Manufacturing method of environment-friendly container with 3D color printing picture and environment-friendly container

Abstract

The invention relates to a manufacturing method of an environment-friendly container with a 3D color printing picture and the environment-friendly container. The method comprises the steps of printing, spraying, forming, reinforcing and demolding. According to the printing step, the picture is printed on one side of a transparent film with thermosensitive color-changing printing ink by means of twice overlapping printing at room temperature, wherein the transparent film is made of PP materials, PET materials, PVC materials and PS materials. According to the spraying step, coating liquid formed by heat-melting of materials which are used for manufacturing the transparent film is atomized and evenly sprayed onto the side, with the picture, of the transparent film by means of over 1.2 atmospheric pressure to form a protective layer from a position 20-30 cm away the transparent film. According to the forming step, the transparent film is coiled to form a cylindrical shape on a mold, an upper base is attached to the coiled transparent film, and then the container is fixed and formed. According to the reinforcing step, an opening injection molding ring is formed at the opening end of the container in an injection molding mode, and reinforcing ribs extending from the opening end to the bottom are formed on the inner wall of the container in an injection molding mode.

Description

technical field [0001] The invention relates to a method for making a container and the container, in particular to a method for making an environment-friendly container with 3D color printing and the container. Background technique [0002] In people's daily life, various container products are often used for holding articles or liquids, for example, water cups and kettles for holding water, trash cans for holding garbage, paper buckets, etc. The surfaces of these products are either colored or printed to increase their aesthetic feeling, but the patterns on the surfaces do not have a three-dimensional effect. Therefore, in order to improve the aesthetics, taste and artistic effect of the product, the patent No. ZL200420054171.4 discloses a three-dimensional picture container, which is a plastic 3D color cup body, and is compounded with a three-dimensional picture on the surface of the 3D color cup body. Grating plate; 3D color cup body and grating plate are compounded by ...

Problems solved by technology

When this kind of product is heated, the quality of the three-dimensional pattern will be affected. At the same time, the production of a container with a three-dimensional picture requires multi-layer films or plates, and there are many raw materials.

[0003] In addition, at present, whether it is paper products or plastic products, cup products are bonded by glue. When they are used to hold food or water, due to the presence of chemical substances in different degrees in heat sealing or glue, a large amount of harmful substances will be precipitated when heated. Adverse effects on human health, and the structure is not strong enough
