The present invention relates to a bottle set and the like.
Examples of hitherto known ink ejection apparatuses include inkjet printers capable of printing on a recording medium, such as recording paper, using ink by discharging the ink from a recording head to the recording medium. Some inkjet printers allow a user to refill a tank for storing ink that is to be supplied to the recording head. Bottles with which ink can be injected into a tank are hitherto known (e.g. see Chinese Examined Utility Model Publication No. 202186122).
Chinese Examined Utility Model Publication No. 202186122 discloses a bottle set having a bottle capable of containing ink, and a lid member that is removable from the bottle. In this bottle set, the bottle has a discharge port, which is formed to discharge the contained ink. The lid member in the bottle set covers the discharge port in a state where the lid member is attached to the bottle. In this bottle set, a sealing member for sealing the discharge port is put between the lid member and the discharge port. Thus, the bottle can be sealed with the lid member attached to the bottle. However, in this bottle set, the sealing member is interposed between the lid member and the discharge port. This configuration accordingly makes it difficult to reduce the number of parts of the known bottle set.
The invention can solve at least the above problem, and may be realized as the following modes or application examples.
A bottle set according to one embodiment includes a bottle and a lid member. The bottle has an ink container configured to contain ink, a nozzle through which the ink in the ink container is configured to flow out, and a joint portion integrally formed with the nozzle and having a thread configured to engage the nozzle with the ink container. The lid member is attachable to and detachable from the bottle, and configured to cover the nozzle in a state where the lid member is attached to the bottle. An outflow port is formed in the nozzle. The outflow port is configured such that the ink in the ink container flows out from the outflow port. The lid member has a tubular barrel, a top plate that closes a barrel end of the tubular barrel, and a plug projecting from the top plate toward the nozzle. A distance from the barrel end of the tubular barrel to a distal end of the plug being shorter than a distance from a nozzle end of the nozzle to the joint portion.
The invention will be described with reference to the accompanying drawings, wherein like numbers reference like elements.
An embodiment will be described while taking an ink ejection system as an example, with reference to the drawings. Note that, in the drawings, the scale of constituent parts and members may be different such that the respective constituent parts are shown with a recognizable size.
As shown in
Hereinafter, the X axis, Y axis, and Z axis that appear in the drawings and descriptions depicting constituent parts and units of the ink ejection system 1 mean the X axis, Y axis, and Z axis in a state where the constituent parts and units are assembled with (mounted in) the ink ejection system 1. The posture of the constituent parts and units when the ink ejection system 1 is in the use state will be called a use posture of these constituent parts and units. In the following description, the ink ejection system 1, the constituent parts and units thereof, and the like in their use posture will be described unless otherwise stated.
The Z axis is an axis perpendicular to the XY plane. When the ink ejection system 1 is in the use state, the Z-axis direction is a vertically upward direction. Also, when the ink ejection system 1 is in the use state, the −Z-axis direction is a vertically downward direction in
In the printer 3, the recorder 6 and the controller 9 are housed in the housing 11. The recorder 6 performs recording using ink as one example of liquid on a recording medium P, which is conveyed in the Y-axis direction by a conveying apparatus (not shown). Note that the conveying apparatus (not shown) intermittently conveys the recording medium P, such as recording paper, in the Y-axis direction. The recorder 6 is configured to be able to be moved back and forth along the X axis by a moving apparatus (not shown). An ink supply apparatus 4 supplies the ink to the recorder 6. The controller 9 controls driving of the aforementioned constituent parts.
Here, a direction parallel with the X axis is not limited to a direction that is perfectly parallel with the X axis, and also includes a direction that tilts relative to the X axis due to an error, a tolerance, or the like, excluding a direction perpendicular to the X axis. Similarly, a direction parallel with the Y axis is not limited to a direction that is perfectly parallel with the Y axis, and also includes a direction that tilts relative to the Y axis due to an error, a tolerance, or the like, excluding a direction perpendicular to the Y axis. A direction parallel with the Z axis is not limited to a direction that is perfectly parallel with the Z axis, and also includes a direction that tilts relative to the Z axis due to an error, a tolerance, or the like, excluding a direction perpendicular to the Z axis. That is to say, a direction parallel to an axis or a plane is not limited to a direction that is perfectly parallel with this axis or plane, and also includes a direction that tilts relative to this axis or plane due to an error, a tolerance, or the like, excluding a direction perpendicular to this axis or plane.
