<P>PROBLEM TO BE SOLVED: To provide an inspection method and an inspection apparatus of a resin-coated glass bottle capable of reliably inspecting whether a resin-coated film is formed on the surface of the bottle to the bottle in which a transparent glass bottle is coated with a transparent and colorless resin. <P>SOLUTION: In the inspection method of the resin-coated glass bottle, steam is sprayed to the surface of the glass bottle that has completed a resin-coating treatment process for generating a blur on the surface, and the degree of blur is detected optically, thus discriminating the presence or absence of the resin-coated film on the surface of the glass bottle. The inspection apparatus of the resin-coated glass bottle comprises an ejector 1 for spraying steam toward the surface of the glass bottle 10 that has completed resin-coating treatment; and a detector that is positioned directly after the ejector 1 and optically detects the degree of blur in the glass bottle 10. <P>COPYRIGHT: (C)2007,JPO&INPIT |
