what did the first vending machines in the early 1880's dispense
Vending machine A vending machine is an automated machine that provides items such as snacks, beverages, cigarettes and lottery tickets to consumers after money, a credit card, or specially designed card is inserted into the machine.[1] The first modern vending machines were developed in England in the early 1880s and dispensed postcards. Vending machines exist in many countries, and in more recent times, specialized vending machines that provide less common products compared to traditional vending machine items have been created and provided to consumers.
Diaper The first disposable diaper was invented in 1946 by Marion Donovan, a professional-turned-housewife who wanted to ensure her children's cloth diapers remained dry while they slept.[16] Donovan patented her design (called 'Boaters') in 1951. She also invented the first paper diapers, but executives did not invest in this idea and it was consequently scrapped for over ten years, until Procter & Gamble used Donovan's design ideas to create Pampers.
