ある。The present invention provides a transparent saturated polyester resin machine formed thinly by biaxial stretching, in which a protruding portion is provided at the lower end of the bottle body and a peripheral edge portion of the bottom of the bottle is bent downward. It has legs formed by It is possible to achieve the effect that the bottom part does not undergo crazing or thermal deformation even when containing contents containing alcohol-based components such as the following.

変形を生じやすい状態となっている。The present invention will be described in detail below based on the drawings. As shown in FIG. A leg portion 6 is formed by the protruding portion 5 . The bottom part 4 has a characteristic of biaxial stretch blow molding, and the degree of stretching is smaller as it gets closer to the center of the bottom part than the leg part 6, and therefore, compared to the leg part 6, it is less likely to be stretched than the leg part 6. It has poor resistance to contents containing ingredients, and is prone to clay songs and thermal deformation.

体を熱処理による結晶化の白化部（点線で示す部分〕と
したものである。Therefore, in the fish body of the present invention, the entire bottom portion 4 except for the leg portions 6 is made into a whitened portion (the portion shown by the dotted line) due to crystallization due to heat treatment.

る。In order to form the polyester resin filling having the whitened portion, after injection molding a bottomed cylindrical transparent medium P having a full-sized mouth and neck as shown in FIG. 2, the intermediate material is The center part of the bottom of P, that is, the center part corresponding to the part that will become the bottom of the fish body when the intermediate rope material P is biaxially stretched and formed into a fish body, is heated to 0°C to 160°C using a heater or the like. °013 ~ 5 minutes 1? tT, and then slowly cooled to room temperature to cause whitening due to crystallization.
Next, the intermediate material P is biaxially stretched and blow molded to form a fish body with a whitened bottom except for the legs as shown in FIG.

ない程度に白化せしめることが必要である。Note that the glass transition temperature of saturated polyester resin is approximately 7.
If the temperature is 0°C and is heated for an appropriate period of time in a temperature range above this temperature and below the crystallization temperature and left to stand, crystallization occurs due to the correlation between temperature and time, resulting in a whitening phenomenon. Further, in the molding of the fish body, the intermediate material is biaxially stretched after whitening the bottom center portion, so it is necessary to whiten the material to an extent that the stretchability is not lost.

ない。Even if the bottom part of the fish body is not sufficiently stretched due to the characteristics of biaxial stretch blow molding, by making the bottom part a white part due to crystallization, the contents containing perfumes such as cologne, perfume, etc. and alcoholic components can be stored. Even when the bottle is stored, the bottom of the bottle will not form clay songs or undergo thermal deformation.
