<p>By preventing drops of water falling from an upper funnel, defect-free gobs are prevented from being falsely determined to be defective in a gob inspection device, and efficiency of glass product manufacture is improved. An annular groove is formed at the bottom end of a tubular upper funnel and the top of said groove opens into the upper funnel. By catching water drops that run downwards along the inner surface of the upper funnel inside of said annular groove, since water sprayed with a shear spray or a cooling spray and entering into the upper funnel is caught in the annular groove, water drops falling from the bottom end of the upper funnel are eliminated.</p> |
