A precursor to the flip-top, the "bail" or "Kilner" closure was invented in 1859, where a lid with gasket was held by a wire harness and sealed by a separate set of wires. Examples of flip-top bottles. The first flip-top closure was created by Charles de Quillfeldt in the United States, who filed for a patent on 30 November 1874.
The Fowler's Vacola system uses glass jars, single use rubber ring seals and pressed metal lids, much like American Mason jars first patented in 1858, except that the jars and lids are not threaded. During the canning process, while still hot (and presumably sterile ), the lids are secured by metal tension clips which are removed once cooled ...
A jar's age and rarity can be determined by the color, shape, mold and production marks of the glass, and the jar's closure. Mason jars usually have a proprietary brand embossed on the jar.

It is designed to grip a bare wire ...
A crocodile clip or alligator clip [1] is a plier-like spring-tensioned metal clip with elongated, serrated jaws that is used for creating a temporary electrical connection. This simple mechanical device gets its name from the resemblance of its serrated jaws to the toothed jaws of a crocodile or alligator .
