Abstract
Abstract A cold temperature chilling storage and transportation container specifically is used for fish. The space between double walls of regular or crosslinked polyethylene is filled with polyurethane foam. The outer bottom wall has nine legs formed integrally therewith. The inner bottom wall slopes to a recessed one inch opening in which a plug may be inserted. The upper half of the sidewalls extends outward about an inch and a half on each side so that empty containers may be telescoped. A cover overhangs the outer wall and has lower recesses to receive the sidewall. Nine upper recesses in the cover receive legs of the bottom wall for stacking the containers. The legs enable a forklift to be inserted from either side. A hollow double walled air manifold fits within the bottom and has a nipple to which an air hose may be connected. In use, ice is placed in the container, later, salt water and fish are added. Air under one hundred pounds a square inch is released through the manifold bubbling through the saline ice mixture and quickly chilling the fish. The air hose is left attached or may be quickly disconnected from the manifold, and the cover is placed on the box, maintaining the fish in chilled condition over an extended period of time.
