Upper cover consists of integral wings of side and end face walls which are bent relative to each other and relative to walls. End face walls are preliminarily bent inwards to required shape so that when wings of side walls are bent off to overlap each other to form upper cover, wings of end face walls form projecting triangular flaps which are bent downwards overcoming increasing resistance until they are set at definite angle of deflection downwards below horizontal line. Then end face walls are bent inwards to let side walls meet each other to reduce resistance and provide effort tending to tilt flaps downwards for bringing them into engagement with side walls to hold flaps on end face walls and hold wings of side walls of upper cover closed. EFFECT: enlarged operating capabilities.
