A filler body for introduction into a receptacle for a combustible liquid or gas, especially gasoline for hindering explosion-like combustion, comprising a ball having substantially a smooth outer surface and a large-pore internal structure composed of expanded metal.
A method of making a filler body for introduction into a receptacle adapted to contain a combustible liquid or gas to restrict explosion-like combustion therein, comprising the steps of:
- rolling an expanded metal strip into a substantially tubular cylindrical strand;
- severing said strand into respective hollow cylindrical pieces;
- and
- pressing said pieces into respective balls having substantially a smooth outer surface and a large-pore internal structure.
A method of preventing explosion-like combustion in a receptacle for a combustible liquid or gas which comprises the steps of:
- forming an expanded metal strip into a multiplicity of expanded metal balls having substantially a smooth outer surface and a large-pore internal structure;
- and
- substantially filling said receptacles with said balls.
