According to this configuration, when the release agent is applied to the mouth mold 21, adhesion of the mold release agent to unintended portions other than the mouth mold 21, for example, the plunger 16 can be suppressed. As a result, it is possible to suppress the generation of the inner surface contamination and the inner surface foreign matter of the parison 102, that is, the generation of the inner surface contamination and the inner surface foreign material of the glass bottle 103.
- the strength reduction of the glass bottle 103 can be prevented.
- PB press blow molding
- NPB narrow neck press blow molding
- the adhesion between the plunger 16 and the parison 102 is deteriorated due to the mold release agent attached to the plunger 16, Can suppress molding defects due to insufficient solidification.
- the release agent is applied to the mouth mold 21 by the application device 40. That is, the worker does not need to manually apply the release agent to the mouth mold 21 manually, and the burden on the worker for applying the release agent can be reduced, and the safety of the worker in applying the release agent can be improved. It can improve more.
