Liquid storage containers and liquid injection devices

Abstract

The object of this invention is to provide a liquid storage container that reduces the possibility of liquid spillage when the cover member is removed. The cover member has a cover portion capable of covering an opening, and a handle portion protruding from the cover portion in a direction where the handle portion moves further away from the opening. When the cover member is attached to the opening, pushing the handle portion from the outside of the opening toward the inside allows the cover portion to deform into a convex shape, and when the handle portion is pulled upward from the inside of the opening toward the outside while the cover portion is already deformed into a convex shape, pulling the handle portion upward from the inside of the opening toward the outside allows the cover portion to deform from a convex shape to a concave shape. This invention also provides a liquid spraying device.

Description

Technical Field

[0001] This invention relates to liquid storage containers and liquid spraying devices. Background Technology

[0002] Japanese Patent Application Publication No. 2012-20497 discloses a liquid storage container including a plug member (also called a "cap member") that can be detachably attached, and a liquid injection device including the liquid storage container.

[0003] According to Japanese Patent Application Publication No. 2012-20497, the plug component is tightly fitted to the liquid inlet (also known as the "supply port") of the liquid storage container. Therefore, if the user pulls the plug component forcefully when disassembling it, the liquid adhering to the plug component may scatter in the surrounding area.

[0004] Therefore, the objective of the present invention is to provide a liquid storage container that can reduce the possibility of liquid spillage when the cover component is removed. Summary of the Invention

[0005] To achieve the above objectives, the liquid storage container according to the present invention includes: a container body having an opening; and a lid member detachably attached to the opening, wherein the lid member has: a cover portion capable of covering the opening; and a handle portion protruding from the cover portion in a direction in which the handle portion becomes further away from the opening, and the cover portion being deformable into a convex shape when the handle portion is pushed from the outside of the opening toward the inside while the lid member is attached to the opening, and the cover portion being deformable from a convex shape to a concave shape when the handle portion is pulled upward from the inside of the opening toward the outside while the cover portion is already deformed into a convex shape.

[0019] Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. However, the dimensions, materials, shapes, and relative arrangements of the components described below are merely exemplary and should be appropriately varied depending on the construction of the device to which the present invention is applied and various conditions. Therefore, the scope of the present invention is not intended to be limited to the following description. For constructions and processes not specifically shown or described, techniques known in the art or publicly known techniques may be applied. Furthermore, there are instances where repeated descriptions are omitted.

[0020] [First Embodiment]

[0021] The first embodiment of the present invention will now be described with reference to the accompanying drawings.

[0022] <Liquid injection device 200>

[0023] Figure 1 This is a perspective view showing the mechanism unit of the liquid injection device 200 to which this embodiment can be applied.

[0024] Figure 2 It is along Figure 1 A cross-sectional view of the liquid injection device 200 in line II-II. Figure 2For ease of explanation, the dimensions of some components have been changed or some components have been omitted. The liquid jetting device 200 includes a feeding unit 1, a conveying unit 2, a jetting unit 3, a supply unit 4, a display unit 5, a liquid storage container 16, and a container cover 7 covering the container storage unit configured to store the liquid storage container 16. The feeding unit 1 separates the printing media sheet by sheet from a bundle of sheet-like printing media using a feeding roller 10 and supplies it to the conveying unit 2. The conveying unit 2 is located downstream of the feeding unit 1 in the conveying direction and includes a pressure plate 13 for holding the printing media between the conveying roller unit 11 and the sheet discharge roller unit 12. The conveying unit 2 conveys the printing media fed from the feeding roller 10 using the conveying roller unit 11, the sheet discharge roller unit 12, etc.

