摘要： A blow molding machine is subjected to a sterilizing treatment in a simple manner. A liquid sterilizer is filled into preforms of at least the same number as the number of spindles. In a heating unit that heats the preforms to a molding temperature, some of the liquid sterilizer is caused to diffuse, and blow air is blasted into preforms in which the liquid sterilizer remains to cause the liquid sterilizer to diffuse in a molding unit, and molded bottles are discharged.

摘要： A step of letting a preform made of resin adsorb a sterilizer, a step of sterilizing the preform by heating the preform having adsorbed the sterilizer to a temperature suitable for a blow-molding treatment to activate the sterilizer adsorbed by the preform and a step of shaping the preform into a bottle by blowing aseptic air into the preform in a mold are performed sequentially. According to the above-mentioned steps, the sterilizer does not enter a blow-molding machine.

摘要： A preform is sterilized by a preform sterilizer. The preform is blow-molded by a blow-molding device to manufacture a container. Next, the container is filled with a culture medium by a filling device without sterilizing the container by a container sterilizer, and the container is plugged by a plugging device. Thereafter, it is verified how much microorganism survive or propagate in the culture medium in the container. A degree of sterilization in the container sterilizer is adjusted on the basis of a verification result.

摘要： A content filling system includes a filling device which fills content L in a container which includes a mouth and a container main body. A bubble detecting device is arranged on a downstream side of the filling device, and automatically detects whether or not there are bubbles produced in the content L filled in the container and discharged from the mouth of the container. A determining unit specifies the container which has discharged the bubbles.

摘要： To facilitate removal of foreign matters from a preform. The preform in an inverted position with a mouth portion thereof facing down is being continuously transferred, filtered air is blasted into the preform through the mouth portion of the preform, and at the same time, air is sucked from the side of the mouth portion of the preform. Foreign matters can be more easily discharged from the preform because of the flow of air and the weight of the foreign matters.

摘要： A cap sterilizer (50) includes an infeed chamber (52), a sterilant atomizing chamber (53), and an air rinse chamber (54). At least the infeed chamber (52) and the air rinse chamber (54) are exhausted. Both an exhaust pressure (E2) in the infeed chamber (52) and an exhaust pressure (E4) in the air rinse chamber are higher than an exhaust pressure (E3) in the sterilant atomizing chamber (53), or the sterilant atomizing chamber (53) is not exhausted.

摘要： Only a bottle properly preliminarily heated is sterilized by hydrogen peroxide. Temperature inspection to the bottle is performed while travelling the bottle. During the inspection, a bottle of which temperature does not reach a predetermined temperature is removed and a bottle of which temperature reaches the predetermined temperature is continuously traveled, hydrogen peroxide condensed mist α is blown toward a mouth portion 1a of the bottle by a spray tube 59 disposed at a predetermined position, and hot air is blown into the bottle from the nozzle while the nozzle 64 following the mouth portion of the bottle. According to such operation, only the bottle properly heated can be sterilized by the hydrogen peroxide, Thereafter, beverage fills the bottle, which is then sealed.
