The stopper or lid was typically made from metal, porcelain, or ceramic, while a rubber gasket was used to seal the container. The sealing surface on the jar was a "shelf" that supported the lower edge of the lid.Putnam modified de Quillfeldt's design so that the lid was secured by centering the wire bail between two raised dots or in a groove along the lid's center. A rubber gasket between the shelf and the bottom surface of the lid formed a secure seal when the wire closure was tightened.Between 18, many other patents were issued for Mason jar improvements and closures.

French chef Nicolas Appert invented the method of preserving food by enclosing it in sealed containers.The bands and lids usually come with new jars, but they are also sold separately.While the bands are reusable, the lids are intended for single use when canning.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."Patent Nov 30th 1858," signifying the date of Mason's patent, was embossed on thousands of jars, which were made in many shapes, sizes, and colors well into the 1900s.Since they were made in such quantity and used for such long periods, many of them have survived to the present day.A band is screwed loosely over the lid, allowing air and steam to escape.The jar is heat sterilized in boiling water or steam and the lid is secured.
