Abstract
PURPOSE:To enable the uniform inflation of a container having wide thickness, by a method wherein, when a container in wide thickness, made of noncrystalline synthetic resins, which is manufactured beforehand, is inflated, heating temperatures at an internal surface side and an external surface side of the container in wide thickness are specified. CONSTITUTION:When, after a container 1 having wide thickness, made of noncrstalline synthetic resins, which is produced beforehand, is heated, the container 1 is inflated in a mold 3 to produce a synthetic resin product, a heating condition for the container in wide thickness is determined from a formular, that is, TL=HDT+ K, -10 deg.C<=K<=50 deg.C, TH=TL+L, 30 deg.C<=L, TH<=DT, where HDT deg.C is a thermal deformation temperature of the noncrystalline synthetic resins, for use with a material for a product, DT deg.C is an analysis temperature of said noncrystalline synthetic resin, TH deg.C is a surface temperature at a heating side and TL is a surface temperature at a side which is opposite to the heating side, in case the container 1 in wide thickness is heated at either of the internal surface side and the external surface side. This causes an uniform inflation of the container 1 in wide thickness and permits the production of a synthetic resin product having a uniform thickness.
