Abstract
An easy-open package comprises a vessel part forming an upwardly open compartment and having an annular rim surrounding the compartment and a foil part adhered to the rim of the vessel part all around the compartment, unitarily formed with 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 to an outer periphery of the foil part to each side of the tab. One of the parts is formed as a laminate including a metal layer, a synthetic-resin layer, and a relatively weak bond securing the synthetic-resin layer to the metal layer. The synthetic-resin layer of the one part is bonded to the other part along an annular strip running around the rim with a relatively strong bond and the one part is formed in the synthetic-resin layer with at least one secondary tear line at the tab.
