How to install an old-fashioned water bottle

The inner container of the water bottle protrudes from the bottom of the shell, and the base can be installed.

Turn the whole thermos upside down, then turn the bottom bracket counterclockwise, remove the inner container in the thermos, and take it out. After taking it out, remove the rubber pad at the spout of the new thermos bottle, then put the thermos bottle into the kettle body, unscrew the bottom bracket clockwise to complete the whole installation process, and it can be used normally.
