Bottle caps, or Closures, are used to seal the openings of bottles of many types. They can be small circular pieces of metal, usually steel, with plastic backings, and for plastic bottles a plastic cap is used instead. A bottle cap is typically colorfully decorated with the logo of the brand of beverage. Caps can also be plastic, sometimes with a pour spout. Flip-Top caps like Flapper closures provide controlled dispensing of dry products. Bottle caps are often made of a different type of plastic than the bottle itself, and are often recyclable. Bottle caps were originally designed to be pressed over and around the top of a glass bottle to grab a small flange on the bottleneck. The Crown Cork was patented by William Painter on 2 February 1892 (U.S. Patent 468,258). It originally had 24 teeth and a cork seal with a paper backing to prevent contact between the contents and the metal cap. The current version has 21 teeth. To open these bottles, a bottle opener is generally advised, although some bottles incorporate a screw cap, eliminating the need for the opener.
