Such a bottle conventionally has an external bead a short distance below the top of the neck. The cover has a skirt formed with a complementary bead which fits tightly over such bead, the plastic material stretching sufficiently for the cover to lock into place so that it cannot be removed with the skirt intact. A tear strip is formed substantially circumferentially around the cap bead by a pair of vertically spaced score-lines. The skirt is grooved to form a tear tab which extends circumferentially along a portion of the bottle bead. By tearing off the tear strip the portion of the cap thereabove can be removed. As a supplemental means of access for removal of the cork, the top disc of the cap may be formed with a circular score-line. | |
