<p>PURPOSE: To improve the antibacterial function, effectiveness of the action and durability of the effect by applying an undercoating layer on the outer circumference of a glass vessel, forming a coating layer composed of a top layer containing an antibacterial agent on the undercoating layer and baking the product. CONSTITUTION: The objective glass vessel is produced by forming a coating layer composed of a resin composition containing >=0.2% antibacterial agent and a surface-roughening agent selected from silica gel, titanium oxide, etc., and/or an anti-settling agent selected from materials composed mainly of organic bentonite, polyamide wax, hydrogenated castor oil wax, etc., on the outer circumference of a glass vessel and subjecting the product to baking finish. For example, a resin composition composed of melamine resin, acrylic resin, etc., and titanium oxide, a hardener and a coupling agent is applied to the outer circumference of a cosmetic cream bottle made of soda glass and obtained by electrostatic coating to form an undercoating layer. A thin top-coating film produced by kneading a zeolite-silver ion antibacterial agent with the resin composition same as above is formed on the surface of the undercoating layer and the product is heat-treated at 180 deg.C for 20min.</p> |
