A friend painted one of these and wondered what it was called. I thought it was a codswallop bottle, but looked it up and codswallop is a word for nonsense, for instance used in a phrase ‘a load of codswallop’ meaning a load of rubbish, or inaccurate, or something that isn’t true?
Then when I looked up codswallop bottle it came up with this: ‘A Codd-neck bottle is a type of bottle used for carbonated drinks. It has a closing design based on a glass marble which is held against a rubber seal, which sits within a recess in the lip. Wikipedia‘.
Thinking about it, could this be a cleaner, greener method of closing a bottle? I think it’s an interesting design. I think it’s Victorian?
