Cardboard and paper packaging box ribs with heavy acceptance times}

The present invention relates to a heavy-weight packaging box for recovery using a corrugated cardboard and a paper reinforcement, and more particularly, to cut and fold the line to form a reinforcement support and a reinforcement cover using a paper reinforcement formed by laminating paper and forming a "┓" type. The cardboard reinforcement and the cardboard reinforcement cover are formed by fixing with tacopin or adhesive inside the rectangular molded product molded through the cardboard, and the vertical reinforcement wall cardboard on both sides of the reinforcement wall cardboard inside the cardboard reinforcement support and the cardboard reinforcement cover. It is molded to be folded and unfolded at the reinforcement wall cutouts and corners of the vertical reinforcement wall cardboard and used as a packing box when it is used as a packaging box. Recovery using paper and paper reinforcement It relates to a heavy crate.

In general, packaging refers to technologies and conditions that market appropriate materials or containers to the goods in order to protect their value and condition in transporting and storing the goods, including open, interior, exterior There are three.

The basic function of the packaging as described above is in the protection, merchandise, convenience, psychology and deliverability of the packaging. Previously, the packaging's functionality and small and medium size had been put on protection, and that was enough, but today it is being expanded to focus on promotional functions. It is difficult to say that the product itself is a commodity alone, and it can be said that it is commercialized only when it is packaged.

The LCD film in the packaging is an electrical device that transmits various electrical information generated by various devices to the visual information by using the change in the transmittance of the liquid crystal according to the applied voltage. It is a kind of flat panel display which is widely used because it does not have self-luminescence but requires a backlight, but it is low in power consumption and convenient to carry. It is used for watches, computers, and various electronic devices.

It refers to a type of flat panel display widely used for screens of LCDs. Among the components of LCD, the packaging of the LCD wide viewing angle compensation film, the brightness enhancement film, and the liquid crystal film is a high-precision part that can be damaged even with a small impact. Has been packed in a state filled with impact resistant material to prevent the impact inside.

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

In addition, the packaging box as described above is made of paper and corrugated cardboard in the process of packaging and transporting heavy materials as well as the LCD film, so that the ability to respond to the weight is reduced, the size (volume) of the box is not reduced after using the heavy materials Since the cost of recovery is more expensive to recycle, it was a very unreasonable drawback in terms of resource recycling.

In order to solve this drawback, as recently as patent registration No. 0793239 (registered on Jan. 03, 2008), it is possible to change the size of the box according to the addition of the prefabricated panel, and Patent Registration No. 11129494 (2012). 02. 22. Registration), it is made of plastic, and it can be used by transporting cargo by removing it from the pallet and then reducing the volume by folding it when the plastic multi-stage box is collected and stored.

However, such a conventional product has a drawback in that the cost is increased because the material is made of plastic and wood, etc., and has a disadvantage in that it is used integrally with the pallet at the lower side with the disadvantage of providing a very complicated structure through injection molding.

In particular, in the case of a wooden box, it is hard to store and transport products by packaging. However, when exporting to a foreign country, if the wooden material is made of wood, it must be shipped after the disaster prevention work in Korea. In the case of arriving after this time, there is a drawback that the disaster prevention work must be carried out again before customs clearance in the field, so it was very inconvenient and difficult to apply.
