Cooling bag for large fish

Abstract

This is a large-fish insulated bag for transporting and storing large fish, such as tuna, while keeping them cool. It measures 2550 mm wide and 1550 mm long in the front view. As shown in the reference oblique view, this bag is formed as a single sheet and is used by folding it in half along the fold line indicated by the dashed line in the figure. This bag is made of two overlapping, flexible, and waterproof layers of fabric, sandwiched between them and a highly insulating material such as urethane. When in use, the left, right, and top edges are sealed with a series of waterproof zippers, preventing water leakage from the interior. Four water taps are provided on the front for releasing water from the interior. As shown in the reference oblique view, the unfolded bag can be placed halfway (upper right or lower left of the fold line) and folded back as described above. The bag can then be placed inside the bag by closing the waterproof zipper.
