Thermos mug 0.35 L with button lid and lock, vacuum insulated, stainless steel 304, matte black — keeps 60 °C for 6 hours

Thermos mug 0.35 L with button lid and lock, vacuum insulated, stainless steel 304, matte black — a thermos for one person and half a day, which opens with one hand: press the button with your thumb — the lid flips open, drink like from a mug, without unscrewing and without removing your glove. A small slider-lock blocks the button so the lid doesn’t open in your backpack or pouch. The flask and body are made of stainless steel 304 with a vacuum between them: according to the manufacturer, the drink stays at 60 °C for 6 hours and 45 °C for 12 hours, cold drinks stay cold for up to a day. A plastic neck with a wide spout and air hole lets you drink in an even stream without gurgling; silicone seals don’t leak a drop in any position. Matte black powder coating doesn’t shine, isn’t slippery in a wet hand and doesn’t show scratches or fingerprints; Ø about 6.5 cm — fits in a backpack side pocket, a flask pouch, a car cup holder and a laptop bag pocket. Height about 22 cm, weight approximately 280 g.

In the section Thermoses, dishes and cutlery this is a thermos “for one person and half a day”: tea brewed in the morning, hot until noon. You can drink directly from it, but if hot tea is needed for two — pour into a 400 ml thermal mug or thermal mug with folding handles. The same thermos in olive color — 0.35 l thermos olive. Boil water for a thermos in the field — in a single-walled mug with folding handles on a pocket stove.

Instructions for use

1. Before first use, unscrew the lid, wash the flask and lid with warm water and detergent, remove and rinse the silicone seals, dry.
2. To keep tea warm longer, rinse the flask with boiling water and pour out. Pour the beverage no higher than 2 cm from the rim of the neck — the lid needs space.
3. Screw the lid on tightly. To carry, slide the lock slider — the button is locked.
4. To drink: remove the lock, press the button — the lid flips open; drink through the spout. Close the lid until it clicks, turn the lock.
5. After use, wash by hand with warm water, disassemble the lid; dry open. Not for dishwasher or microwave.

Once a week, remove the lid seal and wash separately — tea residue and odor accumulate under them. Residue in the flask is removed by baking soda or citric acid for an hour. Do not pour carbonated drinks, do not freeze, do not leave milk and compote for longer than a day — they spoil in heat. Do not drop: a dent on the body can destroy the vacuum.

Safety

Before opening the lid with a hot drink, place the thermos vertically and do not hold it above you — steam may escape when the button is pressed. Do not drink boiling water from the thermos while moving — first check the temperature with a sip. Do not pour boiling water to the brim: when closing, hot liquid is displaced. Do not use for milk, baby formula, and carbonated drinks under a closed lid. Damaged vacuum (the body became hot on the outside) — the thermos does not retain heat, it can only be used further as a bottle. Keep away from children with boiling water inside.

Specifications

Frequently Asked Questions

How long does it really keep heat?
Boiling water in the morning — after 6 hours about 60 °C (hot tea), after 12 — 45 °C (warm). In frost and in small volume a bit less: 350 ml cools faster than a liter. Rinsing the flask with boiling water before filling adds an hour or two.

Does it leak?
No, if the lid is screwed on tight and the lock is closed: the thermos lies in the bag on its side and upside down without drips. It only leaks if the silicone ring is worn or inserted incorrectly — you can see it when washing.

Can you drink while wearing gloves?
Yes, this is the main advantage of the button: you can unlock and press it with your thumb in a glove, no need to unscrew anything.

Does it fit in a car cup holder?
Yes, Ø about 6.5 cm fits in a standard cup holder and in door pockets.

Can you use it for coffee with milk and compote?
You can, but drink it the same day and wash immediately: milk and sweet things spoil in warmth, and the smell lingers in the seals for a long time. Carbonated drinks — no.

0.35 or more?
0.35 l — two cups of tea, for half a day for one person: commuting, travel, studying. For a whole day or for two people you need 0.75–1 l, but it won’t fit in a cup holder or side pocket anymore.

Black or olive?
The thermoses are the same. Black matte — universal: office, car, city, gift for anyone; scuffs don’t show on it. Olive — for hiking and forest, where you don’t need a contrasting object. There’s no difference in heat retention.
