  • Sloped bottom tank
    Patent number: 5878902
    Abstract: An improved tank configuration includes a die employed to stamp a formed member. The formed member may be used as the bottom head for a portable liquid container, and is constructed so that all welding is eliminated in the corner portions of the container. A trim machine is employed to remove uneven edges from the formed part. The invention is particularly useful in constructing sloped bottom tanks of increased depth. 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 bottom head is finish trimmed to exact dimensions so as to facilitate assembly to the shell of the tank.
