JP 2016-13663 A

In recent years, ink packs (also called liquid containers) have been placed in trays with open tops, and the trays are then inserted into printing devices.

It is also known that if the printing device continues to suck ink even though the remaining amount of ink contained in the liquid container is decreasing, the liquid container can become deformed.

When attempting to pull out the above-mentioned tray from the printing device, if the liquid container is deformed and warped, the liquid container may get caught on the printing device.

The present disclosure therefore aims to prevent warping of liquid containers.

The liquid mounting body of the present disclosure comprises a liquid container having a bag for containing liquid and a liquid supply port for supplying the liquid contained in the bag, and a tray for containing the liquid container, wherein the tray comprises a space consisting of a top surface with an opening, a bottom surface on which the liquid container is placed, one side surface on which the liquid supply port is located, another side surface opposite the one side surface, and two side surfaces connecting the one side surface and the other side surface, a visor-shaped restricting portion extending from the upper edge of the other side surface toward the space, a plate-shaped first rib connecting the bottom surface to one of the two side surfaces, and a plate-shaped second rib connecting the bottom surface to the other of the two side surfaces, and the bag of the liquid container is made of film, and a processed portion for assisting in valley folding of the bag body is formed on the surface of the bag body from the liquid supply port side to the opposite side.

This disclosure makes it possible to prevent the liquid container from warping upward.

<Embodiment 1>
[Liquid ejection device 100]
Hereinafter, an embodiment of the present disclosure will be described with reference to the drawings. Fig. 1 is a perspective view of a liquid ejection device 100. The liquid ejection device 100 of this embodiment prints images using an inkjet method on a print medium such as roll paper based on print data transmitted from an information processing device such as a personal computer or a mobile terminal. The liquid ejection device 100 includes a tray 11 as a container for accommodating ink packs 10 (described below).

The tray 11 contains ink packs 10 as liquid containers. For convenience, the structure consisting of the tray 11 and ink packs 10 is referred to as the liquid mounting body 1. The ink packs 10 are detachable from the tray 11. The liquid ejection device 100 also includes a recording head (not shown), a recording medium storage section (not shown), a recording medium transport mechanism (not shown), etc.

[About dimensions]
Regarding the dimensions in the figure, the Y direction, X direction, and Z direction are mutually orthogonal. The Y direction will be described first. The Y direction in the figure indicates the movement direction of the tray 11 constituting the liquid mounting body 1. In the following description, the tray 11 will be described as the object of movement, so that movement when the ink packs 10 are not stored in the tray 11 is also included. When removing the tray 11 from the liquid ejection device 100, the tray 11 is pulled out in the -Y direction. On the other hand, when attaching the tray 11 to the liquid ejection device 100, the tray 11 is inserted in the +Y direction. The Y direction also indicates the length direction of the ink packs 10 and the tray 11. In this embodiment, the direction in which the tray 11 is inserted into the liquid ejection device 100 is referred to as the base end side of the tray 11. In other words, the +Y direction side in the figure is the base end side of the tray 11. On the other hand, the -Y direction side is referred to as the tip end side of the tray 11.

Next, we will explain the X direction in the figure. In this embodiment, the X direction refers to the width direction of the ink pack 10 and the tray 11. In this embodiment, the left direction is referred to as the -X direction, based on the direction in which the tray 11 is inserted into the liquid ejection device 100 (i.e., the +Y direction). On the other hand, the right direction is referred to as the +X direction, based on the direction in which the tray 11 is inserted into the liquid ejection device 100 (i.e., the +Y direction).

Next, we will explain the Z direction in the figure. In this embodiment, the Z direction refers to the height direction of the ink pack 10 and the tray 11. In this embodiment, the direction of gravity is used as the reference, and the direction of gravity is referred to as the -Z direction. On the other hand, the direction against gravity is referred to as the +Z direction.

[Regarding the ink pack 10]
The ink pack 10 contains a liquid therein. An example of the liquid is ink ejected from the recording head of the liquid ejection device 100. Note that, in this embodiment, the liquid is described as ink, but examples of the liquid are not limited to ink.

In this embodiment, the liquid ejection device 100 is equipped with four trays 11. One ink pack 10 is stored in each tray 11. Examples of the ink colors mentioned above include cyan (C), magenta (M), yellow (Y), and black (K). In this embodiment, the four ink packs 10 are assumed to be the same size, and the following explanation will continue.

The ink pack 10 is also stored so that it contacts the bottom surface of the tray 11, which will be described later.