The recorder 6 includes a carriage 17 and a recording head 19. The recording head 19 is an example of an ink ejector, and discharges droplets of the ink to perform recording on the recording medium P. The recording head 19 is mounted in the carriage 17. Note that the recording head 19 is electrically connected to the controller 9. Discharge of ink droplets from the recording head 19 is controlled by the controller 9.
The ink supply apparatus 4, which is an example of a tank unit, includes tanks 31, each of which is an example of an ink supply unit, as shown in
The ink is contained in each tank 31. An ink injection portion 33 is formed in each tank 31. The ink can be injected into each tank 31 from outside via the ink injection portion 33. Note that an operator can access the ink injection portion 33 of the tank 31 from outside the housing 32. The ink injection portion 33 is sealed by a lid (not shown). When the ink is injected into each tank 31, a lid is removed to open the ink injection portion 33, and thereafter the ink is injected.
Ink supply tubes 34 are connected to the respective tanks 31. The ink in each tank 31 is supplied to the recording head 19 from the ink supply apparatus 4 via the corresponding ink supply tube 34. The ink supplied to the recording head 19 is discharged as ink droplets from nozzles (not shown), which are oriented toward the recording medium P side. Note that, although the above example describes the printer 3 and the ink supply apparatus 4 as separate constituent parts, the ink supply apparatus 4 may be included in the constituent parts of the printer 3.
In the ink ejection system 1 having the above configuration, recording is performed onto the recording medium P by conveying the recording medium P in the Y-axis direction, and causing the recording head 19 to discharge ink droplets at a given position while moving the carriage 17 back and forth along the X axis. This operation is controlled by the controller 9.
The ink is not limited to either one of water-based ink or oil-based ink. Water-based ink may be either ink having a configuration in which a solute, such as a dye, is dissolved in a water-based solvent, or ink having a configuration in which a dispersoid, such as a pigment, is dispersed in a water-based dispersing medium. Oil-based ink may be either ink having a configuration in which a solute, such as a dye, is dissolved in an oil-based solvent, or ink having a configuration in which a dispersoid, such as a pigment, is dispersed in an oil-based dispersing medium.
In this embodiment, a bottle set 35 shown in
The lid member 42, when in a state of being attached to the bottle 41, is configured to be able to cover the nozzle 44. The nozzle 44 can also be defined as a portion that is covered by the lid member 42 when the lid member 42 is attached to the bottle 41. A later-described outflow port is formed in the nozzle 44. The ink in the ink container 43 flows out of the bottle 41 from the outflow port in the nozzle 44. The lid member 42, when in a state of being attached to the bottle 41, covers the outflow port in the nozzle 44.
Note that the lid member 42 may be engaged with the nozzle 44 via a thread 46 formed on the nozzle 44, as shown in
In this embodiment, the bottle 41 includes a container member 47 and a nozzle member 48, as shown in
Note that the number of parts to constitute the bottle 41 is not limited to two, namely the container member 47 and the nozzle member 48. The number of parts to constitute the bottle 41 may be three or more. Also, the number of parts to constitute the bottle 41 may be one. When the bottle 41 is constituted by one part, this part can be formed by integrally molding resin, for example.
Various examples of the bottle set 35 and members that constitute the bottle set 35 (hereinafter referred to as constituent members) will be described. Note that, in the following description, different alphabetical characters, symbols, or the like will be appended to the signs of the bottle set 35 and the constituent members in the respective examples in order to identify the bottle set 35 and the constituent members in the respective examples.
A bottle set 35A in Example 1 includes a container member 47, a nozzle member 48A, and a lid member 42A, as shown in
The container member 47 is configured to be able to contain the ink. The container member 47 and the nozzle member 48A are configured to be separate bodies. A thread 51 is formed in the nozzle member 48A. The container member 47 and the nozzle member 48A are configured to be engageable with each other using the thread 49 on the container member 47 and the thread 51 in the nozzle member 48A. The container member 47 and the nozzle member 48A are also configured to be attachable to and detachable from each other. By relatively twisting (turning) the nozzle member 48A with respect to the container member 47, the nozzle member 48A can be removed from the container member 47.
