Abstract: The invention concerns a tray blank, especially for eggs, having one or more upwardly extending projections, the diameter of each of said projections decreases in the upward direction, the lateral wall of each projection together with other wall sections adjacent to the projection comprising walls defining cell-shaped, upwardly open compartments adjoining the projection and intended to receive eggs. The projection is formed with an open projection which is slit downwardly from the top, starting from the upper, free edge of the wall of the projection, the wall sections defined by the slits continuing downwardly into the cell-shaped compartments and are formed as resilient surfaces supporting the eggs.
