Description of the Invention: [Technical Field] The present invention relates to a container structure and a molding method thereof, and more particularly to a container structure of all related plastic injection molded products made by using in-mold labeling technology and Its molding method. [Prior Art] Traditional commercial plastic grain products are mostly printed or printed on a plastic container that has been molded, or a plastic film with printed characters and patterns has been applied to it. The way the molded plastic container is used to remind the basic information of the product and increase its commercial added value. However, the above methods have their own shortcomings. The color and pattern that the former can present are limited, and cannot meet the diversified needs of today's products. The latter is presented in a conforming manner, which is not only costly but also difficult to align when fitted. The gap affects the aesthetics, and the surface of the plastic film is smooth. The related industry has developed a new type of technology: In-Mold Labeling, which uses a multi-layer plastic synthetic film (referred to as a plastic film) that has printed characters and patterns. The label is placed in the plastic molding die and the molten plastic is injected into the mold in an injection molding manner, for example, and the plastic synthetic film label and the plastic body are molded by high temperature and high pressure, that is, the plastic molded product having the refined appearance is completed. . In addition, the use of its integrated molding characteristics can also achieve the advantages of easy anti-counterfeiting and greatly reduced cost. The ring 1289132 has good strength and is not easily damaged. Therefore, it has gradually become the mainstream technology in the market in recent years. SUMMARY OF THE INVENTION An object of the present invention is to provide a container structure and a molding method therefor, by which the variability of a plastic molded article in design can be improved to enhance a visual effect. SUMMARY OF THE INVENTION An object of the present invention is to provide a container structure and a molding method therefor, whereby the invention is simplified to simplify the process and the appearance of the plastic molded article is more refined. SUMMARY OF THE INVENTION An object of the present invention is to provide a container structure and a molding method therefor, whereby the plastic molded article has a better touch and is convenient for the consumer to use. SUMMARY OF THE INVENTION It is an object of the present invention to provide a container structure and a method of forming the same, whereby the product has a better anti-counterfeiting function. The invention relates to a container structure and a molding method thereof, which are subjected to electric discharge machining (also called discharge flower) at a suitable position of a mold in a plastic molding machine or by solvent etching (also called etched flower) to make the inner side wall of the mold Forming a etched area with a large surface roughness; then, placing a printed film with a printed text and pattern into a suitable position in the mold; then injecting molten plastic into the mold, and using the high temperature and high pressure to make the molten plastic and the label The mold is integrally formed to form a container structure (e.g., a related plastic injection molded product), and a surface region of the mist 1289132 corresponding to the etched region is formed on the outer wall surface of the container structure. In the container structure prepared by the above molding method, the label film is attached to the outer wall of the body in an integrally formed manner to form a container structure, and a matte area is formed on a partial area outside the label film to achieve better vision. And touch effects. [Embodiment] In order to obtain a more specific understanding of the present invention, one or more preferred embodiments are illustrated in the accompanying drawings. In addition, the present invention may be widely practiced in other embodiments in addition to the detailed description below. Please refer to the first figure for a flow chart of the molding method of the container structure of the present invention. The molding step is as follows. First, in the inner mold 10 of the plastic molding machine, a desired etching region 12 (also referred to as an etched region) is formed at a predetermined position of the side wall 11 of the mold 10 by electric discharge machining. The etched region 12 has a larger surface roughness than the unprocessed region. As shown in FIG. 2A, the surface roughness and position distribution of the etched region 12 can be appropriately controlled according to requirements. In the present embodiment, the plastic cup is taken as an example, so that the shape of the mold 10 is simply presented in a cup shape for convenience of explanation, and the actual mold 10 is not limited thereto. Further, in addition to the discharge processing method, the mold 10 may be directly etched using an etchant solvent to form the etched region 12. Next, the label mold 20, which has been printed with characters and patterns, is placed in the mold 10 as shown in the second drawing B, and is suitably fixed on the surface of the side wall 11 inside the mold 1289132 10 to make the immersion area. 12 is opposite to the surface on which the label film 20 is printed with characters or patterns, as shown in the second c, followed by molten plastic such as polyethylene (PE), polypropylene (PP) or polyethylene terephthalene. A plastic material such as an acid ester (PET) is injected into the mold 10 from the gate 13 by injection molding to form the body 30, and the label film 20 and the body 30 are integrally molded by high temperature and high pressure during injection molding. The container structure 40 is formed, and at the same time, the characters and patterns of the label film 20 are circumferentially presented on the outer wall of the body 30. Moreover, due to the action of the etched region 12 in the mold 10, the label film 20 is subjected to high temperature and high pressure, and a matte surface 21 corresponding to the surface roughness of the etched region 12 is formed on the surface (also referred to as etched flower). The face or discharge face, that is, the matte zone 21, is formed on the outer wall of the container structure 40, as shown in the second D. By using the matte surface 21 formed on the label film 20 in the above manner, the plastic product can have a larger visual change space when the outer shape is designed, thereby improving the quality and added value of the quotient, and at the same time, the surface roughness of the label mold 20 The change allows the user to easily hold and fix the convenience of use. Referring to the examples shown in FIG. 3A and FIG. 3B, the matte area 21 can exhibit a simple geometric arrangement change, such as a square arrangement or a circular arrangement, and the like, and even the matte area 21 can be further controlled. The surface roughness of the detail makes it appear in various patterns, such as leather flowers, tartan flowers or wood grain flowers. Therefore, the container structure related plastic injection molding product obtained by the molding method of the present invention, the label film 20 is integrally formed and attached to the outer side of the 1289132, and on the outer wall surface of the container structure 40, that is, the outer surface of the label film 2 The partial area forms a matte area 21. The label film 2 is mainly composed of a bonding layer, a decorative layer and an outer protective layer, and a metal layer such as an aluminum layer or a tin film may be further disposed between the decorative layer and the outer protective layer to increase the label film 20 Pattern variability. The container structure of the present invention and the molding method thereof are not limited to the cup body, and any plastic or all plastic containers can be implemented. Based on the above, the container structure of the present invention has better appearance, design, and performance, and is suitable for plastic injection molding formed by in-mold labeling. The scope of application of the present invention is not limited to the embodiments described above, and the effects and effects achieved by the present invention are equivalent or equal, or are variants or improvements of the present invention. The scope of the invention is covered: In summary, the invention conforms to the provisions of the patent law, and the application is filed according to law, and it is expected to grant the patent as soon as possible. ^ 9 [_式单单说明] The first figure is a flow chart of the container structure forming method of the present invention.