The ink is contained in the container member 47. The container member 47 is made of an elastic material. As shown in
The nozzle member 48A may be divided into a joint portion 55 and the nozzle 44, as shown in
The nozzle 44 projects from the joint portion 55 to the side opposite to the container member 47 side. The nozzle 44 has a pipe-like shape. A guiding flow passage 57 is formed inside the nozzle 44. The guiding flow passage 57 is provided in an area that overlaps the area of the opening 54 when seen in a plan view. The guiding flow passage 57 is a hollow area in the nozzle 44, the area overlapping the area of the opening 54 when seen in a plan view. An outflow port 59 is formed at an end 58 of the nozzle 44 on the side opposite to the joint portion 55 side. The outflow port 59 is open toward the side opposite to the joint portion 55 side in the nozzle 44. The outflow port 59 is open at the end 58. Thus, the end 58 surrounds the outflow port 59. The outflow port 59 is located at a terminal of the guiding flow passage 57.
The ink contained in the container member 47 can flow out from the outflow port 59 through the guiding flow passage 57 in the nozzle 44. As a result, the ink in the container member 47 may flow out of the container member 47 from the outflow port 59 through the opening 54 and the guiding flow passage 57. When a user injects the ink in the bottle 41A into the corresponding tank 31, the outflow port 59 is inserted into the ink injection portion 33 of the tank 31. The user then injects the ink in the container member 47 into the tank 31 from the ink injection portion 33. Note that, when the user injects the ink in the bottle 41A into the tank 31, the user removes the lid member 42A (
The nozzle 44 includes an engaging portion 61, as shown in
The lid member 42A is made of an elastic material, and may be divided into a tubular barrel 62 and a plate-shaped top plate 63, as shown in
The barrel 62 and the top plate 63 are integrally formed. In the bottle set 35A (
A thread 64 is provided in an inner side face of the barrel 62. The barrel 62 is a part to be engaged with the nozzle member 48A (
Here, an abutting portion 65 is provided in the top plate 63 of the lid member 42A, as shown in
In this example, the distance (depth) from an end 66 of the barrel 62 to the top plate 63 is shorter (shallower) than the distance from the joint portion 55 to the end 58 of the nozzle member 48A (
With this configuration, the outflow port 59 can be sealed. Thus, in the case where, for example, the ink in the container member 47 cannot be entirely injected into the tank 31 and some ink remains in the container member 47, the ink can be stored in the bottle 41A with the outflow port 59 closed by the lid member 42A. This configuration allows the ink to be stored with an increased airtightness in the container member 47 after being opened. As a result, it is possible to suppress evaporation of liquid components of the ink in the bottle 41A and degradation of the ink. Note that the abutting portion 65 is an example of a sealing portion. In this example, the abutting portion 65 for sealing the outflow port 59 of the nozzle 44 is integrally formed in the lid member 42A. Thus, in this bottle set 35A, the outflow port 59 in the nozzle 44 can be sealed with the lid member 42A. With this configuration, the number of parts can be reduced compared with a configuration in which the outflow port 59 is sealed by adding other members to the lid member 42A.
