They are underappreciated, and it is easy to be forgotten somewhere ... But if it doesn't exist, then no matter where we buy drinks, we must finish drinking coffee in the store. Imagine you have to squeeze into the crowded Starbucks to enjoy your drink in a crowded space. We would say: No, thank you.
The forefront of the history of disposable coffee cups began in the early 20th century. In the past, whether people were drinking or drinking from fountains, buckets, wells, and trucks scattered around the city, yes, a public cup ... everyone shared. After the Spanish flu outbreak in 1918, people started using disposable cups. Since then, disposable cups have taken root in culture and stayed here.
Initially, disposable cups were limited to water, but later also used for hot drinks, such as coffee and tea. But no one wanted the cup to be hot. In 1933, Sydney Koons invented a handle attached to a paper cup, and then Walter Cecil invented a paper cup with a handle in 1936.
The 1960s was the golden age of disposable coffee cups. Four things happened at the time: the foam cup, the Anthora cup, and the peelable lid.
However, throughout the 1970s, innovation in disposable coffee cups seemed to have stalled, and the only development was the pull tab on the lid.
In the 1980s, there was a second round of innovation in disposable coffee cups. A traveler lid appeared, with a functional lid that leaves room for foam, protruding edges help to cool the coffee before it reaches the mouth of the drinker, and even a small inclination in the middle prevents the drinker from breaking the nose Lean against plastic.
By the 1990s, people were worried about their safety when they started drinking coffee. The disadvantage of a disposable cup is obvious-it is not insulated. This problem was quickly solved, and Jary Sorenson invented the cardboard sleeve in 1991. At the same time, paper cup manufacturers have developed double- and triple-walled cups, which have helped improve insulation.
Recently, Think Coffee and KeepCup in Australia have encouraged the use of reusable cups. But the convenience that disposable coffee cups bring to us is irreplaceable.
