Description

This invention relates to a package for packaging rectangular polarizing plates.

Patent Document 1 describes a carrier box for loading and storing or transporting polarizing plates.
As shown in Figure 9, the carrier box 60 has a case body 61, a reference plate 62 arranged on the inner surface 61a of the case body 61, a guide rail portion 63 formed on the bottom surface 61b of the case body 61, and a slider 64 attached to the guide rail portion 63.

The reference plate 62 is disposed on two adjacent inner surfaces 61a among the four inner surfaces 61a erected from the bottom surface 61b of the case body 61. The guide rail portion 63 extends from a position on the two inner surfaces 61a on which the reference plate 62 is not disposed toward the two inner surfaces 61a on which the reference plate 62 is disposed. The slider 64 slides along the guide rail portion 63. The slider 64 also has a fixing means 65 for fixing the position on the guide rail portion 63.

When storing a polarizing plate (not shown) in the carrier box 60, two sides of the polarizing plate are brought into close contact with the surfaces of the two reference plates 62, and then each slider 64 is moved toward the reference plate 62 along the guide rail portion 63. Furthermore, with each slider 64 in contact with the remaining two sides of the polarizing plate, the position of each slider 64 is fixed with a fixing means 65, thereby fixing the position of the polarizing plate. By having the sliders 64, it is possible to store the polarizing plate in the case body 61 even if the size of the polarizing plate to be stored is changed.

The following is a detailed explanation of the embodiments of the present invention. Note that the scope of the present invention is not limited to the embodiments described here, and various modifications can be made without departing from the spirit of the present invention.

As shown in FIGS. 1 and 2, a package 10 of the present invention is used to package a rectangular polarizing plate 11 .
The polarizing plate 11 may include, for example, a laminate of a plurality of polarizing plates wrapped in a film. The number of polarizing plates in the laminate may be, for example, about 200 to 300. The length of one side of one polarizing plate may be, for example, 5 cm to 35 cm.

The package 10 includes a container 20 having a bottom wall portion 21 and a side wall portion 22, a lid 23 attached to the container 20, a cushioning material 30 disposed on the inner circumference of the side wall portion 22, and a pair of support members 50 disposed on the bottom wall portion 21 to support the polarizing plate 11. Note that the configuration of the package 10 does not include the polarizing plate 11.

(container)
As shown in FIGS. 1 to 3, the container 20 has a rectangular bottom wall portion 21 and a side wall portion 22 extending from the outer periphery of the bottom wall portion 21 in the stacking direction of the polarizing plate 11 .

(lid)
1 , the lid 23 has a rectangular top wall 24 and a peripheral wall 25 extending from the outer periphery of the top wall 24 in the thickness direction of the top wall 24. When the lid 23 is attached to the container 20, the peripheral wall 25 covers the outer periphery of the side wall portion 22 of the container 20.

The material of the lid 23 and the container 20 is not particularly limited, and paper or resin can be used. Among these, resin is preferable because it is durable and easy to make lightweight. In addition, transparent resin is preferable because it makes it easy to check the inside.

(Cushioning material)
1 to 3, the cushioning material 30 is configured in a long plate shape. The cushioning material 30 has a pair of first cushioning materials 31 arranged on the inner periphery of the side wall portion 22 on the long side of the bottom wall portion 21 of the container 20, and a pair of second cushioning materials 32 arranged on the inner periphery of the side wall portion 22 on the short side of the bottom wall portion 21 of the container 20.

One longitudinal end of the pair of first cushioning materials 31 is located at a corner of the side wall portion 22 of the container 20, and the other longitudinal end is close to another corner of the side wall portion of the container 20. Note that, in the pair of first cushioning materials 31, the one longitudinal end and the other longitudinal end of each first cushioning material 31 are located in opposite directions to each other.

One longitudinal end of the pair of second cushioning materials 32 is located at a corner of the side wall portion 22 of the container 20, and the other longitudinal end abuts one end of the first cushioning material 31. Note that, in the pair of second cushioning materials 32, the one longitudinal end and the other longitudinal end of each second cushioning material 32 are located in opposite directions to each other.

1, a rectangular plate-like buffer material 40 is further disposed above the polarizing plate 11. The outer shape of the buffer material 40 is substantially the same as the outer shape of the polarizing plate 11.
There is no particular limitation on the material of the first buffer material 31, the second buffer material 32, and the plate-shaped buffer material 40, and for example, foamed resin may be used. A specific example of foamed resin is foamed urethane resin.

(Support member)
3, the package 10 includes a pair of support members 50 disposed on the bottom wall portion 21 to support the polarizing plate 11. One of the pair of support members 50 is referred to as a first support member 51, and the other is referred to as a second support member 52. The first support member 51 and the second support member 52 have the same shape.