Furthermore, in this example, the thickness of the abutting portion 65 is formed to be smaller than the thickness of the other part of the lid member 42A. Thus, as shown in
A bottle set 35B in Example 2 includes a container member 47, a nozzle member 48A, and a lid member 42B, as shown in
The lid member 42B may be divided into a barrel 62 and a top plate 63 similarly to the lid member 42A in Example 1, as shown in
The plug 71 is an example of a sealing portion, and is provided in the top plate 63 on the nozzle member 48A (
In this example, as shown in
This configuration enables the outflow port 59 to be sealed. Thus, in the case where, for example, the ink in the container member 47 cannot be entirely injected into the tank 31 and some ink remains in the container member 47, the ink can be stored in the bottle 41A with the outflow port 59 closed by the lid member 42B. Thus, the ink can be stored with an increased airtightness in the container member 47 after being opened. As a result, it is possible to suppress evaporation of liquid components of the ink in the bottle 41A and degradation of the ink. In this example, the plug 71 for sealing the outflow port 59 of the nozzle 44 is integrally formed in the lid member 42B. Thus, in this bottle set 35B, the outflow port 59 in the nozzle 44 can be sealed with the lid member 42B. As a result, the number of parts can be reduced compared with a configuration in which the outflow port 59 is sealed by adding other members to the lid member 42B. As shown in
A bottle set 35C in Example 3 includes a lid member 42C and a bottle 41A, as shown in
In Example 1, the inside of the lid member 42A is a space 74 to be closed by the lid member 42A and the nozzle member 48A, as shown in
In Examples 1 and 2, the space 74 tends to be highly airtight. When the space 74 is highly airtight, the pressure in the space 74 easily changes due to a change in the environment temperature, the atmospheric pressure, or the like. If the pressure in the space 74 changes, the lid member 42 easily deforms, for example. If the lid member 42 deforms, it is conceivable that the lid member 42 easily comes off the bottle 41 or easily gets damaged. If the lid member 42A in Example 1 deforms, the adhesion between the abutting portion 65 and the end 58 of the nozzle 44 degrades, and the ink easily leaks out from the nozzle 44, for example. If the lid member 42B in Example 2 deforms, a gap is easily formed between the plug 71 and the outflow port 59, and the ink easily leaks out from the nozzle 44.
In Example 3, the communicating hole 73 is formed in the barrel 62, which facilitates mitigation of a change in the pressure in the space 74. Thus, deformation of the lid member 42 can be suppressed. As a result, leakage of the ink from the nozzle 44 can be suppressed.
Example 3 employs a configuration in which the air in the space 74 can be released by the lid member 42C in which the communicating hole 73 is formed. However, the configuration that enables the air in the space 74 to be released is not limited thereto. The communicating portion capable of bringing the inside and the outside of the lid member 42 into communication with each other may also be a lid member 42D in which a slit 75 is formed in the barrel 62, as shown in
The slit 75 is formed to extend from the end 66 of the barrel 62 toward the top plate 63, and passes through the barrel 62. The slit 75 has a shape formed by cutting out the barrel 62 from the end 66 toward the top plate 63. In the lid member 42D in Example 4, the slit 75 allows the air in the space 74 to be readily released. Example 4 can also achieve the same effects as those achieved by Example 3. Note that the slit 75 in Example 4 is applicable to both the lid member 42A and the lid member 42B. Furthermore, the slit 75 is also applicable to the lid member 42C in Example 3.
The communicating portion capable of bringing the inside and the outside of the lid member 42 into communication with each other may also have a shape formed by cutting out a portion of the thread 64 provided in the inner side face of the barrel 62, as shown in
In the lid member 42E, the thread 64 is intermittently provided. In the lid member 42E, the thread 64 is not continuous, i.e. is not formed continuously. That is to say, the lid member 42E has a portion where the thread 64 is discontinuous. In Example 5, the air in the space 74 is readily released via a portion formed by cutting out a portion of the thread 64, i.e. a portion where the thread 64 is discontinuous. Example 5 can also achieve the same effects as those achieved in Examples 3 and 4.
Note that the thread 64 in Example 5 is applicable to both the lid member 42A and the lid member 42B. Furthermore, the thread 64 in Example 5 is also applicable to the lid member 42C in Example 3, and the thread 64 in Example 5 is also applicable to the lid member 42D in Example 4. The communicating hole 73 in Example 3 and the slit 75 in Example 4 are also applicable to the lid member 42E in Example 5.
As an example in which the air in the space 74 can be released, a nozzle member 48B may be employed as shown in
In the nozzle member 48B in Example 6, grooves 78 are formed at an end 77 of the joint portion 55. The end 77 is a boundary between the joint portion 55 and the nozzle 44, and is located on the nozzle 44 side of the joint portion 55, as shown in
A lid member 42F in Example 7 will now be described. In Example 7, constituent parts that are the same as those in Examples 1 to 6 will be assigned the same signs as those in Examples 1 to 6, and a detailed description thereof will be omitted. In Example 7, a gap is provided between a side face 81 of the barrel 62 of the lid member 42F and a side portion 61A of the engaging portion 61 of the nozzle member 48, as shown in
Example 7 is applicable to various dimensions of the engaging portion 61 within the area of the gap between the side face 81 and the side portion 61A, for example. That is to say, Example 7 is applicable to various nozzle members 48 with engaging portions 61 having different diameters. In Examples 2 to 6, the dimensions and shape of the barrel 62 are set in association with the diameter of the engaging portion 61. That is to say, one type of lid member 42 is required for one type of nozzle member 48. In contrast, in Example 7, one lid member 42F can be used for various nozzle members 48 with engaging portions 61 having different diameters. For this reason, the lid member 42F can be shared by a plurality of types of nozzle members 48, which can reduce the costs of the lid member 42F, and can also reduce the costs of the bottle set 35.