[Regarding Tray 11]
2, 3, 4, and 6 show the configuration of the tray 11 without the regulating unit 17, which will be described later. To make it easier to understand the contents of the tray 11 with the regulating unit 17, a comparative example (a tray 11 without the regulating unit 17) will be described first.

Figure 2 is a plan view of the tray 11. As described above, the tray 11 is a component of the liquid ejection device 100, and functions as a container capable of housing the ink packs 10. In this embodiment, the top surface (the surface facing the +Z direction) of the tray 11 is open, allowing the ink packs 10 to be housed therein in a removable manner from the +Z direction (see Figure 1).

The tray 11 can also be removably attached to the mounting portion of the liquid ejection device 100 even when it does not contain an ink pack 10. The tray 11 is attached to the mounting portion by being inserted in the +Y direction of the liquid ejection device 100. On the other hand, when removing the tray 11 from the liquid ejection device 100, it is pulled out in the -Y direction. In this case, the user typically grasps the side of the tray 11 that is furthest in the -Y direction and pulls the tray 11 out of the liquid ejection device 100 in the -Y direction.

Figure 3 is a cross-sectional view taken along line III-III. As shown in Figure 3, the tray 11 has a bottom surface and side surfaces that rise from the left and right sides of the bottom surface (-X direction and +X direction) toward the anti-gravity direction (+Z direction).

[Storage of ink pack 10]
Fig. 4 is a plan view of the tray 11 in which the ink pack 10 is stored. As shown in Fig. 4, the ink pack 10 can be stored in the tray 11. The ink pack 10 also includes a film portion 12 as a liquid containing bag, an adapter 19, and an ink supplying component 20 as a liquid supplying component. The ink supplying component 20 is contained in the area of the film portion 12 indicated by the dashed line in the figure.

The ink supply component 20 includes a spout that supplies ink from the film portion 12 to the liquid ejection device 100, a spacer that prevents the opposing inner surface 13 (described below) from coming into close contact, and a suction port that sucks ink from the film portion 12. The ink supply component 20 also includes a tube that transports ink sucked by the suction port toward the spout, and a shaft that connects the spacer and the spout. In other words, the ink supply component 20 is a component that includes all of the components required to supply ink from the film portion 12 to the liquid ejection device 100. When the tray 11 containing the ink packs 10 is inserted into the liquid ejection device 100, the film portion 12 and the liquid ejection device 100 are connected via the adapter 19. This allows the ink from the film portion 12 to be supplied to the liquid ejection device 100 via the spout.

[Regarding the film portion 12]
The film portion 12 is formed by welding the peripheral edges of the first film 14 and the second film 15. Details of the first film 14 and the second film 15 will be described later. The film portion 12 is formed by heat welding or the like from a flexible film into a bag shape. The shape of the film portion 12 is preferably a pillow type or a three-sided type, which becomes more flat when all the ink is consumed. However, the shape is not necessarily limited to the pillow type or the three-sided type, and a gusset type or other type may also be used.

A two-layer film can be used as the flexible film. For example, a polyethylene layer, which has ink wettability and excellent thermal weldability, can be provided on the inside of the film portion 12. Here, ink wettability refers to the property that the component is not affected (hardened, embrittled, or corroded) when it comes into contact with ink, and the components contained in the component are not dissolved in the ink.

Furthermore, a film with low gas permeability, such as an aluminum vapor deposition film or aluminum laminate film with an aluminum layer, can be used on the outside of the film portion 12. Note that it does not necessarily have to be a two-layer film; a single-layer film is also acceptable.

[Regarding adapter 19]
The adapter 19 connects the base end of the ink pack 10 to the base end of the tray 11. For example, when the ink pack 10 is housed in the tray 11 and the tray 11 is inserted into the liquid ejection device 100, the adapter 19 and the liquid ejection device 100 are connected. This makes it possible to supply the ink in the film portion 12 of the ink pack 10 to the liquid ejection device 100.

The adapter 19 has a liquid outlet section (not shown) for leading the ink in the film section 12 to the liquid ejection device 100. The spout described above is attached to the liquid outlet section. In other words, the ink in the film section 12 is led from the liquid outlet section to the liquid ejection device 100. The adapter 19 may also have a liquid mixing chamber inside to make the ink concentration uniform.

[Regarding the ink supply part 20]
Fig. 5 is a plan view of the ink pack 10. As shown in Fig. 5, the ink pack 10 includes the film portion 12, the adapter 19, and the ink supply part 20 described above.

