Abstract: The invention resides in a lid for containers of the type having a pull tab attached to a separable panel on the lid. The lid is weakened along a line to define the panel which can be removed or bent to give access to the contents of the container. The panel has a well over which the pull tab extends to enable the tab to be lifted by a finger inserted in the well. The panel has a raised horseshoe shaped portion near the line of weakening. The bight of the horseshoe forms part of the well's perimeter and the end of the tab to be lifted is disposed between the legs of the horseshoe. Upon lifting of the tab end, the opposite end of the tab initiates fracture of the panel along the weakened line.
