The humble coffee lid doesn't get much attention unless you're spilling hot coffee on yourself. But those sipable to-go lids are more complicated than you might think. The coffee lid is like a strand of our cultural DNA. The coffee cup lid is an unassuming modern marvel hidden in plain sight.
Specht and Harpman trace the invention of the direct drinking cup lid in the United States to Delbert E. Phinney, who in 1953 patented his design of an insulated disposable cup and lid. Lift it up with your fingernail to create a drinking hole. However, the straight-drink lid design didn't catch on until a few decades later, when American drivers and other takeout customers tried to drink their hot drinks on the road, just as they already had iced drinks with straws. So they took the opaque, flat plastic cap that came with the hot coffee and ripped a hole in it to drink it. It worked, but it's not a convenient practice. As a result, inventors, designers and cup lid manufacturers started making lids designed for on-the-go drinking.
To look at the infinite variations of the humble coffee cup lid is to see human hopes and fears, desires and infinite ingenuity. It might seem a little overzealous, but the plastic takeaway coffee cup lids really went through many iterations to arrive at the deceptively simple raised lip design you'd drink Starbucks every day. In addition to improving the basic structure of the lid or the size of the hole, the designers also envisioned a completely different coffee drinking experience, such as a lid with a blister pack that you can open to release cream or sugar into the cup, with There are French presses that allow drinkers to brew and filter coffee on the go, and a lid with a sachet that can be filled with vanilla, cinnamon, hazelnut or other aromas to enhance the flavor experience.
The coffee lid manufacturer really wanted to make drinking hot beverages on the go the best experience possible. For example, in a 1976 patent for a straight-drink anti-shake closure for a drinking open-top container, inventor Stanley Ruff claimed that his lid improved on previous designs in seven unique ways, including sloshing reduction, nose adjustment And enhanced "mouth" and olfactory satisfaction, modern designers continue to innovate on the basic lid design, offering improvements large and small to address pet annoyances while providing a better drinking experience. The new lid design is designed to make drinking from the lid feel less like using a sippy cup and more like drinking directly from the rim of the cup, increasing the speed of liquid flow through the drinking hole, helping to cool the coffee and directing steam to the drinker Gives them more coffee aroma while drinking, among other functions.