[Regarding warping of the ink pack 10]
Fig. 6 is a diagram showing a warped state of the ink pack 10. When the ink in the film portion 12 is consumed while the ink pack 10 is housed in the tray 11 inside the liquid ejection device 100, the film portion 12 begins to deform as shown in Fig. 6. Specifically, the area of the film portion 12 other than the area containing the ink supply component 20 gradually deforms.

As the liquid ejection device 100 continues to consume ink from the film portion 12, the first film 14 and second film 15 become tightly attached. Furthermore, as ink from the film portion 12 continues to be consumed while the first film 14 and second film 15 are in tight contact, the tightly attached portion warps. In other words, if no measures are taken to prevent this warping, the ink pack 10 may protrude from the tray 11 in the +Z direction.

If the ink pack 10 is warped inside the liquid ejection device 100 when the user replaces the ink pack 10, the ink pack 10 may become caught inside the liquid ejection device 100. If the user tries to forcefully pull out the tray 11 despite this, the film portion 12 may break, causing ink to leak. Below, we will explain the configuration that prevents this from happening.

[Regarding the restriction unit 17]
7 is a diagram showing a state in which warping of the ink pack 10 is suppressed. In the following description, the same reference numerals are used to designate configurations that are similar to or correspond to those in the comparative example described above, and a description will be omitted, with differences being mainly described.

As shown in Figure 7, the tray 11 according to this embodiment has side portions that face each other across the end where the liquid supply port of the ink pack 10 is located. The tray 11 has a three-dimensional shape with at least the top surface open, and is equipped with a restricting portion 17. Specifically, the tray 11 has a visor-shaped restricting portion 17 on the edge of the other end (-Y direction side) of the end (+Y direction side) where the liquid supply port of the ink pack 10 is located.

The restrictor 17 protrudes from the ceiling of the edge on the other end (-Y direction side) toward the end (+Y direction side) where the liquid supply port is located. A hollow space is formed between this protruding portion and the bottom surface of the tray 11.

As shown in the figure, the restricting portion 17 restricts the warping of the ink pack 10. In other words, the restricting portion 17 prevents the ink pack 10 from warping upward in the anti-gravity direction (+Z direction), thereby preventing the ink pack 10 from warping upward further. Hereinafter, the length of the restricting portion 17 extending in the Y direction will be referred to as the "eaves length."

If the "eaves length" is too long, the film portion 12 will interfere with the restricting portion 17 when the ink pack 10 is placed in the tray 11, making it difficult to place the ink pack 10. Conversely, if the "eaves length" is too short, the warped film portion 12 cannot be held in place. Therefore, it is desirable that the "eaves length" extend from the edge portion in the direction of the liquid supply port by a length that is 0.6 to 1.5 times the height from the bottom surface of the tray 11 to the top surface.

A more preferable range for the "eaves length" is one that extends at least 0.8 times the height of the tray 11, from the perspective of ensuring reliable warping prevention. Furthermore, from the perspective of reliable warping prevention and ensuring ease of use when storing the ink pack 10, the "eaves length" should be approximately 1.2 times the height of the tray 11. Of course, the above-mentioned "eaves length" is merely an example.

Regarding warping of the film portion 12 of the ink pack 10, the warping state shown in Figures 6 and 7 tends to occur most frequently. Specifically, the film portion 12 warps upward with a gradually increasing curvature from near the center to the tip (-Y direction side).

For this reason, as shown in Figure 8 below, it is desirable that the restricting portion 17 be formed across the left side surface (the side surface located on the -X direction side) and the right side surface (the side surface located on the +X direction side) of the tray 11. Furthermore, in manufacturing the tray 11 according to this embodiment, the restricting portion 17 provided on the tray 11 is molded integrally with the tray 11.

As a result, with the tray 11 according to this embodiment, the curling of the film portion 12 of the ink pack 10 is stopped by the restricting portion 17, thereby preventing the ink pack 10 from curling up. In other words, when the tray 11 is pulled out from the liquid ejection device 100, the ink pack 10 is prevented from getting caught inside the liquid ejection device 100, allowing the tray 11 to be pulled out smoothly.

<Embodiment 2>
A second embodiment of the technology of the present disclosure will now be described with reference to the drawings. Fig. 8 is a diagram showing a state in which warping of the ink pack 10 is suppressed in this embodiment. The tray 11 according to this embodiment differs from the tray 11 according to the first embodiment in the presence or absence of ribs 18. The direction in which the ink pack 10 bends is also different. In the following description, components similar to or corresponding to those in the first embodiment will be given the same reference numerals and will not be described again, with the differences being mainly described.

