This small metal instrument, often uniquely shaped for a specific vending apparatus, grants access to the internal mechanisms of dispensers containing brightly colored chewing gum. Typically, it unlocks a compartment allowing for the replenishment of gum, collection of coins, or maintenance of the machine. An example would be the type used for a vintage, cast-iron gumball dispenser.
Controlling access to the contents and revenue within, these instruments represent a crucial element in the operation and security of bulk vending devices. Their design often reflects the era of the machine itself, offering a tangible connection to the history of vending technology. Possession signifies responsibility for the machine’s upkeep and profitability, a role historically filled by shop owners or dedicated vendors.
