ABSTRACT:
A foldable water tank includes a foldable receptacle having a bottom wall and vertical sidewalls; and a folding frame to support the sidewalls in an upright position. The frame has first, second, third and fourth upper rails joined end-to-end. The frame has a folded position wherein the upper rails are adjacent to each other. First hinges disposed at end portions of said upper rails pivotably connect the upper rails. The second and fourth rails each includes first and second sections having adjacent end portions. Second hinges connect the adjacent end portions to allow the second and fourth rails to fold inwardly to be disposed between the first and third rails in the folded position. The second hinges each includes a shield to cover the adjacent end portions thereby to protect a user's hand from being pinched by the adjacent end portions during unfolding or folding of the frame.
