The United States invents new beer bottle liners that can be automatically deflated

The United States invented a new type of beer bottle liner, which is characterized by automatic deflation when the internal pressure of the beer bottle approaches the ultimate pressure that the bottle can withstand. This inner liner not only exhibits excellent sealing under medium pressure (about 5×105 PA), so as to ensure that the beer, which is extremely sensitive to the smell, does not occur due to environmental pollutants (such as O 2 ). The deterioration caused by infiltration will not affect the taste of beer due to the leakage of CO2 in the bottle, and from the perspective of food safety, the internal pressure of this new type of inner liner approaches the ultimate pressure that the bottle can withstand. The automatic deflating function (about 5×105 PA) avoids the danger of breaking and exploding the bottle caused by the beer being exposed to high temperature or sunlight for a long time and the high pressure automatically generated in the bottle.
