摘要

PURPOSE: To realize the mass production of a filling container equipped with refined external appearance intrinsic to the round mirror-shaped rice cake without material loss. ;CONSTITUTION: By utilizing an injection molding mold consisting of a mating pair or a cavity mold and a core 16b, a topped parison B is preliminarily injection-molded. In succession, under the condition that the topped parison B, which is under the state being covered on the core 16b, is still hot, the cavity mold is changed with a blow mold 2 consisting of a pair of split molds 21a and 21b so as to blast compressed air through the core 16b in the topped parison B in order to expand the parison. Thus, a filling container for offering a rice- cake, in which a small upper stage container and a large lower stage container are communicated with each other and, at the same time, a rice-cake inflowing port is opened at the center of the bottom face of the large container, is blow- molded.;COPYRIGHT: (C)1996,JPO
