Film packaging box for liquid crystal display products by corrugated paper}

The present invention relates to a film packaging box for liquid crystal display products by cross-laminating corrugated cardboard, and more particularly, even if the produced LCD (Liquid Crystal Display) film is stacked in several layers in the process of storing and transporting it. The present invention relates to a film packaging box for liquid crystal display products by cross-laminating corrugated cardboard, in which the bottom and rim of the packaging box are not easily deformed because they are not affected by weight, and the LCD film can be safely stored.

In general, packaging refers to the technology and state of supplying goods with appropriate materials or containers to protect the value and condition of goods in transportation and storage, which includes opening, interior, and exterior There are three.

The basic functions of the packaging as described above are protection, marketability, convenience, psychology, and delivery of the packaging. In the past, the function and smallness of the packaging were placed on protection and that was sufficient, but today it has been further expanded and focuses on sales promotion. It is difficult to say that a product is a product by itself, and it can be said that it is commercialized only when it is packaged. Therefore, the packaging becomes a product only when it is integrated with the contents, so the marketability of packaging is also an important function.

Among these packaging, the LCD film, the film for liquid crystal display products, is an electric device that converts various electrical information generated from various devices into visual information by using a change in transmittance of liquid crystal according to an applied voltage and transmits it. It is a type of flat panel display that is widely used because it does not self-luminous and requires a backlight, but consumes less power and is convenient for portability. Packaging of LCD wide viewing angle compensation film, luminance enhancement film, and liquid crystal film are high-precision parts that can be damaged even by small shocks. .

In order to minimize damage caused by shipping, distribution, storage, and sales processes, the packing box for LCD film of the prior art is packed with impact-resistant materials such as Styrofoam and embossed vinyl inside the packing box. There was a problem of increasing time and cost according to packaging.

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

On the outside of the pedestal, several layers of corrugated cardboard reinforcement are laminated to reinforce the circumference, and a bottom cover is formed to wrap the upper and outer sides of the pedestal at the lower side of the corrugated cardboard reinforcement and cover the entire surface of the floor, Reinforcement plate from the inside of the pedestal On the upper side of the LCD (LCD) film was laminated and packed inside.

The outer and upper surfaces of the bottom cover are covered and protected with a lid, and the bottom cover and the lid are made of corrugated cardboard.

However, the bottom of such a packaging box is formed of three layers, such as a bottom cover, support plate, and reinforcing plate, so the shape is maintained, but the middle part formed of three layers is severely bent downward during long-term storage in a humid environment. While doing so, a defect occurred that the LCD film was deformed to the lower side, and as the packaging box was stored and moved in a stacked state of about 10 layers, it could not withstand the weight of the pedestal and corrugated cardboard reinforcement, making it impossible to laminate and use films of 70 inches or more. .

In addition, when the bottom plate is about to bend, if sufficient rigidity is maintained at the edge of the slope, the bottom plate is prevented from bending and the bending according to the weight of the product is endured. am.
