Talk:Codd-neck bottle

why not use a regular cap
I'm probably missing something. What are the advantages of the marble patent over a regular cap that will hold the pressure?

My thoughts exactly....
But more so! What an inefficient way to bottle a beverage! First, you must make a marble, which I'm sure is more complex than pressing a simple steel cap. Second, you must carefully form the bottle so the marble falls into its receptacle, far more difficult than a simple bottle (and I cannot understand, even with the photos, how that even works!). Third, the complication of having to fill the bottles upside down. Only possible reasons I can come up with are that a.) this predates efficient bottling methods and corks don't work with pressurized drinks, and b.) it is a marketing ploy because they knew children would like the "free" marbles that came with a bottle, once you smashed it to get to it (a bonus! Who doesn't like to smash bottles!). Still love to know how that "receptacle" part works though...and how it prevents the marble from rolling down and sealing your drink as you tip it back to drain it.....45Colt 14:30, 15 January 2015 (UTC)
