winkelwagens
Winkelwagens, or shopping carts, are wheeled containers used in supermarkets and other retail stores to carry goods during shopping. They typically consist of a metal or plastic frame with a basket, four swivel wheels, and a handle; many include a small seat for a child and a second lower shelf for additional items. Variants range from compact baskets to large trolleys designed for bulk shopping, and some models have plastic linings for easier cleaning. Stores may provide different cart sizes, and many use a coin or token deposit system to release carts from a corner or rail.
Operation and safety: Customers insert a coin or token to unlock a cart; the deposit is refunded
History and regional use: The concept of shopping carts originated in the United States in the 1930s
Impact: Winkelwagens increased shopping efficiency by allowing customers to collect multiple items and by speeding checkout
