Description

Film packaging box for liquid crystal display products by corrugated paper by corrugated cardboard cross-lamination

The present invention relates to a film packaging box for liquid crystal display products made of corrugated cardboard cross-lamination, and more particularly, even when laminated in multiple layers in the process of storing and transporting the produced LCD (Liquid crystal display) film. It relates to a film packaging box for liquid crystal display products made of corrugated cardboard that allows the bottom and edge of the packaging box to not be easily deformed by weight, and to safely store LCD films.

In general, packaging refers to the technology and state of marketing appropriate materials or containers for goods in order to protect their value and condition in transporting and storing goods. There are three.

The basic functions of packaging as described above are protection, marketability, convenience, psychology and delivery of the packaging. In the past, the function and smallness of packaging had been placed on protection, and that was sufficient, but today, it has been expanded and focuses on the promotion function. It is difficult to call a product a product by itself, and it can be said that it is commercialized only when it is packaged.

Among these packaging, the LCD film, a film for liquid crystal display products, is an electrical device that converts and transmits various electrical information generated in various devices into visual information by using the change in transmittance of liquid crystal according to an applied voltage. It is a type of flat panel display widely used because it does not have self-luminescence and needs a halo, but it consumes little power and is convenient for portability. The packaging of LCD wide viewing angle compensation film, luminance improvement film, and liquid crystal film is a high-precision part that can be damaged even by a small impact, and has been packed with impact-resistant material to prevent impact inside the packaging box. .

This prior art LCD film packaging box is packed with impact-resistant materials such as styrofoam and embossed vinyl inside the packaging box to minimize damage caused by shipping, distribution, storage, and sales. There was a problem in that the time and cost for packaging increased.

Patent Registration No. 1299173 (registered on Aug. 16, 2013) previously applied by the present applicant installs a “┛”-shaped pedestal with the center protruding upwards and protruding from the bottom to both sides, and the floor is reinforced inside the pedestal. A support plate is installed, and a reinforcing plate for height correction is installed on the entire surface of the floor from the upper side of the support plate to the inside of the support plate.

On the outside of the pedestal, a corrugated cardboard reinforcing bar of several layers is laminated to reinforce the perimeter, and a bottom cover is formed so as to cover the upper and outer sides of the pedestal from the lower side of the corrugated cardboard reinforcing bar and cover the entire surface of the floor to form a reinforcing plate from the inside of the pedestal. The LCD (LCD) film was laminated and packaged inside.

The outer and upper surfaces of the bottom cover are covered with a lid to protect them, and the bottom cover and the lid are formed of corrugated cardboard.

However, these packaging boxes maintain their shape as the bottom surface is formed in three layers, such as the bottom cover, support plate, and reinforcement plate, but the middle part formed in three layers is severely bent downward during long-term storage and in a humid environment. During the process, the LCD film deformed downward, and as the packaging boxes were stored and moved in a stacked state of about 10 layers, they could not withstand the weight of the pedestal and corrugated cardboard reinforcing bars. .

And when the bottom plate is about to be bent, if sufficient rigidity is maintained at the edge of the slope, it prevents the bottom plate from bending and withstands bending depending on the weight of the product. am.
