Cov keeb kwm ntawm lub tshuab nqus tsev vacuum tuaj yeem taug qab mus rau qhov kawg ntawm xyoo pua 19th.Xyoo 1892, Scottish physicist thiab chemist Sir James Dewar tau tsim thawj lub tshuab nqus tsev vacuum.Nws lub hom phiaj tseem ceeb yog ua lub thawv rau khaws cia thiab thauj cov roj liquefied xws li kua oxygen.Lub thermos muaj ob lub iav phab ntsa sib cais los ntawm qhov chaw nqus.Lub tshuab nqus tsev no ua raws li cov khoom siv insulator, tiv thaiv cov cua sov hloov ntawm cov ntsiab lus ntawm lub hwj thiab ib puag ncig ib puag ncig.Kev tsim kho ntawm Dewar tau ua pov thawj tias muaj txiaj ntsig zoo hauv kev tswj xyuas qhov kub thiab txias ntawm cov kua dej.Xyoo 1904, lub tuam txhab Thermos tau tsim nyob rau hauv Tebchaws Meskas, thiab "Thermos" hom tau los ua ib qho kev sib txuas nrog lub raj mis thermos.Lub tuam txhab tus tsim, William Walker, tau lees paub lub peev xwm ntawm Dewar's invention thiab hloov nws rau kev siv txhua hnub.Nws ntxiv nyiaj-plated inner linings rau ob chav iav flasks, ntxiv txhim kho lub rwb thaiv tsev.Nrog rau qhov muaj koob meej ntawm lub raj mis thermos, tib neeg tau nce qib hauv kev txhim kho lawv txoj haujlwm.Nyob rau xyoo 1960, iav tau hloov los ntawm cov khoom siv ruaj khov xws li stainless hlau thiab yas, ua rau lub raj mis thermos muaj zog dua thiab tsim nyog rau kev ua si sab nraum zoov.Tsis tas li ntawd, cov yam ntxwv xws li lub hau hau, ncuav spouts thiab tes tau qhia rau kev yooj yim ntxiv thiab siv tau.Tau ntau xyoo, cov thermoses tau dhau los ua cov khoom siv dav siv los ua kom cov dej haus kub lossis txias.Nws cov cuab yeej rwb thaiv tsev tau siv rau ntau yam khoom siv, xws li cov mugs mus ncig thiab cov thawv ntim khoom noj.Niaj hnub no, thermos fwj tuaj nyob rau hauv ntau hom, qhov ntau thiab tsawg thiab cov ntaub ntawv kom haum raws li cov kev xav tau sib txawv thiab nyiam.
