Informação Básica

Descrição: These metal beer bottle tops are crimped onto the head of the glass bottle (usually with 21 crimps). Today they have a plastic insert to assist in getting a waterproof seal, earlier it was often made of cork. Known as "crown cork/seal/cap" bottle tops, they were patented in 1892 by William Painter in Baltimore, USA. Today they are found worldwide being used for non-alcoholic and alcoholic beverages sold in glass bottles. If they are thrown away into the wider environment, the metal and plastic can separate. Slowly, the protective coating (paint or metal coated) degrades and the steel inner core starts rusting, releasing ferrous minerals back into the environment. The plastic inserts do not easily degrade.

Usos Históricos

Patented in 1892 by William Painter in Baltimore, Crown Holdings has been manufacturing these pressed, crimpted metal bottle tops for 130 years. Originally the liquid seal inside the metal cap was made of cork but was replaced by synthetic plastics since the 1960s onwards. This type of top is used on drinks containing fermentation gases or carbon dioxide i.e. it can take a certain amount of gas pressure from inside the bottle but still remain intact.

Usos Presentes

Same as the historical uses i.e. for sodas, beers and carbonated drinks where the top needs to maintain the dissolved gas inside the liquid in the bottle.

Impacto Presente

Where people gather for music festivals, sporting events or the beach in summer, it is possible to find these crown tops in large numbers if recycling facilities are absent.