[0025] The ejection unit 3 ejects liquid onto the printing medium via a liquid ejection head 15 mounted on a carriage 14. The printing medium, conveyed by the transport unit 2, is supported vertically below the printing medium by a pressure plate 13. Then, liquid is ejected from the liquid ejection head 15, located vertically above the printing medium, to form an image based on image information. A liquid storage container 16 stores the liquid. The supply unit 4 is configured to supply liquid from the storage chamber 100 of the container body 111 via a flow path 101 and a flexible supply tube 17 to the liquid ejection head 15. In this embodiment, the liquid is ink. Specifically, four supply tubes 17 through which various colors of ink (black, magenta, cyan, and yellow) flow extend from the liquid storage container 16. The supply tubes 17 extending from the liquid storage container 16 are connected to the liquid storage container 16 and the liquid ejection head 15 in a bundled manner. When the liquid supplied to the liquid ejection head 15 is ejected from the ejection port of the liquid ejection head 15, the same amount of liquid as the ejected liquid is supplied from the liquid storage container 16 to the liquid ejection head 15. Then, in the liquid storage container 16, air of the same amount as the liquid supplied to the liquid nozzle 15 flows in from the air vent 102 located vertically above the container body 111. The display unit 5 is used to notify the user of the device's operational status and to display information when the user selects an operation.

[0026] <Liquid replenishment>

[0027] Figure 3 This is a perspective view showing the replenishment of liquid from the liquid replenishment container 201 to the liquid injection device 200. (See image.) Figure 3As shown, in the liquid injection device 200 of this embodiment, when supplying liquid, the user opens the container cap 7 and supplies liquid from the liquid replenishment container 201 to the interior of the storage chamber 100 via the supply port 106 included in the liquid storage container 16. A cap member 105, configured to be detachably attached to the container body 111 and to seal the supply port 106, is attached to the supply port 106. When replenishing liquid through the liquid replenishment container 201, the user removes the cap member 105 from the supply port 106. With such a configuration, when the container cap 7 is opened and the cap member 105 is removed, liquid can be supplied to the interior of the liquid injection device 200 while the liquid storage container 16 is stored in a container storage unit provided within the body of the liquid injection device 200. The configuration of the liquid storage container 16 is not limited to the configuration in this embodiment where the liquid storage container 16 is incorporated into the body of the liquid injection device 200. As long as liquid can be supplied from the liquid storage container 16 to the liquid injection head 15, the construction of the liquid storage container 16 being located outside the main body of the liquid injection device 200 is also acceptable.

[0028] <Liquid Storage Container 16>

[0029] Figure 4 This is a perspective view showing the liquid storage container 16 of the liquid injection device 200. The liquid storage container 16 of this embodiment includes: a container body 111, which includes a storage chamber 100 and a supply port 106; and a cover member 105. The container body 111 is formed of a synthetic resin such as polypropylene and has a generally rectangular parallelepiped shape. The container body 111 has a front wall 1010, a right wall 1020, a left wall 1030, a top wall 1040, and a bottom wall 1050. The front wall 1010 includes an upright wall 1010A extending generally in a vertical direction from the bottom wall 1050, and an inclined wall 1010B (an example of an outer wall) connected to the top of the upright wall 1010A and inclined relative to the vertical and front-back directions. The inclined wall 1010B is inclined towards the rear relative to the upright wall 1010A. Furthermore, a liquid supply port 106 is formed in the inclined wall 1010B.

[0030] On the other hand, the back side of the container body 111 is open. Then, the membrane 1060 is welded to the rear ends of the right wall 1020, left wall 1030, first color partition 1021, second color partition 1022, third color partition 1023, top wall 1040, and bottom wall 1050, sealing the container body 111 and forming the rear wall as the back side. That is, the rear wall of the container body 111 is formed through the membrane 1060. With the above structure, a storage chamber 100 for storing liquid is formed.

[0031] <Comparative Example>

[0032] To make the cover member 105 according to this embodiment easy to understand, the plug member 905 according to the comparative example will be described first.

[0033] Figure 5 This is a cross-sectional view of the plug member 905 according to the comparative example. In the description of the plug member 905, the same names or the same symbols are used for structures that are the same as or correspond to the structure in this embodiment. Figure 5 As shown, the plug member 905 includes: a main body portion 905C, which is located outside the storage chamber 100 and the supply port 106 when the plug member 905 is attached to the supply port 106; and a plug portion 905D, which is inserted into the supply port 106 and blocks the supply port 106.

