Mbiri ya aluminiyamu screw caps inayambira kumayambiriro kwa zaka za zana la 20. Poyamba, zisoti zamabotolo zambiri zidapangidwa ndi chitsulo koma zinalibe zomangira, zomwe zimapangitsa kuti zisagwiritsidwenso ntchito. Mu 1926, katswiri wina wa ku America dzina lake William Painter anayambitsa kapu ya screw cap, kusinthira kusindikiza botolo. Komabe, zisoti zomangira zoyambirira zinali zopangidwa ndi chitsulo, ndipo sizinali mpaka pakati pa zaka za m'ma 1900 pomwe ubwino wa aluminiyamu unakwaniritsidwa.
Aluminiyamu, yokhala ndi zinthu zopepuka, zosagwira dzimbiri, komanso zosavuta kuzikonza, zidakhala zida zoyenera zopangira zipewa. M'zaka za m'ma 1950, ndi chitukuko cha mafakitale a aluminiyamu, zisoti za aluminiyamu zowononga zidayamba kusintha zipewa zazitsulo, kupeza kugwiritsidwa ntchito mofala mu zakumwa, chakudya, mankhwala, ndi zina. Zovala zomangira za aluminiyamu sizinangowonjezera moyo wa aluminiyamu wazinthu komanso zidapangitsa kuti mabotolo otsegula azikhala osavuta, pang'onopang'ono kulandiridwa ndi ogula.
Kufalikira kwa ma screw caps a aluminiyamu kunayamba kuvomerezedwa pang'onopang'ono. Poyamba, ogula anali kukayikira zakuthupi ndi kapangidwe katsopano, koma m'kupita kwanthawi, magwiridwe antchito apamwamba a zisoti za aluminiyamu adadziwika. Makamaka pambuyo pa zaka za m'ma 1970, ndi kukwera kwa chidziwitso cha chilengedwe, aluminiyumu, monga zinthu zobwezerezedwanso, zinakhala zotchuka kwambiri, zomwe zinachititsa kuti pakhale kuwonjezeka kwachangu pakugwiritsa ntchito zipewa za aluminiyamu.
Masiku ano, zisoti za aluminiyamu zakhala gawo lofunikira pamakampani opanga ma CD. Sikuti amangopereka kutsegula ndi kusindikiza mosavuta komanso amakhala ndi mphamvu yobwezeretsanso, kukwaniritsa zofuna zachilengedwe za anthu amakono. Mbiri ya aluminiyamu screw caps ikuwonetsa kupita patsogolo kwaukadaulo ndi kusintha kwa chikhalidwe cha anthu, ndipo kugwiritsa ntchito kwawo bwino ndi chifukwa cha luso lopitilirabe komanso kuvomereza kwapang'onopang'ono kwa ogula.
