Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(Embodiment 1)
The packaging set 1 according to the first embodiment (see FIG. 8) includes a plurality of storage trays 3 having a rectangular shape in plan view, as shown in FIGS. The storage tray 3 is made of resin, and is formed by vacuum forming or the like using a thermoplastic resin such as polyethylene, polypropylene, and polystyrene as a raw material. Further, the object stored in the storage tray 3 is a plate-shaped storage object, and in this example, the FPC-equipped liquid crystal module 5 in which a flexible printed circuit board (FPC) 5b is mounted on a rectangular liquid crystal panel 5a is exemplified. The type is not limited as long as it is a plate-like object.

The storage tray 3 has a plurality of storage recesses 7 in which the liquid crystal module 5 with FPC is stored. Specifically, ten storage recesses 7 are arranged in two rows of 5 in the longitudinal direction, but the number of storage recesses 7 is not limited to this, and is appropriately determined according to the size of the plate-shaped storage object. For example, if the plate-shaped storage item is large, the storage recess 7 may be one.

The storage recess 7 includes a rectangular panel storage recess 9 that stores the liquid crystal panel 5a, and an FPC storage recess 11 that is continuous with the panel storage 9 and stores the flexible printed circuit board 5b. A first support portion 13a is integrally formed in a rectangular ring shape on the outer periphery of the bottom surface 13 of the panel storage recess 9, and the liquid crystal panel 5a is supported by the first support portion 13a from below on the outer peripheral edge thereof. 3 is installed.

A step-down recess 15 is formed outside the first support portion 13a of the panel storage recess 9 so as to communicate with the adjacent panel storage recess 9, and below the first support portion 13a of the step-down recess 15 The pressing portion 15a is provided adjacent to the inclined portion, and the pressing portion 15a is positioned above the first support portion 13a of the lower storage tray 3 in a state where the storage tray 3 is vertically stacked. The outer peripheral edge of the liquid crystal panel 5a of the liquid crystal module 5 with FPC mounted on the lower storage tray 3 is pressed from above.

The second support portion 17a is provided on the outer side of the pressing portion 15a of the panel storage recess 9 at both ends of the five panel storage recesses 9 in the row, that is, on the side surface 17 of the panel storage recess 9 above the stepped recess 15. The upper storage tray 3 is supported by the second support portion 17a from below with the storage tray 3 being vertically stacked and projecting integrally in the direction.

The storage tray 3 is used by overlapping a plurality of sheets. In a state where these storage trays 3 are vertically stacked, one protective sheet 19 is disposed in each of the storage recesses 7 of the storage tray 3 except for the uppermost portion. The FPC-equipped liquid crystal module 5 is stored in a stacked state with the protective sheet 19 sandwiched in the storage recess 7 of the storage tray 3 excluding the uppermost portion, with the same orientation. In this example, the types of the FPC-equipped liquid crystal modules 5 that are arranged are different between the upper and lower sides of the protective sheet 19 (see FIG. 1). The protective sheet 19 is formed of a material such as a flexible and buffering resin so that a cover portion 19a covering the liquid crystal module with FPC 5 accommodated in each of the storage recesses 7 corresponds to each of the storage recesses 7. A plurality of parts are connected via a connecting part 19b.

In this way, the liquid crystal module 5 with FPC is stored in a stacked state vertically with the protective sheet 19 sandwiched between the storage recesses 7 of the storage tray 3 except for the uppermost portion, so two FPCs are attached to one storage recess 7. The liquid crystal module 5 can be accommodated. Therefore, without increasing the size of the storage tray 3 (without being bulky), the number of the FPC-equipped liquid crystal modules 5 per storage tray can be doubled and efficiently conveyed.

