Canned open after the vacuum can be saved is the difficulty of the tank is to restore the vacuum after the break, especially after the food is reduced, the liquid volume in the bottle will drop the situation through the self-heating device on the bottle, with the cap to increase One-way valve design to solve. Anyway, the cans are not required to the laboratory vacuum, the second closed the bottle, as long as the air in the bottle run out of a large part of the heat to room temperature, is the "quasi" vacuum state, but also can play the role of preservation The
