Planted vacuum bottles that keep carbonated drinks sparkling
Vacuum insulated bottles that keep carbonated drinks from losing their fizz are now available to beer lovers who want something stronger when enjoying the great outdoors or just relaxing at home.
The trend has been sparked by a growing number of people now telecommuting from home due to the novel coronavirus pandemic or looking to escape the hubbub of city life for a while.
To earn to new customers, manufacturers are marketing products with well-arranged cap and bottle designs so that the carbon dioxide generated inside does not pose a safety risk.
Thermos KK started selling a vacuum bottle for cold carbonated drinks on March 1.
Its upper and screwed parts have a hole and a groove that allow the internal pressure to be released when the pressure inside becomes too high and when the cap is partially open. This ensures that the top will not fly off due to gas pressure and will prevent the bottle to break.
The cap must be removed after the initial unscrewing to release the internal pressure. FThe fluid in the stainless steel bottle is guaranteed to stay at a temperature of 10 degrees or less for six hours thanks to the vacuum insulated structure.
Thermos released its first canteen of soda in 2000, but sales were sluggish due to the widespread use of plastic bottles. The item was taken off the market in 2004.
But with the increase in popularity of sugar-free soft drinks among increasingly health-conscious consumers during the COVID-19 crisis, Thermos said it developed its latest product in response to demand to be able to “carry cold soft drinks”.
A Thermos representative said the company expects the product to appeal to a wider range of consumers.
“Reusable bottles are frequently used by women and children, but we hope demand will increase among men as well,” the official said.
A 0.5-liter bottle and its 0.75-liter counterpart carry price tags of 3,300 yen ($27) and 3,850 yen, respectively, including tax.
Tiger Corp., one of the nation’s leading manufacturers of thermos flasks and rice cookers, began selling a vacuum insulated carbonated beverage flask in January.
He designed a cap that allows carbon dioxide gas to be released when it rotates slowly. It is also equipped with a safety valve to automatically release the gas if the pressure inside increases.
The inside of the bottle has been specially treated to eliminate surface roughness to prevent the evaporation of carbonic acid.
The product is available in four types priced between 6,000 yen and 7,500 yen after tax. They vary in size from 0.5 liters to 1.5 liters. The largest is promoted as replace a pitcher of beer.
American company Hydro Flask leads the category with its Growler brand for soft drinks.
Alco International Co., an Osaka-based company that handles exclusive Hydro Flask sales in Japan, focused on displaying the product line at novelty stores and outdoor gear stores since 2016.
As craft beer is often sold by weight in the United States, a 1.9 liter vacuum bottle is now marketed with a retail price of 9,350 yen including tax.
Alco International said sales were increasing due to the growing popularity of camping and other outdoor activities that allow people to avoid crowded environments in the current health crisis.
