PROBLEM TO BE SOLVED: To restrain the cost of a vessel from increasing, and at the same time enhance the productivity of a pollution prevention vessel by forming a resin layer added with an antibacterial agent or a mildew proofing agent on a par of the exterior surface of a vessel through an intermittent extrusion method or the like. SOLUTION: In a vessel consisting principally of plastics used in a water section such as a bath room or sink, resin added with a drug such as an antibacterial agent or a mildew proofing agent is partially formed on a shoulder part A and bottom part C of a vessel because the bacterial fouling of a vessel concentrates in the bottom part C and shoulder part A of a vessel. Namely, the shoulder part A and bottom part C are formed by laminating an HDPE layer 1a added with thiabendazole, and HDPE layer 1b added with reproduced resin, an antistatic agent or the like, and an HDPE layer 1c having no addition of drugs. This resin layer added with an antibacterial agent or a mildew proofing agent is preferable to be formed on a part of the vessel outer layer surface through intermittent extrusion method. Also, an outer surface layer except the resin layer added with an antibacterial agent or a mildew proofing agent is preferable to be polyethylene, etc. |
