ABSTRACT:
At the top of a bottle the circumferential bead lying between the cap fastening means and the neck is enlarged in diameter to better meet the enlarged diameter of an oversize cap such as a two piece "child-resistant" cap. The undercut below the bead forming the neck is greatly exaggerated. The circumferential bead is located lower on the top to better fit the extended skirt length of the outer cap of the two piece "child-resistant" cap. A circumferential shoulder is added above the bead to substantially match the skirt length and diameter of a standard cap. Regardless of whether a "child-resistant" cap or a standard cap is used, the plastic shrink-fit band tightly fits about the cap and over and underneath the circumferential bead. The loosening of either "child resistant" or standard cap will force the splitting of the band because the shrinkage of the band below the circumferential bead is considerably greater than the innate circumferential elongation of the shrunk plastic band material.
