Description

  The present invention relates to a tray and the like.

Conventionally, an ink jet printer is known as an example of a liquid ejecting apparatus. In general, an ink jet printer can print on a printing medium by ejecting ink, which is an example of a liquid, from a print head toward various printing media such as paper and fabric. 2. Description of the Related Art Conventionally, an ink jet printer is known in which an ink stored in a liquid container is supplied to a print head. As a liquid container, a configuration in which ink is stored in a flexible bag-like pack is known. Conventionally, a tray that can accommodate such a pack is known (see, for example, Patent Document 1).

JP 2007-83497 A

According to the tray described in the said patent document 1, the impact concerning the pack accommodated in the tray can be relieved. However, when the pack has a gusset portion, a gap is easily generated between the pack and the tray in the gusset portion. For this reason, the pack accommodated in the tray tends to swing in the tray. When the pack contained in the tray is repeatedly swung in the tray,
It is conceivable that the pack is damaged due to friction between the pack and the tray or fatigue of the pack. That is, the conventional tray has a problem that it is difficult to improve the reliability of the liquid container that contains the liquid.

The present invention can solve at least the above-described problems and can be realized as the following forms or application examples.

Application Example 1 A tray capable of storing a liquid container that contains a liquid, the liquid container including a liquid container configured in a bag shape with a flexible film material, and the liquid container The part is formed with a gusset part that becomes concave toward the inside of the liquid storage part, and the tray is
A tray having a side portion opposed to the gusset portion in a state in which the liquid container is accommodated, and a convex portion protruding toward the gusset portion is provided on the side portion.

In this tray, a convex portion that protrudes toward the gusset portion is provided on a side portion of the liquid storage portion that faces the gusset portion. Thereby, the clearance gap between a liquid storage part and a tray can be reduced in a gusset part. For this reason, the liquid container accommodated in the tray is unlikely to swing within the tray. Therefore, it is easy to suppress the occurrence of friction between the liquid container and the tray, fatigue of the liquid container, and the like. As a result, in this tray, the reliability of the liquid container can be easily improved.

Application Example 2 In the above tray, when the liquid container is stored in the tray,
The tray, wherein the convex portion is in contact with the gusset portion.

In this tray, when the liquid container is accommodated in the tray, the convex portion comes into contact with the gusset portion, so that the gap between the liquid storage portion and the tray can be further reduced in the gusset portion.

Application Example 3 In the tray described above, the protruding amount of the convex portion from the side portion is larger than the depth dimension of the concave gusset portion.

  In this tray, the convex portion can be reliably brought into contact with the gusset portion.

Application Example 4 In the tray described above, the protrusion amount of the convex portion is equal to 10/7 times the depth dimension of the gusset portion, or 10 / of the depth dimension of the gusset portion. A tray characterized by exceeding 7 times.

  In this tray, the convex portion can be reliably brought into contact with the gusset portion.

Application Example 5 In the above tray, the gusset portion includes a fold that can fold the gusset portion, and a curved portion provided on a virtual line that intersects the fold, and the convex portion is The tray is opposed to at least a crossing portion of the gusset portion where the fold line and the virtual line intersect.

In this tray, the convex portion faces at least an intersection portion of the gusset portion where the fold line and the virtual line intersect. Here, in the liquid storage portion in which the gusset portion has a fold and a bent portion, the portion where the fold of the gusset portion and the bent portion provided on the imaginary line of the gusset portion easily get tired. In this tray, since the convex portion faces the intersecting portion, damage due to fatigue of the liquid storage portion can be easily suppressed.

Application Example 6 In the tray described above, the liquid storage portion is formed with the two gusset portions facing each other, and the tray is configured to store the liquid container in a state where the liquid storage body is stored. The tray is characterized in that the convex portion is provided on each of the side portions facing each of the gusset portions.

In this tray, a gap between the liquid storage portion and the tray can be reduced in two gusset portions facing each other. For this reason, the liquid container accommodated in the tray is less likely to swing in the tray.

Application Example 7 In the tray described above, the liquid container contains the liquid supplied to the liquid ejecting apparatus that ejects the liquid, and can contact an electrical connection portion of the liquid ejecting apparatus. A tray having an electrical contact portion.

In this tray, since the liquid container accommodated in the tray is difficult to swing in the tray, it is easy to protect the electrical contact portion provided in the liquid container.

A portion that is located at an end portion in the −V-axis direction of 7 and extends along the U-axis is denoted as a joint portion 68B. On the other hand, as described above, the portion of the joint portion 68 that is located at the end portion in the V-axis direction of the ink containing portion 67 and extends along the U-axis is the joint portion 68A. In FIG. 15, the joints 68 </ b> A and 68 </ b> B are hatched for easy understanding of the configuration.

