Flame mitigation device (FMD) for use with a portable fuel container

A device for mitigating fuel vapor ignition within a fuel container comprising:

• a body having a length, an interior sidewall and exterior sidewall;
• a generally annular rim configured at an upper end of the body;
• a bottom at a lower end of the body, the body's length being substantially equal to the distance between the upper and lower ends of the body;
• an indented fuel flow member projecting inwardly from the interior sidewall of the body;
• wherein the body and bottom both include a plurality of substantially rectangular holes;
• and
• a plurality of stepped ribs, each stepped rib extending inwardly from the interior sidewall toward a center of the body, wherein first and second stepped ribs are configured to substantially center a fuel nozzle in the body.

A flame mitigation device (FMD) for controlling fuel flow into a fuel reservoir comprising:

• a body having an interior sidewall and exterior sidewall;
• a generally annular rim at an upper end of the body and which is configured to hold the body in a fuel reservoir;
• and
• a bottom at a lower end of the body;
• and
• an indented fuel flow member extending inwardly from the interior sidewall of the body;
• stepped ribs extending inwardly from the interior sidewall of the body, the stepped ribs being configured to position the center of a fuel nozzle at substantially the center of the body when the fuel nozzle is inserted a predetermined distance into the body.

A flame mitigation device (FMD) for use within a portable fuel container comprising:

• a generally cylindrical body having a sidewall, the sidewall having an interior sidewall surface and exterior sidewall surface, the generally cylindrical body also having a length;
• an annular rim at an upper end of the body;
• a bottom at a lower end of the body;
• wherein the length of the generally cylindrical body is substantially the same as the distance between the upper and lower ends of the body;
• an indented fuel flow member extending inwardly from the interior sidewall surface of the generally cylindrical body, the indented fuel flow member having a length that is substantially the same as the length of the generally cylindrical body, the indented fuel flow member being configured to reduce cyclonic flow in the body;
• and a plurality of stepped ribs extending inwardly within the interior sidewall, the stepped ribs being configured to align the center of a fuel nozzle with the center of the FMD and additionally configured to reduce fuel splash from fuel flowing from a nozzle inserted into the body.
