What is a device called that dispenses food after inserting money or tokens, without needing to be replenished after each use?

The device that dispenses food after inserting money or tokens without the need for replenishment after each use is commonly known as a vending machine. Vending machines are designed to provide a variety of food items or beverages to consumers in a convenient manner. They operate by allowing customers to select items through a simple interface, often using cash or electronic payments.

Vending machines are valuable in various settings, such as schools, workplaces, and public areas, as they ensure a continuous supply of snacks and drinks without needing constant supervision or restocking after each transaction. This allows for efficiency and convenience for both the vendor and the consumer, making them ideal for quick and accessible meals or snacks.

The other options do not accurately describe this type of device. A self-service item generally refers to items where customers serve themselves but does not imply the mechanism of payment or the automated dispensing feature. A standard menu item usually pertains to food on a menu in a restaurant setting rather than a payment-based dispensing machine. A nutrient vending machine, while it suggests a specialized function, is not a commonly used term and may lead to confusion regarding the general concept of a vending machine.
