ABSTRACT:
An improved tank configuration wherein a die is employed to stamp a formed member is disclosed. The formed member may be used as either the top or bottom head for a portable liquid container, and is constructed so that all welding is eliminated in the corner and outlet portions of the container. A trim machine is employed to remove uneven edges from the formed part. By the present invention, a stamped configuration is provided in which a draw formed tank bottom is formed so as to allow complete and full drainage of the tank bottom. The top and bottom heads are finish trimmed to exact dimensions so as to facilitate the assembly of these parts to the shell of the tank.
