Coffee cup

A coffee cup is a container that coffee and espresso-based drinks are served in. Coffee cups are typically made of glazed ceramic, and have a single handle for portability while the beverage is hot. Ceramic construction allows a beverage to be drunk while hot, providing insulation to the beverage, and quickly washed with cold water without fear of breakage, compared to typical glassware.

A coffee cup may also be a disposable cup in which hot beverages, including coffee, can be contained. Disposable coffee cups may be made out of paper or styrofoam. At coffee shops, paper cups are commonly used to give beverages to customers on the go, usually with a coffee cup sleeve to provide insulation against heat transferred through the container.

In the past, other materials which have been used to make coffee cups are clay, wood, strengthened glass, metal, ceramic and porcelain.

Usually made of plastic, the first patent for a coffee cup lid design was filed in 1967, and focused on creating a tight seal between the cup and the lid to reduce leaking and a vent hole to allow steam to escape. However, there was no opening for drinking, and the consumer would have to tear into the lid. In 1986, the Solo Traveler lid was created; it is found in the Museum of Modern Art’s 2004 exhibit "Humble Masterpieces.". Recent lid designs like the Viora have improved on Solo Traveler's design, which has too small a vent to allow sufficient air to enter while drinking. Louise Harpman, owner of the world’s largest collection of coffee cup lids, suggests that coffee cup lids “represent a major shift in American ‘to-go’ culture.”
