PepsiCo introduced the first two-liter sized soft drink bottle in 1970. [1] Motivated by market research conducted by new marketing vice president John Sculley (who would later be known for heading Apple Inc. from 1983 to 1993), [2] the bottle and the method of its production were designed by a team led by Nathaniel Wyeth of DuPont, who received the patent in 1973.

Sodas are carbonated up to 5 volumes of CO 2, which requires a pressure of 38.9 pounds per square inch (2.68 bar) at a serving temperature of 40 °F (4 °C). Beers are carbonated from 1.5 to 4.5 volumes of CO 2 , depending on the style; typical pressures are around 10–20 psi (0.69–1.38 bar).
A Fizz-Keeper is a type of closure that is marketed as a way to keep carbonation in soft drinks. It consists of a small round hand pump that is screwed onto the top of a plastic soft drink bottle, which is then used to pump air into the bottle, preventing the drink from going flat. [1][2][3][4] Research into the Fizz-Keeper's mechanisms and ...
Experimental measurements suggest that as many as 14 million bubbles are produced per liter of soda in this experiment. [20] Carbonated sodas contain elevated levels of carbon dioxide under pressure. The solution becomes supersaturated with carbon dioxide when the bottle is opened, and the pressure is released. Under these conditions, carbon ...
About a month before the planned release date, a photo was posted on a Mountain Dew worker's Pongr, which showed Pitch Black and 2008's Supernova. Two weeks before the release, Dew Labs announced the return of 2010's Typhoon in 2-liter bottles exclusively at Walmart Supercenters. The three flavors were re-released to stores on 2 May.
Followed up on in 2015 with Pepsi Strong and Pepsi Strong Zero. These were sold in larger sizes and with an even higher concentration of caffeine and carbonation. [24] This was further followed up on in May 2016 with Pepsi Strong 5.0 GV, a soda so carbonated that a new bottle had to be designed to contain it. [25] Pepsi Mont Blanc 2010
Soda siphons. As early as 1790, the concept of an "aerosol" was introduced in France, with self-pressurized carbonated beverages. [1] The modern siphon was created in 1829, when two Frenchmen patented a hollow corkscrew which could be inserted into a soda bottle and, by use of a valve, allowed a portion of the contents to be dispensed while maintaining the pressure on the inside of the bottle ...
The bottles were filled upside down, and pressure of the gas in the bottle forced the marble against the washer, sealing in the carbonation. The bottle was pinched into a special shape to provide a chamber into which the marble was pushed to open the bottle. This prevented the marble from blocking the neck as the drink was poured. [20] R.
