Flash suppressor for inhibiting explosions

A flash suppressor for use in an opening of a fuel container, the flash suppressor comprising:

• an annular rim;
• a bottom wall;
• and
• a sidewall extending downwardly from the annular rim to the bottom wall, wherein the sidewall defines a plurality of perforations;
• wherein:
• the flash suppressor is at least 10 percent open and not more than 80 percent open;
• the flash suppressor is configured such that, when the flash suppressor is positioned proximate to the opening of the fuel container and a liquid fuel is dispensed from the container through the plurality of perforations and the opening and the flash suppressor is no longer submerged in the liquid fuel, a quantity of the liquid fuel is retained by the plurality of perforations, the quantity of the liquid fuel being sufficient to provide a fuel-air mixture proximate to the opening of the fuel container that is too rich to support combustion within the flash suppressor;
• and
• the flash suppressor consists essentially of an injection molded synthetic resin material.
