A cup of take-out coffee is the start of many people's mornings. The fragrant coffee carried on the road is always the temptation on the way, making you want to take a sip. However, some coffee cup lids design is that once they are opened, they cannot be closed again. After a light taste, the coffee is easy to overflow with the steps or the vibration of the carriage, or even splash on the body. The small coffee cup lid, which has been continuously improved since its introduction, is only to solve this problem: to prevent coffee from spilling on the road.
Trace the invention of the coffee cup lid back to 1953, with a peel-off lid designed by Delbert E. Phinney, which was then patented. The so-called "peel-off" lid, in which a small piece of film is torn from the scribed position to drink coffee, is still common today. The "pinch-down" design is similar to peeling, the difference is that when opening, you need to use the pressure of the thumb and index finger to buckle the cover instead of tearing it off completely. "Poke through" is to press the raised button down, and when the button is recessed, cracks will occur, keeping the cover intact and avoiding accidental tearing of the cup cover when pulling.
However, the design of the removable lid was flawed, and it was even more evident in the 1980s when to-go coffee was very popular. People have become so impatient that they can't wait to reach their destination and can't wait to take a sip on the road. If the cover is removed, it is equivalent to opening the gap that cannot be blocked, and the liquid can be spilled at any time. At the same time, the design of the snap-through lid sometimes allows fingers to directly touch the hot coffee in the cup.
The new environmental protection is the source of the designer's innovative power. To this end, different forms of cup lids have begun to appear, and the most diverse innovation among them is the "mouth pursing" design. The user drinks the coffee directly from the raised mouth of the lid, so the lips will not touch the surface of the cup, which looks like a pursed mouth. The outer edge of the lid is protruded, and the inner grooves allow enough space for coffee even if it overflows.
In recent years, such coffee cup lids have been widely used. However, the innovation space does not shrink because of this. Disposable biodegradable coffee lids always have different requirements that need to be catered for. For example, adding a pressing point to mark the flavor on the cover is convenient for the brewer to cooperate with the buyer's choice. Entering the 21st century, foam coffee is so popular that some lids are raised to accommodate the foam. In addition, there are also many interesting designs, a Korean-designed lid, which protrudes into the shape of the nose and lips, allowing the drinker to have a close contact with the coffee while sipping.
After all, coffee is the protagonist, and people may not care much about the special coffee cup lid design. Behind this little thing, there is ingenuity and wisdom. Using them in teaching, it's important that people see coffee cup lids in a new way because it's magical in itself. The details of the lid are also overlooked, and their styles are not single.
