Patent abstract

Tamper-evident plastic container comprises a base portion having a base flange and a lid portion having a lid tab joined to the base flange by a hinge, wherein the lid portion has at least one grip tab extending outwardly beyond the base flange. The lid portion is configured to lockingly engage the base portion in a closed position. One of the base flange or the lid tab has a path of weakness formed therein to define a frangible connection, wherein the frangible connection is configured to be ruptured to initially open the lid portion from the closed position. The path of weakness is spaced from the hinge to define a tamper indicator region between the path of weakness and the hinge, wherein the tamper indicator region remains joined to the hinge after the frangible connection is ruptured. Methods of containing a product in a tamper-evident container are also disclosed.
