1. A stackable tray obtained by vacuum molding of a sheet of plastic material, said tray comprising, in open position: a) a top and a bottom; b) a plurality of receiving cavities opened upwardly; c) a hinge portion dividing said tray into a cover portion and a base portion; said receiving cavities being provided in said base portion, and said cover portion defining a substantially flat surface above the receiving cavities when the cover portion is folded over the base portion to close the tray in a closed position to define a box, the substantially flat portion spanning at least partially above all rows of the receiving cavities; d) spacing means to keep, in a stack of trays, the top portion and the bottom portion of neighboring trays at distance from each other to thereby prevent interlocking therebetween when the trays are in an opened position; and e) at least one two-part locking means, each part being provided in the top of the sheet and positioned to engage one part into the other part when the cover portion is folded over the base portion along the hinge portion to bring the tray into the closed position, the part in the cover portion forming a concavity in the substantially flat surface by projecting from the substantially flat surface toward the base portion when the tray is in the closed position and transversely oriented with respect to the hinge portion to sit on at least two other parts in the base portion such that the part in the cover portion spans over the at least two other parts in the base portion, the parts in the base portion each being positioned between some of the receiving cavities and being separated from one another by row of the receiving cavities.
