    摘要： To effectively prevent occurrence of stretching unevenness during blow molding using a liquid as the pressure medium without significantly modifying the structure of a device, provided is a blow molding device including: a metal mold used for blow molding; and a blow nozzle that tightly communicates with a mouth tubular portion of a bottomed tubular preform, the liquid as the pressure medium being supplied into the preform through the blow nozzle. The blow nozzle is provided, at a lower end portion thereof, with an engaging tubular piece that is inserted into the mouth tubular portion, and the engaging tubular piece has a length by which a lower end of the engaging tubular piece extends further downward than a neck ring in a state where the blow nozzle is in communication with the mouth tubular portion, the neck ring being provided around a lower end of the mouth tubular portion.

    摘要： To prevent core misalignment when performs are stretched during blow molding, provided is a blow molding device that blow molds a preform into a container in a forming mold. The blow molding device includes a support pin that is disposed in the forming mold. The support pin includes a head that supports a bottom portion of the preform, and a shaft that is connected to the head and that is displaceable upward and downward in a direction of an axis of the preform. The head is provided, at one end thereof supporting the bottom portion of the preform, with a concave portion for receiving at least a part of the bottom portion.

    摘要： A slender synthetic resin heat-resistant bottle type container having a circumferential draw ratio of 2.8 or less, for example, comprises at least one pressure reduction absorbing panel (5) provided at a container body part, wherein the pressure reduction absorbing panel is provided with at least one convex portion (6) having a width larger at a lower side than at an upper side as viewed in a circumferential direction of the container. Alternatively, each pressure reduction absorbing panel has a border line bulged toward a container bottom part. This causes a resin to be smoothly stretched even at mold surface portions corresponding to concave and convex portions of a container body part surface upon blow molding. These avoid a defective appearance of the container and do not adversely affect heat resistance thereof.
