  By the way, in the prior art disclosed in Patent Documents 1 to 4, the storage tray and storage case for storing and transporting ultra-precision metal parts and the like are not sufficiently equipped with necessary functions. For example, the tray disclosed in Patent Document 1 prevents positional deviation in the vertical direction and in the horizontal direction by pushing and holding the storage component in the gap of the recess of the tray. However, in the case of ultraprecision metal parts, there is a concern that plastic deformation may occur due to external stress, and it is not possible to press the storage parts into the gaps in the recess of the tray. In addition, since the trays of Patent Document 1 are premised that a plurality of trays are stacked and stored, they are adopted when used individually for storage and transportation of individual parts for each one storage tray. Can not.

  Moreover, the tray disclosed by patent document 2 laminates | stacks a some tray, and is pinching storage components between two upper and lower trays. However, in this case, when the upper tray serving as the lid is removed, the support of the storage part becomes unstable. In addition, since the storage parts are in direct contact with the structural members of the upper and lower two trays, there is a possibility that damage may occur due to friction with the structural members, and it is not suitable as a storage tray for ultraprecision metal parts.

  Further, in the tray disclosed in Patent Document 3, the storage components can be placed in the recessed portion of the tray to prevent positional deviation in the horizontal direction, and dust can be prevented from entering by stacking a plurality of trays. It is. However, in this case, since the storage components are merely placed in the recess of the tray, it is not possible to prevent the occurrence of displacement due to vertical vibration such as transportation by a vehicle and generation of impact force due to vibration. In addition, since the storage parts are in direct contact with the structural members of the tray, there is a possibility that damage may occur due to friction with the structural members, which is not suitable as a storage tray for ultra-precision metal parts.

Further, the storage structure of the pellicle disclosed in Patent Document 4 is a tray for the pellicle used to prevent foreign substances from adhering to a photomask or reticle used in a lithography process for manufacturing an LSI or the like. It is stored in the case which consists of and a lid.
The feature of the invention according to Patent Document 4 is that when the pellicle is restrained by bringing the tray and the lid into contact with the protective film provided on the frame of the pellicle and the pellicle is transported in this state, vibration during transportation or According to the invention, it is possible to prevent the pellicle from being rubbed and damaged by impact, and dust generated by strong rubbing and adhering to the pellicle. However, because the Pectel film is in a state of being bonded to a rigid frame, it is possible to make a non-contact structure with a tray or a lid, but in the case of ultraprecision metal parts, it may be bonded to a frame Since it can not do, the structure of patent document 4 can not be adopted.

  On the other hand, storage trays for storing parts that have been subjected to special surface treatment that are easily peeled off, parts that need to avoid adhesion of foreign matter to the surface during storage and transportation, etc. It is desirable to have a superior protection function to cover and protect the components and to prevent local stressing of the contained parts. In addition, it is desirable that the storage tray be a storage case with a lid so that it can be used independently for storage and transportation of individual parts independently for each storage tray in common in the processing and assembly process of parts.

FIG. 4 shows a cross-sectional view of the storage case 1 in which the plate-like component 2 is stored. FIG. 4 is a cross-sectional view taken along a straight line (line AA in FIG. 3) which intersects the fitting concave portion 120 and the fitting convex portion 220 of the storage case 1.
The operation of the storage case 1 for storing the plate-like component 2 will be described based on FIG. 4.

  The storage case 1 stores the plate-like component 2 in the storage recess 110 of the tray body 100 and overlaps (closes) the lid 200 from the upper side, so that the plate-like component 2 supports the first support member 160 and the second support. It is sandwiched between the members 260. Since the gap portion 103 is provided around the first support member 160 and the gap portion 203 is provided around the second support member 260, the first support member 160 and the second support member 260 are provided. Can support the inner side of the peripheral portion 2 c so as to avoid the peripheral portion 2 c of the plate-like part 2. Another member is assembled to the peripheral portion 2 c of the plate-like part 2, and the thickness becomes larger with respect to the main surface portion 2 a. By arranging the first support member 160 and the second support member 260 so as to avoid the peripheral portion 2c, the plate-like component 2 can be supported in a state where the peripheral portion 2c is floated.

