Abstract

PURPOSE:To obtain a bottle that can withstand the internal pressure after it has been filled with the contents and also withstand heating when sterilization is carried out, by cooling the outer periopheral part of the bottom part of a polyester resin bottle from the inside, which bottle is molded by biaxial stretch blow molding, while heating only the bottom part of the bottle so as to crystallize the bottom part. CONSTITUTION:A cylindrical member 5 toroidal in cross section is positioned in such a manner that the outer ring section 3 thereof is at an outer circumferential lower part 4 of the bottom part 2 of a polyester resin bottle 1 that is molded by biaxial stretch blow molding. Cooling water or cooling air is fed into the outer ring section 3 of the cylindrical member 5 to cool the outer periphery of the bottom part 2. Further, only the bottom part 2 is heated by means 7 for heating such as a far infrared heater, hot air heating, etc. from below the bottom part 2 through a central hollow section 6 of the cylindrical member 5 so as to crystallize the bottom part.

。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a molding method for filling a saturated polyester resin, which is suitable for filling drinks that are subject to internal pressure and require heat sterilization, such as fruit juice-containing carbonated drinks.

通常の飽和ポリエステル樹脂装填は果汁入り炭酸ガス含

まうものである。In the case of ordinary saturated polyester resin loading, when contents such as a fruit juice-containing carbonated beverage are filled, the bottom of the expander becomes deformed due to the internal pressure caused by the contents and the heating during heat sterilization.

したボトル成形方法がある。Therefore, in order to prevent the bottom from deforming, it has been considered to crystallize the bottom of the embankment body, but this can be done by crystallizing the intermediate layer of the parison gate part during injection molding, or by heating it with a heater etc. after molding the parison. There is a bottle forming method in which the bottom part is crystallized by biaxial stretching blowing.

のである。The present invention cools the outer periphery of the bottom of a polyester resin molded by biaxial stretch blow molding, and heats only the bottom using heating means from below the bottom to crystallize the contents. To provide a molding method for filling a polyester resin that can withstand internal pressure after filling and heat during heat sterilization, and prevents the bottom of the bottle from being deformed.

以下添付図面に基づいて本発明ポリエステル樹脂装填の
成形方法について説明する。The method for molding the polyester resin according to the present invention will be described below with reference to the accompanying drawings.

Cooling water or cooling air is fed into the outer ring portion 3 of the cylindrical member 5 to cool the outer periphery of the bottom portion 2. Furthermore, a far-infrared heater is installed from below the bottom part 2 through the central space 6 of the cylindrical member 5.
Alternatively, only the bottom portion 2 is heated by heating means 7 such as hot air heating to crystallize it.

上記のごとく、底部２の外側周縁を冷却せしめて底部２

できるものである。As mentioned above, the outer periphery of the bottom part 2 is cooled and the bottom part 2 is cooled.
By heating, the heat caused by heating is not transmitted to the body, and only the bottom can be crystallized reliably and quickly.

Compared to ordinary saturated polyester resin packaging machines, this method is particularly effective as a method for molding a saturated polyester resin packaging machine in which almost no deformation of the embankment occurs.
