I tried to verify the heat insulation capacity of the ultra-high performance heat insulation bottle 'mountain exclusive bottle' that cools only about 6 ° C in 7 hours and see if it is useful for everyday use.
'Mountain-only bottles ' are stainless steel bottles that have higher heat retention than ordinary vacuum-insulated bottles and are designed for mountaineering, such as the shape of the rubber cover and lid. I was wondering how much performance the mountain bottle optimized for mountaineering would show if I used it indoors like a normal bottle, so I actually kept the heat of the mountain bottle and the general stainless steel bottle. I compared the abilities.

◆ 1: Appearance review of mountain bottles
There are 3 capacities of 500ml, 750ml and 900ml in the mountain bottle, and each has a color lineup of 3 colors. This time I will use 750ml clear stainless steel. Snowy mountains are drawn on the package, creating an atmosphere that seems to be suitable for full-scale mountain climbing.
At the bottom of the package, it says 'Keep 78 ° C even after 6 hours', emphasizing the high heat retention capacity.
Open the package and take out the contents.
Inside was a mountain bottle body, an instruction manual, and a card with contact information.
The mountain bottle looks like this. The yellow part of the bottom and body is made of silicone rubber, and the silver part is made of stainless steel.
Thanks to the silicone rubber attached to the torso, the lid can be opened and closed without slipping even when wearing gloves.
In addition, the silicone rubber on the bottom and body is removable ...
The weight can be reduced from 354g when wearing silicone rubber to 319g.
The lid can be used as a cup. In addition, the plug has a double structure of an external plug (lower side) and an internal plug (upper side).
When refilling a mountain bottle with drinks, you can remove both stoppers.
And when pouring a drink into a cup, twist only the internal stopper. If you twist it about half a turn and then tilt it with the triangle mark down ...
Drinks will come out from the part marked with a triangle.
◆ 2: I compared the heat retention capacity of mountain bottles and general bottles.
In order to check the heat retention capacity of the mountain
It was placed in a room with a temperature of 25 ° C, the stopper was removed every hour, and the temperature was measured with the
First, the temperature immediately after adding boiling water was 83.8 ° C for the mountain bottle (left) and 79.9 ° C for the general stainless steel bottle (right). I poured boiling water almost at the same time, but there is a difference in temperature due to the difference in capacity.
Six hours after pouring hot water, the temperature of the mountain bottle (left) was 78.8 ° C, and that of a general stainless steel bottle (right) was 54.4 ° C. The mountain bottle performed as described on the package.
The graph below shows the change in temperature every hour. The temperature of the mountain bottle was very gradual, and even 7 hours after pouring hot water, it kept a high temperature of 75.6 ℃.
◆ 3: Summary
As a result of verifying the heat retention capacity of the mountain bottle in a room with a temperature of 25 ° C, we were able to confirm the high capacity that the temperature drops only 6.2 ° C in 7 hours. If you put boiling water in the mountain bottle, you can keep it hot for a long time, so 'boil the water in the kitchen and bring it to your room and use it as a pot' 'Boil the water in the morning and put it in the mountain bottle and work at the desk It is also recommended for indoor purposes other than mountain climbing, such as 'making coffee and tea.'
