(I used to believe that the old term "codswallop" was derived from those bottles as you'd give them a wallop to dislodge the marble. However, it looks like Hancock's Half-Hour from 1959 is the first recorded usage of it which wouldn't fit with the usage of Codd bottles)

They are a nightmare to open if you lose the cap though
