<p>PROBLEM TO BE SOLVED: To simply and inexpensively obtain a blow molded product equipped with a photocatalyst by introducing a pressure gas containing a photocatalyst into a parison to embed the photocatalyst in the inner surface of the parison. SOLUTION: A drinking container 200 is a bottle made of polyester and a photocatalyst 201 is provided to the inner surface of the container and, as a member constituting the drinking container 200, an arbitrary light pervious member such as polyethylene terephthalate, an acrylic resin polycarbonate, polyvinyl chloride or a urea resin is used. As a first means equipped with a photocatalyst on the inner surface side of the container, an adhesive member containing the photocatalyst is applied by spraying or an adhesive member containing the pohotocatalyst and a diluting solvent is injected into the container and, after the container is closed by a lid, the container is shaken or tumbled to apply the photocatalyst to the inner surface of the container. The coating thickness of the adhesive member containing the photocatalyst is set to 0.1-100μm.</p> |
