Method for forming a core vessel with different colors

A method for forming a core vessel with different colors comprising the following steps:

• A, initially forming an inner parison of a vessel by using one die:
• employing a first die (not shown) to injection mold an inner parison of a vessel, wherein at the bottom of said inner parison is formed a cavity;
• B, secondarily forming a core parison of the vessel by using another die:
• placing said inner parison into a second die (not shown), and by way of the colorful homogeneous material which is different from the color of said inner parison, injection molding a core parison, wherein the top portion of said core parison which is joined together with said inner parison is fixed to said cavity of said inner parison;
• C, finally forming an outer parison of the vessel by using the other die:
• placing the combined inner and core parisons into a third die (not shown), and by means of the same colorful homogeneous material as said inner parison, injection molding an outer parison, wherein said outer parison tightly covers the exteriors of said inner and core parisons, and said inner, core and outer parisons are completely combined together without forming any seam therebetween, such that after the finished vessel is released from the die, it will have a colorful suspended core therein.
