Abstract
A threaded thermoplastic closure suitable for fitment to a threaded container neck is disclosed. The closure is provided with one or more vent grooves cut through the primary threads in the inner wall of the closure skirt. The ends of each thread segment are rounded and a smaller reinforcing secondary thread within the groove extends across the groove connecting the thread segments. The lower edge portion of the secondary thread is aligned with the lower edge portion of the adjacent segments of the primary thread to maximize the venting space over the secondary thread.
