Soda syphon
(重定向自Seltzer bottle)



The soda siphon (also spelled syphon), also known as the seltzer bottle or siphon seltzer bottle is a device for dispensing carbonated or soda water.
As early as 1790, the concept of an "aerosol" was introduced in France, with self-pressurized carbonated beverages. The modern syphon was created in 1829, when two French men 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 and preventing the remaining soda from going flat.
