There are many types of bottles caps; each will vary according to the manufacturer and the type of bottle used. Bottle caps are used to seal glass as well as plastic bottles containing soft drinks or alcoholic beverages.
External Threaded Cap
The external threaded cap was first patented in 1907; however, its earliest recorded use was in 1927. These caps are among the most commonly used bottle caps. They are generally made from plastic or aluminium and are screwed onto the top of a bottle.
The Kork-N-Seal first originated in 1911; the purpose of its design was to easily seal bottled products containing liquid. Kork-N-Seal caps are made of metal and have a loop that goes around the base. The loop is pulled up to remove the cap and pulled down to secure the contents of the bottle.
It is unknown when the first cork cap was invented; however different cork inventions were patented and have been recorded in many different countries including France, England and the U.S.A. This type of cap is typically used for wine bottles. It originates from the cork oak tree. The cork is elastic and slightly malleable; once it is pulled out of a bottle the cap reshapes itself and is able to be pushed back into the bottle for closure.
The lightening toggle was invented by a man named Charles de Quillfeldt. He patented the idea in New York on January 5, 1875. The lightening toggle is made of plastic attached to a rubber washer. A metal fixture is placed over the top and wrapped around the neck of the bottle. This type of cap is ideal for beer bottles as the pressure from the carbonation will not allow the cap to be pushed off.
