The side wall segments each include a tab element that is foldably attached to a lateral edge thereof and which is secured to the outer surface of the next adjacent side wall when the receptacle is formed. Meanwhile, the peripheral flange segments each include extensions at the ends thereof which become interlocked when the receptacle is being formed, and that are secured alternately to the outer and inner surfaces of the adjacent flange panels.
