Vintage King Seeley Thermos

Vintage King Seeley Thermos, likely from the 1960s or 1970s. Insulation: King Seeley Thermoses use a vacuum between two layers of glass or metal to keep contents hot or cold for extended periods. Construction: They are typically made with a metal or plastic outer casing, a glass or stainless steel inner liner, and a stopper to seal the contents. Design: Often feature a brown or tan color with stripes or other decorative elements. Brand: King Seeley Thermos Co. was a popular brand of vacuum-insulated bottles and lunchboxes. History: The vacuum flask was invented by Sir James Dewar in 1892. Reinhold Burger and Albert Aschenbrenner created a domestic version of the vacuum flask and secured a patent in 1904. The name "Thermos" was derived from the Greek word "thérmē," meaning heat. King-Seeley Thermos Co. was a prominent manufacturer of these thermoses in the mid-20th century. The term "thermos" became so widely used that it became a generic term for vacuum-insulated bottles. Uses: King Seeley Thermoses were commonly used to keep beverages like coffee, tea, and soup hot or cold. They were also used to store food items and were popular for lunchboxes and picnics. Care and Maintenance: It's important to handle glass-lined thermoses carefully to avoid breakage. Do not overfill the thermos, and avoid using abrasive cleaners. Check for any damage or cracks before use. Modern Thermoses: Today, many brands offer high-quality thermoses with improved insulation and features. Some popular brands include Zojirushi, Stanley, and Hydro Flask.
