The coffee cup lid once was taken to the court. In 1994, when hot liquid poured out of a coffee cup, causing a lady named Stella Lieberk to suffer third-degree burns, she took McDonald's to court. After the incident, McDonald's changed the design of the cup and printed the words "Caution", "Handle with care" and "This is a hot drink".
The oldest coffee lid design is a peel type. Peel back a part of the lid to drink the beverage in the cup. Among such cup lids, the one that has been retained so far is the peelable and fixed type, that is, the peeled part can be fixed on the lid. (Maybe it looks like the yogurt lid now.)
Lids that needs to be squeezed and pierced are rare. The drinker must pinch the two parts of the lid together and then poke a hole to let the coffee flow out. This prerequisite is not very attractive, after all, your dirty fingers are only a few cents away from the hot coffee. The most common type of cup lid today is the pucker type. You can drink coffee directly from the pre-punched holes in the lid. This is what Starbucks uses.
In the design of coffee cup lids, the pucker type lid is the most frequently innovative type. Many people's inspiration comes from the classic "Solo Traveler" design of Jack Clements in 1986: the outer ring of the cover is raised, and the inside is a grooved design, which is convenient for drinking and prevents your nose touches the lid of the cup.
In addition, there is a Viora cup lid full of architectural sense. The edge of the lid is raised high, imitating the shape of the mug, which helps the aroma of coffee exudes. The designer believes that smelling is one of the core elements of the drinking experience.
Other cup lid designs are quite entertaining. Some of them are molded into a face. One of the cup lids has too many dents on the face, that is, it has been pressed with countless small grooves, so that you can see the contents. It looks like acne on the lid. There is also a black cup lid with a triangular dent and a nose-shaped opening, reminiscent of the face of a black warrior.
