Description

Electric paper and its carton

The present invention is a paper, especially an electrical paper and an electrical paper box made using the same.

In commercial sales, commodity packaging is an important part, playing an important role in the added value of goods. In conventional technology, the important function of the packaging of goods is to protect the goods themselves from damage. However, as modern people's requirements for the quality of goods are increasing, packaging is not just about protecting goods for modern people. In other words, if a product has a good packaging, it can not only protect the goods, but also enhance the quality of the business, which is of great help to sales.

Moreover, although the conventional wrapping paper or packaging box has a texture design and a good aesthetic pattern, it can produce a visual effect that attracts consumers, but most of the conventional wrapping paper or packaging box is discarded after being used. Cause waste. For example, the Republic of China New Patent Publication No. 471457 "Structural Improvement of Gift Packaging Box" relates to a structural improvement of a gift packaging box, and more particularly to a carton structure for packaging, which comprises a box body and a cover body. Composed of. The box body and the cover system are formed by rolling a pair of strips through a mold, and the formed side strips can be adhered to the board body to form the box body and the cover body, and the cover body can be covered by the cover body. On the box. The cover can be printed with a pattern to increase the visual effect of the package.

However, although the surface of the above-mentioned carton is printed with a variety of patterns, it cannot be changed after one printing. In addition, even if there is drift The bright pattern, but it can't be changed, so it can be reused after use, but it can't be used by users after using it several times. In addition, most of these conventional packaging cartons cannot be reused for a long time, and the life is short, which inevitably increases the waste of paper resources. In summary, there is a need for an electrical paper and its packaging cartons to address the deficiencies of conventional techniques.

The invention provides an electric paper which has a conductive structure and can provide optical or sound effects by electronic components (such as light-emitting elements or sound-emitting elements) disposed inside or on the surface by the supply of direct current power, thereby increasing the use of the paper. Diversity. In addition, a concave-convex structure may be provided on the outer surface of the paper to create a three-dimensional effect corresponding to a pattern or a character on the surface of the paper, thereby increasing the aesthetic effect of the electrical paper. In addition, the design of the concave-convex structure can increase the flexibility of the electrical paper and strengthen the structure of the paper, and increase the recyclability of the electrical paper, thereby reducing waste of environmental resources.

The present invention provides an electrical carton which is folded using an electrically conductive paper having a conductive structure. Through the electrical design of the electrical paper, the electronic components (such as light-emitting components or sound-emitting components) disposed on the paper are actuated, thereby making the packaging carton attractive. In addition, since the carton has a concave-convex structure, on the one hand, the strength of the paper can be increased, and it is not necessary to use thick paper to form a carton of similar strength. In addition, by the design of the concave-convex structure, the flexibility of the paper can be increased, so that the paper box can absorb the external impact force and reduce the amount and thickness of the cushioning material used in the paper box.
