Abstract
The present invention relates to a method and apparatus for molding a tamper-evident closure with tabs that extend radially inward and upward. In order to produce tabs with such a configuration, the present invention employs a tab forming element having a mold surface with an inclination corresponding to the degree to which the tabs are desired to extend radially inward and upward. After the tabs have been molded in their inclined position, they are withdrawn from the mold, temporarily altering their angle of inclination. After removal of the closure from the a first portion of the mold, the tabs are returned to the original angle of inclination through contact with a second portion of the mold.
