In 1872, he patented a bottle filled under gas pressure which pushed a marble against a rubber washer in the neck, creating a seal for soft drinks.

Letters patent issued to him in November 1870 stated that he was a soda water manufacturer living at 6 Park Place, Islington.

In 1872 he was introduced to Richard Barrett, of London, whose two sons owned the Malvern Mineral Water Co. at Grove Lane, Camberwell.

Codd had two factories in London solely producing marbles, one in Kennington and the other in Camberwell, which was run by F. Barrett, the son of his financial backer.

His Malvern Mineral Water Works and both marble producing factories continued to thrive and he was still involved with Frederick Foster and William Brooke, his early backers.

On 6 October 1884, Codd allowed his partner to buy him out of the business and started trading at 41 Gracechurch Street, London.

In February of the same year, his wife died aged 54; they had four surviving children: Ada Louisa, Maud M, Edith J, and Alfred Charles.

Codd-neck bottles are also mass-produced for the popular Japanese soft drink, Ramune, which is produced in a wide variety of flavours by Shirakiku.
