Mu 1747, injeniyeri w’Umufaransa François Freneau yakoze ikoti ry’imvura rya mbere ku isi. Yakoresheje ikoti rya latex ryakuwe mu mbaho za kabuti, maze ashyiramo inkweto n’amakoti mu gitambaro muri uyu muti wa latex kugira ngo awutwikire mu mazi no mu gusiga, hanyuma ashobora kugira uruhare mu gutuma amazi adapfa.
Mu ruganda rw’imashini zitunganya imipira muri Ecosse, mu Bwongereza, hari umukozi witwaga Mackintosh. Umunsi umwe mu 1823, Mackintosh yakoraga maze agwa ku myenda ye ku buryo butunguranye. Amaze kuyibona, yihutiye guhanagura n’intoki ze, wari uzi ko umuti w’imashini usa n’aho winjiye mu myenda, ntabwo wahanaguye gusa, ahubwo warapfutsemo igice. Ariko, Mackintosh ni umukozi mubi, ntiyashoboraga kujugunya imyenda, bityo arayambara agiye ku kazi.
Bidatinze, Mackintosh yabonye: imyenda yasizweho ahantu hakozwe na karuboni, nk'aho yasizweho kole idapfa amazi, nubwo isa nabi, ariko idashobora kwangirika n'amazi. Yari afite igitekerezo, bityo umwenda wose wasizweho karuboni, umusaruro uba ukozwe mu myenda idapfa amazi. Hamwe n'ubu bwoko bushya bw'imyenda, Mackintosh ntagihangayikishijwe n'imvura. Iki gishya cyahise gikwirakwira, kandi bagenzi be mu ruganda bari bazi ko bakurikije urugero rwa Mackintosh maze bakora ikoti ry'imvura ridashobora kwangirika. Nyuma, kuba ikirangirire cy'ikoti ry'imvura ryarakuruye inzobere mu by'ibyuma mu Bwongereza, Parks, na we wize iyi myenda idasanzwe ku buryo bushimishije. Parks yumvaga ko, nubwo yasizweho imyenda ya karuboni idapfa kwangirika, ariko ikomeye kandi irakomera, kwambara umubiri atari byiza, kandi ko ari byiza. Parks yahisemo kuvugurura ubwoko bw'imyenda. Mu buryo butunguranye, iri terambere ryatwaye imyaka irenga icumi y'akazi. Mu 1884, Parks yavumbuye ikoreshwa rya disulfide ya karuboni nk'umusemburo wo gushonga karuboni, gukora ikoranabuhanga ridashobora kwangirika, maze asaba patenti. Kugira ngo ubu buvumbuzi bushobore gukoreshwa vuba mu bucuruzi, mu bicuruzwa, Parks yagurishije patenti ku mugabo witwa Charles. Nyuma yuko itangiye gukorwa ku bwinshi, izina ry'ubucuruzi rya "Charles Raincoat Company" naryo ryahise rimenyekana ku isi yose. Ariko, abantu ntibibagiwe icyubahiro cya Mackintosh, abantu bose bise ikoti ry'imvura "mackintosh". Kugeza n'uyu munsi, ijambo "ikoti ry'imvura" mu Cyongereza riracyavugwa "mackintosh".
Nyuma yo kwinjira mu kinyejana cya 20, havutse pulasitiki n'imyenda itandukanye idapfa amazi, ku buryo imiterere n'amabara by'amakoti y'imvura birushaho kuba byinshi. Ikoti ry'imvura ridashobora kugwa amazi ryagaragaye ku isoko, kandi iri koti ry'imvura rinagaragaza ikoranabuhanga ryo ku rwego rwo hejuru.
