The Bottle Cap is a plastic closure used to cover the top opening of a bottle. It is often decorated with the brand's logo. This article will discuss some of the history of the bottle cap and the people who invented it. You'll also learn about the different types of plastic caps and their different uses.
The bottle cap was invented by Bertha Engele, a seamstress from Downstate Illinois. She was inspired to make something useful out of bottle caps when she saw a drugstore janitor throwing away a pail of them. She began making baskets, vases, and other things with them. Engele's creations were featured in Profitable Hobbies magazine, where she described the technique and showed a picture of an elaborate vase she made. The vase used more than 2,500 bottle caps.
Another bottle cap invention, the crown cap, was developed in 1892 and was inspired by the popularity of carbonated beverages. By the 1880s, carbonated drinks could be found in pubs and drugstores. At that time, bottle cap stoppers were usually cork, porcelain, or metal and came in contact with the liquid inside the bottle.
Crown Cork bottle cap invented by Painter
The Crown Cork bottle cap is an innovation that was invented by William Painter in 1892. It was a corrugated-flange bottle cap lined with a thin cork disc and backed with special paper. These characteristics of the cap made it a convenient and leak-proof closure. As the need for bottle caps increased, Painter began to develop the machinery needed to produce the caps. In 1892, he founded the Crown Cork and Seal Company, which would eventually be one of the world's leading manufacturers of cork products.
During his lifetime, Painter had accumulated more than 80 patents. The first crown caps were made of metal and filled with thin cork discs. Painter's invention was awarded U.S. patent number 468,258. His company, the Crown Cork and Seal Company, soon began mass producing the caps. By the 1930s, they had sold over half of the world's bottle caps.
Painter also invented the bottle opener and machine for crowning bottles. He also developed a device for detecting counterfeit currency. His innovations earned him a place in the National Inventors Hall of Fame in 2006.
A plastic bottle cap that is linerless is an improved version of a conventional plastic bottle cap. The linerless design is characterized by an inner flange that is typically 0.045" wide. This flange is pressed against the bottle's lip to form a watertight seal. This mechanism is particularly popular for dispensing bottles, as it is simpler and cheaper to manufacture.
The inner surface of a plastic bottle cap has a curved lower end, which provides a concave surface. This outer surface is relatively soft and conformable, whereas the adjacent curvilinear surface is relatively strong. The inner surface of a plastic bottle cap can also be concave or tapered.
