Abstract
A container lid having a removable portion which can be torn off by a tear tab. It has an upwardly projecting wall defining the periphery of the removable portion and formed by bending the plate from which the lid is formed. The wall protects a person opening the container against any injury by the torn edge of the removable portion. The wall also contributes to reducing the force which is required for tearing off the removable portion.
