## Abstract

An environmentally friendly push-pull type non-circular cylindrical container includes a paper lid. A bottom side of the paper lid is fixedly installed with an inner tube that is fixedly sheathed with an elliptical tube. An inner wall of the elliptical tube is fixedly installed with a bottom bracket and a fixed gasket. A same rotary toothed piece is movably installed on a side of the bottom bracket and the fixed gasket close to each other. An inner wall of the toothed piece is movably installed with a limiting wood shaft. A threaded rod is movably installed on the limiting wood shaft, and is movably sheathed with a gasket located on a top side of the toothed piece. The threaded rod is sheathed with a nut, a piston piece is fixedly installed on a top side of the nut, and the piston piece contacts an inner wall of the inner tube.