A lid member 42G in Example 8 will now be described. In Example 8, constituent parts that are the same as those in Examples 1 to 7 will be assigned the same signs as those in Examples 1 to 7, and a detailed description thereof will be omitted. In the lid member 42G, ribs 83, which project outward from the lid member 42G, are provided in an outer peripheral portion 82 of the barrel 62, as shown in
With the lid member 42G in Example 8, when the barrel 62 is placed on a floor or a desk, for example, the ribs 83 are likely to obstruct rolling of the barrel 62 on the surface. In addition, for example, when a user holds the lid member 42G with fingers to turn the lid member 42G, the ribs 83 are easily hooked at the fingers. Thus, the ribs 83 also achieves the effect of slip resistance or a handle. Note that the ribs 83 in Example 8 are applicable to any of Examples 1 to 7.
The bottle set 35 may also employ a configuration in which a film 85 is added to the container member 47, as shown in
With the bottle set 35 having the film 85, the film 85 can be set to stick out from the nozzle member 48 with the nozzle member 48 attached to the container member 47, as shown in
In contrast, if the film 85 is set to stick out from the nozzle member 48, the user can easily notice the film 85. Thus, the user is readily made to remove the film 85 from the container member 47 before injecting the ink in the bottle set 35 into the tank 31. As a result, it is possible to prompt the user to perform an operation to remove the film 85 from the container member 47 before injecting the ink into the tank 31. Thus, the convenience of the bottle set 35 can be improved.
In addition, if the film 85 is set to stick out from the nozzle member 48, the user can readily hold the film 85. Thus, the film 85 can be readily removed from the container member 47, which further improves the convenience of the bottle set 35. Also, a label can be added to a portion of the film 85 that sticks out from the nozzle member 48. The label may include information regarding the ink, such as ink color and main components thereof, and cautions regarding the handling, for example. Furthermore, color that indicates the ink color may also be added as the information regarding the ink. The label added to the film 85 can further improve the convenience of the bottle set 35. Addition of the label to the film 85 allows the user to more easily notice the film 85. As a result, the convenience of the bottle set 35 can be further improved.
In the above embodiment and examples, the ink ejection apparatus may be a liquid ejection apparatus that ejects, discharges, or applies liquid other than ink to consume the liquid. Note that the status of liquid discharged as very small droplets from the liquid ejection apparatus includes a granular shape, a tear-drop shape, and a shape having a thread-like trailing end. Furthermore, the liquid mentioned here may be any kind of material that can be consumed by the liquid ejection apparatus. For example, the liquid need only be a material whose substance is in the liquid phase, and includes fluids such as inorganic solvent, organic solvent, solution, liquid resin, and liquid metal (metal melt) in the form of a liquid body having a high or low viscosity, sol, gel water, or the like. Furthermore, the liquid is not limited to being a one-state substance, and also includes particles of a functional material made from solid matter, such as pigment or metal particles, that are dissolved, dispersed, or mixed in a solvent. Representative examples of the liquid include ink such as that described in the above embodiment, as well as liquid crystal, and the like. Here, “ink” encompasses general water-based ink and oil-based ink, as well as various types of liquid compositions such as gel ink and hot melt-ink. Specific examples of the liquid ejection apparatus include liquid ejection apparatuses that eject a liquid containing, in the form of dispersion or dissolution, a material such as an electrode material or a color material used in manufacturing or the like of a liquid crystal display, an EL (electro-luminescence) display, a surface-emitting display, or a color filter, for example. The liquid ejection apparatus may also be a liquid ejection apparatus that ejects biological organic matter used in manufacturing of a biochip, a liquid ejection apparatus that is used as a precision pipette and ejects a liquid serving as a sample, a textile printing apparatus, a microdispenser, or the like. Furthermore, the liquid ejection apparatus may also be a liquid ejection apparatus that ejects lubricating oil in a pinpoint manner to a precision machine such as a watch or a camera, or a liquid ejection apparatus that ejects a transparent resin liquid such as ultraviolet-cured resin onto a substrate in order to form a micro-hemispherical lens (optical lens) or the like that is used in an optical communication device or the like. Furthermore, the liquid ejection apparatus may be a liquid ejection apparatus that ejects an etchant which is acid, alkaline, or the like, in order to etch a substrate or the like.