In embodiment 1, we have described a case where the ink pack 10 warps upward, but the ink pack 10 does not always warp upward. Because various factors affect the bending of the film portion 12 of the ink pack 10, the film portion 12 can bend in various directions. For example, the film portion 12 can bend in a valley fold or a mountain fold with respect to the length direction (Y direction).

Therefore, in situations where it is unclear whether the film portion 12 will bend upward or downward, it may be better to actively guide the ink pack 10 in the bending direction and assist the ink pack 10 in bending. Therefore, in this embodiment, we will describe a tray 11 and ink pack 10 that are equipped with a structure that assists the ink pack 10 in bending in a valley fold.

[Storage of ink pack 10 in this embodiment]
Figure 8 is a plan view of the tray 11 containing the ink packs 10 according to this embodiment. As shown in Figure 8, in this embodiment, the tray 11 is provided with six ribs 18 in total, three on each side. The size of the ribs 18 is, for example, 14 mm wide and 10 mm high. Of course, the number and size of the ribs 18 are merely examples. The installation positions and number of the ribs 18 provided on the tray 11 may be changed as appropriate, taking into consideration the dimensions of the film portion 12 and/or the amount of ink contained in the film portion 12.

As described above, in this embodiment, recesses 16 are formed on the surface of the first film 14. As shown in the figure, two recesses 16 are formed linearly on the surface of the first film 14, running from the base end to the tip end of the film portion 12. Furthermore, the recesses 16 are formed in positions that do not interfere with the ink supply component 20 contained in the film portion 12. Specifically, one recess 16 is formed outside the area that contains the ink supply component 20, and one recess 16 is formed inside each of the two end portions of the film portion 12. In other words, it is desirable that the recesses 16 be formed in positions that do not interfere with the ink supply component 20.

[Regarding the Bending of the Ink Pack 10 in the Present Embodiment]
9 is a diagram showing a state in which bending of the ink pack 10 according to this embodiment is suppressed. As shown in Fig. 9, the tray 11 according to this embodiment includes a rib 18. The restricting portion 17 is formed across both side surfaces of the tray 11, similar to the first embodiment.

In addition, a recess 16 is formed on the surface of the first film 14 of the ink pack 10 according to this embodiment. As shown in the figure, the film portion 12 of the ink pack 10 according to this embodiment bends in a valley shape (towards the +Z direction) starting from the recess 16, and this bending is restricted by restricting portions 17 provided on both side surfaces of the tray 11. In other words, the film portion 12 of the ink pack 10 is prevented from bending upward above the height of the side surfaces (to prevent bending in the anti-gravity direction).

[Regarding the rib 18 in this embodiment]
10 is a plan view of the tray 11 in this embodiment. In this embodiment, the example shown in this drawing shows a total of six ribs 18. The ribs 18 in this embodiment will be described below.

Figure 11 is a cross-sectional view taken along line XI-XI. As shown in Figure 11, the rib 18 has a slope formed from the side to the bottom of the tray 11. By providing the tray 11 with the rib 18 with this slope, when an ink pack 10 is placed in the tray 11 and ink is consumed, the valley fold of the ink pack 10 can be guided along the slope of the slope. In other words, the slope formed on the rib 18 helps the film portion 12 described above to fold upward in the anti-gravity direction.

By folding the ink pack 10 in a valley, the ink remaining inside the film portion 12 is gathered in the direction of the ink supply component 20 of the film portion 12. This makes it easier for the suction port of the ink supply component 20 to suck up the ink, and also improves the ease of using up the ink.

Figure 12 is a cross-sectional view taken along line XII-XII. As mentioned above, the tray 11 has a total of six ribs 18. This drawing shows three ribs 18 on the right side (+X direction side) of the tray 11.

[Ink pack 10 in this embodiment]
13 is a plan view of the ink pack 10 according to this embodiment. As mentioned above, this drawing shows two recesses 16. The recesses 16 will now be described.

[Regarding the recess 16]
14 is a cross-sectional view taken along line XIV-XIV. First, the configuration of the film portion 12 according to this embodiment will be described. As shown in FIG. 14, the film portion 12 includes a first film 14 and a second film 15.

In this embodiment, recesses 16 are formed on the surface of the first film 14. The recesses 16 are formed by embossing. Therefore, the embossed surface of the first film 14 becomes recesses 16, while the inner surface of the embossed portion becomes protrusions. One example of the configuration of the first film 14 is one in which the thickness is 0.1 mm. On the other hand, the second film 15, as shown in the figure, is not embossed. The first film 14 and the second film 15 have inner surfaces that face each other, and these inner surfaces that face each other are referred to as opposing inner surfaces 13.

