Method for manufacturing plastic containers by blow molding
Disclosed is a method for forming blanks made from plastic material into containers, the method including steps of blowing into the blanks in such a way as to form them into containers, then internally degassing the formed containers. In the method, the steps are carried out according to a first cycle at a first rate. Then, during a second subsequent cycle of steps carried out at a second rate slower than the first rate, a time delay is added with respect to the first cycle, during or after degassing, such that the second cycle lasts longer than the first.

Liquid container manufacturing method
A liquid container manufacturing method of manufacturing a liquid container that contains a content liquid from a synthetic resin preform, the method including an inflation body insertion step of inserting an inflation body into the preform; an air discharge step of discharging air out of the preform by inflating an inflation body in the preform; a mouth blocking step of blocking a mouth of the preform; an inflation body contraction step of contracting the inflation body with the mouth blocked; and a liquid blow molding step of molding the preform into a liquid container by supplying a pressurized liquid into the preform through a blow nozzle.
Container sterilization method and container sterilization system
Provided is a novel container sterilization method in which no liquid agent is used. A container sterilization method is a method of performing sterilization by supplying a sterilization component to a container that is continuously conveyed along a predetermined conveyance path, the container sterilization method including supplying a humid ozone gas to a sterilization area, the humid ozone gas being an ozone gas that has humidity, the sterilization area being partitioned by a sterilization chamber that contains the conveyance path. The humidity of the humid ozone gas to be supplied to the sterilization region is regulated, depending on a temperature of the containers to be conveyed to the sterilization region.

Free blow bottle design
An apparatus and method for simultaneously forming and filling a plastic container without the use of a mold forming a mold cavity (116, 16) is provided. A pressure source (120, 20) includes an inlet (146, 150, 46, 50) and a piston-like device (140, 40). The piston-like device (140, 40) is moveable in a first direction wherein liquid is drawn into the pressure source (120, 20) through the inlet (146, 150, 46, 50) and in a second direction wherein the liquid is urged toward the preform (112, 12). A blow nozzle (122, 22) may be adapted to receive the liquid from the pressure source (120, 20) and transfer the liquid at high pressure (P2) into the preform (112, 12) thereby urging the preform (112, 12) to freely expand until an unopened end thereof contacts a platen (118). The platen (118) forms a bottom in a resultant container. The liquid remains within the container as an end product.
