Abstract

An inflatable bag includes a collapsible air-tight bag body and a collapsible air inlet device sealed to the collapsible air-tight bag body. The collapsible air inlet device being a flat tube formed of two rectangular flaps sealed together and having an inside wall coated with a layer of ink. And a blow pipe has an inner end inserted into the ink-coated inside wall inside the air inlet device and peripherally sealed to the collapsible air inlet device and an outer end extended out of the collapsible air-tight bag. Forced air is blown through the blow pipe into the air inlet device stretches open the air inlet device and inflates the air-tight bag body, and the air inlet device is compressed by air pressure to close its ink-coated inside wall to stop air from escaping out of the air-tight bag body after the air-tight bag body has been inflated.

Claims

1. 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.
