Abstract
The neck of a plastic container of the type originally intended for use with a foil type closure is formed with a top bead, a first reduced-diameter step and a second reduced-diameter portion and then a downward-outward widening breast. The cap has a top disk which seats on the neck and has an outer skirt having an internal upper bead engaging under the top bead and a second internal bead fitting deeply into the second reduced-diameter portion. An inner skirt depends from the disk and fits inside the neck. Thus the cap seats tightly on the container neck. To remove the cap, a circumferential internal weakened portion is formed in the outer skirt. A curved weakened portion extends up from the bottom edge of the outer skirt and merges with the circumferential weakened portion. A pull tab depends from the bottom edge of the skirt. By pulling upward on the tab, the portion of the outer skirt below the first reduced-diameter portion of the neck is torn away. The remainder of the cap may be snapped off and later replaced for reclosure.
