When this is done, the bottle is stretched and formed to have a smaller wall thickness, which weakens the strength, particularly the buckling strength. To solve this problem, it is necessary to provide reinforcement irregularities on the body of the bottle. Ta.

とが好ましい。A cylindrical parison with a bottom is made of PET resin using the injection molding method.
1) is molded to a predetermined size, and a temperature control rod (as shown in Figures 1 and 2) is attached to the parison (1) taken out from the injection molding machine.
2) and adjust the temperature of this parison (1). As shown in the cross-sectional view of FIG.
) is provided protrudingly, and the surface of the protruding strip (3) is set to be in contact with the inner surface of the parison (1) or located in the vicinity thereof, and this temperature control rod (2) When inserted into the parison (1), only the part facing the protrusion (3) is cooled, and the temperature is lower than that of the other parts. Here, when the part facing the protruding strip (3) is defined as a low temperature part (4) and the other part is defined as a high temperature part (5), the temperature adjustment is such that the mold temperature during blow molding, which will be described later, is 60 - If the temperature is 90°C, the high temperature part (5) of the parison (1) is 9O-12
0C is preferably adjusted to about 60-90C in the low temperature section (4).

成形する。The low temperature part (4) and the high temperature part (5) are now distributed in a vertical stripe shape, and the low temperature part (4) can be located anywhere, but generally it is located at a position where the parison (1) is equally divided. It is preferable to provide the In addition, when the cross-sectional shape of the body is an ellipse as shown in Fig. 3, it is preferable to arrange the corresponding mold (6) so that the cavity surface is within a certain range (χ). The parison (1) adjusted in this way is molded into a mold (6).
Insert the rond (

The curvature is constant so that the outer surface matches the inner surface, and the part that was the low temperature part (4) in the parison state has a thick wall part (11) because the elongation due to compressed air is small. ) and high temperature section (5)
A bottle 00) is obtained in which the thin wall portion α force forms a vertical stripe at a portion corresponding to .

) and the thick part (22), as shown in Figure 5, there is a part with a small curvature, and the synergistic effect ratio with the thick part results in reinforcement of that part. The hot parison method was explained in the explanation, but when using the cauldrison method, a pre-formed parison (preform) is heated to a predetermined temperature using a temperature control device, etc., and then a temperature control rod is used as in the above-mentioned real parison method. It may be inserted into a heated parison, partially adjusted to a low temperature section and a high temperature section, and stretch blow molded using the same method as in the above embodiment.
上記実施例では断面が客種円形の偏平ボトルを製造する

の製造方法である。<Effects> Since the present invention has the above-described configuration, the mold does not have a complicated shape with unevenness, and the molded bottle does not have a thick wall part like a vertical stripe or a curved part. By providing a small portion to increase strength, it is possible to manufacture bottles that can withstand lateral pressure, that is, prevention of denting of hot-filled bottles such as beverages, and buckling strength when capping. In addition, when pasting a label, unlike conventional methods, there is no unevenness formed on the outer surface, so it can be easily and neatly pasted after molding or at the same time as molding. This is an excellent method for producing plus bottles.
