Abstract
Abstract The invention concerns a double wall container for shipping perishable goods, such as fish which must be kept cold. The container has a foamed plastic inner boxlike part open at the top and having a lid. The container also has an unfoamed plastic outer part which embraces the inner part at the top top thereof but is spaced from the inner part at the sides, ends, and bottom of the inner part, a drain opening in the bottom wall of the inner part drains fluids, as from melted ice, into the space between the parts and the outer part has a drain port which can be opened when desired. The container is arranged for being stacked in interlocking relation with other like containers and can be provided with banding straps to lock the lid in place or to hold stacked containers together.
