Abstract

An easy-open package has a vessel having an annular peripheral rim and at least one crosswise rib forming with the rim a plurality of upwardly open compartments, a foil engaging the generally coplanar upper edges of the rim and rib of the vessel, formed with a tear line extending around the rim, and provided with an open tab attached to the foil within the tear line, and repsective rim and rib hermetic bonds securing the upper edges of the rim and rib to the foil. When the individual compartments are to be kept separate, the foil is formed with an annular tear line around each such compartment and is provided within each tear line with a respective such open tab.
