Before filling the water, the air in the bag should be exhausted (the bag should be flattened and squeezed from the back to the front), so as to prevent the air in the bag from being heated and swelled and spraying the boiling water and hurting people.

Before use, it should be tested with boiling water, and the surface should be checked for scratches, leakage, cracks and aging. If any of them is found, refuse to use it. Before use, check whether the plug has a gasket and whether the gasket is damaged.
