EMBODIMENT OF THE INVENTION: TECHNICAL FIELD The present invention relates to a method of manufacturing a container and a container produced by the method, in particular, a foam layer formed on a surface of a substrate of the container . [Prior Art] Conventional disposable containers, such as disposable paper cups or disposable plastic cups, have been widely used in daily life, especially for cups and beverages that are not prefabricated and cannot be kept for a long time. Generally, most of the surface of the container will be printed with graphics to indicate seller information, content and other marketing information. Wherein, when the disposable container is filled with hot drinks, the container preferably has a moderate heat insulating effect, otherwise the user may have an uncomfortable feeling or a burn when holding the container. In order to improve the above problem, an additional foam layer is formed on the surface of the cup of the disposable container to moderately isolate the temperature conduction. For example, the applicants' application Nos. 94,143,974 and 96,102,426, both of which are hereby incorporated by reference in their entireties, are hereby incorporated by reference. Further, as disclosed in U.S. Patent No. 5,952, filed to U.S. Patent No. 5,592, the entire disclosure of which is incorporated herein by reference to the entire disclosure of the disclosure of the disclosure of the disclosure of the disclosure of the disclosure of the present disclosure. Although it has a heat insulation effect, how to mark the information on the surface of the container becomes a new topic. For example, in the 941th No. 4 and the No. 4 patent, it can be added to the surface of the container after adding the coloring material to the composite coating, or after the foaming, color _, for example, the surface of the silk is not flat. The foam layer 3 = is printed, which is caused by the inability to achieve excellent printing quality, and the printed image is burred or atomized, and if the image is only printed on the phase 2 foam When the layer is 'nen (four), the four machine sense, (4) method highlights the advantages of the three-dimensional foam layer. In addition, it is possible to add dyeing to the insulating layer, or to form the marking portion (10) ela (10) on the surface of the coffee, but it does not reveal how to form a better printed fruit on the green surface. The job will also have problems such as the above-mentioned poor printing and the inability to highlight the three-dimensionality. It is the primary focus of the invention that ‘printing directly on the surface of the foamed layer does not achieve the desired effect, so that the advantages of the foamed layer are more effectively exerted and the image information is highlighted. SUMMARY OF THE INVENTION The main object of the present invention is to provide a container manufacturing method for forming a three-dimensional image on a surface thereof and a container therefor. The manufacturing method provided for achieving the above object includes: mixing and mixing a liquid adhesive with a thermally foamed particle powder formed by coating a low boiling solvent in a thermoplastic polymer to form a composite coating, wherein the liquid adhesive Is selected from the group consisting of: Ju, B, Ethyl Acetate, Poly IU, and a mixture thereof; Coating: directly coating the composite on the outer surface of one of the substrates a coating, and the composite coating is surrounded by at least one hollow portion not coated with the composite coating; and foaming: at a foaming temperature higher than that of the thermally expanded particle powder, the composite material is applied to the outer surface of the substrate Forming a foaming effect to form a foamed layer having a hollow portion; 1337970 wherein a graphic is printed on the hollow portion, since the graphic of the hollowed portion is directly printed on a paper or a rotating substrate, such as (4) It is more beautiful, and with the hollowing out of the foam layer, it can further highlight the graphic printed in the hollow and achieve the stereo effect. [Embodiment] 百先' Please refer to the drawing. In the present invention, the manufacturing method of the container comprises the following steps: Mixing: coating the lyophilized polymer into the heat-expanding particle powder Mixing to form a composite coating: the filamentary binder is selected from the group consisting of polyvinyl acetate, ethylene-acetate, polydamine, and mixtures thereof, which may be aqueous or The composite coating is directly coated on the outer surface of one of the substrates, and the composite coating is surrounded by at least one hollow portion which is not coated with the composite coating; wherein the above-mentioned container refers to a molded product after molding or a semi-finished product of a container which is not yet formed, such as a cup or a bowl made of paper or plastic, or other containing utensil made of the material, and the semi-finished product of the container is used for processing cutting, for example. Continuous paper of paper-making cups; in addition, 'the above method of coating composite coatings' may