noun
flask
FLASK/flæsk/
A small, narrow-necked container for holding liquids.
The small steel flask rests beside its removable screw cap.

Etymology
Latin flasco meant a bottle or container, so the modern portable liquid container preserves its basic function. The word's deeper origin is uncertain; a connection with plaited bottle coverings is only one theory.
In context
