<p>PROBLEM TO BE SOLVED: To provide a light-shielding container in which a re-grind resin generated during manufacturing of the container is utilized to reduce its cost and it has a higher degree of whiteness at the outer surface of the container. SOLUTION: There is provided a light shielding resin container comprised of an inner layer 6, an intermediate layer 7 made of black pigment compound resin and an outer layer 8 made of titanium dioxide compound resin, wherein a layer 9 made of re-grind resin is installed between the intermediate layer 7 and the outer layer 8, the re-grind resin has an L* value of 20 or more measured by a colorimeter and an L* value measured by a colorimeter calculated in reference to the outer layer 8 of the container is 85 or more.</p> |
