housing the pouch 80 in the internal space of the case 60 and locking the spout 82 into the notch 68, and moving the cover 61 from the second position to the first position and moving the lock lever 76 from the unlocked position to the locked position can be performed from the rear wall 65 side of the case 60, making it easy to house the pouch 80 in the case 60 and assemble it.

[0057] Furthermore, when the cover 61 is in the second position, the pouch 80 can be easily housed in the internal space of the case 60 through the opening 62.

[0058] Furthermore, since the pouch 80, which is housed in a case 60 with a portion of the opening 62 covered by a cover 61, can be filled with ink, it offers better operability compared to the method of loading an ink-filled pouch 80 into the case 60.

[0059] [Differentiation] In the embodiment described above, the opening 62 of the case 60 faces upward and rearward, but the opening 62 may face only upward. Also, the shape of the cover 61 may be changed as appropriate in accordance with the change in the shape of the opening 62.

[0060] Furthermore, the lock lever 76 may be located on the left wall 66 or right wall 67 instead of the rear wall 65, or it may be located on the cover 61. Similarly, the screw fastening parts 78 and 79 may be located on the left wall 66 or right wall 67 instead of the rear wall 65, or they may be in a different position from the lock lever 76.

[0061] Furthermore, although ink is described as an example of a liquid in the embodiments described above, for example, instead of ink, a pre-treatment liquid that is discharged onto paper or the like before the ink during printing may be stored in the ink tank 34. Also, water for cleaning the head module 49 may be stored in the ink tank 34.
