ABSTRACT:
A tamper evident container assembly includes a container body having a bottom wall and peripheral side wall, the side wall terminating in an outwardly curled rim. A reusable lid includes a top wall portion and a depending skirt portion, the depending skirt portion constructed of spiral wound stock and having a free end, a major peripheral portion of the free end tucked under the upper rim and upwardly into engagement with the side wall, with a minor peripheral portion of the free end left untucked to thereby provide a gripping area to facilitate tearing and removal of the tear strip. The depending skirt portion is further provided in a lower portion thereof with a line of weakening extending annularly about the skirt portion to thereby define an annular removable tear strip inclusive of the free end, with the line of weakening lying on the rim, between upper and lower edges of the rim. Apparatus for forming the assembly includes a device for pressing a lower portion of the depending skirt portion of the lid under and into engagement with the rim of the container to form a curl about a major peripheral portion of the lid while leaving a minor peripheral portion uncurled while simultaneously forming a vertical slit in the lower portion of the depending skirt portion at an interface between the curled and uncurled portions to thereby simultaneously form a grip tab. Another device is provided for orienting the container to a predetermined rotational position prior to securing the lid. A related method of securing the lid to the container is also disclosed.
