Abstract

PURPOSE:To preprint air leaks in one air chamber from influencing other air chambers, by keeping independently respective air chambers air-tight after blowing air into a plurality of air chambers in side a bag. CONSTITUTION:Sheets of film 1, 2 forming a bag are put on other sheets of film for valves 34 forming air pathes and check valves to define a plurality of air chambers 6 and air inlet path 7 by a lenear seal 5 like heat-sealing and also provide non-sealed portions 8 at respective air chamber portions of the lenear seal forming said air inlet path to make them air inlets to the air chambers. The air inlet path 7 is opened at an end to the outside of the bag, where air is blowed through the air inlet 9. Air flows into said respective air chambers via each non-sealed portion 8 from said air inlet path 7. Therefore, when respective air chambers 6 are filled with required air volume, tongues 10, 11 of the sheets of film for valves 3, 4 left in the air chambers at respective non-sealed portion 8 are closely pressed on stopping air blow to prevent air from back flowing by closing said non-sealed portions.