In addition, while the storage tray 3 is vertically stacked, the pressing portion 15a of the upper storage tray 3 presses the outer peripheral edge of the liquid crystal panel 5a of the liquid crystal module 5 with FPC mounted on the lower storage tray 3 from above. Since the tray 3 is supported from below by the second support portion 17a of the lower storage tray 3, the pressing force of the pressing portion 15a can be prevented from acting on the outer peripheral edge of the liquid crystal panel 5a more than necessary. Further, since the pressing portion 15a of the upper storage tray 3 is positioned above the first support portion 13a of the lower storage tray 3, the shearing force acting on the liquid crystal panel 5a can be reduced. As a result, the FPC-equipped liquid crystal module 5 (liquid crystal panel 5a) can be protected from external force to prevent damage.

The side surface 17 of the storage recess 7 is formed with an inclined surface portion 17b in which the opening of the storage recess 7 gradually expands from the bottom surface 13 to the opening end, for example, at an inclination angle of 5 to 7 degrees. Further, at the four corners of the side surface 17 of the storage recess 7, vertical surface portions 17c extending from the middle in the up-down direction to the opening end so as to correspond to the shape of the liquid crystal panel 5a and perpendicular to the bottom surface 13 are formed. An inclined surface portion 17d having an inclination angle α of, for example, 2 degrees to 4 degrees is formed from the surface portion 17c to the bottom surface 13.

Accordingly, the liquid crystal module 5 with FPC (liquid crystal panel 5a) can be stored in the storage recess 7 in a horizontal posture without being tilted while being guided by the inclined surface portion 17b, and the liquid crystal module 5 with upper FPC that overlaps vertically (liquid crystal panel). It is possible to stabilize the stacked state of the FPC-equipped liquid crystal module 5 (liquid crystal panel 5a) by regulating the horizontal movement (backlash) of 5a) by the vertical surface portion 17c.

The outer periphery of the storage tray 3 includes a horizontal wall 21 that surrounds the storage recess 7, a vertical wall 23 that extends downwardly from the outer peripheral edge of the horizontal wall 21, and a lower end edge of the vertical wall 23. A flange 25 projecting outward is integrally formed. Further, rounded portions 27 are formed at the boundary between the horizontal wall 21 and the vertical wall 23 and at the boundary between the flange 25 and the vertical wall 23, respectively.

In this manner, the rounded portion 27 is formed at the edge of the outer peripheral portion of the storage tray 3, so that stress is not concentrated on the portion, and the storage tray 3 can sufficiently resist an impact during conveyance. Breakage can be prevented.

The horizontal wall 21 is provided with a plurality of positioning cylinder portions 31 each having a concave portion 29 that opens upward. The positioning cylinder portions 31 protrude downward with a predetermined interval. The inner surface of the concave portion 29 of each positioning cylinder portion 31 is open on the bottom side. A stepped portion 29a is formed so as to open larger, a circular upper recessed portion 29b is formed on the opening side with the stepped portion 29a as a boundary, and a lower recessed portion 29c having a cross-shaped cross section is formed on the bottom side. Then, in a state where the storage tray 3 is vertically stacked, the positioning cylinder portion 31 of the upper storage tray 3 is inserted from above into the concave portion 29 of the positioning cylinder portion 31 of the lower storage tray 3 so that the lower storage tray 3 While being in contact with the stepped portion 29a, the positioning cylinder portion 31 of the lowermost storage tray 3 is in contact with the placement surface. The lower recess 29c is not limited to a cross-shaped cross section, and may be a circle having a smaller diameter than the upper recess 29b, or may be a polygon, an ellipse, or other shapes.

Therefore, the upper storage tray 3 is not displaced in the horizontal direction and the vertical direction, and the upper storage tray 3 can be stably stacked on the lower storage tray 3, and the positioning cylinder portion 31 of the lowermost storage tray 3 is provided. By contacting the placement surface, the storage tray 3 can be stably stacked in multiple stages.

A similar positioning cylinder portion 31 is also formed between two rows of the storage recesses 7 rows. Further, the horizontal wall 21 is formed so that the upper surface reinforcing concave portion 21a is positioned between the adjacent positioning cylinder portions 31, and the side wall reinforcing concave portion 23a is also spaced apart from the vertical wall 23 by a predetermined distance. A plurality of the upper surface-reinforcing recesses 21 a and the side-surface reinforcing recesses 23 a ensure the rigidity of the outer peripheral portion of the storage tray 3.