[0034] Typically, the plug member 905 is elastic. When the plug member 905 is attached to the supply port 106, the plug portion 905D is inserted into the supply port 106 while elastically deforming. Then, after the plug portion 905D is inserted, the plug portion 905D presses the supply port 106 from the inside to the outside by the elastic restoring force. Therefore, the plug member 905 enters a state where the plug member 905 is tightly fitted into the supply port 106. Furthermore, the main body portion 905C of the plug member 905 includes a cover portion 905B that covers the open surface of the supply port 106, and a handle portion 905A that protrudes from the top surface 904 of the cover portion 905B. The handle portion 905A is also the part that the user grips when removing the plug member 905 from the supply port 106. The user opens the supply port 106 by pulling the handle portion 905A to pull the plug member 905 out of the supply port 106. Figure 5 As shown, the handle portion 905A is formed to protrude from the top surface 904 of the cover portion 905B along the open surface of the supply port 106 when the plug member 905 is attached to the supply port 106. In the plug member 905 of the comparative example, the inner surface 907 is substantially horizontal relative to the open surface of the supply port 106. In this case, it may sometimes occur that an adhering substance Q (e.g., ink in the liquid storage container 16) adheres to the inner surface 907 of the cover portion 905B and remains there due to its stickiness. For example, if the adhering substance Q is ink, and the ink remains on the inner surface 907 due to its stickiness, the ink is more likely to scatter when the user pulls the plug member 905 out of the supply port 106. Furthermore, if the user touches the inner surface 907 after removing the plug member 905, there is a possibility that ink may adhere to the user's hands. The above is a description of the plug member 905 according to the comparative example. Hereinafter, the cover member 105 according to this embodiment will be described.

[0035] <Cover component 105>

[0036] Figure 6A and Figure 6BThese are all cross-sectional views of the cover member 105 in this embodiment. The cover member 105 is a member corresponding to the plug member 905 described above. Figure 6A and Figure 6B The cross-sectional view of the cover member 105 shown corresponds to the cross-sectional view of the plug member 905. Furthermore, Figure 6A and Figure 6B The vertical direction and Figure 5 The top and bottom directions are consistent. Figure 6A The cover component 105 is along Figure 4 A cross-sectional view of the VI-VI line. Figure 6B It is shown Figure 6A The diagram shows the deformed state of the cover member 105. As described above, the liquid storage container 16 has a container body 111. The container body 111 has a supply port 106.

[0037] like Figure 6A As shown, the liquid storage container 16 has a cover member 105 that can be attached to and detached from the supply port 106 (i.e., opened). The cover member 105 has a cover portion 600 that can cover the supply port 106. In the schematically shown example, the cover portion 600 has a frustoconical shape. Furthermore, the open surface of the supply port 106 is configured to be inclined relative to the direction of gravity. The cover portion 600 includes a first region 601, a second region 602, and a third region 603. When the cover member 105 is attached to the supply port 106, the first region 601 is configured to lie along the open surface of the supply port 106 and cover a portion of the open surface of the supply port 106. In the schematically shown example, the first region 601 is annular in shape. When the cover member 105 is attached to the supply port 106, the second region 602 is located in a direction in which the second region 602 becomes further away from the supply port 106 relative to the position of the first region 601. In this embodiment, the second region 602 is configured to be substantially horizontal relative to the open surface of the supply port 106. Furthermore, the second region 602 is located inside the inner periphery of the first region 601. In the schematic example shown, the second region 602 is circular in shape.