Next, we will explain how the film portion 12 according to this embodiment bends. As described above, the recesses 16 are continuously formed on the surface of the first film 14 from the base end to the tip end of the first film 14. As a result, when the film portion 12 deforms as ink is consumed, the film portion 12 bends (folds up) in a valley fold starting from the recesses 16.

As a result, with the tray 11 and ink pack 10 according to this embodiment, both left and right sides of the film portion 12 of the ink pack 10 can be folded in a valley fold direction, starting from the recess 16. The regulating portion 17 can then prevent this valley fold (folding upward). In other words, in this embodiment as well, when the tray 11 is pulled out from the liquid ejection device 100, the ink pack 10 is prevented from getting caught inside the liquid ejection device 100, allowing the tray 11 to be pulled out smoothly.

<Embodiment 3>
A third embodiment of the technology of the present disclosure will now be described with reference to the drawings. FIG. 15 is a plan view of the tray 11 in this embodiment. The difference between the tray 11 in the first embodiment and the tray 11 in this embodiment is the position at which the restricting portion 17 is formed. In the following description, the same reference numerals will be used to designate components similar to or corresponding to those in the first embodiment, and a description thereof will be omitted, with the focus being on the differences. In the first embodiment, the restricting portion 17 was formed across both side surfaces of the tray 11. In contrast, in this embodiment, the restricting portion 17 is formed at a corner between the end (+Y direction side) where the liquid supply port of the ink pack 10 is located and the other end (-Y direction side) of the tray 11.

This makes it easier for the user to hook their fingers on the wall portion that includes the restricting portion 17 when pulling the tray 11 out of the liquid ejection device 100. Furthermore, compared to embodiment 1, the restricting portion 17 can be formed using less material. Furthermore, when the film portion 12 of the ink pack 10 is valley-folded as in embodiment 2, only the left and right ends of the film portion 12 that are folded up by the valley fold can be held down, so no material is wasted. As a result, the tray 11 according to this embodiment can prevent the ink pack 10 from warping up using less material.

<Fourth Embodiment>
A fourth embodiment of the technology disclosed herein will now be described with reference to the drawings. FIG. 16 is a diagram showing a state in which warping of the ink pack 10 is suppressed in this embodiment. The difference between the tray 11 according to the first embodiment and the tray 11 according to this embodiment is the height at which the restricting portion 17 is formed. In the following description, the same reference numerals will be used to designate components similar to or corresponding to those in the first embodiment, and a description thereof will be omitted, with the focus being on the differences. In the first embodiment, the restricting portion 17 extended from the top of the wall surface located at the most distal end (negative Y direction side) of the tray 11 (i.e., the highest position in the Z direction) toward the proximal end (positive Y direction side).

In contrast, in this embodiment, the restricting portion 17 extends from the middle of the wall surface located at the tip end (negative Y direction side) of the tray 11 toward the base end (positive Y direction side). This makes it easier for the user to hook their finger on the wall surface portion where the restricting portion 17 is provided when pulling the tray 11 out of the liquid ejection device 100. In other words, the tray 11 according to this embodiment can be pulled out more smoothly while preventing the ink packs 10 from warping up.

<Other embodiments>
In the above example, the recesses 16 were described assuming that all ink packs 10 were the same size, but the size of the ink packs 10 that contain a specific color may be changed. For example, the ink pack 10 for black (K), which is consumed frequently, may be made larger, up to the size that can be accommodated in the tray 11. In this case, it is desirable to form one recess 16 on each side of the black (K) ink pack 10, 15 to 20 mm inward from each of the left and right end portions.

In the above example, the restricting portion 17 contacts a corner of the tray 11 located on the -Y direction side, but the restricting portion 17 does not necessarily need to contact the corner of the tray 11. For example, the restricting portion 17 does not need to reach the corner of the tray 11, as long as it has a sufficient width in the X direction and is wide enough to substantially prevent the film portion 12 of the ink pack 10 from curling up.

Regarding the molding of the restricting portion 17, the above example shows the restricting portion 17 being molded integrally with the tray 11, but the restricting portion 17 and the tray 11 may also be molded separately. For example, if it is difficult to mold the restricting portion 17 and the tray 11 at the same time, the restricting portion 17 may be molded separately and then joined to the tray 11. The joining method may be welding (thermal welding, etc.) or bonding with an adhesive.

Regarding the ribs 18, the above example shows an example in which the tray 11 is equipped with ribs 18, but the inside of the side of the tray 11 may be sloped to guide the valley folds of the film portion 12 in the ink pack 10, to the extent that this is possible.
