Premix and postmix (Wikipedia)

Premix and postmix are two methods of serving soft drinks—usually carbonated—that are alternatives to bottles and cans.

This premixed soft drink carbonation tester is constructed of tempered glass and stainless steel with a quick connect on the bottom, and a 100 psi gauge and a relief valve on the top. Used in the 1960s to check the pressure of premixed soft drinks before shipment in 5-gallon tanks, it is operated by connecting the tank to the quick connect, bleeding off gas to allow the glass to fill, then shaking it. The pressure is then read from the gauge.
