Morphology

thermos + bottle

The meaning is directly compositional: 'thermos' already denotes a vacuum-sealed container and 'bottle' specifies its form, so a B1 learner who knows both words can readily infer a bottle designed to keep liquids hot or cold. The structure and concept are cross-linguistically common (e.g. termo/thermos in many languages), making the expression immediately comprehensible.

Etymology

Thermos bottle gets its name from the Greek word thermos meaning 'hot' and from the simple image of a bottle inside another bottle with empty space between them. That empty space stops heat from leaving, so a thermos bottle keeps drinks hot or cold for a long time.
