  • Patent number: 4010914
    Abstract: Detonating primer cords for explosives are usually stored and dispensed from a reel sometimes contained in a cardboard box or the like. The present dispenser or container receives the reel upon a spindle and is mounted for free rotation upon a base support. The cord feeds through an aperture in the front wall of the container so that when the cord is pulled to dispense same, the container pivots upon the base so that the cord can be pulled out readily and easily. The dispenser is made of non-ferrous material to prevent electrical sparking from occuring thus adding to the safety of the dispenser.
