Abstract
Official abstract text for this publication.
A manufacturing apparatus for manufacturing a resin container including an injection molding part configured to injection-mold a preform, and a temperature adjustment part configured to adjust a temperature of the preform molded in the injection molding part. The manufacturing apparatus is configured to blow-mold the preform whose temperature has been adjusted in the temperature adjustment part. The injection molding part includes an injection core mold and an injection cavity mold, and both the injection core mold and the injection cavity mold include a flow path connected to a chiller in which coolant is configured to flow to cool the preform such that the preform is inserted into the temperature adjustment part in a state where an outer surface temperature of the preform is higher than a glass transition temperature of a material constituting the preform by 30° C. or higher and 60° C. or lower.
First claim
Opening claim text (preview).
The invention claimed is: 1. A manufacturing apparatus for manufacturing a resin container, the manufacturing apparatus comprising: an injection molding part configured to injection-mold a preform; and a temperature adjustment part configured to adjust a temperature of the preform molded in the injection molding part, wherein the manufacturing apparatus is configured to blow-mold the preform whose temperature has been adjusted in the temperature adjustment part, wherein the injection molding part includes an injection core mold and an injection cavity mold, and both the injection core mold and the injection cavity mold include a flow path connected to a chiller in which coolant is configured to flow to cool the preform such that the preform is inserted into the temperature adjustment part in a state where an outer surface temperature of the preform is higher than a glass transition temperature of a material constituting the preform by 30° C. or higher and 60° C. or lower, wherein the preform is cooled to a predetermined temperature suitable for blow molding in the temperature adjustment part. 2. The manufacturing apparatus for manufacturing the resin container according to claim 1 , wherein the temperature adjustment part is configured to sandwich the preform with a temperature adjustment core mold and a temperature adjustment cavity mold to compression-deform the preform. 3. The manufacturing apparatus for manufacturing the resin container according to claim 1 , wherein the temperature adjustment part is configured to circulate air inside the preform. 4. A manufacturing method for manufacturing a resin container, the manufacturing method comprising: injection-molding a preform; adjusting a temperature of the preform to which the injection-molding has been performed in a temperature adjustment part; and blow-molding the preform whose temperature has been adjusted, wherein the preform is inserted into the temperature adjustment part in a state where an outer surface temperature of the preform is higher than a glass transition temperature of a material constituting the preform by 30° C. or higher and 60° C. or lower; and wherein the preform is cooled to a predetermined temperature suitable for blow molding in the temperature adjustment part. 5. The manufacturing method for manufacturing the resin container according to claim 4 , wherein the temperature adjustment part is configured to sandwich the preform with a temperature adjustment core mold and a temperature adjustment cavity mold to compression-deform the preform. 6. The manufacturing method for manufacturing the resin container according to claim 4 , wherein the temperature adjustment part is configured to circulate air inside the preform.
