Title: Tamper-evident closure having improved drainage

Abstract: A closure having a tamper-evident band secured to a container neck by a retaining band. The tamper-evident band is attached to the retaining band by a hinge so that the retaining band rotates upward about the hinge when the closure is applied to the neck of a container, causing the inner wall of the retaining band and the inner wall of the tamper-evident band to form a cavity therebetween. A number of rectangular openings are spaced around the circumference of the retaining band. The upper edge of each opening extends beyond the hinge and into the tamper-evident band. A recess in the inner wall of the tamper-evident band is located above each opening so that the lower edge of the recess intersects with the rear wall of the opening. The openings and recesses cooperate to ensure that any liquid that spills or splashes from the container neck into the cavity during capping will drain out.
