Beschreibung
Zusammenfassung:	The present invention provides: a mold release lubricant application device which is for a rough mold for glass bottle manufacturing and in which a change in the wall thickness of a glass bottle skirt part is reduced after applying a mold release lubricant; a mold release lubricant application method for a rough mold for glass bottle manufacturing; a device for manufacturing glass bottles; and a method for manufacturing glass bottles. In this mold release lubricant application device 5 for a rough mold for glass bottle manufacturing, a mold release lubricant is applied to a first region 41 set on a mold opening 11 side on the inner surface of a rough mold 10, and a second region 42 set at a location further away from the mold opening 11 than the first region 41, so that a mold release lubricant film thickness T1 in the first region 41 is greater than a mold release lubricant film thickness T2 (including zero) in the second region 42.
