2 circumference the distance between the slits 10 at the beginning of each slit along the upper edge of the bracket plate 4 is therefore slightly narrower than the outer diameter of the projection 2 and the circular undercut 18 on the bottom of the bracket plate 4 beneath the ends of the slits the bracket plate 4 merges at a hinge like transition 13 with a carrying handle 12 whose upward movement is limited by an abutment 14 on the handle engaging the upper side of the flap which acts as an opposing abutment to attach the handle to the container the bracket plate 4 is placed against the bottom of the projection 2 of the container and pushed upward the flap 16 bends easily back and does not mate fully with the projection 2 until the plate has been pushed all the way up and the flap snapped down over the projection 2 the undercut 18 engages the outer edge of the projection 2 with a slight bias in addition to the saving of time in this embodiment a saving of weight and material is also obtained in the example shown in fig5 a specially designed upper abutment is provided on the outer surface of the flap 16 of the.
