Abstract
An easily-opened container includes a container body with an opening portion and a lid cooperating with the opening portion. The lid has a central lid portion and a peripheral portion located outside this lid portion and sealingly and permanently fixed to the opening portion for closing the container. The central lid portion and the peripheral portion are separated from one another by a weakened portion which extends in the circumferential direction of the opening portion and at least partially around the opening portion. In a restricted region, the opening portion is provided with a recess located beneath the weakened portion. A stripping unit with fulcrum-effect is pivotally supported in a support region. The stripping device has a pull member and a pressure member, the latter abutting against the outer surface of the lid inside the weakened portion and above the recess in order, on lifting the pull member, to realize, by pressure against the above-mentioned region, material rupture in the weakened portion and thereby initiate opening of the container.
