[Prior Art] According to the currently commercially available hollow molded plastic products, such as plastic bottles and other plastic products, the molding method used is divided into two. The first method is to first shoot the shaped embryo (as shown in Figure 1). The embryo A is placed in a molding die of a molding die B (shown in FIG. 2), and is blow molded by a hollow blow molding machine to form various hollow molded plastic articles in accordance with the shape of the molding. ¥Two methods are to directly inject the plastic material C into the molding cavity D0 of the mold D, and then blow the air from the hollow molding machine to form a hollow molded product. Only the plastic products E made by the above two methods are clear contents of the product E: such as commercially available soda, juice, mineral water in the process of filling the contents of the plastic product E, and the heat-shrinkable film F set in the plastic product E At the appropriate position of the plastic product E, the heat shrinkable film F is contracted to be bound to the plastic product E. I Only the heat shrinkable film F needs to be heated to the outside of the plastic product E. In contrast, when the plastic product E | warm; or slightly lower temperature environment, the shrink film and the plastic product E Refers to a kind of diameter; or in the range, it will be attached to the container (PET) plastic. 'The groove B 0 is then grooved B 0 (as shown in Fig. 2, which reveals the plastic, etc., all of which need to be heated by the outer surface to be bundled and placed in the usual beam-forming effect 1252804. 5. Description of the invention (2) It will be reduced, that is, the shrink film will be loosened, and the label of the plastic product E will disappear, causing trouble to the user. Therefore, the inventors of the present invention have been unable to fully integrate the current hollow blow molded plastic product with the label (shrink film). The problem is to study the present invention. f [ SUMMARY OF THE INVENTION The object of the present invention is to provide a label and a container (or a plastic product) which can be integrally molded at the same time in a hollow molding process, and the label and the container are sufficiently filled. The invention has the following features: 1. The method for integrally molding the container and the label of the invention, wherein the label is pre-formed into a cylindrical shape, and the through hole is formed, and the inner diameter of the through hole is smaller than the minimum of the container body. The outer diameter is smaller than the maximum outer diameter of the container body. 2. The method for integrally molding the container and the label of the present invention, wherein the label is pre-formed into a cylindrical shape by a material having appropriate ductility. The method for integrally molding the container and the label of the invention, wherein the shaped embryo system is placed in the mother mold, and the label can be placed in the sub-mold, and the mother and the sub-mold are combined, and the shaped embryo is formed in the shape of the container. The label is subjected to the function of outward extrusion and expansion, so that the label is closely attached to the container body to obtain a plastic container integrated with the label. [Embodiment] Thus, in order to enable the reviewing committee to fully understand the present invention, The following is a description of the following: Figures 6 and 7 show the label embodiment (1) and 1252804 of the present invention. 5. The invention description (3) (2) shows that the label 4 of the present invention is made of a malleable material. Prefabricated, such that the label 4 is formed with a ring 40, and the ring 40 is provided with a through hole 4 1 , and the inner diameter D of the through hole 41 is the same; or slightly smaller; or Slightly larger than the minimum outer diameter D 1 of the container body 50 to be covered by the label; or the inner diameter D of the through hole 41 is slightly smaller than the maximum outer diameter D of the container body 50 to be the label of the container 5 2. or slightly I is greater than the maximum outer diameter of the shaped embryo 3. Attack: the container 5 (shown in FIG. 8) includes a container body 50 and a head portion 5 1 , and the container body 50 referred to herein is a covering portion of the label 4, and the area of the covering portion can be The size and volume of the label are determined. Thus, the mold used in the manufacturing method of the present invention is as shown in FIGS. 9 to 12, and includes a mother mold 1 and a sub-mold 2, wherein the mother mold 1 is provided with an inner mold groove 10 and an inner mold. The tank 10 is provided with an injection port 11 for inserting and clamping the shaped blank 3, which is convenient for forming a container 5 (or a plastic product) by a hollow blow molding machine. The sub-mold 2 is provided with a molding groove 20, which can be formed by using the molding. The mold groove 20 is pre-positioned for the label 4. Therefore, while the mother mold is placed in the molding blank 3, the molding cavity 20 of the sub-mold 2 is preliminarily placed in the label 4, and the embryo 3 to be formed is blown into the tube 1 2 blowing and molding process (as shown in FIG. 11), when the shaped embryo 3 is gradually formed according to the shape of the container 5, the container body 50 portion of the container 5 will have the function of outwardly squeezing and expanding the label 4. The label 4 is sufficiently bonded to the container body 50 (as shown in Fig. 8) to produce a container integral with the label. Of course, in order to make the aforementioned label and container can be smoothly combined, it is preferable that the I container can be made of polyethylene or polypropylene or PET material or other materials suitable for 1252804, invention description (4) i, Therefore, the label is preferably made from the above materials. Of course, if the label is different from the material of the container, the structure of the label can be changed by processing techniques, such as a label made by synthesizing, and the label and the container described above. The bonding surface and the bonding layer of the same material as the container can be processed to solve the problem of the combination between the label and the container. The advantage of the method is that when the container body 50 of the i container 5 (or the plastic product 5) is in the shape of a non-tubular shape, that is, the container body 50 forms a surface having a plurality of different outer diameters D1, D2, D3 i, etc., The shaped embryo may be the same as the through-hole perforation 4 1 in the shape of the container shape; or slightly smaller than; or slightly larger than the minimum outer diameter D 1 of the container body 50; or the inner diameter D of the through-hole 4 1 is slightly smaller than the container 5 To the outer diameter D2 of the container body 50 of the label package t; or the label 4 of the inner diameter D of the through hole 41 which is slightly larger than the maximum outer diameter of the shaped embryo 3, the function of outwardly squeezing and expanding the closeness is made to make the label and the container The body is fully combined to produce a container integrated with the label. As a result, the label 4 of the plastic product does not fall off from the surface of the container 5 (plastic product 5), and the value of the container 5 (plastic product 5) can be increased. Furthermore, the present invention can be used in a large number of containers that focus on packaging hygiene and safety, such as foods; or medicines; or health foods, etc., with no secondary processing labeling, or after the container is molded, no need to The transfer technology prints a decorative pattern on the surface of the container or otherwise shrinks the shrink film to cover the outer surface of the container, thereby improving the value of the container and the safety of use. 1252804 Brief description of the schema <Graphic> 丨 First 囵: view of the shaped embryo.
