When this sink occurs, the appearance of the rectangular plastic bottle is impaired, the commercial value of the product is reduced, and the strength of the product is reduced. As shown in FIG. 3, the sink 122 is formed by sticking the bottle to the mold 123 at the time of molding and thereby pulling the corner surface, which is the diagonal surface of the bottle, when the mold is released (during opening). This sink is more likely to occur as the mold temperature is higher, and is more likely to occur as the mold opening speed is higher. Also, the frequency of occurrence of sink marks varies depending on the location of the square plastic bottle. For example, even when the temperature of the diagonal surface is increased, 2% at the top of the bell, 45% at the shoulder, 42% at the upper waist, and 42% at the waist. 4 at the bottom