According to one embodiment of the disclosure, a bottle set includes: a bottle having an ink container capable of containing ink, and a nozzle through which the ink in the ink container can flow out; and a lid member that is attachable to and detachable from the bottle, and can cover the nozzle in a state where the lid member is attached to the bottle, wherein an outflow port from which the ink in the ink container can flow out is formed in the nozzle, the lid member has a sealing portion that seals the outflow port in a state where the lid member is attached to the bottle, and the sealing portion is integrally formed in the lid member.
In this bottle set, the sealing portion for sealing the outflow port in the nozzle is integrally formed in the lid member. Thus, in this bottle set, the outflow port in the nozzle can be sealed with the lid member. As a result, the number of parts can be reduced compared with a configuration in which the outflow port is sealed with a member other than the lid member.
In the above-described bottle set, the sealing portion is provided as a plate-shaped abutting portion that comes into contact with a periphery of the outflow port to close the outflow port in a state where the lid member is attached to the bottle, and in the lid member, a thickness of the abutting portion is formed to be smaller than a thickness of another part of the lid member.
In this bottle set, the thickness of the abutting portion is smaller than the thickness of the other part of the lid member. Accordingly, the abutting portion readily undergoes elastic deformation when the abutting portion is caused to abut against the periphery of the outflow port. As a result, the abutting portion and the periphery of the outflow port are readily fitted closely to each other, which facilitates increasing the airtightness at the outflow port.
In the above-described bottle set, the sealing portion is provided as a plug that enters the outflow port to close the outflow port in a state where the lid member is attached to the bottle.
In this bottle set, the plug can be inserted into the outflow port when the lid member is attached to the bottle. Thus, the outflow port can be closed by the plug.
The above-described bottle set further including: a communicating portion capable of bringing inside and outside of the lid member into communication with each other in a state where the lid member is attached to the bottle.
In this bottle set, the inside and the outside of the lid member can be in communication with each other in a state where the lid member is attached to the bottle. Thus, a change in the pressure within the lid member can be mitigated.
In the above-described bottle set, the lid member is provided with a thread capable of engaging with the bottle, the lid member is configured to be able to be attached to the bottle through engagement using the thread, and the communicating portion has a shape formed by cutting out a portion of the thread.
In this bottle set, the communicating portion has a shape formed by cutting out a portion of the thread formed in the lid member. The inside and the outside of the lid member can be brought into communication with each other via the portion formed by cutting out a portion of the thread.
In the above-described bottle set, the communicating portion has a shape of a hole that is formed in the lid member and passes through the lid member to bring the inside and the outside thereof into communication with each other.
In this bottle set, the inside and the outside of the lid member can be brought into communication with each other via the hole that passes through the lid member to bring the inside and the outside thereof into communication with each other.
In the above-described bottle set, the communicating portion has a shape of a slit formed in the lid member.
In this bottle set, the inside and the outside of the lid member can be brought into communication with each other via the slit formed in the lid member.
In the above-described bottle set, a rib projecting outward from the lid member is formed in an outer peripheral portion of the lid member.
In this bottle set, the rib formed in the outer peripheral portion of the lid member can make it difficult for the lid member to roll around, for example.
Note that the invention is not limited to the above embodiment and examples, and can be achieved by various configurations without departing from the gist thereof. For example, the technical features in the embodiment and examples that correspond to the technical features in the modes described in the summary of the invention may be replaced or combined as appropriate in order to solve part or the entire foregoing problem, or to achieve some or all of the above-described effects. The technical features that are not described as essential in the specification can be deleted as appropriate.
