Vacuum bottles pitched that keep carbonated drinks fizzy in Japan

According to The Asahi Shimbun, vacuum-insulated bottles that keep carbonated drinks from losing their fizz are now being pitched to beer lovers who want something stronger when they are enjoying the great outdoors or simply chilling at home.
The trend was triggered by a growing number of people who now telework from home because of the novel coronavirus pandemic or seek to escape for a while from the hubbub of city life.
To win over new customers, manufacturers are marketing products with well-arranged cap and bottle designs so carbonic acid gas generated inside does not pose a safety risk.
