Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an optical film storage box and an optical film receiving tray,

The present invention improves the stacking structure of a storage box, efficiently utilizes a stacking space, and provides a folding pedestal on a carrier carrying the storage box to enhance the work efficiency of a worker.

The optical film is manufactured through a manufacturing process such as tensile, extrusion, surface coating, lamination, cutting and the like in order to impart functionality to a resin film. These optical films are usually manufactured through various processes such as superposing a special film. When the work is completed in the unit process, the optical film is transferred to the next process in a storage box for movement between the processes.

Conventionally, a method of loading and transporting an optical film by using a coverless lid has been used. However, since a packaging process for eliminating the influence of foreign objects or moisture is added, a lot of work and manpower are required, And scratches are generated or broken.

For the purpose of preventing damage to the film during the handling process, a case for packaging an optical film with a cover for opening and closing the loading space has been developed. For example, Korean Patent No. 10-0867966 (entitled " Quot; case ") and Korean Patent No. 10-0944810 (" polarizing film storage case ").

In the prior art, although a cover is individually provided on the storage case to prevent the air from being cut off and the film to be damaged, the manufacturing cost is increased due to the complicated structure. In addition, it is troublesome to put a load on a storage case and to open and close a cover every time it is taken out, which is inconvenient for a film pulling operation when a large number of films are stacked on a carrier truck.

In consideration of this problem, Korean Patent Registration No. 10-1169324 filed by the applicant of the present invention discloses a technique of blocking the inflow of outside air by applying a double-sealing structure to the rim where the storage chambers stacked without layers are interlocked with each other There is one.

The prior art has means for fixing the film stacked inside the storage case. When the fixing means is designed to fix a single type of film, a separate storage case is made to stack films of different sizes shall. If the position of the fixing means for supporting the side of the loaded film can be moved, it can be applied to a wide or narrow film, which may have an advantage of increasing the film to be loaded.

However, in the conventional art, when a narrow film is loaded on a single storage case designed to accommodate a wide film, unnecessary space is not required in which the film is not located in the entire space. Therefore, There is a drawback that the space can not be efficiently utilized.

Accordingly, in order to solve the above-described prior art and other problems, it is possible to change the loading position of the film according to the size of the object to be loaded, to easily pull out and fix the film to be loaded on the box, It is required to be able to easily handle the clearing of the carrying case.

Korean Patent Registration No. 10-0867966 (November 12, 2008) Korean Patent Registration No. 10-0944810 (Feb. 26, 2010) Korean Patent Registration No. 10-1169324 (Aug. 13, 2012)