As shown in FIG. 5, the storage tray 3 is configured such that the liquid crystal module 5 with FPC is stored in the storage recess 7 in two upper and lower layers with a protective sheet 19 made of, for example, an antistatic treatment interposed therebetween. Further, as shown in FIG. 6, they are wrapped in a protective bag 33 and sealed with a crepe tape 35 to form a set of storage tray assemblies 37.

Therefore, it is possible to prevent foreign matter and dust from adhering to the storage tray 3 and to stabilize the overlapping state of the storage tray 3.

Further, the storage tray 3 can be easily managed by collecting a plurality of storage trays 3 into a single storage tray assembly 37.

As shown in FIG. 7, the storage tray assembly 37 configured in this way is stacked two sets up and down across the partition sheet 39, and after being wrapped with the cover sheet 41 as shown in FIG. 8, It is inserted from both sides and stored in a storage case 43 that is open at both ends.

Therefore, by storing the storage tray assembly 37 in the storage case 43, it is possible to reliably prevent the storage tray 3 from being separated, and to store a plurality of sets of storage tray assemblies 37 in one storage case 43. As a result, the management of the storage tray 3 is further improved.

A plurality of storage cases 43 storing the storage tray assembly 37 are stored in a packaging box 45, packed, and transported to a destination.

Therefore, a plurality of storage trays 3 can be taken in and out in units of storage cases 43, and the storage trays 3 can be handled easily.

The partition sheet 39, the cover sheet 41, the storage case 43, and the storage case 43 may be made of, for example, paper cardboard or resin cardboard regardless of the material.

That is, in the second embodiment, two protective sheets 19 are used in the storage tray 3 and three liquid crystal modules 5 with the same type of FPC are vertically moved with respect to one storage recess 7 with the protective sheet 19 interposed therebetween. Stored in a stacked state. In the first embodiment, the thickness of the FPC-equipped liquid crystal module 5 is thicker than that of the second embodiment assuming that a backlight is mounted (see FIGS. 2 and 10).

In addition, the upper and lower three-layer liquid crystal modules 5 with FPCs are stored in the storage recesses 7 while being turned 180 degrees from each other.

Thereby, the load distribution of the storage tray 3 can be eliminated and the liquid crystal module 5 with FPC can be stored in a well-balanced manner, and interference between the convex portions of the liquid crystal module 5 with FPC can be avoided.

Further, at one of the four corners of the protective sheet 19, a protruding portion 19c that recognizes the direction of the protective sheet 19 is integrally projected sideways, while the horizontal wall 21 on the outer periphery of the storage tray 3 is provided on the horizontal wall 21. An insertion recess 21b for inserting the protrusion 19c is formed.

Therefore, by inserting the protruding portion 19c of the protective sheet 19 into the insertion recess 21b of the storage tray 3, the protective sheet 19 can be disposed in the storage tray 3 in a normal orientation.

In addition, a T-shaped slit 19d is formed in the connecting portion 19b for connecting the cover portion 19a of the protective sheet 19 so as to divide the adjacent cover portion 19a. The slit 19d is not limited to the T shape, and may be an H shape, a U shape, or other shapes.

Therefore, when the liquid crystal module 5 with FPC on the protective sheet 19 is taken out, even if the connecting portion 19b on the side of the liquid crystal module 5 with FPC is pushed downward with a finger, the pressing force is blocked by the slit 19d and the adjacent cover Regardless of the portion 19a, the FPC-equipped liquid crystal module 5 on the cover portion 19a can be prevented from being lifted and displaced, and subsequent conveyance can be prevented from being hindered.

In the second embodiment, two ridges 13 b are arranged in parallel on the bottom surface 13 of the storage recess 7 to reinforce the bottom surface 13.
