ABSTRACT:
A molded thermoplastic closure having a heat shrinkable tamperproof band integrally attached to the lower outside circular edge of the closure skirt by means of circumferentially spaced bridge members. The outside diameter of the tamperproof band is greater than the outside diameter of the skirt, so that the tamperproof band extends at least partially beyond the circular lower skirt edge. The upper edge of the band can be located outside the skirt edge and be connected thereto only by the bridge members, or it can be located partially beneath the skirt and be directly integrally connected thereto through an annular region.
