How Codd Bottles Work
The Inventor
A British soft drink maker named Hiram Codd invented this bottle. He lived in London, England. In 1872, he created and patented his special design. He wanted a better way to keep drinks fizzy.
Smart Design
Codd-neck bottles are made from thick glass. This helps them hold up against the pressure of the gas inside. Each bottle has a glass marble and a rubber washer in its neck.
Sealing the Fizz
To fill the bottle, it's turned upside down. The pressure from the gas inside pushes the marble against the rubber washer. This creates a tight seal. It locks all the fizz inside the drink.
Opening the Bottle
The bottle has a special pinched shape. This creates a small chamber. When you want to open the bottle, you push the marble into this chamber. This stops the marble from blocking the neck when you pour your drink. Some old Codd bottles looked like bullets. Many people enjoy collecting these antique bottles and their marbles.
Codd Bottle Popularity
A Global Hit
Soon after it was invented, the Codd-neck bottle became very popular. Soft drink and brewing companies loved it. It was used a lot in Europe, India, and Australia.
Why They Became Rare
These bottles were made for many years. But over time, their use slowly went down. Children often broke the bottles to get the glass marbles inside. Because of this, old Codd-neck bottles are quite rare today. They have become valuable collector items. For example, a blue Codd-neck bottle can sell for hundreds of British pounds at auctions!
Still Used Today
Even though they are rare, Codd-neck bottles are still used for some drinks. You can find them with the Japanese soft drink Ramune. They are also used for the Indian drink called Banta.
