Abstract
A dual wall storage container assembly is provided for storing liquids. The container includes a one-piece, molded inner tank which can be installed and removed from a molded outer tank. Notches are provided adjacent the bottom of the outer tank to align the inner tank within the outer tank. A horizontal shelf surrounds the mouth of the outer tank, with a horizontal shoulder on the top of the inner tank overlying the shelf. A seal is provided between the shelf and the shoulder to inhibit moisture migration. A drip edge is provided on the top outer perimeter of the inner tank to further inhibit moisture migration between the shelf and the shoulder. A tab on the shoulder is received in a notch in the shelf to preclude rotation between the nested tanks. Lifting flanges on the outer tank allow both tanks to be lifted simultaneously while nested together.
