<p>A deaerating method and deaerating apparatus in a bag-filling packaging machine, using a pair of press-holding members 1, 2 with one of them having a main body 3 and a slide element 4 that fits in the main body. A vacuum passage 6 is formed between the upper portion of the slide element and the main body, and a groove 9 is formed on a press-holding surface side 3a when the slide element is moved backward; and with this groove, a passage leading from the inside to the outside of a bag W 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 6. When the slide element 4 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 6. <IMAGE></p> |