utilize rollers, spraying, dipping, printing, air knives (air), extrusion, scraping or other suitable means; Foaming: at a foaming temperature higher than that of the thermally expanded particle powder, the composite material is foamed on the outer surface of the substrate to form a foamed layer having a hollow portion; wherein the above is higher than the heat generation The foaming temperature of the foamed particle powder varies with 1337970 % depending on the material used. However, the thickness of the foamed layer formed at the foaming temperature should be at least the thickness of the original composite coating. And the multiples are offered, and the secrets of the sisters are better, and the stereoscopic effect produced by them is more obvious. Wherein, between the coating step and the foaming step, a drying step may be further included, which is performed by drying at a foaming temperature lower than that of the heat-expanded particle powder, and the composite material is dry-bonded to the surface of the substrate. 'And formed - the surface has no (four) nature of the unfoamed layer, thereby facilitating the grain makers to pre-manufacture the unfoamed semi-finished product reserve, taking into account the inventory # stock. As shown in FIG. 2 and FIG. 3, a graphic is printed on the hollowed portion 2, and the graphic is a pattern, a pattern, a character or a combination thereof, and the graphic is not limited to the hollow portion 2, but may be The foam layer 3 is also disposed in a continuous pattern with the image in the hollow portion 2. The printing of the graphic can be carried out before the composite material is applied to the substrate, or at the composite material, or after the foaming of the composite material. In Fig. 4, when the composite material is printed before the coating, since the surface of the substrate is flat, the printed matter is simple, (4), and the composite material of the secret matching may be transparent or translucent. Thereby, the graphic in the foam layer has a see-through effect, and the graphic in the hollow portion has a sharper veranda and a vivid color 'is a graphic that can highlight the hollow portion.

As shown in FIG. 5, similarly, when the printing of the graphic is performed after the foaming, since the graphic on the foamed layer is compared with the graphic of the hollowed portion, since it has the chromatic aberration and the atomization effect, the same can be It highlights the graphic information in the hollow, and also has a three-dimensional visual effect. > In other words, the focus of the present invention is to form a convex foam layer on the surface of the grain by coating the composite material, and form a hollow portion at a suitable portion of the foam layer and at least in the hollow portion The printed graphic, wherein the outer shape of the hollow portion corresponds to the shape of the graphic printed therein, thereby highlighting the graphic in the hollow portion, and at the same time, the height between the foam layer and the hollow portion The difference between the difference and the color of the two pictures to play its three-dimensional characteristics. In addition, the reason why the present invention directly prints the graphic on the hollow portion is that part of the image is a temperature sensitive paint which can react to the temperature, and if the temperature sensitive paint is printed on the foam layer, the temperature is lost. And changing the color MS; conversely, if the temperature sensitive paint is printed in the hollow portion, the temperature in the container can be directly sensed to generate a corresponding color change, thereby indicating the temperature of the contents and avoiding the user's holding The foamed layer having a heat insulating effect is not aware of the problem that the temperature of the contents causes a hot mouth. Moreover, the container shown in FIG. 6 is exemplified by a cup, which comprises a crotch portion 4 surrounded by the base material and a bottom plate placed at the bottom end of the crotch portion 4, outside the crotch portion 4 7 1337970, the peripheral edge is formed with a foam layer 3, which further comprises a hollow portion 2, in which the graphic is printed, and the graphic corresponds to the outer shape of the hollow portion 2, so that the hollow portion can be made The graphics in 2 are more conspicuous and reach the goal of attracting attention. In summary, the invention combines the foam layer, the hollow portion and the graphic with the ingenuity, so that the foam layer has more stereoscopic characteristics, and at the same time emphasizes the graphic in the hollow portion, thereby not actually increasing Before the cost is raised, the overall value of the container made by using the manufacturing method is improved. The fact that the invention has been used has not been revealed, and the present invention has the progress of the invention, and it is necessary to approve the patent as soon as possible. In addition, the present invention has been described by way of example only, and is not intended to limit the scope of the present invention. _ The secret of the guardian.
