ABSTRACT:
A container having a base, a sidewall extending from the periphery of the base and defining an open top, and a closure sealing the open top, is provided with a secondary closure. The secondary closure comprises a band of heat-shrinkable thermoplastic adhesive tape extending around the periphery of the container at the level of a seam formed by the closure and the sidewall such that the adhesive side faces the container. The tape is heat-shrunk into compressive engagement with the container, and a portion of the tape is adhesively attached to the closure, with another portion of the tape being adhesively attached to the sidewall. One end of the tape overlaps an opposite end of the tape and is adhesively secured thereto. A gripping tab is formed of juxtaposed, folded, integral adhesively attached portions of the tape, and is positioned inwardly of the overlapping tape end which adhesively retains the gripping tab in place.
