    Abstract: Thermoplastic containers having a single open end of improved vertical strength properties are secured by employing a series of interconnected, vertically disposed supporting columns as part of the wall of the container. Preferably, the supporting columns extend laterally, outwardly from the noncolumn containing surface of the container sidewall. Each of the columns comprises two substantially identical isosceles trapezoids, each having a base and a side opposite therefrom of from 25 to 75 percent of the length of the base, and an elongated rectangular member of a length substantially equal to the length of the base of the trapezoids. The rectangular member is positioned between and connected to the bases of the trapezoids. Successive columns are interconnected along the side opposite the base of the trapezoids.
