Abstract: The following summary concerns the development of a folded leak-proof container (46) that consists of one piece of fiberboard or cardboard (1) containing slits and folds that produce the center panel (3), the top panel (4), the bottom panel (5), the side panels (6 and 7), and the end panels (8-15), the latter of which contain lengthwise slits (18-25) to be folded in order to form the side handles of the container (46); the container may also include a top handle (2). The main function of the container (46) is to keep cool, transport, and cool items that must be refrigerated; it can do so through the addition of ice or any coolant compatible with the material used to manufacture the container.