[0038] Furthermore, as schematically shown, the cap member 105 has a handle portion 605 that protrudes from the cap member 105 in a direction that moves further away from the supply port 106. Specifically, in the state where the cap member 105 is attached to the supply port 106, the handle portion 605 protrudes substantially perpendicularly from the surface of the second region 602 in a direction that moves further away from the supply port 106. The state in which the handle portion 605 "protrudes" is such that the handle portion 605 protrudes sufficiently to allow the user to apply force to the handle portion 605 by pinching and pulling or pushing it. Additionally, the handle portion 605 is configured to protrude from the surface of the second region 602 at a position through which the axis CP passing through the center of the cap member 105 passes when the liquid storage container 16 is in the position of being removed from the supply port 106. Preferably, the handle portion 605 has a rib 606. The rib 606 has one or more grooves in the side of the handle portion 605. When the user removes the cover component 105 and hooks his / her fingers around the side of the handle portion 605, the rib 606 functions to increase the friction between the side of the handle portion 605 and the fingers. The third region 603 connects the inner periphery of the first region 601 and the outer periphery of the second region 602. That is, the first region 601, the second region 602, and the third region 603 are formed continuously.

[0039] Furthermore, when the cover member 105 is attached to the supply port 106, the reverse face 607 of the cover member 105 is exposed towards the inside of the container body 111. Then, when the cover member 105 is removed from the supply port 106, the reverse face 607 is shaped as a recess formed by the reverse face of the second region 602, the reverse face of the third region 603, and the reverse face of the first region 601. Therefore, even if an adhering substance Q adheres to the reverse face 607 when the cover member 105 is removed from the supply port 106, the reverse face of the third region 603 and the reverse face of the first region 601 still face towards the inside of the cover member 105. Therefore, when the cover member 105 is removed from the supply port 106, it is possible to suppress the adhering substance Q from scattering to the outside of the cover member 105. Therefore, the liquid storage container 16 according to this embodiment can reduce the possibility of liquid scattering when the cover member 105 is removed. Furthermore, it is also possible to reduce the possibility of liquid adhering to the user after the cover member 105 is removed.

[0040] However, when the cover component 105 is in Figure 6AIn the state shown (hereinafter appropriately referred to as the "first state"), the total height of the cover member 105, including the handle portion 605, may be greater than the height of the plug member 905 according to the comparative example. Therefore, there is a possibility that the handle portion 605 may collide with the inner side of the container cover 7, and the container cover 7 may not be able to be closed. When attempting to maintain a gap from the top of the handle portion 605 to the inner side of the container cover 7 in order to close the container cover 7, sometimes there may be no alternative but to widen the container storage section in the liquid injection device 200 for storing the liquid storage container 16. That is, with the cover member 105 remaining in the first state, the size of the liquid injection device 200 may increase as a result.

[0041] <Deformation of cover component 105>

[0042] Therefore, in order to close the container lid 7, the lid member 105 according to this embodiment can also be designed to be deformable, such as... Figure 6B As shown below, Figure 6B The state shown is appropriately referred to as the "second state". In such a configuration, the cover 600 has a first groove 611 at the boundary between the first region 601 and the third region 603. Furthermore, the cover 600 has a second groove 612 at the boundary between the second region 602 and the third region 603.

[0043] Furthermore, the materials constituting the third region 603, the first groove 611, and the second groove 612 include flexible materials. This is because the third region 603 needs to be bent when the cover member 105 deforms from the first state to the second state or when the cover member 105 deforms from the second state to the first state.

[0044] Furthermore, compared to the regions where the first groove 611 and the second groove 612 are not formed, the regions where the first groove 611 and the second groove 612 are formed have weaker resistance to force. Therefore, when the first groove 611 and the second groove 612 are formed in the cover portion 600, the third region 603 can be bent with less force compared to the cases where the first groove 611 and the second groove 612 are not formed. That is, when the cover member 105 deforms, the third region 603 can be bent starting from the first groove 611 and the second groove 612. Therefore, when the first groove 611 and the second groove 612 are formed in the cover portion 600, it is easier to deform the cover member 105. Furthermore, it is preferable that the materials constituting the third region 603, the first groove 611, and the second groove 612 include plastic materials. This is because, when using the liquid injection device 200, maintaining the second state of the cover member 105 is more conducive to the miniaturization of the liquid injection device 200. For example, the materials constituting the third region 603, the first groove 611, and the second groove 612 include rubber.

