It works by preventing heat leaving - or entering - the flask in three ways. Firstly, the inside is coated with a silver finish that prevents heat radiating out, or, in the case of chilled drinks, radiating in. Next, the double wall design creates a pocket of air between the inner surface and the outer one. This prevents heat loss - or gain -  via conduction, which happens when two surfaces touch. Think burning your hand when touching a hot surface. That's conduction! The last way vacuum flasks retain heat is by stopping convection - or the movement of heat through gas or liquid. The airtight lid of a vacuum flask prevents this happening by stopping air entering or leaving the vessel.","brand":"Uropa","offers":[{"title":"Default Title","offer_id":49196384289087,"sku":"CN696","price":9.29,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0738\/3865\/7855\/files\/cn696_vacuumflask1.jpg?v=1718455010","url":"https:\/\/cateringprojectsshop.com\/products\/olympia-vacuum-flask-stainless-steel-1ltr","provider":"Catering Projects Shop","version":"1.0","type":"link"}
