Tips
- Thermos flasks come in a wide range of sizes, so it’s good to work out what you really need. If it’s too big, you risk wastage. If it’s too small, it might leave you short.
- Similarly, think about how long you need to keep things warm. Beverage bottles with greater heat retention properties are often the more expensive ones on the market.
- Choose a thermos flask with a lid that can double as a travel mug if you’re going to be outdoors and don’t want to carry unnecessary extras.
FAQs
Q: How does a vacuum flask work?
A: A vacuum flask is constructed with an internal double wall of stainless steel or glass to prevent heat transfer. Because heat can’t get in or out past these layers, the temperature inside doesn’t change, and the liquid stays either piping hot or ice cold.
Q: Can I put my thermos flask in the dishwasher?
A: Most thermos flasks are dishwasher-safe on the top rack, but manufacturers often recommend hand-cleaning to protect the exterior finish. Never use bleach to clean a flask.
Q: Can I use my vacuum flask to keep food warm?
A: There’s no reason why you can’t use your thermos as a food flask as long as the lid is wide enough to accommodate whatever you’re having for lunch. You can also buy vacuum insulated food jars specifically designed for this purpose.