  The first support member 160 and the second support member 260 are both made of a cushioning material. By using the first support member 160 and the second support member 260 as cushions, the plate-like component 2 is held in the posture stored in the storage case 1 and vibration is applied by transportation by a vehicle or the like. Also, it is difficult for the impact to be transmitted to the plate-like part 2, and it is difficult for displacement due to vibration and damage due to vibration friction to occur.

In the case where the first support member 160 and the second support member 260 are used as a cushion material, the first support member 160 and the second support member are stored with the plate-like component 2 stored and the storage case 1 closed. It is preferable to support the plate-like part 2 in a state in which 260 is compressed. Also, even if the first support member 160 and the second support member 260 are in the most compressed state, a sufficient gap is formed between the peripheral portion 2c and the tray body 100 and the lid 200. It is preferable to set it as such.
The thickness of the first support member 160 and the thickness of the second support member 260 may not necessarily be the same. The thickness of one of the support members is increased according to the thickness of the peripheral component 2d to be laminated to the peripheral portion 2c of the plate-like component 2 and the laminating direction, and the peripheral component 2d has the structure of the tray body 100 and the lid 200 It is preferable that the member be configured not to be in contact with it.

  Since the first support member 160 and the second support member 260 are cushioning materials, the first support member 160 and the second support member 260 are pressed against the plate-like part 2 and the plate-like part 2 is obtained. It deforms along the surface shape. As a result, the first support member 160 and the second support member 260 and the plate-like part 2 become difficult to slip, and the plate-like part 2 in the sandwiched state is unlikely to be misaligned even if it receives vibration or the like. Therefore, even when receiving vibration in the vertical direction, such as during transportation by a vehicle, the plate-like component 2 is prevented from colliding with the wall portion 112 of the storage recess 110, and the plate-like component 2 is externally stressed. It can protect from plastic deformation.

As shown in FIG. 4, the plate-like component 2 stored in the storage case 1 has the first support member 160 and the vicinity of the central portion thereof (more specifically, the special plating 2 b shown in FIG. 1). It is sandwiched and supported by the second support member 260. Accordingly, the peripheral portion 2 c of the plate-like part 2 floats in the air without contacting the tray body 100 and the lid 200. When the peripheral portion 2c is a delicate portion that may be damaged by contacting the tray body 100 and the lid 200, the peripheral portion 2c can be prevented from being damaged.
In addition, the storage case 1 is supported in a supported state with a predetermined gap in the thickness direction with the tray body 100 and the lid 200 in which the peripheral portions 2 c of the plate-like parts 2 overlap vertically. Therefore, the storage case 1 can be commonly used even for a semi-assembled product in which another component (peripheral component 2 d) is stacked on the peripheral portion 2 c of the plate-like component 2.

  Further, the storage case 1 of the present embodiment has a column body 161 provided in the storage recess 110 of the tray body 100 corresponding to the position of the through hole 2 e of the plate-like component 2. The column body 161 is formed smaller in diameter than the through hole 2 e. Thereby, by storing the plate-like component 2 in the storage recess 110 of the tray body 100, the pillar body 161 enters the through hole 2e, and the plate-like component 2 is stored in the storage recess 110. A part of the outer periphery of the column body 161 can be in contact with the inner periphery of the through hole 2 e to suppress movement of the plate-like component 2 in the surface direction.

  The thickness of the column body 161 is preferably larger than the thickness of the first support member 160. Thus, by mounting the plate-like component 2 on the first support member 160, the column body 161 can be inserted into the through hole 2 e of the plate-like component 2. Therefore, even in the state where the storage case 1 is opened, it is possible to suppress the movement of the plate-like component 2 mounted on the tray body 100 in the surface direction.

It is preferable to use a cushion material for the column body 161, and the same material as the first support member 160 and the second support member 260 can be used.
When a cushion material is used as the column body 161, when the part of the outer periphery of the column body 161 abuts on the inner periphery of the through hole 2 e of the plate-like component 2, the plate-like component 2 is not damaged.
