ABSTRACT:
A deaerating method and deaerating apparatus in a bag-filling packaging machine, using a pair of press-holding members with one of them having a main body and a slide element that fits in the main body. A vacuum passage is formed between the upper portion of the slide element and the main body, and a groove is formed on a press-holding surface side when the slide element is moved backward; and with this groove, a passage leading from the inside to the outside of a bag is formed. Air and excess liquid matter inside the bag are sucked out of the bag through the passage and are removed through the vacuum passage. When the slide element is moved forward and press-holds the portion of the mouth that corresponds to the passage, the liquid matter inside such portion is pushed and is removed through the vacuum passage.
