One of the more popular styles of closures for the Mason jar was the wire bail.
The closure consists of a metal wire arrangement with a lever that applies leverage to a glass lid when pivoted downward against the side of the jar, clamping it down over a separate rubber O ring.
The court ruled that Mason's delay in protecting his patent indicated he had abandoned his invention in the intervening years between 18 and had forfeited his patent.
The court's decision allowed other manufacturers to patent, produce, and sell glass jars for canning.
On January 5, 1875, Charles de Quillfeldt of New York City invented a wire-bail closure known as the Lightning closure.
While the bands are reusable, the lids are intended for single use when canning.
The band, when screwed down, presses a separate stamped tin-plated steel disc-shaped lid against the jar's rim.
An integral rubber ring on the underside of the lid creates a hermetic seal.
A Mason jar, named after John Landis Mason who first invented and patented it in 1858, is a molded glass jar used in home canning to preserve food.
The jar's mouth has a screw thread on its outer perimeter to accept a metal ring (or "band").
