ABSTRACT:
The invention relates to a carton tray with a separate carton cover, the side walls of which form a continuous frame around the edges of the cover base and fit the upper end of the tray which is provided with downwardly foldable edge flaps intended to engage with the inside of the frame formed by the side walls of the cover when placed on the tray. The side walls of the cover are extended at their ends with end flaps lying along the inside of the frame formed by the side walls. At least some of the end flaps have a locking edge turned upwardly towards the base of the cover, said edges being substantially parallel to the cover base and at a predetermined distance below it. At least some of the edge flaps of the tray have in their outwardly and downwardly folded position a downwardly turned locking edge for cooperation with a corresponding locking edge of the respective end flap so that, when the cover is pressed down onto the tray, the respective locking edge of the cover in the region of the completely pressed-down position of the cover will pass over the locking edge of the adjacent edge flap so that the edge flap snaps into position and both locking edges come into locking abutment with each other.