As shown in Figures 3 and 4, the first support member 51 has a first partition wall 51a arranged between the first side 11a and the second cushioning material 32 of the first side 11a and the second side 11b that extend across one corner of the polarizing plate 11. The first support member 51 also has a second partition wall 51b arranged between the second side 11b and the first cushioning material 31. The first support member 51 also has a first support wall 51c that is connected to both the first partition wall 51a and the second partition wall 51b and is arranged between the bottom wall portion 21 and the polarizing plate 11.

As shown in FIG. 7, the first support wall 51c extends horizontally from the ends of the first partition wall 51a and the second partition wall 51b on the bottom wall portion 21 side, and has a triangular shape in a plan view. The first support wall 51c has a substantially triangular through hole 51d in the center that is slightly smaller than the outer shape of the first support wall 51c.

As shown in Figures 3 and 4, the second support member 52 has a third partition wall 52a arranged between the third side 11c and the second cushioning material 32 of the third side 11c and the fourth side 11d that extend across the corner of the polarizing plate 11 at another corner located diagonally from the one corner of the polarizing plate 11. The second support member 52 also has a fourth partition wall 52b arranged between the fourth side 11d and the first cushioning material 31. The second support member 52 also has a second support wall 52c that is connected to both the third partition wall 52a and the fourth partition wall 52b and is arranged between the bottom wall portion 21 and the polarizing plate 11.

As shown in FIG. 7, the second support wall 52c extends horizontally from the ends of the third partition wall 52a and the fourth partition wall 52b on the bottom wall portion 21 side, and has a triangular shape in a plan view. The second support wall 52c has a substantially triangular through hole 52d in the center that is slightly smaller than the outer shape of the second support wall 52c.

As shown in FIG. 2, in the direction in which the first side 11a of the polarizing plate 11 extends, the length of the first partition wall 51a is shorter than the length of the first side 11a.
In the direction in which the second side 11b extends, the length of the second partition wall 51b is shorter than the length of the second side 11b.

In the direction in which the third side 11c extends, the length of the third partition wall 52a is shorter than the length of the third side 11c.
In the direction in which the fourth side 11d extends, the length of the fourth partition wall 52b is shorter than the length of the fourth side 11d.

As shown in Figures 4, 6, and 7, a plate member 53 is disposed on the underside of the first support wall 51c of the first support member 51 and on the underside of the second support wall 52c of the second support member 52. Here, the underside refers to the surface of the first support wall 51c and the second support wall 52c on the bottom wall portion 21 side. There are no particular limitations on the thickness of the plate member 53, but it is preferably 1 cm or more and 5 cm or less. Here, the thickness of the plate member 53 refers to the thickness in the stacking direction of the polarizing plate 11.

As shown in Figures 4 to 6, the first support member 51 has a first connection portion 54 to which the first partition wall 51a and the second partition wall 51b are connected. In other words, the first partition wall 51a and the second partition wall 51b are connected via the first connection portion 54. The first connection portion 54 has a notch 54a cut out so that the thickness becomes thinner from the inner periphery side of the first partition wall 51a and the second partition wall 51b that abuts against the polarizing plate 11 toward the outer periphery side. In other words, the first connection portion 54 has a notch 54a whose thickness becomes thinner in the direction away from the corner of the polarizing plate 11 when the polarizing plate 11 is supported on the first support member 51.

The first support wall 51c has grooves 51c1 at the boundary with the first partition wall 51a and at the boundary with the second partition wall 51b, where the thickness of the first support wall 51c is reduced.
7, the second support member 52 also has a second connection portion 55 where the third partition wall 52a and the fourth partition wall 52b are connected. The second connection portion 55 has a notch 55a cut out so that the thickness becomes thinner from the inner periphery side where the third partition wall 52a and the fourth partition wall 52b abut against the polarizing plate 11 toward the outer periphery side. In other words, the second connection portion 55 has the notch 55a whose thickness becomes thinner in the direction away from the corner of the polarizing plate 11 when the polarizing plate 11 is supported on the second support member 52.

The second support wall 52c has grooves 52c1 at the boundary with the third partition wall 52a and at the boundary with the fourth partition wall 52b, where the thickness of the second support wall 52c is reduced.
2, the first connection portion 54 has the notch 54a, which makes it possible to prevent the corners of the polarizing plate 11 from interfering with the first connection portion 54 when the polarizing plate 11 is supported by the first support member 51. Similarly, the second connection portion 55 has the notch 55a, which makes it possible to prevent the corners of the polarizing plate 11 from interfering with the second connection portion 55 when the polarizing plate 11 is supported by the second support member 52. As a result, defects such as chipping at the corners of the polarizing plate 11 can be prevented.

