Tray For The Transportation Of Products

Abstract

The tray comprises a bottom ( 1 ), a pair of sides ( 2 ) and a pair of headers ( 3 ), the sides ( 2 ) and the headers ( 3 ) comprising upper flaps ( 4, 5 ) engageable to each other, and it is characterized in that the flaps ( 5 ) of the headers comprise a pair of protrusions ( 6 ) which are inserted in complementary grooves ( 7 ) provided at the flaps ( 4 ) of the sides. The flaps ( 5 ) of the headers comprise a longitudinal folding line ( 9 ) and the flaps ( 5 ) of the headers also comprise a transversal folding line ( 15 ). It is obtained a tray provided with a lid, which is formed by said upper flaps of the headers and the sides, presenting a great stiffness, in the engagement between the flaps forming the lid and also in its resistance to compression when some trays are placed stacked.
