Who invented the bottle cap for drinks?
This is a reusable rubber plug with an outer annular frame. Soon, he designed the world's first disposable cork stopper made of non-cork. That's a rubber block in a bottle neck. The pressure in the bottle keeps the rubber sheet protruding in the middle sealed. A layer of wax cloth makes the drink in the bottle tasteless, and there is a pull ring on the rubber sheet to open the cork. This kind of disposable bottle stopper is very popular with consumers, but Pinter is still thinking of a better idea. 1892, Pinter applied for a patent for bottle stopper. The scheme is to stick a cork on a metal sheet, which can be wrinkled and fixed on the bottle mouth. This crumpled metal piece looks like a small crown, so Pinter calls it a "crown bottle cap". So how do you take the "crown bottle cap" off the bottle? Pinter's original design is to open two small holes in the metal sheet, into which a bottle opener can be inserted to open the bottle cap. He also tried to open the bottle cap with a pull ring, just like the pull ring on a rubber bottle stopper. However, both of these methods need to increase the production process and need thick cork pieces to prevent air leakage. Finally, Pinter realized that if the metal sheet was bigger, the cork layer could be thinner, and he pried it open from below with a bottle opener. This is the bottle cap we saw today. "Crown bottle cap" is cheaper and more reliable than any bottle cap on the market at that time, and it also allows some differences and changes in the diameter of each bottle mouth, and even the bottle cap can be used as a place to print trademarks. Pinter designed a pedal bottling and capping machine at 1893 in order to cooperate with "Crown Bottle Cap" to occupy the market. At the beginning of this century, he also designed an electric 8-head bottling machine, which can handle 60 ~ 100 bottles per minute. Pinter's invention of bottle caps and machines completely changed the beverage packaging industry. By 1909, when Pinter's patent protection for bottle caps expired, the "Crown Bottle Cap" had entered its heyday, and all major beverage bottling plants in Europe and America adopted the "Crown Bottle Cap". This kind of bottle cap has always monopolized the market, and it was not until the 1960s that the screw cap appeared to "compete" with it.