In addition, since the first support wall 51c has the groove portion 51c1, for example, when a protective sheet (not shown) for protecting the outer periphery of the polarizing plate 11 is placed between the first support member 51 and the polarizing plate 11, the lower end of the protective sheet can be inserted into the groove portion 51c1 for positioning. Similarly, the lower end of the protective sheet can be inserted into the groove portion 51c1 for positioning in the groove portion 52c1 of the second support wall 52c.

The material of the first support member 51 and the second support member 52 is not particularly limited, but it is preferable that they are made of resin, since this has excellent durability and is easy to reduce the weight.
(Polarizer)
The rectangular polarizing plate 11 is rectangular, but may be square. The rectangular shape may have chamfered corners. The polarizing plate 11 packed in the package 10 may be used, for example, as an optical component constituting a liquid crystal display device, without any particular limitations.

The thickness of each polarizing plate is not particularly limited, but is in the range of 50 μm to 500 μm.
<Packing procedure for polarizing plates using packaging material>
1 and 3, when packaging polarizing plate 11 in package 10, first, polarizing plate 11 is supported by first support member 51 and second support member 52. Specifically, a first support wall 51c of first support member 51 supports polarizing plate 11 at one corner side of polarizing plate 11. Then, first side 11a which is a short side and second side 11b which is a long side of polarizing plate 11 are abutted against first partition wall 51a and second partition wall 51b of first support member 51.

Similarly, the second support wall 52c of the second support member 52 supports the polarizing plate 11 at another corner diagonally opposite the above-mentioned corner of the polarizing plate 11. Then, the third side 11c, which is the short side, and the fourth side 11d, which is the long side, of the polarizing plate 11 are abutted against the third partition wall 52a and the fourth partition wall 52b of the second support member 52. The polarizing plate 11 supported by the first support member 51 and the second support member 52 is placed on the bottom wall portion 21 of the container 20.

As shown in FIG. 2, next, a pair of first cushioning materials 31 and a pair of second cushioning materials 32 are placed on the inner circumference of the side wall portion 22. The pair of first cushioning materials 31 come into contact with the second partition wall 51b of the first support member 51 and the fourth partition wall 52b of the second support member 52. The pair of second cushioning materials 32 come into contact with the first partition wall 51a of the first support member 51 and the third partition wall 52a of the second support member 52.

Next, a plate-shaped cushioning material 40 is placed on the surface of the polarizing plate 11 opposite the bottom wall portion 21. The polarizing plate 11 can then be packaged by attaching a lid 23 to the container 20. The above steps may be carried out in any order.

Container 20 and lid 23 may be secured in place relative to one another using tape, if desired.
When the lid 23 is attached to the container 20, the overall shape of the package 10 becomes a substantially rectangular parallelepiped shape. Therefore, as shown in FIG. 1, the package 10 can be placed on a table with the four sides of the rectangular polarizing plate 11 approximately parallel to the horizontal direction (also referred to as horizontal orientation), or the package 10 can be placed on a table with the four sides of the rectangular polarizing plate 11 approximately perpendicular to the horizontal direction (also referred to as vertical orientation). That is, the package 10 can be placed with the side wall 22 of the container 20 and the peripheral wall 25 of the lid 23 approximately parallel to the horizontal direction. As a result, when the package 10 is transported, the polarizing plate 11 can be transported not only in the horizontal direction but also in the vertical direction.

<Action and Effects>
The operation and effects of this embodiment will be described.
1, when removing the polarizing plate 11 from the package 10 in which the polarizing plate 11 is packed, the lid 23 is first removed from the container 20. Next, the plate-shaped cushioning material 40 arranged on the polarizing plate 11 is removed.

As shown in FIG. 8, the pair of first cushioning materials 31 and the pair of second cushioning materials 32 are further removed. Then, the space S1 in which the first cushioning materials 31 and the second cushioning materials 32 were inserted is exposed between the inner circumference of the side wall portion 22 of the container 20 and the first support member 51 and the second support member 52.

Also, a space S2 is originally formed between the polarizing plate 11 and the bottom wall portion 21. This space S2 is formed by the polarizing plate 11 being supported by the first support wall 51c of the first support member 51 and the second support wall 52c of the second support member 52.

The length of the second partition wall 51b of the first support member 51 and the fourth partition wall 52b of the second support member 52 are shorter than the lengths of the second side 11b and the fourth side 11d of the polarizing plate 11, so that the space S2 is connected to the space S1 in a wider area on the long side of the polarizing plate 11.

Therefore, the polarizing plate 11 can be removed by inserting a hand from the space S1 side into the bottom wall portion 21 side of the polarizing plate 11 where the space S2 is formed. The space S2 functions as an insertion portion for inserting a hand into the bottom wall portion 21 side of the polarizing plate 11.

