0.4 L insulated stainless steel hiking and camping flask 900, instant stopper.

We’ve tested this food storage container in the lab according to the EN 12546-1 Standard, at an ambient temperature of 20°C, and filled to capacity. The time it takes to drop from 95°C to 50°C (drinks temperature considered warm enough to drink) is more than 23 hours.

This insulated flask’s stainless steel double wall with vacuum blocks heat by conduction and convection.A thin layer of copper reduces thermal exchanges by radiation.A few tips to improve thermal insulation:fill your bottle with warm water for 5 minutes, and then replace the water with your hot liquids, then close.The fuller the bottle, the better the heat retention.Warning: this flask is very insulating, the liquids will remain hot for a long time

You can open the quick-release cap with one hand by lifting the white latch. You close it by pressing the latch down or by screwing the cup back on.A removable tea filter is attached to the cap. Simply pull on it to separate it from the cap. Be aware that if you remove the filter after immersing it in hot water, it may be boiling hot to touch.The cup screws onto the bottle, making it easy to carry around, and is made from double-walled stainless steel with no air space.
