The invention refers to a locking means for fixing a lid to a tray, said locking means is located on at least one of the side walls (B, C) of the lid (O) and the tray (P) respectively, which during the fixing of the lid (O) over the tray (P) are meeting each other wrap-over, when that side wall (B) of the lid (O), which is provided with the locking means (F) extends mainly downwards to the bottom (D) of the tray (P) at the same time as the side wall (B) of the lid (O) is situated within the side wall (C) of the tray (P). The locking means (F) comprises a recess (M) extending along the bottom (D) of the tray (P) and at its side wall (C), said recess having an upper edge portion (S), which when the lid (O) is fixed to the tray (P) mainly coincides with a slot (T) extending in the side wall (B) adjacent said lid (O) in creating a locking flap (H) in said side wall (B) and that an automatic locking of said lid (O) to the tray (P) occurs by that the lower side wall portion of the Hd (O) below the slot or the locking flap (H), is, by aid of its upper edge (I) formed in said slot (T), fixable into position against the upper edge portion (S) of the recess (M) at the same time as the locking flap (H) is extensible or can be pressed out in a direction outwards in said recess (M). |
