Plunger cans safely store, transport and dispense flammable or volatile liquids. They increase safety when using moistening cloths and wipes with hazardous materials for cleaning or other uses. Plunger cans eliminate the possibility of dangerous and messy spills.
Manufacturers generally make plunger cans with materials like galvanized steel, which is resistant to dents, rust and certain chemicals. A dasher plate mounted on a spring pushes down to dispense small amounts of the stored liquid, with excess liquid flowing back into the container. It also includes a flame barrier. Brass pump assemblies are common on plunger cans, as are molded protectors along the top rims of the cans.
