The blow molding device () is provided with a heating means () for heating a preform (P) to a temperature appropriate for molding, an antimicrobial agent-spraying means () for spraying an antimicrobial agent on the preform (P), a hot forming means for stretch blow molding the preform into a bottle (B), and an irradiation device () irradiating electromagnetic waves or ultrasonic waves on the bottle. After the heating means () has heated the preform (P), the anti-microbial agent-spraying means () sprays the anti-microbial agent and sterilizes the preform (P) with hot antimicrobial agent. During subsequent stretch blow molding of the preform (P), the hot forming means performs additional drying of antimicrobial agent retained on the preform (P) in the hot state and additional sterilization. The irradiation device () irradiates electromagnetic waves or ultrasonic waves to degrade the anti-microbial agent remaining on the molded bottle (B) and further promote antimicrobial agent drying and sterilization.

Blow molding device

A cleaning method is provided for on-site cleaning of equipment such as filling equipment that fills beverages, etc. into bottles, cans, and other containers, liquid treatment equipment for filling solutions, and pipe equipment for connecting said equipment, the method being able to increase significantly the cleanliness of portions in contact with the filling solution while shortening cleaning time and reducing the amount used of utilities such as cleaning solution, etc. In the cleaning method for on-site cleaning of the liquid pathways of equipment such as filling equipment () for filling beverages into bottles, cans and other containers, liquid-treatment equipment () for filling solutions, or pipe equipment () that connects said equipment, liquid comprising nanobubbles is pumped into said equipment and is left undisturbed to soak for a prescribed period.