[0045] Furthermore, the second region 602 differs in thickness from the first region 601 and the third region 603. Specifically, the second region 602 is thicker than the first region 601 and the third region 603. When the user deforms the cover member 105, the handle portion 605 protruding from the second region 602 is operated by the user. When the cover member 105 is deformed by the user from the first state to the second state, the handle portion 605 is pushed from the outside of the supply port 106 inward. Furthermore, when the cover member 105 is deformed by the user from the second state to the first state, the handle portion 605 is pulled upward from the inside of the supply port 106 outward. As described above, in this embodiment, the user operates the handle portion 605, thus a load is applied to the second region 602. In order to make the second region 602 durable against the load applied when the user operates the handle portion 605, the second region 602 is constructed to be thicker than the first region 601 and the third region 603. In addition, because the second region 602 is thicker, the handle 605 is easier to operate.

[0046] Furthermore, when the cover member 105 deforms from the first state to the second state, the handle portion 605, the second region 602, and the third region 603 move from the outside to the inside of the supply port 106. Therefore, in the second state, the second region 602 is located inside the supply port 106. Thus, the length of the handle portion 605 protruding from the supply port 106 in the second region 602 can be reduced. That is, in the second state, the height of the cover member 105 is smaller than the height in the first state, thus reducing the overall size of the liquid storage container 16. Therefore, the liquid storage container 16 can be stored in the liquid injection device 200 without increasing the size of the liquid injection device 200. Additionally, when the user replenishes liquid in the liquid storage container 16, the cover member 105 is detached from the supply port 106. The handle portion 605 has a length that allows it to protrude from the supply port 106 when the cover portion 600 is deformed into a convex shape (i.e., when the cover portion 600 is deformed to the second state). Thus, the user can deform the cover member 105 from the second state to the first state by pinching and pulling the part of the handle 605 that protrudes from the supply port 106.

[0047] <Disassembly of cover component 105>

[0048] Figures 7A to 7C All are cross-sectional views showing the disassembly process of the cover member 105 in this embodiment. Figures 7A to 7C Each of the above is a cross-sectional view showing the process of removing the cover member 105 from the supply port 106 of the container body 111. The process of removing the cover member 105 will be described below. Figures 7A to 7C Arrow P in the diagram indicates the direction in which cover component 105 is disassembled from supply port 106.

[0049] Figure 7A The second state of the cover member 105 is shown. (As shown) Figure 7A As shown, in the second state, the third region 603 and the second region 602 form a protrusion extending inward from the outside of the supply port 106. Furthermore, for some reason, an adhering substance Q is attached to the inner side 607 of the cover portion 600 (see...). Figure 6A and Figure 6B (The situation is as follows.)

[0050] Figure 7B It shows Figure 7A The cover member 105 shown has been deformed from the second state to the first state. (As...) Figure 7B As shown, when the cover member 105 is in the second state, and the user pulls the handle portion 605 upward from the inside to the outside of the supply port 106, the cover member 105 deforms from the second state to the first state. At this time, as the cover member 105 deforms from the second state to the first state, the third region 603 and the second region 602, which have already formed protrusions, form a recess that is recessed from the inside to the outside of the supply port 106 in the first state. Then, in this state, the inner side 607 enters a state where it covers the attachment Q from the outside. In the example shown schematically, by deforming the cover member 105 from the second state to the first state, the attachment Q enters a state where it is pulled into the recess formed by the third region 603 and the second region 602. Then, the attachment Q is held in the recess by its adhesiveness.

[0051] Figure 7C The cover member 105 is shown from Figure 7B Move upwards to the position shown. Figure 7C The state of the position shown. By further following the direction of arrow P from Figure 7B Pull the handle 605 upwards at the indicated position, and the cover component 105 is removed from the supply port 106.

