ABSTRACT:
A single and unitary, generally rectangular blank is preferably made of corrugated cardboard, with a waterproof surface. On the corners of the blank, a pair of triangular panels are brought together, in a V-fold, and into a face-to-face contact. Then, the corner panels are folded over the ends of a box as the four sides of the rectangular blank are raised to form the side and end panels of a five-sided box. A cover panel is integrally joined to one edge of a side panel, to swing down and close the box. While the leakproof box has many uses, it is presently thought that it will primarily be used to ship frozen poultry.