In addition, it becomes possible to insert hands into the bottom wall 21 side of the polarizing plate 11 from both sides of a pair of opposing long sides (second side 11b and fourth side 11d) of the polarizing plate 11. This makes it possible to suppress deflection of the rectangular polarizing plate 11 and remove the polarizing plate 11 in a more stable state than when inserting hands into the bottom wall 21 side of the polarizing plate 11 from both sides of a pair of opposing short sides (first side 11a and third side 11c) of the rectangular polarizing plate 11. Therefore, the work efficiency when removing the polarizing plate 11 from the container 20 can be improved. In addition, if the thickness of the plate member 53 is 1 cm or more and 5 cm or less, it is easy to insert hands into the insertion part.

The above "hand" refers to the fingers and palm of the worker. The task of removing the polarizing plate 11 from the container 20 can also be performed using a machine such as a robot, and devices such as a robot hand are also included in the above "hand." In other words, the above "hand" is not limited to a human hand.

The above-mentioned "bottom wall portion 21 side of polarizing plate 11" can be rephrased as "the back side of polarizing plate 11".
Furthermore, when the size of the polarizing plate 11 to be packaged using the package 10 is changed, the polarizing plate 11 can be supported by the first support member 51 and the second support member 52, and then the sizes of the first buffer material 31 and the second buffer material 32 can be changed to match the size of the polarizing plate 11. When the first buffer material 31 and the second buffer material 32 are made of a material that is easily elastically deformed, the polarizing plate 11 can be packaged using the same first buffer material 31 and second buffer material 32 even if the size of the polarizing plate 11 is changed.

In this way, even if the size of the polarizing plate 11 is changed, the polarizing plate 11 can be supported and packaged in the same way using the same first support member 51 and second support member 52. Since the task of adjusting the position of the slider 64 according to the size of the polarizing plate, as in the carrier box 60 of the prior art, can be omitted, the polarizing plate 11 can be packaged efficiently.

<Example of change>
This embodiment can be modified as follows: This embodiment and the following modifications can be combined with each other to the extent that there is no technical contradiction.

- In this embodiment, the polarizing plate 11 is configured so that a hand can be inserted into the rear side of the polarizing plate 11 from both sides of the pair of long sides, but the present invention is not limited to this aspect. The polarizing plate 11 may be configured so that a hand can be inserted into the rear side of the polarizing plate 11 from both sides of the pair of short sides. In addition to being configured so that a hand can be inserted into the rear side of the polarizing plate 11 from both sides of the pair of long sides of the polarizing plate 11, the polarizing plate 11 may be configured so that a hand can be inserted into the rear side of the polarizing plate 11 from both sides of the pair of short sides. Also, the polarizing plate 11 may be configured so that a hand can be inserted into the rear side of the polarizing plate 11 from only one of the pair of long sides or only one of the pair of short sides.

- In this embodiment, the length of the first partition wall 51a is configured to be shorter than the length of the first side 11a of the polarizing plate 11, but the length of the first partition wall 51a may be the same as the length of the first side 11a. Similarly, the length of the second partition wall 51b may be the same as the length of the second side 11b, the length of the third partition wall 52a may be the same as the length of the third side 11c, and the length of the fourth partition wall 52b may be the same as the length of the fourth side 11d.

- The length of the first partition wall 51a may be the same as the length of the third partition wall 52a or may be different. Also, the length of the second partition wall 51b may be the same as the length of the fourth partition wall 52b or may be different.

- In this embodiment, the notch 54a in the first connection portion 54 of the first support member 51 and the notch 55a in the second connection portion 55 of the second support member 52 may be omitted. In other words, the first connection portion 54 and the second connection portion 55 may abut against the corners of the polarizing plate 11.

- In this embodiment, the first support member 51 and the second support member 52 have the same shape, but this is not limited to this. The first support member 51 and the second support member 52 may have different shapes.

- In this embodiment, the plate member 53 may be omitted. When the first support member 51 and the second support member do not have the plate member 53 arranged thereon, it is preferable that the thickness of the first support wall 51c and the second support wall 52c is 1 cm or more and 5 cm or less. This makes it easier to insert a hand into the insertion portion even when the plate member 53 is not arranged. Here, the thickness of the first support wall 51c and the second support wall 52c refers to the thickness in the stacking direction of the polarizing plate 11.

In the present embodiment, the plate-shaped cushioning material 40 may be omitted.
In the present embodiment, the through hole 51d may be omitted, and similarly, the through hole 52d may be omitted.

- In this embodiment, the bottom wall portion 21 of the container 20 is rectangular, but it may also be square.
