SYNTHETIC RESIN CONTAINER

摘要

PROBLEM TO BE SOLVED: To give peculiar warmth to the touch and add depth to the color and give a high-grade and deep feel to a container, by mixing specified mineral powder with synthetic resin to produce the container. SOLUTION: Tourmaline, a silicate mineral, having an electric chargeability is mechanically crushed to obtain particles of 0.01-500μm, preferably 0.1-50μm. This tourmaline powder is calcinated when it is required and the material colored in red or pink is mixed with synthetic resin pellet or powder and further, mixed with an additive such as a colorant when necessary to make a raw material. And the raw material is molded in a molding device to produce a container. The using quantity of tourmaline powder is 0.001-10wt.% of synthetic resin pellet or powder, preferably 0.1-5wt.% or more preferably 0.2-0.5wt.%.
