  As described above, packaging boxes belonging to the field of film packaging that uses a film space holding buffer system are already known, but in the past, in many cases, when packing small precision devices such as HDDs, individual packaging with a bubble sheet is required. In order to protect the HDD from transportation impact, the packaging work is performed again using the cushioning material for filling. Alternatively, a foamed polyethylene molded product pad is used as an HDD cushioning material. Therefore, Table 1 “Packaging problems and points of development” below clarifies the development points by clarifying the conventional packaging issues.

  In packaging development, the following three items in Table 2 “Packaging Development Procedure” were examined and specific numerical values were determined.

The returnable box for small precision equipment according to the present invention was developed as an optimum returnable box by repeating a plurality of types of HDDs as actual packed objects as a small precision equipment. In fact, the following HDDs were prepared for demonstration experiments.
Packaged item 1: width 101 x length 147 x thickness 26 (mm)
Packaged item 2: width 110 × length 167 × thickness 26 (mm)
Package 3: width 110 x length 179 x thickness 26 (mm)
Packaged item 4: width 140 x length 188 x thickness 31 (mm)
Package 5: width 112 x length 227 x thickness 26 (mm)

  As described above, the dimensions of the objects to be packed were 140 × 188 × 31 mm in thickness at the maximum value, 101 × vertical 147 × 26 mm in thickness at the minimum value, and there was a difference of about 80 mm in the vertical dimension. The weight was not so different from 0.6 to 0.8 kg.

  In the examination and selection of the basic structure of the shock absorber, the storage and use amount of HDDs with different shapes are shown in Table 3 “Characteristic comparison of various shock absorbers” for the five basic shock absorber structures currently on the market. In consideration of the cost, the buffer method of the film frame was examined.

  In the examination and selection of the material of the shock absorber, the materials used for the shock absorber and the container are three types: corrugated cardboard, polyurethane film, and double-sided adhesive tape as shown in Table 4 “Materials of various packaging materials” below.・ We decided to select the most suitable material through testing.

  As shown in FIG. 7A, the buffer body has a width of 30 mm as the film frame, and the maximum HDD dimension (vertical maximum dimension 227 mm, horizontal maximum dimension 140 mm) based on the HDD thickness and film elongation. On the other hand, the length of the film was increased by 20 mm around the periphery, and the buffer distance was 50 mm in both length and width (frame width 30 mm + film length around the packaged body 20 mm). As for the thickness, the frame width was 48.5 mm with respect to 1/2 of the HDD thickness (31 mm), and the buffer distance was 33 mm. FIG. 7B schematically shows the cross-sectional shape of the film frame, and FIG. 7C shows a state in which the upper and lower film frames are overlapped.

  First, as a result of prototyping an L-shaped film frame and performing a drop test, the HDD completely moved in the dropping direction as shown in FIG. 8, and the frame portion of the film frame was bent and deformed. A big problem emerged that caused a shock that exceeded expectations. Thus, it has been found that a good effect cannot always be obtained simply by constructing a transport box of the film space holding buffer system. It was found that the cause is that the pressure of the film sandwiching the HDD is weak, the frame is broken by the impact (the part in the circle indicated by the dotted line in the figure), and the deflection of the frame increases. . For this reason, improvements were made to the structural design of the frame, and the selection of the film thickness and the method of bonding to the frame became an issue.

  Therefore, in order to prevent the movement of the HDD in the buffer body due to a drop impact, the structure of the frame of the buffer body has been changed from an L-shaped section to a U-shaped section (FIG. 6) according to the present invention. This was improved to a film frame that was added to four central portions on the four sides of the frame. As a result of a comparative examination by a drop test while changing the film thickness, the material of the cardboard, and the width of the double-sided adhesive tape to the frame structure of the present invention thus improved, the following Table 5 “Packaging material for an improved film frame” The packaging materials shown in Fig. 1 were selected.

  With this improvement, the present invention has solved the problem that the HDD moves greatly when dropped. In addition, the strength of the frame has increased, and corrugated cardboard can use materials that are one rank lower than the K6 type, leading to cost reduction.

The package of the present invention was constituted by four types of HDDs with trays, and a drop test was performed. The result is as shown in FIG. 9 and within the allowable acceleration of 60G. The conditions of the drop test and the vibration test that were actually performed are as follows, and all the HDD operation tests were normal.
(1) The drop test is JIS Z 0202 level 3, height 40 cm, 10-point drop of 6 corners on one side and 3 faces. (2) The vibration test is JIS Z 0232 method A-1, sweeping double time 20 minutes, 0.75G , 5-100Hz

  Hereinafter, embodiments of the returnable box for small precision equipment of the present invention will be described in detail with reference to the drawings.

The returnable box 100 is one in which upper and lower film frames 30 and 50 are accommodated in a cardboard container 10. In the present embodiment, the upper and lower film frames 30 and 50 are structurally the same. However, it is also possible to change the dimensions of the upper and lower film frame bodies 30 and 50 depending on the shape of an object to be packed. For example, one of the dimensions in the thickness direction is changed due to the presence of a protrusion on one of the tops and bottoms of the object to be packed.

  Although not described in detail here, in order to reduce the pressure-sensitive adhesive tape of the corrugated cardboard container 10, the structure is such that one-touch assembly can be performed by inserting only one bottom of the corrugated cardboard container 10.
