Inflatable bag

An inflatable bag comprising:

• a collapsible air-tight bag body;
• a collapsible air inlet device sealed to said collapsible air-tight bag body through which forced air is driven into said air-tight bag body, said collapsible air inlet device being two rectangular flaps sealed together along their longitudinal edges to form a tubular structure having open ends and an inside wall area coated with a layer of ink for preventing portions forming the inside wall area from being sealed together and ensuring free air flow through the tube;
• a blow pipe securely fastened to said collapsible air inlet device, said blow pipe having an inner end inserted into the ink-coated inside wall area of said air inlet device and an outer end extended out of said collapsible air-tight bag;
• engagement means formed integrally with the periphery of said blow pipe outside of said collapsible air-tight bag body adjacent to said collapsible air inlet device;
• a support member engaged with the engagement means and positioned for supporting the air-tight bag body on the blow pipe;
• a tubular stick fastened to said blow pipe outside said collapsible air-tight bag body, the stick being secured at one end of said support member;
• and
• wherein said collapsible air inlet device is compressible by air pressure to close the ink-coated inside wall area of said collapsible air inlet device and to prevent air from escaping out of said collapsible air-tight bag body after said collapsible air-tight bag body has been inflated by air that has been forced through said blow pipe and said collapsible air inlet device into said collapsible air-tight bag body.