[0052] Summary

[0053] With the cover member 105 attached to the opening, the cover portion 600 can deform into a convex shape when the handle portion 605 is pushed from the outside of the opening towards the inside. Furthermore, with the cover portion 600 already deformed into a convex shape, when the handle portion 605 is pulled upwards from the inside of the opening towards the outside, the cover portion 600 can deform from a convex shape to a concave shape. Therefore, even if an adhering substance Q adheres to the inner surface 607, the adhering substance Q will remain on the already deformed concave inner surface 607. Therefore, the liquid storage container 16 according to this embodiment can reduce the possibility of liquid spillage when the cover member 105 is removed.

[0054] Furthermore, in the event that the handle 605 collides with the container lid 7 when closing the lid 7, it is only necessary to deform the lid member 105 from the first state to the second state. This suppresses liquid spillage when the lid member 105 is removed and enables miniaturization of the liquid storage container 16. In other words, the liquid storage container 16 according to this embodiment can suppress liquid spillage while preventing the liquid spraying device 200 from becoming too large.

[0055] [Second Embodiment]

[0056] Hereinafter, this embodiment will be described with reference to the accompanying drawings. The basic structure of this embodiment is the same as that of the first embodiment; therefore, the characteristic structures will be described below. Furthermore, the orientation in the drawings showing the cover member 105 of the embodiment to be described later is the same as that in the first embodiment. The object of this embodiment is to provide a liquid storage container that improves operability when the cover member 105 is deformed.

[0057] Figure 8 This is a cross-sectional view of the cover member 105 according to this embodiment. (See figure) Figure 8 As shown, in this embodiment, the material constituting the handle portion 605 is different from the material constituting the cover portion 600. Specifically, the handle portion 605 according to this embodiment is constructed using a material with higher rigidity than the cover portion 600 according to this embodiment.

[0058] With the handle portion 605 being rigid, it is easier for the user to operate the handle portion 605 when pushing or pulling it. That is, according to the liquid storage container having the handle portion 605 according to this embodiment, operability when deforming the cover member 105 can be improved.

[0059] [Third Embodiment]

[0060] The third embodiment of the present invention will now be described with reference to the accompanying drawings. The basic structure of this embodiment is the same as that of the first embodiment; therefore, the characteristic features will be described below. The object of this embodiment is to provide a liquid storage container that can further improve operability when the cover member 105 is deformed.

[0061] Figure 9 This is a cross-sectional view of the cover member 105 according to this embodiment. (See figure) Figure 9 As shown, according to this embodiment, the cover member 105 has a diameter larger than the diameter of the handle portion 605 (in... Figure 9 The first top surface 1001 (with a greater length in the left-right direction) is preferably made of a rigid material. This is because a rigid first top surface 1001 makes it easier for the user to grip it.

[0062] With such a configuration, it is easier for the user to hook their fingers by pinching the first top surface 1001 when pulling the handle 605 upwards. Furthermore, compared to the first embodiment, the area touched by the user when pushing the handle 605 can be increased in this embodiment. Therefore, it is easier for the user to push the handle 605. Thus, the operability of the liquid storage container 16 having the first top surface 1001 when deforming the cover member 105 can be further improved.

[0063] [Fourth Embodiment]

[0064] Hereinafter, this embodiment will be described with reference to the accompanying drawings. The basic structure of this embodiment is the same as that of the first embodiment, therefore, the characteristic structure will be described below. The object of this embodiment is to provide a liquid storage container 16 capable of suppressing excessive deformation of the cover member 105.

[0065] Figure 10 This is a cross-sectional view of the cover member 105 according to this embodiment. (See figure) Figure 10 As shown, the cover member 105 has a second top surface area 1002 with an area larger than that of the supply port 106. Preferably, the material constituting the second top surface area 1002 includes a rigid material. This is because a rigid second top surface area 1002 makes it easier for the user to grip it.

[0066] According to such a configuration, the area of ​​the second top surface 1002 is wider than the area of ​​the supply port 106. Therefore, even if the user excessively pushes the handle 605, even if the handle 605 passes through the first region 601, the movement of the handle 605 stops when the inner side of the second top surface 1002 collides with the supply port 106. Therefore, the liquid storage container 16 according to this embodiment, in addition to the aforementioned improvement in operability, can also suppress excessive deformation of the cover member 105 caused by excessive pushing of the handle 605.

