ABSTRACT:
A tamper evident container in which the container bottom has an outwardly extending lip at the top and the lid has a downwardly extending shirt which includes a tear-strip. The tear-strip has a locking ring which is hinged to the tear-strip so that it may stably occupy either of two positions. The first position being downward and the second position being upward to engage the lip when the lid is first used. The pushing of the lid downwardly moves the ring from the first to the second position to prevent removal of the lid without use of the tear-strip.
