Description

[Detailed Description of the Invention] A. Field of Industrial Application The present invention relates to a tray for transporting ring-shaped articles (for example, magnetic tape wound bodies called pancakes).

B. Prior art The magnetic tape loaded into a tape cassette etc.
During its manufacturing process, it is wound around a core material at a predetermined tension and stored and transported as a pancake of a certain diameter.

However, conventional transport trays for storing such pancakes have a structure in which a foamed polyethylene cushion material is simply pasted in a ring shape on the inner surface of the foamed polystyrene tray body, and the pancakes are stored here. The material cost of the main body is high, and it is not suitable for transportation.

C. Purpose of the invention The purpose of the invention is to provide a tray that can reduce costs and weight, and has excellent transportability.

D. Structure of the invention That is, the invention comprises a tray main body, a through hole provided in a ring-shaped article storage area of the tray main body,
The present invention relates to a ring-shaped article transport tray having a cushion material attached to the ring-shaped article storage area of the tray body while covering the through hole.

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

1 to 3 show a tray 1 for transporting pancakes according to this embodiment.

This tray 1 consists of a tray body 2 made of expanded polystyrene having a substantially regular octagonal shape, and a circular through hole provided by punching or the like at a positional relationship of approximately 90 degrees in the circumferential direction in a pancake storage area 3 of the tray body. It has holes 4 and ring-shaped cushioning materials 5 and 6 made of foamed polyethylene which are respectively adhered to both sides of the tray body so as to cover these through-holes 4. Further, a circular projection 7 is provided at the center of the tray body 2, and a cushion material 10 (a magnetic tape 8 wound around a core material 9) 10 is placed around this projection as shown in FIG. 5
accommodated above.

When transporting or storing, a plurality of trays 1 are stacked vertically as shown in FIG. 3 (however, only two trays are shown in the drawing).
However, the pancake 3 is well sandwiched between the cushion materials 6-5 of the upper and lower trays.

According to this embodiment, as described above, since the four through holes 4 are formed in the expensive tray body 2, the amount of raw materials can be reduced to reduce costs, and the weight can also be reduced. become.
Therefore, the required performance as a transport tray can be improved, and the effects of weight reduction and cost reduction can be achieved all at once.

Further, as can be understood from FIG. 3, the pancake 3 itself is well held by the upper and lower cushioning materials 6-5, and at the same time, the cushioning material is also provided in the area of the through hole 4, so that the cushioning property is improved. can be fully demonstrated. Therefore, it can withstand shock during transportation and has excellent transportability.

Although the through hole 4 has an important meaning as mentioned above, in FIG. 3, there is a distance R between the diameter R of the through hole 4 and the width W of the cushion material 5 (6) It is desirable that the relationship be ≦2/3W, and more preferably 1/4W≦R≦2/3W.

This range is desirable in order to obtain the above-mentioned effects. If R is too large, the cushioning properties will be affected or the strength will be undesirable, and if R is too small, it will not be possible to achieve the above-mentioned cost reduction and weight reduction. undesirable in some respects. Further, the number of through holes 4 is usually 3 to 8 in the circumferential direction, but the shape thereof may also be various other than the above-mentioned circle, such as an ellipse, a triangle, or a trapezoid.

FIG. 4 shows an example of an improved version of the above tray.

This tray 1 has diagonal (triangular cross-section) notches 11 formed on its four sides.
When stacking a large number of pieces as shown in Fig. 5 and hanging the cable ties 12 as shown in Fig. 6, the cable ties 1
2 will bite into the notch 11 (the fourth
(indicated by phantom lines in the figure). However, if the notches 11 are not provided and the band is tied, the band 12 will stick to the edge of the tray 1, but it is often seen that the band 12 becomes loose after the band is tied.

However, due to the presence of the notch 11, the notch 11
The band 12 is firmly attached and bound, and the structure is such that it is difficult to loosen.

Although the present invention has been illustrated above, the above-mentioned example can be modified in various ways based on the technical idea of the present invention.

For example, the shape, size, material of the tray body, etc.
Various manufacturing methods may be used. Notch 1 mentioned above
The position, number, and shape of 1 may be changed. Also,
Applicable articles may be ring-shaped articles other than pancakes.

F. Functions and Effects of the Invention As described above, in the present invention, since the tray body is provided with through holes, it is possible to realize cost reduction and weight reduction by saving materials. Moreover, since the through holes are covered with the cushion material, the cushioning properties are well exhibited and the transportability is sufficient.
