中國人發明了保溫瓶 or James Dewar?

My parents brought a few thermal bottles from their hometown as they could not find this kind of product in Western countries. They claim that only the Chinese invented the product. As I talked with some Western friends or colleagues, I was told that the principle of such products came from the inventor (cited literature below).

What do you think?

我的父母從家鄉帶來了一些保溫瓶,因為他們在西方國家找不到這種產品。 他們聲稱只有中國人發明了該產品。 當我與一些西方朋友或同事交談時,我被告知此類產品的原理來自發明人(以下引用)。

你怎麼看?

What is a liquid nitrogen Dewar?
A cryogenic storage dewar (named after James Dewar) is a specialised type of vacuum flask used for storing cryogens (such as liquid nitrogen or liquid helium), whose boiling points are much lower than room temperature. ... More sophisticated dewars trap the gas above the liquid, and hold it at high pressure.
