A reclosable container assembly (10) includes a container (12) having a locking ledge (18) thereon and a closure member (14) having a locking skirt (34) thereon. A tamper indicator and tear-off strip (44) which has a plurality of spaced apart grooves (60) defined in the inner surface (54) thereof is attached to the closure member skirt by a hinge 50. A web (62) covers each groove so that the tear-off strip outer member appears smooth. The web over each groove is adapted to break when a relatively small force is applied at any location along the tear-off strip between the grooves to indicate that the assembly has been tampered with.
