Abstract: A method for making a dual-color melamine container includes (1) making an inner part of container with a first mold by injection molding; the male part of the first mold being formed with several projecting patterns thereon so that the inner part of container is formed with holes having patterns, (2) attaching patterns to an inner side of the inner part of container, and (3) repositioning the inner part in a second mold, and forming an outer part of container over the inner container part, and attaching patterns to an outer side of the outer container part; thus, the inner part can be made dial-color with injection molding if melamine materials used in both injection molding processes are different colors.

Abstract: A method for making a melamine container with dual-side patterns including four steps, which are (1) making a first part of a melamine container, (2) forming patterns on the first container part, (3) making a second part of the melamine container, and (4) forming patterns on the second container part. More specifically, the first container part is formed in a first mold, and a male part of the first mold is removed to uncover an inner side of the first container part for allowing patterns to be attached on the inner side. Then, the first container part is repositioned in a second mold so that the second container part is formed over the first container part. A female part of the second mold is removed for allowing patterns to be attached to the outer side of the second container part.
