Description

The present invention conveys polishing cloth, polishing cloth, holding pads, etc. used in polishing processing to flatten the surface of objects to be polished such as glass substrates for liquid crystal displays (LCD) and silicon wafers for semiconductor devices. The present invention relates to a packaging material for transportation.

Conventionally, polishing sheets, polishing cloths, polishing cloths, back pads and holding pads (hereinafter referred to as “pads”) used for precision polishing of glass substrates for liquid crystal displays (LCDs) are deformed by external force. Soft materials that are easy to receive are used, and in order to emphasize the flatness of the surface, about 10 sheets are stacked in a flat state and transported in a cardboard packaging.

However, with the increase in the size of the glass substrate for LCD, the size of the pad to be used has also increased, and the size exceeds the width of the loading platform such as a truck, making it difficult to carry it in an expanded state.
Therefore, it is rolled and transported. Even if it is made into a roll during transportation, it does not use curly folds, so do not use a roll core. For this reason, an invention of a transporting device is disclosed in which a flexible film is stretched between opposing partition walls of a container, and a roll-shaped pad is placed on a slack portion between the partition walls. (For example, see Patent Document 1)

JP 2009-137644 A

However, in the technique of Patent Document 1, since the roll-shaped pad is carried on the slack portion of the film passed between the partition walls, the roll-shaped pad rotates and jumps on the film due to vibration and shaking during transportation. The container was in contact with the cover or lid on the upper part of the container, and rubbed and scratched.
This invention makes it a subject to provide the packing material for conveyance which can be conveyed without producing a rubbing and a damage | wound in the roll-shaped pad which does not use a winding core in view of the said case.

That is, the present invention is characterized by the following in order to solve the above problems.

The first solving means for solving the above problems is a box body integrally provided with a pair of opposing outer flaps for closing at the opening edge, and both ends are mounted on the outer surface of the outer flap, A roll-shaped pad having a holding sheet having flexibility and flexibility, which is bonded and arranged across the opening of the box, and the holding sheet is accommodated from the opening of the box A packaging material for transporting a roll-shaped pad, which is encapsulated when the outer flap is closed, is suspended in a substantially covering shape, and the pad can be suspended at the inner center of the box, is a constituent requirement. is there.

The second solving means includes a cushioning material for preventing contact between the inner surface of the box and the holding sheet when closed, and the packaging for transporting the roll-shaped pad according to the first solving means The material is a constituent requirement.

The third solving means is the roll-shaped pad according to the first solving means or the second solving means, wherein a flap holding part for holding the closed outer flap is provided in the box. The packaging material for transportation is a constituent requirement.

The fourth solving means comprises the packaging material for transporting the roll-shaped pad according to the first to third solving means, further comprising an upper lid on the closed outer flap. It is a requirement.

According to the present invention, even if the box vibrates and shakes during transportation, the vibration and vibration are reduced or alleviated by the holding sheet having flexibility and flexibility, and the winding core is not used. The roll-shaped pad can be transported without contacting the inner surface of the packing material or the lid material.
In addition, when the outer flap is opened during packing, the holding sheet that suspends the roll-shaped pad inside opens greatly at the opening of the box so that the pad can be easily stored. Since the pad of the shape rises from the inside of the box to the opening, it can be easily taken out without damaging the pad.
