ABSTRACT:
There is disclosed a cup-like container closure of resilient and flexible thermoplastic material having a removable tear strip defined by an annular groove on the inner surface of the closure skirt. The tear strip includes a gripping portion adjacent opposite ends of the strip which are separated by a narrow gap. The closure skirt is substantially cylindrical and free from outwardly depending portions. Contents of the container are effectively sealed therein by tight interengagement of cooperating surfaces of the container and the closure. The closure is re-usable for closing the container after removal of the tear strip.
