Abstract

The invention discloses a production technique for a hot filling beverage bottle. The production technique comprises the following steps of (1) preparation of a bottle blank mold, (2) formation of a bottle blank, (3) shaping through heating, (4) forming, (5) detection and (6) packaging and delivery. The production technique has the beneficial effects that through design of the bottle blank mold, three retaining rings and six negative pressure blocks are designed on a bottle body, so that heat expansion and cold contraction generated in the filling process are offset, and the bottle is prevented from deforming; six concave-convex blocks are arranged at the bottle bottom, so that the bottle bottom protrude outwards when being heated in the filling process, and then the bottle cannot deform; and besides, through six sections of heating by a heating furnace and control over different temperatures of the bottle body, threads and the bottle bottom by a bottle blowing machine, the produced beverage bottle can resist high temperature of 85-90 DEG C, the bactericidal performance of filled juice beverages is greatly improved, and accordingly the beverages pass detection.

Description

technical field [0001] The invention belongs to the field of liquid storage and transportation, and in particular relates to a production process of a hot-fill beverage bottle. Background technique [0002] PET plastics, chemically called polyterephthalate plastics, mainly include polyethylene terephthalate (PET) and polybutylene terephthalate (PBT). The molecular structure is highly symmetrical and has a certain crystal orientation ability, so it has high film-forming properties. PET has good optical properties and weather resistance, and amorphous PET has good optical transparency. In addition, PET has excellent abrasion resistance, dimensional stability and electrical insulation. Bottles made of PET are widely used because of their high strength, good transparency, non-toxicity, impermeability, light weight, and high production efficiency. The molecular chain structure of PBT is similar to that of PET, and most of the properties are the same, except that the main chain...
