The stress calculation method and strength condition of PET aerated water bottle were obtained from theory. The strength of PET aerated water bottle was simulated and calculated ANSYS. The stress graphics of the bottle with different thickness was plotted and their stress property was analyzed. The influence of axial load and grooves on bottle stress was also studied.

The work electricity of Bottle Light needs no external power supply. Only one empty bottle (such as a cola bottle and a mineral water bottle) is needed. Screw down the original bottle cap and screw on Bottle light. Then compress the air in the bottle repeatedly to make the piston of Bottle Light move up and down, which changes mechanical energy into electric energy and light LED. Now a brand new light of environmental protection concept is in front of us.
