Abstract
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.
