The term "screw top" refers to the method of bottle closure used for certain types of containers, particularly for liquids. In the late 19th century, glass bottles with cork stoppers were commonly used for various products such as medicines, perfumes, and spirits. However, this method of closure had several drawbacks, including the high cost of cork stoppers and the potential for taint or deterioration due to exposure to air and light. In the early 1890s, the French chemist E. J. Gay Lussac Jr. Invented a new method of bottle closure using a threaded neck and a fluted, threaded closure, which he called the "GREENHART," after his family name. The closure consisted of a cup or flange underneath the bottle, which was then secured with a threaded metal cap fastened by a screw. The concept of the screw top became more popular in the late 1800s, and by the end of the century, companies such as Canadian Cork Limited and Brown, Shipley & Co. Had begun marketing their screw top products. In the 20th century, the development of new materials and processes further improved the efficiency and affordability of screw caps, making them a popular and practical choice for various applications. Today, screw tops are commonly used for several products, including cosmetics, pharmaceuticals, household cleaners, and foods such as pickles, jams, and mayonnaise. They offer several benefits such as improved convenience, sanitation, and stability of product contents, as well as reduced waste compared to traditional stoppers or caps. In conclusion, the term "screw top" refers to a type of bottle closure that became popular in the late 1800s due to its practicality, efficiency, and affordability compared to traditional cork stoppers. The method involves a threaded neck and a fluted, threaded closure, also known as a cap, which is fastened by a screw. The concept gained wide acceptance by the turn of the century, and it remains a popular choice for various products today due to its numerous benefits.
