Emuva ngasekupheleni kwawo-1800, uWilliam Pate wasungula futhi wanikeza ilungelo lobunikazi ikepisi lebhodlela lamazinyo angu-24. Ikepisi elinamazinyo angama-24 lahlala lisezingeni lemboni kuze kube cishe ngawo-1930.
Ngemuva kokuvela kwemishini ezenzakalelayo, ibhodlela lebhodlela lafakwa ku-hose efakwe ngokuzenzakalelayo, kodwa ngesikhathi sokusebenzisa i-cap yamazinyo angu-24 kwatholakala ukuthi kulula kakhulu ukuvimba ipayipi lomshini wokugcwalisa othomathikhi, futhi ekugcineni kancane kancane ukulinganisa ikepisi yebhodlela lamazinyo angu-21 namuhla.
Ubhiya uqukethe inani elikhulu le-carbon dioxide, futhi kunezidingo ezimbili eziyisisekelo ze-cap, enye i-seal enhle, kanti enye iwukuba nesilinganiso esithile sokuvala, okuvame ukubizwa ngokuthi i-cap eqinile. Lokhu kusho ukuthi inani lama-pleats kukepisi ngalinye kufanele lilingane nendawo yokuxhumana yomlomo webhodlela ukuze kuqinisekiswe ukuthi indawo yokuxhumana ye-pleat ngayinye ingaba nkulu, nokuthi uphawu lwe-wavy olungaphandle kwekepisi luyanda kokubili. ukungqubuzana futhi kusiza ukuvuleka, nekepisi lebhodlela lamazinyo angu-21 libe ukukhetha okuphelele ukuhlangabezana nalezi zidingo ezimbili.
Futhi esinye isizathu esenza ukuthi inani le-serrations kukepisi libe ngu-21 lihlobene nesivuli sebhodlela. Ubhiya uqukethe igesi eningi, ngakho-ke uma uvulwe ngendlela engafanele, kulula kakhulu ukulimaza abantu. Ngemuva kokusungulwa kwesivuli sebhodlela esisebenzayo ukuvula ikepisi yebhodlela, futhi ngamazinyo asaha ashintshwa njalo, futhi ekugcineni anqume ukuthi isivalo sebhodlela sekepisi lebhodlela lamazinyo angama-21, elivulekile lilula futhi liphephe kakhulu, ngakho namuhla ubona zonke Izigqoko zamabhodlela kabhiya zinama-serrations angama-21.
