Codd-neck bottles.

A Codd-neck bottle is a type of bottle used for carbonated drinks.

Description

In 1872, British soft drink maker Hiram Codd of Camberwell, London, designed and patented a bottle designed specifically for carbonated drinks.

The Codd-neck bottle was designed and manufactured to enclose a marble and a rubber washer/gasket in the neck.

The bottles are filled upside down, and pressure of the gas in the bottle forced the marble against the washer, sealing in the carbonation.

The bottle was pinched into a special shape to provide a chamber into which the marble was pushed to open the bottle. This prevented the marble from blocking the neck as the drink was poured.
