Umlando we-vacuum flask ungalandelelwa emuva ekupheleni kwekhulu le-19.Ngo-1892, isazi sefiziksi nesazi samakhemikhali saseScotland uSir James Dewar wasungula i-vacuum flask yokuqala.Inhloso yayo yasekuqaleni yayinjengesitsha sokugcina kanye nokuthutha amagesi anoketshezi njengomoya-mpilo owuketshezi.I-thermos iqukethe izindonga ezimbili zezingilazi ezihlukaniswe isikhala se-vacuum.Le vacuum isebenza njengesivikelo, ivimbela ukudluliswa kokushisa phakathi kokuqukethwe kweflask nendawo ezungezile.Ukusungulwa kweDewar kwabonakala kuphumelela kakhulu ekugcineni izinga lokushisa loketshezi olugciniwe.Ngo-1904, inkampani ye-Thermos yasungulwa e-United States, futhi uhlobo lwe-"Thermos" lwafana namabhodlela e-thermos.Umsunguli wale nkampani, uWilliam Walker, waqaphela amandla okuqanjwa kweDewar futhi wakujwayela ukusetshenziswa kwansuku zonke.Wengeze ama-lining angaphakathi ane-silver-plated kumaflask engilazi aphindwe kabili, eqhubeka nokuthuthukisa ukufakwa.Ngokuthandwa kwamabhodlela e-thermos, abantu baye bathuthuka ekuthuthukiseni imisebenzi yabo.Ngawo-1960s, ingilazi yathathelwa indawo izinto ezihlala isikhathi eside njengensimbi engagqwali nepulasitiki, okwenza amabhodlela e-thermos aqine futhi afaneleke kakhulu imisebenzi yangaphandle.Ukwengeza, izici ezinjengama-screw caps, ama-spouts nezibambo zethulwe ukuze kube lula futhi kusebenziseke.Ngokuhamba kweminyaka, ama-thermos abe isisetshenziswa esisetshenziswa kakhulu ukugcina iziphuzo zishisa noma zibanda.Ubuchwepheshe bayo bokufaka izinto busetshenziswe kweminye imikhiqizo ehlukahlukene, njengezinkomishi zokuhamba neziqukathi zokudla.Namuhla, amabhodlela e-thermos afika ngezitayela ezihlukahlukene, osayizi kanye nezinto zokwakha ukuze avumelane nezidingo ezahlukene kanye nezintandokazi.
