ABSTRACT:
An apparatus for forming a hollow container from a hot closed-end parison includes injection molding a hot-closed-end parison, adjusting the temperature of the hot closed-end parison by heating or cooling the hot closed-end parison by heating in a predetermined location within a temperature adjusting pot in a temperature adjusting device. The parison is then blow-molded into a hollow container having a predetermined configuration after the parison has been adjusted in temperature. The temperature adjusting operation uses at least either of the temperature adjusting pot or a temperature adjusting core in the temperature adjusting device so as to apply a pre-treatment, such as by clamping, to a portion of the hot closed-end parison for obtaining the predetermined concavo-convex pattern in the hollow container formed at the subsequent blowing step. Thus, a hollow container, a portion of which has the desired concavo-convex pattern, can be mass-produced simply and inexpensively.