The shoulder portion 151 is a portion that intersects the joint portion 68 </ b> A except for the gusset portion 71. Similarly, the shoulder portion 152 is a portion that intersects the joint portion 68 </ b> B except for the gusset portion 71. The shoulder portion 151 and the shoulder portion 152 are on both the W axis direction side of the gusset portion 71 and the −W axis direction side of the gusset portion 71, respectively. In other words, the ink containing portion 67 has two shoulder portions 151 and two shoulder portions 152.
The two shoulder portions 151 are in positions where they face each other with the gusset portion 71 in between. Similarly, the two shoulder portions 152 are also located at positions facing each other with the gusset portion 71 interposed therebetween. In the following description, when the two shoulders 151 are distinguished from each other, the two shoulders 151 are referred to as a shoulder 151A and a shoulder 151B (not shown), respectively.

It protrudes from the side part 144 toward the side part 143, that is, from the side part 144 in the U-axis direction. In the following, when the two convex portions 156 are distinguished from each other, the two convex portions 156 are referred to as a convex portion 156A and a convex portion 156B, respectively. Convex part 15 of two convex parts 156
6A is located on the inclined portion 142 side from the convex portion 156B, that is, in the V-axis direction from the convex portion 156B.

In the present embodiment, the convex portion 155A and the convex portion 156A are provided at positions facing each other along the U axis. Further, the convex portion 155B and the convex portion 156B are provided at positions facing each other along the U axis. As shown in FIG. 19, the two convex portions 155 are located in the W-axis direction with respect to the bottom portion 145 of the concave portion 137. That is, there is a gap between the two convex portions 155 and the bottom portion 145. For this reason, the two convex portions 155 are each provided in an island shape at the side portion 143. Similarly, there is a gap between the two convex portions 156 and the bottom portion 145. For this reason, each of the two convex portions 156 is also provided in an island shape at the side portion 144.

When the pack unit 65 is accommodated in the tray 135, the two convex portions 155 are respectively
It faces the intersecting portion 79 (FIG. 5) of the gusset portion 71 (71A) of the ink containing portion 67.

With the above configuration, the gap between the ink containing portion 67 and the tray 135 in the gusset portion 71 can be reduced. For this reason, the pack unit 65 accommodated in the tray 135 is unlikely to swing within the tray 135. Therefore, it is easy to suppress friction between the ink containing portion 67 and the tray 135, impact on the ink containing portion 67, and the like. Further, since the deformation of the gusset portion 71 is easily suppressed by the convex portion 155 and the convex portion 156, it is possible to suppress the fatigue of the ink containing portion 67 due to repeated deformation of the gusset portion 71 to a low level. As a result, this tray 1
In 35, the reliability of the pack unit 65 can be easily improved.

In the present embodiment, when the pack unit 65 is accommodated in the tray 135, the two convex portions 15

In the present embodiment, when the pack unit 65 is accommodated in the tray 135, the two convex portions 15
The five and two convex portions 156 contact the intersecting portion 79 of the gusset portion 71 of the ink containing portion 67, respectively. Here, the gusset portion 71 includes an ink storage portion 67 having a crease 73 and a curved portion 76.
A portion where the crease 73 of the gusset portion 71 and the curved portion 76 provided on the imaginary line 78 of the gusset portion 71 intersect easily fatigues. On the other hand, in the tray 135, since the convex portion 155 and the convex portion 156 face the intersecting portion 79, damage due to fatigue of the ink containing portion 67 can be easily suppressed.

Further, in the present embodiment, as shown in FIG. 20, when the depth dimension of the gusset part 71 is D1, and the protrusion amount from the side part 143 and the side part 144 of the convex part 155 and the convex part 156 is H1. The protrusion amount H1 is larger than the depth dimension D1. Thereby, the convex part 155 and the convex part 156 can be made to contact the gusset part 71 reliably. For this reason, it is easier to suppress friction between the ink containing portion 67 and the tray 135, impact on the ink containing portion 67, and the like. In addition, it is possible to further suppress the fatigue failure of the ink containing portion 67.

Moreover, in this embodiment, depth dimension D1 and protrusion amount H1 are following (1) Formula or (2).
The relationship of the formula is satisfied.
H1 = D1 × 10/7 (1)
H1> D1 × 10/7 (2)
Thereby, the convex part 155 and the convex part 156 can be made to contact the gusset part 71 reliably.
For this reason, it is easier to suppress friction between the ink containing portion 67 and the tray 135, impact on the ink containing portion 67, and the like. In addition, it is possible to further suppress the fatigue failure of the ink containing portion 67. In the present embodiment, by setting the protrusion amount H1 to 10 mm and the depth dimension D1 to 7 mm, the destruction of the ink containing portion 67 can be suppressed to a very low level.
