Invention herewith described refers to the box in the shape of a shallow vessel for packing and transportation of fruits and vegetables made of the corrugated cardboard panels, the cardboard or the synthetic materials. By punching the panel of the above mentioned materials there is obtained the developed form of box construction that allows the box to be easily, quickly and simply hand shaped by bending the sides (2) and the side flaps (4) first and then successively: side faces (3), side face flaps (5 ) and the wing extensions (6).The final assembling and the stiffening of the box (P) are performed with a split connection by inserting the tacks (F) through the circular openings (8) made in the mutually resting sides (2) and the wing extensions (6).The tack (F) consists of two elements joined by penetration of one element into another elements hole, whereat the penetration, joining and separation of these elements is provided by their design and elasticity.
