Title:

PRODUCTION METHOD FOR HEAT RESISTANT CONTAINER

Document Type and Number:

WIPO Patent Application WO/2012/002164

Kind Code:

A1

Abstract:

Disclosed is a production method for a heat-resistant container whereby a reduction in internal pressure displaces a false bottom inward. The production method is characterized by: the formation of a false bottom (11) that is thinner than a surrounding wall section (12a) by a first blow-molding that uses a heat-treating blow-molding mold and, when a second blow-molding using a final blow-molding mold is performed, the pushing up of the false bottom (11) by a secondary bottom mold, and the increase in the thickness of the surrounding wall section (12a) (contact section (12)) in relation to the false bottom.
