WATER CONTAINER HARDLY CAUSING LEAKAGE OF WATER AND USED FOR BREEDING OR TRANSPORTATION OF AQUATIC ORGANISM

PROBLEM TO BE SOLVED: To obtain a water container hardly causing leakage even if the placing posture is arbitrarily changed in 360 deg., capable of allowing oxygen, etc., required for the aquatic organism to be continuously supplied from the outside, and further allowing water to be transported without spilling while housing a live small fish or the like therein. SOLUTION: The outside of the water container is formed into a structure closed by a structural wall 1a' of a main body so that water may not leak. Because the supply of oxygen or the like cannot be carried out in a closed state, the water container having a channel 3a' from which air from the outside goes in and out is formed at the position estimated as the center of gravity when the hollow part of the water container is filled with water, etc., or the neighboring position thereof. A special-purpose hanging tool for hanging by hand, and a shouldering belt, etc., can be installed in the water container.
