Abstract
Official abstract text for this publication.
A blow molding device includes a blow molding mold to which a bottomed tubular preform is fitted, a blow nozzle that is fitted to a mouth tubular portion of the preform fitted to the mold, and a pressurized liquid supply unit configured to supply a pressurized liquid to the blow nozzle. The preform is to be molded into a shape conforming to a cavity of the mold by filling the liquid into the preform through the blow nozzle. The blow molding device further includes: a deaeration mechanism that is connected to the blow nozzle. The liquid is filled into the preform through the blow nozzle after air that is present within the preform fitted to the mold is sucked out by the deaeration mechanism.
First claim
Opening claim text (preview).
The invention claimed is: 1. A blow molding device including a blow molding mold to which a bottomed tubular preform is fitted, a blow nozzle that is fitted to a mouth tubular portion of the preform fitted to the mold, and a pressurized liquid supply unit configured to supply a pressurized liquid to the blow nozzle, the preform being to be molded into a shape conforming to a cavity of the mold by filling the liquid into the preform through the blow nozzle, the blow molding device comprising: a deaeration mechanism that is connected to the blow nozzle, wherein the liquid is filled into the preform through the blow nozzle after air that is present within the preform fitted to the mold is sucked out by the deaeration mechanism, and the deaeration mechanism has a function of supplying flush air into a flow path connecting the deaeration mechanism and the blow nozzle to return the liquid within the flow path to the blow nozzle after filling the liquid into the preform. 2. The blow molding device of claim 1 , further comprising: a stretching rod that is arranged coaxially with the blow nozzle and that is displaceable into the cavity of the mold to stretch the preform axially.
