Abstract
An easy-open package has a vessel forming an upwardly open compartment and having an annular rim surrounding the compartment and a foil engaging the rim of the vessel part all around the compartment, having an open tab which projects laterally past the rim, and formed with a tear line extending around the compartment except at the tab and extending around and delimiting of the tab. The tab is unitarily formed with the foil and is connected to the foil by an integral web that overlies and is bonded to the rim. The bond between the foil and the vessel is substantially weaker at the web than elsewhere.
