Flasks

— it is customary to refer to flasks as tourist and sports drinking containers made of rigid materials and not having a thematic specialization (bicycle flask, classic flask, etc. — see the relevant paragraphs). Another characteristic feature of the flasks are screw caps (see "Functions/Features") — these corks are the main difference from bottles, while the shape of the flask can be almost identical to the bottles. However, such containers are available in a wide variety of shapes, volumes and designs; we only note that they rarely contain less than 500 mL — a small volume in this case is not justified.
