Flammable Liquid Plunger Can

A cylindrical metal container designed to dispense hazardous liquids through a center mounted plunger. It is used primarily for moistening cleaning rags, sponges, swabs and the like. In operation, a sponge or swab may be saturated by placing it over a screened circular tray which is mounted on the top of the plunger and exerting a downward pressure, forcing the liquid upward. The plunger automatically returns to an extended position by means of a compression spring, when pressure is released. See also can, bench, flammable liquid. For items intended for temporary storage or handling of flammable liquids, see safety can.
