Packing box and package conformation article

Abstract

This invention provides a packing box, which has an upstanding end surface retentivity on the coiling body, and can prevent end surface dislocation. This packing box comprises a main body, a cover body installed in a free loading and unloading form on the main body; a coiling body formed by coiling the electronic machine parts forming film around the coiling core; the said main body comprises a base platform, on which face-to-face installs a pair of supporting units supporting the end part of the coiling core of the coiling body, a clamp device, which is installed in a free loading and unloading form on the said supporting units and holds the coiling core end between it and the said supporting units; at least one of the said supporting unit and said clamp device equips with a pressing device, which has a main body and a pressing part installed in a free moving and positioning form on the said main body, and between the supporting unit and the clamp device, the said pressing part presses the end surface of the electronic machine parts forming film of the said coiling body held by the said coiling core ends.

Description

technical field [0001] The present invention relates to a packaging box and a packaging structure, and more specifically, to a packaging box and a packaging box in which a wound body wound with a film for forming an electronic device part has excellent end face retention and can prevent end face misalignment due to shocks during transportation, etc. Packaging constructs. Background technique [0002] Conventionally, strip-shaped transfer films have been used to form components such as dielectric layers, electrodes, separators, phosphors, resistors, color filters, and black matrices in electronic devices such as plasma display panels. [0003] Such a transfer film is produced by, for example, forming a paste-like material layer on a support film made of plastic, and is usually wound on a core such as a cylinder to form a roll, and then stored in a packing box. Transportation is carried out (refer to, for example, Patent Documents 1 and 2). [0004] However, since the transf...

Problems solved by technology

[0004] However, since the transfer film for forming electronic equipment parts must protect the film thickness and shape of the paste layer, it cannot be wound too tightly on the core. Therefore, it is easy to cause misalignment of the end surface due to impact during transportation, etc. Fortunately, in the conventional packaging boxes including the above-mentioned Patent Documents 1 and 2, the status quo of preventing the misalignment of the end faces of the wound film cannot be ensured.

Such misalignment of the end face will cause damage to the paste layer, which will adversely affect the shape and performance of the final product such as a plasma display panel, so it becomes a problem
