Why is a thermos called a 魔法瓶?


I just stumbled across this word today, and was baffled to find that a thermos
is a "magic bottle"? What reason is there for the kanji chosen? Was it a
decision by a company who introduced/manufactured the first thermoses in
Japan?




We had not understood the reason why a thermos is called 魔法瓶, but Mr.Awazu,
who was a director of 魔法瓶 memorial house, found out the reason a few years
ago.

He found out a oldest newspaper article which was written the word 魔法瓶 at
October 11th in 1907. The article said that in his interview about hunting, a
person referred to the high performance and convenience of a thermos, which
had been just imported to Japan at that time, and quoted 魔法瓶(Magic Bottle) in
Aesop’s Fable. His words were used in the oldest advertisement of a thermos in
Japan and he was decided to be the author of 魔法瓶.

However 魔法瓶(Magic Bottle) isn't in Aesop’s Fable and it seems to be his
misunderstanding.

This is the source.
