The bottle cap closes the bottle opening. A hat is usually decorated in colors with the logo of the beverage brand. Plastic hats are used for plastic bottles, while metals with plastic pads are used for glass; metal is usually made of steel. The plastic cap may have a cast spout. Flip-Top Close like Flapper closure provides controlled dry product expenditure. Hats for plastic bottles are often made of different types of plastic from bottles.

Jenis
The hat was originally designed to be pressed above and around the top of the glass bottle to pick up the small flanges in the jam.
Cork Crown
Cork crown patented by William Painter on February 2, 1892 (US Pat. 468,258). It has 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 commonly used.
The height of the crown cap is reduced and specified in the German DIN 6099 standard in the 1960s. It also defines a "twist-off" crown cap, now used in the United States, Canada, and Australia. The lid is pressed around the screw thread rather than the flanges, and can be removed by rotating the lid by hand, so there is no need to open.
Flip-top
The "flip-top" atau "swing-top" terdiri dari stopper plastik atau keramik yang diadakan di tempat oleh satu set kabel. Sebelum penemuan gabus mahkota, ini adalah metode yang dominan untuk menyegel botol yang mengandung cairan berkarbonasi.
Tipe lainnya
Tutup sekrup
The screw on the cover is the most common bottle cap. They are easy to apply by a variety of automatic equipment, or they can be applied by hand. However, the torsion closure application must be controlled so that the closure can function properly in the field. The closure should be applied tight enough to retain the seal and hold back-off closure, but should not be applied so closely that the end user can not remove the closure. They are often found on top of beer, such as Coors or Bud Light.
The screw cap is originally an internal screw design. A glass/bottle bottle with an internal screw thread just under the gasket seat, has a sloping chair, patented by Hyman (Himan) Frank from William Frank & Sons, Inc. from Pittsburgh, PA. He was awarded US patent 130208 A on August 6, 1872.

Layer material
Foamed Polyethylene (F217)
Usually used with plastic screw cap. The F-217 is a soft-topped polyethylene foam core with a solid and translucent polyethylene available in a thickness of 0.050 inches. F217 has become the industry standard because of its versatility, robustness, compressed seal, cleanliness (no pulp dust) and economy. F217 liners have excellent chemical resistance and low humidity transmission rate. F217 has good taste and smell resistance.
Plastisol
Plastisol is a standard coating material used in metal closures for vacuum and bottle glass packaging. Plastisol is a flowing compound, usually a dispersion of PVC resins in plasticizers. It forms a solid, self-bonding gasket, sealing in closure. Plastisol liners are used in twist-off metal and continuous screw metal caps for use in hot-pack food products where vacuum preservation is essential.
Pressure-sensitive Liner (PS 22)
The styrene foam material is coated on the down side with a torque-driven adhesive. Pressure-sensitive internal seals attached to plastic or glass bottles with normal application torque. Pressure sensitive liners are supplied pressed to the closure and adhere to the bottle finish when closure is applied. The pressure sensitive liner is attached to the container because one side is coated with an adhesive bag. When closure is applied to the container, the adhesive bags break apart between the closing and completion of the bottle or bottle. Pressure-sensitive liners then stick to bottles or bottles and stay in place when closure is removed. No additional equipment required. Closure is provided with a standard liner as a backing. This material requires dry land on the bottle and is therefore only suitable for use with dry products such as vitamins, foods and medicines.
Pole conseal cone
Formed with Low Polyethylene Density, Polyseal cone layers are formed inside the bottle neck that provides a leak-proof seal that protects from die-casting and evaporation of the product. Very good for use with acid products and essential oils, this closure is recommended for use on glass bottles only.
Design without liner - crab's claw
A popular general purpose linerless sealer mechanism that can be used on almost any bottle. The design is usually equipped with a flange in.045 "formed when applied with normal application torque compressed to about half of its thickness when sealing the bottle lips.The coating creates a watertight seal with a bottle having a minimum.065" wide sealing surface free of nicks, burrs or deviation. This stylish linerless mechanism is available in popular spending caps.
Use of promotion
The Soda Company in particular uses hats for promotion. A message is printed on the inside of the hat and people with the right message can win prizes. Because bottles must be purchased to determine the message and win, people usually buy more drinks to increase their chances of winning. Some companies print interesting facts, puzzles or games inside the hats.
The long-term promotion by Coca-Cola is a MyCokeRewards program that started in 2006; most hats have alphanumeric code that can be inserted into their website in return for points.
In popular culture
One of the more prominent uses of conventional metal bottle caps in popular culture is its use in a series of video games Fallout . In post-apocalyptic America of the series, bottle caps - usually abbreviated only to "hats" - have been adopted by various peoples in the desert as de facto currency. Although the official currency is used by some of the more advanced factions, the hat is essentially a universal trading medium throughout the remnants of the country, to the extent that the discovery of bottle caps that serve threatens to destabilize the economy.
