ABSTRACT:
A method for manufacturing a transparent acrylic container having colored bubbles includes the following steps: (A) preforming a plurality of colored beads, (B) forming a container made of transparent acrylic material, (C) adding a foam agent and the colored beads into the container such that the foam agent produces a plurality of transparent bubbles, and (D) curing the container to produce a container product containing a mixture containing the transparent bubbles and the colored beads, thereby producing a visible effect of colored bubbles. Thus, the transparent bubbles are mixed with the colored beads to produce a visible effect of colored bubbles, thereby enhancing the aesthetic quality of the container product.
