Pump-less inflation device and inflation method using consecutive chemical reactions
First Claim
1. A pump-less inflation device, comprising:
- a hollow conical casing with a narrow first end that is connected to an inflation pin and a wide second end;
a puncturable membrane that covers and seals the wide second end;
a one-way valve located proximal to the narrow first end, that prevents gas ingress into the inflation device, and allows gas egress from the hollow interior through the inflation pin at the narrow first end when a pressure threshold is reached;
a first chemical that reacts with oxygen and generates heat; and
a second chemical that decomposes when heated and releases nitrogen gas;
wherein the puncturable membrane and the one-way valve together seal the hollow conical casing,and wherein puncturing the puncturable membrane allows atmospheric oxygen to enter the inflation device and react with the first chemical, which generates heat and decomposes the second chemical, which releases nitrogen gas that escapes from the narrow first end of the inflation device.

Abstract
A pump-less inflation device including a hollow conical casing, a puncturable membrane, a one-way valve that allows gas egress from the casing, a first chemical that reacts with oxygen and generates heat, and a second chemical that decomposes when heated and releases nitrogen gas. A method of inflating an inflatable object using the inflation device whereby the puncturable membrane is punctured with a puncturing device to allow oxygen to enter the inflation device and react with the first chemical, which generates heat and decomposes the second chemical, which releases nitrogen gas that escapes from the narrow first end of the inflation device. The inflatable object is inflated with the released nitrogen gas.
