ABSTRACT:
An improved bottle cap particularly useful for returnable containers is disclosed. The cap is composed of a top disk, a thin-walled cylindrical outer skirt and a coaxial inner skirt. The outer skirt is weakened along two circumferential score lines which traverse the skirt in an arc of about 250.degree. to 358.degree. forming a weakened cylindrical band around most of the outer skirt. A narrow strip connecting the upper portion of the skirt to the lower portion is left between the incompleted arc. At least one vertical score line extends downwardly from the lower circumferential score line to the bottom edge of the outer skirt. A tab is attached to the cylindrical band to provide a means whereby a person may grasp the tab between the fingers and tear the band from the cap. Two circumferential beads traverse the inside of the outer skirt with one bead being disposed above the upper score line and one bead below it. When the band is removed, the upper portion of the cap may be removed and used as a reclosure cover. The lower portion is torn from the container by the connecting narrow strip thereby allowing the container to be recycled.
