Abstract
A new composition, method, and apparatus for sealing and inflating a flat tire are described. The new composition includes a gas-generating agent and an activator, along with a sealant. In use, a gas propellant is generated in situ when the gas-generating agent is mixed with the activator. For example, carbon dioxide is generated when carbonates, such as baking soda, and an acid are mixed. The carbon dioxide gas generated in this manner can inflate a flat tire to a desired pressure. In addition to carbon dioxide, nitrogen gas, noble gases, and nitrous oxide gas may also be used instead.
Claims13
A tire sealing and inflating composition, comprising:
- a sealant;
- a gas-generating agent not in the gaseous state and capable of releasing carbon dioxides;
- and
- an activator compound separated from the gas-generating agent before use, the activator compound capable of generating a gas in situ to propel the sealant when contacted with the gas-generating agent, wherein the activator compound is sodium hydrogen sulfate.
