A Thermos is a type of insulated container that is designed to keep liquids or food hot or cold for an extended period of time. The container is typically made of stainless steel, plastic, or glass and is insulated with a vacuum between the two walls. This vacuum insulation keeps the temperature of the liquid or food inside the container constant, regardless of the temperature of the environment. The insulation also prevents heat transfer from the inside to the outside, making it ideal for keeping food or drink hot or cold for hours. One interesting aspect of Thermos is its history. The first vacuum flask was invented by Sir James Dewar in 1892. He was attempting to create a container that could store liquid gases at low temperatures, and found that a double-walled container with a vacuum in between was the most effective design. The Thermos company was founded in 1904 and began producing vacuum flasks for commercial use. Since then, Thermos has become a household name and a popular item for outdoor enthusiasts, commuters, and anyone who wants to keep their drinks hot or cold for long periods of time. Another important aspect of Thermos is its environmental impact. While vacuum flasks are a great way to reduce waste by avoiding disposable cups and bottles, the production of Thermos containers still has an impact on the environment. Some companies are now producing eco-friendly Thermos containers made from sustainable materials like bamboo or recycled plastic. Additionally, some Thermos containers are designed to be easily disassembled for recycling at the end of their life. Overall, Thermos is a versatile and useful invention that has become a staple in many households and workplaces. Its ability to keep drinks and food at a consistent temperature for hours makes it a valuable tool for anyone who wants to enjoy a hot or cold beverage or meal on the go.

Thermos is a brand of vacuum flask designed to keep beverages hot or cold for extended periods of time. It is constructed with two glass layers enclosing an inner vacuum layer, which is a hermetically sealed metallic vessel, and is kept in place with stoppers or clips. It is a unique and highly effective vessel for preserving the temperature of the liquid contents inside. As such, it has become incredibly popular around the world for its ability to keep beverages like coffee and tea hot for extended periods of time. In other languages, thermos is often referred to as a thermosflasche (German), termoska (Polish), termos (Danish), termosfles (Dutch), termosai (Lithuanian), termoss (Finnish), θερμός (Greek), termospullo (Finnish), termosica (Croatian), termosas (Latvian), termos (Swedish), termoska (Czech), termos (Norwegian), térmica (Portuguese), termos (Hungarian) and termosu (Estonian).

Language evolution, evolution of terms, Greek origin, Semantics, Morphology.
The word 'Thermos' is an interesting example of an etymological, linguistic and morphological evolution. It has its origins in the Greek language, deriving from the word therme which means 'hot' or 'warm'. This term was then adopted into the English language but with a slightly different spelling, 'Thermos', presumably to differentiate the word from other related words such as thermometer or thermodynamics. Through years of usage, the term has taken on a specialised meaning, referring to a specific type of container that is able to maintain the temperature of its contents. This is a product of morphological change, as the morphological structure of the word reflects the specific use of the term. Moreover, the term 'Thermos' has become popularly used as a generic term that is employed to refer to a wide variety of containers which are designed to keep their contents at a fixed temperature. Pragmatically speaking, the term has become a tool for certain kinds of communication, allowing speakers to precisely and efficiently convey a specific meaning.
