CONSTITUTION:A relation of a thickness (y) at each position excepting a bottle top stopper part to mean thickness (x) in a horizontal direction is as given in the formula. In polyethylene terephthalate resin used as raw material, intrinsic-viscosity [eta] (a value measured at 25 deg.C in O-chlorophenol) is generall 0.6-1.5dl/g and preferably 0.7-1.2l/g. Further, a melting point measured with a differential scanning calorimeter(DSC) is generally 210 deg.C-265 deg.C and preferably 220 deg.C-260 deg.C.

Abstract: PURPOSE:To reduce keeping cost or transport cost by subjecting a preform for forming a bottle composed of a synthetic resin to streching blow within a mold to mold the bottle and reducing the volume of the molded bottle within the mold so as to make the same smaller than that at the time of the filling of the bottle with content. CONSTITUTION:A preform 1 for forming a bottle composed of a synthetic resin is heated to stretching aptitude temp. and subjected to stretching blow within molds 9a, 9b having a plurality of gas introducing ports 11 to form a bottle 3. For example, the bottle 3 thus obtained is constituted of a non-flexible mouth part whose diameter is smaller than that of a body part, the body part having flexibility, a shoulder part having higher rigidity and larger wall thickness as compared with the body part and a bottom part. Subsequently, the volume of the bottle 3 is reduced within the molds 9a, 9b to produce a volume decreased bottle 10. For example, when the reduction ratio of,the inner volume of the bottle 10 is set to 50%, the bottle 10 can be kept or transported in quantity about twice that of the bottle 3 before decreased in volume.

Abstract: PURPOSE:To provide a bottle with an excellent heat resistance, for which the adsorption of a taste component or fragrance component, etc., is reduced by keeping the body part of the bottle under a mean crystallinity of a specified range for an oriented bottle made of polyester. CONSTITUTION:A pre-form is obtained by forming a copolymer polyester by an injection forming machine, and the pre-form is heated by an infrared ray heater in such a manner that the central surface temperature of the pre-form body 4 may become 115 deg., and orientation-blown by a forming machine, and thus, a bottle 1 is formed. In addition, this bottle is heat-set for not less than 3 seconds at a die temperature of 110-200 deg., and the mean crystallinity of the bottle body part 4 is made to be 32-70%. Then, the heat-set bottle 1 is cooled from the inside and outside, and taken out from the die. By this method, since the crystallinity of the bottle body part 4 is large, a bottle with an excellent non-adsorption property and heat resistance can be obtained.

Abstract: PURPOSE:To quickly remove an adsorbed material from a polyester bottle to enable the reuse of the bottle by keeping a polyester bottle having a bottle body part having a specific average crystallinity in an atmosphere of a specific temperature, thereby desorbing the material adsorbed on the bottle. CONSTITUTION:A polyester resin (e.g. polyethylene terephthalate) is molded by an injection molding machine. The formed preform is heated to the surface temperature of 90-100 deg.C at the middle of the preform body part and formed by a drawing blow molding with a molding machine to obtain a polyester bottle 1 having an average crystallinity of 32-70% at the body part 4 of the bottle. Methanol (or p-xylene) is poured into the bottle 1, left standing at 25 deg.C for 7 days and discharged from the bottle. The bottle is washed with distilled water of 20 deg.C and dried to effect the adsorption of methanol (or p-xylene) to the bottle and the bottle 1 is maintained in an atmosphere of 40-150 deg.C for 4hr to quickly desorb and remove the material adsorbed on the polyester bottle 1.

Abstract: PURPOSE:To provide resistance to stress crack and prevent the generation of cracks on the bottom because of the temperature, water content, a chemical and solvent by stretch blowing a saturated polyester preform, molding a bottle and then annealing the same. CONSTITUTION:A preform is formed by saturated polyester, and the heating temperature of saturated polyester at the time of molding the preform is desirably set in the range of 90-110 deg.C when the saturated polyester to be used is polyethylene terephthalate, and then the formed preform is heated up to the temperature fit for stretching, and stretch blown in a mold to form a bottle 1. Then, annealing is carried out. The annealing is desirably carried out for 12-48 hours at the temperature of 30-70 deg.C preferably under the state that the bottle 1 is unrestrained. The bottle thus manufactured is of superior resistance to stress crack.
