FOAMED CONTAINER

PROBLEM TO BE SOLVED: To suppress the invasion of air from the outside during transporting fish while improving discharge efficiency of seawater in a foam container capable of generating platelike ice gorge by discharging only seawater from slurry ice. SOLUTION: A plurality of water drop holes 6 communicating to a fish body storage part 4 and a flat tunnel part 7 communicating to the water drop holes 6 and the outside of the container are provided on the bottom surface 2 of the foam container 1. When the slurry ice composed of small pieces of ice and the seawater is charged, the seawater is separated from the small pieces of ice before the temperature of the seawater lowers near the freezing point since the only seawater is rapidly dropped into the water drop holes 6. Closure of the water drop hole 6 and the tunnel part 7 due to the freeze is delayed to allow a much larger quantity of seawater to discharge, the slurry ice remaining in the fish body storage part 4 becomes more rigid, and the platelike ice gorge having high cold-insulating property can be obtained. Moreover, ice melt water during transporting of the fish body becomes water droplet 8 to retain in the tunnel part 7 through the flat tunnel part 7 to block the tunnel part 7.
