くする原因ともなっていた。By the way, as shown in FIG. 4, when the driving pin C is driven into the opening d of the parison b, the parison b that is in contact with the outer surface of the driving pin C moves downward during the driving process, and the opening d is moved downward. A thick portion, a so-called resin pool e, is formed at the lower end of portion d. If the hollow container is made of a highly transparent resin, the appearance will be impaired by the resin pool e, and furthermore, the resin pool e will bulge out at the boundary between the mouth part d and the body part f of the hollow container. This obstructs the flow of the contents when they are drained, and causes a large amount of the contents to remain inside the hollow container.

脂溜りが生じない。[Function] According to the blow molding method for a hollow container according to the present invention, after placing the parison between the split molds, a driving pin for regulating the inner diameter of the opening is driven into the parison from the upper or lower part of the split mold. However, since the driving pin has a part that regulates the inner diameter of the opening and a part that reduces in diameter in the driving direction, when driving the driving pin, a part of the parison must be moved to the part that reduces in diameter in the driving direction. However, by inflating the parison by blowing pressurized fluid into the parison, the moved parison is flattened. For this reason, a bulge in which the leading end side of the mouth portion in the driving direction of the driving pin is thick, that is, a so-called resin pool does not occur.

Since the pressurized fluid is injected into a deep area, in addition to flattening the parison due to the reduced diameter part of the driving pin as described above, the body is blown up so as to pull the boundary between the mouth and the mouth. Even if a resin pool temporarily forms at the boundary between the part and the body part, it will be eliminated and a flat surface will be formed.

。Moreover, since the pressurized fluid is blown into a deep part of the bariumen 14 from the tip of the blowing pin 12 which is extended long in the driving direction of the driving pin 9, the driving pin 9
0 In addition to the resin not moving due to the portion 11 whose diameter decreases in the driving direction, the body part l is blown so as to pull the boundary part with the mouth part 2, and the boundary part between the mouth part 2 and the body part l is temporarily inflated. Even if a resin pool occurs, it will be eliminated and a flat surface will be formed.

When driving the driving pin, a part of the parison is moved to the part whose diameter decreases in the driving direction, and pressurized fluid is blown into the parison from the driving tip through the driving pin to blow up the moved parison. The hollow container blow molding apparatus according to the present invention flattens the hollow container.
Blow molding involves placing a parison between split molds, then driving a driving pin into the parison from the top or bottom of the split mold to regulate the inner diameter of the mouth, and blowing pressurized fluid into the parison to form a hollow container. The driving pin has a part that regulates the inner diameter of the mouth which is smaller by the wall thickness of the mouth than the outer diameter regulating part of the mouth of the closed split mold, a part that reduces the diameter in the driving direction, and a part that reduces the diameter. It has a small-diameter blowing pin that extends further from the opening, and has a pressurized fluid blowing passage that leads to the tip of the blowing pin inside, so it is easy to drive the driving pin into the opening. However, in the process, there is no resin accumulation at the inner end of the mouth, and even if the hollow container is highly transparent, there is no resin accumulation that interferes with the appearance, giving it an excellent appearance.Moreover, there is no resin accumulation. Therefore, it is possible to obtain a plastic hollow container in which the outflow of the contents is not obstructed at all and the amount of residual contents is extremely small.
