Thermos Stainless King Matt Black Food Flask (470ml) – 9h Hot / 14h Cold
Product description
What it is and what it’s for
The Thermos Stainless King Matt Black Food Flask is a compact insulated jar designed to keep meals warm or cold on the move. It uses Thermos’ vacuum insulation to help maintain temperature across the day, with a 470ml capacity aimed at daily lunches, picnics, commutes or short trips. On the surface, it resembles a practical everyday container: sturdy stainless steel inside and out, a practical wide mouth for easy filling and cleaning, and a lid that doubles as a small bowl. On the page, this model is listed with hot retention and cold retention claims that vary by source, so it’s reasonable to view the product as aiming to keep hot foods warm for a long stretch and cold foods cool for a substantial period. If you prioritise a low-maintenance, all-in-one container for meals away from home, this model is worth a closer look.
How it performs in real life
In theory, the jar is designed to perform through a full day of meals. The steel construction is meant to be durable for daily use, resisting dents and wear that can come from stowage in bags or cupboards. The insulated lid is a small but helpful detail: it acts as a bowl, cutting down on extra washing up when you’re at work, on a hike, or heading to class. A wide-mouth opening should make filling and cleaning less fiddly, and the container is described as sweat-proof with cold contents, which helps keep hands dry and reduces surface condensation. In practice, whether you’re dealing with leftovers, a hot soup, or a chilled pasta dish, this design aims to keep serving temperatures reasonable while remaining approachable to use day after day.
What stands out, and where it might fall short
On the upside, the wide mouth, durable build, and multipurpose lid are straightforward advantages for practical daily use. If you value a single vessel that travels with you from kettle to canteen, the ability to avoid extra dishes is appealing. Still, there are a few caveats to bear in mind. The temperature figures listed across sources sometimes conflict (9h hot in the product name vs 14h hot/24h cold in the description), which means real-world results may vary with contents, initial temperatures, and external conditions. For someone seeking precise, lab-tested performance figures, such ambiguity could be a limit. The 470ml capacity is convenient for one meal, but if you regularly pack larger portions or multiple courses, you might reach the top edge of what this size comfortably holds.
Who it’s best for
This flask is a sensible pick if you want a robust, travel-friendly jar for day-to-day meals, especially when you’re out and about and want to carry everything in one container. It suits someone who values a safe, click-and-go solution with a lid that doubles as a bowl, and who isn’t chasing ultra-high-end temperature claims. It’s also suitable for those who prefer a single purchase with long-lasting insulation, given the stainless steel construction and practical design. If you primarily need a compact option for short trips or for a workstation lunch, this could be a good match.
Who it isn’t the best option for
If your priority is exact, scientifically verified temperature retention figures or you regularly feed a large appetite with sizeable portions, this model may feel a touch modest in capacity or in measurable performance data. If you plan to rely on precise hot-cold thresholds for sensitive meals, you may want to compare other options with more explicit test results. Additionally, if you routinely need to keep meals hot for very long periods beyond a day, you might find the capacity or insulation not perfectly aligned with those exacting expectations.
When it makes sense to buy
Consider this flask when you want a low-hassle, all-in-one meal container that travels easily. It’s practical for work, school, day trips, and light outdoor activities where you value container durability, ease of cleaning, and a lid that doubles as a bowl. If a single vessel for meals is the priority and you’re comfortable with typical, non-contrived temperature expectations, this Thermos model aligns with everyday value-for-money use.
What to check before you buy
- Confirm LEAKAGE and cap design details with your typical bag setup to ensure there’s no spill risk.
- Consider whether 470ml fits your typical portion size for a workday meal.
- Be mindful of the temperature figures as they vary by source, real-world results will depend on your initial temperature and the food type.
- Inspect the lid/bowl feature for compatibility with your usual eating and cleaning routines.
Practical use case
Imagine starting the day with hot porridge or a steaming curry, transferring it into the flask before you head out. By lunchtime, you can sip or pour from the same vessel without needing a bowl. In the afternoon, you switch to a chilled pasta dish or fruit and yoghurt, and the container remains comfortable to touch while on the move. This is the kind of day-to-day routine the design targets: simple, convenient, and flexible for various meals without extra washing up.
FAQ – quick answers where data allows
- What is the capacity? 470ml.
- How long does it keep meals hot or cold? The listing indicates up to 14 hours hot and up to 24 hours cold, though sources vary.

Final verdict
Final verdict: worth considering if you want a durable, all-in-one meal solution that travels well and reduces the need for extra dishes. It isn’t the most precise temperature guarantee on the market, and capacity is modest for bigger appetites, but for daily, practical meal management it provides solid value. If you prioritise simplicity, price-conscious durability, and the convenience of a bowl-in-a-lid setup, this Thermos model warrants a closer look.
