ABSTRACT:
A lid and cup assembly for storing and dispensing comestibles is disclosed which provides a tamper-evident package to indicate unauthorized tampering. The tamper-evident package for storing and dispensing comestibles and the like, includes a cup formed of a sidewall member having at its open end a rim with an unrolled peripheral edge. The package also includes a lid configured and dimensioned for engagement with the cup at its open end. The lid includes a panel member having along its periphery an annular rib configured and dimensioned so as to snap-fittingly and sealingly engage the cup. The annular rib is formed of an inner wall an outer wall and a transverse top wall. The outer wall has three spaced apart detent ribs of predetermined length for securing engagement with the cup peripheral edge at least when the lid is pried off. The outer wall also has adjacent at least one of the detent ribs a pair of tear lines on each side of the respective detent rib. The top wall has a hinge groove therealong engaging the rim of the cup so as to provide a pressure and a vacuum seal and so that when the outer wall member is pulled outwardly away from engagement with the cup peripheral edge, at least a portion of the outer wall breaks from the remaining portion at least at the tear lines and hinges about the groove while the pressure and said vacuum seal engagement remains intact to provide evidence of unauthorized tampering.
A method for forming the tamper-evident package is also disclosed.