[0067] [Fifth Embodiment]

[0068] Hereinafter, this embodiment will be described with reference to the accompanying drawings. The basic structure of this embodiment is the same as that of the first embodiment, therefore, the feature structure will be described below. The object of this embodiment is to provide a liquid storage container 16 that can deform the cover member 105 even if the user forgets to deform the cover member 105 from the first state to the second state.

[0069] Figure 11 This is a cross-sectional view showing how the lid member 105 is deformed from a first state to a second state via the container lid 7. (As shown) Figure 11As shown, the container lid 7 has a structure in which the handle portion 605 can be pushed when the user moves the container lid 7 in the direction of closing the container lid 7. Furthermore, the handle portion 605 of the lid member 105 has a length that allows the handle portion 605 to collide with the inner side of the container lid 7 when the container lid 7 is closed in the first state. Preferably, the area of ​​the closed container lid 7 that can be pushed is increased by using a second top surface portion 1002.

[0070] With such a configuration, when closing the container lid 7, the user can deform the lid member 105 from a first state to a second state by causing the inner side of the container lid 7 to collide with the second top surface 1002. Therefore, the lid member 105 can be deformed even if the user forgets to deform it from the first state to the second state. Even without using the first top surface 1001 or the second top surface 1002, the handle 605 can be pushed by using the container lid 7.

[0071] [Sixth Embodiment]

[0072] Hereinafter, this embodiment will be described with reference to the accompanying drawings. The basic structure of this embodiment is the same as that of the first embodiment, therefore, the characteristic structure will be described below. The object of this embodiment is to provide a liquid jetting device 200 that can further suppress liquid scattering.

[0073] Figure 12 This is a perspective view of the container lid 7 according to this embodiment. Figure 12 As shown, the container cap 7 of the liquid injection device 200 according to this embodiment has a mounting unit 107 on its inner side, in which the cap member 105, which is detached from the supply port 106, is mounted. Furthermore, preferably, the mounting unit 107 has a liquid absorption section 108. Examples of materials constituting the liquid absorption section 108 include fibrous polymers and liquid-permeable components. Specifically, the material constituting the liquid absorption section 108 includes polyurethane. Examples of polyurethane foam are also mentioned.

[0074] Therefore, when the cover member 105 is removed from the supply port 106, the liquid absorption section 108 can absorb the liquid adhering to the inner side surface 607. Thus, in this embodiment, by having the liquid absorption section 108 absorb the liquid adhering to the inner side surface 607 each time the cover member 105 is removed, it is easier to maintain the state where the adhering substance Q does not adhere to the inner side surface 607. Therefore, the liquid spraying device 200 according to this embodiment can further suppress liquid scattering.

[0075] [Other Embodiments]

[0076] In the first embodiment, examples of materials used to constitute the cover member 105 include those with plasticity, but the material constituting the cover member 105 may include those with elasticity. With such a configuration, the user can cause the cover member 105, which contracts when the container lid 7 is closed, to deform from the second state to the first state using elastic restoring force when the container lid 7 is opened, without requiring any action from the user. Furthermore, with such a configuration, there is a possibility that adhering material Q attached to the inner side 607 may return into the container body 111 due to vibration when the cover member 105 deforms from the second state to the first state. Therefore, liquid spillage when the cover member 105 is removed from the supply port 106 can be suppressed.

[0077] The liquid storage container according to the present invention can reduce the possibility of liquid spillage when the cover component is removed.

[0078] Although the invention has been described with reference to exemplary embodiments, it should be understood that the invention is not limited to the disclosed exemplary embodiments. The scope of the appended claims should be given the broadest interpretation to cover all such modifications and equivalent structures and functions.

[0079] This application claims the benefit of Japanese Patent Application No. 2022-064147, filed on April 7, 2022, which is incorporated herein by reference in its entirety.
